    - Is there a way we can send a feature request for Visual Studio? Hi, Is there a way we can send a feature request for Visual Studio? When using 'Refactor-->Encapsulate Field', I'd like to have an option for the references not to be updated anywhere in the project. It would be very useful for me (and probably others too) because I use this feature to generate my properties from my member variables. So I type all my member variables and then take them one by one and encapsulate them... When the project is small it's quick and efficient, but when the project becomes bigger it can take many seconds and sometimes minutes because it searches in all the assemblies of the solution to update the reference to a private variable that is not used anywhere because I just created it. Moreover, it would be nice to take a block of member variables and tell Visual studio to encapsulate them all. It would save a lot of time (and money too). So to reiterate my question : Is there a way (or place) we can send a feature request for Visual Studio? thanks ThunderMusic Tag: Framework 2.0 compatibility issues with Component Services Tag: 121941

    - Using remoting features inside a .NET applet loaded in a tag object First of all, is it possible usign .NET remoting feature inside a .NET applet loaded into a tag object inside an HTML page ? <OBJECT id="myID" height="150" width="300" classid="http:applet.dll#test.applet"> </OBJECT> If not please can anyone explain why ? I think yes and so I'd written a small example immediately I've met a problem. I'm using .NET Framework v. 1.1.4322 and it's the only version installed both client side and server side. My test applet is correctly loaded into IE client but when I try to setting programmatically the remoting I aways obtain a SecurityException even if the assembly is strong name signed and client side fully trusted. The exception is the following: System.Security.SecurityException: Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed. at System.Security.CodeAccessSecurityEngine.CheckTokenBasedSetHelper(Boolean ignoreGrants, TokenBasedSet grants, TokenBasedSet denied, TokenBasedSet demands) at System.Security.CodeAccessSecurityEngine.CheckSetHelper(PermissionSet grants, PermissionSet denied, PermissionSet demands) at System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(IChannel chnl) at test.applet.Check() Could anyone help me please ?

    - Directory (LDAP) search error 0x8007203A Hi, I'm trying to read some data with C# in .NET 2.0. I'm using the Directory classes as follows: ... DirectoryEntry entry = new DirectoryEntry(); entry.Path = "LDAP://myServer.intern.myCompany.de:51000/ou=MyApplication,ou=srv,o=myCompany"; entry.Username = LDAP_APP_USER; entry.Password = LDAP_APP_USER_PSWRD; DirectorySearcher searcher = new DirectorySearcher(entry, myFilter); SearchResultCollection results = searcher.FindAll(); foreach(SearchResult result in results) ... results.Dispose(); ... The values for Username, Password and Path (and myFilter) are correct and access works fine within other acess software like Jxplorer. But here, unfortunately the call "searcher.FindAll()" throws a System.Runtime.InteropServices.COMException: "0x8007203A: The server is not operational". (Translated English version, we use VS2005 German) I have no idea what to do! Thx for your appreciated help! - Harald Tag: Framework 2.0 compatibility issues with Component Services Tag: 121939

    - Problem with timeout in TransactionScope Hello, I'm porting my application from ServicedComponents to TransactionScope objects. One of the most fun features of new tech is that it allows transaction timeouts more then 10 minutes. My application has many layers and using SqlTransactions is not convinient. As I undestand if TransactionScope is created with TimeSpan.Zero timeout then transaction manager doesn't control transaction time. But actually the transaction is aborted after 10 minutes timeout set in Machine.config. It is true for both SQL 2000 & SQL 2005. If transactions were created explicitly via CommitableTransaction class, this limitation didin't appear ( but only for SQL 2005, SQL 2000 transaction still were aborted ). After explanation of System.Transaction code via Reflector utility I found that TransactionScope always checks timeout via TransactionManager.ValidateTimeout method while CommittableTransaction doesn't. I guess the the problem can be resolved by changing maximalTimeout in machine.config but it is not applicable in the concrete case. I'm wondering is such behavior of TransactionScope designed? Can I rely that CommittableTransaction preserves this behaviour in the next versions or .NET? Thank you for your attention. Vladimir.

    - Intellisense in ASP.NET textbox Hi, Do you know how to implement intellisense behaviour in ASP.NET textbox. Like in destination textbox at http://www.booking.com/ site? It shows cities from all over the world and it works extremely fast. I think it's some sort of partial callback? When I save page i have list only of cities that match first letters. So there is no big XML file. Looking in cache i saw that each string i've entered it shows links example http://www.booking.com/lookup.html?str=new (for new york) Do you know if somebody sells component like this or have any other idea how to do it?

    - How to determine if I am in a web or a windows application Hello to all, I use a lib class to handle all my exeption errors ocured in my objects.

    - GC problem with large object - .net 1.1 Hello, I have an applications witch works with bitmaps. Such bitmaps are in windows (forms) sizeable. Each time it is neccary to allocate new bitmap with any size-step, because the bitmap is generated. So there is the following situation under .net 1.1 If the window (bitmap) is sized for exampel 10 bitmaps are generated and disposed in 2 seconds. Because the GC does not make garbage collection directly, this costs 10 MB ram instead of 1. If it is exreme, an application which needs realy 10 MB - you see in the taskmanager 50 MB. But this is the first layer of the problem. Now some time later, maybe the GC makes a garbace collection. Now GC-Memory has 10 MB used and 40 MB free. BUT the GC does not give the memory back to the system. (sometimes GC gives a little back to the system, but not all). Means: for a long time you see 50 MB RAM resources used in the tasks manger, what is not the reality, it's only 10 MB. This problem is very hard, because customers see this in the task manager und do not buy the product. So question: Is there any way under dot net 1.1 (.net net 2.0 is absolute impossible in the moment because of many reasons), to reduce the shown used Memory, which is wrong in the taskmanager for this app. Means is it possible to solve the problem when the bitmap is sized that memory is not accumulated, because with each new bitmap the old is disposed. I think there will be no solution under .Net / C#, but would be fine. But also a solution using C++ / unmanged code would be nice. (for the allocation of memory of the bitmaps only). Thank you for any help. Rolf Welskes Tag: Framework 2.0 compatibility issues with Component Services Tag: 121917

    - Install font from ClickOnce application How can I distribute a TrueType font with my Windows Forms application using ClickOnce? Is there a direct/supported way to install via ClickOnce? I tried including the ttf files as resources and copying to the fonts folder on startup. This worked fine, but I can't manage to get them 'registered' properly (in spite of making registry entries and api calls for AddFontResource, CreateScalableFontResource, and SendMessage). These calls appear to work, but I still can't use the font. So, if there is no direct way to install with ClickOnce, any advice on doing the work from C# would be appreciated.

    - Dynamically instance a class I have a setting in my database where the user specifies a tax configuration (e.g. "UK/EU") and I have several tax classes that handle these different configurations. So what is the best way to instance the proper class based on what is in this configuration parameter. I could use a simple switch statement but it seems like there should be a better way.

    - bug with SelectedIndices collection in virtual ListView There seems to be a bug when using a ListView control in virtual mode. If you check the SelectedIndices property of your list view within the SelectedIndexChanged event, and the user Shift-Selects a range of items in the listView, the number of selected indices is always zero. The returned list of selected indices is correct if the user uses the ctrl-select, or just simple selects from the list. This happens when the view property is set to "Details". Of course, you must have the MultiSelect property set to true and the VirtualMode set to true as well. Is there a work-around/fix available for this?

    - Event handling (C# vs VB6.0) I have the following code in C# to "sink" an event with an event handler. Obj.OnCallEvent +=new CallEventHandler(obj_OnCallEvent); obj_OnCallEvent being the actual method and "obj.OnCallEvent" is the actual event. This events are provided by a 3rd party Dll. I have converted that dll into a type library and used it in VB6.0 However, I'm not sure how to "sink" events in VB6.0! Please advise what would be a compatible statement in VB6.0 for above C# code?

    - Windows .Net 2.0 Application - Exception from HRESULT: 0x80070542 We have installed an .Net 2.0 windows application onto one of our clients PC's and we are experiencing some problems. When the application starts it tries to connect to a database in order to retrieve some information. Given below is an extract of the thrown error:- "System.IO.FileLoadException. Could not load file or assembly 'System.Transactions.............' or one of it's dependencies. Either a required impersonation level was not provided, or the provided impersonation level is invalid (Exception from HRESULT: 0x80070542)" We believe that this error occurs due to the permission's of standard clients domain users, as if you log onto the client PC with administrator privileges the application can connect to the database without a problem. This assemblies are installed into the GAC on the PC, other .Net GAC assemblies run on the PC ok. I do not no anything about restrictinng desktops, therefore what restrictions would be within the user accounts to prevent this. Any ideas will be most appreciated as I am currently at a total loss Tag: Framework 2.0 compatibility issues with Component Services Tag: 121882

    - Are named pipes quicker than just reading and writing to files? Hi all, I've been looking into doing some interprocess communication and have been reading about named pipes. Everyone seems to indicate that if the processes are either on your local PC or at least on your local LAN AND your messages are reasonably small (under a kilobyte) - then named pipes are the right solution. But all of the implementations I've seen seem to just be writing and reading to a file. Is named pipes just a marketing term for regular old file I/O. Here are the two implementations I've looked at: http://www.codeproject.com/csharp/DotNetNamedPipesPart1.asp http://i-d-e-a-s.blogspot.com/ I think the second URL provides a more concise implementation so that I can more easily use the code myself in my own project. As opposed to the first one - which while well architected in design all comes with lots of classes, interfaces and even a prebuilt dll to which you don't have the source. Am I gaining anything by using the implementation in the second URL over just using a regular write and read to and from a file? If not, is there some inter-process code that is relatively concise that would be superior to just reading and writing to a file? Thanks, Novice Tag: Framework 2.0 compatibility issues with Component Services Tag: 121874

    - Here is some as-is code for helping with System.Diagnostics.Process Thought I would throw this out there so that it could be Google'd. Deals with a common use of Process which is to encapsulate another process and grab its standard out and standard error, and so it uses the asynchronous operations that the Process class provides.

    - Async UI Calls Block on Dual-Core CPU, work fine on Single Core. Why? I am using the code from this MSDN article http://msdn2.microsoft.com/en-us/library/bz33kx67.aspx Everything worked great on my single core CPU laptop. I then tried to run the .exe on my Dual core Pentium-D at work. The UI becomes unresponsive while the background thread is running. When I go into task manager and change the CPU affinity from 0,1 to just 0, the UI becomes responsive again. Please keep in mind that made the loop longer so that I have time to observe the blocking.

    - Async activities from class not derived from Control I want to create a utility class which is defined as follows: public Class MyDataReadingClass { ... } In that class I want to encapsulate all the logic for performing certain SQL Server queries and have the result set accessible from my parent, which will always be a System.Windows.Form object. My problem is that since my class is not derived from Control, I do not have access to Invoke() in my async callback handler, where I would normally pass my SqlDataReader via Invoke to a safe place from which its contents can be accessed without synchroniziation issues. It seems silly to be deriving my utility class from Control when it is not really a control, but I want to be able to create instances of my data reading utility class in different places in my applications.

    - System.ComponentModel.BackgroundWorker runs DoWork handler twice Hi, Using Visual c# 2005 express, I have a Form which utilises a button click to start a BackgroundWorker thread. The thread calls a Soap proxy class, derived by web reference, to consume a web service on a server. Each time it runs, it runs the DoWork event handler code twice! I've tried adding a second event handler in to the DoWork event. That one only ran once whilst the Soap service consumer one still ran twice. The code snippet below is the actual code for the button click, and event handler codes, with the following notes: - all the methods below are part of the Form class - SoapClass represents the web reference derived class. - the actual winform is a simple form with a username text field, password text field and connect button. it's very simple so I thought it a waste of space to post all the form supporting code. Any clues as to why this would happen? Cheers Ian <code> private void InitializeBackgoundWorker() { this.backgroundTask.DoWork += new DoWorkEventHandler(backgroundTask_DoWork); this.backgroundTask.RunWorkerCompleted += new RunWorkerCompletedEventHandler( this.backgroundTask_RunWorkerCompleted); } private void backgroundTask_DoWork(object sender, DoWorkEventArgs e) { SoapClass.apiResponse objFinalResponse ; SoapClass.clientAuth objClientAuth = new SoapClass.clientAuth(); SoapClass.apiAuth objApiAuth = e.Argument as SoapClass.apiAuth; SoapClass.apiService objApiService = new SoapClass.apiService(); objFinalResponse = objApiService.Authenticate(objClientAuth, objApiAuth); e.Result = objFinalResponse; } private void backgroundTask_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Error != null) { MessageBox.Show("Failed!"); } else if (e.Cancelled) { MessageBox.Show("Cancelled!"); } else { SoapClass.apiResponse objFinalResponse = e.Result as SoapClass.apiResponse; MessageBox.Show(objFinalResponse.code); } } private void connectButton_Click(object sender, EventArgs e) { SoapClass.apiAuth objApiAuth = new SoapClass.apiAuth(); objApiAuth.username = this.username.Text; objApiAuth.password = this.password.Text; this.backgroundTask.RunWorkerAsync(objApiAuth); } </code> Tag: Framework 2.0 compatibility issues with Component Services Tag: 121858

    - Hang when new DirectoryEntry declared I am using the System.DirectoryServices namespace in .net 2003. I have noticed some very strange behaviour related to the DirectoryEntry class. If I debug the following code with a break point on the Console.WriteLine line then there is a lengthy pause before the breakpoint is hit. If I remove the DirectoryEntry line then the breakpoint is hit immediately. static void Main(string[] args) { Console.WriteLine("Test"); DirectoryEntry dirEntry = new DirectoryEntry(); } Also this only happens when I am debugging in Visual Studio. If I run the console app on its own there is no pause. The only thing I could come up with initially was that maybe there was a static constructor that was firing, but this didn't really seem to make sense and looking at the source for the DirectoryEntry class I can't see anything that would account for this pause. Any ideas would be appreciated. Regards Ian Tag: Framework 2.0 compatibility issues with Component Services Tag: 121857

    - Dowload File Hi, I have problem with downloading a file using WebRequest and HttpWebResponse. Inorder to download this file i need to call to url that tells to prepare the file for download, and then i call to another url that downloads the file. I have a problem with that because: 1. i do not know when the server finished the preparetion. 2.i checked the HttpStatusCode but he doen't changes (myresponse.StatusCode). the problem causes the application to download only a part of the file and that because the server hasn't prepared the file yet. if i give him Thread.Sleep(100000) i do get the full file, but the file can be 100Mb and 10sec won't help. the code is: //Preparing the file todownload... //--------------------------------------------------------------------------------------------------------- HttpWebRequest webRequest3 = WebRequest.Create(d1) as HttpWebRequest; webRequest3.KeepAlive = true; webRequest3.Headers.Add("Keep-Alive", "300"); webRequest3.Headers.Add("Accept","text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"); webRequest3.Headers.Add("Accept-Language", "en-us,en;q=0.5"); webRequest3.Headers.Add("Accept-Encoding", "gzip,deflate"); webRequest3.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7"); webRequest3.CookieContainer = cookies; HttpWebResponse myResponse3 = (HttpWebResponse)webRequest3.GetResponse(); Thread.Sleep(10000); Stream ReceiveStream3 = myResponse3.GetResponseStream(); //----------------------------------------------------------------------------------- //Downloading .... //-------------------------------------------------------------------------------------- Console.WriteLine("Connecting to download link..."); HttpWebRequest webRequest2 = WebRequest.Create(re) as HttpWebRequest; webRequest2.ContentType = "application/x-www-form-urlencoded"; webRequest2.KeepAlive = true; webRequest2.CookieContainer = cookies; HttpWebResponse myResponse2 = (HttpWebResponse)webRequest2.GetResponse(); Stream ReceiveStream2 = myResponse2.GetResponseStream(); Console.WriteLine("Downloading..."); Common.SaveStreamToFile(@"C:\scrapingtest\file.csv", ReceiveStream2); Console.WriteLine("Done Downloading"); Thanks, Rony Tag: Framework 2.0 compatibility issues with Component Services Tag: 121851

    - MSBuild and VSTS 2005 Forgive me if this is the inappropriate forum to post this, but I found MSBuild.exe in the framework directory so it seems right to me:-) Also forgive me if this duplicates an existing post. I posted this issue the other day, and it seems to have disappeared. (I have way too many posts not be there when I look for them!!!) Finally forgive me that this posting is not as complete as the original. I've made progress so I've had to leave out the error numbers that were part of the original. Now on to the issue: The MSBuild documentation implies that all you have to do is point it at the proj files maintained by the IDE and it will run. It appears to be even nicer than that. Start MSBuild in a folder with a single sln file and it will find and use it. Impressive! HOWEVER, it may or may not run without modification to the projects. I've had to do both of the following: 1) Add references to a library that was lower in the inheritance stack than those needed by the IDE. The projects being compiled didn't refer to this library, but forms were derived from forms that did refer to the library. (I've lost track of how many layers deep the inheritance of the main program window is from Windows.forms.form. It's a bunch.) 2) I had blanks in the names of icons included in the resources and they had to be removed. This has been documented by others elsewhere. I finally came to a show stopper. I'm getting C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets(2071,9): error MSB3188: Assembly BLAHBLAHBLAH must be strong signed in order to be marked as a prerequisite. No place have i marked BLAHBLAHBLAH as a prerequite. I'm not using strong signing precisely because "the directions" which i've actually read of a change discourage it for my target environment. I get this error occasionally in the IDE with various of the libraries in the project being the culprit. To solve the problem there, i just zap all the bin and obj folders and rebuild. (I zapp directories so frequently I wrote a program to do it. It's usually because forms get errors when I attempt to display them.) Zapping directories immediately before calling MSBuild makes no difference. SUGGESTIONS please.

    - Announcement: NLog 1.0 has been released NLog 1.0 has been released.! After 2 years of work, we're proud to announce the availability of NLog 1.0. NLog is a FREE logging library for .NET designed with simplicity and flexibility in mind. See http://www.nlog-project.org for more information about NLog. Source, binary packages and installer packages are available for download from: http://www.nlog-project.org/download.html Tutorial and reference documentation are available at: http://www.nlog-project.org/documentation.html The following people have contributed to NLog by submitting code or bug reports: * Jaroslaw Kowalski <jaak at jkowalski dot net> * Marcin Krupinski <yoszek at gmail dot com> * Inez Korczynski <korczynski at gmail dot com> * Rafal Gwizdala <gwrafal at poczta dot onet dot pl> * Yuri Mamrukov <yvm at att dot net> * Maciej Figatowski <mfigatow at sav dot net> * Perry Rapp <lifelines_3_0_18 at hotmail dot com> * Maarten Claes <m.claes at farcourier dot com> The focus of this relase is future compatibility. Code has been added to ensure that the development of NLog will progress without breaking existing code. The following paragraphs describe changes that made after 1.0 RC1 release. Breaking API changes: * Added NLog.ILayout which Layout implements to allow other layout types (such as CSV-escaped, HTML-colored, XML-escaped, ANSI-colored) to be implemented. * NLog.Layout became sealed. * FileTarget.KeepFileOpen is back to the default of false. we now have <default-target-parameters /> so this default can be easily overriden. * Added NLog.TargetWithLayout, removed Layout and CompiledLayout from NLog.Target * Removed CSVFile target, converted examples to File + CsvLayout * Removed LogEventInfo.Empty and replaced with LogEventInfo.CreateNullEvent() * Changed the default value of FileTarget.OpenFileCacheTimeout to -1 Packaging changes: * Added publisher policy generation and established NLog versioning policy. See http://blog.jkowalski.net/?p=55 for more information about NLog versioning policy. * Build number is synchronized with SVN number. * Added VJSharp and Web item templates. Updated the installer to support VWD Express 2005. * Synchronized Visual Studio solutions to source code directories. Now part of the build process. * New NLog.Benchmark that uses code generation and compilation to create more "clean" environment. Changes to the logging infrastructure: * Added <targets><default-target-parametes /></targets> that specifies default values for all targets in the section * Added Initialize() and Close() to the LayoutRender class * Added optimized CurrentTimeGetter which is way faster than DateTime.Now * Fixed LayoutRenderer.ApplyPadding() null handling * Added infrastructure to create your own logger types inheriting from Logger: LogManager.GetLogger(string name, Type type) LogManager.GetCurrentClassLogger(Type type) LogFactory.GetLogger(string name, Type type) LogFactory.GetCurrentClassLogger(Type type) * Added PopulateLayouts() method to ILayout * Added ${event-context} layout renderer that extracts information from LogEventInfo.Context * Added LogManager<LoggerType> that manages logger instances of LoggerType where LoggerType : Logger * Added support for nested layout renderers. Used in ${file-contents}: ${file-contents:fileName=${basedir}/aaa.txt} * Added support for DEFAULT nested layout parameters. You can now write: ${file-contents:${basedir}/file.txt} ${rot13:URYYB} * Added pluggable layouts (CSV, Log4JXml), LayoutFactory and LayoutAttribute. The syntax is: <target xsi:type="File"> <layout xsi:type="CSVLayout"> <column name="message" layout="${message}"/> <column name="level" layout="${level}"/> </layout> </target> Of course the old syntax is still supported for simple layouts: <target xsi:type="File" layout="${message}"/> * Added ILayoutWithHeaderAndFooter for layouts that support header/footer (such as CSV Layout, more to come) * Enhanced XSD Schema generation by properly generating abstract and layout properties. * Added FilterResult.IgnoreFinal and FilterResult.LogFinala which suppress processing of further rules if the filter matches. * Added NLogConfigurationException which is thrown instead of CLR exceptions when the configuration fails * Simplified XmlLoggingConfiguration by splitting large methods and moving common functionality to PropertyHelper * Added [DefaultParameter] attribute which allows for nameless parameters to layout renderers: ${aspnet-application} ${aspnet-request} ${aspnet-session} ${date} ${environment} ${file-contents} ${gdc} ${mdc} ${process-info} ${special-folder} ${asp-application} ${asp-request} ${asp-session} * Moved the implementation of LogManager to a reusable LogFactory while maintaining its public interface. You can noweasily have a private LogManager for an assembly. New additions: * Added MaxMessageSize (default: 65000) and OnOverflow (default:Split) to the Network target * Implemented headers and footers for the File target. CAUTION NLog automatically writes footers for files that have not been written for 2 days (48 hours). This is done do conserve memory for long-running processes that create lots of log files. * Enabled DatabaseTarget.ConnectionString to include layouts. * Added eventID and categoryID parameters to EventLog targets. * Added ${file-contents} layout renderer which inserts file contents. * Added MailTarget.AddNewLines to insert new lines between header/lines/footer * Added FormControl target that logs to Text property of any Windows.Forms.Control * Added RichTextBox target with row- and word coloring that logs to RichTextBox * Added ${tempdir} and ${specialfolder} * Added ${gc} which can be used to get the GC statistics (very limited) * Added ${processinfo} which can be used to extract the performance information about the current process (possibly others in the future as well) * Added ImpersonatingWrapper which temporarily changes the credentials for the duration of the write. * Added NLog_Init() and NLog_InitLocal() APIs to NLogC Bug fixes: * Fixed File target for Windows 98 * Fixed Network target to work properly with IPV6 * Changed RichTextBox Target to be thread safe. Uses delegate to log to RichTextBox Documentation updates: * Added examples of inheriting from Logger class and wrapping it * Added missing code documentation * Added example ${rot13} layout renderer - that demonstrates how wrapper layout renderers can be written. * Added proper camelCasing to the web build process * Fix for multiple email addresses being passed in To,CC and BCC fields under .NET 2.0 (reported by Pawel Parzychowski) Tag: Framework 2.0 compatibility issues with Component Services Tag: 121840

    - Strange problem in asynchronous webrquest processing. Hi all, I am facing one strange problem while processing webrequest asynchronously. I am processing say 3 webrequest asynchronously. I have added try-catch block in all methods. This app is running continouously. It was working properly for say half an hours. I am running application in debugging mode. Suddenly my application displayed error message 'unable to supprt transport connection' with exception type as system.io.ioexception. I clicked on debug to find out error. It went to disassembly part wherein i couldn't find reason for this error. Then i restarted my application to simulate this error. But then app is working fine. I don't know what is happening here. Can someone tell me why this is happening. and why exception is not getting catched in exception handling block even if i have added it in all function. Please help me. thanks in advance.

    - vista? I have a very basic question. If your going to start out with vista development is it a lot better to try to develop with Vista RC1 or is it almost or just as good to use XP with Framework 3 installed? Vista is slugish at this point and i want to do most of my development in a virtual machine (i don't install Non-Release software on my main machine as a rule). I would like to use XP if i can but if i cant i can't and since i haven't delved into it yet then i don't know. thanks, Brent Tag: Framework 2.0 compatibility issues with Component Services Tag: 121827

    - How to determine when a process has finished initial loading Hello, Is there a standard way of determining when a process has finished its initial loading, such that it is ready to accept commands? For example, I am starting Visual Studio (devenv.exe) from my own program. I would like to perform some actions (like open a file), when Visual Studio is ready. Is there a way to test when an application has finished displaying its main window and is ready to accept user commands?

    - Bug Log for Microsoft // Missing Enum Value in Framework Is there an official "bug report" location, to report a DotNet framework bug? I don't like to throw out the "bug in the framework" thing very often, but I think I've done the homework on this one. .. I've found an enum value that doesn't exist: public enum MessageQueueErrorCode It doesn't contain a value for -1073741536 The condition where this would happen is .... // register a handler ... OnPeekCompleted _queue.BeginPeek(); private void OnPeekCompleted(object sender, PeekCompletedEventArgs e) { _queue.EndPeek(e.AsyncResult); } If the queue is empty when this code starts, it throws a MessageQueueException exception. with MessageQueueErrorCode = to that number above. I used this code to loop over the enum foreach (string s in Enum.GetNames(typeof(MessageQueueErrorCode))) { string name = s; MessageQueueErrorCode t = (MessageQueueErrorCode) Enum.Parse(typeof(MessageQueueErrorCode),s); int val = (int) t; if (val==-1073741536) { string didIFindIt = "bingo"; } } and its not there. If you google search it: http://www.google.com/search?hl=en&lr=&q=1073741536+MessageQueueErrorCode&btnG=Search You find lots of people mentioning it. However, I haven't seen any "Ahh, its a missing enum value" And here is another "hint" that it is missing: http://www.koders.com/csharp/fidE632059BF610D9D912C019A96DCF7A2DD76C847F.aspx Tag: Framework 2.0 compatibility issues with Component Services Tag: 121818

    - Server Access I am replacing a VB6 batch program with NET 2003. The program is launched from a SQL Server via DTS, and the first thing the program does is read some information from a file (DAT/INI type) residing in the same folder as the exe. The VB6 programs works just fine, but the NET 2003 errors out with "System.Security.Permissions.SecurityPermission at MyProgram.basMain.ReadDAT". What do I need to do to get access? This server\share is readable by all within the enterprise, so I'm guessing this is some sort of framework issue.

    - solution for dbase (*.dbf) jet c# (or vb) problem with ole or odbc (can't find table) I had some problem with dbase. I was working on dbf files with ole connection. Once, when I wanted to see very big table connector sait that he can't find this table. Same was when I used odbc. As I looked at Microsoft support pages on one hand I should update my Jet driver (for XP) because there as a bug in older version, but on the other I shouldn't because I got most new one or my language was different than update langage (PLK != PLK [sic!]). So. The real reason wat that dbase files were createn with BDE. Somethimes Jet can't just read them. sollution? It supprised me much. Just install some version of BDE. BDE overrides jet. Now it works fine. Hope it would help. Tag: Framework 2.0 compatibility issues with Component Services Tag: 121808

    - Personal Web Starter Kit I created my first WEB application from Personal WEB Starter Kit template (C#). I made just minor changes like Connection String and some texts. I created SQL Server database on the hosting server and I uploaded all files to the hosting server. I ran my site http://www.srssite.com and everything was fine. I uploaded 1 picture and tested my site again. I noticed just a very small difference in speed (opening default page initially and coming back to home page from other pages). Then I added more pictures. The speed became more slow. The more pictures I'm adding the slower my site works. To be sure that this is the problem related to the number of pictures I created another SQL Server database on another hosting server and repeated my steps - first run without any pictures (the site is very fast), added a few pictures (the site became slower), more pictures - more decrease in speed. Alrhough I'm a very beginner I suspect that there is some problem with the design of this template. I've read before many times that it's a bad idea to store pictures in a database, but this template is using this approach. Is there anybody who changed this scenario to another one which stores pictures on the drive and their names and paths in a database? If yes, could you give some advice how to change the code. Thank you Esha Tag: Framework 2.0 compatibility issues with Component Services Tag: 121798

    - Socket weirdness See some strange results on Send and peer with a closed Receive. Setup a test harness. Server accepts socket, then just does a Shutdown.Receive right away and waits. The client socket does both blocking Sends and BeginSends to see the difference in behavior. Results: 1) Using blocking Sends - The first send returns 10, which is the buffer size. Future Sends, return 0 and no exception. This behavior seems not to fly with the doco. The send should block until 10 bytes are sent to kernel mode or throw an exception, *not return 0. Note the socket is in blocking mode (default setting). 2) Using async BeginSend gives completly different results. The first EndSend returns 10 as above. The second BeginSend returns a null IAsyncResult and sets SocketError to "ConnectionReset". I find this behavior very strange. BeginSend should never return a null IAsyncResult as that FooBars the async pattern (it should always return IAsync or exception). It should save the exception for the EndSend call. Second, why does it set SocketError to ConnectionReset, when blocking Send does not seem to care. The two behaviors should be consistent. 3) Also, what is the point of SocketError being an out parm? It should just be included in the SocketException and thrown - no? TIA -- William Stacey [MVP] Tag: Framework 2.0 compatibility issues with Component Services Tag: 121795

Hi,

I developed a system using VS2003 and framework 1.1. Middleware developed in
C# and VB 6.0.

Since I have to go through COM+, my application installs fine when the
framework is 1.1. However when I install 2.0, the application (proxy) does
not work properly. I get an error 80020009. I'm runnning XP.

Does anybody know if there is a hotfix or something else to do?

Thanks,

Top
