    - Reading Files in Worker Threads I use the following method to read a file: static byte[] ReadFile(string path) { FileStream stream = new FileStream(path, FileMode.Open); BinaryReader reader = new BinaryReader(stream); byte[] result = reader.ReadBytes((int)stream.Length); reader.Close(); return result; } Do I need to lock the file because this method is called from worker threads? I mean, would reading the same file more than once at the same time cause problems? Tag: Assembly Trust Question Tag: 82179

    - Assembly Trust Question I have an executable I have built. On some computers it runs without a problem. On others it will give a security exception. If I run the .NET Configuration wizard and move the level from no trust to the first level up, it will then run the program. How can I workaround this or fix it? I can't find anything. Thank you.

    - 1.0 SP 3 & SecurityException I have an application which is a EXE running as an NT service. It accesses an assembly (a1) which in turn accesses types defined in another assembly (a2). All was fine before SP3. Once SP3 is installed, I'm getting SecurityException whenever a1 wants to access types in a2, getting "Request for permission of type xxx failed". Everything is installed local so they all have FullTrust. One more piece of information. The types in a2 are all enumeration if that makes any difference. I caught the SecurityException and examined it, but it didn't give me much information. The PermissionState property is empty and PermissionType is null. Anybody knows if this is something changed/broken in 1.0 SP 3?? Thanks a lot. Tag: Assembly Trust Question Tag: 82172

    - Net Framework 1.1 SP1/VS.NET 2003 SP Question When I do a windows update I noticed that the Net Framework 1.1 SP1 is available. The question I have is, does that mean that there is a SP available somewhere for Visual Studio.NET 2003? I would think that a SP for both would be required if there are changes to the Framework! I found several early articles on the internet which seem to support this belief; and stated that both the framework and 1.1 service pack were being coordinated with XP's SP2 rollout. However, since the early articles I have not been able to find anything on the Visual Studio.NET 2003 Service Packs! Any ideas? Thanks! Jim Tag: Assembly Trust Question Tag: 82169

    - FolderBrowserDialog does not display the directory structure after installing .NET Framework SP1 It only contains the buttons to create a new folder, Ok and Cancel. Is there any main thread where issues regarding to SP1 of the .NET Framework 1.1 are assembled? This is the second UI bug I found after installing the SP a few hours ago. If I find more, I would like to remove it, but I don't see an uninstall feature. Is it possible to remove SP1 or do I have to reinstall the framework from scratch?

    - Is AxImp broken in SP3? Hi, I'm experiencing problems with AxImp.exe since installing framework 1.0 service pack 3. When I try to run AxImp I get: AxImp Error: Invalid Primitive Type: System.Reflection.Missing. Only CLS compliant primitive types can be used. Consider using CodeObjectCreateExpression. If I run AxImp with the /source option I get: AxImp Error: The process cannot access the file "....cs" because it is being used by another process. The errors only occur for one of our OCXs, the others work fine. It definitely seems to be related to the service pack. If I reinstall the framework it works, but if I then install SP3 it breaks again. Is anyone else experiencing this problem? Is there a fix or workaround? Thanks, Al Tag: Assembly Trust Question Tag: 82153

    - Types vs. Attributes We want to be able to load the classes from a directory that derive from a particular base class. So the question is whether attributes for each deriving class will help us in finding these classes faster or not? We currently have attributes and use those, but it seems very slow to go through all the assemblies and try to get all of the attributes from there. I'm looking for a way to speed this up and wanted to know if anybody is doing something similar and had any pointers as far as speed. Lance Johnson Tag: Assembly Trust Question Tag: 82151

    - Access to installation files from Custom Actions class. Hi all, Is there a way to get the path to the temp directory where installation files are unpacked to? Also is there a way to specify in a deployment package that a file should not be installed anywhere but simply included into the package? E.g. I want to include install_docs.txt (as losely packaged) but it should not be copied to the destination dir during install? I tried setting "Exclude" to true but the file gets excluded from the deployment package completely. Thank you. -Oleg. Tag: Assembly Trust Question Tag: 82134

    - Reading data from a Socket I have coded a method which reads data from a socket in chunks of 2048 and concatenates those chunks into a string before returning the string to the caller. Almost all the time this code works perfectly well. Occasionally, for a reason I've yet to determine, the returned string seems to be truncated at 2920 characters. This causes problems in another part of my app because the string is Xml, which then fails to be loaded into an XmlDocument object. The code for the method is: Friend Shared Function ReadAllDataFromSocket(ByVal reciever As Socket) As String Const BUFFER_SIZE As Integer = 2048 Dim buffer(BUFFER_SIZE - 1) As Byte Dim bytesRead As Integer = BUFFER_SIZE Dim sTemp As StringBuilder = New StringBuilder(BUFFER_SIZE) Dim DataRead As String = Nothing ' Loop until all data has been read. While (bytesRead = BUFFER_SIZE) ' Read this chunk of data. bytesRead = reciever.Receive(buffer) ' Check that some data was read. If bytesRead > 0 Then ' Add this data to the string builder. DataRead = Encoding.UTF8.GetString(buffer, 0, bytesRead) sTemp = sTemp.Append(DataRead) End If End While ' Return the string to the caller. Return sTemp.ToString() End Function I tried recoding the method so that it reads the data all in one go, using the Available propery of the socket to determine the buffer size. However Available seems to be very unreliable and I've seen many people recommend avoiding it. Does anyone have any ideas as to why I get this problem, or can anyone suggest an alternative way of getting the data out of the socket? Thanks, Ross Tag: Assembly Trust Question Tag: 82125

    - Problems with XP style in Windows forms after installing .NET 1.1 SP1 Hi, after installing the SP1 for the .NET Framework 1.1, I have one Windows form that does not display the push buttons in XP style anymore. It worked without problems before and all other controls still have the XP look and feel. Just to make it sure, I verfied that the FlatStyle property is set to System and since yesterday the application looked great. Now it's poor because of a mix between the XP and the classic Windows style. I have other applications that still show the XP style buttons and I'm using the same technique in all applications (as described in KB830033, which so far worked perfectly in COM Addins and in native Windows applications too). Furthermore, I put the classes listed in KB830033 into an assembly that resides in the Global Assembly Cache, so I'm really using the same code in all applications. I don't see any reason why this single application does not display the XP buttons, but it definitely happened after installing SP1. I'm running Windows XP SP1 with all important hotfixes, but have not yet decided to install SP2. Does anyone encountered the same problem and may even have an idea how to fix it?

    - sqlserverCE sdf Hi Is there a way to generate a sdf -file on a PC, and move it for the SQLServerCE -device for usage there? I've got aprox 100 000 records to insert to the sdf -file, and have built a webservice for fetching chunks of records, inserting it to the sdf. This process takes hours. I guess overhead in Webservices to be the cause, and figure a TCP sollution would speed things up. However, doing all of this - serverside would be the quickest I'm sure. Using a pocketPC/winCE emulator on the server, generating sdf would do the trick I guess. But smells messy. Thanks, Finn Tag: Assembly Trust Question Tag: 82112

    - dll's in VSNET2003 Compact Framework not registered Hi, After reinsalling VSNET2003 to a new path on my harddrive, the dll's in the Compact Framework are nor re-registered. One of my coworkers experienced the same problem with uninstalling and thereafter installing VSNET2003 to a new path on the harddrive. It is the VSNET2003 installation that "forgets" to re-register the Compact Framework dll's to the new path. His only solution was reinstallation of winXP and thats not an option in my case. OS: Windows XP + SP1a + alle updates I have tried: - uninstallation of VS NET 2003 + manual clean up + installation again - repairs of VS NET 2003 - extern installation of NET Compact Framework 1.0 SP2 - gacutil - but couldnt locate the Compact Framework... - MS RegClean.exe to secure clean up after uninstallation. That provoked Bluemoon!! I cant spare much more time in investigating why this happens, and are quite new to VSNET. I still have Java though - that always works, but I liked the Visual Studio environment to develop in. Can anybody help? Michael Zakarias http://www.wmdata.dk Tag: Assembly Trust Question Tag: 82107

    - Question about Enumerations When I use enumerations I frequently get compilation errors that state: "Inconsistant Accessibility: <something> is less accessible than <something> I have been getting around this through casting but really don't like that since it defeats enumerations.

    - Max Length on ProcessStartInfo.Arguments I have noticed that when I try to run a process using ProcessStartInfo to set a really long argument, over 33,000 characters. The whole string doesn't get passed into the process being started. Specifically I am using the System.Diagnosis.Process class to run csc.exe and compile our software product because we have a solution with over 170 projects and it takes 40 minutes to load and build in visual studio. But by parsing the solution and project files I can build it in under 5 minutes with a custom written app. The only problem I have is a couple of projects have so many files in them now, when I create the compile string it cuts off the end of it before starting csc and so that specific project doesn't run. Does anyone have any thoughts on this? Thanks for the help. If you can email me back at jonathan.p.crawford@_TIGER_gmail.com minus the cat, I would appericate it.

    - Accessing POTS modem through framework? Is using an analog modem simply a dead art form or is there still functionality within the .NET Framework for accessing a modem on the computer, sending AT commands and sending/receiving character data? At a very minimum, I'd like to develop a small application that will dial a list of phone numbers from a phonebook and check the modem response strings to see if the call is answered or not.

Depending on what the user types into the textbx, I repopulate the grid, i.e. rebind new data to it. I would like not to have to include the following two lines in both Page_Load and in the event handler I wrote for the text box: OleDbConnection MyConnection = new OleDbConnection OleDbCommand MyCommand = new OleDbCommand(); I'm looking to broaden the scope of these declarations to cover both of the above situations, but don't quite know where to put the declarations.

    - Metafile problem I am having a problem using DrawImage to scale metafiles. Here is what I am doing: Metafile mapImage = new Metafile("C:\\image.wmf"); If I draw the entire metafile it draws correctly: g.DrawImage(mapImage, 0, 0); If I try to scale the metafile into the graphic, it does get scaled correctly but tho origin is moved so what gets drawn in position 0,0 is not position 0,0 in the metafile even though both rectangles have 0,0 values. g.DrawImage(bitmapMap, new Rectangle(0, 0, bitmapDest.Width, bitmapDest.Height), new Rectangle(0, 0, mapImage.Width, mapImage.Height), GraphicsUnit.Pixel); In fact the above statement SHOULD display the entire metafile but it only displays a portion on the lower right corener of the metafile.

Can I add a FileSystemWatcher or Timer objects into application dynamically? that's means i don't want to use <object runat="server" scope="application" ...... />. and i just want to use the dynamic methods just like Application["timer1"] = timerobject; to add the object into application and keep all of the events of the objects inside application can be fired up automatically in application behind-end. for example: *Global.asax <script language="C#" runat="server"> public void Application_OnStart(){ FileSystemWatcher watcher = new FileSystemWatcher(); Application.Add("watcher1", watcher); Application["watcher1"].Path = "D:\abc"; Application["watcher1"].NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName | NotifyFilters.Size; Application["watcher1"].Filter = "*.*"; Application["watcher1"].Changed += new FileSystemEventHandler(OnChanged); Application["watcher1"].Created += new FileSystemEventHandler(OnChanged); Application["watcher1"].Deleted += new FileSystemEventHandler(OnChanged); Application["watcher1"].EnableRaisingEvents = true; Application["watcher1"].BeginInit(); } private static void OnChanged(object source, FileSystemEventArgs e) { /* somethings which need to be done */ } public void Application_OnEnd(){ string[] appkeys = Application.Allkeys; foreach (string appkey in appkeys) { if (appkey.StartsWith("watcher")==true) { Application[appkey].EndInit(); Application[appkey].Dispose(); } } Application.RemoveAll(); } </script> *Addwatcher.aspx <script language="C#" runat="server"> pivate void Page_Load(){ FileSystemWatcher watcher = new FileSystemWatcher(); Application.Add("watcher2", watcher); Application["watcher2"].Path = "D:\webcustomer"; Application["watcher2"].NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName | NotifyFilters.Size; Application["watcher2"].Filter = "*.*"; Application["watcher2"].Changed += new FileSystemEventHandler(OnChanged); Application["watcher2"].Created += new FileSystemEventHandler(OnChanged); Application["watcher2"].Deleted += new FileSystemEventHandler(OnChanged); Application["watcher2"].EnableRaisingEvents = true; Application["watcher2"].BeginInit(); } private static void OnChanged(object source, FileSystemEventArgs e) { /* somethings which need to be done */ } </script> *Delwatcher.aspx <script language="C#" runat="server"> pivate void Page_Load(){ Application["watcher1"].EndInit(); Application["watcher1"].Dispose(); Application.Remove("watcher1"); } </script> Can i do like this? and will it be work?

    - Resource Sharing I have noticed that successive calls to ResourceManager.GetObject with the same paramters return references to different objects. This is fine when a resource is only being used once (at a time) or when an application intends to edit the returned object at runtime (and each resource consumer needs it's own copy to edit). Unfortunatly, this is a major problem when you need to share resources. For example, I would like to use embedded resources for textures of objects in my C# based 3D engine. If several objects use the same geometry, textures or other resource, they should all share a reference to the same resource object. Is there functionality in the .NET framework for shared resources? If not, is my only option to code my own SharedResourceManager class? Thanks, Brandon Bloom Tag: Assembly Trust Question Tag: 82023

    - CryptProtectData key. Hi all, I'm considering to use the Data Protection API CryptProtectData, with the flag set for CRYPTPROTECT_LOCAL_MACHINE. The documentation says this "associates the data encrypted with the current computer instead of with an individual user". On what computer characteristics is the secret key (?) based then? What computer modification may break it? Or is it possible to obtain the same key on another computer somehow (reasonably mimiced hardware, with a ghosted OS perhaps?)

    - Form deserialization Hi, i'm working in a form generation tool=2E I've got a base class= TpForm to build all the windows in the application and now i= want to be able to design subforms, but the problem is that= these subforms are downloaded by reflection from different= repositories in design and run-time; so, what i've done is build= a custom TpFormSerializer that replace the codeDOM object= creation expresion in InitializeComponent(), and attachi it to= TpForm class=2E For example, if i have the line this=2ESUBV194i1 =3D new= Fujitsu=2ETpnet=2EUser=2EInterface=2EWin=2ESUBV194i1() this would be replaced with this=2ESUBV194i1 =3D AddSubForm("SUBV194i1", "SUBV194i1"); and i also change the subform declaration statement, so subform= type dependence is not neccesary in the designer project, in= this way: private Fujitsu=2ETpnet=2EUser=2EInterface=2EWin=2ESUBV194I1= SUBV194i1; with private TpForm SUBV194i1; The problem is that in the deserialize method i simply invoke the= base serialization manager and it seems that the IDesignerHost's= CreateComponent method is not able to create the subform at= startup, am i missing something?

    - ANN: NLog - a .NET Togging Tool v0.2 beta 1 has been released NLog 0.2-beta1 has been released and can be downloaded at: http://nlog.sourceforge.net/. NLog is a .NET logging library similar in concepts to log4net, designed with simplicity and flexibility in mind. It supports the base concepts of log4net (appenders, layouts, filters) and makes them easy to use in your application. Features: - ease of use (uses familiar WriteLine() style interface) - maintainability (trivial to configure and re-configure) - speed (uses "zero allocations" principle whenever possible), no-logging situations are detected really quickly - binary portability (.NET, Mono, .NET CF) - use a 'portable dll' or a 'compact dll' - not over-patterned - it just does logging - easy to migrate from log4net If you find log4net too difficult to configure and use effectively or simply too java-ish then NLog might be the tool for you. It's open source released under BSD license. See http://nlog.sf.net/ for more information.

I have an executable I have built. On some computers it runs without
a problem. On others it will give a security exception. If I run the
.NET Configuration wizard and move the level from no trust to the
first level up, it will then run the program.

How can I workaround this or fix it? I can't find anything.

Thank you.
