 - ClickOnce Deployment and the ConfigurationSection I have created an application that stores my configuration settings using the ConfigurationSection, ConfigurationElements, and ConfigurationElementCollection. Due to the complexity of my configuration (hence the collection piece) I did not try using the settings API. I have now gotten to the point where I need to worry about deployment and updates. ClickOnce deployment works great except for the fact that everytime my application gets updated, the settings will get lost. Is there a way to use ConfigurationSection along with ClickOnce and get the settings transferred on an update? Or do I need to investigate another method of updating or store my settings in another manner? TIA Seth Tag: Directory Structure to XML DOM? Tag: 123303

 - Suppressing .Net-BroadcastEventWindow issue Since migrating an application from .Net framework 1.1 to 2.0, I have an issue where when the app exits, I receive a popup error referring to the .Net-BroadcastEventWindow having an application error. Some searching through Google groups indicates that this is probably COM related. The app does in fact reference a legacy COM object (not ours to control) and if I don't access it, the error doesn't occur on exit. Unfortunately, that COM object is rather important, so I can't choose to not use it. Ultimately the app seems to work fine and without any errors relating to the COM object, and as mentioned, none of these issues existed in the 1.1 framework. At this point I'd just like to suppress the error if at all possible. Finding the cause is a good goal going forward, but I think this error is more aesthetic than consequential. Any suggestions?

 - monitor.tryenter I am using monitor.tryenter as follows Do Until Monitor.TryEnter(lockLastBets, 10) moni += 1 sendMsg("PMB std" & Thread.CurrentThread.Name & " failed " & moni & " times", timesOther) Loop It appears that (occasionally?) the tryEnter doesn't relinquish control to the other thread which is holding the lock. I thought the whole point of TryEnter was to give a chance for the other lock holder to finish his job and release the lock. After n failures TryEnter returns to caller returning false. The caller can then decide what to do. I send an error msg and go round the loop again. Have I got it wrong? -- -- Victor Tag: Directory Structure to XML DOM? Tag: 123285

 - Reflection, Enums and their values? I have an set of enums like the following, that are in a class that I'm using from elsewhere; Public Enum Q001resp As Integer Yes = 1 No = 5 NotAnswered = 0 End Enum Using Reflection, I am able to look at the properties of that class, and I'd like to be able to not only get the names of these enums, but also their possible values. For instance, I think I can get the Q001resp name (if I recall, I've done this before, but can't say for sure). I'd like to be able to get the string of "Yes" and the value of 1, the string of "no" and the value of 5, and the "NotAnswered" and value of 0. Is this possible with reflection?

 - Weird impersonation issue Just recently, we started getting a weird impersonation problem on one of our web apps (which used to work). IIS is set to use Windows Authentication, Anonymous is disabled Web.config specifies to use Windows Authentication, Impersonate = true Web server is trusted for delegation. The app goes out to a file server (on the local network) to retrieve an image file. Here is where it gets weird - If I run the app from my machine, the authentication and impersonation work and I can get the file to manipulate it. If I go to the Security Log on the file server, I can see my User Name and the Success Audit. However, if I go to any other computer, still using the same domain account, the Impersonation does not seem to make it all the way to the file server. I use System.Security.Principal.WindowsIdentity.GetCurrent().Name to get the user that the process is running under and it returns my user name, however, on the file server, there is a failure audit from WEBSERVER\Anonymous Logon. I have had another person test it, and they get the same results - it does not work from their machine, but if they log on to my computer, it works fine. Anyone have any idea what is going on here? Why is this only working from my computer? I thought I looked at all the relevant settings in IE, etc, but can't find any differences. Any ideas? Tag: Directory Structure to XML DOM? Tag: 123279

 - WSUS Hi, Please, we would like to know some specific information related to the new Windows Server Update Services 3.0. We know that there is a method in IUpdateServer, GetPublisher which gets the IPublisher interface. The GetPublisher method takes a string parameter sdpfile. We would like to know what data we need to pass to this API to get an IPublisher interface. IUpdateServer wsusServer = AdminProxy.GetUpdateServer(); IPublisher publisher = wsusServer.GetPublisher(sdpFile); // Need information on sdp file, that we need to provide publisher.PublishPackage (sourcePath, packageDirectoryName); // Need more information on sourcePath , packageDirectoryName parameters More over us are looking for more information on the PublishPackage method of IPublisher interface. Right now the issues that we face are there is not much documentation around in the MSDN. Can you please help us by your thoughts and some samples to start with?

 - Overriding Equals method hi, I have some questions regarding overriding Equals method so I can use it on my objects. 1) When overriding Equals method, do I have to check all fields for "equality" or just the ones I want to use to distinct my objects ? As far as I know, only the ones I want to use to distinct my object by ... field "Name" in the example bellow. 2) What does a method GetHashCode() do exactly, and do I have to put all of my fields in it or just fields I want to use to distinct my objects by ? Thanx, Neven --------------------- public class Person { string _Name = ""; string _Phone = ""; public string Name { get {return _Name;} set {_Name = value;} } public string Phone { get {return _Phone;} set {_Phone = value;} } public override bool Equals(Object obj) { if (obj == null || GetType() != obj.GetType()) return false; Person person = (Person)obj; return _Name == person.Name && _Phone == person.Phone; } public override int GetHashCode() { return _Name.GetHashCode() ^ _Phone.GetHashCode(); } } Tag: Directory Structure to XML DOM?

 - CLR Debugger points to incorrect source code I have two programs with the same name but different name spaces. i.e . BusinessProcess.Provider and DataAccess.Provider What happens when I debug remotely, is that the debugger will point to the BusinessProcess.Provider instead of the DataAccess.Provider. I can tell that its really executing DataAccess.Provider because of the line numbers and the variables change values as if its executing DataAccess.Provider. But, its still pointing to BusinessProcess.Provider while debugging. Anyone know how to make the CLR debugger point to the correct namespace.program? Tag: Directory Structure to XML DOM? Tag: 123244

 - comparison reporting -- technique suggestions? hello, i have been given a challenging project at my org. i work on an inventory management web application -- keeping tracking of parts assigned to projects. in the past, i built an in-house ASP.NET reporting system. just your standard stuff -- user clicks on a report, the page executes a pre-defined SQL query, a dataset is formed and bound to a data repeater. that works well for us. and using some nifty CSS, my reports look good on screen & on paper. now, however, my users would like....comparison reports. with comparison reporting, theyd like the ability to: a) take a "snapshot" of a given live report, storing it for later b) compare a given report to one of the previously-stored snapshots the mechanism for this would ideally show them a screen of three sets of data: - new rows (parts added since the referenced snapshot) - deleted rows (parts that existed in the snapshot, but dont now) - changed rows (parts that existed in the snapshot, but have at least one different column) ideally, theyd like a technique that can be used generically for any of our current or future reports (but limited, of course, to same-report-type comparisons). ...some tall order -- this is nothing ive ever attempted before. a few ideas came to mind for doing this: 1) when a user takes a snapshot, the dataset is serialized into text, and dumped into a CLOB in the db. when the user later does a comparison, the desired CLOB is restored into a dataset. then code must be written to enumerate and evaluate the tables. rows matching one of the categories must be inserted into new a "results" dataset (consisting of the 3 tables for new/deleted/changed rows). 2) alternatively, some sort of "history" could be implemented on our tables on the (Oracle) backend -- like triggers that update new history tables, that log changes. then some means of comparing present-day data to the history tables must be devised. 3) investigate a 3rd-party reporting package that offers this ability. as i mentioned, ive never set about this particular task in my years of .net web apps. no idea on how it can or should be done. can anyone point me to references, or suggest possible solutions? thanks! matt Tag: Directory Structure to XML DOM?

 - Problem with using AppDomain/Assembly Loading in Queued Component Hi, After many searches online and cannot find the right solution for my issue, I decided to post my question here. If you can help or know something on this, please give me some hints? Thanks in advance ! ISSUE: I have a queued component ( COM+ serviced component and written in C#) that needs to load my .NET assembly dynamically into the AppDomain. Code goes like this: AppDomain newAppDomain = new AppDomain (); newAppDomain.CreateInstanceAndUnwrap("myClassName","myProjectNameSpace.myClass"); *** Note: myClass assembly is C# and I generated tlb for it and loaded the assembly into GAC and registry (via regasm). *** When running this queued component, I always got error "System.IO.FileNotFoundException: File or assembly name myClassName, or one of its dependencies, was not found." Looks like DLLHOST is looking into C:\WINDOWS\system32\ for my dll while my dll is actually in another directory (Note: the dll of queued component and my assembly are in same bin directory). What needs to be done to avoid this error ? Some error log: System.IO.FileNotFoundException: File or assembly name myClassName, or one of its dependencies, was not found.

It runs fine from the server but from the workstation it generates an error message something like "This program could not start because the program configuration is wrong.

 - WSE910 and 'Root element is missing.' I am having trouble with WSE3 and domain authentication\authorisation for a web service. When using a the 'NETWORK SERVICE' account for the application pool in IIS 6.0 the web service work perfectly correctly, we are able to call the web service end point and we can authenticate through our custom WSE authentication token manager, but when we switch over to a domain service account we have created to run the application pool we get the following error: 'WSE910: An error happened during the processing of a response message, and you can find the error in the inner exception. You can also find the response message in the Response property.' The inner exception states: 'Root element is missing.' The domain account is a member of the IIS work process group on the local box, it as the required security permissions for the directory where the web service is installed. What is very strange is that when this service account was made a domain admin temporarily the call worked perfectly fine. So the question is what permissions does WSE3 require so that we can get our domain service account to work correctly. Cheers in advanced Ollie Riches Tag: Directory Structure to XML DOM? Tag: 123215

 - css failure on postback Hello all, I develop aspx pages for internal use. We use IIS 6, .net 2 and IE 6. In the head of the clientcode I call a css file like "@import url(../CSS/Styles.css);" All this runs fine. When I pubish the site to the server and call it from a clientmachine everything looks fine as well. But when there is a postback all styles are gone and the site is nearby unuseable. On the next postback it mostly looks fine again. Do I use the wrong way to implement the css or do I have to update the .net Framework with something? Thanks for help.

 - C# to C++ port Hi everyone, We have a dll component developed in C# and used by the other projects (exe) written in C#. This component has been tested and proved to be very robust component and so we are going to re-use it in another application (very large code base) which has been already written in unmanaged C++. What is the best strategy between the following two options: 1. Write a managed C++ wrapper around the C# component and use that wrapper in our unmanaged C++ project. 2. Port the C# component completely to an unmanaged C++ component and then use it in our unmanaged C++ project. The main advantage of option 1 is that it seems much quicker and we can also benefit from .Net framework library without having to re invent the wheel or use other 3rd party libraries. The main advantage of option 2 is that we are not going to get involved in the potential problems involved in mixing managed and unmanaged codes. Does anyone have any other ideas (maybe option 3 ...) or see another pros and cons in going with either option 1 or option 2? Any help would be appreciated Luca. Tag: Directory Structure to XML DOM?

 - acquiring standard out, standard error Hi, I have managed to acquire the standard out & error streams of an app by starting it with System.Diagnostics.Process. Works great. How do I acquire the standard output & error & in streams of an already running application, for instance, a service. Basically I need to monitor the standard out & error streams of a running app from another app. Thanks Paul Tag: Directory Structure to XML DOM? Tag: 123156

 - Target the Framework version from 2.0 to 1.1 Dear all, I have encountered a problem of "DragDrop registration failed" problem in my .NET 1.1 dll because of the assembly binding is always going to .NET 2.0. Therefore I tried to specifiy the runtime version and redirect those bindings in MyModule.dll.config. The binded assemblies, however, are still in .NET 2.0, according to both VS.NET 2003's output log and VS.NET 2005's fuslogvw. Meanwhile, they also logged compiling and linking processes. At that stage, linked assemblies are in version 1.1 correctly. My question is, does it means that configurations of runtime version and assembly binding redirection do not work backward from 2.0 to 1.1? Thank you for your precious time.

 - Problem with transprancy and opacity When I give my form a white background, make the transparency key white, and have the opacity set to 100% (1) everything works fine. However, if I change the opacity to 50% (.5) the rather then have a form that is transparent where the white is I get a foggy white. Is there a fix for this, I want the form to be 50% opacity and the transparency to remain fully transparent. Thanks, Rob Tag: Directory Structure to XML DOM? Tag: 123135

 - vb.net not responding Thanks in advance for any help. I have a Windows form I have written in vb.net (2003 - Standard Ed.). It reads an xml file, populates a datagrid and updates back to the xml file when changes are mde on the datagrid such as additions or record modifications. I go to build with F5 and the hourglass pops up and doesn't go away even though the Windows Task Manager doesn't show "Not Responding". The build is listed as 1 Successful buildwith no erros. Any ideas on this one? Here is my code: Imports System.Data Imports System.Xml Public Class Form1 Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " #End Region Dim xdd As XmlDataDocument Dim ds As DataSet Private Sub btnLoadXml_Click(ByVal sender As System.Object, ByVal e As _ System.EventArgs) Handles btnLoadXml.Click Dim xtr As XmlTextReader = _ New XmlTextReader("C:\Documents and Settings\Cheryl&Brian\Desktop\XMLforProject.xml") xdd = New XmlDataDocument ds = xdd.DataSet() ds.ReadXmlSchema(xtr) xtr.Close() xtr = New XmlTextReader("C:\Documents and Settings\Cheryl&Brian\Desktop\Books.xml") xtr.WhitespaceHandling = WhitespaceHandling.None xdd.Load(xtr) dgXML.DataSource = ds dgXML.DataMember = "Book" xtr.Close() End Sub Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As _ System.EventArgs) Handles btnSave.Click Dim xtw As XmlTextWriter = New XmlTextWriter("C:\Documents and Settings\Cheryl&Brian\Desktop\XMLforProject.xml", System.Text.Encoding.UTF8) xtw.Formatting = Formatting.Indented xdd.WriteTo(xtw) xtw.Close() MessageBox.Show("The XML file has been successfully updated !")

 - What framework is running in this scenario? I have a VB6 application that references a few .Net 1.1 components, and one 2.0 component. Does that mean that all will be running under 2.0? Is there any way to force the 1.1 pieces to run under 1.1, and the 2.0 to run under 2.0? I know about setting a config file to force a certain framework, but I think that is only good for the entire application. Thanks Tag: Directory Structure to XML DOM? Tag: 123124

 - ClickOnce Nightmares I'm trying to deploy a clickonce application using the command line (so that I can have it in a batch process). I have the following problems/questions. Please, if anyone can help, I'd appreciate it. I've managed to deploy the application using the instructions by microsoft, here: http://msdn2.microsoft.com/en-us/library/xc3tc5xx.aspx This is all peachy keen. Works fine except... 1 - There is no "setup.exe" file as occurs when deploying through the IDE. Why is this and can I get one? 2 - It cannot deploy over the network. Only locally (in other words, installing from \\mycomputer\public fails, but c:\public succeeds). 3 - When it is installed it doesn't give me an icon in the "Start\Programs" menu nor is it listed in the "Add/Remove Programs" when installed. I was wondering, somewhat, if it actually installed at all except that on install it runs (as it has been instructed to do) and the exe is installed in my user directory. Please help. What am I missing? If you have any questions feel free to ask. I need to get this out the door soon so I will be checking this post regularly. tia, rts. Tag: Directory Structure to XML DOM?

 - HttpWebRequest ThreadPool usage - strange behaviour I posted this at dotnet.general a few days ago, but as far as there was no answer, I'll repost it here. I you think that there is even more appropriate group for this, please let me know, and I'll repost. Thanks. <Repost> Hi, I read a lot of articles about deadlocks and ThreadPool overloading when a lot of WebService or WebRequests are made from and ASP.NET applications. In most of these articles and examples there is a statement, that HttpWebRequest.GetResponse() call is always executed asyncronously in v. 1.x of the network. I used Reflector to examine this, and indeed, the code looks like: BeginGetRequest(...); ...... EndGetRequest(); Now, I created a test console application, which invokes a simple web service. This service only invokes Thread.Sleep for the number of seconds passed as parameter. Note - this is for .Net v.1.1 SP1. My test application starts 3 threads (not from the threadpool). The first one prints on console the current ThreadPool free threads. And the other 2 make invocation of the sample web service (not using a proxy, but pure GET request, using HttpWebRequest class), requesting delays of 10 and 20 seconds. Now, the strange thing is, that I do not see any thread of the ThreadPool used while waiting for the HttpResponse, I.e. this behaves very differently from what I read so far about how HttpRequests are made. I tried to invoke HttpWebRequest in 3 different ways (just comment and uncomment the corresponding 2 lines in the Main method): 1. A custom thread just invokes the synchronous GetResponse method - no threadpool usage is visible, even as per the articles I mentioned, it should translate in async invocation internally. 2. A threadpool thread invokes synchronous GetResponse - then obviously a threads from the pool are used, but only the ones, which make the call, but still not visible another threadpool thread which is used by the GetResponse. 3. A custom thread, which invokes async GetResponse (with BeginGetResponse/EndGetResponse), as well as async reading of the response stream. Still I can not see a threadpool thread to be used. Can somebody explain this behaviour? Why this sample works not like it should be? If all these articles are wrong, should I worry if I have a async web service, which internally invokes a 100-200 HttpRequests per invocation. I may have more than 300 invocations of that service in the same time? Actually, what I'm after is a web service, which will be used by more than 300 clients at the same time, which by itself retrieves 100-200 web pages per request. I want to speedup the process, and to use all available resources to fetch as many pages as possible at a time using threads. At the following URL you can find a zip with the source files I used. You need to set your IIS virtual directory to map to the test web service: http://216.17.90.93/ThreadTest.zip These are the articles I read on the topic: <http://msdn.microsoft.com/msdnmag/issues/04/12/NETMatters/> <http://www.deez.info/sengelha/blog/2005/03/03/beware-threadpools-and- httpwebrequest/> <http://msdn.microsoft.com/library/default.asp?url=/library/en- us/dnservice/html/service07222003.asp> <http://msdn.microsoft.com/msdnmag/issues/03/06/Threading/> Cheers Sunny Tag: Directory Structure to XML DOM?

 - Content-Type of MailMessage Why can't we change the content-type setting of a System.Net.Mail.MailMessage? We can change this value for Attachments, but not for the message itself... It's the only thing that prevents me from creating signed/encrypted messages... I can sign the message, add the smime.p7s but I can't change the message content type to multipart/signed... And adding the header doesn't help, the SmtpClient adding a Content-Type automatically... In fact, if the MailMessage would contain the same header properties (Content-xyz) as the Attachment, it would give a lot of flexibility... As for backward compatibility, not setting them would leave the default on, yes? In the meantime, I'll have to try another workaround: put the encrypted/signed message in an attachment...

 - How to get the domain name from a WinForm UserControl hosted in Internet Explorer I have developed a User Control (in .NET 2.0) that runs hosted inside Internet Explorer. like in these articles http://msdn.microsoft.com/msdnmag/issues/02/01/UserCtrl/ http://support.microsoft.com/?kbid=892466 Is there an easy way to reference the HTML Document "parent" of this control and ask it for the domain? I could not find any way to reference the document that worked (ex Parent or Container property) Is there a way to ask the IEHost.dll that is hosting this control in IE? Is there a way through the security model to ask the Assembly if it has been loaded with restricted permissions and if so why? and somehow get to the domain it was pulled down from.... Any ideas?

 - Some or all identity references could not be translated I get and error â??Some or all identity references could not be translatedâ?? when executes the code System.Security.Principal.SecurityIdentifier.Translate. It appears this happens to users that have been logged in for a long time. It appears our users are in the habit of not logging out for long periods of time. If the user logs out and then back in the error no longer occurs. Does any one have any idea what is happening here? Is the some AD setting that causes tokens to expire after some period of time?

 - Strange Performance Counter performance problem in Windows Service application Hello All, I experience a strange problem I do not how to approach. My windows service application uses several performance counter. Before when staring the service deletes category and attempts to recreate it. *If* the category previously existed and has been deleted prior to recreation an attempt to create a counter causes Service Manager timeout after 30 sec. So, category gets deleted, but it can not be recreated. I modified my service so it deletes category upon termination, but then it fails during the restart while checking if the category exists. It is completely weird. Now, the really strange part: the same code executed as a console application with *the same security credentials* executes momentarily. Sample code attached below. The code uses .Net 2.0 methods but the same issue can be seen in .Net 1.1. Did anyone experience a similar issue? Is there any known solution? Thank you, Tomasz Const ThisServiceName As String = "My Service" Trace.WriteLine("Checking performance counters category.") If PerformanceCounterCategory.Exists(ThisServiceName) Then Trace.WriteLine("Deleting performance counters.") PerformanceCounterCategory.Delete(ThisServiceName) Trace.WriteLine("Performance counters deleted.") End If WriteToLog("Creating performance counters.") PerformanceCounterCategory.Create(ThisServiceName, "", PerformanceCounterCategoryType.MultiInstance, "test counter", "") WriteToLog("Performance counters created.")

 - Exception profiling? I need to be able to see what exceptions are being raised by an ASP.NET application. I can see from perfmon that our ASP.NET app is throwing hundreds, if not thousands, of exceptions per second but very little is being logged. So what I'd like to do is run a profiler and see exactly what exceptions are being raised and where they are being raised. I've seen several profilers, but all seem to be just heap and/or memory profilers. I haven't found one that will show me exceptions. Does such a tool exist? I know that there is a Profiler API, but I'd rather not dive into writing my own for this one project. Thanks in advance! Tag: Directory Structure to XML DOM? Tag: 123111
