    - Best practice for single instance and file associations? What is the best practice for a (.Net 2.0) application that is limited to a single instance and has file associations? There appear to be two methods for communicating verbs between Explorer and an application: command line and DDE. Going w/ the command line route, if there is already an instance of my application running, I need to detect that, and then communicate the command line to the 'main' instance using ? Remoting, I guess? Using the DDE route: this seems like the more standard route, however I'm not seeing anything that immediately supports this in the .Net Framework. ? There has to be something, as this is Windows standard behavior since when... Anyone have any thoughts/comments/pointers/suggestions on what is best/standard practice for handling file association verb requests in .Net? Thanks!

    - Using CSharpCodeProvider to create MANY assemblies I am planning to use the CSharpCodeProvider to generate some compiled functions in my app. In my current implementation, All of these functions are generated in one swipe... thus they all invoke the compiler once, and create only one DLL. My new requirement tells me that I need to be more dynamic... that I can't queue up all of these functions... I actually need to do them more on demand. The number of times this happens can be as many as 10,000 times... each with a different calculation. This would mean that I invoke the compiler 10,000 times and create 10,000 in-memory DLLs. This idea scares me... can .NET handle that many DLLs being linked to the app? Does anyone know about the performance overhead of such an endeavor? I am about to write some tests to gather data, but I was wondering if anyone out there has experience with this type of execution. Am I going to run into performance penalties for invoking the compiler that many times? Am I going to run into performance penalties for having that many DLLs in the app domain? If so, are there any workarounds that anyone knows of?

    - Response.TransmitFile - Windows Mobile 6 Hi, I have use the following code to transmit a file back to the browser that worked fine on a HTC_TTyN device running windows mobile 5.0. The code executes in the onclick event of a mobilelist control. Now on a similar device running window mobile 6.0 the file is not displayed - the link causes a post back succesfully and the code appears to execute - on the browser a bar is displayed breifely at the bottom of the window (although ist show 0KB to the right of the bar.) - seaming to indciate that a file is being transferred but the file save option (or the file) does not appear. Does any one have any ideas why this is not working ? I suspect it may be something that is specific to the HCT_TTyn devcie as we have identifed a separate issue where the browser capabilities where not being detected correctly - this was due to the fact that the useragent string was being prefixed with 'HCT_TTyn ' - to work around this we have defined a new htctty.browser file and registered it with asp.net which seams to have solved all the problems we were having - apart from this file transfer issue. protected bool SendFile(string filePath) { string fileName = System.IO.Path.GetFileName(filePath); if ((fileName != "") && (System.IO.File.Exists(filePath))) { try { Response.Clear(); Response.ClearHeaders(); Response.ClearContent(); Response.ContentType = "application/octet-stream"; Response.AddHeader("content-disposition", @"attachment; filename=""" + fileName + @""""); Response.AddHeader("content-length", new System.IO.FileInfo(filePath).Length.ToString()); Response.TransmitFile(filePath); Response.Flush(); Response.End(); Response.Close(); return true; } catch { return false; } } else return false; } Tag: is there any speed difference between a TVF CLR that returns an array vs yield as each result is ready? e.g. does returning the array all at once cause sql server to allocate more efficiently?

    - Assembly version detecting utility? Hi: Can anyone suggest an utility to detect specific assembly versions that are required by an exe? I find that, sometimes, I update some assemblies in the GAC and forget to update the client installation. When I execute the new exe file it unceremoniously exits. I then start looking at the assemblies in the GAC for different versions. It would be nice to have a utility that read the expected versions from my exe and report if any where missing. Does such a utility exist? TIA, Martin.

    - problem with var in 3.5 Hello, i don't know whether you can answer to questions about issues in 3.5, but i'll ask anyway. i have this code: var material = from materials in myDC.Materials where materials.Name == materialName select materials; it is supposed to load 1 object. how do i know if "material" is loaded or is null or smth like this? or should i use foreach every time? because in this case, material is IQueriable<Material>. or i can write an extension method, but i have to write this for all my domain objects... so, how can i do it in a simpler way?

    - Handling OOMs in new AppDomain Currently, I'm playing with some ideas on recycling application components for a service application when the individual parts die, because of an OOM. As a start to this I created a secondary AppDomain and created an instance of a class in that application domain that throws an OutOfMemoryException on an interval. I hooked up the AppDomain.UnhandledException event, but it isn't getting called. I can watch the output that says, "A first chance exception of type 'System.OutOfMemoryException' occurred in ..." But, nothing happens and the class seems to continue on its merry way. The error is thrown by an event handler (handling the Timer.Elapsed event). What is the proper way to handle exceptions in this context?

    - Process dump for later debugging Hi everybody. We are currently discussing the possibilities in our company, how to optimize the customer support for lots of our business customers. Since our new software products are based aproximatly by 80% on the dotNet-Framework, this seems to be the starting point. I was thinking about dumping a process in some state (the state at which some hard trackable error occurs) and sending this dump file to our support team for debugging reasons, but coud not find any functions/methods in the documentation to accomplish this. So my question would be: Is there a way to dump a .net based process at some state, for later debugging? And if there is, where would be the starting point to read about it - and - is there a way to load this file into a debugger, not connected to the machine where the dump file was generated? I remember the good old days in C/C++, where this was possible but after some research around the web, I did not find any answers for archiving this in C#.

    - New async socket behavior? Hi all, My company has recently migrated an application from .Net 1.1 to .Net 2.0. It uses the Socket class to perform some network communications. When Calling the BeginConnect() method, I have noticed that sometimes the specified AsyncCallback method will actually get called from the same thread as the BeginConnect() call was made from, prior to the the BeginConnect() call returning (i.e. same thread, same call stack). In .Net 1.1, the callback was always performed on a separate thread. I've even gone back and run some tests to verify this. I guess I would just like some confirmation. Did this behavior change between version 1.1 and 2.0? Is this a bug in .Net 2.0? The documentation for BeginConnect() explicitly states "the system will use a separate thread to execute the specified callback method." This caused an issue in our application that we were able to easily correct, but I wanted to throw this out there in case anyone else is experiencing a similar problem.

    - Timeout in HttpWebRequest.GetResponse() for large uploads I'm using HttpWebRequest in .NET 1.1 to post data files to a web server. The data files can potentially be 20mb or more. The relevant code for this looks essentially like: Stream reqStream = request.GetRequestStream(); reqStream.Write(data, 0, data.Length); reqStream.Close(); WebResponse response = request.GetResponse(); My problem is that GetResponse() times out while the file is being uploaded. My call to Write() is returning immediately rather than blocking until the data gets sent to the remote server. I know I can increase the timeout interval but that just pushes out the upper size limit for data without fixing the real issue. I've found that if I upload in pieces instead of writing the data all at once then every call to Write after the first one seems to block while data from the previous write gets uploaded. That potentially solves my problem since only the last, small piece will be left when I call GetResponse. I can't find any documentation confirming this behavior, though. Is there any guarantee that if I upload in pieces then my program can more or less monitor the actual transfer progress. If not, does anyone have other ideas how I can avoid calling GetResponse() until the upload is finished? Thanks, Ravi.

    - IIS7 and .NET 3.5 Hi, I installed Visual Studio 2008 Express earlier today, but I am not sure that IIS7 has been correctly configured to be able to use the 3.5 Framework. When I look at the AppPools listed in IIS7, I see two AppPools that are both set to use v2.0, and when attempting to create a new one, v3.5 simply isn't shown as an available Framework. Am I missing something (ie. the plot!), or is this just how it is?

    - VS2008 / Wpf - Designer does not show ListView correctly Hello, because there are no managed news group for window presentation foundation and one has told me I can use this, here my problem: I am now working with VS 2008 final Try the following code in VS2008 final (not beta 2 !!!) <Window x:Class="TestApp01.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:a="clr-namespace:TestApp01" Title="Window1" Height="300" Width="300"> <Grid> <ListView Background="Beige" Margin="34,51,60,68" Name="listView1"> <ListView.View> <GridView> <GridViewColumn Header="aaaaaa" Width="100" > </GridViewColumn> <GridViewColumn Width="100" Header="bbbb" > </GridViewColumn> </GridView> </ListView.View> </ListView> </Grid> </Window> When you run the program you see the columns of the listview. In designer you see nothing. Remark: In VS2008 beta2 this was no problem. Thank you for any help.

    - Source Debugging with VS2008 Anyone gotten this working yet? I'm really looking forward to stepping right into the Framework code.... I have it set to download symbols from: http://source.msdn.microsoft.com/symbols I got his link from Scott's blog at: http://weblogs.asp.net/scottgu/archive/2007/10/03/releasing-the-source-code-for-the-net-framework-libraries.aspx Unfortunatly, that link doesn't seem to exist. Visual Studio isn't able to download anything from there, and I don't anything when I point a browser at the address. I've tried also using the classic symbol server: http://msdl.microsoft.com/download/symbols ... but to no avail. I get symbols, but no source code. I do have the "Enable just my code" turned off (tried it both ways). I would love to hear from someone who got this working... -- Chris Mullins Tag: is there any speed difference between a TVF CLR that returns an array vs yield as each result is ready? e.g. does returning the array all at once cause sql server to allocate more efficiently?

    - Custom Configuration Section Help Hi everyone, I have created a custom configuration section which contains an optional configuration element. When I retrieve the custom configuration section, I also get an instance of the nested configuration element even when I don't have it inside the custom configuration section. Need help figuring out how to have null value for the optional configuration element when it is not in the configuration section. I have no problem retrieving the section: <customConfig> <customElement value="blah"/>  </customConfig> Would like to have null when I call customerConfig.customElement with the following config: <customConfig> </customConfig> Currently, calling customerConfig.customElement returns an instance of customElement with the attribute value="". Any help will be appreciated.

    - Q: displaying image in WPF I am probably doing something really stupid, but I cannot get an image to display in a window using WPF. I copied the image into my main project directory in Visual Studio 2005. I added the appropriate lines to my XAML file: <Image DockPanel.Dock="Top" Margin="5" Source="myimage.png" /> The image displays fine in the design view, but when I build the project and run it, the image does not show. Other controls move to fill the space where the image should be. Any ideas?

    - How to Serialize XS:DOCUMENTATION Id like to know if .NET XmlSerializer can to serialize comments to "xs:documentation". For example, consider the following code fragment written in C#: public class class1 : WebService { public struct SampleStructure { [XmlElement("NAME1")] public string S1; [XmlElement("NAME2")] public string S2; } [WebMethod] public Dataset SampleMethod ( [XmlElement("NAME3")] SampleStructure request ) { ..... } .... } I would like that the following serialized WSDL (only desired fragnment shown): ..... <s:complexType name="NAME3"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="NAME1" type="s:string" > <s:annotation> <xs:documentation>Commentes Here</xs:documentation> </s:annotation> </s:element> <s:element minOccurs="0" maxOccurs="1" name="NAME2" type="s:string" /> </s:sequence> </s:complexType> ..... So, is there anything I could place on the C# code to have the xs:documentation serialized?

    - AsyncOperation not working as I expected Hi, I'm trying to use AsyncOperation to execute a method in a main thread context from a worker thread. If I run the program from a console application then it doesn't work. If however I run it from a WindowsForms application it does. Basically I set the name of the main thread to "Main Thread", when the "ShouldBeInMainThreadCall" is called the Thread.CurrentThread.Name is null. However if I run it in a WindowsForms application it has the correct name. Could anyone help me with this? Find below the source for the console app: using System; using System.Threading; using System.ComponentModel; namespace TestThreadAffinityEvents { class Program { private static AsyncOperation operation; private static void DoWork() { operation.Post( new SendOrPostCallback( delegate( object state ) { ShouldBeInMainThreadCall(); } ), null ); operation.OperationCompleted(); } static void Main( string[] args ) { Thread.CurrentThread.Name = "Main thread"; Thread workerThread = new Thread( new ThreadStart( DoWork ) ); operation = AsyncOperationManager.CreateOperation( null ); workerThread.Start(); int i = 0; while( true ) { Console.WriteLine( string.Format( "Hello from {0} {1}", Thread.CurrentThread.Name, i++ ) ); Thread.Sleep( 500 ); } } static void ShouldBeInMainThreadCall() { Console.WriteLine( string.Format( "Calling you from {0}", Thread.CurrentThread.Name ) ); } } } Cheers Lee Tag: is there any speed difference between a TVF CLR that returns an array vs yield as each result is ready? e.g. does returning the array all at once cause sql server to allocate more efficiently?
