• Visual C# using vs try catch

  I know that using can be used on class that implement IDispoable so that the object can be diposed of when finihsed with. But how can execptions be trapped that are particulat to that class. For example I have using ( System.Net.Mail. MailMessage message = new System.Net.Mail. MailMessage() ) { code in between , what if i get a MailMessage error how can I trap that speciffically } thanks javahar Javahar wrote: I know that using can be used on class that implement IDispoable so that the object can be diposed of when finihsed with.

• Visual Studio 2008 (Pre-release) How can I get the Drawing of a Button for rendering on an Adorner?

  I have a control, for example a Button, which i create in code and don't (!) want to display in the window directly. Now I need the Drawing of the Button to paint it on an Adorner, because, as I see, the DrawingContext only supports DrawDrawing(..). How can I get the Drawing of a Button because the following sample just doesn't work since I never get a DrawingGroup back from the VisualTreeHelper.GetDrawing(foo) function: //my adorner OnRender method: protected override void OnRender(DrawingContext drawingContext) {     Button foo = new Button();     foo.Content = "bla";     DrawingGroup drawingGroup = VisualTreeHelper.GetDrawing(foo);     if (drawingGroup != null)    ...Show All

• Visual Studio Team System TF60032: The VSS Converter requires Visual Sourcesafe 2005... HELP!!!

  First off: Major gripe here; Why would I need to purchase VSS2005 if we just shelled out $8000 for TFS and CAL's What do I need to do to get this to work Can anyone tell me how I do the VSS2005 setup I have tried searching through the forums here with no end. Furthermore: I don't have the MSDN access level to download VSS2005 as it would appear others have resorted to. I tried the VS2005Team 180day trial, but cannot find VSS2005 there either. I have re-installed TFS. I have also tried the beta service pack to no avail. I have spent (wasted) countless hours hunting for the elusive VSS2005 install. Oh, TFS itself works fine... just need sourcecode.. Please, Please help, -David Well, I guess there is no solution other th ...Show All

• .NET Development Class getting destructed through Interop

  I have a .net 2.0 assembly that is exposed through a COM callable wrapper (CCW). The destructor of my managed class is getting called prematurely. The library making COM calls is almost certainly not CoUninitialize-ing the instance, so I don't know where this is coming from. Is there a way to see the origin of such a call (nothing on the vs2k5 debugger's callstack) The time that this happens is pretty predictable, resources aren't low or anything. I can't even find much reading material on this subject. Anything relevant would be appreciated. Tony I may have found the problem. The native library making COM calls was not altering the reference count with AddRef/Release. In my defense, I've never used C ...Show All

• Visual C# FileNotFound Exception when trying to invoke compiled Assembly

• SQL Server Replicate stored procedures to many db's????

  Hi all. The company I work for has several developers and each has his own database. They are all identical....each developer has his own so that he/she can work with data and not bother the other developers. However, if one developer is assigned a category like billing and that person creates/modifies a stored procedure then that person needs to replicate those changes to all databases so everyone is in sync. Granted, two people will never work on a category at the same time (at least not yet). Right now, we have a script that does a good job copying the alter proc to all databases...works really well. So my question is, how do you guys handle a similar situation Anything better/worse Thanks! cbmeeks W ...Show All
