Posted By:      Posted Date: September 02, 2010    Points: 0   Category :ASP.Net
 
I have some code that gets the exception Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack. I have pasted some code below. I have confirmed that I am in mixed mode debugging, (native and managed). I have also confirmed that I am not 'pre-compiline' b4 debugging. the code is for a 'csv' download. Can someone help? Response.Clear(); Response.ClearHeaders(); //set the conttent type of the file to be downloaded (IF NEEDED) Response.ContentType = "application/vnd.ms-excel"; // initialize the http content-disposition header to indicate a file attachment with the filename Response.AppendHeader("Content-Disposition", "Attachment; Filename=\"" + strFileNameCSV + "\""); //// transfer the file byte-by-byte to the response object FileInfo fileToDownload = new FileInfo(strFileNameCSV); Response.Flush(); Response.WriteFile(fileToDownload.FullName); Response.End();

No symbols are loaded for any call stack frame. The source code cannot be displayed.

  
Hello.I installed VisualStudio.NET 2005 a few days ago.  ( not beta )While I'm debugging, I'm faced with strange message box.-- MessageBox --No symbols are loaded for any call stack frame. The source code cannot be displayed. -- Debug Detail Window --FatalExecutionEngineError was detectedMessage: The runtime has encountered a fatal error. The address of the error was at 0x7a2b5aec, on thread 0x358. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.How should I solve this problem?Please answer me..Thanks.Gwisun.

Code Optimized Web Development Profile (VS 2010 and .NET 4.0 Series)

  
When you first run VS 2010 it prompts you to select an IDE profile to use. The profile you select will configure how tool windows are displayed/docked in the IDE by default and set the default keyboard shortcuts. You can then customize any of these settings by using the Tools->Options menu within the IDE and then override/change them. You can also later reset your profile and pick a different one by choosing the Tools->Import and Export Settings menu command.

call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Wrappers: Use Our ManWrap Library to Get the Best of .NET in Native C++ Code

  

By now you're probably used to reaching into the .NET Framework using Managed Extensions with your C++ code. But what do you do if you have legacy apps that use older versions of the compiler, or if you want to avoid some of the CLR requirements? Well, you can wrap Framework classes in a native way so you can use them in any C++/MFC app without /clr. Paul DiLascia shows you how.
