VS 2008 winforms does not simulate after build succeeded

It is probably executing but you just don't see execute. Have you ever executed a command-line program from Windows Explorer? Do you see it execute? You won't see most command-line programs execute when you execute them from Windows Explorer. It is normal behavior. There are many tricks to get around that; one I use is to simply put a breakpoint on the last line of the Main function.

Note that in my first reply I said:

Sam,

I tried running the project without debugging and it is working. It is only when I compile by pressing "F5" or "Start with Debugging" that's when it does not simulate. Otherwise "Start without Debugging" shows the application I created.

Seems that there something wrong with the Debugger. I have uninstalled and re-installed fresh VS 2008 and also updated all the service packs. Still no luck.

It sounds like it might be difficult to figure out. So it is critical that you provide the complete and accurate error messages. If you can provide copies of the windows you see showing the problems then that might help. If you want to you can put a project in a zip file and upload that. Generate a new project, then build it without any changes and if it does not work then zip it up and upload.

One thing you can try is to re-install Visual Studio. That will take time of course but if it fixes the problem then that will be easier than trying to diagnose the problem.

Hi Sam,

There doesn't seem to be any problem in the code because it was compiling properly when my PC got infected with some spyware unfortunately. However it has been resolved but the visual studio does not seem to run the application. I created a test win form application by creating a new project and it showed the same symptoms. The visual studio starts debugging and it also displays that the build is succeeded but it does not execute the application. It also displays an error window saying "Cannot run the project". It basically points to MS Visual Studio error.

I don't know what you mean by "resets and stays in the VS window" and "simulate my project".

Do you know how to use the debugger? Do you know how to single-step using the debugger? You should try doing that.

The most likely cause is that there is an error in the program that is being ignored. Your program should do something to catch errors, such as using try/catch. It would be a good idea to add code such as that; even if it is not relevant to the current problem, it could help in the future.

Use of the debugger however can help you determine the specific error that is the current problem.
