embeddedVisual C++-QUESTION!

I'm normally a .NET-Coder für CF, so I am kind'a new to eVC.
I need a very small application which only function is:

executing another application
writing a string "done" to a file in the same directory as the application

in .NET it would be some few lines of code, but I just dont know enough C++
to do it in eVC...

If someone could give me the code for this, I would be veeeery happy and

   you may use CreateProcess() to start another appliation and wait for exit something like

        CreateProcess( (_T("Process.exe"), NULL, NULL, NULL, FALSE, 0, NULL, NULL, NULL, &pi ); //Start Process... replace Process.exe with ur app path string
        WaitForSingleObject( pi.hProcess, INFINITE );

// Now open file and write to file using CFile or CStdioFile MFC Class

Thanks I will have a look at it. Where can I enter a comandline-string? at the first null?
Can it be just "-hello" or do I have to _T("-hello"), or something like that?
Sorry but I'm very new to C++...

You can input command line arguments to CreateProcess() function's 2nd parameter

CreateProcess(_T("App.exe"),_T("-Argument1 -Argument2")........

what do you mean by exit a eVC-App by code ?

Above code given by me will start process wait for process execution and exit......and if you want to terminate started process at any time then remove WaitForSingleObject() function from above and you may use TerminateProcess () API

Sorry for my unprecise question.
I want that the app does not wait until the started process has terminated. I want the app to terminate itself, the started process should not quit...

Thanks so much

then that your application should take care of iteself to terminate usign exit() or so.....
but there is no difference if application exits itself or it terminate using WaitForSingleObject() / TerminateProcess()
