Starting C app using .Net (API issues in C App)

    Hi All,

    I have a c# .Net application that is responsible for monitoring processes and starting them if they dont exist, see code snippet below:
    ProcessStartInfo psiStartDetails = new ProcessStartInfo();
psiStartDetails.FileName = "C:\\MyApp.exe" //C Application
Process proc = new Process();
proc.StartInfo = psiStartDetails;
proc.EnableRaisingEvents = true;
proc.Exited += new EventHandler(StartProcAgain);
 
proc.Start();

    The problem with this is the C application "myApp.exe" uses the FindFirstFile Api to check for the existence of a file, this does not return the expected result for if the file exists or not, but works fine if you double click the exe to start it.

    I tought it was down to permissions using .Net so i checked this out in VB 6 using the Shell command (Same issue).

    I then created a batch file to start the C app (this worked).

    Anyone have any ideas why the Process.Start & Shell commands seem to disable the FindFirstFile API?
