Re: Exception launcing processes

Probabibly I should be explicit, however I'm developing for Mobile,
this code is fulli supported by WinCE.

Hi, I'd like understanding why, when I launch a process from inside my
application I receive or no an exception, depending on the program I
try to launch. This is the code I execute:

externApp = System.Diagnostics.Process.Start(fullnameApp, "");

IntPtr hwndExt = IntPtr.Zero;
do
{
System.Threading.Thread.Sleep(500);
externApp.Refresh();
hwndExt = externApp.MainWindowHandle; //this line throws
InvalidOperationException
}
while (hwndExt.Equals(IntPtr.Zero));

If fullnameApp = "/Windows/calc.exe", no exception occurr,
if instead fullnameApp = "/Windows/iexplore.exe" exception is thrown.

Analising both cases with debugging before executing the impeached line
I saw that in first case it has exited field and HasExited property =
false, instead in the latter, in a first moment exited field is false
and HasExited true, but then both became true, even if the process is
still alive.

Which is the reason of it?

Thanks,
Andrea
