Re: Exception launcing processes

Sorry, you're right, but I trusted on goodness of emulator (what a
stupid!!). Next time I'll be more careful on details.

I'm sure that my other response is right, then. We ***NEED TO KNOW*** when
you're claiming some behavior and it's on the emulator, too. That's
critical information!

I tried to reset emulator and now no exception occur. I suppose that
was related to the process managing of emulator.

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

You realize that you posted this to a Windows CE, not a Windows

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
