Launch External Program

[Glenn Palomar]

Hi,

How will you know if an external program has launched successfully? I'm
trying to use System.Diagnost ics.Process class.

I know that you can check if the process has exited but can you tell if it
has launched it successfully?

Thanks,
Glenn

Re: Launch External Program

Well.. usually, if the process hasn't exited, then it's running! I guess in
your case, that's not the case :D

There's Process.Respond ing, which will tell you is the process is "active"
in the eyes of the OS.
I think that's all that could be useful.
Which process are you needing to know about??

Re: Launch External Program

I wanted my application to block until it has loaded the external
application (Inventor).

I guess I can put it in a while loop and wait until I get something when I
call Marshal.GetActi veObject.

I assume an exception is thrown if the file cannot be found, for example.
In addition you may waht to check the exit code returned by the started
application:

\\\
Dim p As Process = Process.Start(. ..)
p.WaitForExit()
MsgBox(p.ExitCo de)
///
