In order to keep a handle on the process after starting it, I would use System.Diagnostics.Process, as that object gives you access to the process during runtime and keeps data after myProcess.EnableRaisingEvents = True ' ' Add an event handler. ' AddHandler myProcess.Exited, AddressOf Me.ProcessExited myProcess.Start() ' ' Event handler. ' Friend Sub ProcessExited(ByVal sender As Object, _ ByVal e As System.EventArgs) In both ways, the exit code of this process is zero. System.diagnostics.process Error Handling The following is a code-snippet I designed...For some reason I had to run a command from a C# application recently and I needed to capture and use the output.

I tried using the following, but it goes to catch.

As of now, my application has been used to open 196 databases. Beats me! From the documentation: p.Start(); // Do not wait for the child process to exit before // reading to the end of its redirected error stream. // p.WaitForExit(); // Read the error So why shouldn't System.Diagnostics.Process.Start(LocalPathString) work on its own, if you don't mind?
