Waiting for a process to finish

Hi experts,

I start a process using the following code;

Public pro As New System.Diagnostics.Process()
Public proMRDCL As Process

    Sub RunShellCommand()
            pro.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
            pro.StartInfo.FileName = strMYPATH & "QBExports\QBmrdclEX.stp"
            proMRDCL = System.Diagnostics.Process.Start(pro.StartInfo)
        End Try
    End Sub

What I want to do is send a character return to the process and then wait for the process to finish before killing it and my program carrying on running.

Can this be done?

If the Process is ending by itself, you can use WaitForExit. See details at http://www.utmag.com/wconnect/wc.dll?LevelExtreme~9,7,10,,176

Hi emoreau,

When i inserted the WaitForExit into my code, it freezes my pc at runtime.

Is there another way around this?

Hi Eric,

The demo works as it should but not how i want it.

I automatically open a program and run it. The amount of time the program takes to run is always going to be different  (Due to the amount of data and different machine speeds).

I want to be able to wait until the program stops running then close it and move the output files it creates into other folders.

Basically i need to know when the program has stopped running.

I have no idea. Can this program raise a signal to say it has finish?
instead of WaitForExit



msdn states "Causes the Process component to wait for the associated process to enter an idle state"
