[RESOLVED] [2005] ProcessStartInfo Question

[vbdc]

Hi All,

English is not native.

I using the following code to extract files in console windows which is hidden.
I want to make this process "wait" and not continue with the next line of my application until this process has been finished and then execute the next line of code.
how can I do that?

Try
            'Using the 'EXTRACT.EXE' to open cab files
            Dim MyProcess As New ProcessStartInfo("extract.exe", "/e bla.cab)
            MyProcess.CreateNoWindow = True
            MyProcess.WindowStyle = ProcessWindowStyle.Hidden
            Process.Start(MyProcess)
        Catch ex As Exception
            MessageBox.Show("Extracting Files Error", "BLA", _
            MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try

the process has a WaitForExit method, but it blocks the thread so what you should do is use AddHandler to add an event handler for the Exited event:

Try
            Dim MyProcess As New ProcessStartInfo("extract.exe", "/e bla.cab")
            MyProcess.CreateNoWindow = True
            MyProcess.WindowStyle = ProcessWindowStyle.Hidden
            Process.Start(MyProcess)
            AddHandler MyProcess.Exited, AddressOf ProcessExited
        Catch ex As Exception
            MessageBox.Show("Extracting Files Error", "BLA", _
            MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try 
 
Private Sub ProcessExited(ByVal sender As System.Object, ByVal e As System.EventArgs)
            'Do what you need to do after the process has exited in here
End Sub

hi Atheist
Ok, the ProcessExited does not start automaticly and I should call it.
What type of agruments should I pass to 'ProcessExited' sub?

Thanks

Solved.

I had to add the following line:

MyProcess.SynchronizingObject = Me

Thanks
