Thanks, David. After I remove calling WaitForExit() and ReadToEnd(), the progressbar works now, but the Exited event function OnProcesited is not called, so the progressbar is always shown. How can I make OnProcesited() be called?

Private Sub OnProcesited(ByVal sender As Object, ByVal e As System.EventArgs)
Dim p As System.Diagnostics.Process
p = sender

    Dim rtnStr As String = String.Empty
    rtnStr = p.StandardOutput.ReadToEnd()

    If rtnStr.Contains(" FAST terminated normally.") = True Then
        rtnStr = rtnStr & vbCrLf & "Please click Postprocess -> View Output File in menu to view the file."
        updateViewMenu()
    End If
    progBarFrm.Close()
    progBarFrm.Dispose()

    Dim frm As New FormShowFASTResult
    frm.txtFASTResult.Text = rtnStr
    frm.Button1.Select()
    frm.ShowDialog()

End Sub


Private Sub Run\_Tool()

    Dim sAppPath As String = ".\\XXXXX.exe"
    Dim fileName As String = "XXXXX.txt"
    Dim p As New System.Diagnostics.Process()



    p.StartInfo.FileName = Application.StartupPath & "\\" & sAppPath
    p.StartInfo.Arguments = fileName

    'Do not use the system shell to start the program this is so we can hide the command dos window
    p.StartInfo.UseShellExecute = False
    p.StartInfo.WorkingDirectory = strOutputFilePath
    ' Show no dos window if false
    p.StartInfo.CreateNoWindow = True
    p.StartInfo.RedirectStandardOutput = True
    p.EnableRaisingEvents = True
    AddHandler p.Exited, AddressOf OnProcesited


    progBarFrm = New FormProgressBar

    Try
        p.Start()

        progBarFrm.Show()
        progBarFrm.Refresh()            
    Catch ex As Exception
        ShowValidationMessage("Unexception error is caught, please close and try again.", "Error")
        
        Return
    End Try

End Sub

You can't force it. Your external process just hasn't stopped yet for some reason. Does your external process wait for the user to "Press any key to exit"?? I sure hope not!
