progress bar troubles

hi all,

trying to a write a small app to learn more about c#. was hope to make a simple app to display a progress bar while i started and ran a process in the background (defrag). problem i run into is waiting for the process to end. what eve i try to use to suspend the thread (thread.sleep or WaitForExit()) either one causes the progress bar to stop. is there a way around this?

code is pretty simple, go the progress bar code here (http://www.codeproject.com/cs/miscctrl/C_NeverEndingPBar.asp)

private void btnAccept_Click(object sender, EventArgs e)

{

osProgress1.Visible = true;

osProgress1.AutoProgress = true;

}

private void StartDefrag()

{

ProcessStartInfo psi = new ProcessStartInfo("Defrag.exe", "-c -f");

psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

System.Diagnostics.Process listFiles;

listFiles = System.Diagnostics.Process.Start(psi);

listFiles.WaitForExit();

as soon as it launchs defrag and starts waiting it causes the progress bar to hang. any thoughts?

thanks in advance!

hi, thanks for the info and yes, i finally broke down and used a methodinvoker to start a second thread where defrag lived and let it run in the second thread. :) fixed and working great now!

Hi,

How do you call the StartDefrag() method?

This should be on another thread so that the main thread can update the Progress Bar.

Hope this helps
