WinForms not showing

I have an application that I designed in  What I am trying to do is upon clicking the exit button in my application I want another WIndows Form to show and perform my "backup procedure".  The situation is the backup procedure works and takes about15 seconds to complete.  However the form does not show up.  The main form just stays on the screen, and then after the backup conmpletes the program exits (which is what it is supposed to do upon completion of backup procedure).  

I want the backup form to show while it is doing the backup procedure because there is a progress bar on there that I want to display, of course, the progress of the backup.  How can I get the form to display without just executing tyhe code and not showing the form?  I have a frmBackup.SHOW and I have tried frmBackup.ShowDialog() but nothing shows the form.  It is loading because the form contains the backup procedure and it is running.

Any help is greatly appreciated.

Good suggestions above. If you move the backup code from Form.Load event to Form.Shown event, you form will show before the backup code executes. But for the progressbar to work, you would need to do some multithreading/backgroundworker.

Sounds like you need to move the actual backup code into another thread.  The BackgroundWorker() control is the easiest way to do this.

If you have a long running loop, however, you might be able to get away with simply placing Application.DoEvents() inside that loop.
Move the entire backup code to this new form, add progress bar in this form and add a backgroundworker to start backup in background.

Here is an example on how to use backgroundworker and progressbar together:-

Don't let the form return until the job is complete.
Also open this form on form_closing event of your parent form in frmBackup.ShowDialog();
