    Make form deactivate itself?

    Is it possible to make a form deactivate itself without minimizing it?

    I have written a small utility which copies selected files from CDs
    (hundreds of them). I put a CD in the tray and click a button on the form to
    tell it the next CD is ready for it to process. Each CD takes a few minutes
    to copy, and the form has a textbox at which I glance to see the progress. I
    have the form sending itself to the back, but it would be nice if it would
    also relinquish focus to the previously active window.

    ..NET 1.1

    Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
    System.EventArg s) Handles Button1.Click
    Form.ActiveForm .SendToBack()
    Form.ActiveForm .Deactivate() ' no such method :-(
    ' process CD

    Only a few hundred more CDs to do...

          No, that doesn't work, it just disables the form while leaving it as the
          active window and the only way to close it then is through the Task Manager
          :-(

              Well, how is the form displayed? If it's by using .showdialog(), then
              what you want is not possible because that dialog is then modal.

                  It's a simple Windows application. I couldn't find anything in the Windows
                  API docs on the MSDN website - although that doesn't mean there isn't
                  anything. Maybe there's a more relevant newsgroup for me to ask in?

                  I've done a couple of screen-grabs of what to show what does and what I'd
                  like to happen:
                  http://www.in-press.co.uk/windowsamp...dowsample.html (22KB)

                  There's only about 100 CDs left to do now, so there's no need for a solution
                  any more.

                      For the benefit of anyone reading this in the future...

                      As I reach the end of the task, I found the GetWindow function in
                      user32.dll, with which I could have retrieved the window handle to the next
                      window in z-order (i.e. the previously activate one) so, with the handle, I
                      would have been able to activate that window.
