How can I make the progress bar update fast enough?

Question

I\'m using a progress bar to show the user how far along the process is. It has 17 steps, and it can take anywhere from ~5 seconds to two or three minutes depending on the weath

I have the same problem. I have a form with multiple progress bars (top one is for example file x/n, bottom one is task y/m) The top progress bar does not update TIMELY while the bottom one does Programatically I update it, invalidate, explicit process message, refresh or sleep does not fix it. Funny thing is that bottom progress bar and other component (time elapsed text) updates fine. This is purely a Vista+theme problem (animations like previously suggested, XP or Vista with classic theme works fine. When displaying a message box after the top progress bar has travelled to 100 (programmatically, not visually) I first see the message box and then I see the progress completing

I found that SetWindowTheme(ProgressBar.Handle, ' ', ' '); as explained on Disabling progress bar animation on Vista Aero works (but I have old style progress bars now)
