how to refresh a progress bar

[joelwenzel]

Hello,

I have a progress bar control in my project that shows the progress of a bunch of file processing. It works fine if I don't touch anything while the program is processing files. However, if I click on something else, the progress bar stops refreshing until the file processing is completed. Is there some way to force it to refresh/repaint/redraw/etc?

Thanks

Unless you want to go into multithreading (see faq116-5162) and such, you could simply pump messages whenever you update the progressbar. Call a function like this whenever you call the progressbar's SetPos:

void pumpMessages()
{
	MSG msg;    
	while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))      
	{
		TranslateMessage(&msg);         
		DispatchMessage(&msg);      
	}	
}
