My first approach was to create a modeless dialog and update the file list and progress bar as I go. But my problem is the dialog never finishes displaying before processing begins, so I can't use the Cancel button. I'll assume its because I'm in a loop and never return to the system to process the dialog messages. I tried doing a PeekMessage but that doesn't seem to help.

void CYourParentDlg::ProcessIdleMessages()
{
	MSG msg;
	while(::PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
	{
		if (msg.message == WM_QUIT) //maybe already closing
		{
			::PostQuitMessage(0);
			break;
		}
		if (!PreTranslateMessage(&msg)) //allow other messages to process
		{
			::TranslateMessage(&msg);
			::DispatchMessage(&msg);
		}
	}
}

float s = 5.0;
SendMessage(hWnd, msg, 0, (LPARAM) &s);
