SetWindowPos and MoveWindow make it disappear. What do I have to do to make it redraw/paint/whatever?
Code://WM_SIZE in a dialog's procedure
case WM_SIZE:
SetWindowPos(hListData, NULL, 0, 0, MainRect.right, MainRect.bottom, SWP_NOZORDER|SWP_SHOWWINDOW);
//or
MoveWindow(hListData, 0, 0, MainRect.right, MainRect.bottom, TRUE);
