I tried to change the cursor to other shapes and colors, but did not change.
A: In the dialog box / window / you need to add the processing of the WM_SETCURSOR message.
Bool MyDialog :: OnsetCursor (CWND * PWND, UINT NHITTEST, UINT MESSAGE)
{
// Todo: add your message handler code here and / or call default
:: setCursor (AFXGetApp () -> loadcursor (idc_mycursor);
Return True;
// Return CDIALOG :: OnsetCursor (PWND, NHitTest, Message);
}
You have no success because the window cursor style cannot be NULL.
