I can't believe it, but I'm having trouble restricting input to an edit control. I only want the user to be able to enter in certain keys, but placing the restriction in WM_KEYDOWN didn't work:
The user can still enter anything into the edit control. How can I fix this problem?Code:case WM_KEYDOWN: if (wParam!='I') if (wParam!='V') if (wParam!='X') if (wParam!='L') if (wParam!='C') if (wParam!='M') if (wParam!='~') return 0; break;
