case 9001: { RECT theRect; ShowWindow (hChild, SW_RESTORE); GetClientRect (hWnd, &theRect); ValidateRect (hWnd, &theRect); InvalidateRect (hChild, NULL, TRUE); SetForegroundWindow (hChild); SetFocus (hChild); UpdateWindow (hChild); BringWindowToTop (hChild); break; }dankw, für antworten, der Tipp mit den Koordinaten (von Stealth) hat zur Lösung
geführt. so wie' s oben steht, gehts!![ Dieser Beitrag wurde am 10.06.2003 um 22:33 Uhr von N00Bie editiert. ]
