Nachtrag:
ich hab jetzt mal von hand - immer wenn sich was an der CListCtrl tut - ein SendMessage(DrawItem eingefügt)...
theListCtrl->SendMessage(WM_DRAWITEM, 0, 0);
In OnDrawItem hab ich einfach mal den Code aus dem ListBox-Beispiel reingetan, um zu gucken, was passiert...der sieht so aus:
Das Programm steigt schon beim Holen des CDCs aus. Offensichtlich muß ich wohl beim Senden der Message noch die Parameter befüllen...aber wie??..wo soll ich dann beim Senden z.b. den CDC herbesorgen....kann mir da mal jemand auf die Sprünge helfen...(..warum muß MFC auch alles nur so überkomplizieren...ich will doch einfach bloß n Listeneintrag größer zeichnen....)
