Zitat:
Wenn ich jetzt den Button2 drücke holt der den text auch raus (das prüfe ich in dem ich ihn danach ausgebe). Klicke ich danach auf den ersten Button zum abspielen geht das jedoch nicht...
Das selbe Verständnisproblem - quelle ist lokal und wird bei jeder ankommenden Windows-Nachricht neu angelegt und initialisiert.
Naja... Wie gesagt... Genau über dieses verständnis problem habe ich bereits nachgedacht.. Doch leider wird die quelle bei einer neuen windows-nachrricht nicht neu initalisiert... Dann funktioniert es einfach garnicht mehr...
Vielleicht weißt du ja wieso das nicht klappt.
Das neu gelernt ist weitestgehend eingebaut.
ChildProc 2 ist nur der wichtige Teil. Der rest zeigt nur wie ich die fenster etc erstellt habe falls das wichtig sein sollte.
Hier mal der richtige quellcode:
