Hallo,
ich brauche eine Eingabezeile mit Return (war schon oft, ich weiß). Problem ist, dass mein Compiler (Borland C++ Builder 2005) in der Unterklasse die Variable m_EditProc nicht mag, Fehler im Datentyp. Kann jemand mal nach Sinn und Unsinn durchschauen, ich bin völlig neu in Windows-Programmierung.
(Ohne Unterklasse und ohne Return funktioniert das Programm.)
Grüße,
Martin
