Hallo zusammen,
Ich habe da ein VB Programm gefunden, dessen Funktionalit�t ich gerne in c#
nachprogrammiert h�tte. Es verwendet eine Vielzahl von Apifunktionen.
Kann man das in C# nachbilden? Schon oder?
Was �berhaupt mit dem Programm gemacht wird:
Ein Screenshot von einem anderen Programm, dessen "Inhalt" wird dann optisch nach
Merkmalen abgesucht.
Unten jetzt nur mal die Definitionen, den ich denke, wenn ich das kapiert habe, klappt
der Rest wahrscheinlich leicht.
Problematisch ist z.B. GetBitmapBits da dort ein Parameter Any verwendet wird. In MSDN
ist das ein LPVOID // buffer to receive bits
Oder gibt es da einen einfacheren Weg unter c#?
Lg
