Re: Herausfinden ob Prozess/Anwendung mit Delphi compiliert

hey,
ich hab da was heute gemacht, ich habs getestet mit ein paar delphi programmen und es scheint zu funktionieren, es ist ähnlich wie peid, prüft werte nach dem EntryPoint der datei und vergleicht sie mit fertigen signaturen, natürlich kann ich net versprechen das es immer funktioniert, jedoch hats hier mit Delphi6 + Delphi7 funktioniert, einwandfrei

naja, ich geh mal pennen, ich schau noch ob ich es irgendwie verbessern kann

ps: die signaturen sind nicht von mir, sondern von netz irgendwo her (glaub war für peid, weiß net mehr genau)
