 Posted: Wed Mar 04, 2009 1:03 pm Post subject: [Delphi] GetMemoryAddress of Delphi Function |
 |
|
procedure TForm1.Button1Click(Sender: TObject);
var
h:integer;
begin
h:=pointer(Application.Terminate);
showmessage(inttohex(h,1));
end;
It will not let me compile:
| Code: | Build
[Error] Unit1.pas(30): Invalid typecast
[Fatal Error] Project1.dpr(5): Could not compile used unit 'Unit1.pas' |
I assume Application has a "baseaddress" and Terminate is the offset. How can i get that address+offset for example?

I don't think this will work because you can't find out the pointer to something in a class like directx.
What I do is insert alot of nops before and after it then call Application.Terminate. Compile then look it up in a disassembler. |

If i am not mistaken he is talking about "@" in Delphi?

I told you what to do on Messenger -_-
(Add procedure lol; to private dec)
| Code: | Procedure TForm1.lol;
Begin
Application.Terminate;
End;
Button1.Click:
ShowMessageFmt( '%x', [ @TForm1.lol ] ); |
will raise an exception error, try doing what dark byte did (typecast it as Integer)
I'm not sure that THAT function itself is even a standalone, it's just a wrapper so it won't give you .Terminate (Application is the class and Ter is a member of it) address -_- |

as i said, when you compile and run your program, it doesn't really call Application.Terminate, as it's just a freakin' wrapper, example:
Procedure lol(text: string);
begin
ShowMessage(text);
end;
lets say you wanna get the address of lol, you can't because in the compiled program it's just regulary calling ShowMessage from your compiled wrapper. |

Rot1, i am using this code within a dll file, it will get the address of the procedure ... and ... the returned value will be from my DLL, but the thing which i call is in the executable.
So the address will be not what i wanted.

I don't think you can get the address of a function from another module unless it's exported.
