GenericCodeHook

[randy]

Hi , i developed a unit named GenericCodeHook , it will do a generic code hook by replacing the code location to be patched by a jump to the new location .
i have 2 functions :
CreateGenericCHook and RemoveGenericCHook .

i use it like this :

Code: Select all

library GenCHook;

uses
  windows,
  GenericCodeHook;

procedure Main( Reason : Integer ) ;
begin

  case reason of

    DLL_PROCESS_DETACH:
    begin
        Detache;
{
Detache:
will call the RemoveGenericCHook function
}
    end;

    DLL_PROCESS_ATTACH: 
    begin
      Attach;
{
Attach:
will call the CreateGenericCHook function
}
    end;

  end;

end;

{ *******************
  *** Entry Point ***
  ******************* }

begin

DllProc := @Main;
DllProc(DLL_PROCESS_ATTACH) ;

end.

But the problem is how could i inject it into the whole system using MadCodeHook library ?


many thanks

InjectLibrary(ALL_SESSIONS or SYSTEM_PROCESSES, 'dll.dll'); for madCodeHook 2.x

If you're using v3 it's a bit different, have a look here http://help.madshi.net/HowToUseMadCodeHook.htm

Thank you iconic , But when i use it with :
InjectLibrary(ALL_SESSIONS or SYSTEM_PROCESSES, 'dll.dll');

the System crashes .

Then probably your GenericCodeHook is responsible for the crash? Try injecting an empty dll. Does that crash still occur?
