I've decided to try to bypass mouse_event for practice, and i've done a little resource, but i'm a little confused about the return type

msdn "mouse_event Function()"

Quote:

Return Value

This function has no return value.

So, i should set the return value as a bool?, cas im pretty sure, i will need to make it a function, and not a procedure (a funtion has a return value, a procedure doesent)

Hey, i've tried hooking it and it seems that GG hooks mouse_event() in a diffrent method, btw no return value means you just simply use it, for example here's a function that returns a TRUE value:

Code:

Function TrueORFalse(var tOf:Boolean):Boolean; //bool
begin
if tOf = False then
Result:=True;
end;

Procedure lol;
begin
if TrueORFalse = True then ShowMessage('Return value is TRUE!');
end;

btw, i checked MSDN further and mouse_event uses SendInput();, and SendInput is hooked on both ring3 and 0, so we're fucked (not for sure)

here's a simple check to see if WriteProcessMemory() has successfully worked (Return value 1 = Success, Returen Value 0 = Failed)

Code:

BOOL WPM = WriteProcessMemory(hProcess,...)
if (WPM) //if WPM = True (success)
printf("WPM Success @ %d\n", WPM)
else
printf("WPM Failed @ &d\n", WPM);

it will printf 1 if it worked or 0 if it didn't work

it will printf 1 if it worked or 0 if it didn't work

Kay, ty... Wich means i cant make an AC, that will work both outside/inside MS?, or will it work with a handle as "0"?

Look what i did, i made a simple app with Timer and a Procedure that simulate 1 click.

when i click F2 it will call that Procedure 1 time.

so what i did is, i tried clicking on other Apps while GG was running, it works but NOT on MS itself.
