 Posted: Fri Jan 14, 2011 3:48 pm Post subject: [Feature Request] Add new option "Call function" |
 |
|
Add new option "Call function" in Memory viewer's tools menu, that would have inputs fox func address, return value type , param1 type, param1, param2 type, param2 ... paramN type, paramN.
This function could auto generate asm code that would do the call with given parameters.
You could use createremotethread to execute asm code. This could save my time, because then I wouldn't have to write C program every time I want to test some funcs.
Also CE made trainers could use function calls which means they can do more cheats with less work.

Not sure, but I think this is already possible:
| Code: |
fullaccess(00400500,4)
alloc(mycode,2048)
CreateThread(mycode)
mycode:
push param4
push (float)param3asfloat
push param2
push param1
call functionname
//eax contains a return value you can use for whatever thing you like
mov [00400500],eax //save result
ret //exit thread

Yeah, calling functions is working fine in both CE 5.6.1 and CE 6.0.
It doesn't fill in the parameters automatically of course, You have to do it manually, but it is working.

auto assembler window
memory view->tools->auto assemble (or just ctrl+a in mem view)

Great thanks.
I injected this following code, but it makes VLC crash. Any ideas about this How to fix that?
6A5A4200 is address that mutes sound ant is void.
if I want to use 1234 as arg, do I just push 1234, or do i have to convert that number into hex or something?
| Code: | fullaccess(00400500,4)
alloc(mycode,2048)
CreateThread(mycode)
mycode:
call 6A5A4200
//eax contains a return value you can use for whatever thing you like
mov [00400500],eax //save result
ret //exit thread |

I looked at VLC after reading your post and I don't see a function that mutes the volume that returns a void and takes no params.
libvlccore.dll holds the main handler code which I found the mute code is:
aout_SetMute - libvlccore.dll + 6BF30
aout_ToggleMute - libvlccore.dll + 6BF60
Both of these functions expect params and return values.
aout_SetMute seems to be the one called when you click the mute button, which is:
int __cdecl aout_SetMute(int a1, int a2, char a3)
a1 = vlc_object_t object pointer.
a2 = audio_volume_t object pointer.
a3 = boolean
The source shows Mute being called like this:
| Code: |
void SoundWidget::setMuted( bool mute )
{
b_is_muted = mute;
playlist_t *p_playlist = pl_Get( p_intf );
aout_SetMute( VLC_OBJECT(p_playlist), NULL, mute );
}
|
So you need to pass at least the vlc object and the boolean.

Is there any tutorial about how to find part that is often called? and how can i inject my code there? Do i need to overwrite original code or what?
Edit: from which cpp file did you find that function call?

It's inside of:
vlc-1.1.5\vlc-1.1.5\modules\gui\qt4\components\controller_widget.cpp
