Hey every one,

I'm experiencing a coding problem with ollydbg.

When i call an animation function from main plugin thread, it works. (of course it will work ). and here is a piece of correctly working code:

void ODBG_Pluginaction(int Origin,  int Action,  void* pItem) {
   if(Origin == PM_DISASM) {
	  switch(Action) {
		 case 0:
Go(Getcputhreadid(), 0, STEP_OVER, false, true);
			break;
	  }
   }
}

but if i call the same function from a thread it doesn't work (and here's a non working code):

DWORD WINAPI ThreadFunc(LPVOID dd) {
   Go(Getcputhreadid(), 0, STEP_OVER, false, true);
   return TRUE;
}void ODBG_Pluginaction(int Origin,  int Action,  void* pItem) {
DWORD id = 0;
   if(Origin == PM_DISASM) {
	  switch(Action) {
		 case 0:
CreateThread(0, 0, ThreadFunc, 0, 0, &id);
			break;
	  }
   }
}

I tried to suspend debugee threads before animating -> no luck;

I tried to use WaitForSingleObject after creating an event that I unset immediatly after calling animation function and set it from main plugin thread -> no luck (the example is a bit complexe)

Any help would be welcome,

Thank you.

I don't know what 'Go(...)' actually does, but maybe it fires a 'SendMessage'

somewhere, while it should use a 'PostMessage' from another (non-ui- !) thread

just to prevent deadlocks. Just a guess..

Hi

Why want to use a Thread?

Ollyscript or Olly Maschine use not a Tread

add in your code

Animate(ANIMATE_IN);

inline void CVM::DoAnimateInto()
{
	Animate(ANIMATE_IN);
	Go(Getcputhreadid(), 0, STEP_IN, 0, 1);
	ReturnToOD();
}

ANIMATE_IN was only an example

ANIMATE_OFF No animation

ANIMATE_IN Animate into

ANIMATE_OVER Animate over

ANIMATE_RET Execute till RET

ANIMATE_SKPRET Execute till RET, then skip RET instruction

ANIMATE_USER Execute till user code

ANIMATE_TRIN Run trace in

ANIMATE_TROVER Run trace over

ANIMATE_STOP Gracefully stop animation
