Recently, I have a question.

i want to do something when i click a ole in a richedit,but i find that i can not get the accurate position of ole.

Now,one way to get the position like this.

the "rcLastUpdate" is the i am using.

sometimes,it is not accurate,when the ole is not visible.

	STDMETHOD(Draw)(DWORD dwDrawAspect, LONG lindex, void *pvAspect,	DVTARGETDEVICE *ptd, HDC hicTargetDev, HDC hdcDraw,
	LPCRECTL prcBounds, LPCRECTL prcWBounds,
	BOOL (__stdcall * /*pfnContinue*/)(DWORD_PTR dwContinue),DWORD_PTR /*dwContinue*/)
		if (prcBounds != NULL)
			m_rcLastUpdate.left = prcBounds->left + 1; = prcBounds->top + 1; 
			m_rcLastUpdate.right = prcBounds->right - 1; 
			m_rcLastUpdate.bottom = prcBounds->bottom - 1; 
		IViewObject_Draw(dwDrawAspect, lindex, pvAspect, ptd, hicTargetDev, hdcDraw,
			prcBounds, prcWBounds);
		return 0;

another way is that use "posfromchar()".

POINT posLeftBottom={PosFromChar(CPN).x, PosFromChar(CPN1).y }

cpn: the index of the ole .
CPN1: a char in the next line.

then i can get the position of the ole.

i think there must be a better solution.

so i want to know, how can i get the accurate position of ole?

thanks, recently asked more questions。 hoho,have more i should to learn.
