An CALLBACK function could be member of an class ?

[VictorN]

I am trying to use CDC::EnumObjects method just like this:

	CDC dc;
	dc.Attach(hDC);
	dc.EnumObjects(OBJ_PEN, EnumObjectHandler, 0);

from here: https://msdn.microsoft.com/en-us/lib...or=-2147217396

and

BOOL CALLBACK EnumObjectHandler(LPVOID lpLogObject, LPARAM lpData)
{
	return TRUE;
}

and it works.

My question is, can I move this function, in an class, as member function (method), but, most important, without changing as static ? Yes, I can put here my trials, but none of them had worked ... perhaps it is not possible what I am trying to do

Yes, you can.
for example, you can pass the this pointer as a lpData parameter.
Then from within this static Callback function you'll be able to call any of your class members using the passed in this pointer.
