given this works for at least some MFC functions it suggests there is something about your project code that is confusing VA.
can you try pasting the following simple test into an existing cpp file, and see what happens?
static int calculateNumber(int nStart, int nMiddle, int nEnd)
return (nStart + nMiddle + nEnd) / 3;
static int getCounter()
rather artificial, but all i am interested in is the parameter information tooltip. using this code on my machine i am getting the expected, and correct tooltip.
if this works for you then can you try and produce a small sample from your library code base that i can try here, to see why you are not getting these tooltips?
