I have been doing off/on development with visual c for a couple of years and am getting quite adequate... but one thing that continues to kick my butt is a callback function. I know the concept and how it should work, but whenever I try to implement one, I always fail... well, now I have to succeed and am pleading for help :) My question: I am trying to implement the callback function associated with the URLDownloadToFile function. For the callback function pointer, it takes a LPBINDSTATUSCALLBACK pointer. Can anyone help me define a function and a pointer of this type? Any assistance, pointers, or example code is much appreciated. TIA, Garritt
