Callbacks

I am currently working on a project and I want to know how to utilize callbacks. If it makes a difference i am using vc .net. Which makes the MFC example slightly difficult to follow. As I read a previous thread (creating a callback method in C++ ) I noticed someone commenting on the existence of less convoluted examples.
I was polling for frames, but I realized that this is not suitable for what I am doing. Thus I need to know how to initialize callback events on vc .net.
Thanks!

Here is a link to a website which might have some examples of frame callbacks in C++:

It comes form this thread on our forums:

Hello as I try to figure out callbacks in the VC .net framework I have hit another dead end. I checked the following link
http://surfacetracker.sourceforge.net/ which has some very useful information.
Any further information will be greatly appreciated!
Below is a small section of what I'm trying to do:
/*inside the main function I have the following but it does not work, what I'm attempting to do is declare a pointer to the function FrameAvailable such that when a new frame is available my function FrameAvailableHandle is executed
I know i'm doing something wrong, but I don't know what?
*/
void(*FrameAvailableHandle)(struct INPCamera *pCamera); // where FrameAvailableHandle is the function that will be executed everytime there is a new frame
FrameAvailableHandle=(void *) FrameAvailable(); //where FrameAvailable is the Method

Please check out the "C++ VC8/2005" sample posted to our website. I'd recommend searching the entire project for "FrameAvailable" to see what you may be missing.
