I have made a function that shows an Icon in the taskbar of windows98, and in that funtion I've told windows to make a callback message by using NOTIFYICONDATA structure.
My question now is, how do I make a funtion in my c++builder 5 that recieves the message from windows, when my mouse click's on the icon ???
I have read, that I should make a callback function, but I don't know how to do that. The function that I want to receive the windows message is called:
void On_MYWM_NOTIFYICON(WPARAM wParam, LPARAM lParam)
so I hope you know what is missing ???

Use in .h
LRESULT CALLBACK OnTrayNotification(WPARAM wp, LPARAM lp);
Use in .cpp
LRESULT CALLBACK OnTrayNotification(WPARAM wp, LPARAM lp)
{
   return (long)0;
}
