i have programming windows from the ground up and the book lists some listbox messages to send to it, and i want to get the number of strings in the listbox. so i'm going to send the message to the listbox and the message is LB_GETCOUNT. but, the book only tells me the message, not what i should set the WPARAM and LPARAM to. what do i need to set them to in the SendMessage function?
thanks!
