At this time, our window is up on the screen. But it cannot receive input from the world. So we have to *inform* it of relevant events. We accomplish this with a message loop. There's only one message loop for each module. This message loop continually checks for messages from Windows with GetMessage call. GetMessage passes a pointer to a MSG structure to Windows. This MSG structure will be filled with information about the message that Windows want to send to a window in the module. GetMessage function will not return until there's a message for a window in the module. During that time, Windows can give control to other programs. This is what forms the cooperative multitasking scheme of Win16 platform. GetMessage returns FALSE if WM_QUIT message is received which, in the message loop, will terminate the loop and exit the program.
TranslateMessage is a utility function that takes raw keyboard input and generates a new message (WM_CHAR) that is placed on the message queue. The message with WM_CHAR contains the ASCII value for the key pressed, which is easier to deal with than the raw keyboard scan codes. You can omit this call if your program doesn't process keystrokes.
DispatchMessage sends the message data to the window procedure responsible for the specific window the message is for.
