I don't like that code snip.

You can exclude the timer code and the configuration code. Just note that the mouse update routine I'm using here has the option to check the mouse ONLY if the correct time interval has passed. You don't necessarily need that... but I DO use this to POLL the MOUSE ONCE in my loop lets say, THEN I NEVER ACCESS the mouse again... instead I access these values I "Stored" of the mouse, so I never get messed up resulted for reading mousemove functions twice or something.
Hope this is helpful...
NOTE how I calculated my own MouseMovedX, MouseMovedY, MouseMovedZ. For your ZWheel thing, you could just do:
if(UserInput->MouseMovedZ<0){
// do this
}else{
if(UserInput->MouseMovedZ>0){
// do that
};
};
