You'll have to show us the code for the procedure you mention above. 
It's a bit confusing, since there shouldn't be any "input statements" in 
a Windows program. 

In general, however, you should check the fields when the user 
leaves the last field, or better, when she clicks on an "OK" button, 
signifying that all the necessary data has been entered. Your validation 
routine checks the contents of each entry field, and if invalid, sets focus 
to that field (and perhaps opens a message box explaining what needs to 
be done).
