I am testing my program in order to avoid the warnings of -w option.
 
Firslty question:
    Is possible to avoid the continous warning which appears when the program call Win32::GUI::Dialog ?
 
Second :
     Which is the correct way to reference the constant in .pm modules ?
    I find people who write thinks like:
 
    -addstyle    Win32::GUI::constant("WS_VISIBLE", 0)
 
    what is this 0 ?
 
 
Thanks again ,
