[perl-win32-gui-users] The correct way to put -addstyles in pm modules

[Guillem Cunillera Wefers]

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 ,

Guillem
