In one year ago, I wonder a serious problem accidientally!

It will be crash the VFP (both design time and run time ) on:

SelfdefinedProc(NVL(.NULL., _SCREEN))

but there is no crash for:

SelfdefinedProc(NVL(_SCREEN, .NULL.))
or
SelfdefinedProc(_SCREEN)

So, I said it is a joke on crashing the application! ;p

IT may be useful to make this terrible expire date on your application after you leave... ROFL!




I have download your gradient class in files section, it works very good!!

I want to make an animated change to both start and end color with timer!
Really make a advtermisment look! ^_~

Hey, any code for vertical gradient, maybe easy to change the word left to top, width to height...!?

^-^; Good Luck!
