[RESOLVED] is there any problem betwen graphics effects and usercontrol?

i'm using visual basic 6.
i have some graphics functions(api functions) that works fine in a normal program.
but when i put them in an usercontrol they(or some) are ignored or the image desappear...
can anyone help me?
thanks

What are they and how are you using them?

look this group project: in usercontrol control there is GraphicMirror() procedure, these procedure call the mirr() procedure that is in Graphics module.
you will see that in test form, the animator gif image is working fine(exccept in one little refresh problem), but in other images is ignored. can you help me?
(the black and white graphic effect is ok, but the others have problems too)
thanks

the problem is that, in teste form, i was using the change combox insted, click event...
thanks
