I've developed mine a long time ago.
But I know I have to set

_vfp.autoyield=.f.

before seting the actiondz property to 8
Without this, it's not guaranted that VFP processes Windows Events while processing its own code.

I also set the

BackgroundProcessFlag to .T.



>I am running a form that uses the Dynazip dzStActxCtrl progress bar. I placed code in the UnZipMajorStatus and UnZipMinorStatus methods of dUzActxCtrl. These methods are meant to catch the callbacks (I guess) made to dUzActxCtrl. In those methods I set the desired progress bar properties.
