Is there any known behavior changes in the Valid Event?

[pcwc66]

I want to know whether there is any behavior changes in the Valid Event from VFP 6 SP5 to VFP 8 SP1 due to fixes or changes. In VFP 6 SP5, I kind of remember if Valid Event of a control is returning 0, the control will lose focus even though it should not according to Help. But in VFP 8 SP1, it won't.


Thank you for any info.

Yes, there was a change. You can't call the GotFocus() method of another control from inside a Valid.

Hi Craig,

I'm not aware of this GotFocus() change. Is this undocumented change? I remember that we use to able to SetFocus() in the Valid event but then it was changed in VFP 6 (don't remember exactly which version).


Thank you for your help.

AFAIK, you've never been able to change the focus from a valid method.

As far as returning 0, if the control was losing focus, that was a bug (I don't remember that one). Even in 2.x this was working properly, i.e. returning 0 from a valid kept the focus on the control.
