>>Dear all,
>>I have a form for get some infos, in this form (GetInfo.scx) I have a command button that in its click event I put Thisform.text1.SetFocus in last line.
>>When I run this form separately, it works correctly. But when I call this form from another form with ( DO GetInfo.scx WITH 1,2 ), and when I click command button, I get error 2012 (Cannot call SetFocus from within a When, Valid, RangeHigh or RangeLow event )
>>WHY?
