Re:Cannot close form on Error
Actually, there is a parent form with 7 buttons. The button-1's onClick event
is like this:
hide
set-flag to 1
myForm.ShowModal
show
For button-2 to button-7, they will set-flag-to-2 and set-flag-to-7
accordingly.
Then, they all call the same myForm.
Then, myForm's onShow event will
'select * according to the criteria basing on the flag'
For example,
button-1 will select those black-hair customers
button-2 will select those white-hair customers
button-3 will select those brown-hair customers
button-4 will select those red-hair customers
...
Of course, my appliction is more complicate on the selection criteria.
But, is there other ways to do this kind of things ?
