What does Query_unload event do in VB? Why we need Form _unload event?..

Answer / amirthraj

Query_Unload event is fired, when the form is actually
preparing for unload. Whereas Form_Unload is triggered when
form is unloaded. It's possible to stop the form unload
from Query_Unload event by setting its Cancel argument to
True.

What does Query_unload event do in VB? Why we need Form _unload event?..

Answer / parmanand

Query unload means your form is about to close but still not
closed.

Form _unload means your form is released from the memory and
its totally closed. Hence if you want to display any message
you will keep it in Query unload , form unload will not work.

Ex.

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode
As Integer)
MsgBox "do you want to close the form ?", vbYesNo
if vbno then
Cancel = True
end if
End Sub
