Hi everyone, I'm trying to abort exiting the program if user choses no to exit on a msgbox. that sets the var AbortTask = true. this that I wrote doesn't work. I don't understang why...

Can somebody help me?

Private Sub Form_Unload(Cancel As Integer)
    If LoadingBar.Visible = True Then
        Cancel = 1
        Exit Sub
    Else: End If
   
    If AbortTask = True Then
        AbortTask = False
        Cancel = 1
        Exit Sub
    Else: End If
End Sub

The msgbox must be from another form or sub, so I have to work with a boolean var I guess.

Rather use the QueryUnload even for checking if the user really wants to close:

Private Sub Form_QueryUnload(unloadmode, cancel ... i don't know the arguments by heart)
    If LoadingBar.Visible = True Then
        Cancel = 1
        Exit Sub
    End If
   
    If AbortTask = True Then
        AbortTask = False
        Cancel = 1
        Exit Sub
    End If
End Sub


Alternative:

Private Sub Form_QueryUnload(unloadmode, cancel ... i don't know the arguments by heart)
    If LoadingBar.Visible = True Then
        Cancel = 1
        Exit Sub
    End If

    if unloadmode = vbFormControl then
       if msgbox ( 'do you really wanna quit?', vbyesno ) = vbno then
         cancel = true
       endif
    endif    

End Sub

Where do you define AbortTask variable?

You should define in module as Public not on the form

Is the variable global?
When do you set it?
If the Unload procedure is in several Forms, the variable will be reset the first time that it is encountered.
I suggest stepping throught the code (set a breakpoint on the first line of the sub)

Yes the var is set on a module as this: Public AbortTask as boolean
When the program is load it is set as false.

I tried query unload too, and it didn't work. don't know how...

I also made the breakpoint and the form actually passes the line: Cancel=1 it stops there. but afterwards, the program exits!

Cancel = 1 should prevent the form from unloading, but if you have an End statement the Unload event won't stop that.

'The message box should be placed in the quesryUnload event, and anywhere you want
'to exit just put "Unload FormName" or "Unload Me". Never use End anywhere in your form except as the last line in an Unload event,
'and try this code:

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
If MsgBox("Do you wish to exit", vbQuestion + vbYesNo, "My Application Control") = vbNo Then
    Cancel = True
    Exit Sub
End If
End Sub
