how to write a code to act on the yes and no on a message box

[Ryno Bower]

I have tried many thing and it just would not work.
Say I have a form with a close button on it. If I click on cancel by accident and the messeage box appears asking if I'm sure I want to close the form, and I don't want to. What coding do I use if I click no the it would just close the msgbox and leave the form open. However if I click yes, it should close the form.

Can a code be written to do this procedure?

You just need to insert the code you want for the condition Vbyes or Vbno.

Private Sub Command0_Click()
Dim x As Integer
x = MsgBox("are you sure you want to cancel", vbYesNo)
If x = vbNo Then
x = MsgBox("ok don't cancel", vbOKOnly)
Else
x = MsgBox("ok cancelling operation as requested", vbOKOnly)
End If

End Sub

You could try using a MsgBox here:

For instance, you could try:

Private Sub YourButtonName_Click()

If MsgBox("Are you sure you want to close this form?", vbYesNo + vbQuestion) = vbYes Then

DoCmd.Close

Else
Exit Sub
End If

End Sub

The code opens up a message box with the question, "Are you sure you want to close this form?"-- you can change this if you wish. If you click yes, the form will be closed. If not, it exits the subroutine. A pretty simple (but useful) fix. Should work for you here, I believe.
