message box with yes/no option

[Guest]

Hello,

I have a command button on my Travel Details (TD) form that takes you back
to main switchboard. On the TD form there a number of text boxes that hold
temporary data for as long as the form is active.
If a user by mistake exits this form all the temporary data are lost. I
would therefore like to have a message box that comes up with the question
"Do you want to exit the TD form? also with "Yes" or "No" option before the
user can exit the form.

If MsgBox("Are you sure you want to exit and lose all data?", vbYesNo,
"Exit?") = vbYes Then
DoCmd.Close acForm, "YourFormName"
Else
'do nothing
End If

Alylia,
Use the OnUnload event. It has a Cacel function...

Private Sub Form_Unload(Cancel As Integer)
Dim Response As Variant
Response = MsgBox("Do you want to exit the TD form?", vbYesNo)
If Response = vbNo Then
Cancel = True
End If
End Sub
