Verify if a text box = 0 is has nothing in it?

[rhuns]

I am trying to verify if a text box is equal to 0 or is blank before the close button is pushed. The code works if the box equals 0 but not if it is blank. Can anyone help me with this. Here is the code:

Private Sub Command33_Click()
UnusedHRS.SetFocus
If UnusedHRS = 0 Or UnusedHRS = Null Then
    DoCmd.Close
ElseIf UnusedHRS <> 0 Then
    MsgBox "There are still hours that are unaccounted for", vbInformation, "Staffmark"
    End If
End Sub

If I can understand you properly then try this:

Private Sub Command33_Click()
 If Me.UnusedHRS = 0 Or IsNull(Me.UnusedHRS) = True Then
  DoCmd.Close
   Else
       MsgBox "There are still hours that are unaccounted for", vbInformation, "Staffmark"
Me.UnusedHRS.SetFocus
    End If
 End Sub
 

If still not working replace

IsNull(Me.UnusedHRS)=True

in line#2 with

Me.UnusedHRS)=" "

Cheers..Hope this helps. Note: Using "Me" makes the code run faster.

Thanks Jerry, for the help the IsNull() worked perfectly!

Private Sub Command33_Click()
    UnusedHRS.SetFocus
    If Nz(Me.UnusedHRS, 0) = 0 Then
        DoCmd.Close
    Else
        MsgBox "There are still hours that are unaccounted for", vbInformation, "Staffmark"
    End If
End Sub

I would consider putting this code in the Form_Close() event procedure instead. Otherwise the form could be closed another way and it would work fine, thereby leaving hours unaccounted for.

PS. Using IsNull() is also a perfectly reasonable approach. I prefer Nz(), but that's my personal choice.
