Hello everyone,
I do have a database in which cotton processing data is entered. It has a Form in which Factories are added with the following Fields:
ID, Factory Name, Factory Type (Combo Box), Address, City (Combo Box), State (Combo Box), Contact #, Pin Code #, E Mail ID
It is a single Form.
What I need is, if the user closes the Form without selecting data either from all the Combo Boxes or any one of the Combo Boxes, a Message should appear and when the Message Box is closed the cursor should go to the particular Combo Box.
Please inform the VBA code for this.


Regards
Alex

Something like this code in the forms BeforeUpdate event:

If Nz([Factory Type],0) = 0 Then
   Cancel = True
   Msgbox"Select Factory Type"
   Me.[Factory Type].SetFocus
ElseIf Nz([City],0) = 0 Then
   Cancel = True
   Msgbox"Select a City"
   Me.[City].SetFocus
ElseIf Nz([State],0) = 0 Then
   Cancel = True
   Msgbox"Select a State"
   Me.[State].SetFocus
End If

put in all your checks into the ISVALIDFORM routine.
then if all are good, close the form in the UNLOAD event.

Private Sub Form_Unload(Cancel As Integer)
  cancel =not IsValidForm()
End Sub


'------------
Private Function IsValidForm() As Boolean
'------------
Dim vMsg
Select Case True
   Case IsNull(dtpWeekOf)
      vMsg = "Date field missing"
   Case IsNull(cboUser)
      vMsg = "Teacher name is missing"
   Case IsNull(cboSubj)
      vMsg = "Subject field is missing"
End Select
If vMsg <> "" Then MsgBox vMsg, vbCritical, "Required Field"
IsValidForm = vMsg = ""
End Function

Thanks Bob & Ranman.
However, not working.

Sorry Bob & Ranman, I made a mistake in the controls spelling. Now it works perfectly.

always use OPTION EXPLICIT in every module and it will eliminate spelling errors.
