How to stop a form from closing after validating a field

[blogmad]

Hi,
I've got a close button on my form as follows:
Private Sub exitForm_Click()
DoCmd.Close
End Sub

In the beforeupdate event of the form I have have following code to validate the forms fields:

Private Sub Form_BeforeUpdate(Cancel As Integer)
'Place an asterisk (*) in the Tag Property of the text boxes you wish to validate.
'Then in the BeforeUpdate Event of the form, copy/paste the following:


Dim msg As String, Style As Integer, Title As String
Dim nl As String, ctl As Control


nl = vbNewLine & vbNewLine

For Each ctl In Me.Controls
If ctl.ControlType = acTextBox Then
If ctl.Tag = "*" And Trim(ctl & "") = "" Then
msg = "Data Required for '" & ctl.Name & "' field!" & nl & _
"You can't save this record until this data is provided!" & nl & _
"Enter the data and try again . . . "
Style = vbCritical + vbOKOnly
Title = "Required Data..."
MsgBox msg, Style, Title
ctl.SetFocus
Cancel = True
Exit For
End If
End If
Next
End Sub

This validation works fine up to a point. If I try to close the form and a required field is empty, I get a message box asking me to fill in the data. The problem is that when I click ok to the message, it shuts down the form, so I have to re-enter all the data again. My question is how do I prevent the form from closing after clicking ok on the message box?

appreciate your help

It looks to me like all you're "cancelling" is the update, so of course the form proceeds to close. I think you need to change your close button to include an if statement, something like
If myupdate()=true then docmd.close

Then create function myupdate() to return TRUE if everything gets updated correctly.

Hope that helps.
