Validating textbox meet new friends online dating sites
In the Before Update event procedure of the Microsoft Access form that you want to validate the data on for missing information, we can paste in the following code sample: Private Sub Form_Before Update(Cancel As Integer) 'Place an asterisk (*) in the Tag Property of the text 'boxes you wish to validate. Tag = "*" And Trim(ctl & "") = "" Then msg = "Data Required for '" & ctl. " & nl & _ "You can't save this record until this data is provided! For this we need to select the text box and from the Property window, choose the Other tab and type into the Tag property: Setting the Tag property of a text box to allow validation Repeat this process for any further fields that you need to prevent missing data from.'Then in the Before Update 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 = vb New Line & vb New Line For Each ctl In Me.

Putting all of that logic as properties on a control does not make the validation logic very portable.If you end up using the same business object in multiple forms you essentially have to rewrite the validation logic every time.
