I have a form that has many textboxes. I need to test that if all textboxes are Null then the record cannot be saved and if AT LEAST one textbox is not null then the record can be updated and saved.

I am using a loop but it is not working

For Each ctl In Me.Controls
        Select Case ctl.ControlType
            Case acTextBox
                If IsNull(ctl) Then
                    MsgBox ("Enter a time")
                    Exit Sub
                End If
        End Select
    Next ctl

Because the loop test each textbox whenever it comes to a tetxbox that is null then it exits the loop. I tried and put a Not in front of "IsNull(ctl) Then" line but it does not work.

There are 96 tetxboes on the form and I want to make sure that at least one textbox is not null before the record can be saved.

I am certain there is an short way of doing this without me having to write a long if statement for all 96 textboxes

Thanks for any help

If there are 96 text boxes, chances are not all of them are required. Your users will hate you (and so will management) if you punish them like this. Make only the most critical values required.

I am making an appointment calendar. Each text box has a label in incremental order 8:00, 8:10, 8:20, 8:30 etc all the way to 7:00pm. The textbox is realy a combobox where the user can select the patient name. So if a patient appointment is from 8:00 to 8:30 then they would fill the slots with the patient name.

They will not be punished because all 96 textboxes will not be filled immediately but during the course of the day. Also open slots are clearly visible on the form so it is easy to enter appointments in these slots.

I know this may not be the best way but with my limited knowledge it will work.

I hope this clarify my posting

Thanks

 
Which slots?

 

Then, when do they actually save the record?

Maybe your table structure needs to change. Could you show the table structure? You need to start there.

Change your logic from looking for null to looking for not null and set a flag if one control has a value:

It appears to work for me with this code:

Dim ctl As Control

For Each ctl In Me.Controls
   Select Case ctl.ControlType
       Case acTextBox
           If IsNull(ctl) Then
               With ctl
                   .SetFocus
                   .BackColor = vbYellow
               End With
               MsgBox "Enter Time"
               Exit Sub
            End If
     End Select
Next ctl

I would add this code to the click event of your form that adds the record to the database. Hope this helps....
