Select All CheckBox

Access 97 ..

I have a continuous form containing a number of records, each of which has a CheckBox linked to a field [fldUpdate].

I also have an update query that updates the records where the above checkbox = True.

How can I add a further checkbox to the form that will act as a 'Select All' box, i.e. when the Select All checkbox is set to True, the checkbox on each record is also set to True - when the Select All checkbox is set to False the checkbox on each record is also set to False.

I have little knowledge of VB, so please comment any code provided.

Hi WebMaker
You can do it in 2 ways:
1) If checkboxMain.Value = -1 then
     DoCmd.runsql "Update Tbla1.checkbox
      SetTbl1.[checkbox] = -1
   end if
   me.requery
2)   (First open a recordset)
    rcrdCount = rst.RecordCount
     rst.movefirst  
         for x = 1 to rcrdCount
           rst.edit
            rst![checkbox] = -1
           rst.move next
         next x
       rst.edit    
    rst.refresh
  me.refresh

Hope it helps

Try this, it works...
Private Sub ww_Click()
  If checkboxMain.Value = -1 Then
    DoCmd.RunSQL "Update tbl1 SET tbl1.checkbox= -1"
   Else
    DoCmd.RunSQL "Update tbl1 SET tbl1.checkbox= 0"
  End If
 Me.Refresh
 End Sub
