Error handling: Add new records (incomplete record / incorrect data)

[robtyketto]

Greetings,

I added my error checking (see code below) on the Form "On Current" event as
I believe this code will run upon any action on screen being actioned.

Errors happen when users are adding incomplete/incorrect data then pressing
the next navigation button which adds a record if it is the last record.

Where is best to put my error validation?
Thanks Rob

Private Sub Form_Current()
 
On Error GoTo MyErr
 
ExtenuatingCount = DCount("[StudentID]", "tblStudentsResultsDelivery", 
"[StudentId]= '" & [txtStudentId] & "' AND [ExtenuatingCircumstances] = 
True")
 
If ExtenuatingCount > 0 Then
    Me.lblExtenuating.Visible = True
Else
    Me.lblExtenuating.Visible = False
End If
 
MyExit:
  Exit Sub
 
MyErr:
    MsgBox "Please check all information is correct and present", 
vbExclamation
    Me.txtStudentId.SetFocus
 
Resume MyExit
 
End Sub

Hi, Rob.

I guess under "error checking" you mean trapping faults (particulary index/constraint violation) when form saves a record into a linked table.
If so, then use Form_Error event to handle the situation.

Cheers, thank for the advice.

Will get researching that now !!

I put some code in there, but when I try to add records where data is incomplete or junk I get error 2105 (cant move to next record).

My error handling did nothing !

I dont want to write code for every single item on the screen.

Anyone offer any tips or advice?

Copied code below, cheers Rob

Private Sub Form_Error(DataErr As Integer, Response As Integer)
 
On Error GoTo MyErr
 
MyExit:
  Exit Sub
 
MyErr:
    MsgBox "Please check all information is correct and present", vbExclamation
    Me.txtStudentId.SetFocus
 
Resume MyExit
 
End Sub

Ok.

Lets clarify some things.

• Once more. Do the changes you make in a record violate linked table rules (indexes, validation rules)?
• Does the event handler ever run?
• Do you use form navigation bar to move to a new record or you use custom buttons or whatever other involving VBA code? If so post the code.

Oh, sorry. Didn't pay attention to the code. You just need to realize the difference between On Error statement which allows to handle errors raised by code and Form_Error handler which is fired when form fails to perform some action (e.g. save record). Your code should look like the following:

Private Sub Form_Error(DataErr As Integer, Response As Integer)
    MsgBox "Please check all information is correct and present", vbExclamation
    Me.txtStudentId.SetFocus
    Response = acDataErrContinue  'suppress Access error dialog 
End Sub
