How can cancel a Not on List error in a combo box?

try this

Private Sub Combo178_NotInList(NewData As String, Response As Integer)
   Dim strTmp As String
    DoCmd.setwarning = False

    'Get confirmation that this is not just a spelling error.
    strTmp = "Add '" & NewData & "' as a new Case Type?"
    If MsgBox(strTmp, vbYesNo + vbDefaultButton2 + vbQuestion, "Not in list") = vbYes Then
   
        'Append the NewData as a record in the Categories table.
        strTmp = "INSERT INTO tblSubLookup ( Thetext, TheDropdown) " & _
            "SELECT """ & NewData & """ AS TheText,('Case Type');"
        DBEngine(0)(0).Execute strTmp, dbFailOnError
       
        Else
 
   
        'Notify Access about the new record, so it requeries the combo.
       ' Response = acDataErrAdded
       
         Response = acDataErrContinue

        Exit Sub        
               
    End If

End Sub

or this one

Private Sub Combo178_NotInList(NewData As String, Response As Integer)
   Dim strTmp As String
    DoCmd.setwarning = False

    'Get confirmation that this is not just a spelling error.
    strTmp = "Add '" & NewData & "' as a new Case Type?"
    If MsgBox(strTmp, vbYesNo + vbDefaultButton2 + vbQuestion, "Not in list") = vbYes Then
   
        'Append the NewData as a record in the Categories table.
        strTmp = "INSERT INTO tblSubLookup ( Thetext, TheDropdown) " & _
            "SELECT """ & NewData & """ AS TheText,('Case Type');"
        DBEngine(0)(0).Execute strTmp, dbFailOnError
       
        Else
 
   
        'Notify Access about the new record, so it requeries the combo.
       ' Response = acDataErrAdded

        me.Combo178=""
         Response = acDataErrContinue

        Exit Sub        
               
    End If

End Sub

this is not correct
      DoCmd.setwarning = False

it should be  

       DoCmd.setwarnings  False

also, if you set this
 DoCmd.setwarnings  False


you must trun that to true after using it

 DoCmd.setwarnings  true

in your codes you really don't need it

Private Sub Combo178_NotInList(NewData As String, Response As Integer)
   Dim strTmp As String


    'Get confirmation that this is not just a spelling error.
    strTmp = "Add '" & NewData & "' as a new Case Type?"
    If MsgBox(strTmp, vbYesNo + vbDefaultButton2 + vbQuestion, "Not in list") = vbYes Then
   
        'Append the NewData as a record in the Categories table.
        strTmp = "INSERT INTO tblSubLookup ( Thetext, TheDropdown) " & _
            "SELECT """ & NewData & """ AS TheText,('Case Type');"
        DBEngine(0)(0).Execute strTmp, dbFailOnError
       
        Else
 
   
        'Notify Access about the new record, so it requeries the combo.
       ' Response = acDataErrAdded

        me.Combo178=""
         Response = acDataErrContinue

        Exit Sub        
               
    End If

End Sub

No luck I tried everything.

You need to include a second response OUTSIDE the If block for your MsgBox:

If MsgBox(strTmp, vbYesNo + vbDefaultButton2 + vbQuestion, "Not in list") = vbYes Then
  <your code here>
   
   Exit Sub        
   
Else
  Response = acDataErrContinue            
End If

Also, you really don't need the "SELECT" in your insert statement. It can be written like this:

strTmp = "INSERT INTO tblSubLookup (Thetext, TheDropdown) VALUES('" & NewData & "', 'Case Type')"

<No luck I tried everything. >

what exactly do you mean?

this is the problem you posted
   <If I cancel I keep getting promt with the not on list error form access. How can I click cancel on adding to lookup tale and move on?>

and the codes i revised prevents the error.

Exactly what do you mean by "Cancel"? Your MsgBox shows Yes and No buttons. Do you mean you get this error when you click "No", or do you get it when you do something else?

Note also that my suggestion is the same as Cap's - i.e. including the acDataErrContinue in the Else section of your IF msgBox block. I just couldn't read it, with the indentations of the code block. Only change I'd make would be to remove the "Exit Sub" from that block, since it's meaningless (and could cause unexpected results). Your logic flow will take you to the End Sub statement eventually, so unless you have a specific reason to use "Exit Sub", it's best to remove it.

The error I receive after clicking NO is the following. "The text you entered isn't an item in the list" "Select an item in the list or select an item in the list. I think it is because the the limit to list property is yes. If I select no on this property the not in list event will not fire.

If you set a Breakpoint on this line:

Response = acDataErrcontinue

Do you actually get to that line?

You might also try commenting out this line:

me.Combo178=""

or replace it with this:

Me.Combo178.Undo

seanlhall,

post the codes that YOU are using..

Here is a test file. It will produce the same error. open frmsubject. NotinList.mdb

If you want to type in a case type that you dont want to save in the lookup table it is not possible.

When I type something that is not on the list, i get the popup to add it or not. If I chose no it clears the box. I want to click no and move on storing the value in the control source case status and not store it in the lookup table.

then why not just set the limit to list property to NO.

I am going to use what you sent. If the user does not like what they have added to the lookup table they can just remove it later. Clearing the combo forces them to select a value from the list or adding on to it with out getting the error. Thanks.

If I did that the Not on List Event does no work.
