change your code, like this:


AW
Err_CheckForNullSearch:
    Dim ans as Integer
    ans = -1
    'Entered an item not in the list
    If Err.Number = 2237 Then 
      Err.Clear
      ans = MsgBox("'Entered an item not in the list" & vbCrlF & "Do you wish to continue?", vbYesNo)
      If ans = vbYes then
          Resume Next
      End If
    End If
    
    'If a Null value after the dirty=false then error will occur
    If Err.Number = 3058 Then 
      Err.Clear
      ans = MsgBox("Null value after the dirty=false " & vbCrlF & "Do you wish to continue?", vbYesNo)
      If ans = vbYes then
          Resume Next
      End If
    End If
                        
    'No current record
    If Err.Number = 3021 Then
      Err.Clear  
      ans = MsgBox("No current record" & vbCrlF & "Do you wish to continue?", vbYesNo)
      If ans = vbYes then
          Resume Next
      End If
    End If
 
    If ans = -1 then                   
         ApplicationError Err.Number, Err.Description, "T_F900_GeneralSearch\CheckForNullSearch"

Ok, I know what is going on.  It seems that there are a broad range of Run-Time errors that are NOT 'Trappable' - that is, when they occur, they do NOT trigger the On Error Goto .... error handler mechanism.

If you open the VB6 IDE, and click on Help, then select Index, and enter "Trapping Errors", you will get the 'official' list of Trappable run-time errors.  Non of the errors you are attemting to handle are listed as Trappable Run-Time errors.

What routine is calling your CheckForNullSearch procedure?  The error is probably occuring there.

In addition, there is NOTHING in your procedure CheckForNullSearch which is in ant way related to the 3021 - No Crrent Record condition.  The code in your procedure does not make use of a recordset, or attempting to access data from a recordset.  Thast should be an additional indication that the error you are getting is not being triggered in the procedure where you seem to think it is occurring.
