Remarks
You can use the AccessError method to return the descriptive string associated with a Microsoft Access or DAO error when the error hasn't actually occurred, but you cannot use it for ADO errors.
You can use the Visual Basic Raise method to raise a Visual Basic error. Once you've raised the error, you can determine its associated descriptive string by reading the Description property of the Err object.
You can't use the Raise method to raise a Microsoft Access or DAO error. However, you can use the AccessError method to return the descriptive string associated with these errors, without having to generate the error.
You can use the AccessError method to return a descriptive string from within a form's Error event.
If the Microsoft Access error has occurred, you can return the descriptive string by using either the AccessError method or the Description property of the Visual Basic Err object.
Example
The following function returns an error string for any valid error number:
Note
You must have your error trapping options set to Break on Unhandled Errors for the code to run in the VBA IDE. You can set this option on the General tab of the Options dialog found on the VBA Tools menu.
Function ErrorString(ByVal lngError As Long) As String
Const conAppError = "Application-defined or " & _
"object-defined error"
On Error Resume Next
Err.Raise lngError
If Err.Description = conAppError Then
ErrorString = AccessError(lngError)
ElseIf Err.Description = vbNullString Then
MsgBox "No error string associated with this number."
Else
ErrorString = Err.Description
End If
End Function
