error handler in every method. You only really need to add an error handler in every event handler. E.g. Every click event,load event, etc share|improve this answer answered Sep 15 '08 at 17:45 Darrel Miller 85.9k17131196 But, what about a normal method in a class,which may be doing some calculation,and throw an overflow error? –ravi Sep 15 '08 at 17:52 1 In a VB6 application, once you show a form, all interaction with that application has some event handler at the top of the call stack and as Brad Richards says, errors propagate upwards. The only non-event handler than needs a handler is Sub Main. –Darrel Miller Sep 15 '08 at 18:13 add a comment| up vote 2 down vote While errors do propogate upwards, VB6 has no way to do a stack trace, so you never know which method raised the error. Unfortunately, if you need this information, you have to add a handler to each method just to log where you were. share|improve this answer answered Sep 15 '08 at 23:06 Mike Dimmick 7,89411537 add a comment| up vote 1 down vote Also: errors do propagate upwards: if method X calls methods Y and Z, a single error handler in method X will cover all three methods. share|improve this answer answered Sep 15 '08 at 17:59 Brad Richards 5781516 add a comment| up vote 0 down vote I discovered this tool yesterday: http://www.everythingaccess.com/simplyvba-global-error-handler.htm It is a commercial product that enables global error handling in VB6 and VBA

Option Explicit Private Sub Form_Load() On Error GoTo Form_LoadError Dim ErrorResult As Integer ErrorResult = 1 / vb6 on error 0 Exit Sub Form_LoadError: ErrorWriter "Form_Load", Err End Sub Public Sub ErrorWriter(SubFunName As String, E As ErrObject) Dim ErrorNumber As Long, ErrorDescription As String Dim ErrorHelpContext As String, ErrorHelpFile As String Dim ErrorLastDllError As String, ErrorSource As String Dim FName As String, FNumb As Integer, ErrorMessageString As String ErrorNumber = E.Number ErrorDescription = E.Description ErrorHelpContext = E.HelpContext ErrorHelpFile = E.HelpFile ErrorLastDllError = E.LastDllError ErrorSource = E.Source On Error GoTo ErrorWriterError 'this resets the error object so that is why we collect above FNumb = FreeFile FName = App.Path & "\" & App.EXEName & "_ErrorLog.txt" ErrorMessageString = App.EXEName & "," & SubFunName & "," & ErrorNumber & "," & ErrorDescription & _ ErrorHelpContext & "," & ErrorHelpFile & "," & ErrorLastDllError & "," & ErrorSource Open FName For Append As #FNumb Print #FNumb, ErrorMessageString Close #FNumb Exit Sub ErrorWriterError: MsgBox "Unable To Write Error to file! " & ErrorMessageString, vbOKOnly + vbCritical, "Error" End Sub but that does nothing to handle the actual error where it happened which is always the best bet. The above is mainly for logging errors.
