[AccessD] Error Code Generator

"Why is it better to embed the error routine in the particular proc or
func". Lot's of reasons, not least of which is:

Because the person who codes a proc/func is in the best position to
determine what action should be taken with which specific error codes, and
it only makes sense the do this in the routine that errored - for one thing
the error handler will have access to all the local variables and parameters
that the routine uses.

Because to write a routine that would know what to do with all x thousand
errors in any code that any programmer ever wrote in any application would
be up for the psychic coder of the century award. :-)

I didn't write it, but it raises a question that I have wondered about for a
while. Why is it better to embed the error routine in the particular proc or
func than to write one global error handler and pass it the text and perhaps
the proc/func name, so there's only one error handler in the whole app? I
never did understand this. Can anyone provide some insight?

I believe someone on the list created an error generator. I believe it might
be JC? Anyway I have been using it a lot for code examples and just to be
politically correct want the owner to know. Example below
 
 
Function CopytoWss()
On Error GoTo Err_CopytoWss
    DoCmd.SelectObject acTable, "Contacts"
    DoCmd.RunCommand acCmdExportSharePointList
Exit_CopytoWss:
Exit Function
Err_CopytoWss:
        MsgBox Err.Description, , "Error in Function CopytoWss"
        Resume Exit_CopytoWss
    Resume 0    '.FOR TROUBLESHOOTING
End Function
