Returning the Err object from a function

Hi! :)

I want to return the err object from a function. How do I do this?

Do I have to create my own error class or is there a way to create an
instance/copy of the existing to return?

Thanks a million! :)

the ERR object has a global scope, so results are available outside of
your function. What are you trying to accomplish?

Hi Dan! :)

I use "On Error Goto 0" after the call to the function that might fail. This
clears Err automatically. I only use "On Error Resume Next" when theres a
function that I don't have control over. I want to get all other errors.
This means that I need to save the error message manually before the "On
Error Goto 0". Rather an error message than a script that doesn't function
as is should and me thinking it does.

I'm also doing other things between I'm getting the error and I want to
print the error message. I'm really just interested in Err.Number and
Err.Description. They are the ones I intend to put in my own little error
class if I don't get an answer. I just thought there might be a way to use
the existing class. :)

Thanks! :)

Hi,

You can use the Raise method of the error object to raise your own error. I
believe the syntax is:

Err.Raise(intNumber, "your source", "your description")

where intNumber is your error number. The error condition is maintained
until:

Err.Clear
On Error GoTo 0
On Error Resume Next

or a new error is raised.

Awhile ago I posted some demo code (Topic "Error handling bug on GetObject?");
perhaps this could you give some hints.

complete list of params according to the VBScript Docs:
object.Raise(number, source, description, helpfile, helpcontext)
(all params except number are optional)

the correct call would be:
object.Raise number, source, description, helpfile, helpcontext
NO param list () in VBScript Sub calls!

I found the topic at:
http://www.tutorialsall.com/VBSCRIPT/Error-handling-193562/.

From here: "21: saveErr = Array( Err.Number, Err.Source,
Err.Description )"
Are you suggesting that I put Err in an array?
If you read a few rows up you see that I intend to make my own small error
class (not more than a simple struct) if what I'm asking for help about
can't be done.

It's not very nice to send people to read that much without reading their
question first. Thanks anyway! :)

I'm not interested in raising errors. :)

I also (as Richard's example) use paranteses around the arguments. I think
it makes the code easier to read. You have to live with writing Call before
the function/sub name but I prefer it to no paranteses anyway. :)
