Re: VB6 Raise Error w/ Custom Description being replaced w/ desc f

Tech-Archive recommends: Speed Up your PC by fixing your registry

According to MSDN, user-defined error numbers should start at
vbObjectError+513 (some very old pages incorrectly say '+512')

The vbObjectError constant is not an error code base. It's actually a bit
mask to apply to the user-defined numbers. VB's runtime reserves the first
512 codes as its own.

Is there anything you can think of that differentiates the XP machine
you're
on from other machines where it works? Different language of Windows,
low-level apps & debuggers installed on that one that aren't on the
others,
anything of that nature?

Also, rather than using fixed numbers, you should use the vbObjectError
constant (e.g., Err.Raise vbObjectError + 1, "MySource", "My Custom
Description"), just to be absolutely safe. It doesn't sound like it'll
make
a difference here, but it's worth a try.

Finally, have a look at this article, it sounds awfully similar to what's
happening to you: http://support.microsoft.com/kb/238082/en-us. Of
lesser
relevance, I suspect, there's also
http://support.microsoft.com/kb/255625/en-us.

Mispellings aside, I changed my code to

Err.Raise 550, "MySource", "My Custom Description"

(copied and pasted this time) and I'm still getting the same results. I
got
550 from Help, it's in the user-defined range. The Error Number gets
passed
thru, the custom Description does not.

I'm using VB 6.0, Service Pack 6, on an XP machine.

I'm raising an error with a custom Description in a DLL.

Err.Rasie 106,"MySource","My Custom Description"

When the invoking DLL catches the error the custom description has
been
replaced with the default VB description for the error number I
raised.
And
the Err.Source is blank.

Err.Number = 106
Err.Source = blank
Err.Description = Application-defined or Object-defined error

Any ideas as to why my "custom description" is being lost?


You can't pick just any number as if from a hat.

If you simply read the help entry for the Raise method, you'll see.
