How to convert error code to text??

[**Developer**]

For WinSpool.SetPrinter a zero return indicates an error.

SetLastError defaults to True in VB so I can get the errorcode as follows:

ErrorCode = Marshal.GetLastWin32Error()

The value is 6 but that tells me very little.

Where can I find some text to better describe the error??





Thanks

Manually, run "net helpmsg 6" in a console window, or run the Visual
C++ error lookup utility (can be installed with VS).

Programatically:

Dim e As New Win32Exception
errmsg = e.Message

Maybe I'm not doing it correctly

I pasted net helpmsg 6 after the prompt> in the Command Window and
hit CR and got:
Command "net" is not valid.

On my Windows XP Professional SP2 machine:

C:\...>net helpmsg 6

Das Handle ist ungültig.


C:\...>

I'm probably doing something wrong.
Is that realy the way to do it?
Do I need to install something special?
Do I need to find the directory Net is in an give the full path?

Thanks

Mhm... I simply started "cmd" and entered the command. The directory
doesn't matter.

Well I couldn't get it to work so I tried Help and that worked. Got as far
as using immed and >cmd and will probably get net to work eventually - but
not yet. No big deal - I used your


\\\
Dim s As String = _
(New Win32Exception(Marshal.GetLastWin32Error())).Message
///

works great

Thanks

PS

After the > prompt I type
net helpmsg 6
and get
Command "net" is not valid
