Hi Scott,
Not a problem, I'm going to play with it this week and see what I can
come up with.
You are dead right. It definitely should return socket error and
SetLastError(WSA_INVALID_PARAMETER). That might cause winsock to give
the resource not found error if we return the wrong error. I'll let you
know what I find.
Cheers,
Sam

Subject: Re: Winsock namespace provider problem
Hey Sam. That is puzzling...and I'm not really sure why Windows is
returning 1813 (ERROR_RESOURCE_TYPE_NOT_FOUND). One thing that is a
little suspect with the NSP code however is how errors are being
returned in some of the unimplemented functions.
NSPInstallServiceClass just returns WSA_INVALID_PARAMETER. However, if
memory serves correctly, one is supposed to return SOCKET_ERROR and set
the specific error with SetLastError. Any chance you could make this
change in the NSP source code, reinstall it, and see if anything
changes?
Also...the NSP is self-registering...you don't need NSPTool. Just use
regsvr32 on the dll to install/remove it.
Take care,
Scott
