hi,

i was wondering if there were any guides/examples for getting started
with DSO in C#. i'm new to both DSO and C# (coming from C++ and java --
no COM). i've tried using tlbimp, but i run across the following error:

$ TlbImp "c:\Program Files\Common Files\Microsoft Shared\DSO\msmddo.dll"
/out:Microsoft.SQLServer.DSO.dll
Microsoft (R) .NET Framework Type Library to Assembly Converter 1.1.4322.573
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.

TlbImp warning: Type library importer has encountered an interface not
derived from IUnknown: _HiddenInterface.
Type library imported to c:\temp\dts\Microsoft.SQLServer.DSO.dll

is this the wrong DLL to attempt to wrap?

does anyone have pointers to working skeleton C# code for using DSO,
including how to create the RCW for the appropriate DSO dll?

thanks!

actually, i don't see that error message when i tlbimp msmddo80.dll --
is it adequate to reference the RCW for this specific version of the
DLL? what's the general rule for stuff like this?

my simple test code (just getting the server name and version) seems to
work, at least. =)

looks like this error message happens the first time i tlbimp either
msmddo80.dll or msmddo.dll, but not the second. any idea why that might
be happening? anyway, anyone have a pointer to how to get started with DSO?

thanks!
