AFAIK, the ODBC driver is simply a Windows DLL with some standard exported
functions.

Ahh, an ODBC driver is not an OLE/COM object, it is a dll. You need to
find odbc*.ini

That is either in the DLL or in another DLL, I forget.

That's the job of the ODBC driver. (That's what you are writing)

The user opens a registered data source. The ODBC layer loads and
initializes the DLL. All the SQL calls to that connection go to that DLL.

Huh?

It's only software, so the answer is always yes, but the degree of
difficulty is the point. C# should be able to do ODBC.

C# is crap anyway, it is a bogus ripoff of Java. Use C or C++.

Get MSDN if you need that info. In fact, it sounds like you are trying to
make a Windows program, judging from the questions you are asking, I'd say
you need MSDN.

Get MSDN.

There are so many variables that can affect this that a simple sentence
saying you have a problem gives anyone interested in helping you nothing
to work with.

Step (1) Get a Windows development environment if you want to develop for
WIndows.

Step (2) It sounds like you don't really understand Windows or don't have
access to documentation, so get MSDN and read.

Step (3) Somewhere, I recall seeing a text file based ODBC sample driver.
It is *everything* you need to create a working ODBC driver. Just gut the
framework and fill it in with the code for your system.

Alternative:
Hire a consultant that has this stuff already.
