Hi pamxy – when you say “build up”… do you mean create one? So you want to write a TWAIN driver?

A .ds file is a just .dll that has been renamed to .ds.

“DS” stands for Data Source, which is what TWAIN drivers are officially called, for reasons which I have forgotten.

A Data Source DLL is created by following the specifications given in the TWAIN Specification, which you can download here:

On that same page is a link to a “Sample Data Source and Application” – this includes source code for a TWAIN driver.
There’s also a C++ framework for a TWAIN driver here:

note that this is officially unsupported code, but it has been used to write several commercial TWAIN drivers:
