Hmmm...
trying to find a solution a little bit difficult in that case. I have never used visual basic or visual c before. Maybe there is a function for exporting libraries, or a "place" in the settings where the paths to the libraries are saved. So you could find out where the library is located, or if it's probably an
ActiveX control.
ActiveX controls can be imported via "component->import
activex control" in delphi.
