If you're looking to use IVI drivers in Measurement Studio, you have some options:
1) Measurement Studio's Add/Remove Class Library Wizard allows you to include instrument drivers in your project. If you create a new Measurement Studio C++ project, you should be able to select instrument drivers in the Add/Remove Class Library Wizard window under the "Legacy C and IVI C Drivers" node. This adds the header and lib or source files for the driver to your project. You can then use the driver just as you would in CVI.
2) The IVI Class Drivers from National Instruments (part of the NI IVI Compliance Package) include Measurement Studio C++ API's. Again, you can add them to your project by selecting them from the Add/Remove Class Library Wizard. The C++ API's also include full documentation, which is integrated into the Measurement Studio help.
