Ananda,
Yes, it is possible to use the 6527 in VB 6.0 without Measurement Studio. The best starting point is to look at the examples shipped with the Traditional DAQ drivers. They should have installed to the following directory:
C:\Program Files\National Instruments\NI-DAQ\Examples\VBasic
If this directory does not exist, it probably means that Visual Basic support was not selected when you first installed your Traditional drivers. To install these examples, reinstall the Traditional drivers and make sure that "Microsoft Visual Basic Support" has been selected to install on the Features menu.
If you can't find what you're looking for in the shipping examples, try searching the online
Example Code Library. There are a lot of good examples out there written by both NI customers and engineers.
Hope this helps!
