The Windows Software Development Kit (SDK) provides you with the headers and the libraries so that you can call the windows api functions from cvi. It also installs the help files for the SDK.
NI Measurement Studio actaully provides activex controls and class libraries that can be used with Visual Studio 6. This usually includes Visual Basic and Visual C++ 6.0. Measurement Studio includes user interface controls that you can drop down on your forms and other activex controls that let you program National Instrument data aquisition devices (CWDAQ is the name of the control) and also let you do instrument control thru GPIB or serial(CWGPIB and CWVISA).
You dont need a seperate license for distributing your CVI application, just for the development system. There
are exceptions to this ofcourse, like the CVI SQL Toolkit. For the list of these exceptions, check out section 12b at the following link
http://www.ni.com/legal/license/
But if you are not using just the tools that come with CVI FDS, you wont need a seperate license for each distribution kit you create. If you are planning to use the other toolkits, I would recommend calling in at 1-800-433-3488 and asking to talk to your internal sales representative for more information.
I hope this helps
