Hi:
Thank you for contacting National Instruments.
Yes, you can measure the temperature of the room using Visual C++ without Measurement Studio. However, you will not have access to the powerful data analysis algorithms, scientific user interface controls & graphs and easy to use networking features that ship with Measurement Studio.
Using Measurement Studio will increase productivity and make DAQ programming easier.
If you have additional questions, please do not hesitate to contact me.
Regards,
