Professional Projects
Measurement Studio 8.0 and 8.1 (developed at National Instruments, India): This product is an integrated suite of classes and controls for test, measurement, and automation applications. I was specifically was involved in the design and development of the following controls:

  • Complex Graph .NET Control: This was a new control that was added to the NI Measurement Studio .NET UI controls suite. The control provides APIs to plot complex numbers, along with several customizable UI subcomponents like axes, plots, cursors and annotations. You can find an online demo of some of the features that I developed here and here.

  • ActiveX UI Controls: I was responsible to add new features to the existing ActiveX slew of controls to address the requirements of the Visual Studio 6.0 users.
