Although I don't spend too much time wondering what other programmers think of me or the language I choose for developing in, I have encountered similar circumstances. People who work in C/C++ tend to have that disposition, Eugen. They are equally, if not more, critical of VB programmers. Their assertions are based on the idea that C/C++ requires you to build most aspects of your program from the 'ground up'. However, ask them what headers they use? Did they make the header or are they using something someone else did? Also, one of the great strengths of LabVIEW is that it is easy to make cross-platform applications. How often do they even attempt that in C/C++? When they do how much extra work is that?
There are definitely advantages to using C/C++ over LabVIEW. For example, the ability to make Win API calls that return STRUCT data types. LabVIEW will not always work with these data types (especially STRUCT data types that contain other STRUCT data types). However, the ease of development and handy tools to make development swift and reliable far exceed, in my opinion, other shortcomings.
