Test was done for 5 same applications written in different widget library. Only one form application was created without any additional stuff. Mainly the memory consumption will be much bigger for real applications.

 

Two criteria was considered:

   1, speed of application           - the speed of Visual Basic is worst.

   2, memory consumption         - the memory requirements of .NET are worst.

 

The usability range is from 0 (worst)  to 10 (best). It was rated according to my subjective feeling.

            RAD MSVC was classified 0 because of bugs
