I wrote a Software Defined Radio in VB6 + Delphi + Assembler back in 2003, and it's still in use today - I still see downloads - https://www.g8jcf.uk/. The Delphi & Assembler were used to write the low level DSP and vector arithmetic - it was developed on a Celeron 333 with 192 MBytes of RAM a SONY VAIO laptop !!! The G8JCFSDR is a hobby program for free for a relatively small base, so it's not worthwhile me porting it to C#, although it might be an interesting excercise. Back in 2003, so much stuff had to be added around VB6 to hook message events, handle callbacks, etc, so it might be much easier/quicker today Ah those were the days :-) 73 Peter - GM8JCF

Take a look at Sandboxie which enables one to run any program, but especially browsers in a sandbox.
