Passing Array of Strings Between ViB and C

[Niya]

(in this case there'd be a lot of things one can do with regards to fast string-processing directly in VB6,
which will perhaps beat what you currently have in VC++)

Generally speaking there's not a chance in hell. In her case though you may be right since she is still dealing with BSTRs on the C++ side but you can write string processing functions in C++ that is faster by great magnitudes than even the best VB6 equivalent. I once wrote a parser in VB6 which I needed to parse large texts on every keystroke in order to facilitate a VB-like IDE. When I loaded a file of a size like a 100 KBs or so, the IDE would slow down tremendously. I mean like every keystroke would cause something like a 6 second delay. I re-wrote the parser in C++ and exported it through functions and it could now process texts well up to 500 KBs in milliseconds. The problem with string processing in VB6 is immutability. This limits efficiency.
