How do I access specific character locations within strings? I know in C++
you can access them using brackets (i.e. string[1]), but I can't figure it
out for VB.

To illustrate, for the example string "...Clamp 0.2", I am trying to find
the position of the last period in a series of periods. I tried using
"InStrRev," but that gave me a false positive by reporting the period in
"0.2". The series of periods designates a level within a tree structure, so
its position is very important. Is there any way I can use "InStr" or
"StrComp" or something with this. I need it to be very fast as there are
35,000 lines to process.

Thanks,
