RevInStr


Visual Basic 6 has a new function called InStrRev, which searches a string from right to left. I found it very usefeul, so much so that a project of mine relies completely on it. When I tried to work on the project at another location on VB5 I found that the function did not exist. So, I wrote it.
I left out the compare method, you can add it if you want

Original Author: Shane Presley

    Let pos = (InStr(pos2, String1, String2))
    Let pos2 = pos2 - 1
  Loop Until pos > 0 Or pos2 = 0
