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

Inputs
RevInStr(String1 As String, String2 As String)

Assumes
Example: let positon = RevInStr("Http://www.mypage.com/","/") In this case position would be 22, not 1

Returns
The Integer returned is the postion of the String 2 in String 1.

API Declarations

    Let pos = (InStr(pos2, String1, String2))
    Let pos2 = pos2 - 1
