    As above.

    For example, if I wanted to find "hi" inside "lorem ipsum hi amet". I know ASP.Net has a function for this - Contains().

    Thanks in advance.

    Hello,

    Following is an example:
    
Dim SearchString, SearchChar, MyPos
SearchString ="XXpXXpXXPXXP"   ' String to search in.
SearchChar = "P"   ' Search for "P".
MyPos = InstrRev(SearchString, SearchChar, 10, 0)   ' A binary comparison starting at position 10. Returns 9.
MyPos = InstrRev(SearchString, SearchChar, -1, 1)   ' A textual comparison starting at the last position. Returns 12.
MyPos = InstrRev(SearchString, SearchChar, 8)   ' Comparison is binary by default (last argument is omitted). Returns 0.
    Code (markup):
    You can also used InStrRev Function
    Returns the position of an occurrence of one string within another, from the end of string.
