Use the InStr() function. It does exactly what you want - it tells you if (and at what position) a string exists within a (larger) string.

You use it like this:
InStr(StartPos, LargeString, StringToFind)

Give 1 as the StartPos for it to search from the begining of the large string. You can use larger numbers to get it to search from mid-way through the large string (to stop it finding things near the start). InStr() gives back the number of characters into LargeString which the first StringToFind appears at (starting searching from StartPos).

If no string is found, InStr() gives 0. So, you could see if InStr(1, YourString, WhatYouWantToFind) gives back 0, and if so, the little string doesn't exist, so you can show the message.
