John,

I should have added that you should become familiar with the InStr and
InStrRev functions, which are VB/VBA's equivalent of C's strstr function.
InStr searches left-to-right and InStrRev searches right-to-left. Both
return the 1-based offset (always from the left) of the first character of
the search-for string within the search-in string. Both return 0 if the
seach-for string is not found.

VB/VBA also has a StrComp function which is essentially the same as C's
strcmp function, except that you can specify whether the comparison it
case-sensitive or case-insensitive.

John,

To get a single character, use Mid. E.g,.

Dim C As String
C = Mid("abcdefg", 5, 1)

will put "e" in C (5th character, length 1)/

I'm used to strings
being arrays of characters so this seems mad!

Strings in VB/VBA are actually what are called BSTRs, and part of
COM/OLE/Automation. See
http://msdn2.microsoft.com/en-us/library/ms221069.aspx

You can treat them as if they were arrays of characters. You can't use
pointers as you do in C/C++. Instead of a point to a character, you use an
1-based index into the string.

I wanted to read along a string character by character in VB and ended up
with a home made function :-

Public Function GetChr(ByVal InPutStr As String, ByVal position As
Integer)
As String

If position <= Len(InPutStr) Then
GetChr = Right(Left(InPutStr, position), 1)
Else
GetChr = Chr(0)
End If

End Function

Is there an easier (and more efficient) way than this. I'm used to
strings
being arrays of characters so this seems mad!
