This code will return every charecter of a string, one at a time in sChar variable.

Let me know if I am off base.

I need sChar to be a byte or a long, not a string.  Is this possible?

It is not a problem to change sChar to a long, as long as the data in the string is numeric.  However, if the data is numeric and you are looking at one charecter at a time it would make more sense to use an integer.  It will take up less memory.

A Byte will work as well, and would probably be the best to use because of memory allocation.

The data is definitely non numeric.  What I really need is the ascii value of every character in the string be it a number or letter.

This should do it...

Dim bChar As Byte

For x = 1 To Len(sstring)
   bChar = Asc(Mid(sstring, x, 1))
Next

Dim sString

sString = "Hello World"

For x = 1 To Len(sString)
   Debug.Print Asc(Mid(sString, x, 1))
Next

Thanks, you saved my life.  

You know as easy as VB makes working with COM components and stuff it makes this kind of problem equally hard.  At least for a recent convert from C++.
