I've got a text field that I want to use as the primary key, but it has to be case sensitive.  That is, it has to allow for three recordes with key fields:
fred
Fred
FRED

How do you tweak the index to do this?

In the onUpdate event write this code:

MyField=Ucase([MyField])

then you obtain only FRED

The only way will be to add a "hidden" key and transform the original field into it's ASCII values.
You could use a function like:

Function fncASCII(strInput As String) As String
Dim intI As Integer

For intI = 1 To Len(strInput)
fncASCII = fncASCII & Right("000" & Asc(Mid(strInput,intI, 1)), 3)
Next intI

End Function

Clear ?

Thanks Nico.  The answer is clear enough, although it isn't what I wanted to hear.

Are you in my time zone (gmt +2), or are you a night owl?

I wanted to input directly to the table without a form and without code.

That's not possible with access, but when you also have MS SQL then you could create a table with a StoredProcedure that performs a function like this automatically when inserting/updating a row.
