Can you stop pulling out exactly the same data from a database, for
example, if you had 2 entries which had the name Chris, it would only
print Chris once? 3 2345

You could use SQL's DISTINCT keyword, but that would only work if every
row in your resultset would be a match.
for instance, given the table
fname | lname
------+------
Chris | Smith
Chris | Jones
SELECT DISTINCT(fname) FROM tblName WHERE fname='Chris' would work, where
SELECT DISTINCT(*) FROM tblName WHERE fname='Chris' wouldn't.
You might be able to do it with some nasty JOINs but those are evil and
kill your performance.
Actualy, if you are using SQL, I would use a LIMIT command as follows
SELECT fname FROM table WHERE fname = Chris LIMIT 1;

I have a text box control on a form, the value of which is calculated

latter setting makes the control completely disappear.
FYI, the form is dialog border style. When set to sizable border style, the
control only appears when the form is re-sized much larger.

Hi
I want to stop a code firing if a certain condition is not met. I only want to allow numeric entries in the textbox to allow the code to run. I tried with the first line of code to stop it, but obviously am failing in my attempt.
If 26 = AlphaNumeric Then Stop
Dim ba26 As String
Dim fileName As String
fileName = App.Path & "\" & "\data\ba26.txt"
ba26 = FreeFile
Open fileName For Output As #ba26

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
