Hi all,

I have made many applications using Delphi 6.0, Delphi 7.0, MS VS.Net
2003, MS VS.Net 2005 and MS Access 2000 - 2003. But all of my
applications have following error on some computers (machines).

The error message: MS Jet Database Engine could not find the column
'colText'

I have this problem for two years. But I can't stop this error
occurring, however I've done everything I can.
I quess that OS (Windows XP with SP2) of those computers have
corrupted MS Jet Database Engines and the MS JET is core object of
this problem but not MS Access, Programming languages and Programing
tools.
Also, I have known that MS Jet can't find the column that is the first
not numeric column of a table.

for example:
Table 'tTable1' has 3 columns. Column 'id' is autonumber and primary
key. Other 2 columns' types are Text(50).
When I execute a query "SELECT id, colText, colText2 FROM tTable1"
then the error occurs on column 'colText'.
If I change the query to "SELECT id, colText2, colText FROM tTable1"
then the error occurs on column 'colText2'.
In all cases of the query, the column 'id' is out of the error.

Help me guys !!!!!!
Any suggestion will be highly appreciated.
