OleDB for MS Access - Help!

[Dave Martin]

I am working on a project that is giving me trouble. It
has to be done quickly. It is being written in C# and I
am totally new to C#.

I need to update an MS Access database application that
was created by a third party developer that is no longer
in business. In other words there is no one there I can
turn to for help.

My first set of code gave me every indication of having
updated the data table successfully -- even returning a 1
to show that one row was updated. But when I went to the
table to verify, no changes had taken place.

I assumed that this was security related -- that "whoever"
the system thinks the program *is* does not have rights to
make the change.

So I tried to add security parameters to the connection
string. But then I got the error message: "could not find
an installable ISAM".

A net search convinced me that maybe my syntax was wrong,
so I tried to build a connection string by letting Win
2000 do it (create file.udl, left click, select
properties:provider,select MS Provider for ODBC
services...). The result of using this new cs was the
same message.

I am stuck. Do I have a version problem with my OleDB
drivers? Is my syntax still wrong?

Here is the system-built connection string with uid/pw
removed:

Provider=MSDASQL.1;Password=xxxxxxxx;Persist Security
Info=True;User ID=xxxxxxx;Extended Properties="DSN=Access
Files;DBQ=I:\IMS\Data\ImsData.mdb;DefaultDir=I:\IM S\Data;Dr
iver=odbcjt32.dll;DriverId=281;FIL=MS
Access;MaxBufferSize=2048;PageTimeout=5;PWD=xxxx;U ID=admin;
"

Note: I removed the outer level server login arguments in
the version I inserted into the app, because the final
connection string is used on the server itself and does
not need it. The Access uid and pw were retained.

Thank you

I am working on a project that is giving me trouble. It I would use ADO.net. Make sure you have MDAC loaded on the box.
