trouble with web forms

S

somersbar

im trying to get a table from a microsoft access database on a simple
web form using visual basic.net. ive set up the database as a file
dsn.

this is my connection string:

DBQ=C:\Program Files\Microsoft
Office\OFFICE11\SAMPLES\Northwind.mdb;DefaultDir=C:\Program
Files\Microsoft Office\OFFICE11\SAMPLES;Driver={Microsoft Access Driver
(*.mdb)};DriverId=25;FIL=MS Access;FILEDSN=C:\Program Files\Common
Files\ODBC\Data
Sources\test2.dsn;MaxBufferSize=2048;MaxScanRows=8;PageTimeout=5;SafeTransactions=0;Threads=3;UID=admin;UserCommitSync=Yes;


works fine when i try it with a windows form, however with the webform,
when i try it, i get the following errors because of line69 :

Well, I could be wrong since I haven't seen every detail of your setup or
code, but that looks like a very strange connection string. Here are some
things I would check:

1. Directories rarely start with the drive letter (C:) when dealing with the
web.
2. Your connection string looks much more complicated than necessary. Here
is the line that I use to create my connections in all the websites I have
created that use Access databases (and they have been on different servers,
so unless you have a strange setup I'm guessing it will work for you too):

Dim myconnection As New
OleDbConnection("PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=" &
Server.MapPath("/mydatabase.mdb"))

Just modify the last part to be the correct path to your *.mdb file.

3. Check the permissions on the *.mdb file to make sure ASPNET has
permission to access it.

Although something that I am kind of getting the impression of is that you
require a more full-featured and secure database, Access was not really
intended for web-related stuff. If you have a very big company or plan to
use the database heavily, I would put in the effort and money to buy either
Oracle or SQL Server (you would probably prefer SQL Server since you are
coming from Access). I am only a student, but ASP.NET and Web Development
are my areas of concentration and these are things I have been taught and
gained through experience and articles I have read. Good Luck!
