Greetings,

I have the following problem.

I am doing the following

To add a Data Source to the VS 2005 for an Access database, you can:

a. From the Data Menu, click on Add New Data Source

b. Choose Database and press Next

c. Select New Connection

d. Under Data source, press the Change button and select Microsoft Access Database File. Press OK

e. Under Database file name, press the browse button and select your file.

f. Press the TEST CONNECTION button. The connection test should succeed. Close that dialog and press OK.

g. From the "Choose Your Data Connection" screen, press NEXT.

h. You will now be presented with a pop up asking if you want VS to copy the file to your project. If you click NO it will leave it in it's current location, and if you click YES it will copy the file to your project location.

i. Expand the Tables tree view.

j. Check your tables that you want included.

l. Click Finish
which worked normaly quit well. But since a fwe days I have the following problem.

After adding the acccess db via the way above the dataconnection and the use of the DataGridView is working as long as I am in the DevelopmentEnvironment. As soon i start the application i get the following message

exception
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

and the stack trace
bei System.Data.Odbc.OdbcConnection.HandleError(OdbcHa ndle hrHandle, RetCode retcode)
