Hi,
I'm testing ODBC connection using VB.NET 2008.
Fisrt I have created, with ODBC manager, an User ODBC connection named 'XXX' that works fine (all test passed).

In my program I set the ConnectionString so: myODBC.Connectionstring="ODBC=XXX;"
when I try to open the connection VB goes in error :

SQL Error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
SQL Scriptline:
SQL State:IM002

I'm confused what is the mistake?

Thanks

additional information copied from non-solution below
At last I looked in the system registry (HKEY_CURRENT_USER\Software\ODBC\ODBC.Ini\XXX)
and the data are valid the name of the ODBC is the right one , I did the test with both a System DNS , but I have same result.
I'm working on PC where is installed XPPro 32bit.
The DNS appears under User DNS

Seems the DSN is not created properly. Can you go to Run> then paste odbcad32.exe
Can you see your ODBC connection there. If yes, under which tab?

Can you test the connection there if it is connecting (this step is not needed for you if the ODBC name is there)

The connection string "ODBC=XXX" is not valid. It should be "DSN=XXX".

If your data source requires credentials, you will need to specify those as well: "DSN=XXX;Uid=username;Pwd=password".
