DTS: Possible to reuse DSN info when creating DTS connection?

Hi,

I'm using DTS to transfer data from Excel etc. to different MS SQL 2000 databases.
To create a new DTS connection to MSSQL you need to specify:
-DataSource(servername)
-Catalog(database name)
- UseTrustedConnection (NT authentication used)
- UserID
- Password
   
All these parameters are already present in my DSN (ODBC or OLEDB), and I only want this information in one place(the DSN). How can I reuse this information (either by telling DTS connection to use DSN or by getting the info from DSN and manually provide them to the DTS connection) ?

Any help would be appriciated.

Regards
Thomas Sorensen

In the DTS designer, choose "Other (ODBC Data Source)" as your destination (instead of "Microsoft OLE DB Provider for SQL Server"). You will then see a choice of existing system and user DSN's and be able to browse for a file DSN. If the username and password are stored in the DSN you should be able to connect using them by just leaving the username and password boxes in the "Choose a destination" dialog empty.

I'm using COM objects to access DTS programmatically, so I need to specify DSN or get info from DSN in my code.

I don't think you can specify a DSN for an SQL DMO connection, but you can find out the specific information if you know the name and type of the DSN.

You can find the DSN information in the following places:
- File DSNs: Directory {$ProgramFilesDir}\Common Files\ODBC\Data Sources\{$DataSourceName}.dsn
  These are simple text-files like an INI file which you can read using standard file IO.
- System DSNs: Registry key HKLM\Software\ODBC\ODBC.INI\{$DataSourceName}
- User DSNs: HKCU\Software\ODBC\ODBC.INI\{$DataSourceName}
  System and User DSNs can be read using standard registry access methods.
