Resolution Of Following Error: IM010: [Microsoft][ODBC Driver Manager] Data Source Name Too Long

Hi SQL Server Team,

In order to add a data source by using ODBC Administrator, programmatically i am using SQLConfigDataSource. Thus calling SQLConfigDataSource with the fOption set to either ODBC_ADD_DSN for creating a new DSN.

Following is the stattement specified in the source code. where type_of_driver = "Microsoft Access Driver (*.mdb)"; and parameters contains the data source source credentials information such as DSN, UID, PSW, FIL, Description, DataDirectory,DEFAULTDIR and DBQ all separated by "".

rc = SQLConfigDataSource(NULL, ODBC_ADD_DSN, type_of_driver, parameters);

after execution of below mentioned command an error is encountered i.e -1 is returned if the DataDirectory path exceeds certain nested directories link. for eg. the file path specified below.

C:My DocumentsClients CurrentAHW Netcare BenefitsDeliverables1-5 Results Chain - system LevelAlberta NetcareBenefits Logic System Level V01.rcm

Creating a datasource with the file name i.e Benefits Logic System Level V01 every time.
rc = :: SQLConnect(hDbc, (unsigned char *)szSource, SQL_NTS, (unsigned char *)szUserName, SQL_NTS, (unsigned char *)szPassword, SQL_NTS);

Also following error message was encountered during execution of SQLConnect command.

/*szErrorMsg = 0x0012e834 "[Microsoft][ODBC Microsoft Access Driver]General error Not enough information to connect to this DSN with SQLConnect. Use SQLDriverConnect."*/

Thus followed the instruction smentioned in the error message an dtried using SQL DriverConnect() in the following manner.
rc = :: SQLDriverConnect(hDbc, NULL,(SQLCHAR *)"DSN=RCM",SQL_NTS,outstr, sizeof(outstr),
&outstrlen,SQL_DRIVER_NOPROMPT);

Still an error is encountered but this time it returns a RETCODE of 100 whrease earlier it had returned -1.

Inform the procedure to be followed using SQLConnect when DataDirectory path is too long.

An early reply will be appreciated.

Cheers & Regards,
