>I looking for a sample code to connect VFP Databases thought ODBC using SQLDriverConnect command to create runtime System DSN. Does somebody could help me ??

An example for connecting to Oracle:

lnHandle = sqlstringconnect('Driver=Microsoft ODBC for Oracle;ConnectString=reg6;UID=' + lcUser + ';PWD=' + lcPassword + ';')

I use a VFP form to gather user login info -- lcUser and lcPassword.
