You can do this a lot easier:

WriteRegStr HKLM "Software\\ODBC\\ODBC.INI\\ODBC Data Sources" "Servername" "SQL Server"
WriteRegStr HKLM "Software\\ODBC\\ODBC.INI\\Servername" "Description" "Your description"
WriteRegStr HKLM "Software\\ODBC\\ODBC.INI\\Servername" "Driver" "$SYSDIR\SQLSRV32.DLL"
WriteRegStr HKLM "Software\\ODBCß\ODBC.INI\\servername" "Server" "your SQL Server" 

yes, i understand but it's possible to use a api function and i want understand what's wrong with the call

Shouldn't those \0 be real nulls? The System plug-in doesn't do that conversion automatically. Try using nsODBC, it should handle this for you.
