Sorry - miss-click.

in result DBPROCESS is NULL.

I try to debug what happens in dbopen, and figure out tat connection
established properly.
Problem in function tds_goodread() for stack:

> vs_plugin_db_mssql.dll!tds_goodread(tds_socket * tds, unsigned char *
buf, int buflen, unsigned char unfinished) Line 437 C
  vs_plugin_db_mssql.dll!goodread(tds_socket * tds, unsigned char * buf,
int buflen) Line 504 C
  vs_plugin_db_mssql.dll!tds_read_packet(tds_socket * tds) Line 530 C
  vs_plugin_db_mssql.dll!tds_get_byte(tds_socket * tds) Line 73 C
  vs_plugin_db_mssql.dll!tds_process_login_tokens(tds_socket * tds) Line 336
C
  vs_plugin_db_mssql.dll!tds_connect(tds_socket * tds, tds_connection *
connection, int * p_oserr) Line 469 C
  vs_plugin_db_mssql.dll!tds_connect_and_login(tds_socket * tds,
tds_connection * connection) Line 510 C
  vs_plugin_db_mssql.dll!tdsdbopen(tds_dblib_loginrec * login, const char *
server, int msdblib) Line 1232 C

Maybe I forgot some params for connection?
