Thak you Richard.

If i understand well you say me to use FreeTDS.dll (I think i will use
the same in Windows and in Linux) instead dblib.lib .

  But, where i can find a sample of this in C/C++ (¿what include files
i need?¿where is a sample to use this?), and what is the process to do
it?
  I readed the "FreeTDS User Guide" and i understand that there are
some possible configurations to do it. I don´t know what is the best
for me but, suposssing that i selected one, i don´t know "How to get
what works with it working" (chapter 6 in user guide). There is
nothing about C/C++.


Than you in advance.
