Harry:

The 32bit libraries that I posted for you are currently in production. This 
is a known good build.
This must be an issue in your environment (and in Windows 7, that usually 
means a security issue).

Some questions:


1.       Are you running with Administrator privileges on your Windows 7 box?

2.        Do you have permissions to create a socket?

3.       Have you built a debug library and been able to step through the 
code to the point of failure in FreeTDS?

4.       Does it fail trying to initialize WinSock? Put a breakpoint in 
net.c, around line 136.

5.       What message to you get when you attempt to telnet on port 1433 to 
your SQL Server from the command line?

Oh, just as a curiosity, why are you specifying a character set? My app runs 
just fine using the default (unspecified) one.
Finally, which version of SQLServer are you trying to hit?


Paul

Yes I am. (dblib to Sql Server 2008).



Now for the bad news: my Visual Studio C++ Console app is not working.

It was quietly dying before, which I only realized after adding some code to 
retrieve data.



There seem to be 2 issues: an unable to open socket error, and the error 
handlers not getting installed ( I think as they're not being called), so the 
program just crashes.

This is after calling dbopen(), and it is in tdserror(...) The actual message 
is "Unable to open socket" (by inspecting the variable msg) but the program 
crashes when trying to call rc = tds_ctx->err_handler(tds_ctx, tds, &msg);



Qt seems to link fine now, but also quietly dies - I guess it's for the same 
reason.

Maybe it's the socket libraries I'm linking?

I used WS2_32.lib , odbc32.lib, odbccp32.lib (and of course the other 3 
libraries).



I tried both Win32 and x64 builds - same results. And of course I do have 
connectivity to my server.



My freetds.log mentions the following:

(the FreeTDS 0.65 strikes me as very odd, as I am working with 0.82)



My program is dead simple:

int main(int argc, char **argv)

{

    LOGINREC *login;

    RETCODE erc;

      DBPROCESS *dbproc;

      dberrhandle(syb_err_handler);

    dbmsghandle(syb_msg_handler);



    if (dbinit() == FAIL) {

            return -1;

    }



    if ((login = dblogin()) == NULL) {

            return =2;

    }



    dbsetifile((char*)"C:\\Users\\harry.MISSIRIAN\\freetds.conf");



    DBSETLUSER(login, "***" );

    DBSETLPWD(login,  "***" );

    DBSETLCHARSET(login, "CP1253" );

    if ((dbproc = dbopen(login, "sql" )) == NULL) {

            return -3;

    }





and my freetds.conf is like this:

[sql]

      host = 10.1.1.11

      port = 1433

      tds version = 8.0

      dump file = C:\Users\harry.MISSIRIAN\freetds.log

      debug flags = 0xffff
