Hi

I am trying to access MySQL DB with C++ Builder 6 pro,
I have Apache 2 under W2000 pro and MySQL 4

I found
http://crlab.com/mydac/
but it is not free
but the trial version seems to work

I will also have a look to :
http://zeoslib.sourceforge.net/modul...name=Downloads

I need things simpler with no VCL
SO I found an example of :

/* mytest.c : do some testing of the libmySQL.DLL.... */
/* */
/* History: */
/* 02/18/1998 jw3 also sprach zarathustra.... */
____________________________________________

it works under C++builder 6 pro in consoile mode and "C" syntax

after rebuilding the .lib .def with implib impdef in order to link them with
his C source

but If I rename its file to .CPP
and rebuild it gives lot of errors (that where warnings before) because of
the use of :
char * pszT;
and mysql DLL functions are returning a const char *

also when I include <VCL.h> file (in order to use VCL forms) then no
building is possible

mysql_com.h
gives errors near :

ypedef struct st_net {
Vio* vio;
unsigned char *buff,*buff_end,*write_pos,*read_pos;
----->>>> my_socket fd; /* For Perl DBI/dbd */
unsigned long max_packet,max_packet_size;


My QUESTION :
Has anybody succeded to compile C++ VCL forms with the standard libmySQL.DLL
given with MySQL

I just need to connect to MySQL DB and do some queries, but I need the full
VCL environement...

give me website or tutorial example / help

Thanks in advance.

Ciao

You are asking your question in the wrong place. Neither comp.lang.c
nor comp.lang.c++ discuss third party libraries like MySQL nor
specific implementations like C++ Builder.

That's good, it is very hard to imaging anything more off-topic in
these newsgroups than Borland's VCL, which is not C or C++ at all but
written in their own proprietary extended version of Pascal.

Presumably, given the name, this program was written in C.

....and according to you, it works as when compiled as C.

Apparently you do not understand that C is not a subset of C++. There
are programs that are perfectly valid C that are not valid C++ at all.
There are several things you can do about this. You could make sure
you understand the differences between C and C++, and manually convert
the source to C++. Or you could look for another source, in C++. You
could write your own C++ code. Or you could buy C++ source code.

Anything at all involving Borland's VCL is completely off-topic here.
As I said, it is not even C or C++. This is discussed in Borland's
support groups, some of which even have .vcl in their names. Try the
news:borland.public.* family of groups on the server
newsgroups.borland.com.

None of your issues have anything to do with the C or C++ languages,
but with non-standard extensions and third party libraries. Your best
bet is the Borland support groups.
