i have said this over and over again, but people appear not to be 
listening and twisting my words:

the main version of mysql++ (1.7.9) works fine under the unix platforms as 
far as i know. SSQLS, all template functions, etc, are all working 
correctly under it!

the mysql++ version which i ported to VC++ (1.7.1) has, on the other hand, 
a number of bugs. these bugs are purely caused by the fact that VC++ can't 
handle the amount of templates in mysql++. this is purely a fault of 
microsoft's compiler which doesn't adhere to ANSI C++ standards, not of 
the programmers of mysql++. these bugs can only be solved by rewriting all 
these templates, which is not a simple task.

here is a list of bugs that are known to me IN THE VISUAL C++ VERSION 
ONLY:

- the SSQLS are working, but only if you use relatively small structs 
(smaller than 16 i believe) and use vectors for storing the data. 
otherwise VC++ bugs out and gives an internal compiler error.
- the auto-quoting system doesn't work when doing queries (also due to 
template problems). this can be worked around by just adding quotes 
manually to your query/data strings.
- VC++ has support for longlongs, but no ANSI functions that support this 
type (like strtoll), so this type isn't really supported under VC++

furthermore, i want to say that i'm not officially connected to MySQL AB. 
i'm just somebody who did a C++ project under VC++ and needed mysql 
support. i found out about mysql++, which was just what i needed. but to 
my disappointment only unix and borland platforms were supported. 
however, instead of whining to the programmers about this, i ported it to 
VC++ myself, originally only for use with my own project. because i only 
needed its basic functionality i didn't really care to test its more complex
functions (the basic functionality is really working quite fine).
later i thought that there might be more people who wanted a VC++ version 
of MySQL++, so i posted my port to the maintainer of mysql++ who put the 
package on the website.
now, since i finished my project, i'm not really doing anything with 
mysql++ anymore, which means that i'm not going to fix the bugs in the 
VC++ version unless somebody employs me for it.

so, basically, if you want a VC++ version of mysql++ without these bugs, 
please feel free to just take the code and fix it. it isn't open-source 
for nothing after all.

however, what i can't stand is that somebody, who encountered these bugs 
in my CONTRIBUTED VC++ version, goes screaming around that mysql++ is a 
completely bad product because of that.
if you want to use the C version, by all means do that. if you want to use 
the VC++ version without bugs, go contribute a new one!
