Well I suppose there are different limits for Windows, Linux, BSD. Also it depends on system architecture: i386, amd64, ia64 and so on. Formula on Wikipedia says The maximum value is 2CHAR_BIT*sizeof(size_t) - 1, or the constant SIZE_MAX in the C99 standard. I assume you should check this constant.

Hmmm? Did I mentioned that it is resolved? It's not :( I have only temporary solution using another sequence for id generation.

Well, socket interface works at lower level then QT. QT is wrapper for many functions.

Great piece of code ;)

Thaks, cap XD.

Try to learn programming. If you cannot create simple project then we cannot help you.

Strange only idea is that in DLL code returned variable is declared as static.

Limit won't work in SQLServer 2005

Which part of this site should I concentrate on?

As game developer I laugh

There should be such thing as TCP/IP configuration.

Hmm, actually for me it look like reference to pointer to char array. May be you can try *name?

Can you please post Delphi code too?

Then IF statement is correct because Me.hide() is being performed. Check the problem with form1.show()

You need this ports for listening on them?

I mainly work under Linux using C++. So I don't think that my code will help you :(

It depends on layout and what you would like to achieve.

don't have SQLServer 2005 near. In MySQL following works:
SELECT * FROM `gifts` WHERE CONCAT_WS(' ', `from`, `ts`) = '1 1'

try:
SELECT (name + ' ' + surname) AS emp_id FROM employees WHERE emp_id = 'Mohit Roy'

NO LIMIT? Wow!

SELECT column, ROW_NUMBER() OVER (ORDER BY column DESC) AS num WHERE num = 2 ?

Programmer would hang up receiving undefined task which must be done :)

It is IPv6 address.

I am not C# programmer. I don't know all library functions. But you can google them out simply. Try searching for mutex, thread, filesystem routines.

Try tracing line by line. I am sure you'll see content of all variables ;)

May be Adobe AIR for both client and server?

As Java does. This will lead to another holywar. :D I am for Java :D

Agree.

Are you sure he was talking about interface language?

You can create 5 threads. Which of them checks last change date of each XML file. For example, it can do this once per second. If file has changed, we parse XML and perform insertion. Each of threads can establish its own connection to database or use common connection protected by mutex. (http://en.wikipedia.org/wiki/Mutual_exclusion)

Dunno if this is possible in C# but in Java you can use getStackTrace() on exception object. So you can create one global try/catch :D and use this thing on it ;)

I always used libmysqlclient with C API. This code was result of googling ;) May be you can try to dump driver variable and see what it contains.

Remember, you have to also think by yourself ;)

Well, didn't check all code. But you'll at least get correct randomized array. Your version heads to access violation. You can give it a try.

Noticed incorrectness in posted code. There should be object * instead of object. That's why your gcc throws an error.

Actually it is strange that gcc doesn't compile cause reinterpret_cast changes one data type into another. It should be used to cast between incompatible pointer types.

http://www.cppreference.com/wiki/keywords/reinterpret_cast

I use gcc 4.4.3 and it is ok for me. If i use memcpy, the memory is said to be initialixed. If I init object members `by hand` valgrind gives an error. I have std::map which contains a lot of objects of mixed type: so i use void *. When I need to place an object in this map, I allocate memory and memcpy the data or in case of `object` type initialize values.

Please read my comments carefully. I said that we'll get such a mess if we #include .lib file.

Preprocessor doesn't compile anything. It only inserts and swaps text blocks. So after preprocessing you'll have both textual and binary data in one file that cannot be compiled.

What kind of database are you using? I am capable to write something in PHP or Bash for linux and mysql. You can store some kind of a revision in table, change it when database changes and check it. Instead of script you can use daemon programm.

#include directive simply includes file - inserts in contents instead of it. That is why you get large amount of binary data. Linker uses lib files to extract functions from them. C compilers usually parse files only once and the send them to linker. .lib inclusion possibility will require compiler to parse files twice.

Imagine that there is .i file gained after preprocessing stage. it contains both source code and binary data from .lib file. What compiler should do with this? It is not compiler's task to parse binary libraries. It creates object files. Linker searches in the .lib files for symbols (functions, variables, constants etc) that aren't located in object file.
Also .h files allow not to duplicate code. Imagine we have compiler that dissassembles .lib files. I have 2 files that use math.lib. So code is being duplicated. What to do? Which function to use? I'll have to write something like

#ifndef math_lib_included
    #define math_lib_included
    #include <math.lib>
#endif

Correct, my error. They are written in C. But this doesn't change the things. #include directive simply puts the contents of included file into into file where it is used. I can use #include . As a result I'll get large amount of binary data in my source file. Header files are used by preprocessor and allow one declaration for multiple files. While .lib fails contain native assembly. So .lib file are at least not portable. Header files are.

I always used Regexp and onkeyup for such purposes.

I don't think it is possible to make SQL server notify something on changes. Are you sure you need this? What if your database changes very frequently? You can make some kind of script that checks database in every XXX minutes and sends you notification if changes appeared.

And when this function is fired?

I assume adding onChange() handler would be better. You can use regular expression for checking current value and restore older one if it doesn't pass the restrictions.

Agree, server-side checking should always be enabled.

Thanks for your answer!

About all the things you've mentioned:
1. I have -Wall and -Werror flags set in gcc. It compiles.
2. malloc is only choise here :(

Konstantin

Wait wait wait!

I initialize values:

d -> type = MINIGAMEZ_TYPE_OBJECT;
d -> value = map<string, void *>();

Without this really doesn't work. Segmentation fault appears and so on. With this two lines everything works just great. No errors, no leaks, no faults. Only valgrind report.
