To start program with Qt, You can use 2 free IDEs: CodeBlocks and CodeLite; Both of them work on Linux, and provide the startup creator for Qt4; I have tested CodeBlocks 10.04 and codeLite 2.10 under Debian 6.0.2 and Scientific Linux 6.1; CodeLite 3.0 didn't work due to the lack of wxWidgets 2.9, but with wxWidets 2.8 everything worked well on 32 bit Linux-es. Under 64-bit Debian 6.0.2 worked CodeBlocks, but CodeLite had some bug when tried to read integers with cin under Console application mode. Rgds!

Hi! You can use Qt for graphics programming with C++ in Linux. Regards!

Sooner or later, this this had to happen. It looks that tech advance guides all of us to the final destroy; I only hope that there will be some good guy called Terminator, which will come and resolve this ;P . Salute the new Sarah Connor's birth! :-D To be serious, the history has shown, in several turns, that such occasions were quite unpredictable, and in some phase, the evil has been destroyed; I hope that these robots will stay to serve to their generic role: to help in the manufacture. Otherwise, I'll call my friend Arnold Schwartzeneger (and Chuck Noris, too) to resolve all the dilemmas. ;) Have a good time, all of You, and sleep smoothly! D.S.

Hi! By default, if You write the prototype without any parameters in parenthesis, as in: void die() {}, then C compiler assumes that is such a function You can pass ANY number (of any type) of parameters; If You wish to have a function which will NOT receive any parameter, then, You have to write void die(void){}; (mark the word VOID in the function's parameter list) When C++ or Java is in the concern, then, the empty parenthesis mean that this is the function which does NOT accept the parameters in list; In C++ You can set void in parenthesis, but it is not mandatory. Best regards!

Hi, man! I wish to recommend You the Bruce Eckel's C++ books; you can download them free, and as I know, there was the whole standard C++ language described. The right studio supporting it is VS2005 or 2008; in Visual Studio 6, there is no full support for C++ language, for example, You can't use multiple templates as parameters in templates. So, try with Bruce Eckel's C++. You can find Eckel's site using google or like. Btw, I'm somehow impressed with Your expression that it seems C++ is more wanted by employeers than C#. Although personally I preffer C++ programming, I thought that C# was most wanted. OK, this is a nice news for me! Best regards!

Generally, You have some trouble with optimizations. You have to switch on the release version, and then to REBUILD ALL the code. During the compilation and/or linking process, You have to watch carefully at the bottom of the dev. studio, where the warnings/error messages will be shown. Try to make changes the compiler suggests. If the code doesn't work again, try to switch off as many optimizations as You can. After that, rebuild the code again. You can hope that the code will work OK without any optimization. If the problem disappears, You can try to switch on the optimizations one-by-one, and then rebuild the project any time, searching the bug this way. Anytime, watch on the warnings carefully. By the way, as I know, the stack under debug version has some predefined limit. Try to find the stack settings under the release version, and adjust the value - for example, 1MB or more. D.

Hi! In the book: Using Visual C++ 6, by Jonathan Bates, Timothy Tompkins, You can find the complete explanation what to do, I think even that there is a complete example how to create such an application! The main thing is how to recognize the file attributes, which can be either a Directory or an ordinary file. Then, You have to find which is the "first of" in the current directory (as You iterate through the tree), and which is the "next one". Using the object list, You can pack these file in the structure, and finally, add the images in the directory tree, which is also explained how to create. Best regards, D.

Generally, Your problem is the same as if You had a chess competition. So, You can use some of algorithms which will generate pairs of variations of 2nd class, for n predefined members. Remark: the number of members must be even (that is, any of members has its own 'pair'). If You're interesting in the solution of the chess competition, I can send it to You; although it comes in the MS-DOS-environment C, I suppose it will be good enough for You.
