[QUOTE=timb89;874948]any ideas anyone?[/QUOTE] [URL="http://www.dreamincode.net/forums/showtopic10157.htm"]Here[/URL] is a good tutorial on linked lists amongst other C++ data structures.

[QUOTE=karjan;874395]how i can convert string to int in c++ gui mode[/QUOTE] Please, refrain from hijacking threads.

Maybe you should try a simpler algorithm, like this one: [CODE=cplusplus] int i = 0, j = 0; // Counters string Buffer; // Acts as a buffer containing characters while(getline(FileIn, Buffer, ' ')) { cout << "M[" << i << "][" << j << "] = " << Buffer << …

What are you trying to accomplish with the above code? You seem to have misunderstood the uses of arrays, and its definitely not needed in this implementation... Apart from that, your code just doesn't make sense... I would strongly recommend you take this tutorial of the C++ language, its uses …

> C++ won't allow this. Why? Well, if you have touched upon the subject of templates in C++, then you must know that C++ templates are **type-specific**. This means that once you have declared a pointer(well frankly, *any* instantiation) to a templated class, using a certain `<class>` or `<typename>`, you …

This does have to do with a slope, but of a different sort. When you mean - moving an object in a 2D vector, what do you mean? Do you mean the STL's [ICODE]std::vector[/ICODE]? or mathematical vectors?

Could you at least post your current code for doing whatever it is that you are trying to accomplish?

Yes, I tend to agree with Narue. I would take a pot-shot and ask for you to check the closing statement of your [ICODE]Graph[/ICODE] class, and make sure that it terminates with a [ICODE]};[/ICODE]

Okay, I haven't fully understood your first question, but I'll try and clear up parts of it that I have understood. Just tell us what you want to do in context of the following, or, if this isn't it, could you explain what it is that you want to do …

Which compiler/IDE are you using? [ICODE]<conio.h>[/ICODE] is a non-standard header file. Besides this discrepancy, there seems to be no need for it in your code... If you had compiled this on a new compiler, then this would surely have thrown an error, wouldn't it?

Which IDE are you using? Some IDE's like Dev C++ have the choice of adding your own Application Icon even to Console Projects. Code::blocks has this facility, but you will have to create a separate resource file defining the Icon as a part of your project. But then again, this …

Hi! Firstly, if you're a beginner, then its better if you model your game as a text-based game. Game Programming using graphics, audio etc can quickly become overly complicated if you have little or no previous experience in C++ (trust me on this). You would have to worry about a …

Maybe you should try this: Make the following Window Handles Global: HWND hWndPrincipal; HWND hWndPrincipal2; HWND hWndPrincipal3; HWND hWndPrincipal4; I'm not sure if this will work, but I made a program that is similar to what you are trying to do, and making my handles global resources sorted out many …

Hi, In answer to question 2, you can run a full scan from AVG (which version?), and simply move it to the vault, which is just as effective as getting rid of it from the system as it disables it. Some of the viruses will not 'heal' as it can't …

I've made a program that generates a Character's details(Game details, like level, name, HP, etc, based on a few parameters). I've added another .cpp file to it [without a main() function], but when I try to compile the whole project in Dev-Cpp, it just shows an error. My code is: …
