 | I hooked a game's OpenGL.dll with my own glwrapper but this game uses two dll's.. It uses a wrapper of OpenGL32 and my hook is also a wrapper. So what I need: I want to know if these symbols point to the same functions.. http://i.imgur.com/eMZC5.png @28, @28, @28.. That means …  |
| | I've hook a game that uses OpenGL and I'm trying to draw text on the window but when drawn, it has a background that I do not want. Currently i'm using: void glPrint(HDC DC, COLORREF Colour, int X, int Y, const char* format, ...) { if (format == NULL) return; … |
| | So... I'm looking into learning Assembly. I downloaded the FASM assembler and I want to know how useful is assembly? I want the opinion from Cpp programmers because assembly programmers always tell me it's the best language -__- Also quick question: How do I know which register to put stuff …  |
| | How can I get SetConsoleTextAttribute to work with my Console? I tried everything. First I redirected the cout and cin buffers so that my console can have input and output. But now it doesn't have Colour :S I used: HANDLE OutputHandle = GetStdHandle(STD_OUTPUT_HANDLE); SetConsoleTextAttribute(OutputHandle, 10); I don't think GetStdHandle is … |

| | I have a Two Test classes that use variadic templates but I made the constructors explicit so that the compiler doesn't convert anything and leave everything as it was. One class was Array and the other was called 2DArray. When I intialize 2DArray, the compiler was converting its arguments to …  |
| | I'm trying to test my copy con and move con as well as their assignment operators. It NEVER gets invoked :S Copy con gets invoked just fine but the assignment operators are never called and neither is the move constructor. How can I test it to make sure it works … |
| | > "warning: 'class Debug' has pointer data members but does not override 'Debug(const Debug&)' or 'operator=(const Debug&)' [-Weffc++]" The only pointer member I see here is the HANDLE hTHread.

This is my example so far: class MemberRawArrayVector { private: vector<unsigned char> MemberRawArray; public: MemberRawArrayVector(int … |
| | Why does the following code skip the initialization of values of the temporary created? Box::Box() : X1(0), Y1(0), X2(0), Y2(0), W((X2 < 0 ? -X2 : X2) - (X1 < 0 ? -X1 : X1)), H((Y2 < 0 ? -Y2 : Y2) - (Y1 < 0 ? -Y1 : Y1)) … |
| | I'm a bit confused atm, I don't know when to use const T& or T& or T as a parameter. Currently I'm doing: void Resize(std::vector<T> &Vec, const size_t &NewLength) //Ahh edited the function as a result of Lucaci's answer. { Vec.resize(NewLength); } //But thinking of doing: void Resize(std::vector<T> &Vec, size_t … |
| | I have the following code to take a bitmap of a portion of the screen specified by the Box Area. Area is just a struct that holds Width, Height, X1, Y1, X2, Y2 and represents a box. Basically a RECT with additional features. For some reason, if Box is (0, … |
| | I've just read a tutorial on Classes Under the hood/behind the scenes. It says that: Foo* A = new Foo(); // Is different from: Foo* B = new Foo; What in the world? I never put the brackets for my classes like that. Why does the first initialize variables and … |
| | I just learned C++ style casting and the 4 types of casts. I'm not sure if I'm abusing it though. Examples: typedef long (*stringFromString)(int, char*) __cdecl; //TO: typedef long static_cast<*stringFromString>((int, char*)) __cdecl; SmartSetup((char*)World.c_str(), (char*)",f5", 765, 503,(char*)""); //TO: SmartSetup(static_cast<char*>(World.c_str()), static_cast<char*>(",f5"), 765, 503, static_cast<char*>("")); memcpy(&INH, (void*)((DWORD)Buffer + IDH.e_lfanew), sizeof(INH)); TO: memcpy(&INH, static_cast<void*>(static_cast<DWORD>(Buffer) … |
| | I have just came across a class for the first time ever that does not have variables in any of it's declarations but has them in the implementation. Why is this class behaviour allowed? What are the benefits of not putting variable names? class Testing { public: Testing(int, int, int); … |
| | This works fine. For any type I create (Example): BoxArray& operator -= (const Box& B); BoxArray& operator -= (const BoxArray& BA); BUT when it comes to my literal types like char's and strings and char*'s, I get Ambiguous overloads: StringArray& operator -= (const std::string& S); StringArray& operator -= (const StringArray& … |
| | Hey when I don't template my classes, I can pass member functions to eachother normally. But when I template it, I get errors. The two functions are defined as so: CustomType& Delete(int Position); CustomType& Delete(T ValueToDelete, bool All = false); CustomType& Delete(CustomType ValuesToDelete); And Implemented like this: template<typename T> CustomType<T>& … |
| | How can I do the following but easier? I'm templating a class but I want it so that if typename T is of a literal type such as a string or char, then it can use the following member-function. If not then it cannot use it. I've been using typeid …  |
| | I've read that anonymous structs are a compiler extension and codeblocks allows them as long as -pedantic-errors are not enabled. My question is, since it is not legal in C++, what would be the legal equivalent of: typedef union XYZ { int Color; struct { BYTE X, Y, Z; }; … |
| | How can I cast a class to another type? Example: class Point { Point(int X, int Y); }; Point A(10, 10); POINT P = (POINT)A; A = (Point)P; //I've tried: Point::Point(POINT P) : X(P.x), Y(P.y), Color(0) {} //Constructor. Point& Point::operator ()(POINT P) { if (X != P.x && Y != … |
| | Well I like to learn as much code as I can in a day and I just came across the copy constructor. I do not understand when I need to use it. Do I need to use it for every class I make? I came across it after getting the … |
| | Yesterday I took a dive into smart pointers and wasn't sure when I should use them vs. Raw pointers. I found out they are quite useful but they do not work all the time for me. Example of working: char* Buffer = new char[1024]; fread(buffer, 1, sizeof(buffer), infile); //took out … |
| | Why does this say shaddowing? If I change my member X and Y to `_X, _Y` then when I access my class via the dot operator, it shows FOUR values.. Current Class: class Point { public: int X, Y; Point(int X, int Y); ~Point(); }; Point::Point(int X, int Y) : … |
| | I'm trying to figure out why I should convert all my unsigned ints/shorts to size_t. I'm doing the things below but I'm not sure which one to use and which type to iterator my for-loop with: unsigned short Size() { return vector.size(); } int Size() { return vector.size(); } unsigned … |
