 | Hi Answerers, **Background:** I just figured out how to solve my unresolved external symbols by just dragging the project files from explorer (contained in exe's directory) and plonking them in the dll project, under thier own filter! **Original Situation:** I was getting 'unresolved external symbols' errors because I was #include-ing … |
| | Hi 'Wise & Wonderful Daniwebbers', Why do I keep loosing my project settings when I add a new project to an existing solution? I have to go to every project, in the solution and re-configure each project's: * Include Directories; * Library Directories; * Linker Settings; etc., Which of the … |
| | Hi, The problem I am having is that the returned object, from a dll factory, is not lasting for more than the function scope that recieves it. Despite reading [How to prevent the static initialisation order fiasco](http://www.parashift.com/c++-faq/static-init-order-on-first-use.html) I fail to see how it even applies to my code. `g_spEngineLog` is …  |
| | Hi, When I initialise then access the `g_spMyLog` shared pointer, from within the `CSingleton::CreateLog` member function, it works ok. Accessing the SP from the static member function of `CSingleton::Create()` causes an `access violation` in the original project and an abort in this sample project displayed below. In the original project … |
 | you could have googled and produced... `1km = 1000m, 1m = 100cm, 1km = 100,000cm`. So then... int iCentimeters = /*Whatever space shuttle records in cm*/; int iMeters = int(iCentimeters / 100); int iKilometers = int(iMeters / 1000); The int() will cast away the floating point result. Now just output … |
| | Its true you have to make an effort on your own behalf. But here is the sugar you are after. Read http://www.boost.org/doc/libs/1_55_0/libs/serialization/doc/index.html (All of it!) and here is how to write and read - you can choose whether you want binary or text. Let me know if you need more … |
| | Hi Kind-DaniWebbers, How do you initialise a boost::archive:binary_oarchive in a different place to where you declare it? So: class CBase { std::ofstream m_ofs; boost::archive:binary_oarchive m_binOA(); // <== default constructor virtual void Open(std::string& s) = delete; }; class CDerived : CBase { void Open(std::string& s) override { CBase::m_ofs("filename.bin", std::ios::binary); CBase::m_binOA(CBase::m_ofs, /*flags*/); … |
| | Dear Kind DaniWebbers, I am trying to overload the fstream operators (ofstream/ifstream), so that I can save a class to a 'Binary' file and also display it with cout. But the ways in which each need to be implemented is different. Please can you show me how to define different … |
| | I have read tutorials using my google-fu on how to set up Pre-Compiled Headers, and now I wanted to clear up a few questions: If all the 'to be pre-compiled' headers go in one file - "stdafx.h" then how do you say you only want 1 of those files in …  |
| | Dear Kind-Coders, I am trying to learn to use boost::shared_ptr to manage the lifetime of a DLL, but I am having a type conversion problem whilst setting it up. Please see the following code: #include <boost/make_shared.hpp> int main() { { class CMyClass { public: CMyClass() {} ~CMyClass() {} int MyInt; … |
| | Hi I'm trying to create an array of function pointers contained within a class, the C++11 way. Can I have some help with this as I'm getting a bit mixed up. Here's what I have done so far. They are made up classes to define the problem. #include <iostream> #include … |

| | Hi , Please can anyone help. I have a window(1280x768) that contains a resolution(1920x1080). I am trying to use ScreenToClient to obtain the mouse coordinates while in windowed format. I am drawing a line from a subject to the mouse cursor which works fine in fullscreen but not in windowed. … |
| | Hi, Im using DX9c and learning from Frank Luna's book to try and handle OnLostDevice and OnResetDevice, when switching to fullscreen and back (and alt+tabbing). If I dont draw anything I am able to go from windowed to fullscreen, and back, with no trouble. But adding a draw and flush … |
| | Everything was running fine, then I made a simple change. Like adding a class or two and bang!!! C2995. Can you spot where I have obviously gone blind and cannot see the error. I have header gaurds throughout the solution, so I dont understand why this is happening. Here are … |
| | Re: delete p Sorry if I might be wrong but what I have done is to create a ::destroy() function then I can choose to destroy and handle the deallocation of variables when I choose to do so. Preventing double deletion when the program exits and calls the destructor. |
| | I have written a working templated linked list that can hold a number of Types. Each of which are created with new before sending them to the InsertNode function. in Main: CMyType* pMyType1 = new CMyType; // Create a new MyType* pMyType1->m_iData = 5; // Hold a value LLMyTypes.InsertAtEnd(pMyType1); in … |

| | You are checking the lowesttemp and highesttemp as zero to begin with you need to initialise them as the first element of your chosen array col. So add lowesttemp = temp[LOW][0]; before the for loop and the same with the highesttemp = temp[HIGH][0]; before the for loop again see here: … |
| | Hi, Using Visual Studio 2012. Why does the syntax highlighting turn off periodically. Then unexpectedly it turns back on again, unreproducably, and rather annoyingly. A chocolate eclair for anyone who knows...? |
 | You could RLE Encode that file for speed of loading and save memory (Run Length Encode). |
| | Add a choice "6. To exit" then add a while loop encompassing all the code: While (choice != 6) { // Code here } This gets checked at the begining and end of every loop checking the variable choice is not equal to 6 otherwise it will keep going. Also … |
| | Its not very accomadating you not sharing code back to us, but here's some help anyways... Your value is being increased every frame as it is in the the same code block as your mouse detection code (guessing). Without you taking a risk and showing the code we cant help … |
 | If you coded the game yourself I suggest looking at ways to streamline your data by using bitvalues instead of whole data primitives (as an example). Also reducing the resolution of your graphics files. Otherwise If you bught the game just use Winrar or 7Zip or something to compress the … |

| | Hi I am getting some strange results from my framerate calculation. It seems to have a mind of its own. It wants to stay at about 60 fps even if I set it to 80fps. It does run though if I set it to 50fps. I am getting smooth movement … |
| | **Simple Question:** What is the best way to set the framerate. Is it with GetTickCount() or QueryPerformanceCounter()...? Please can you give me a coded example of how to use whichever one within the 'Game Loop' ? **Advanced Question:** Is it possible to do something in the 'Waiting' part of the … |
