For the following questions, answers may be for C/C++, C#, or Python. i would like the answers to be cross platform if possible but i realize i will probably need conio or ncurses how do i output colored text? how would i do a GUI like top or nethack where certain things are "drawn" to certain spaces in the terminal? if possible a ...
I work in an environment where, for historical reasons, we are using a hodgepodge of custom utility classes, most of which were written before STL arrived on the scene. There are many reasons why I think it is a good idea to at least write new code using STL, but the main one is that I believe it increases programmer productivity. Unfort...
I have written some code that makes use of an open source library to do some of the heavy lifting. This work was done in linux, with unit tests and cmake to help with porting it to windows. There is a requirement to have it run on both platforms. I like Linux and I like cmake and I like that I can get visual studios files automatically ...
I have an application that opens up IE browser windows at certain intervals throughout the day. I would like to control the monitor that the browser window opens up to (for example browser1 opens on monitor1 and browser2 on monitor2 and browser3 on monitor1 and browser4 on monitor2). Is there a way using C++ (app is written in C++) to co...
I have a large project that has > 1000 files. When I press the green 'Play' button to start debugging, once everything is built, it can take up to 5 minutes for the app to start running. It looks like Visual Studio is loading and unloading various DLLs, but it also just sits there occasionally doing nothing. Running from the command li...
I wanted to speed up compilation so i was thinking i could have my files be build on a ramdisk but also have it flushed to the filesystem automatically and use the filesystem if there is not enough ram. I may need something similar for an app i am writing where i would like files to be cached in ram and flushed into the FS. What are my ...
I'm storing images as arrays, templated based on the type of their elements, like Image<unsigned> or Image<float>, etc. Frequently, I need to perform operations on these images; for example, I might need to add two images, or square an image (elementwise), and so on. All of the operations are elementwise. I'd like get as close as possibl...
This is a memory allocation issue that I've never really understood. void unleashMonkeyFish() { MonkeyFish * monkey_fish = new MonkeyFish(); std::string localname = "Wanda"; monkey_fish->setName(localname); monkey_fish->go(); } In the above code, I've created a MonkeyFish object on the heap, assigned it a ...
Good night :) I am currently playing with the DevIL library that allows me to load in image and check RGB values per pixel. Just as a personal learning project, I'm trying to write a very basic OCR system for a couple of images I made myself in Photoshop. I am successfully able to remove all the distortions in the image and I'm left wi...
I've asked a couple questions (here and here) about memory management, and invariably someone suggests that I use boost::shared_ptrs. Given how useful they seem to be, I'm seriously considering switching over my entire application to use boost::shared_ptrs. However, before I jump in with both feet and do this, I wanted to ask -- Has...
What is the correct way to declare and use a FILE * pointer in C/C++? Should it be declared global or local? Can somebody show a good example? ...
Is it wrong to use m_varname as public and the same class with _variable as private ...
I'm looking for detailed informations regarding the size of basic C++ types. I know that it depends on the architecture (16 bits, 32 bits, 64 bits) and the compiler. But are there any standards ? I'm using Visual Studio 2008 on a 32 bit achitecture. Here is what I get : char : 1 byte short : 2 bytes int : 4 bytes long : 4 byt...
Alright. So I wanted to use a file written in c in c++. I ran the code in c and had absolutely no problems. Since I don't know c, I worked with some conversion software for a while, but it wasn't effective (guessing the coding format wasn't in the style it needed). I decided to try it out myself and it looked like all I had to do was ch...
Again me with vectors. I hope I'm not too annoying. I have a struct like this : struct monster { DWORD id; int x; int y; int distance; int HP; }; So I created a vector : std::vector<monster> monsters; But now I don't know how to search through the vector. I want to find an ID of the monster inside the vector. ...
I need to get a list of applications that are currently running so that my C++ application and make them take focus. Has anybody done this? ...
I want to use a library that makes heavy use of singletons, but I actually need some of the manager classes to have multiple instances. The code is open source, but changing the code myself would make updating the lib to a newer version hard. What tricks are there, if any, to force creation of a new instance of a singleton or even the w...
Is there any way to check the status of the RPC connection from the server-side? I am looking for a way to detect if the connection from the client is lost, be it client crash or other connectivity issues. ...
I am using Stackdumps with Win32, to write all return adresses into my logfile. I match these with a mapfile later on (see my article [Post Mortem Debugging][1]). EDIT:: Problem solved - see my own answer below. With Windows x64 i do not find a reliable way to write only the return adresses into the logfile. I tried several ways: Tri...
Hi, i'm looking for a trick to remove an CMFCRibbonPanel from CMFCRibbonCategory. There is just AddPanel() function in the CMFCRibbonCategory, but no RemovePanel(). Do I really need to rebuild my whole CMFCRibbonCategory to do this? EDIT: Just for clarification, what i want is to remove panel itself from the category and not the elem...
