I am able to successfully build solution. but i keep getting this when i try to start debugging or executing it. any suggestions why this might be the case? update: i fixed the issue. I just recreated the proj with empty files and then just rebuild and it worked. one question: when i start the program (its a console app) how do i stop i...
Can anyone explain what they are and why I would need them? What kind of applications am I building if I need to use intrinsics? ...
When double-buffering data that's due to be shared between threads, I've used a system where one thread reads from one buffer, one thread reads from the other buffer and reads from the first buffer. The trouble is, how am I going to implement the pointer swap? Do I need to use a critical section? There's no Interlocked function available...
I want to define a constant in C++ be visiable in several source files. I can image the following ways to define it in header file: #define GLOBAL_CONST_VAR 0xFF int GLOBAL_CONST_VAR = 0xFF; Some function returing the value (e.g. int get_GLOBAL_CONST_VAR()) enum { GLOBAL_CONST_VAR = 0xFF; } const int GLOBAL_CONST_VAR = 0xFF; extern con...
Currently it is floating on top of my rendered window, i dont think thats good for few reasons: 1) i waste rendering time for rendering stuff that isnt visible. 2) it must be rendered every frame again when i wouldnt be updating the whole statusbar every frame anyways. So how i could create a window where it leaves space for my statusba...
i have a program that runs like so: a.out 23421232 now if i use a.out it will tell me check params and gives an example and closes. I am curious if there is a way to add command line args when executing my code in vs2008? ...
I have an application I'm working on that uses two third party libraries, each with pre-compiled libs and dlls, one of which provides necessary .lib files for both debug and release builds (A[d].lib) and the other which provides only .lib files for release builds (B.lib). Compiling in Release mode (using MSVC9) works fine, however attemp...
My goal is to create a program that will take an AVI file as input and then do whatever is necessary to burn it to a DVD. Currently, I use three separate programs to accomplish this. The first tool requires me to convert it from an AVI file to an MPEG. The second tool takes that MPEG and creates DVD files (a VIDEO_TS folder, with a few ...
I have a top-level Qt widget with the FramelessWindowHint flag and the WA_TranslucentBackground attribute set. It has several children, each of which draws an image on it. They are not in a layout. Instead, I simply move them around when something changes (it is not user-resizable). There are two states to the window - a big state and a...
I'm trying to do a double-loop over a std::list to operate on each pair of elements. However, I'm having some trouble initialising the second iterator. The code I'd like to write is: for(std::list<int>::iterator i = l.begin(); i != l.end(); ++i) { for(std::list<int>::iterator j = i+1; j != l.end(); ++j) { ... } } That ...
I'm no delphi wizard but I found this function on a board and I need it badly for C++, Is there somebody who knows Delphi and C++ well enough to convert it? function GetModuleBase(hProcID: Cardinal; lpModName: PChar):Cardinal; var hSnap: Cardinal; tm: TModuleEntry32; begin result := 0; hSnap := CreateToolHelp32Snapshot(TH32CS_SN...
I have three monitors and I want too create a taskbar on all three of them in C++ ? ...
Hi, It's only for 'debugging' purposes, so I don't want to spend a lot of time with this, nor it is very important. The program exports the data as a png, jpg, svg, etc... -so it's not a big deal, though it could be good to see the image while it is being generated. Also, the program is going to be used in a Linux server; but I'll limit...
I just finished reading Accelerated C++. I completed all of the exercises and I am looking for another book to continue developing my knowledge and skills of C++. What is a good book to read after this one? In particular, is Essential C++ by Stanley Lippman a good follow up or is the overlap with Accelerated C++ too large? In your answe...
Calling system() to run an external .exe and checking error code upon errors: #include <errno.h> #include <stdlib.h> function() { errno_t err; if( system(tailCmd) == -1) //if there is an error get errno { //Error calling tail.exe _get_errno( &err ); } } First two compile errors: ...
I'm new to autom4te, and I'm trying to use autoconf/automake to build and link a C++ program on multiple architectures. Complicating the linking is the fact that the project requires boost (filesystem, system, program_options). I'm using boost.m4 (from http://github.com/tsuna/boost.m4/tree/), and it seems to locate all the libraries and...
How would I go about rotating a Bitmap in Windows GDI,C++? ...
Consider the following: std::vector<int> vec(1); // vector has one element std::fill(vec.begin(), vec.begin(), 42); std::fill(vec.begin()+1, vec.end(), 43); std::fill(vec.end(), vec.end(), 44); Will all of the std::fill usages above result in defined behavior? Am I guaranteed that vec will remain unmodified? I'm inclined to think "yes...
I'm using boost to create a directory to place some temp files in. int main( int argc, char* argv[] ) { std::cout << "Current Dir: " << argv[0] << std::endl; boost::filesystem::create_directories( "TempFolder" ); return 0; } Now if double click the exe, the folder "TempFolder" is created in the same directory as the exe, ...
Hi! I'm new to win32api programming. I would like to know how to create a dialog box within a non-gui program (without any resource created). I've seen some examples with that CreateIndirect function. Is it the best method? Any other way? Thanks! ...
