I noticed that when I make my application with gcc and look at the output during the linking phase, I see the following lib included twice: /home/rb01/opt/trx-HEAD/gcc/4.2.4/lib/../lib64/libstdc++.so And so I was just wondering if this is a problem with g++ (gcc) or if the second one is simply ignored? Thanks! ...
Hi. I develop an application, which automates some simple tasks inside Virtual PC. Now I faced with problem: I can't figure out how I can manipulate mouse inside VPC.

Hi all , I'm beginner to c++ and writing a program that accepts user choices and acts according to it...my only problem is when the user enters Uppercase choice...the program treats it as it's a wrong choice...like if 'e' was a choice for entering a number..if the user entered 'E' the program won't display the "enter the number" message....
If you go to the accepted answer of this post Could someone please elaborate on why he uses: double temp = ::atof(num.c_str()); and not simply double temp = atof(num.c_str()); Also, is it considered a good practice to use that syntax when you use "pure" global functions? ...

First off, I'm programming a game. Currently in the render function there are two calls to two different functions. One renders some text, one renders sprites. On my computer (AMD Phenom(tm) II X4 955 Processor (4 CPUs), ~3.2GHz, 4096MB RAM DDR2, NVIDIA GeForce GTX 285) I have a render speed of ~2200 FPS when rendering around 200 sprite...
Hi all, this may sound too simple, but I'm missing something. I need to write a RAPI Windows Console app using C++. I'm currently using VS2005. I've created a brand new empty Windows Consol app "MyTestRAPI" from documentation, I know I need the include of the "RAPI.H" file. So, I've tried as #include <rapi.h> and also by #includ...
Background: 19th-century German archeologist Heinrich Schliemann was of course famous for his successful quest to find and excavate the city of Troy (an actual archeological site for the Troy of Homer's Iliad). However, he is just as famous for being an astonishing learner of languages - within the space of two years, he taught himself...

In my Win32 app, I don't get WM_MOUSELEAVE messages when I hold down the left mouse button and quickly move the mouse pointer out of the window. But If I, holding down the left mouse button, start from the inside of the window and move slowly past the window edge, it'll generate a WM_MOUSELEAVE. If I don't hold the left mouse button, I...
I have an xml file that is about 42k in size. Shouldn't tinyxml be able to parse a file of this size. Looking at the tinyxml source code, it appears to just read the entire file in as a char *. When I reduce the xml file in size to 7k, tinyxml works just fine. Is there a definitive limit to the # of bytes that tinyxml will parse? ...
I'd like to find a JPEG-writing library that can be statically linked (so there are no DLL dependencies). No JPEG-reading ability is required. Edit: I got LibGD working, but it had one problem described here: http://stackoverflow.com/questions/2307965/libgd-library-is-not-working-crash-when-saving-image ...

Thanks in advance...
Lets say, we have string "ABCAD", now we need to iterate through all possible arrangement of this string in both clockwise and counter-clockwise direction. My ugly implementation looks like this: string s = "ABCAD"; string t =""; for(int i = 0; i < sz(s); i++){ t = s[i]; for(int j = i+1; ; j++){ if((j) == sz(s)){ ...
Can anyone recommend a lightweight open source C++ table data structure that has data access similar to a database table? (i.e. a 2D array but with named columns - ideally, each column will hold data of a single type [see below]). I have had a quick look on Google, but have not found anything very useful. The way I see it, these are th...
