| | I recently stumbled upon a boost installer (which I think is awesome), here [url]http://www.boostpro.com/download/[/url] and I was wondering if there is anything similar for QT and Visual Studio 2010?

| | Hi this project is actually C++/CLI but I expected more useful help from the .NET developers (most things are similar). So, I have a transparent form (completely transparent) and I want to draw a visible rectangle onto it and since I am using C++/CLI I was hoping to do it … |
| | The idea(s) aside, how does a lone programmer with a few languages at his disposal make awesome software? Do you think with proper research, planning, and design a lone programmer can make awesome software, or do you think it will usually require a couple of partners? How do I learn … |
| | I'm hoping for a second opinion on which of these two motherboards to buy (I hope this is the right place).

| | Not sure where to post this, hopefully here. Basically if I make an application that does some stuff in the background, how does an antivirus know it isn't a trojan horse or something? Will my application be flagged as a virus, or is it generally safe to assume it won't … |
| | Anyone know of a generic guide for using third party C++ libraries, specifically with Visual Studio 2010? I'm thinking "winging it" isn't cutting it, I want a resource to learn more about how these things are usually prepared, and used. I swear I saw a mention of a library system …  |
| | The worst thing about C++ in my opinion is trying to use a library (with VS2010 at least). It always causes me great pain, and usually I am not met with success. So, I'm trying to use the Magick++ library, which is a part of the ImageMagick program, and I … |
| | Ok so my parents bought a Nintendo Wii to use for Netflix, which is overall pretty sweet for me during the two more months I'll be living at home. So far I'm loving Netflix, but is there any way to pre-load movies instead of streaming them? I would like to …  |
| | So.. I want information on drawing on top of a DirectX game, like how Steam does it. I would consider naively trying to obtain a "device context" of the client area of the game's window, and then try some 2D drawing functions. D: I don't know if that's going to … |

| | Well guys, I'm having a hard time learning enough about ANNs to apply them to a problem. Firstly my general understanding is that the network adapts during the "training" phase to produce the correct output with the given set of inputs. This is obviously useful with image recognition, or handwriting … |
| | I'm sure many of you know how visual studio supports "outlining", it's where a block of code becomes collapsible and it can be expanded or collapsed by the plus sign on the left. Often times those seeking help feel it necessary to dump about 3-4 files into a thread and … |

| | Sooo... Every DLL injection result I've read so far only uses a pre-made DLL, loads it into another process and says "darn I'm good." They do absolutely NOTHING useful and a couple of them are rip-offs of one another only using a different programming language. Google has failed me! Once … |

| | I'm trying to draw a "selection box" with a Graphics created with an HDC to the PrimaryScreen, but it doesn't appear to update properly, as in when I draw something it tends to stay there. Am I doing something wrong, or is there something I'm not aware of? [disregard] Actually … |

| | I have a C++/CLI form, and a native class in separate files. I include the header file of the native class at the top of the Form.h This causes the compiler to try to compile the constructor of the Form as a native function and spits out 100+ errors and …  |
| | Hello, I'm hoping you can help me make a smart decision. I have some code written in native C++, a full program actually--and I need to use it with C#. The application is, at the moment, very basic. It has a console user interface, and settings need to be changed … |

| | What would be a common strategy for using DLLs coded in native C++ in C#? I'm not really finding much good information about it, other than writing the DLL in C.  |
| | I'm just wondering how programmers rate their own skills, for instance I haven't been using C# very long, but I do feel I have a good grasp on the language. If I see on a job listing: "* 3+ years C# or Visual Basic.NET " What the heck is 3+ …  |
| | I have a DataGridView on a form that updates the datagridview automatically and will allow the user to manually edit the information. I need to save the information in the DataGridView somehow. I don't know what the best option would be. I could of course use a file to store … |

| | [url]http://www.boost.org/doc/libs/1_46_0/libs/smart_ptr/shared_ptr.htm#ThreadSafety[/url] This section somewhat confused me, in my code I have a matrix of shared_ptr's pointing to an entirely thread-safe class. But the shared_ptr documentation says it is only as thread-safe as the built-in C++ types. Does this mean that if I read/write to my thread-safe class using shared_ptr's at … |
