How can I get the same IP Address I get when I go to "http://www.whatsmyip.org/" using C++ and winsock library? I know how to get the "127.0.0.1" and the router IP "192.168.1.103"... But when I got to "http://www.whatsmyip.org/" I get "65.55.105.132"... How can I accomplish this? ...
Alright, I'm injecting some code into another process using the CreateRemoteThread/LoadLibrary "trick". I end up with a thread id, and a process with a DLL of my choice spinning up. At least in theory, the DLL does nothing at the moment so verifying this is a little tricky. For the time being I'm willing to accept it on faith alone. ...

I have a small question about structures with the LayoutKind.Explicit attribute set. I declared the struct as you can see, with a fieldTotal with 64 bits, being fieldFirst the first 32 bytes and fieldSecond the last 32 bytes. After setting both fieldfirst and fieldSecond to Int32.MaxValue, I'd expect fieldTotal to be Int64.MaxValue, whic...
I find myself constantly running into a situation where I have a set of messages that I need to send over a TCP/IP connection. I have never found a good solution for the design of the message class. I would like to have a message base class where all messages derive from it. Since each message will have different fields, this would allow...

By loading the XTextDocument and doing getText() will give the XText element. More specifically, using an XEnumerationAccess from the XText will only iterate over the TextRange...
I'm working on some code that is normalizing a lot of data. At the end of processing, a number of key="value" pairs is written out to a file. The "value" part could be anything, so at the point of output the values must have any embedded quotes escaped as \". Right now, I'm using the following: outstream << boost::regex_replace(src, ...

So I have starting to learn Qt 4.5 and found the Signal/Slot mechanism to be of help. However, now I find myself to be considering two types of architecture. This is the one I would use class IDataBlock { public: virtual void updateBlock(std::string& someData) = 0; } class Updater { private: void updateData(IDataBlock &...
