I know this must be a pretty common problem, but I haven't been able to find a definitive answer on how to do it. First, assume we have a java server that accepts queries such as (I've just put the relevant lines, and I've taken out the exception handling for clarity): ServerSocket socket = new ServerSocket(port); while (true) ...

I'm starting to learn C, and installed the eclipse plugin for C/C++ development (the CDT plugin). I'm testing the setup with a hello world program, but it looks like the eclipse C plugin (CDT) doesn't have a compiler built in. I thought eclipse plugins were usually self-sufficient? Do I need to install a compiler separately to complete m...
I have a managed object in a c# dll that maintains an anonymous integer handle to an unmanaged object in a c++ dll. Inside the c++ dll, the anonymous integer is used in an std::map to retrieve an unmanaged c++ object. Through this mechanism, I can maintain a loose association between a managed and unmanaged object using an anonymous inte...
Hello, I noticed a very curious behavior that, if standard, I would be very happy to exploit (what I'd like to do with it is fairly complex to explain and irrelevant to the question). The behavior is: static void name(); void name() { /* This function is now static, even if in the declaration * there is no static keyword. Test...
I'm getting started with C and usually use eclipse for other development. But it turned out that the eclipse CDT plugin doesn't come with the compiler and therefore installing a compiler separately is required (since I'm on windows vista). What C/C++ IDEs do you use that you know already come with the compiler. I've been told Microsoft ...

hi together, I was just wondering, whether an array member of a class could be created immediately upon class construction: class C { public: C(int a) : i(a) {} private: int i; }; class D { public: D() : a(5, 8) {} D(int m, int n) : a(m,n) {} private: C a[2]; }; As far as...

I still remember in Delphi, developer can just make the UI(textbox, listbox...) directly connect to database, and then when user click a button, just call the post action, then the data will be saved automatically. What I want to know is that is there any similar mechanism in MFC? Or I can use GetDlgItem(...).Text and then use this v...
