I have a DataGridView in virtual mode. I only implemented the CellValueNeeded eventhandler as described in http://msdn.microsoft.com/en-us/library/15a31akc.aspx. Implementing the rest of the events only seems needed when you want to be able to edit the cells manually. I would like to programatically edit a DataGridView cell value. I ...
Scenario: a program running in a byte code virtual machine like Java or Python, wants to evaluate (by compiling on the fly to byte code and then running) a function whose code was automatically generated or supplied from outside. The tricky bit is that the function's code is not trusted -- it may have been generated by a stochastic meth...

How do I get around this? I clearly cannot make the value() method virtual as I won't know what type it is beforehand, and may not know this when accessing the method from b: class Base { public: Base() { } virtual ~Base() { } private: int m_anotherVariable; }; template <typename T> class Derived : public Base { public: ...
Is something similar to this possible? This way it produces an error. class A { public: virtual std::string key; }; class B : public A { public: std::string key; }; int main() { A a; a.key = "Foo"; return 1; } ...

The Problem: I have a class named "shape3d" from which i derived the classes "cube" and "sphere". Now i have to implement "shape3d_stack", which is meant be able of holding objects of the types "cube" and "sphe...
I'm creating a simple p2p application. To test this I'd like to be able to simulate a simple network of about 2-3 computers, such that each instance of the application thinks its on a different computer and talking with others over the network. I considered qemu, but haven't managed to get networking working using VDE or TUN/TAP. is thei...

I have a problem in MSVC++ 2008 where VS2008 is throwing this compile error: error C2509: 'render' : member function not declared in 'PlayerSpriteKasua' Now, what's confusing me is that render() is defined, but in an inherited class. The class definition works like this: SpriteBase -Inherited By-> PlayerSpriteBase -Inherited By-> Pl...
Linux noob question: If I have 500MB of RAM, and 500MB of swap space, can the OS and processes then use 1GB of memory? In other words, is the total amount of memory available to programs and the OS the total of the physical memory size and swap size? I'm trying to figure out which SNMP counters to query, but need to understand how L...
