Hello everyone. I was just messing with having multiple windows in one instance of the program, so I decided to make a class that keeps a list of the windows:
  
class cWinList
{
private:
	static vector<cWindow> winList; //cWindow is my

                                        // Window class


public:
	static void Add( cWindow window );
};   
Then when I define the add funtion to be this:
  
void cWinList::Add( cWindow window )
{
	winList.push_back( window );
}   
I get a linker error saying error LNK2001: unresolved external symbol "public: static class std::vector > cWinList::winList" (?winList@cWinList@@2V?$vector@VcWindow@@V?$allocator@VcWindow@@@std@@@std@@A) Does anyone know what I am doing wrong? Thanks.

You have to ALSO declare static members outside the class definition, like this:

vector[cWindow] CWinList::winList;

I believe that's correct.

BAH - substitute less than and greater than for the brackets!!

You have only declared the static variable, you also need to define it. You should add this to your implementation file:

vector<cWindow> cWinList::winList;
