c++ 类中静态成员变量vector 初始化 创建线程传递this 指针的使用类成员

最近用mfc做了一个小东西，学到的一些东西。

使用静态成员变量：类中所有成员共享数据 

mfc  线程函数传this 参数   AfxBeginThread(ExportXml, this);

door.h

struct doorInfo
{
	string name;		//用户名
	string userid;		//用户id
	string passwd;		//密码
	int	index;
};

class door
{
public:
	door();
	~door();
	void setvalue(int &i);
	void print();

	void* m_sdkstatus ;
	CWinThread		 *	m_pThread;
public:
	static vector<doorInfo>m_data;

	static UINT ExportXml(LPVOID pParam);
private:
	static doorInfo vecorInit();
