CWinThread的使用

      MFC的多线程启动使用的是：AfxBeginThread（），是对CWinThread的一层外包装。直接使用CWinThread会获得更好的控制，还可以储存“线程间通讯”数据。下面是一个简单的CWinThread的子类，其中使用了MFC中未公开的两个东东。程序里面有注释啦。

#include <afxwin.h>

CWinApp TheApp;

class CUserThread : public CWinThread
{
public:  // Member functions
    CUserThread(AFX_THREADPROC pfnThreadProc);

    static UINT ThreadFunc(LPVOID param);

public:  // Member data
    int m_nStartCounter;

private: // The "real" startup function
    virtual void Go();
};

CUserThread::CUserThread(AFX_THREADPROC pfnThreadProc)
 : CWinThread(pfnThreadProc, NULL)  // Undocumented constructor
{
    m_bAutoDelete = FALSE;

    // Set the pointer to the class to be the startup value.
    // m_pThreadParams is undocumented,
    // but there is no work-around.
    m_pThreadParams = this;
}
