VC++信息安全编程（5）实现进程监视清除多余进程

	 

	 

	创建多进程处理程序的时候，需要对多进程进行监视，例如QQ启动多了，内存很卡，就得清除一些多余进程。

	 

	 

	 

	 

	 

	 

	 

	详细请见代码分析，实现进程监视与清除多余进程

	 

	#include "stdafx.h"

	#include "GetAllInfo.h"

	#include "GetAllInfoDlg.h"

	 

	#ifdef _DEBUG

	#define new DEBUG_NEW

	#undef THIS_FILE

	static char THIS_FILE[] = __FILE__;

	#endif

	CGetAllInfoDlg *mys=(CGetAllInfoDlg*)param;

	   mys->OnGetProcess();

	   do{

	    mys->ScanProcess();

	 

	   }while(mys->status);

	 

	 

	return 1;

	}
