//这个函数返回包含正在运行进程的快照句柄。
//他的原形是：
// HANDLE WINAPI CreateToolhelp32Snapshot(DWORD dwFlags, DWORD th32ProcessID);
// 我们将dwFlags设为TH32CS_SNAPPROCESS，th32ProcessID置为0。
HANDLE hSnapShot=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
//现在我们获得了所有进程的信息。
//将从hSnapShot中抽取数据到一个PROCESSENTRY32结构中
//这个结构代表了一个进程，是ToolHelp32 API的一部分。
//抽取数据靠Process32First()和Process32Next()这两个函数。
//这里我们仅用Process32Next()，他的原形是：
//BOOL WINAPI Process32Next(HANDLE hSnapshot,LPPROCESSENTRY32 lppe);
//我们程序的代码中加入：
PROCESSENTRY32* processInfo=new PROCESSENTRY32;
// 必须设置PROCESSENTRY32的dwSize成员的值 ;
processInfo->dwSize=sizeof(PROCESSENTRY32);
int index=0;
//这里我们将快照句柄和PROCESSENTRY32结构传给Process32Next()。
//执行之后，PROCESSENTRY32 结构将获得进程的信息。我们循环遍历，直到函数返回FALSE。
