根据进程名判断进程是否运行

问题描述：

给定进程名，判断该进程是否正在运行。

参考代码：

#include <TlHelp32.h>
BOOL IsProcessRunning(LPCTSTR lpProcessName)
{
    if (NULL == lpProcessName)
        return FALSE;
    HANDLE hProcess = NULL;    
    HANDLE hProcessSnap = NULL;
    PROCESSENTRY32 Info = {
   0};
    hProcessSnap = ::CreateToolhelp32Snapshot(TH32CS_SNAPALL,0);
    Info.dwSize = sizeof(PROCESSENTRY32);
    if(::Process32First(hProcessSnap,&Info))
    {
        do
        {
            CString ss = Info.szExeFile;
            DWORD dwVersion = GetVersion();
            DWORD dwHigh = dwVersion & 0x80000000;
            DWORD dwLow  = dwVersion & 0x000000FF;
            if((dwHigh == 0x80000000) && (dwLow == 4))
            {
                int iFind ;
                if (( (iFind = ss.Find(lpProcessName)) != -1 )&&( (iFind = ss.Find(lpProcessName)) > 0 ))
                {
                    if ((iFind + _tcslen(lpProcessName) == ss.GetLength())&&(ss[iFind-1] == _T('\\')))
                    {
                        CloseHandle(hProcessSnap);
                        hProcessSnap = INVALID_HANDLE_VALUE;
                        return TRUE;
                    }
                }
            }
            else
            {
                if(!ss.CompareNoCase(lpProcessName))
                {
                    CloseHandle(hProcessSnap);
                    hProcessSnap = INVALID_HANDLE_VALUE;
                    return TRUE;
                }
            }
        }while(::Process32Next(hProcessSnap,&Info));    
    }
    if ( hProcessSnap != INVALID_HANDLE_VALUE )
    {
        ::CloseHandle(hProcessSnap);
        hProcessSnap = INVALID_HANDLE_VALUE;
    }
    return FALSE;
}
