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;
    }
    
    int _tmain(int argc, _TCHAR* argv[])
    {
        BOOL bRet = IsProcessRunning(L"kxescore.exe");
        return 0;
    }
