通过进程快照的方式查找指定程序 

 1 BOOL FindProcessByName(LPCTSTR szFileName, PROCESSENTRY32& pe)
 2 {
 3     HANDLE hProcess;
 4     PROCESSENTRY32 lpe = 
 5     {
 6         sizeof(PROCESSENTRY32)
 7     };
 8 
 9     CString strFileName(szFileName);
10     strFileName.MakeLower();
11 
12     hProcess = ::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
13     if (hProcess == INVALID_HANDLE_VALUE)
14     {
15         return FALSE;
16     }
17 
18     BOOL isExist = ::Process32First(hProcess, &lpe);
19     BOOL isRuning = FALSE;
20     CString strName;
21     while(isExist)
22     {
23         strName = lpe.szExeFile;
24         strName.MakeLower();
25         if (strName == strFileName)
26         {
27             isRuning = TRUE;
28             break;
29         }
30 
31         isExist = ::Process32Next(hProcess,&lpe);
32     }
33 
34     if (isRuning)
35     {
36         memcpy(&pe, &lpe, sizeof(PROCESSENTRY32));
37     }
38 
39     CloseHandle(hProcess);
40     return isRuning;
41 }


需要头文件 #include <TlHelp32.h>
