Question

VC判断进程是否存在？比如我想知道记事本是否运行，要用到哪些函数？

Answer 1

const char DESTPROC[19] = "cmd.exe"; DWORD pid = ProcessToPID(DESTPROC); 返回为0就是没有 DWORD ProcessToPID(const char *InputProcessName) { DWORD aProcesses[1024], cbNeeded, cProcesses; unsigned int i; HANDLE hProcess = NULL; HMODULE hMod = NULL; char szProcessName[MAX_PATH] = "UnknownProcess"; AddPrivilege(SE_DEBUG_NAME); // 计算目前有多少进程, aProcesses[]用来存放有效的进程PIDs if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) ) { return 0; } cProcesses = cbNeeded / sizeof(DWORD); // 按有效的PID遍历所有的进程 for ( i = 0; i < cProcesses; i++ ) { // 打开特定PID的进程 hProcess = OpenProcess( PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, aProcesses[i]); // 取得特定PID的进程名 if ( hProcess ) { if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod), &cbNeeded) ) { GetModuleBaseName( hProcess, hMod, szProcessName, sizeof(szProcessName) ); //将取得的进程名与输入的进程名比较，如相同则返回进程PID if(!stricmp(szProcessName, InputProcessName)) { CloseHandle( hProcess ); return aProcesses[i]; } } }//end of if ( hProcess ) }//end of for //没有找到相应的进程名，返回0 CloseHandle( hProcess ); return 0; } --------- 也可以枚举得到所有进程的应用程序名，然后和知道应用程序名比较判断。
