维护进程定期（10s）检查工作进程是否存在。不存在，则创建工作进程。同时杀死多余的工作进程。
1、使用VS2008创建一个带预编译头的控制台项目。
2、源文件内容：
#include "stdafx.h" #include#include #include using namespace std; #pragma once #pragma message("Psapi.h --> Linking with Psapi.lib") #pragma comment(lib,"Psapi.lib") // To ensure correct resolution of symbols, add Psapi.lib to TARGETLIBS // and compile with -DPSAPI_VERSION=1 bool cmpName_processID(TCHAR * pStrProcessName,DWORD processID){ TCHAR szProcessName[MAX_PATH] = TEXT(""); // Get a handle to the process. HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, processID ); // Get the process name. if (NULL != hProcess ) { HMODULE hMod; DWORD cbNeeded; if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod), &cbNeeded) ) { GetModuleBaseName( hProcess, hMod, szProcessName, sizeof(szProcessName)/sizeof(TCHAR) ); } } CloseHandle( hProcess ); if(0 == _tcscmp(pStrProcessName,szProcessName)) { return true; } return false;}void create_process(TCHAR * pStrProcessName){ STARTUPINFO si; PROCESS_INFORMATION pi; ZeroMemory( &si, sizeof(si) ); si.cb = sizeof(si); ZeroMemory( &pi, sizeof(pi) ); if( !CreateProcess(pStrProcessName, //module name NULL, // Command line NULL, // Process handle not inheritable NULL, // Thread handle not inheritable FALSE, // Set handle inheritance to FALSE 0, // No creation flags NULL, // Use parent's environment block NULL, // Use parent's starting directory &si, // Pointer to STARTUPINFO structure &pi ) // Pointer to PROCESS_INFORMATION structure ) { printf( "CreateProcess failed (%d).\n", GetLastError() ); return; } // Close process and thread handles. CloseHandle( pi.hProcess ); CloseHandle( pi.hThread ); return;}void check_create_process(TCHAR * pStrProcessName){ bool bExist = false; DWORD aProcesses[1024], nByteNeed, nProcesses; unsigned int i; if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &nByteNeed ) ) { printf("获取所有进程失败\n"); return ; } // Calculate how many process identifiers were returned. nProcesses = nByteNeed / sizeof(DWORD); for ( i = 0; i < nProcesses; i++ ) { if( aProcesses[i] != 0 ) { if(cmpName_processID( pStrProcessName,aProcesses[i] )) { if(bExist) { HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | // Required by Alpha PROCESS_TERMINATE, FALSE, aProcesses[i] ); if (NULL != hProcess ) { TerminateProcess(hProcess, 0); printf("杀死进程\n"); } } else { bExist = true; } } } } if(bExist)return; create_process(pStrProcessName);}int main( void ) { char ch; //cin>>ch; while(1) { Sleep(10*1000); check_create_process(_T("tt.exe")); } cin>>ch; return 0; }
