1、VC++通过进程名或进程ID获取进程句柄HANDLEGetProcessHandle(intnID)//通过进程ID获取进程句柄{returnOpenProcess(PROCESS_ALL_ACCESS,FALSE,nID);}HANDLEGetProcessHandle(LPCTSTRpName)//通过进程名获取进程句柄{HANDLEhSnapshot=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);if(INVALID_HANDLE_VALUE==hSnapshot){returnNULL;}PR

2、OCESSENTRY32pe={sizeof(pe)};BOOLfOk;for(fOk=Process32First(hSnapshot,&pe);fOk;fOk=Process32Next(hSnapshot,&pe)){if(!_tcscmp(pe.szExeFile,pName)){CloseHandle(hSnapshot);returnGetProcessHandle(pe.th32ProcessID);}}returnNULL;}VC由进程ID获取窗口句柄HWNDGetWindowHandleByPID(DWORDdwProcessID
