MFC中关于子进程创建和关闭操作

创建子进程　　

PROCESS_INFORMATION ProcessInfo; 
    STARTUPINFO StartupInfo; //This is an [in] parameter
    ZeroMemory(&StartupInfo, sizeof(StartupInfo));
    StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field
    //processHandle = CreateProcess(_T(".\\MyTwain\\Debug\\MyTwain.exe"), NULL,NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo);
    if(CreateProcess(_T(".\\MyTwain\\Debug\\MyTwain.exe"), NULL,NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo))
    { 
     //   hProcess = GetCurrentProcess();
        KillTimer(1);
        SetTimer(1,1000,NULL);
        //WaitForSingleObject(ProcessInfo.hProcess,INFINITE);
        //CloseHandle(ProcessInfo.hThread);
        //CloseHandle(ProcessInfo.hProcess);
        //MessageBox(_T("1"));
        //HANDLE MyProcess = GetCurrentProcess();
        //TerminateProcess(ProcessInfo.hProcess, 0);
    }  
    else
    {
    MessageBox(L"The process could not be started...");
    }

关闭子进程：

在类视图-》CXXXDlg函数点击鼠标右键-》消息-》WM_DESTROY，添加ondestory函数

TerminateProcess(ProcessInfo.hProcess,0);//第一个参数为要关闭的进程的句柄
