//----------------------------------------------------新建进程任务

//点击 "新建任务"按钮 代码如下：

//打开新建任务对话框void CProp_Process::OnClickedBtnNewProcess(){CNewProcess *newProcess = new CNewProcess();  //CNewProcess 为一个CDlgEx类型的对话框类newProcess->Create(IDD_DIALOG_NEW_PROCESS,this); //IDD_DIALOG_NEW_PROCESS为对话框的资源ID</span>newProcess->ShowWindow(SW_SHOW);}

将打开如下图的对话框

//<strong>确定 按钮  新建任务</strong>void CNewProcess::OnBnClickedNewProcess(){WCHAR pszExeName[MAX_PATH]={0};GetDlgItemText(IDC_COMBO_CREATE_PROCESS,pszExeName,MAX_PATH);//获得组合框中输入的路径 //IDC_COMBO_CREATE_PROCESS 为图中组合键的资源IDint codeIndex=CreateNewProcess(pszExeName);//新建任务 调用下面的函数,传入的参数是新建任务（.exe）的完整路径//判断是否成功新建进程CString strWrongPath;strWrongPath.Format(_T("windows 找不到文件' %s ',请确定文件是否正确后,再试一次！"),pszExeName);if(codeIndex==0){AfxMessageBox(strWrongPath);}}

//<strong>新建任务</strong>int CNewProcess::CreateNewProcess(WCHAR pszExeName[])  {  //结构体    PROCESS_INFORMATION piProcInfoGPS;      STARTUPINFO siStartupInfo;      SECURITY_ATTRIBUTES saProcess, saThread;  //初始化结构体    ZeroMemory( &siStartupInfo, sizeof(siStartupInfo) );      siStartupInfo.cb = sizeof(siStartupInfo);      saProcess.nLength = sizeof(saProcess);      saProcess.lpSecurityDescriptor = NULL;      saProcess.bInheritHandle = true;      saThread.nLength = sizeof(saThread);      saThread.lpSecurityDescriptor = NULL;      saThread.bInheritHandle = true;  //创建进程    int isSuccess = ::CreateProcess( NULL,(LPTSTR)pszExeName, <span style="white-space:pre"></span>&saProcess,&saThread, false,CREATE_DEFAULT_ERROR_MODE,NULL,NULL,&siStartupInfo,&piProcInfoGPS );  return isSuccess;}

//<strong>浏览 打开对话框获得进程路径</strong>void CNewProcess::OnClickedView(){// TODO: Add your control notification handler code hereCFileDialog fileDlg(TRUE);fileDlg.m_ofn.lpstrTitle=_T("打开文件");fileDlg.m_ofn.lpstrFilter=_T("Program(*.exe)\0*.exe\0All Files(*.*)\0*.*\0\0");<span class="comment" style="margin: 0px; padding: 0px; border: none; color: rgb(0, 130, 0); font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px;">//过滤exe后缀文件</span><span style="margin: 0px; padding: 0px; border: none; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px;">  </span>if(IDOK==fileDlg.DoModal()){LPWSTR pszExeName=fileDlg.m_ofn.lpstrFile;//获得进程完整路径//CString pszExeName1=fileDlg.GetFileName();//CString pszExeName =fileDlg.GetFolderPath();SetDlgItemText(IDC_COMBO_CREATE_PROCESS,pszExeName);//把路径设置到编辑框中 <span style="font-family: Arial, Helvetica, sans-serif;">IDC_COMBO_CREATE_PROCESS为组合控件ID</span>int codeIndex=CreateNewProcess(pszExeName);//判断是否成功新建进程CString strWrongPath;strWrongPath.Format(_T("windows 找不到文件' %s ',请确定文件是否正确后,再试一次！"),pszExeName);if(codeIndex==0){AfxMessageBox(strWrongPath);}}}

//----------------------------------------------------------结束进程（因为 Win系统权限的问题，所以有的系统进程不能结束）
代码如下

 void EndOfProcess(DWORD PID){      HANDLE hProcess;BOOL isEnd;//PID为进程IDif(szBuf!=NULL){hProcess=OpenProcess(PROCESS_ALL_ACCESS,FALSE,PID);//获取进程句柄if(hProcess==NULL){DWORD dwError=GetLastError();CString strError;strError.Format(_T("获取句柄失败,Error Code is: %d"),dwError);MessageBox(strError);}isEnd=TerminateProcess(hProcess,0);//判断进程是否成功结束if(isEnd){MessageBox(_T("进程结束"));}else{MessageBox(_T("进程结束失败"));}CloseHandle(hProcess);}
