C++ 新建进程和结束进程

//----------------------------------------------------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ID

	int 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 here
	CFileDialog fileDlg(TRUE);
	fileDlg.m_ofn.lpstrTitle=_T("打开文件");
	fileDlg.m_ofn.lpstrFilter=_T("Program(*.exe)*.exeAll Files(*.*)*.*");<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ID
	
	if(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);
}
