在WinCE 6.0上使用远程桌面控件

说明：这个程序是从命令行执行的，解析命令行传入的参数信息，执行远程桌面连接。只描述实现过程，不讨论实现原理。

1. 打开VS 2005，新建一个“MFC智能设备应用程序”项目

2. 在应用程序类型处选择“单文档”；取消“文档/视图结构支持”；选择“在共享库中使用MFC”
3. 在高级功能处选上“ActiveX控件”和“Windows套接字”
4. 项目新建完成后，从项目源文件中排除"ChildView.h"和“ChildView.cpp”

5. 打开"MainFrm.h"，删除这两个成员变量

 protected:  // 控件条嵌入成员
     //CCommandBar m_wndCommandBar;
     //CChildView    m_wndView;

 

6. 修改以下三个函数函数，注释掉无用的代码

 int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
 {
     if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
         return -1;
 #if 0
     // 创建一个视图以占用框架的工作区
     if (!m_wndView.Create(NULL, NULL, AFX_WS_DEFAULT_VIEW,
         CRect(0, 0, 0, 0), this, AFX_IDW_PANE_FIRST, NULL))
     {
         TRACE0("未能创建视图窗口\n");
         return -1;
     }


     if (!m_wndCommandBar.Create(this) ||
         !m_wndCommandBar.InsertMenuBar(IDR_MAINFRAME) ||
         !m_wndCommandBar.AddAdornments(dwAdornmentFlags))
     {
         TRACE0("未能创建 CommandBar\n");
         return -1;      // 未能创建
     }

     m_wndCommandBar.SetBarStyle(m_wndCommandBar.GetBarStyle() | CBRS_SIZE_FIXED);
 #endif


     return 0;
 }

 

 void CMainFrame::OnSetFocus(CWnd* /*pOldWnd*/)
 {
     // 将焦点前移到视图窗口
 #if 0
     m_wndView.SetFocus();
 #endif
 }

 BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
 {
     // 让视图第一次尝试该命令
 #if 0
     if (m_wndView.OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
         return TRUE;
 #endif

     // 否则，执行默认处理
     return CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
 }

注意：“return CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);”这行代码不能删除，否则无法接收控件事件。

此时项目应该可以编译运行了。我们继续。

7.  代开 “stdafx.h”文件，在“#include <afxdisp.h>” 这行下面添加以下代码

 #include <mstsax.h>

 #include <urlmon.h>

 #include <shlobj.h>

 #include <winnetwk.h>

8. 打开"MainFrm.h"文件，在CMainFrame类中添加以下定义

 public:
     IMsRdpClient  *m_pMsTsc;
     IMsRdpClientNonScriptable3 *pns;
     IMsRdpClientSecuredSettings *pss;
     IMsRdpClientAdvancedSettings *padv;

     CWnd        m_wndMsTsc;

     void RegisterMstscax();
     void UnRegisterMstscax();
     void OnConnecting();
     void OnDisconnected(long discReason);
     void OnEnterFullScreenMode();
     void OnLeaveFullScreenMode();
     void OnLoginComplete();
     void OnConnected();
     void OnRequestGoFullScreen();
     void OnRequestLeaveFullScreen();
     void OnLogonError(long lError);
     void ShowTaskBar(BOOL show);
     int MstscConnect(void);

9. 修改CMainFrame类中的 “// 生成的消息映射函数” 注释下面的代码为

 // 生成的消息映射函数
 protected:
     afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
     afx_msg void OnSetFocus(CWnd *pOldWnd);
     afx_msg void OnSize(UINT nType,int x,int y);

     DECLARE_MESSAGE_MAP()
     DECLARE_EVENTSINK_MAP()

添加了“OnSize”消息处理函数声明和“DECLARE_EVENTSINK_MAP() ”控件消息映射
10. 修改MainFrm.cpp，在消息映射宏里添加“ON_WM_SIZE()”

 BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
     ON_WM_CREATE()
     ON_WM_SETFOCUS()
     ON_WM_SIZE()
 END_MESSAGE_MAP()

11. 在MainFrm.cpp中增加控件事件映射宏

 BEGIN_EVENTSINK_MAP(CMainFrame, CFrameWnd)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 1, CMainFrame::OnConnecting, VTS_NONE)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 4, CMainFrame::OnDisconnected, VTS_I4)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 5, CMainFrame::OnEnterFullScreenMode, VTS_NONE)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 6, CMainFrame::OnLeaveFullScreenMode, VTS_NONE)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 3, CMainFrame::OnLoginComplete, VTS_NONE)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 2, CMainFrame::OnConnected, VTS_NONE)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 8, CMainFrame::OnRequestGoFullScreen, VTS_NONE)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 9, CMainFrame::OnRequestLeaveFullScreen, VTS_NONE)
     ON_EVENT(CMainFrame, AFX_IDW_PANE_FIRST, 22, CMainFrame::OnLogonError, VTS_I4)
 END_EVENTSINK_MAP()

12. 在CMainFrame构造函数中初始化m_pMsTsc为NULL

 CMainFrame::CMainFrame()
 {
     // TODO: 在此添加成员初始化代码
     m_pMsTsc = NULL;
 }

 

13. 在CMainFrame析构函数中释放资源，显示任务栏

 CMainFrame::~CMainFrame()
 {
     ShowTaskBar(TRUE);
     if(NULL != m_pMsTsc)
     {
         m_pMsTsc->Disconnect();
         m_pMsTsc->Release();
     }
     m_pMsTsc = NULL;
 }

14. 实现远程桌面控件事件处理函数

 void CMainFrame::OnConnecting()
 {
 }

 void CMainFrame::OnEnterFullScreenMode()
 {
     ShowTaskBar(FALSE);
 }
 void CMainFrame::OnLeaveFullScreenMode()
 {
     ShowTaskBar(TRUE);
 }

 void CMainFrame::OnRequestGoFullScreen()
 {
 }

 void CMainFrame::OnRequestLeaveFullScreen()
 {
 }

 void CMainFrame::OnLoginComplete()
 {
     LONG style;

     style = GetWindowLong(GetSafeHwnd(),GWL_STYLE);
     style |= WS_MAXIMIZEBOX;
     style |= WS_MINIMIZEBOX;
     SetWindowLong(GetSafeHwnd(),GWL_STYLE,style);

     m_pMsTsc->put_FullScreen(TRUE);
     ShowTaskBar(FALSE);
 }
 void CMainFrame::OnConnected()
 {
 }

 void CMainFrame::OnLogonError(long lError)
 {
 }

 void CMainFrame::OnDisconnected(long discReason)
 {
     ShowTaskBar(TRUE);
     DestroyWindow();
     if(NULL != m_pMsTsc)
     {
         m_pMsTsc->Disconnect();
         m_pMsTsc->Release();
     }
     m_pMsTsc = NULL;
 }

15. 实现OnSize函数

 void CMainFrame::OnSize(UINT nType,int cx,int cy)
 {
     int IsSet=0;
     if(nType==SIZE_MAXIMIZED)
     {
         m_pMsTsc->put_FullScreen(TRUE);
     }
     else
     {
         if(GetSystemMetrics(SM_CXSCREEN)<cx)
         {
             cx = GetSystemMetrics(SM_CXSCREEN);
             IsSet = 1;
         }
         if(GetSystemMetrics(SM_CYSCREEN)<cy)
         {
             cy = GetSystemMetrics(SM_CYSCREEN);
             IsSet = 1;
         }
         if(IsSet)
         {
             SetWindowPos(NULL,0,0,cx,cy,0);
         }

         if(m_pMsTsc != NULL)
         {
             m_wndMsTsc.SetWindowPos(NULL,0,0,cx,cy,0);
         }
     }
 }

16. 实现控件注册、反注册和控件函数

 void CMainFrame::UnRegisterMstscax()
 {       //装载ActiveX控件
     LPCTSTR pszDllName= TEXT("\\windows\\mstscax.dll");

     HINSTANCE hLib = LoadLibrary( pszDllName );
     if (hLib == NULL)
     {
         //AfxMessageBox( _T( "不能载入Dll文件!" ) );
         return;
     }

     //获取反注册函数 DllUnregisterServer 地址
     FARPROC lpDllEntryPoint;
     lpDllEntryPoint = GetProcAddress (hLib,_T( "DllUnregisterServer" ));

     //调用注册函数 DllUnregisterServer
     if( lpDllEntryPoint != NULL )
     {
         if( FAILED((*lpDllEntryPoint)()) )
         {
             //AfxMessageBox( _T( "调用 DllUnregisterServer 失败！" ) );
             FreeLibrary( hLib );
             return;
         }
     }
     //MessageBox(TEXT("调用DllRegisterServer成功!"),TEXT("结果"),MB_OK);
 }
 void CMainFrame::RegisterMstscax()
 {
     //ActiveX控件的路径及文件名
     LPCTSTR pszDllName= TEXT("\\windows\\mstscax.dll");
     //装载ActiveX控件
     HINSTANCE hLib = LoadLibrary(pszDllName);
     if (hLib == NULL)
     {
         MessageBox(TEXT("不能载入Dll文件!"),TEXT("结果"),MB_OK);
         return;
     }
     //获取注册函数DllRegisterServer地址
     FARPROC lpDllEntryPoint;
     lpDllEntryPoint = GetProcAddress (hLib,TEXT( "DllRegisterServer"));
     //调用注册函数DllRegisterServer
     if(lpDllEntryPoint!=NULL)
     {
         if(FAILED((*lpDllEntryPoint)()))
         {
             MessageBox(TEXT("调用Dll Entry失败!"), TEXT("结果"),MB_OK);
             FreeLibrary(hLib);
             return;
         }
         //MessageBox(TEXT("注册成功"),TEXT("结果"),MB_OK);
     }
     else
     {
         MessageBox(TEXT("调用DllRegisterServer失败!"),TEXT("结果"),MB_OK);
     }
 }

 void CMainFrame::ShowTaskBar(BOOL show)
 {
     CWnd *pwndTaskBar;
     pwndTaskBar = FindWindow(TEXT("HHTaskBar"),NULL);
     if(show)
     {
         pwndTaskBar->ShowWindow(SW_NORMAL);
     }
     else
     {
         pwndTaskBar->ShowWindow(SW_HIDE);
     }
     pwndTaskBar->UpdateWindow();
 }

     m_pMsTsc->put_FullScreen(FALSE);
     //padv->put_ContainerHandledFullScreen(TRUE);
     m_pMsTsc->Connect();
     return 0;
 }

17. 在App的InitInstance函数中隐藏主窗口并执行控件连接

 // 唯一的一个窗口已初始化，因此显示它并对其进行更新
 //pFrame->ShowWindow(SW_SHOWMAXIMIZED);
 //pFrame->UpdateWindow();
 pFrame->MstscConnect();
 return TRUE;

到此代码基本准备完成，编译后放到WinCE6.0上应该可以执行远程桌面连接。在某些系统上需要先注册一下Mstscax控件，在命令参数中加入-regmstsc即可，反注册函数没有使用，一般情况下没有这必要。
Good Luck！
