C# 調(diào)用 Google Earth Com API開(kāi)發(fā)(二)

繼《C#調(diào)用GoogleEarth Com API開(kāi)發(fā)(一)》,我Neil又帶給大家第二篇文章,。這一篇文章在第一篇的基礎(chǔ)上,,展示如何調(diào)用Windows API將GoogleEarth的界面隱藏掉,并將GoogleEarth的地圖顯示在自定義的窗體上,。廢話少說(shuō),,直接上代碼。

1,、主窗口代碼:

   1: // 功能:GE實(shí)例(二)
   2: // 描述:GE COM API 網(wǎng)址:http://earth.google.com/comapi/index.html

  22:         static readonly Int32 WM_QUIT = 0x0012; 
  23:  
  24:         private IntPtr GEHWnd = (IntPtr)5;
  25:         private IntPtr GEHrender = (IntPtr)5;
  26:         private IntPtr GEParentHrender = (IntPtr)5;
  27:         /// <summary>

  33:         {
  34:             InitializeComponent();
  35:         }
  36:  
  37:         protected override void OnLoad(EventArgs e)
  38:         {
  39:             base.OnLoad(e);
  40:  
  41:             if (!this.DesignMode)
  42:             {
  43:                 GeApp = new ApplicationGEClass();
  44:  
  45:                 GEHWnd = (IntPtr)GeApp.GetMainHwnd();
  46:  
  47:                 NativeMethods.SetWindowPos(GEHWnd, NativeMethods.HWND_BOTTOM, 0, 0, 0, 0,
  48:                     NativeMethods.SWP_NOSIZE + NativeMethods.SWP_HIDEWINDOW);
  49:  
  50:                 GEHrender = (IntPtr)GeApp.GetRenderHwnd();
  51:                 GEParentHrender = (IntPtr)NativeMethods.GetParent(GEHrender);
  52:  
  53:                 NativeMethods.MoveWindow(GEHrender, 0, 0, this.Width, this.Height, true);
  54:  
  55:                 NativeMethods.SetParent(GEHrender, this.Handle);
  56:             }
  57:         }
  58:  
  59:         protected override void OnClosing(CancelEventArgs e)
  60:         {
  61:             base.OnClosing(e);
  62:  
  63:             NativeMethods.PostMessage(GeApp.GetMainHwnd(), WM_QUIT, 0, 0);
  64:         }
  65:     }
  66: }

 

2,、NativeMethods類定義:
