• Download and install TerraExplorer Plus.
• Create a new Windows Forms Application project in Visual Studio, using either C# or VB.Net:
  • In Visual Studio, select File> New> Project.
  • If you want to create a C# project: Select Visual C#> Windows> Windows Forms Application.
    Name the project TerraExplorerShowcase, and click OK.
  • If you want to create a Visual Basic project: Select Visual Basic> Windows> Windows Forms Application.
    Name the project TerraExplorerShowcase, and click OK.
• Add TerraExplorer ActiveX objects to the Toolbox.
  • In Design view, right click the Toolbox, and select Choose Items.
  • Click the COM Components tab and select the TE3DWindow Class, TEInformationWindow Class and TENavigationMap Class check-boxes.
  • Click OK. Three icons are added to your toolbox: the 3D Window, the Information Window and the Navigation Map controls.
• Add a 3D Window to the form.
  • Click the 3D window control icon in the toolbox and drag it to the required location on your form.
• Reference TerraExplorerX COM dll.
  • From the Project menu, select Add References.
  • Click the COM Components tab and locate TerraExplorerX 1.0 Type Library from the available references.
• Add the using directive for TerraExplorerX namespace in the Form1 code.
  • using TerraExplorerX;
• Define a variable to hold an SGWorld object instance.
  • Note: You will use this variable later to access extensive TerraExplorer API.
  • private SGWorld66 sgworld;
• Initialize an SGWorld object.
  • Note: This object will automatically find the ActiveX control that you have placed on the form and interact with it.
  • Note: You should initialize this object only after the ActiveX object was already created, i.e. after the call to InitializeComponent() in the constructor.
  • sgworld = new SGWorld66();
• Now you can use SGWorld object to control the TerraExplorer ActiveX. The following code loads a .fly project and flies to a specific location.

      public partial class Form1 : Form
      {
          private SGWorld66 sgworld;
          public Form1()
          {
              InitializeComponent();
              sgworld = new SGWorld66();
          }
   
          private void Form1_Load(object sender, EventArgs e)
          {
              // Register to OnLoadFinished globe event
              sgworld.OnLoadFinished += new _ISGWorld66Events_OnLoadFinishedEventHandler(OnProjectLoadFinished);
              // Open Project in asynchronous mode
              string flyFile = "https://www.skylinesoft.com/SkylineGlobe/WebClient/PresentationLayer/WebClient/SkyglobeLB.fly";
              sgworld.Project.Open(flyFile, true, null, null);
              MessageBox.Show("Opening project " + flyFile + " in async mode");
          }
   
          void OnProjectLoadFinished()
          {
              MessageBox.Show("Received project loaded event. Click OK to fly to  Washington DC.");
              IPosition66 Washington = sgworld.Creator.CreatePosition(-77.036667, 38.895111, 1500, AltitudeTypeCode.ATC_TERRAIN_RELATIVE, 0, 0, 0, 0);
              sgworld.Navigate.FlyTo(Washington);
          }
      }
