Opening a Project

This sample demonstrates event handling in the context of opening a project. It shows how to set the parameters for opening the project, retrieve a project interface and then open the project. This example uses the IProject81 (Open) IApplication81 (ExecutablePath) and SGWorld (OnLoadFinished) properties and methods.

 

private void OpenProject()

        {

            string tMsg = String.Empty;

 

            // A. Set Project "Open" Method parameters

            string tProjectUrl = @"C:\SomePath\SomeFile.fly";

            bool bIsAsync = false;

            string tUser = String.Empty;

            string tPassword = String.Empty;

 

            // B. Instantiate Terra Explorer Globe and retrieve Project Interface

            try

            {

                var sgworld = newSGWorld81();

                // C. Register to OnLoadFinished globe event

                sgworld.OnLoadFinished += new_ISGWorld81Events_OnLoadFinishedEventHandler(OnProjectLoadFinished);

                // D. Open Project in synchronous mode

                sgworld.Project.Open(tProjectUrl, bIsAsync, tUser, tPassword);

                MessageBox.Show("Opening project " + tProjectUrl + " in async mode");

            }

            catch (Exception ex)

            {

                tMsg = String.Format("OpenProjectButton_Click Exception: {0}", ex.Message);

                MessageBox.Show(tMsg);

            }

        }

 

        void OnProjectLoadFinished (bool bSuccess)

        {

            string tMsg = String.Empty;

 

            try

            {

                // OnLoadFinished event Received

                MessageBox.Show("Received project loaded event: " + ((bSuccess) ? "Success" : "Failure"));

            }

            catch (Exception ex)

            {

                tMsg = String.Format("OnProjectLoadFinished Exception: {0}", ex.Message);

                MessageBox.Show(tMsg);

            }

        }
