Custom command cannot create New Project

The following custom command always throws an exception.



using System;

using System.Collections;

using System.Windows.Forms;

using Sony.Vegas;



public class SampleModule : ICustomCommandModule

{

    protected Vegas myVegas = null;



    public void InitializeModule(Vegas vegas)

    {

        myVegas = vegas; 

    }



    public ICollection GetCustomCommands()

    {

        CustomCommand cmd = new CustomCommand(CommandCategory.Tools, "NewProjectBug");

        cmd.DisplayName = "NewProjectBug";

        cmd.Invoked += this.HandleInvoked;

        return new CustomCommand[] { cmd };

    }



    void HandleInvoked(Object sender, EventArgs args)

    {

        using (UndoBlock undo = new UndoBlock("NewProjectBug"))

        {

            try

            {

                // This generates an exception

                Project project = new Project();

            }

            catch (Exception e)

            {

                MessageBox.Show(e.Message);

            }

        }

    }

}

Any ideas what could be going on?

Solution is to move new project creation outside of undo block.

"NewProject" is not undoable. Therefore it needs to be done OUTSIDE the "undo" block. This will work:



    void HandleInvoked(Object sender, EventArgs args)

    {

        Project project = new Project();

        using (UndoBlock undo = new UndoBlock("NewProjectBug"))

        {

            try

            {

                // Whatever you do IN the new project.

            }

            catch (Exception e)

            {

                MessageBox.Show(e.Message);

            }

        }

    }
