Insert SimpleNote Example (C#)

This example shows how to insert and change a SimpleNote in a drawing document.

//--------------------------------------------------------------
// Preconditions:
// 1. Create a C# Windows console project.
// 2. Copy and paste this example into the C# IDE.
// 3. Add a reference to:
//    install_dir\APISDK\tlb\DraftSight.Interop.dsAutomation.dll.
// 4. Add references to System, System.Runtime.InteropServices,
//    and System.Windows.Forms.
// 5. Start DraftSight and open a document.
// 6. Start debugging the project.
//
// Postconditions: 
// 1. A message box pops up when a SimpleNote is
//    inserted in the drawing.
// 2. The selection filter is set to select SimpleNotes only and
//    is activated.
// 3. The SimpleNote is selected and its text changed. Examine 
//    the drawing to verify.
