<h1>Insert SimpleNote Example (C#)</h1>
<p>This example shows how to insert and change a SimpleNote in a drawing document.</p>
<pre>//--------------------------------------------------------------
// Preconditions:
// 1. Create a C# Windows console project.
// 2. Copy and paste this example into the C# IDE.
// 3. Add a reference to:
//    <i>install_dir</i>\<b>APISDK\tlb\DraftSight.Interop.dsAutomation.dll</b>.
// 4. Add references to <b>System</b>, <b>System.Runtime.InteropServices</b>,
//    and <b>System.Windows.Forms</b>.
// 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.
