Select All in Part, Assembly, or Drawing (VB.NET)

This example shows how to select everything in the graphics area of a part or assembly document or in the sheet of a drawing document, as if you box-selected everything in the graphics area or the sheet.

'--------------------------------------------------------------------------
' Preconditions:
' 1. Part, assembly, and drawing documents opened by the macro
'    exist.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Examine:
'    * Sheet to verify that all of the entities in the drawing
'      are selected.
'    * Immediate window to see how many entities are selected.
' 2. Click Window > bolt-assembly.sldasm to switch to the assembly
'    document.
' 3. Examine:
'    * Graphics area to verify that the all of the components
'      in the assembly are selected.
'    * Immediate window to see how many components are selected.
' 4. Click Window > bolt.sldprt to switch to the part document.
' 5. Examine:
'    * Graphics area to verify that the all of the edges
'      in the part are selected.
'    * Immediate window to see how many edges are selected.
'
' NOTE: Because these documents are used elsewhere, do not save changes.
