OLE Automation Sample 
 
 
SUMMARY 
======= 
 
The SPoly sample draws polygons. The only way to make SPoly draw a polygon  
is to use its programmability interface. 
 
One OLE automation object is exposed by Spoly: spoly.application. 
The object spoly.application is associated with SPoly's main application  
window. It controls drawing polygons and clearing the display. 
 
MORE INFORMATION 
================ 
 
SPoly implements IDispatch for spoly.application. 
 
Methods defined on spoly.application 
----------------------------------- 
 
Name                        Description 
 
Draw                        Draw the polygon. 
Reset                       Delete all points from the polygon. 
AddPoint(X, Y)              Add a point with coordinates (x,y) to the  
                            polygon. 
EnumPoints as VT_ENUM       Return a collection of the polygon's points. 
GetXOrigin as short         Get the X origin of the polygon. 
SetXOrigin(x as short)      Set the X origin of the polygon. 
GetYOrigin as short         Get the Y origin of the polygon. 
SetYOrigin(y as short)      Set the Y origin of the polygon. 
GetWidth as short           Get the line width of the polygon. 
SetWidth(width as short)    Set the line width of the polygon. 
 
Shortcomings of this sample 
--------------------------- 
 
Many items in this sample should be properties. Instead, they are  
implemented as methods. Anything that behaves like an attribute of the  
object should be a property. 
 
This is not a good example of how to implement a collection.
