L_UINT *puGapNodes;	/* address of the variable to be updated */

Gets information on how to display the nodes of the annotation object in design mode.

Parameter	Description
hObject	Handle of the annotation object.
pbShowNodes	Address of the variable to be updated with a value that indicates whether to show the nodes. Pass NULL if you do not wish to retrieve this information. Possible values are:
	Value	Meaning
	TRUE	Show the nodes.
	FALSE	Do not show the nodes.
puGapNodes	Address of the variable to be updated with a value that represents the number of nodes to skip before displaying another node (Pass NULL if you do not wish to retrieve this information). Possible values are:
	Value	Meaning
	0	Show every node.
	1	Show a node, skip a node, show a node

Comments

This function is valid for the following annotation objects:

Curve

Closed Curve

Freehand

Freehand Hotspot

Polygon

Polyline

In addition, the Automation object stores node settings along with the other object default settings

Note:

The last node is always shown. Therefore, using a large value for uGapNodes will probably result in only the first and last nodes being shown.
