AnnGetSelectList example for C++ 5.0 and later
Note: This topic is for Document/Medical only.
For more information on declaration and unlocking procedures used in testing this example, refer to Annotation Declaration Information.
This example gets the number of selected annotation objects; then it gets an array of the selected object handles and checks to see if any of the objects in the array are polygons.
