TRUE | Do not allow duplicate layer names in a vector. |
FALSE | Allow duplicate layer names in a vector. |
This function returns the value of the internal setting that indicates whether to allow duplicate layer names within the same vector.
This example will call the DoModalVectorNewLayer() dialog, and return the selected values
Will not allow creation of duplicate layers.
