LlEnumGetFirstVar Method

In This Topic

Returns an iterator for the first variable. The name does not have to be known, the variables are returned in the order in which they are declared to List & Label.

You should avoid using this function directly - the Variables property and it's counterparts for fields and chart fields offer you a much more powerful way to work with your data.
