LlEnumGetFirstVar Method


combit.ListLabel25 Namespace > LlCore Class : LlEnumGetFirstVar Method

flags for the allowed types of fields (to be .or.ed):

LL_TEXT, LL_BOOLEAN, LL_BARCODE, LL_DRAWING, LL_NUMERIC, LL_DATE, LL_RTF, LL_HTML, LL_TYPEMASK (to iterate all of them)

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.
