Observaciones List control with more than 10,000 elements The maximum number of elements that can be contained in a List Box control is limited only by available RAM (theoretical maximum: 2 billion lines). Nevertheless, populating a List Box control with a large number of elements (more than 10,000) affects performance.
To add a large number of elements, it is recommended to use a List Box control based on an HFSQL data file. Miscellaneous - To insert an element into a Table control, use TableInsert.
- ListInsert can be used on a "Combo Box" column in a Table control .
