The LISTBOX Get locked columns command returns the number of locked columns in the list box designated by the object and * parameters.
If you pass the optional * parameter, this indicates that the object parameter is an object name (a string). If you do not pass this parameter, this indicates that the object is a variable. In this case, you pass a variable reference instead of a string.
Columns can be locked through the Property List or using the LISTBOX SET LOCKED COLUMNS command. For more information, refer to the Design Reference manual.
If a column is inserted or deleted by programming within the locked area, the number of columns returned by this command takes this change into account. For example, if you delete a locked column, the number of locked columns is decreased by 1. Similarly, if you insert a column by programming into a locked area, this column is locked automatically and the number of locked columns is increased by 1.
However, the command does not take into account the visible/invisible status of columns.
