Public Properties

  Name Description
Public property MarkingSet Specifies the set of markings for a given string-valued property. An IMarkingSet is a container that holds all of the possible values for a particular marking-enabled property. Each IMarking object in the marking set represents a different value for the property.

You can retrieve a string-valued property's marking set by calling Get_MarkingSet() method on the IPropertyDefinitionString, IPropertyTemplateString, or IPropertyDescriptionString interfaces.

Public property MaximumLengthString Specifies the maximum length, in characters (excluding the null terminator), of a value for a property that returns a STRING data type.
Public property PropertyDefaultString Specifies the default value for a property that returns a STRING data type.
Public property UsesLongColumn Specifies whether this string-valued property is stored in a database table column as a short string (false) or as a long string (true).

Long-string table columns store their values separately from the rest of the table and therefore bypass table row-size limitations. To avoid a table's row-size limitation being exceeded, you should use a long-string column to store a large string-valued property if the database table in which it is stored has many custom properties. Because the actual text data for a long-string column is stored separately from the rest of the database row data (requiring an additional read operation to retrieve the data) you might experience a slight decrease in performance. However you might also potentially experience a system performance gain, because the overall row size for each object is reduced when long-string columns are used, therefore decreasing fetch and storage times.

Note that, unlike short-string columns, long-string columns cannot be specified in a database index.

For database-specific information about short-string and long-string table columns, see Database Engine Differences.
