Value :: size - Get size for current value
The function returns the size of the value selected in bytes. The function is mainly used for MEMO or BLOB properties in order to determine the site currently used by the value. For other data types, the function returns the the size of the property definition, which is a fixed value regardless on the instance selected.
When no instance is selected in the value handle, i.e. when the value handle is not accessible, the function trows an exception.
Notes:
In order to determine the current size of text fields, one may call String::length().
Return value: Integer value ( int32 )
The value is passed as platform independent 32-bit integer value.
