PROPERTY_TO_BLOB Function

Syntax

Data as B = PROPERTY_TO_BLOB(P source[,C fields])

Arguments

source: The name of a dot variable. Pointer
fields: Character

Description

Dump pointer contents (can be variable frame) to a blob - optional limit to 'fields'.

Discussion

The PROPERTY_TO_BLOB() function converts a "dot" variable to a blob variable. Fields is the dot variable's root name. The dot variable can be of arbitrary complexity. Once a dot variable has been converted to a blob, it is easy to save, in effect, saving the current values of all of the dot variable's sub-elements. The PROPERTY_FROM_BLOB()function allows you to restore a dot variable and all of its sub-elements from a string that was previously created using PROPERTY_TO_BLOB().

Example

For example, assume that you have this "dot" variable:

dim p as P
dim dat as B
p.lastname = "smith"
p.firstname = "john"
dat = property_to_blob(p)
