Chapter 3: Property Descriptions and Usage

ValidityPeriod

SMSMessage objects

Defines the time period for which the SMS message is valid, starting with the time when the SMSC receives the message. This value can be null.

The ValidityPeriod property takes a DateTime value. This example gets the value of the property from a single line edit box:

datetime dt
dt = DateTime(sle_validity.text)
g_smsMsg.ValidityPeriod = dt
