• Initializing a new event message structure with the Initialize method

Attention: You must call the Initialize method before you can perform any further manipulation on a new WF_EVENT_T object.

• Initializing a CLOB locator

• Writing a text variable into a CLOB variable

• Setting the content attributes of the event message structure with the Content method

• Setting the address attributes of the event message structure with the Address method
