Advise Message

You can use the Advise message to receive feedback about when certain events take place, such as updates to cursor movement or presentation space. In DDE terminology, these updates are known as warm links and hot links. They allow your application to receive updated information when a specified event takes place.

Hot links update your client information automatically whenever changes occur in HostExplorer, whereas warm links require additional steps to update your client information. Hot links are used to provide continuous, up-to-date information.

Example

The following function requests feedback when the cursor changes position.

Word for Windows

Insert a field in your document by pressing the INSERT FIELD key, then Ctrl+F9.

Type the DDE command below for a warm or hot link. Do not type the curly brackets; they are simply the field-delimiter characters.

{ dde HOSTEX session name item name }
{ ddeauto HOSTEX session name item name }

Example

{ dde HOSTEX A Cursor}
