field- The name of the widget to receive server data.

- 1 Success.
sm_dde_client_paste_link_coldrequests a cold DDE paste link between a widget and a server application. Panther gets the clipboard data and its source—server, topic, and item. Subsequent requests to update data use this source information to get new data from the server. Given a cold paste link, the server does not notify the client Panther application of changes to linked data. The application must explicitly request data updates by calling sm_dde_client_request.Before creating a paste link, two conditions must be true:
- The clipboard must contain data copied from the server.
Panther checks whether a connection to the server application already exists—for example, another open screen has a link to this server. If no connection exists, Panther attempts to establish one. After Panther verifies or establishes a connection, it creates a cold link between the widget and the data source.
This function can succeed only if the server application is already running; otherwise Panther posts an error message. If the link cannot be created, Panther posts an error message.
