Description
Part one of the DDE three-level hierarchy. Used in conjunction with DDETOPIC to establish a DDE connection. Specifies the application that is to function as server.
Usage
existingprop = Set_Property (objectname, "DDESERVICE", application)
serviceapp = Get_Property (objectname, "DDESERVICE")
Remarks
Values passed in Set_Property:
| Value | Description |
|---|---|
| application | DDE name for an application to function as server. Typically, this is the name of the *.EXE file. |
Returns
Values returned by both Get_Property and Set_Property:
| Value | Description |
|---|---|
| serviceapp | Name of current server application. |
| Existingprop | Current server application, when Set_Property was run. |
Each DDE server-capable application has a specified name to which it responds when DDE service is requested. Typically, this is the name of the *.EXE file, but check with the server application for more details.
When DDESERVICE is set, the system will check to see whether DDETOPIC is also set (non-null value). If so, the system will terminate any existing connection, and will attempt to establish a DDE conversation for the specified Service/Topic pair. If DDESERVICE is not set, then setting DDESERVICE will terminate any existing connection, and store the service name, without attempting to establish a connection.
