DDE Info dialog box
Go Up to Property Editors Index
Use the DDE Info dialog box to specify, at design time, a DDE server application and a topic for a DDE conversation.
To open the DDE Info dialog box:
- Place a DDEClientConv component on the form.
- With the component selected, do one of the following:
- Click the ellipsis button in the Value column for the Vcl.DdeMan.TDdeClientConv.DdeService property or Vcl.DdeMan.TDdeClientConv.DdeTopic property.
- Double-click the Value column for the DdeService property or DdeTopic property.
DDE Info options
The following options are available in the DDE Info dialog box:
Dde Service
Specify the server application for the DDE conversation. The application you specify is entered into the Value column for the DdeService property.
You do not need to specify an extension for the server application.
If the directory containing the application is not on your path, you need to specify a fully qualified path.
Dde Topic
Enter the topic for a DDE conversation. The topic is a unit of data, identifiable to the server, containing the linked text. For example, the topic could be the file name of a spreadsheet.
When the server is a VCL-based application, the topic is the name of the form containing the data you want to link.
If the directory containing the topic is not on your path, you need to specify a fully qualified path.
Paste Link
Click Paste Link to paste the application name and file name from the contents of the Clipboard into the App and File edit boxes.
This button is active only when the clipboard contains data from an application that can be a DDE server.
