Dynamic Data Exchange (DDE) Links
Using DDE links, you can paste text into a DGN file. A linked item is automatically updated in the DGN file when the originating file is changed in the source (or server) application.
- If text is pasted with a DDE link and both the source application, such as a spreadsheet program, and OpenPlant PID is running, changing the object in the source application causes the linked object in OpenPlant PID to change automatically.
Note:
OpenPlant PID identifies linked objects by filename.
If an object is not a saved file when it is pasted in a model,
OpenPlant PID may not be able to locate it
later. For example, if you create text in an
“untitled” document and paste the text before you save
the file,
OpenPlant PID does not know where to find
the linked text.
If you paste an object with a DDE link and if OpenPlant PID displays an alert box with the message “ OpenPlant PID requested server is not responding,” you should confirm the following:
- All source applications are located in the proper directories.
- The directories for the server applications are included in the operating system's PATH environment variable.
