- MORE INFORMATION
- ================
-
- The DDESPY tool demonstrates how to monitor DDE messages by setting up an
- APPCLASS_MONITOR callback function. The DDESPY-monitored data can be
- selected and filtered through various options. The information is
- represented in up to four selectable tracks for String Handles,
- Conversations, Links and Services, each displayed in different overlapped
- windows. DDESPY records the messages and displays them on the related
- window. DDESPY is useful in debugging to verify DDE data and messages.
-
- DDESPY demonstrates the following techniques:
-
- - Using a DDE APPCLASS_ MONITOR.
- - Using a DDE callback routine.
- - Creating ownerdraw multi-column list boxes (sorted by column).
- - Creating a string class window to spool endless text.
-
- To use DDESPY to monitor messages, do the following:
-
- 1. Choose the Outputs menu to select the Output device.
- 2. Choose the Monitor menu to select the data you wish to monitor.
- 3. Choose the Track menu to select the track to be displayed.
- 4. Install a client server DDE conversation, such as \ddeml\client and
- \ddeml\server.
