DDESpy can display DDE information in a window or on your debugging terminal or can save the displayed information in a file for later use.
You use the Output menu to select where DDESpy is to send output. If you choose the File command, you must specify the name of an output file. After you have chosen the File command once, DDESpy prompts you for an output filename every time you restart the application.
From the Output menu, you can choose to send your output to either a debug terminal or to the DDESpy window. You can also choose the Clear Screen command to clear the display window. Use the Mark command to add text to the display as a marker — for example, before a DDE event to make it easier to find the event in the output file.
