I'm interested to know more about the DDE capabilities of Teemtalk, with particular reference to Excel. Can you provide some info?
The TeemTalk application supports DDE and Excel. The feature and its working ways are described in the What is Teemtalk? PDF available on the Google Search. Access the results and click the first link leading to the PDF file. The information you need is described at Chapter 13. There are also examples of DDE and Excel integration.
