What is DDE?

Other than Donkey Dicked Elephants?

I was having issues with email attachments opening slower than hell and goggled around and found out that I needed to turn of “DDE” under file types and the open command.

what is this crap, and why would it have turned itself on (I’m sure it is something I installed that switched it)

Much nicer now that I figured it out. I did a quick google and couldn’t find a succinct answer, if you google a better one post it up supernerds.

Dynamic Data Exchange.

Dynamic Data Exchange (DDE) is a standard inter-application communication protocol built into Microsoft Windows operating systems and many applications that run under Windows NT support it. DDE takes data from one application and gives it to another application. It allows Windows NT programs that support DDE to exchange data between themselves.

Edit: I just happend to be digging through dde help files trying to get Excel to write data to a PLC.

Could be anything from pulling data from a server or remote source to having enhanced documents that have dynamic data that updates when its source updates.

Why would I want this option fagging up my normal operations though? It made everything open slow as shit.

DDE has never been reliable and can become corrupted like everything in Windows. Loading documents starts loading the DDE DLLS and extensions and poof. if you aren’t opening office documents that are using the features of it, just keep it off.
