Application

DDE vs. ActiveX
-
ActiveX was developed to overcome the shortcomings of DDE. DDE servers have a simple user-friendly setup but can consume a lot of system resources when handling large amounts of data. ActiveX also handles the task of helping applications communicate, but is streamlined for programs with a lot of data, like Visual Basic.
DDE Server Window
-
Sometimes programs that use DDE can stop responding. This is a result of the program unregistering a DDE server, and causes a "DDE Server Window" error message. For computers running Windows 2000 and XP, Microsoft offers a hotfix that you can download and install to remedy the problem (see Resources).
