Dynamic Data Exchange Changes in Visual Basic .NET
Dynamic Data Exchange (DDE) was an early technology that enabled the exchange of information between applications in Visual Basic 3.0. DDE was replaced by OLE Automation in later versions of Visual Basic; however, DDE was still supported for backward compatibility through version 6.0.
With the introduction of Visual Basic .NET, DDE is no longer supported. Visual Basic applications that need to exchange information with legacy applications that only support DDE should be maintained in Visual Basic 6.0.
The following DDE properties, methods, and events are no longer available:
- Properties
- LinkItem
LinkMode
LinkTimeOut
LinkTopic
- Methods
- LinkExecute
LinkPoke
LinkRequest
LinkSend
- Events
- LinkClose
LinkError
LinkExecute
LinkNotify
LinkOpen
In addition, the Clipboard object constant vbCFLink is no longer valid.
