Dynamic Data Exchange for Visual Basic 6.0 Users
Dynamic Data Exchange (DDE) is no longer supported in Visual Basic 2005.
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 backwards compatibility through Visual Basic 6.0.
With the introduction of Visual Basic .NET 2002, DDE is no longer supported. Visual Basic applications needing 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:
In addition, the Clipboard object constant vbCFLink is no longer valid.
When upgrading a Visual Basic 6.0 application to Visual Basic 2005, any code that references DDE properties or methods and any code in DDE event procedures will not be upgraded and a warning will be added.
