Use DDE dot net

Question

Hi All

I'm using vb express 2008 I have to interface an application that use DDE vb6. How can use DDE in dot net ?

Answer 1

You can't natively. DDE is considered an obsolete technology.

It's not impossible, as the underlying Windows API calls are still available, but it isn't a simple task. You may consider creating a VB6 app that performs the basic DDE communication, then talk to that (from your .NET application) via COM.

Hi Angelwebv,

 

Welcome to the MSDN forums!

 

Dynamic Data Exchange (DDE) is no longer supported in Visual Basic 2008.
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. Visual Basic applications needing to exchange information with legacy applications that only support DDE should be maintained in Visual Basic 6.0.
