DDE - is it available in .NET?

[Guest]

Hi all,


Is DDE still available in .NET? Is there a way to send DDE commands through
VB.NET?

Do I need an ActiveX component, or is there something in the .NET API or
Win32 API that I can use?

Damn - the code is ugly ... I expected that ... but thank you ;-)

;-) Note that DDE is not supported by .NET out of the box because it is
considered a "legacy technology".

I know... <sigh> but I have a requirement to hook into an app that looks
like it's been around since Windows 3.1 (or older!) :S

Hey, it was only a proof of concept What do you expect for public
domain ;-)

Before you ask, it still works with .NET 2.0.

Hi Mark,

I should have clarified the amount of marshaling between win32 apis -> .NET
is ugly :S

In anycase, thank you for building a proof of concept - I'm VERY glad you
did. I hope you didn't take my comments in the wrong way ... I appreciate
your code

When using DDE solutions, keep in mind that NetDDE is not supported
anymore on Vista.

There are now code examples out there that use DDEML, which will reduce
that (but I can't find the free ones at the moment).

It looks like I did, but that's OK. (You did see the emoticons through
out?)

I'm sarcastically challenged - I need subtitles.

I'll check out DDEML. Thanks again!

Thanks for the alert about Vista.

Sorry for the late response. I maintain an open source DDE library for
the .NET Framework. You can find it at the following link.
