Hello,

The DDE VIs are no longer in the palettes in LabVIEW since the technology is outdated.  However, you can still find the VIs in vi.lib\platform\dde.llb on Windows installations of LabVIEW.

Good luck,

P.S. - Nowadays, inter-application communication can be done with much better methods than DDE, like .NET, ActiveX, DLL calls, etc.

hi again

i got the dde vi's in the folder, can you import them into a blank vi or how can you use them?

[Darren]

Use the "Select a VI" option on the Functions palette to pick VIs out of dde.llb and add them to your main VI as subVIs.

-D

P.S. - I'm not familiar with the 3rd-party software you mention, so unfortunately I don't know if there are any other interface options besides DDE.

You can also edit your palette to show the DDE VIs.
