DDE palette broke

[Vinc42]

Hello everyone,

I know that DDE is an old technology, but I still hope that a solution can be found for my problem.
I use DDE to communicate with a device. So far it has worked well. Now the DDE VIs are suddenly no longer executable.

The error messages are as follows:
Code interface node: Error integrating a subroutine
Details: The external subroutine could not be found.

Code interface node: Object code was not loaded
Details: This code interface node does not contain any code. You can load the file with the object code (*.lsb) by right-clicking on the node and selecting "Load code resources".

I am using LabVIEW 2019 32bit, on Win10.
Recently windows tried to update to Windows 11, but it did not work. I suspect there is a connection. However, I have not noticed any other functional impairment.

I use this combination too!

Following this article I could locate the DDE functions and they are still executable for me…

Hi Gerd,

Thank you for your Answer. I found this article too, but it does not describe my problem.

My Problem was that the DDE VIs themselves were not executable.

I reinstalled LabVIEW and now it seems to be working again.

I have no idea what windows update did to screw up my installation 😒

Vinc
