Hi All,I am trying to use Labview as a DDE client, so that i can simultaneously suck data from a number of DVM's (using GPIB) and a piece of software which suports DDE. I have managed this before using IgorPro as the client.I have set up a simple DDE-Open-Conversation, DDE-request, DDE-Close-Conversation loop. However, I get stuck at the DDE-request, and recieve this:Error 14012: DMLERR_NOTPROCESSED: transaction failed.I am dead certain that the server, topic and item names are right, as I have use them before in IgorPro. Also, using Dynamic Data Studio, I can see that the conversation is opened, and data is sent between Labview and the other software (it even looks like the correct piece of data), it just seems to be that Labview cant recognise the incoming data.Any thoughts/comments would be much appreciated.Cheers,Anna (aka FSM)

DDE Help?

I am looking to upgrade from DDE to Active X. What are the advantages and how is the coding different? I know for DDE you have to poke one cell at a time into Excel.

Hey BME Genuis,

I would recommend starting a new thread, this one hasn't been accessed since August.

With regards to Active X and LabVIEW check out this.
