I recently started doing the DDE issue, And I have some problems.
I was able to create a server program that sends information to client.
this is a block diagram of server:
"Server " sending ITEM to Clint works perfectly.
now I try to build a SERVER that gets the ITEM from client(Inverse case)
A picture of my block diagram :
I tried to use DDE srv chaeck ithem and dde srv get dynamic items
But I can't seem to get the ITEM values from client.
What am I doing wrong?
In general, we recommend using ActiveX over DDE functions. The link below has more information:
Archived:Dynamic Data Exchange (DDE) Functions Palette in LabVIEW
Although I don't think the referred to "Using DDE in LabVIEW for Windows" document is on our website anymore, I found a copy hosted here:
Using DDE in LabVIEW (Windows Only)
hi thanks for the response.
I have to use DDE because of another app that supports only this protocol.
I saw the document you sent but not great how I can read the information that comes from the client.
See the second picture how I tried to build the block diagram (It didn't work)
I'm looking for the right way to do it, please help.
Thanks in advance
Could you kindly elaborate on what you mean by it didn't work? Are you experiencing any errors?
When I write that it is not working I mean that the server did not receive the value of item form client. I'm trying to talk to TAKAYA machine APT.(Attaches a document)
According to their document, The communications are supposed to be like this.
There are some things that are unclear to me. what this is a "open link" box?
This is what I tried to apply:
the error code is 14001
According to their document, I need to read 3 items client
IPS_item, VAL_item, LOC_item
Where am I wrong?
