DDE Server

Hi,
I'd like to set up a graphing program to pull some data from a labview
VI. I want to be able to just have the data pulled at the demand of the
graphing
software, so, if I'm not mistaken, I want to write a dde server. I have
some
example code on how to write a dde client, but even the user's guide has
little info on creating a server. How do I go about building one of these?
I have a rough one set up thus far, but it doesn't stay registered and it
only
runs for a little less than a second. If anyone has a place I can get a
simple
example server i'd really appreciate it. I need to build one to modify
an oscilliscope VI that I'm using right now.
Thanks, Max.

There's examples included with LabVIEW. Go to the help menu and select Search
Examples. Click on Dynamic Data Exchange for a list of example VIs. There's
a lot of different ways to get data from a LabVIEW program including DataSocket,
ActiveX, TCP/IP. You might want to look at those methods as well. NI also
has a number of examples at www.ni.com/support/epd.

Hi
I have tried to research these problems I am getting, but have not been able to resolve them.
1st is the above DDE Server Windows iTunes.exe - entry point not found.
This only occurs when I try to start iTunes.
if I click ok , several times, iTunes will start but slowly.
If at any time I have to reboot my computer I get
iTunesHelper.exe - the procedure entry point asl_add_log_file could not be located in the dynamic link library ASL.dll
if I click 3 times OK it goes away.
To this end I have uninstalled iTunes and rebooted my machine then gone to iTunes web site and downloaded the latest version.
Installing it but still get the same errors on reboot and trying to run iTunes
Anyone any ideas please.

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

How to get a DDE advise link working on a DDE server with more than one topic on the same service, and with an equal item name?

When I create a DDE server with serveral topics, all on the same service and with the same item name (different topic), it appears that an advise link does not function properly. It doesn't work at all, it update only when the advise link is terminated or only one of the topics can use an advise link.
eg.
On one DDE server I have 2 topics:
topic1:
servicename: DDEserver
topicname : C(1)
itemnames : P(1), P(2), P(3)
topic2:
servicename: DDEserver
topicname : C(2)
itemnames : P(1), P(2), P(3)
Only the topicnames differ!
Now I can't get an advise link working on one of the items (sometimes on one, but not
on another).
Normal (non-advise) links are working fine however.
(In my case there is no other solution since this DDEserver should be compatible with an older one, created earlier.)

I really don't know DDE very well. It is usually recommended that you switch to using ActiveX. You may not be correctly configuring the netDDE server. There is an example in the reource library that shows how to do this. You may also want to look at the DDE advise examples that came with LabVIEW 5.1 and earlier.

Can't print pdf docs. Keep getting failed to connect to dde server. How do I fix?

I have Adobe Reader X and I can not open files, or print them. I keep receiving a fatal error-DDE server not found. I have tried reloading Adobe, rebooted, and nothing seems to work. I have no trouble accessing my browser, can print nonadoble files. Everything else is running fine. What can I do?

Hello,
In order to change the default reader for PDF files (to not open PDF files with Firefox's internal PDF reader), follow these steps:
#Go to ''Tools'' > ''Options'' (or ''Firefox'' > ''Options'').
#In the Options window, select the ''Applications'' tab.
#In the ''Search'' field, type ''PDF''. You should find ''Portable Document Format (PDF)''.
#On the right handside you should find an ''Action'' column. Use that to select your favorite PDF reader. In order to view PDF files in Firefox, choose ''Preview in Firefox''.
Did this fix your problems? Please report back to us!
Thank you.

Adobe Reader 9.1 - Fatal Error : Acrobat failed to connect a DDE server

Hi Everyone,
I have some users telling me that when they try to open a pdf attachment in Outlook 2007. Nothing happens. The system just sits there as if you did not click on the attachment. If you wait long enought a popup box from adobe reader comes up and says:
Fatal Error
Acrobat failed to connect a DDE server.
All the PDFs are very simple, just simple scanned images or converted over from a document into a PDF.
I've tried repairing the install and still had no luck - same behaviour. The only way the pdf opens is if we go into task manager and close the AcroRd32.exe process or logoff and log back in.
If it helps, the most recent system change was the upgrade to IE7 and a new anti-virus software.
Thanks,
KEvin

No solution I am afraid but same problem, running full version of AVG and problem hit immediately after Adobe Reader 9.1 upgrade. Pretty darn sure problem is in the upgrade but the relevant Restore Point was overwritten before I figured it out. Any advice welcome.

Windows 7 64 bit apps crashing, dde server error

Hi, I am having problems with a new Windows 7, 64 bit system. Acrobat 9 frequently crashes programs when it's invoked, for instance when trying to print a web page to PDF from Firefox, or making a PDF from a Word document. Firefox or Word will crash, with no errors. Acrobat is also giving these errors freqently: "Fatal error: failed to connect to dde server"
Other installed apps include MS Office 2007 and Symantec Endpoint Protection, SAS JMP, Endnote.
thanks for any suggestions.

Failed to connect to DDE Server Acrobat XI Pro Windows 8.1

I had installed Acrobat XI Pro on a Windows 8.0 notebook computer and it was working fine. When I upgraded to Windows 8.1 a few months ago, I started getting intermittent problems/error messages when I would try to open a pdf file by doubleclicking on the file either in a folder or on the desktop. The file wouldn't open and the error message was "Failed to connect to DDE Server." I can still open the files by doing a File, Open from inside the software, so it's not an insurmountable problem, just annoying. Any suggestions on how to fix this?

Hi TreeLady ,
Thanks for posting on forums, DDE server was a part of Windows XP, it was removed from Windows Vista and above. However, if you are getting this error in Acrobat, try the following.
(This error occurs when you have more than 1 process of Acrobat running)
1) Go to the task manager by presiing Ctrl+Alt+Del
2) Go to the processes in Task Manager
3) End all processes related to Acrobat
4) Launch Acrobat again.
Also, to find the root couse or to isolate the issue you can try the following.
1) Click on start
2) Type RUN
3) Type MSCONFIG
4) Go to services
5) Hide all Microsoft services
6) Disable all Services (Except Microsoft)
7) Restart your machine
8) Launch Acrobat to check if you get the issue.
This would help us to understand if Acrobat or any other third party process is not allowing Acrobat process to end causing a conflict .
Thanks,
Vikrantt Singh

Can't open file ... error msg "cannot connect to DDE server"?

I can't open my pdf files from Outlook or just open Acrobat. If it does open, it says Acrobat failed to connect to DDE server? I'm using Acrobat Pro 9.3, I think as it updated. I have Win7 with current updates on a new Sony Vaio laptop.
I looked at the other msgs but I am using Norton Anti-Virus not the one mentioned. I am upgraded to Win7 and IE8. All worked ok before switching to new computer and in starting to use Win7 & IE8.
Thanks!

Adobe Reader XI - Fatal Error Acrobat failed connect DDE Server

Hallo zusammen.
Mein System ist:
Windows XP SP3
Adobe Reader XI (11.0.3)
Outlook 2010
Exchange 2010
Antivirus: Avast Endpoint Protection Suite Plus
Alle User haben ein Firmenprofil
Der "Problemuser" arbeitet an zwei PC's mit Windows XP SP3 -> Profil wurde komplett erneuert
PC HP Compaq 6300 Pro (Businesspc) -> wurde vor 1 Woche neu installiert
Seit ein paar Wochen hat einer unserer Userin das Problem dass wenn sie normal mit Outlook arbeitet und Lieferscheine bekommt, öffnet sie diese und druckt sie aus. Doch nach ein paar Stunden arbeiten tritt immer wieder der nachfolgende Fehler auf. Sie klickt auf das PDF und bevor das PDF sichtbar ist erscheint folgender Fehler:
Fatal Error
Acrobat failed to connect to a DDE server.
Sobald sie den Reader schliessen möchte, passiert nichts. Der Reader schliesst sich nicht. Sogar den Prozess schliessen geht nicht. Nur ein Neustart hilft noch.
Manchmal kann sie das PDF öffnen und lesen und der Reader lässt sicht dann aber wie oben beschrieben nicht schliessen (Fehlermeldungslos).
Wie kann ich das mit dem DDE Server beheben? Ist ev. ein Port beim Antivirus geschlossen welcher offen sein sollte?

Fatal Error: Failed to connect to DDE server

I've read the other posts about this problem, but none seem to fit my situation.
This happened while trying to use a 3rd party program Typhoon AutoRun to test autorun files for CDs of our Ebooks that we're burning. Each of these Ebook CD projects has 6 PDF files to open; 1 Mobipocket, 1 HTML. Of course, the only problem occurs with the PDF files.
Let me start by saying that I was using Acrobat 6 until September, when we upgraded to CS 4, and never experienced this issue.
And after installing Acrobat Pro 9, I hadn't any difficulty until TODAY.
Order of events: I opened a past completed project in Typhoon Autorun to test the file before burning to CD.
When I clicked on one of the PDF document buttons, the first thing that happened was Adobe Active X 9 attempted to run. BUT the Active X failed to install on the first attempt:
"Error 1904.Module
C:|WINDOWS\system32\Macromed\Flash\Flash9f.ocx failed to register. HRESULT -2147220473. Contact your support personnel."
The Typhoon Autorun program continued operating and opened the project's PDF documents without any difficulty -- all 6 opened, one after the other, when I clicked on their buttons.
I closed out the error message, closed out the Typhoon Autorun project I was testing to work on another Typhoon Autorun project. When I had that one finished, I tested it as I had the one previous.
This time when I clicked on a button to open one of the PDF button, the Adobe Active X 9 program loaded and INSTALLED successfully.
THEN, the PDF document opened. But when I attempted to open any of the other 5, they did nothing. I double-checked my Typhoon Autorun project files, but all of the settings were correct. I tried testing my project again. This time NONE of the PDF files would open.
I closed the Typhoon Autorun program and attempted to open Acrobat Pro 9 immediately after. I tried clicking on the shortcut button several times with no result. After several minutes, literally, I received the "Fatal Error: Failed to connect to DDE server" --- actually, several instances of that message to correspond with all the times I'd attempted to open the program.
I shut down my computer, rebooted, reopend Typhoon Autorun and tried to test a different project.
Again, Adobe Active X 9 installed. (If it's already installed why is it reinsalling???)
And again, only 1 PDF file would open. Then none of the others. I shut down Typhoon Autorun and tried to open Adobe Acrobat again, and it wouldn't open.
The problem seems to be appearing when Adobe Active X 9 installs, and it's doing that automatically, without asking.
I never had this problem when I used Adobe Acrobat 6 (I'm really beginning to regret upgrading)
I never had this problem before this Active X 9 started installing.

Cannot open PDF as cannot connect to DDE Server

DDE Server in Labview

I have been trying to operate Labview as a DDE server so that another application can conneect to it.
(1) I don't understand how you access data that is provided to Labview by the client
(2) Is the data that is set in the set block the data that is accessed by using the topic string?
I have been through the examples and documentation and i didnt find an answer for question 1. With question 2 i am just looking for confirmation on how the client accesses the data because i havent actually got it to work yet. DDE is the only method that i am aware of with the program that i am using as the client.
Thanks,
Tom

Hi Tom,
Here is some example code that shows how to use DDE to read and write to an Excel spreadsheet. Perhaps it will give you a good starting point. Also, as Mike said, if you can use OPC you may want to consider it.
Good luck!
