UDP communication with Lingo

Hello,
does anyone know some good free Xtra for UDP communication? Multiuser.xtra (with SMUS) not work for UDP when server is behind router. Another TCPUDPXtra I found not work in browser ...
Is another way how create simple fast UDP communication?
Thnak you.

If you are talking about two web browser sessions on the same machine, and the same browser i.e both netscape or both i.e then use a static method and a singleton class. If you want a more detailed explanation, please ask.

UDP communication with Raspberry Pi

Hello,
I am developing an application that needs to communicate a simulink model running on a RaspberryPi with a LabVIEW program executed in a PC.
I managed to send data from the LabVIEW to Simulink, but I am not beeing able to make it run the other way.
I have done a simple Simulink model and LabVIEW program to check the communications and is it working if I run both in the PC. However if I run the Simulink model in the Raspberry there is no communication.
Any idea which can be the problem?
Thank you,
Mikel

I can't tell you what your problem is because I don't know your network or hardware config, but you can at least save yourself some trouble by putting wpa_supplicant.conf in /etc , since that's the default location it'll read it from, so you can just run "dhcpcd wlan0" to test it instead of having to invoke the file manually all the time.

UDP communication through proxy

Hello,
I've been struggling for hours now trying to work out how to use UDP communication through a proxy. It took me quite a bit of work to get it working for HTTP, but it's working fine now.
I'm trying to use the DatagramSocket class and there's no option to use a proxy anywhere. I tried setting the proxy globally by doing:
properties.put("proxyHost", "proxyAddress");
properties.put("proxyPort", "proxyPOrt");
properties.put("proxySet", "true");
but it doesn't work. I get errors on name resolution when I try to connect.
I'm looking for a global (programmatical) way to set up the proxy, so that I can use the InetAddress too to get IP addresses and such.
Cheers.

properties.put("proxyHost", "proxyAddress");
properties.put("proxyPort", "proxyPort");Those two properties are just equivalents for http.proxyHost/proxyPort. They come from the defunct HotJavaBean (1997-8) and somehow leaked into the JDK, maybe because books of the era mistakenly documented them as part of the JDK, or maybe because part of the HJB implementation leaked into Java.
properties.put("proxySet", "true");That property has never done anything in the JDK. It did something in the HJB which is no longer with us ...
There is no support for UDP proxying in Java.
but it doesn't work. I get errors on name resolution
when I try to connect.That's a DNS topology issue, nothing to do with proxying really.

Sir i am using datasocket read ,i am communicating with java but my problem is that bcz im using while loop to see if value has changed my labview consumes all the processors time ,sir i want a event like thing so that while loop is not in continuous loop

sir i have given lot of effort but i am not able to solve my problem either with notifiers or with occurence fn,probably i do not know how to use these synchronisation tools.

I want to pass along a couple of tips that will get you more and better response on this list.
1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
4) If you have a question first search the examples for something tha
t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"
Trying to help,

I get an error message when trying to install windows 7 on my macbook pro. The message says "windows has encountered a problem communicating with a device connected to your computer. I don't have anything connected to my computer. How do I fix this?

I'm trying to install windows 7 on my macbook pro. I went through the process of bootcamp telling it to install windows 7. Once the windows boot manager started an error message came up. The error message says " windows has encountered a problem communicating with a device connected to your computer. I don't have a usb connected to my computer. I am using windows 7 professional install disc. I can't figure out what i am doing wrong. The same message keeps coming up over and over. Am I doing something wrong or is it something else?

Well, shucks, i just spent almost 30 minutes trying to find your model user guide to explain it better, I guess they never got around to making it.....
I would just borrow another Windows disk and try installing it again and if it does it again then you might take it to an Apple Store and see if one of the "Genius' " can figure it out.
Make sure your internet is enabled and click on your blank desktop and at the top of your screen is a Help menu option, enter PRAM and it should give you a list of things relating to Pram. It may take a few seconds to list anything as it has to connect to Apples severs first. It should list the things you may have to fill back in when your done.
"P-ram" stores some common information that is used in the background, your date, time, startup disk, etc, that you don't have to re-fill when you restart, it's a little different for each computer.

"The software required for communicating with the iPod is not installed..."

I realize my explanation of my problem is long-winded, so if you want a shortened version, here it is:
I've followed all the instructions trying nearly everything, and no matter what I do, iTunes gives me the error saying: "The software required for communicating with the iPod is not installed correctly. Please reinstall iTunes to install the iPod's software." My G5 iPod (60GB) works on two other computers (both without any music on them), so I assume there something wrong with my computer and not the iPod itself.
Now for the long-winded story of the last eight hours of my life...
I just got the Generation-5 iPod Video (60GB) a today and I'm having problems already. I followed the instructions and installed the iPod software and then plugged in my iPod (iTunes has been on my computer for a while now). I was expecting iTunes to open after plugging in the iPod, but my device manager only detected and installed "a new device". I manually opened iTunes and got an error saying: "The software required for communicating with the iPod is not installed correctly. Please reinstall iTunes to install the iPod's software."
After re-installing the iPod software and iTunes, and restarting my computer countless times, I came looking for help here. I found this page, which seemed to outline my problem exactly. My computer recognizes the iPod as a drive, but iTunes won't have anything to do with it. I have all the symptoms outlined in the heading, so I hoped to solve my problem there. I followed the instructions step-by-step, and after the final restart, I open iTunes to get the same exact error message.
I decided to determine whether there was a problem with my iPod or if it was my computer. I plugged my iPod into my uncles's powerbook, and got to the point where I can name and configure my iPod. I expected it to work flawlessly on a Mac (which it did) but there is no way for me to continue using a Mac (after tomorrow) for my iPod. This formatted the iPod for a Mac, so I went to another (different from the original) Windows computer, clean of any iTunes and iPod software, and followed the instructions exactly as they're supposed to be followed. After the installations, I plugged in my iPod, and although iTunes didn't open, I was able to format back to Windows and name my iPod (a step in the right direction). I should note that my (anti-iPod) computer is a Windows XP Pro, and the working one is Windows XP Home Edition. This was all well and good, until I remembered there was no music on this computer. So my iPod is completely working there, but there isn't anything I can do with it.
Next, I came back here and browsed around the discussion boards, hoping to find somebody with a similar problem to mine. There seems to be alot of errors concerning iTunes not recognizing the iPod, but none of the solutions I tried worked for me, including changing the drive letter. I get the "iPod Service Error" while trying to restore to factory settings through iPod updater.
Of course, I could transfer all 32GB of music from one computer to another, but the second (working) computer isn't mine and I won't have access to it in a couple months. It would be most convenient if I could get my iPod working on my own computer. Any help would be appreciated, especially from somebody who has solved this problem or know how to solve this problem.
P.S.
Here are some other minor details that my be important, but I didn't feel they were worth including.
- My brother has his iPod mini set up on my computer, under a different user login. He gets the same error once in a while, but re-installing iTunes always solves the problem for him. I had him try solving my problem his way, but nothing worked for him either.
- My computer is an AMD Athlon 64 Processor 3200+, 512MB RAM with Windows XP Pro SP2 installed. My internal hard drive is partitioned, using the letters C, D and H (C being my system files, D used for recovery files and H for my applications and games). My E drive is used as a DVD/CD-ROM Drive, and drives F and G are reserved for virtual drives (none have been running during this entire ordeal). My external hard drive uses the letter I, and I manually set my iPod to use the letter J (I've never used 'J' for anything else before).
- Yes, I have downloaded and installed the latest versions of iTunes and the iPod software.
- I'm assuming there is a problem with my computer and not my iPod, since it worked on both other computers I tried. I'm hoping it's as simple as changing a registry file or cleaning out (yet another) temp directory.

Solution to "Software required for communicating with the iPod is not installed"!
I battled this same problem for about 5 hours. Going through re-installations, the "5 R's", all these discussion boards. Nothing worked.
The problem is that iPodService was repeatedly crashing after minute or so. You can verify this by hitting Ctrl-Alt-Delete and noting that iPodService is missing from the process list (sort by image name), or by right-clicking on My Computer and selecting "Manage", then going to Services and checking out the IPodService service - if it gives you the option to "Start", then it's not running.
Here is what worked.
1. De-install iTunes and iPod (if you have the updater installed) completely by going to Start --> Control Panel --> Add/Remove Programs. Also delete the C:\Program Files\iTunes and c:\Progam Files\iPod\bin directories. (Don't worry, this doesn't affect your saved music files.)
2. Log in as an Administrator
3. Go into the registry (note this is dangerous - you should be careful) and remove the iPod entries that the uninstaller misses.
3.1 Go to Start menu --> Run.
3.2 Type in "regedit".
3.3 Go to HKEYCLASSESROOT --> IPodService.iPodManager.
There are two keys here, iPodManager and iPodManager.1. In my case, I did not have permission to view either of these. I think this is the root cause of the problem. I think the installer can't properly update these because it doesn't have permission. So you need to change the permissions:
3.4 Right-click on IPodService.IPodManager
3.4.1 Select "Permissions..." A warning will appear saying you don't have permission, but that you can change permissions.
3.4.2 On the window that launches, click on "Advanced..."
3.4.3 Click on the "Owner" tab.
3.4.4 Select a valid account (the one you're logged in under) under "Change Owner To".
3.4.5 Hit "OK".
3.4.6 Back on the main Permissions window, hit Add and add the same account as a valid user.
3.4.6.1 Where it says "Enter the object names to select", type in the account name, e.g. "Smith".
3.4.7 Click on the "Allow" checkboxes for "Full Control" and "Read".
3.4.8 Hit "OK".
3.5 Repeat procedure for the "iPodManager.1" key.
3.6 Now right-click and delete both of these keys.
I think that's all that's required, but I also searched through the registry and deleted the following keys.
4. Other keys I deleted:
4.1 HKEYCLASSESROOT --> IPodManager.IPodManagerUI.1
4.2 HKEYLOCALMACHINE --> SOFTWARE --> Apple Computer Inc. --> iPod
I think that's all I deleted, but I'm not positive. I seached for instances of "ipod" using the Find... and Find Next functions under the Edit menu.
5. Exit out of the registry editor.
6. Re-install iTunes. I re-installed iTunes and reconnected the iPod, and everything worked.
I want to repeat that editing the registry can completely mess up your computer if you modify the wrong things, so only do this if you're comfortable, and be extremely careful.
Hopefully this helps!
Apple support people: assuming this works, please add it to your solutions page, and feel free to reimburse me for spending half of Christmas figuring this out.

I get an error message when trying to sign into the support community with another Apple id. On the pick a username screen I get "an account utilizing this address already exists...." despite trying a few usernames. Anyone know how I can resolve this?

I get an error message when trying to sign into the support community with another Apple id. On the <pick a username> screen I get "an account utilizing this address already exists.Only one account per email address is allowed on the Apple Support Communities" despite trying a few usernames. Anyone know how I can resolve this?

This problem has been driving me demented. The instructions that Ivan gives have partially worked for me. By following his link
"How to find out if you have multiple Apple IDs" I was able to identify that yes I did have two apple accounts using the same e mail address. One was very old that I used to use for the forum boards and one is my much more recent ID that I use for everything these days. So I changed the e mail address for the old account which is associated with these discussion boards and that's the account that I am now posting this from. However even though the two accounts now have different e mail addresses when I try to log onto the boards with my more recent main apple ID I still get all the same errors as described at the start of this thread by rodgers_j. And of course that's the one I want to use so that I only have one itunes account for everything.
So if anyone has any more hints I'd be very grateful.

There is a problem communicating with the printer.

I have a Lexmark Interpret S405. I am using a MBP laptop with WiFi, running 10.5.8. I have a cabled (non-wifi) Linsys router. I am using an Airport Express.
I was finally able to get the WiFi light on the Lexmark to be static green after reinstalling the Lexmark WiFi setup and reconfiguring my Airport settings so that both the computer and printer see each other.
In fact, I even updated the driver from Lexmark's Web site last night and I watched the WiFi light on the printer blink green indicating that the installation of the driver update was being communicated to the printer.
However, when I print, it opens the print window and says first "Looking for S300-S400", then it says "Printer is now online". Then after about 10 seconds, I get this error: "There is a problem communicating with the printer. Make sure the printer is powered on and connected to the computer. Delete or hold the job and try again."
I've exhausted Lexmark's technical databases and couldn't find the answer here.
I've read that one possible solution was to delete all the printers from the "Print & Fax" system preferences window and re-add. That didn't work.
Lexmark says for: The printer communicating on a network; however, the printer is not responsive. Possible causes could be:
1. Your printer is associated with a network, router, or access point, but it is not your network.
2. A software process is blocked by a system security firewall preventing network communication.
3. You are logged into Virtual Private Network (VPN).
4. You are connected to a network but have decided to switch to a USB connection.
I don't have a VPN and have removed the USB cable, then restarted both printer and computer, and deleted printers in Sys Prefs, restarted, and still no solution.
I can print directly via USB cable, but want to print wirelessly.
Lexmark also says to enter my PIN (which I have pulled out from the print menu screen on the printer) in the System. That tells me a lot...
Network settings on the print window on the printer also tell me Signal strength is 5 (excellent) and that I am on the network my airport is on.
Message was edited by: Macman17

I bet this is too late but...
Are you trying to print through the airport express wirelessly or the built in wireless of the lexmark? If you want to use the airport express, there is no need to mess with the wireless printing on the lexmark at all. The airport express will be easy to set up, all the wireless setups through the printers are a pain.

ITunes Seem to Have Suddenly Stopped Communicating With the CD/DVD Burner

Hello, I wonder if anybody can help - my itunes application seems to have suddenly stopped communicating with my laptop's cd/dvd burner
(Generic Name (E: H - T-S D D A S - 20N ATA Device)).
About 2 years ago, I have experienced a similar problem, but was able to resolve it by downloading 64-bit compatible GEAR drivers to my system. However, the problem has re-appeared when I have updated to iTunes Version 10.1. Funny enough, the cd/dvd burner started getting recognized again when I updated to iTunes Version 10.2, but halfway through me burning a large playlist to multiple cds has suddenly stopped recognizing the cd/dvd burner again, and has never "resolved itself" ever since.
I have tried multiple approaches to solving this issue, including completely re-installing itunes software and completely re-installing GEAR drivers, but nothing works. I have even tried uninstalling GEAR drivers completely, as I read that it worked for someone on one of the similar forums, but that didn't work either.
My itunes diagnostics runs all the points of the cd/dvd drive check successfully, except for the last point (Can Not Read Audio CD). Here's what the diagnostics summary looks like:

I have noticed that the diagnostics summary containes a suggestion to update firmware of my laptop's cd/dvd drive, but currently there are no such firmware updates available.
Another frustrating issue that I ran into was trying to convey this issue to Apple Technical Support via e-mail using the Express Lane for the troubleshooting issues. I really fail to understand why I am being asked for the "hardware serial number" when I'm clearly choosing the categories for "iTunes/CD-DVD Import Issues" which are software, not hardware, categories! This prevents me from being able to simply send the description of my problem to the correct Apple Support department, and does not let me do that even when I enter my itunes' Serial Number, which can be found in the diagnostics summary provided above.
Much Thanks to anyone who can provide any kind of helpful advice, even if it's just on how to be able to convey this problem to Apple Support via e-mail!

Okay ... checking something else:
Current user is not an administrator
Is that true? Or do you in fact have a Windows user account with full administrative rights?
(It's possible that a permission may have gone astray in your usual user account, which might be causing the burning issues.)

SOLUTION to "Software required for communicating with the iPod is not insta

Folks, I can not take credit for this.....you should send your checks to MarkinMadison. I've included his post in it's entirety. For me, this was the Holy Grail !!
My only comment is make sure when you are in the registry that you hit the "apply" button to change and add things.
This probably won't solve everyone's problem but it clearly solved mine (and I tried all other "solutions"), as well as Mark's.
Apple: please find out who MarkinMadison is and either cut him a big check or offer him free Ipods for life.

Dimension 4600 Windows XP

I have also posted the same question, earlier today. I purchased two for my children and cannot get the iPod to communicate with the computer. I have the iTunes software on my system, but during the installation process I cannot click the NEXT button, once I plug the iPod cable in. The computer does not detect it. I have tried all 6 USB 2.0 ports. I even removed the Dell Jukebox and MusicMatch programs. I am not a computer savvy person - just a mom who wants to give these to my children for Christmas. This is the first "chat" site I have even registered on. I am so very frustrated. Hopefully, this can be resolved.

"An error occurred in the communication with the BW server"

Hi, when I open BEx Analyzer and try to connect to my BW server to run a query, I get this message, "An error occurred in the communication with the BW server".
Can someone help me.
thanks
Pat.

If it's happening consistently, it could be a problem with your local m/cs MS office and/or SAP GUI.
If it was working before:
1) Uninstall SAP GUI and MS office.
2) Install MS Office and SAP GUI...then try to connect to BW.
Good luck, BB

Error in communicating with DCR

Preliminary question:
     For LMS 3.2 on Windows, which is better 2003 or 2008?
Primary issue:
     Background: new install of LMS 3.2 on Windows 2008 sp2 Virtual Machine.
          Upgraded Campus to 5.2.1
          Upgraded RME to 4.3.1
          when updating device packages, services started extremely slow with anidbeng taking 2hrs. portal showed service unavailable.
          had to restart crmdmgtd to be able to login.
          most links in CS return the following:   Error in communicating with DCR server. DCR server may be down. Please start the DCR server           and then refresh the page.   The DCR server shows running normal.
          tried restarting crmdmgtd
          attached DCR.log
         tried CSCtd07131 .. no success

Windows 2008 offers more scalability so I would go with that although LMS has been tested on both (you will have a longer life of support as well).
When applying the CSCtd07131 patch, you need to be sure it is the right patch for the right CS version as there are multiple versions out there. However, this is fixed in LMS 3.2.1 so you should just upgrade there.
An often overlooked matter when installing LMS are the steps mentioned here:
https://supportforums.cisco.com/docs/DOC-9132
I see constant TAC cases due to installation problems because the above steps are not met or are half-met. Services starting slowly are usually an after-effect of something blocking ports (anti-virus or such) or possible database corruption. Setting DEP and anti-virus as specified above might help here, but if you did not follow these steps to the letter during this new install, I would suggest to cleanup this server and re-install properly; then move all the way to LMS 3.2.1.

Error in communicating with DCR server (Operations Manager 8.5)

Hi,
I just installed Operations Manager 8.5 on a new server. And, although I'm able to login to the OM, I'm unable to add any devices to the DCR. When attempting to add the device the following error is returned:
"Error in communicating with DCR Server
DCR Server may be down. Please start DCR server and then refresh the page. "
The same error is returned when an attempt is made toaccess the screen to change the mode (standalone/master/slave.) However, according to pdshow output DCRServer is up and running:
Process= DCRServer
State = Running normally
Pid    = 9220
RC     = 0
Signo = 0
Start = 7/29/2011 2:46:33 PM
Stop   = Not applicable
Core   = Not applicable
Info   = DCRServer is up and running
I've browsed the site and tried all suggestions for LMS since I didn't see any for OM. No success.
Any/all suggestions are much appreciated.
Kind regards,
Bart

It appears the answer is rather simple. According to a trusted source who works for a Cisco training partner, one must wait before even attempting a login into OM.
Apparently, it takes about 25 to 30 minutes for all the services to start. Any attempt to login to the OM may corrupt the database. This is based on CiscoWorks. When command "net stop crmdmgtd" is issued it takes about 5 minutes to stop the service and a confirmaiton that the service was stopped is displayed. However, when starting the service with "net start crmdmgtd" there is no confirmation that it started successfully. One may look into ":\ program Files\CSCOpx\objects\dmgt\ready" directory for a _lock file." As long as the lock file is present one shouldn't use the browser to login. However, I was advised the best approach is to restart the service and give it 30 minutes.
It worked for me
Kind regards,
Bart.

Error in communicating with Excel Calculation Services

When attempting to use Excel Web Access web part, I get "We're sorry. We ran into a problem completing your request. Please try that again in a few minutes."
Checked event log and found
There was an error in communicating with Excel Calculation Services
http://my server:32843/49082a5d56c141629497dd8b28375f47/ExcelService*.asmx exception: The remote server returned an error: (503) Server Unavailable.
[Session:
User: ].
I googled the error and, as suggested by various sources, rebooted the server. (Same issue occurs) I also tried disabling asp.net impersonation with no change. Ideas?

Hi ,
Reason for the error :
The Excel Services Application server computer is in a non-valid state and may need to be restarted.
Resolution : (Before taking the step toward to restart the server, try the below option)
Restart your excel service application app pool/ restart the excel service. (Reference :http://technet.microsoft.com/en-us/library/ee513104(v=office.14).aspx)
If you have more than one application server in the farm , then try start the excel serviceto a different server.
