Help the analysis of UDP packets

• Regex help - the analysis of names

  I get the names of another system, and I need assistance, the analysis of the data that it is. There are errors of common input of the other system I want to correct that data are imported. I am formulating a regular expression to find and replace the common mistakes.
  
  Example 1: A folder with the family name "DE ROSA" is imported. Note that there are two spaces between "FROM" and "ROSA". I want to delete extra spaces. This one is more simple.
  
  Example 2: A file with the family name "DE ROSA - LA CRUZ" is imported. It's the same problem, but now there are two places where it should be fixed.
  
  Example 3: A folder with the name "LYNDE - ROSA" is imported. I would like to correct extra spaces in "DE ROSA", but not touch Lynde, which also contains 'FROM' at the end.
  
  I can't create a regular expression that finds all the scenarios that I need without including the results I want. These are the rules, I need:
  
  1. find the expression 'FROM' as a phrase with one or more spaces after him.
  2. the item preceding the "OF" must be nothing (the beginning of the line) or a character that is not a - z or A - Z.
  
  It sounds simple enough, but my expression either don't get "FROM" at the beginning of the string, or they catch the 'OF' at the end of a family name. The names are converted to uppercase simplified procession.
  
  Any help would be greatly appreciated. I tried to explain this with the simplest possible examples, but I can provide more information if it would help.

• Limits on the size of the UDP packets

  I can't receive packets UDP only larger than the size of 8192 bytes. I can receive packets that are lower (or equal) of 8192 bytes.

  Also if a 8193 bytes packet is sent from the server not only make time trying to receive (i/o operation has expired), but I can't receive all the smaller packages later. It's like this big package breaks any subsequent extraction. I keep time after him. I tried to increase the timeout, but it doesn't help.

  I was under the assumption that the limit of a UDP packet is 65507 (this is the output of datagramConnectionBase.getMaximumLength ()). Is there something that I am missing, or is this a limit?

  Here is a snippet of the code I use:

  private DatagramConnectionBase datagramConnectionBase;
  private Datagram udpDatagram = null;
  

  //Init UDP
  String url = "datagram://:" + getConnectionSuffix();
  datagramConnectionBase = (DatagramConnectionBase) Connector.open(url, Connector.READ_WRITE, true);
  
  //Send UDP
  String data = "HELLO UDP SERVER! [" + System.currentTimeMillis() + "]";
  byte[] buffer = data.getBytes();
  
  url = "datagram://" + txtHost.getText() + ":" + txtHostPort.getText() + getConnectionSuffix();
  udpDatagram = datagramConnectionBase.newDatagram(buffer, data.length(), url);
  datagramConnectionBase.send(udpDatagram);
  

  In a thread:

  datagramConnectionBase.setTimeout(1000);
  udpDatagram = datagramConnectionBase.newDatagram(datagramConnectionBase.getMaximumLength());
  
  datagramConnectionBase.receive(udpDatagram);
  byte[] b = udpDatagram.getData();
  
  logThis("Bytes: " + udpDatagram.getLength());
  

  Just to close this message. In the end, I never found any official or unofficial word on the maximum UDP packet size.

  The solution we have implemented was ventilation packets sent in 508 bytes and reassemble at destination. This seems to work great although it seems that there are times that the unit is being overwhelmed with packages it to drop some... but that's for another post.

• HP 4620: HP 4620 scans very well, but could not save the analysis in a file

  The scanner scans very well, but could not save the analysis in a file. Whenever I try to save, it crashes.

  Hey @motikama,

  Welcome to the Forums of HP Support!

  I see that you encounter some problems with the scanning of your Officejet 4620 e-all-in-one for your Windows 7 PC. I can help you with that.

  To start, make sure that the printer is plugged directly into a wall outlet, not a surge protector. Once done:

  1. Uninstall all software associated with the printer to your computer.
  2. Restart your PC.
  3. Download and install the latest drivers by clicking on this link.

  Please let me know the results after following the above. If you can scan, click on accept solution. If you appreciate my help, please click on the thumbs up icon. The two icons are below this post.

• The analysis of the non-numeric characters in a string

  Hello

  I am communicating a robot to LabVIEW (2013) via TCP/IP and sockets. The robot is the server, and LV is the customer.

  I start with the target data in this format (in a string):

  "[0 ~ 100 ~ 0] ~ [0.96593 ~-0.25882 ~ 0 ~ 0] ~ [1 ~ 0 ~ 0 ~ 0] ~ [150 ~ 50]."

  [X, Y, Z], [Q1, Q2, Q3, Q4], [C1, C4, C6, Cx], [TCPVel, OrientVel] except replacement ',' (comma) with a ' ~ ' (tilde) because I load the target data in a spreadsheet which is a comma-delimited file.

  In LV, I take this string, the analysis of the chain and split individual items. I then pulled the singular elements as unique, 32-bit of real numbers. I take each one and convert them individually to a string, concatenate them and send them to the robot. The robot decompresses these raw bytes individually and converts them to a target of robot (position in space).

  I train (BT) check if the user has sent a bad character (non-digital) in the target data. Example of this is:

  [- 50 ~-150 ~ 0] ~ [0.96593 ~-0 ] [B2has5D882 ~ 0 ~ 0] ~ [1 ~-1 ~ 0 ~ 0] ~ [150 ~ 50]

  Now in BT, when I'm scanning the chain, these bad character becomes the entire element to zero and everything else then to zero as well. See attachment for example screen similar.

  My question is, my VI, I can analyze all non-numeric characters (that are inside the parentheses and characters that are NOT a ' ~ ' (tilde))? In this way, I can always get this item numbers and do not have this element or other items turn to zero?

  Thanks in advance for any help!

  Sorry for the question of the test

• How to send UDP packets to multiple IP addresses

  I can see the full dissemination of forwarding UDP (IP value FFFFFFFF) but I do not see how to send the UDP packet even two or three specified multiple IP addresses.

  Is it still possible?

  Thank you

  Pawel says:

  The multicast would work with other receivers of udp (no-LabVIEW) operating in a mode normal unitcast? Or all networking needs receivers operate in multicast mode?

  Clients must join a multicast group in order for the multicast work. This essentially means that you tell the OS you want traffic received on a specific IP address (multicast groups are the IP addresses within a specific range) and on a specific network interface.

• What is the analysis

  I tried to uninstall some programs in the Panel, he said the analysis failed, what is the analysis

  and how fix this annoying problem, there are many games that have been removed from Office

  on it, should I uninstall in Control Panel as well. Thank you

  Hi tengarertermoana,

  Here are many sources that define the analysis - pick a bit until you understand: http://www.bing.com/search?q=Parsing+Error+Definition&FORM=QSRE1.

  But the real problem is that you deleted games from the desktop instead of deleting or uninstalling them and so the standard uninstall process is now having trouble functioning.

  In this case, I recommend you download Revo http://www.revouninstaller.com/revo_uninstaller_free_download.html (the free one for now), install and run it in advanced mode to uninstall and completely remove these programs from games.  It often works where standard uninstallation fails.

  If it turns out that some of the games do not appear in CP programs to uninstall and also not appear in Revo but you know they still exist on the system for some reason any - even though you did not mention that as a question (perhaps see it in Windows Explorer or in the registry (don't mess with the registry to change it here - just to see if you can find any evidence) , then the paid PRO version of Revo (with a try free 30 days you can cancel when done and then re-install the version free of charge as it is a great tool and I want to uninstall everything in advanced mode because it works better and keeps the System cleaner) has a partial ability to find remainders of programs that do not appear in the list. It's one of the reasons people pay for it - but I don't think that you need and not worth the money when the free version has almost always been around.

  I hope this helps.

  Good luck!

  Hi Billy,

  It's a problem of DC convergence in the simulation. In the scan options, select use custom settings.

  

  On the Global tab, the value of the Shunt resistance of analog nodes on the ground [RSHUNT] 1e + 008

  

  On the DC tab, set the iteration DC [ITL1] limit on 400

  

  Then simulate again and now you can see that they are all posted!

  

  

  Hope this helps!  :-)

If I click Cancel then I get error 1706, if I click OK, it just says: access to the content of the service... but nothing happens.

  Hi aubree737,

  I suggest that scan you SFC on the computer that will search the corrupted system files and check if it helps.

  The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows XP installation CD.

• HP Deskjet Ink Advantage 3545: Results of the analysis of the Palm of the hand

  I'm trying to analyze the Palm of the hand for the purposes of astrology. I'm scanning from laptop to the printer. When I use the color and grayscale options, the image just right with light background of my palm and dark and distinguished lines area. But when I use the black and white area light background most of Palm appears also in black. Fundamentally important field of my Palm appears black. But when scanning documents that does not happen. Y at - it another option to scan the Palm in black & white?

  Hi @F50,

  Welcome to the Forums of HP Support!

  I understand that you're looking to analyze the Palm of your hand for a class project and are curious why the black and white adjustment does not come out as well as scans of color and grayscale.

  I try to adjust the scan (PPP), superior quality and adjust brightness settings upwards or downwards to see if that helps.

  I don't think that your scans will be as sharp and vibrant because of the light entering the gap between the scanner cover. When the light seeps into the scanner, it can greatly reduce the quality of the scanned items.

  NOTE: The scanner in this printer is designed for scanning flat objects, not 3D images what is your hand.

  I would take a different approach to this. I suggest that you take a picture of your hand on a black and white camera or save to your computer and convert as black and white in the photo editing software.

  If you don't have a camera try this.

  • Darken the room as much as you can so that no light can enter into the analysis.
  • Place your Palm flat on the glass completely.
  • If you can't darken the room, temporarily put a towel or blanket over the scanner during the scan of the hand. Do not leave it on top of the printer. This is to try to eliminate all eternal light that seeps into the scanner.

  I hope this helps. Good luck!

• Drive CD/DVD not visible in BIOS, Device Manager or Windows Explorer - only during the analysis of the system.

  Until a few days ago, this problem didn't exist - I know.  My CD/DVD drive is no longer recognized in Windows Explorer, BIOS or Device Manager.  It doesn't, however, appears briefly in Windows Explorer in the analysis of the security of the computer.  It allows to open/close, etc.  and when it is visible, I am able to open the drive and see the contents of the CD.  Then it disappears again.  The light flashes indicating that he works and I can hear it trying to read the CD.  I uninstalled iTunes because I read somewhere that this may have been the issue - but that didn't work.  I tried the system restore, registry cleaners, removal of upper/lower case filters from the registry, used the program Fixit found on the site Web of Microsofts etc and still no luck.  Any ideas?  The computer is a gateway SX2850 (?) with Windows 7 Home Premium installed.

  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
