Receiving UDP does not receive messages

Hello. I have problem with UDP receiver.

I can receive messages from the same port you write.

Stream: open vi--> vi--> read vi UDP UDP writing.  Transmitter and receiver usinf th test port.

When I try to use vi UDP listen port to just read, I get all the data.

Program flow. I use vi to send the command on the serial port to MCU. Answer MCU return by sending data to the network port using UDP.

I start vi to listen to a port UDP (see attached), then I sent the order to MCU. I can see the response on Wireshark, but UDP vi does not receive anything.

I checked the IP address. Lokks all the same. IP address of the PC and decice is the same as when I write and read at the same time. Any other port.

Any help please.

Is the port that you want to use to open? For safety that many IT services will be blocked in ports that don't think they are necessary, or don't want to use.

  • Microsoft Outlook express Outbox does not transmit messages - Messages remain in the Outbox for ever

    When you create new messages, outlook does not transmit messages. They remain in the Outbox for ever

    Assuming that you have checked The Send Messages immediately and you get no error message, you may need to the corruption of dbx files.

    Spend most of your messages out of the Inbox and then create new folders to send and sent items box after having moved the messages you want to save to a local folder that you create.

    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.

    In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.

    With OE closed, find the DBX files for the items in the Outbox and sent and delete them.  New ones will be created automatically when you open OE.

    After you're done, followed by compacting your folders manually while working * off * and do it often.

    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.

    General precautions for Outlook Express:

    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

    Not sure if you are still having the error message isn't valid win32.applicaiton.

    Get the error: not a valid 32-bit application can have several origins:
    I have listed some of them below.

    The file is corrupted, bad or missing.
    -If the hard disk is damaged or hurt it cause work programs to fail, either because not all data can be read from the hard drive the program is damaged on the drive. Run scandisk and defrag on the hard disk to check for potential errors.
    -If you run the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer, you can get this error.

    File is not designed for your version of Windows:
    -If you try to run a program that is not designed for your version of Windows, you can get this error.
    -Although many old programs designed to work in older versions of Windows will work with new versions of Windows, unfortunately, not all programs will not work.
    -If the program is an MS-DOS program more former start program or Windows, you can get this error.
    -If the program is designed for a 64-bit version of Windows and you are running in a 32-bit version of Windows, it will not work and generate this error.

    File is a virus, worm or other malicious program file.
    -
    This error can be generated by a file that is a virus, worm, Trojan horse or other type of malware file. Often, this will result because the antivirus installed on the computer will not allow the file to install or run. Try to analyze the file to check, it is not a virus or infected.
    -If the file has been checked and is clean, it is always possible that the virus protection program or a another program installed on the computer is at the origin of questions during installation or execution of the program. Start the computer in Mode safe and try to run the program. start the computer in Mode safe will be that nothing is running in the background that could cause this problem.

    Hardware incompatibility.

    -If you get this error during the installation of a program, it is also possible that the CD-ROM drive or the drive that you are installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.
    -Download the latest drivers for your CD player or other of the manufacturer of the computer or the manufacturer of the equipment. (Microsoft does not pilot for other materials)

    After working with someone who had found that the search function was located to ctrl + T instead of ctrl + F, I would suggest that you install also the keyconfig extension so you can see what strikes it's supposed to be to aid. Maybe some overzealous location it has mapped to another key?

    However, I do not think that this would explain the menu editing > select > all the does not.

  • CTRL + Enter Does not post message on Basecamp

    CTRL + Enter sends a message in GMail and many apps to use as shortcut 'send '. Works for me on GMail.

    But on Basecamp.com, it does not work when you post a message on Basecamp. Works well on other browsers. When I contacted their support, they said that FF does not allow for customization of this shortcut.

    What can I do to get this working?

    As GMail and many other sites demonstrate, it is not true. We can't really do anything, though, as they need to implement support for this shortcut in their application. If possible, you should follow with their support and give examples of applications where it works.

  • Firefox does not (no message). Firefox used to uninstall (no message)

    Firefox does not start. The hourglass appears momentarily, then disappears followed by effect of its development. There is no error message. The Task Manager is never loaded Firefox.
    Then when I try to uninstall Firefox, when I click on Remove, new hourglass appears momentarily, then silently disappears. I am running Windows XP.

    A sound effect of boom? Are you sure that you try to start Firefox? I never heard of that happening. But let's try a few methods. Each will be separated by a horizontal line.

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that disables some settings and disables most Add-ons (extensions and themes).

    (If you are using an additional theme, place you in default theme.)

    If Firefox is open, you can restart in Mode without failure of Firefox in the Help menu by clicking on the restart with the disabled... modules menu item:

    If Firefox is not running, you can start Firefox in Mode safe mode as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    Once you get the pop-up, simply select "" boot mode safe. "

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. Please follow the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

  • Put in regular page of e-mail does not display message in the list messages

    Hello

    I've updated my MacBook Pro at El Capitan and my wife Airbook.

    We both use the classic layout in Mail.

    After the update my Mail shows the message in my message in the message list a list (as it always does) I use this option so I don't have to double-click Mail and open it in a window separate to read.

    On Airbook my wife a message highlighted in the list does not appear in the list. (there is a small circle at the bottom of the list and hovering over him the cursor moves on the symbol to stretch or shrink the window, but it is just not there). She had it works just like mine before moving to El Capitan.

    This thread: Mail (El Capitan): display the preferences

    "says:

    Use Classic layout

    By default, messages are displayed next to the list of messages. To make messages appear below the list of messages (typical configuration), check the box. »

    I'm not sure what this explanation or if she's talking about my problem.
    I have no idea how to get the classic page layout to work the way it did before.
    Can someone help me get mail on the Airbook to redisplay the message highlighted in the list under the list?

    THX
    Brick

    Hello brick,

    Thank you for using communities of Apple Support.

    I see that your wife's Mac shows the display of the message during the classic presentation.  As you can see the small circle at the bottom of the screen, indicating that the screen has been pushed all the way down, eliminating the part look at a message.  Simply click, hold and drag the symbol upwards to bring this part of the Mail window.

    See you soon.

  • Mail vip list does not display messages from all mailboxes

    When I first put in place, I remember having the option to display the messages in all mailboxes - a really useful facility VIP. Recently, I noticed that most of my personalities was empty, but the messages were still there in their individual files. I followed the advice of aid to click Sort by Date, and then choose 'all the mailboxes' but this option does not appear. Moving messages of certain dignitaries other files back to Inbox makes it immediately visible in the Vips. So now, if I want my VIP lists for any use I leave everything in my Inbox, which is just chaotic and defeated the object to have folders for businesses, etc. It's only happened recently - it is connected to an upgrade or something similar, I wonder?

    Hi Boxmakermichael,

    Thank you for using communities Support from Apple! I'm sorry to hear that you're having these problems with mail. If you encounter problems with the function of VIP mailbox in Mail, you can find the information in the following articles useful:

    Address postal (El Capitan): search for messages from senders of VIP

    Mail (El Capitan): Mailboxes clever use to organize messages

    By default, the built-in VIP mailbox only checks emails from VIP which are currently in the Inbox, not in other boxes to letters or records either locally on the server. If you have e-mail set up a rule to move emails from specific VIPs in their own folders (or are moving them manually), it is probably why you don't see them in the VIP mailbox and why they reappear when you your choice in the Inbox.

    See the 'All the mailboxes' option "Sort by Date", you must select the individual mailbox the VIP under "VIP".  If your VIP example is 'Joe', select the 'Joe' mailbox then you will see the option "all the mailboxes.

    If you don't want not organized these emails in separate folders and view them all in a folder of VIP, however, there is a fairly simple solution. As mentioned in the article above, the integrated VIP mailbox is simply a mailbox smart who is set to pick up the mail of VIPs in your Inbox. While you can't change the settings of this particular mailbox, you can create a new box smart letters (called, for example, 'VIP'), where the only criteria is "Sender's VIP", without any limitation on the message tracking. This should then display all of your emails from senders of VIP, regardless of what box mailbox or a folder they are in. I hope it's useful and please let us know how it works.
