How to test if the pc is connected to the TCP/IP protocol?

Hello

I have a VI how should the data received from another PC, using a TCP/IP connection.

My VI could connect, receive data, but if I lose the connection im not able to reconnect, because I do not know how to test if my pc is connected to the other.

Thank you for your help,

Best regards

Hey,.

I was checking for error 66, I think that it check if the connection has been closed in order to reconnect

do you not think that the error 56 or 60 are better?

with respect,

56 is the time-out. This will depend on your remote service if this should be considered as error or ignored. If it is a server application, it should certainly be able to respond within the time limit. But if your host application is the server and the remote application is the client it is very common to receive a time-out error when querying the client if it has new data to send.

Order the examples mentioned previously, they really give you a good idea on how TCP/IP network communication must all work, even if there is still a lot to improve to create a truly reliable connection. But start from there come back if you get into trouble.

    Hello!

  • How can I activate the TCP/IPv4 properties button?

    Hello everyone, I am trying to solve a problem on my Windows 7 netbook. When I run ipconfig he returned only this line "IP Configuration of Windows" with later data. When I go to the wireless adapter and select Protocol Internet Version 4 (TCP/IPv4), the properties button is disabled. I unchecked the IPv6 checkbox. The wireless adapter is connected to the WiFi hotspot, but the status is not 'connected' for IPv4 and IPv6 connectivity connectivity. I already used the netsh command to reset the interfaces by this link ( http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/tcpipv4-properties-button-disabled/347899fa-b60a-40a3-ad2c-78ef5e0dca37 ). I also have the same problem with my Wired NETWORK card. Please can someone configure me this adapter to get a static IPv4 address or via DHCP?

    -Also reset the TCP/IP stack via (http://support.microsoft.com/kb/299357?wa=wsignin1.0#letmefixit )

    -Also tried re-installing the drivers (http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/the-tcp-ip-v4-protocol-for-the-built-in-wireless/a28c5096-d1c4-4cc4-ab56-236a163e3a96 )

    I had the same problem.

    I noticed that the button of properties available on the network security mode. So I started to disable suspicious services then I found the problem: his "Service to safety nut.

    Doing some research, I discovered that it comes with adware 'Movies Toolbar'. Even if you uninstall the "Toolbar Movies", "The safety nut" always running.

    To uninstall it just open services.msc, double click on 'Service of safety nut' and change the Startup Type to disable, and then restart Windows. When Windows are online again, the button of properties will be available and the safety nut will no longer appear on the services.

    It will be useful.

  • How to access a server based on the TCP/IP protocol port?

    Hi all

    Is it possible to access a server through a specific port via TCP/IP?

    We have a step of database server in our network that supports the TCP/IP access. My boss asks if it is possible to get some simple data via blackberry?

    The thing is that blackberry device is not in the network, how can we put a bb device in our intranet? Via enterprise server?

    Alternatively, if we can put the server on the internet, can the blackberry device access via TCP/IP?

    Thank you

    Jerry

    If you use wifi BB can access local servers. using direct tcp: nope.

    You can use a bes express (which is free) If you're afraid of costs, still takes time to install/configure etc of course, otherwise you can only use your product if your BB is in the local WiFi network.

  • How to test if the thermocouple is attached.

    Hello, I use the cRIO-9023 and the module NI9213 to read the temperature of the thermocouple. I give to the user up to 16 thermometers already programmed in labview to display the temperature. The question I have, is I want to disable the thermomiters if no thermocouple is connected. I called NOR and they said there is no function integrated to test it, so I have to check by comparing the value. for example, if the units are set to fahrenheit, so if a thermocouple is not plugged it reads to the as 2500 degrees, so what I want to do is to check if the type is fahrenheit and if this is the case, then my temperature max value 2000 degrees. Then I can test IF temp? 2000, disable thermomiter.

    How can I editor a programming like this statement:

    If Type = Fahrenheit THEN maxTemp = 2000

    ELSE IF Type = Celsius THEN maxTemp = 1500

    Basically I want a boolian to trigger an action to establish an indicator.

    Also, if I put an indicator of value of the dome, how can I read it by another controll?

    I would like a way to do it without globial/local variables as my cRIO dislikes the.

    Thank you!

    Use an appropriate comparison function. Most important in this case.

  • How can we change the TCP/IP ports used by LabView?

    I'm under LabView 8.2 on a computer running windows XP sp2.  This computer is connected to a compact RIO via Ethernet.  The system works very well, but now I am trying to add an IP intercom function (acoustic digital ii3) this intercom uses a program called talkMaster to communicate with the host computer.  I can't communicate with the intercom because this program needs of ports 3000,3002,5000 and 5006.   I used a program called Currports to see what ports are used, and a program called lkcitdl.exe (National Instruments Logos product name) uses port 5000.  Is there a way to change this? I contacted digital sound technical support and they said there is no way to change it at their end.

    Any help would be greatly appreciated!

    Thank you

    Jason

    I believe that we have an article on this somewhere, but I don't have a link at the moment. Under Windows, you can set the port range used by the protocols of Logos in the registry. Reach

    HKLM\Software\National Instruments\Logos\Ports

    You will find two values DWORD here, FirstClientPort, and FirstServerPort, which defaults to 5000 and 6000 respectively. Logos will search for the first available port in the range [FirstClientPort, FirstClientPort + 1000] or [FirstServerPort, FirstServerPort + 1000] when starts a server or a client. By adjusting the registry, you should be able to find a port range that does not conflict with your software. You need to restart all programs OR after you make this change (probably easier to simply restart the computer).

  • How to send files TDMS using the TCP/IP protocol

    Hello

    I work with the cRIO-9025, cRIO-9118 chassis and module NI 9239.

    I did an acquisition (voltage) where data are in 1 d Wfm SGL. I saved these data using a PDM file, but now I want to send this file to another computer (in this case mine) because the file is stored in the target. I have implemented this example:

    http://zone.NI.com/DevZone/CDA/EPD/p/ID/2842#0requirements

    The problem is that the tdms file is created but it has all the data. I have attached the image of the program. The program is in the other (not that I use to make Acq) to make it easy and then works when it works.

    * The file name of the client is not used because I had a conflict with the path.

    What I'm looking for, is to make an acquisition of 10 minutes every 30 minutes and then send this data to another computer (or other). I don't know if it's the best way, is perhaps better to send data at the same time as the acquisition is made, but my teacher told me that are easier if I send the file when acquiring ended. Acq, I use FPGA and RT.

     

    I would appreciate your help. Thank you!!


  • How can I disable the Windows XP Pro wifi connection?

How can I turn off the wireless? on Windows XP Pro. This tenth time im asking this question! Tell me there is at least someone other than my abuser! who knows the answer I needTHANKS * address email is removed from the privacy *

    Hello

    There are a number of ways...

    1. assuming that it is a laptop, there will be a physical to turn off wireless switch, or a depression function key. I can't say what function key, it will be, it varies from laptop to laptop, but the image on the key must be a gift, if the image is not obvious to you then check your manual. Use it with the "Fn" key as a "toggle switch" to turn on wireless power.

    2. go in network connections configuration panel. Right click on your wireless network connection, and then click on disable.

    Your PC is not necessarily to be attacked. It could just be set to automatically connect to networks unsecured wireless. There are a lot of unsecured wireless networks on, leastways in my neighborhood there. If your PC takes up and connects to one, it is not an attack in itself, but it could make your PC open to attack.

  • How to check if the lid switch is broken on Lenovo Thinkpad X230i?

    I have problems with my new Lenovo Thinkpad X230i lid switch and I would ask you how to test if the lid switch is physically broken. Since I bought the laptop a few weeks ago the laptop suspended when I closed the laptop, but still I had to press gently with my finger on the lid so that the laptop has recognized that the cover is actually closed. Now, this trick no longer works.

    Now, I would like to find a way to better test if the lid switch is physically not works. I found this article in the forum: http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X220-does-not-detect-lid-open-close/td-p/49626... and I followed the steps. I entered the BIOS and closed the cover, but on my laptop, the screen goes out, even if the cover is completely closed and even after pressing gently with your finger.

    I cannot conclude now that the switch of cover material is actually broken and I need the service of Lenovo?

    switch cover on the X 220 and X 230 is triggered by a magnet. The laptop enter the BIOS menu, then use a magnet and see if that turns off the display. IF this is your lid switch is working properly and the problem you are experiencing is most likely software. If it isn't then it is broken, and you need to replace.

  • How to test my application of ADF mobile browser on Android emulator?
