Interact with a CGI web page

Greetings OR Forums,

I am developing a telescope pointing control system that needs data ephemerides generated from a Jet Propulsion Laboratory web site:

http://SSD.jpl.NASA.gov/horizons.cgi

The main interface of their horizons system is via Telnet which is precarious and is no longer supported by LabVIEW.  I was hoping that someone could advise me on how to start using LabVIEW to interact with the web page of cgi based at the above address.  If I can do it, I can retrieve the necessary ephemeris data and analyze inside LabVIEW using the commands of the base string.

Is there a kit of basic tools that you can point me to interact with web pages or any code sample?

Thank you

Use screws of HTTP Client:

VI GET is the standard demand 'give me this web page' - give it the URL of your ephemeris data session and the release of 'body' will give you the web page content - if you use the raw text of output, then this should make analysis easier chain (without tags html etc..).

(In addition, you can use Telnet in LabVIEW, it is not a library group for her more - you should be able to use the TCP screws to roll and you can also if interface with other libraries/applications Telnet for example PuTTy... it might even be something in .NET)

I used the restoration of the system for the two issues, and it does not correct. I was able to have sound and enter pogo until the other day. a counsellor please help!

    Hi palmershomedecor,

    1. Did you the latest changes on the computer?
    2. What version of Internet explore that you use on the computer?
    3. Facing the sound issue on all Web sites?
    4. You have security software installed on the computer?

    Method 1

    I suggest that you reset the default settings and check if you get sound on the Internet websites explore.

    For more information, see the article.

    How to reset Internet Explorer settings

    http://support.Microsoft.com/kb/923737

    Important: Reset Internet explore its default configuration. This step will disable also any add-ons, plug-ins or toolbars that are installed. Although this solution is fast, it also means that, if you want to use one of these modules in the future, they must be reinstalled.

    Method 2

    If the previous step fails, then I suggest that you uninstall using Device Manager and later reinstall the latest audio drivers on the computer by visiting the computer manufacturer or the manufacturer of the sound card, check if it helps.

  • Trouble sometimes with WebView short Web page rendering

    I noticed sometimes in my application poorly rendered Web pages in a WebView because the webview appears dynamically size itself so that it is only as high as it should be... so if something to Center vertically, it appears at the top of the screen, not the vertical middle of the screen. There was even a Yahoo/Facebook login page that started small and has started to grow a few pixels per second!

    I tried to add:

    verticalAlignment: VerticalAlignment.Fill

    ... for the WebView to the ScrollView as if it is contained in and to the container that contains the ScrollView, but that doesn't seem to help.

    I found another post on the forum that answers this question:

    WebView {
        ...
        preferredWidth: Infinity
        preferredHeight: Infinity
    }

  • Error with Conversion Util Web Page: "not able to access installation of Acrobat Capture Web. Acrobat may be busy or waiting for input. »

    Hello

    I get the following error message when you use the Page convert to PDF module in Internet Explorer: "not able to access installation of Acrobat Capture Web. Acrobat may be busy or waiting for input. ».

    I use Acrobat X (with latest updates) on Windows 8.1, 64-bit and IE 11 (both with all latest updates).

    When I click on the button to convert the top of IE, I'm asked to select the file location and name.  When I click on save, I'm presented with this error.  The utility creates a file, but it is unreadable - opening it gives an error in Acrobat, saying that the file is not a supported file type and it was damaged.

    I have seen this error in the forum and took the advice given to run the repair via Add/Remove programs.  I have run the repair and restarted twice, but to no avail.

    I also uninstalled, rebooted and reinstalled, but again, no luck.

    Please let me know what to try next.

    Thank you

    Hi Jody,.

    Please post on the Adobe forums.

  • Interaction of portlet and web page

    Hello

    The scenario is that I need Portal weblogic integration with a content server.

    (Action required: users need to download a file from a static page to the content server)

    So I used CPS (content portlet suite), which I was able to do it successfully.

    I can check a file by using the small window of portlets. I have also included a portlet login.portlet for logging xtra in weblogic portal of a white paper.

    Now, how do I download a file directly to content of some fields in data meta pre determined and front end server user article met portlet window. I want to say that the static page of front end will only Browse tab, then on the button send/Upload.

    No idea how should I continue straight. Also a new user of the portal (it may be you) will have no user id / password, so how to connect can be managed for the verification of a document in a content server.

    Thank you in advance.
    Dmenard

    CPS stands for Content Portlet Suite, CIS is Content Integration Suite. In my view, the CPS is inspired by CIS. CPS is a set of portlets that can be run in a portal environment (JSR168), while CIS or RIDC are methods of integration based on Java - it helps if you're an experienced Java programmer. Basically, you need to write your own application that calls the functions of the Complutense University of MADRID. CRMI is said to be lighter, but CIS has more functions (you should be able to do almost everything with CIS what UCM is capable).

    If you are not experienced in Java, but you know other programming languages, you can integrate with UCM also via web service calls.

  • Problems with the initial web page et al.

    Hello

    I just downloaded Foglight and created a virtual machine from the file .ova.

    Logging on to the server Foglight has worked since the console - I need to manually change the IP address.

    I ping the Foglight Server from a computer on a different subnet.

    Following the instructions I can connect with a web browser.

    This fails as if the server is not active.

    Port 80 seems to be open, but tomcat is running.  Netstat - ano says tomcat has no open ports.

    On a likely related note, when I try to use putty (ssh) to the VM guest, I am challenged for a password, and

    Enter by default of the doc to install, but it does not work with access denied.

    When I use ssh from a Linux box on the subnet, it records the machine, then abandon the connection.  The following connections for this host fail with a "man in the middle" warning.

    Ideas?

    Thank you-

    Rob

    Hi Rob,

    When you have changed the IP address, you use the /usr/local/vkernel/scripts/changeIp.sh script?  If you tried to manually set using other methods, Tomcat configuration files will not be updated, and if the web server will not respond.

    The login/password for SSH usage is vkernel/vkernel.  Some people type it as 'vkernal' but it's 'vkernel.  Does not root via SSH.  You will need to "known" to the root once you have logged in as vkernel.

  • My gif files are not displayed on the web page

    My web page has some gif images that are not loading

    Your own solution, you probably need to do is clear cache more often. Especially if you work with your own Web pages. As well as the update of your site if it matches what is on your computer.

    To refresh a page using "F5" to refresh without cache but use 'Ctrl + F5 '.

  • Question about windows theme and display of Web pages

    I have everything, I'm new here, I've had my laptop for about 8 months, but it was stored for the 6 months, so he had only 3 months of use, and that was 99% for watching movies as was my laptop backup (my girlfriends, which was never used)...
    Well I just got my laptop storage and started using it again as I want now to do that my main work computer, it's a Satellite A100 Series. Running Win XP Pro SP2. Well, now I used it for about 1 week now and this is a fantastic computer, expecially the swipe away feature, I'm usually one XP Home Edition, but I do with Pro, just did not have any experience with it...

    Now, here's the problem, and this has always been the problem since bought, when we first bought it and connected to the internet with IE7 fonts have been massive, I figured out how to fix this in the display after a few hours to play settings and also noticed Web pages if there is a background image, it does not appear... (I also found this week is the same for any application on the PC that uses a Web page as Set up, or something, just sectain things... as I open the Security Center in the control panel and everything is white, and background images aren't there (which is white) and even corners which are background pictures are not displayed and comparing to) my other computer, there should be a green and red, background color etc.
    With Windows Media Player buttons should be as purple and black in WMP11, and they like a white background style html on buttons with links to them at the top and playback, stop, etc buttons have a back outside and the inside is white...

    Basically what I'm saying, is that she appears not CSS style WC3 content on some pages and applications on the laptop, and with regard to Web pages that they are exactly the same, I tried IE7, FireFox, front Browser, and still, the only one that displays pages almost as it should is Opera 9.2, but I really need to solve this problem... it is something simple to do with display obioussly , or settings, but I have tried literally every single different way of doing things last week, tried everything in the Control Panel, all toools Toshiba and no results.

    I'm not a beginner, or whatever it is, I can't get this problem, I can't even think of a setting that would do this let alone in trying to resolve this... I have all the Windows updates (although as I said, he did this from the first day of purchase)...

    If I could post a screenhot here I could show you... what Web pages look like in IE7 and FireFox and before (the only difference is Internet Explorer pages is mostly gray and firefox is white, gray is also.)

    Another question, when I was messing with the settings in the Control Panel, under Performace I changed it to something like 'make optimal display for performace' rather than 'Best to display' and it is then my control panel simple with a white background, and everything is not how I'm used, even the categories are made for each section , they are just all grouped together here, and my house Windows on my other laptop is positioned like this, but it at least has a sidebar on the left with a button to change it back...
    now I am at a loss to find the Performace button, as it is there is more, and I want to change it to 'show better for display' not the persomance... so if someone knows how to do this, please let me know... I took a screenshot of my control panel... and it's not naked, I use the Zune Windows (the black buttons and backgrounds theme ), so he used to be a gray background with a status bar on the side with all the links and details dark just like folders etc... So yes, it is another thing that I want to fix.

    Also I do not have the CD to fix it, not more that I think that she needs, but I have a standard out of the box disk Win Xp Pro, I was seriusosly do a fresh install, but I know I'll lose all modules of toshiba and all the extras that it is came up with, that's the only reason for which I don't have as it has Protector Suite QL, that I would have to pay to settle down to do a cleanup, and I really want to do because there is obviously something missing, its as simple as that, there is nothing wrong with the system it is just not set up correctly.

    Here are some screenshots of how I see Web pages, my Security Center Page and my control panel because I messed up he do "Get the best performace of" upward and the screen turned to the basic white and half things in the control panel is now missing, it has been setup in the previous categories... ahhhhh When I try to solve the original problem, I've done another...

    http://i203.Photobucket.com/albums/aa134/phorumws/just%20stuff/ScreenHunter_01-1.jpg

    {It is the Security Center screen when I click in the Panel, that was before I did it fade)

    http://i203.Photobucket.com/albums/aa134/phorumws/just%20stuff/ScreenHunter_02Sep3021.54.jpg

    ("it's now my control panel once I went in ' Premformance and display ' (I think. it was certainly performace in the name of the category)... and I changed a parameter of performance and display which actually use less resources... now I can't change it back, as the button performace is no more :())

    Thanks for reading and I hope although there, can anyone help me cos I hate having to do a fresh install on something as small as this, it is not many programs Add on on my laptop, as I said, it has probably beeen used 20 times ever, and especially for watching movies up to 1 week where it sat in storage for 6 months ago ,,

    Any help would be greatly appreciated... I tried all the Options of the Internet, all the Display Options, all variants, I need something specific, it is not only perform the internet, but the global programs with html style links, etc. and certainly CSS style sheets and the background image in the HTML feature.

    Thanks in advance.

    Hi Jay

    Very impressive display! I can see after 4 days, nobody wrote anything to give you the solution for your problem. I read your announcement with a lot of attention and I have to say that it was not easy to figure out your problem exactly (perhaps because English is not my native language).

    I know very well that new OS install is radical and last solution but I recommend you to check some forums Microsoft WXP because issue described is, in my opinion, more for OS forums for Toshiba forum.

    If you display the same thing in forum Microsoft please post the link, and we can follow the discussion here.

    I wish you good luck and I hope you will find answers soon.

  • Problem with the WIndows Update page

    I am running Windows XP with Service pack 3. Microsoft Security essentials is the security system. When trying to run Windows Update using Internet Explorer 8, at the point of the page is to check that if my system is the correct update software, the page fails, finally displaying the message "Internet Explorer has stopped to try to restore this Web site. It seems that the Web site continues to be a problem. "This is repeated each time I have repeat the initial attempt, or click 'Back to the microsoft.com site' on the error page. Is the problem with the Microsoft web page (the address is www.update.microsoft.com/microsoftupdate/v6/default.aspx ) or on my computer?

    When I try to run Windows Update... to the point that the page is to check If my system is correct, update software the page can't...  Is the problem with the web page of Microsoft ( www.update.microsoft.com/microsoftupdate/v6/default.aspx ) or on my computer?

    You are correct George: whenever you access the site Windows or Microsoft Update, Windows Update will take care of updating itself. that is, it looks for updates available from the Windows Update Agent or the customer allows you to update your system.

    Since June 21, 2012 a WUA new version 7. 6. 7600. 256 aired by WU to automatically update itself its version now aged 7. 4. 7600. 226 .

    The problem you see may occur when there is a version mismatch of the file with the Windows Update Agent files, which is a mixture of old files with the new files. This is due to an installation "or damaged."

    You can take a look at your windowsupdate.log file located in your WINDOWS directory, to check the error codes - missing files or failling updated files (especially c:\windows\system32\wuapi.dll, wups2.dll, c:\windows\system32\wups.dll or wuweb.dll).

    You must re-register or re - install files WU in order to obtain the Service Windows Update works again. Try here:

    What worked for me was to adjust IE from within IE using the drop-down menu of the Page then Zoom and the size of the text until I had him where I wanted.  Then I closed it and all of the following openings open like this was closed (which is now the default behavior).

    I hope it works for you.
