  • Adobe AIR - Inconsistencies in detecting whether Adobe AIR runtime is installed

    Hello Flex community,
    I am having issues with detecting whether Adobe AIR is installed  using the following process: http://livedocs.adobe.com/flex/3/html/help.html?content=distributing_apps_3.html
    Having installed Adobe AIR 1.5, we are at times getting a value of  not installed from the getStatus() function of the air.swf located at  http://airdownload.adobe.com/air/browserapi/air.swf
    Has anyone else faced this issue before? If so, does anyone have any  steps to resolve it?
    Thanks!
    Mauricio

    After doing some more research on the issue, I have found other users encountering the same issue we are:
    http://groups.google.com/group/air-tight/browse_thread/thread/706716c29caf0254
    http://www.flexdeveloper.eu/forums/adobe-air/air-swf%27s-getstatus-method-mistakenly-retur ns-%27available%27-when-air-is-installed/
    http://forums.adobe.com/thread/435935
    In the second thread, it says:
    “My issue seems to be specifically related to the use of "Silent Install". My client has a distribution license for the AIR runtime and is bundling the AIR installer with their installer. When Silent Install is used to install the AIR Runtime, Adobe's air.swf reports that the runtime is not installed. This happens until the user initiates an air app, at which point air.swf is able to detect the runtime installation.””
    This seems to suggest there is a bug with the Silent Installer or with the air.swf getStatus function. I tried the steps above and was able to recreated and resolve the issue. Does anyone else know of a different workaround?

  • Is there a way for Flex to detect whether the Java Plug-In is installed?

    Hi All,
    Need your help.
    Is there a way for Flex to detect whether the Java Plug-In is
    installed? This may be require a JavaScript External-Interface. Can
    we get if the Java Plug-In is installed and if so, whether it is
    JRE 1.6.X ?
    Regards,
    Amit

    Not knowing what server your app will run on... but something
    like that can be done relatively easy serverside with for instance
    ImageMagick if you run PHP.
    Otherwise, look into Bitmap programming.

  • How Can I Detect Whether the User's Firefox Supports MHTML?

    Is there a browser capability property that I could look at to detect whether the user's version of Firefox (including, for instance, an "unMHT" add-on) supports MHTML? Currently we provide reports to our users in this format and want to provide a link to add-on's in case the user cannot actually view the format; but show the report if the add-on or capability is present.

    Sorry, you can't detect if a user has unMHT installed.
    Have you tested your MHTML files with Firefox and unMHT? <br />
    MHTML was never adopted as an official standard by W3C - http://en.wikipedia.org/wiki/MHTML - and from my limited usage of unMHT, it isn't exactly the same as what MS uses with IE. I have had problems displaying a file saved in one browser in another brand browser, and don't remember the specifics beyond IE8 won't correctly display unMHT files even when the file extension is changed from MHT to MHTML. Plus there's a 2nd add-on / extension - Mozilla Archive Format - that some users may have installed for MHTML files.

  • Initiate a dial-up connection or detect whether I am connected to the net

    I want to initiate a dial-up connection from my java program and also to detect whether I am connected to the internet or not.

    well I am developing a proxy server and I want to add
    a feature of dial-up demand that detects the current
    connection status and if not connected to the net then
    call the dial-up dialers in dial-up networking folder
    and then connects to the internetI'd say it works like I wrote earlier:
    Keep yourself in the proxy-server the connections-status.
    If your proxy-server runs on a normal PC, it should be enough to try to connect to the internet.
    But do you need control over multiple dial-up dialers etc., this probably isn't enough.
    If I can find the time, I'll look into it.
    Maybe direct access to the modem is also an option.
    That depends on the modem of course and then you probably also need additional scripting. I guess that's not what you're looking for, but if you need info on that, it's probably also an option to look at a wvdial-script on Linux for connection to the internet. It might also be a problem if you have multiple channels for connecting onto the internet (cable,phone,ASDL etc.)

    Load the drivers and you should then be able to add it in Print Center.

  • How do I detect whether a publishing object is connected to the datasocket server or not?

    I have 2 vis which communicate via datasocket. The behaviour of the second vi depends on whether the first vi is running or not, and both vis can be started and stopped independently of each other. I need vi 2 to be able to detect whether vi 1 is running or not. Simple, I thought, I'll have a boolean in vi 1 called Running which is set to True when the vi is running and False when it shuts down. I'll publish that vi to datasocket and have a matching boolean in vi 2 which subscribes to it.
    It doesn't work, because as soon as vi 1 stops, Running disconnects and the matching boolean in vi 2 misses the fact that it got set to False before it disconnected, and just gets stuck in the True state.
    So it seems to me there should be a "Is object connected?" vi or function somewhere, but I can't find it.
    Is there another way to detect whether a vi is running or not? Preferably without using shared globals as I find that quite ugly, in fact I've switched to using datasocket from using shared globals because the latter just seemed like really ugly programming.
    Note: I will have several variants of vi 1 with different names, so I can't just try to open a reference to the vi. That's why I wanted to use a datasocket object; all the versions of vi 1 can have a boolean called Running.

    I found a solution. The subscribing boolean in vi 2 is now in its own little loop that executes every 50ms in parallel to the main program loop.
    In vi 1 there is a delay of 500ms between the publishing boolean being set to false and the vi stopping.
    That way the subscriber boolean has plenty of opportunity to read the False state of the publisher.

  • How do i know if an add on was installed ok

    I am increcidibly lame when it comes to computer talk. I just installed Firefox and installed the add-on Addblock plus. How do I know that the add on was installed? Is there somewhere that I need to enable the add on also?

    You appear to be using an outdated unsupported version of firefox. (From looking at the system details aside). You possibly will be unable to update from Firefox 5 to Firefox 7 using the Help menu.
    Download the latest version from an official website such as:
    * http://www.mozilla.org/en-US/products/download.html
    * take CARE '''not''' to use any options saying something along the lines of'' remove personal settings'', because that is likely to remove profiles from all normally installed versions of Firefox, and you will loose data such as settings, passwords and bookmarks.

    what are the steps in deleting in add remove to install a clean version of itunes/quicktime?
    What has to go, in order, like itunes-quicktime-mobile me, or?

    There are two part when installing WebEnt.. The first one is the web server part where it installs the fortecgi.exe or other web server components. This should be installed where the web server is going to be running. This is usually not you development server. The second part is the http library and web designer part. This should be installed on the development server. The http library need to go through a install of its own to make it part of the central environment. After that all the developers will have access to the http library and all they will need to do is install the Web desinger part.
    Hope this helps.

  • Is it safe to use DISM /add-package to install updates on online Windows image?

    Is it safe to use DISM /add-package to install updates on an online Windows image?
    I mean what happened if you run the command on a folder which contains an update and another update which deprecates the another one?
    And what will happened if you have installed an update and try to install an update which is deprecated by that update using DISM?

    If you are wanting to install a Windows Update .msu file, use WUSA.EXE instead:
    c:\windows\system32\wusa.exe c:\temp\Windows6.1-KB2505438-x86.msu /quiet /norestart

  • Add-ons getting installed when i have add-ons update unchecked

    In the Options-Advanced-Update I have Add-on UN-Checked to not install add-ons.
    The last few times I've started Firefox, the Add-on window appears to inform me that new add-ons were installed.
    Why is this happening when I have this option turned off ?

    That preference is for addon '''updates''', not for unrequested installation of addons or addons you choose to install.
    Exactly which addons have been installed that you didn't specifically install yourself?
