Wherefore art thou Control of Picture? 2D or not 2D?

The little VI utility made the jump from LabVIEW 711 to 2012 today. It was useful in the following way. The 'picture' was a large .png, let's say 3000 x 1500 pixels. The picture control was about the size of 500 x 500 but it had scroll bars, so it acted like a magnifying glass for the picture. The picture control returned the mouse coordinate values in terms of the large picture, so for example if I slid the scroll bar and moused onto a different part of the picture I would get the mouse coordinates of the picture (and not of the picture control widget.)
The 2D picture control will show the big picture, with the scroll bars, but the mouse coordinates are always the position of the mouse in the widget, not the postition of the mouse in the picture. So this bug has broken my program because it is using 2D picture instead of picture control.
Another observation is that a direct conversion from 711 to 2012 yields a block diagram picture VI from the library with a big-fat-red-X on the icon. Does big-fat-red-X on library icon mean anything? Do I have to baby along  these red-X VIs to get my new stuff to work? It seems that some direct conversions with red-X VIs still sort of work.

Maybe it's just me (though probably not), but I'm having a really hard time following. How about instead of the clever banter and the assumption that we understand you, you simply describe exactly what you're seeing and what you're actually expecting to see, ideally with some code attached so that people don't have to guess.
I have several potential theories off the top of my head, but can't apply either one without actual understanding:
There was some change made to the picture control VIs. The only reason I know that is that when I back saved a VI which called them to an earlier version, LV said something specifically about that. I think it was between LV 7.1 and 8.0. I have no idea what the actual changes are. I certainly haven't seen a change in the API between 7.0 and 8.x and I know it fairly well.
LV 8.0 introduced panes which changed the way LV treats the position of controls on the front panel. I would expect that a program imported from an earlier version would work correctly (at least that has been my experience), but maybe you're doing something which broke it. Or your utility VIs needs to be adapted to work with this. I would say that's the most likely scenario.
You're using .NET (the "constructor" comment ) and something changed in the way LV talks to it.
As for the "2D picture", I haven't checked but I'm assuming that this is simply the picture control you're used to (makes sense, since you say you didn't change the code). If that's the case, the reason for the different name would be that after 7.1 LV had a 3D picture control added and NI probably renamed the picture control to 2D picture control to make the difference clear.
Try to take over the world!

  • Oh wherefore art thou ACTION

    Could some gentle soul please give me an example of using methodbinding (I think that's what I should be using now that action is no more)
    Despite some comments to the contrary there is woefully little to go on in the latest release as regards to fixing my previously working code.
    I want to know how to call my 'action' code.
    Do I still have an action reference in my submit form?
    I so, what does it look like?
    Do I still have a property in my bean?
    If so, what do I do with it?
    If not, what do I do?
    I would like to say thanks to the JSF team for their hard work. I am sure I will understand just what they have done when someone describes it.

    I'm rarely described as a gentle soul, but I can help... You need only do two things: change "actionRef" to "action" with the new braces, and change your "return new Action()" code to just a simple method. So, for example...
    First, in your page, take:
      <h:command_button actionRef="foo.bar"/>.. and make it:
      <h:command_button action="#{foo.bar}"/>Now, in your code, take:
    public Action getMyAction()
       return new Action()
         public String invoke()
           return _myAction();
    private String _myAction()
       // code in here
    with the much simpler:
    public String myAction()
       // code in here
    }So, there's still an action reference in your page, but there isn't really a "property" in your bean - just a simple method, and that lousy inner class bites the dust.

    Quite so.  Don't know if it was related, but during this exercise the  printer stopped responding with a status "printer not connected".
    Restored tmpfs and printer.
    The real culprit in exhausting tmpfs was kaudiocreator which does have a default directory option.

  • Pages, oh pages, wherefore art thou?

    Hi guys. I recently upgraded computers to MBP i7 2.6ghz running 10.8.2 (as my old one died a terrible death) and I'm having no luck installing iWork '09 from a store bought disk from 12 months ago. The software installs, and I can upgrade from the app store..... however pages just will not run. I have plenty of space and ram, I've tried deleting and re-installing/upgrading several times, deleting the preferences file (only to be replaced automatically), even repairing the disk permissions. I am at a (slightly grumpy) loss.
    I cannot open a new document. The template chooser is just a black screen, followed closely by the spinning wheel of death. Keynotes and numbers just crash immediately apon opening.
    I really don't want to have to buy the software off the website again, mac has had enough of my hard earned lately, and I'm not sure if that would work anyhow.
    I'm getting a little frustrated as I need this software for invoicing etc.
    Any clues?
    Aaron.

    Yvan Koenig, a valuable contributor to the Pages community wrote an AppleScript that tracks down and removes every file installed by the IWorks '09 DVD or direct iWork '09 downloads from the App Store. People that have run his script and subsquently reinstalled iWork '09, or direct-downloaded from the App Store have reported normal functionality.
    You can obtain his AppleScript called, “uninstall iWork '09.zip from his Dropbox account. Once unzipped (double-click), there are two files: 1) The source, with the Applescript file extension, and 2) the executable AppleScript without the file extension. You may have to open the AppleScript source in the AppleScript editor and recompile it. Then double-click to run it. Should be no reason for you to know AppleScript.
    This is not a direct download link, but rather, a link to the folder containing the .zip file.
    Good luck.

  • LabVIEW PDA customize boolean control with picture

    For a PDA application, I'm looking for a way to customize a boolean indicator. To do this I went in the customize option of the boolean and then import picture for the false and true state. in programming mode I see the correct picture for the different states but when I download this application on my PDA (TPC-2006 with winCE) in only see a blank picture on the boolean. Is this a limitation of the LabVIEW PDA or is there another way to do this ?  (see example in attachement)
    Thanks in advance for your help.

    Hey Poussin,
    You bumped into a boundry of LabVIEW PDA. LabVIEW PDA did not support custom controls at all uptil very recently. Only since LV PDA 7.1 there are a few features which are possible like coloring and resizing, see the link below.
    http://digital.ni.com/public.nsf/websearch/08DD9CAACA1F64F586256E920061E4CD?OpenDocument
    Using pictures however is not possible. The control will have its functionality on the PDA but it will not show its decoration.

  • "the activex control for flash player could not be registered" - Solutions Roundup

    I recently ran into this problem on my computer:
    http://at32.s3.amazonaws.com/flash_install_problems2.jpg
    I am a Flash developer (as in I write SWFs, I don't work for Adobe).  and when I updated IE to 10.2, "the activex control for flash player could not be registered".  Since I am a developer, I also have Firefox and Chrome installed, with Flash running without problems.  For a long time now, Internet Explorer has used a different version (ActiveX) to the other browsers, which use plugins.  I am a strong supporter of Flash, it's great to develop with and has a very wide feature set which is growing all the time, unlike fixed technologies/standards.  However, the weakest part is the install process - I don't understand why their is a Download Manager.  Google Chrome does it's best (so far) by managing the install/update process entirely in the background.  Anyway, it was in my best interest to try and get to the bottom of this.
    For the record, on the problem machine I have Windows 7 with IE8, but I have seen almost  identical symptoms with IE9, Windows XP SP3, as well as various  iterations of Flash Player (10.0, 10.1, 10.2 and even some final  editions of version 9).
    First I tried the standard support here:
    http://kb2.adobe.com/cps/191/tn_19166.html
    Basically, doing the manual uninstall and manual install of the latest version (without using the download manager, or have IE open).  This did not work.  I also tried the Microsoft "subinacl" program, together with "reset_fp10.bat".  This didn't work either.  However, you should try all of these things first before progressing further.
    A quick note about people who had tried running the following at a command prompt: "secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose"
    I didn't do this, because on investigating further it didn't seem to work with Windows 7, only Windows XP, Windows 2000 or Windows 2003 - though there was a few threads where this had fixed the problem for some users.
    For my solution, it is recommended you use the manual uninstall / installers, so you should have them downloaded ready to use.
    I then heard about problems with permissions in the registry with the key: HKEY_LOCAL_MACHINE\Software\Classes\shockwaveflash.shockwave
    So I opened regedit.exe (start - run - typed "regedit.exe"), navigated to the key and sure enough, I couldn't open it - permission denied - even though I had an administrator account.  If for some reason, you can access this key (and any subkeys), then it's likely the following fix will not resolve the problem.
    I then done further diagnosis, by using Process Monitor to try and install Flash Player, and I got the following:
    http://at32.s3.amazonaws.com/flash_install_problems.gif
    This shows all the access denied errors the Flash Player install was experiencing when trying to write to the registry key.  This confirmed that this was the problem.  I only stress this because several people said it was unwise to tinker with the registry.  Though this is common advice, this is the only known fix for this precise problem at present, since you need to manually adjust the permissions yourself.  I don't know who is at fault here - Microsoft or Adobe - but let's just get Flash fixed...
    The solution:
    Firstly, you may want to backup your registry, or the exact key.  I didn't do this so I've provided no instructions on how to, but it is recommended for the paranoid.  Also make sure as much software is closed down as possible - browsers, IM software, any junk in your system tray. As way of example, I happened to have "BBC iPlayer" installed and running in the background which uses Adobe AIR and Flash Player, so I exited that too.
    1) Open regedit (start - run - type "regedit.exe").  You may need to right click on it and select "Run As Administrator", but I didn't as my account was already administrator.
    2) Navigate to the key. HKEY_LOCAL_MACHINE\Software\Classes\shockwaveflash.shockwave
    Click on it to confirm that you cannot access it (you will get an error) - if their are no problems - this probably isn't the cause of your issues.
    3) Right click on it and click Permissions, and ignore any message that may pop up.
    4) Under "Group or Usernames" click "Add".  Type your account name name, or "Administrators" in the box, then "Check Names" to format it correctly, then Ok.
    5) Now on the next screen click the checkbox to enable Full Control (this will also automatically enable "Read" permission too).
    6) Click Advanced, then the "Owner" tab at the top.  You will see that their is no "Current Owner".  This is what we will now fix.
    7) Click on your name to change the owner to (I went for Administrators).  Also enable the checkbox entitled "Replace Owner on subcontainers and objects".  Then click Ok.  You will get an error message, which you can try clicking Retry to, but hit Cancel - this is not a problem.
    8) Click Ok a couple of times and this part of your registry is now fixed.
    9) Now it's a simple case of running the manual Flash uninstall program, then finally the manual Flash installer (for Active X - not the Firefox/Chrome plugin versions).  To my surprise, after a couple of days looking into this - I finally had a solution and Flash in IE once more.  If you are using Firefox too you may find Flash is no longer installed their (the uninstaller removed it).  In this case just install via the Adobe site or try to watch a video on You Tube and you will be prompted or linked to the install.
    Hope this provides a good round up of the possible solutions to this problem.  Hopefully Microsoft or Adobe can find out what causes this issue in the first place so we don't have to go down this route for much longer.  Chrome's implementation of Flash shows how effortlessly things can work!

    They will stay on the screen.  However, Process Monitor is only intended for advanced users.  It is recommended that users try to navigate to the troublesome registry key using regedit, and see if they can access it or not without an error.  This is far easier than trying to use Process Monitor, which is very complicated.
    I used Process Monitor to confirm that it was just that key which was causing the problem, and not others.  Process Monitor is not to be confused with the new Resource Monitor which is accessible via Task Manager in Windows 7 (and possibly Vista).  If you must experiment (and Process Monitor is very useful for diagnosing many deep-level problems if you know what you're looking for) Process Monitor can be downloaded from here:
    http://technet.microsoft.com/en-us/sysinternals/bb896645
    It replaces the older Sysinternals "FileMon" and "RegMon".  For those interested in the technical side, I had to setup a number of filters to be able to get the results display as in the screenshot.  First of all to just show Registry events.  Then to just show events from the manual Flash activeX installer executable.  The I added a filter to show only non-successfull results.  And finally, for the purposes of the screenshot, added a filter to just show those with "Access Denied", since other non-critical errors are also picked up due to missing keys because installation has not yet been fully completed I guess.   When experimenting, most of these filters were applied using the "is not" boolean logic, which will make sense if you experiment with the program.
    Without adding any filters, it picks up so many events (hundreds per second) that it's otherwise unusable.  e.g. 40,000 events within the first few seconds of opening the program. For this reason, I recommend simply using Regedit to diagnose the problem with the particular Flash registry key.

    I have an HP Deskjet 3055A J611 Series, which is running on Windows 7.
    It is important that I scan several pages and place them all in one file.  I understand that this requires that I access the printer control panel.  I have accessed the printer through the icon "devices and printers",  and the panel that comes up have only the following 4 items:  am unable to scan from my printer control panel: HP Printer Assistant; See What's Printing; Set Preferences; Customize your Printer.  Perhaps this is not the control panel?  If not, then I do not know how to access the control panel.  On the other hand, if this is the control panel, then it does not have all of the icons and I do not know why.  Could you please help?  If I can't get this straightened out, I will need to find another printer that can easily scan documents with several pages onto one file.

  • ActiveX control for Flash Player could not be registered - no solutions work

    I am getting the "ActiveX control for Flash Player could not be registered" when I try to install 11 on IE9 (Windows 7 64-bit).  I have tried everything that has been suggested in other posts and forums to no avail.  This is driving me crazy and hindering me from work.  Can someone please help?  Thank you!

    I just had this issue and have been searching and searching for a way to fix this issue. I have a Windows 7 64 bit system and this was happening with IE 9. But I have found the solution.
    Go to http://kb2.adobe.com/cps/494/cpsid_49419.html and follow these instructions. This worked for my system and I was able top install the newest flash with no problems.
    Make sure you are logged into a Windows Administrator account. If you are not, you will not be able to use SubInACL.
    Download SubInACL from the Microsoft Download Center.
    Follow the installation instructions. Make sure you install SubInACL (subinacl.exe) to the directory C:\Program Files\Windows Resource Kits\Tools.
    Download the reset_fp10.zip file.
    Open the fp10.zip file and extract the reset_fp10.cmd file to the directory C:\Program Files\Windows Resource Kits\Tools\.
    Both this file and SubInACL (subinacl.exe) must be in this directory.
    Double-click reset_fp10.cmd. A command window will open, and SubInACL will run.
    Do not use the machine while SubInACL is running.
    After SubInACL finishes, you will see a prompt "Press any key to continue".
    Install Flash Player from the Flash Player download page.
    To confirm that your installation succeeded, visit the About Flash Player page. At the top of the screen, you should see a message that reads "Adobe Flash Player Successfully Installed."
