Why Doesn't LabVIEW Intercept the WM_SYSCOMMAND Windows Message?

I am using the Windows Messaging vi's to try to defeat the screen saver from automatically starting (our IT people have locked us out of controlling our own screen saver). I have read that if I can dequeue the SC_SCREENSAVE message from the WM_SYSCOMMAND message I can prevent the screen saver from starting. The problem is that these vi's don't seem to be able to read WM_SYSCOMMAND messages. It works great for mouse movements but nothing more. Any help would be greatly appreciated.

Well I had some time this afternoon and little else to do so I coded up a quick application for you to use
I tried it too just out of curiosity and it also didn’t stop the screen saver.
We have no restrictions on our PCs, full admin privileges. This is on XP Pro SP2.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

  • Why my form doesn't fit in the navigator window?

    Why my form doesn't fit in the navigator window?.
    When I execute the form from navigator the form appears in but the size is less than the size of the explorer and shows shows vertical and horizontal scrollbars. What can I do to avoid this?, Is there any solution different than modify all my forms?, Is there any way to configure my navigator?
    Sorry if I'm slighty off topic

    We also faced this problem but now we have made changes in formsweb.cfg file by setting SeprateScreen=true value and restarting form server.
    This will open forms in new window instead of same.
    I hope this will work for you also.

  • Why doesn't my itunes on my windows pc load on my apple tv?  Home sharing is turned on and my ipad can see it!

    Intermittent problems
    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.
    Consistent Problems
    A frequent cause of consistent failure to enable AirPlay or HomeSharing at all, is the service being blocked on the network. Make sure your network isn't hidden, has a unique name, that MAC address authentication is disabled, security is set to use WPA 2 Personal and that there is only one router/device acting as a DHCP server and providing NAT services.
    Make sure your router/computer allows access over the following ports

    Refer to your router manual/manufacturer for any settings that are specific to that model.
    Another frequent cause of consistent failure to enable AirPlay or HomeSharing at all, is security software, in many cases configuring it correctly, disabling it or even uninstalling it can help, but in some cases the security software can cause problems that simply reconfiguring, disabling or uninstalling cannot reverse.
    If you are consistently unable to activate AirPlay, have tried all the steps in this article and have security software installed on your system, you might benefit from contacting its provider or participating in any online forums they run to discuss the matter with them.

  • Labview as the active window disables 1 or 2 concurrent while loops

    I am trying to get familiar with new mutltifunction DAQ hardware from IOtech - a DAQborad/2000.
    I have a simple vi consisting of two while loops which should be running in parallel. One acquires analog input data, the other handles DAC outputs.
    When I run the vi, the analog acquisition while loop runs fine, but the DAC while loop will not run if labview is the active window on the pc (frontpanel or diagram). If I make another window active, both loops will update as they should.
    I can resize a windows explorer window to make it small, run my vi, make windows explorer the active window and see the vi running both loops and updating as it should in the background. If I use the "Highlight Executi
    on" tool on the diagram screen, both loops run as they should.
    Any ideas?
    Thanks,
    Mike

    Many third party drivers default to running in LV's UI thread, and if
    they put the thread to sleep, other LV threads can run, but not the UI.
    It is also possible that one of the loops is hogging while the other
    is being starved.
    So, I've got two suggestions to try. First try putting a delay of a few
    ms in the busy loop. This might help with the starvation. The second
    thing to try is to open up the IOTech VI and try setting the DLL node to
    be reentrant. This will allow the node to run in any thread and not
    force it into the UI thread. Beware that if the DLL isn't threadsafe,
    this could lead to data corruption or crashes, and before leaving it s
    et
    this way, you should probably contact IOTech to see if their DLL is
    threadsafe. If it is not, contact NI tech support and they can help you
    determine if it is safe in this case to leave it running in other threads.

  • Why doesn't Apple list the changes in iPhone updates?

    Why doesn't Apple list the changes included with each iteration of iPhone updates? They always post a detailed list of changes for all other major software updates. I wonder why the same is not true for the iPhone, leaving us all guessing and wondering...

    Just to add, Ansuz82 pointed out, Apple's track record is that they don't really ever give full published details about what their updates include in any of their products really. If the iPhone is your first product by Apple you may not be aware of this. To them, saying Bug Fixes is enough. If they publicly add more info, it means they really wanted to get that point out. eg: the 1.1.1 mainly just talked about iTunes WiFi store. 1.1.2 mainly talked about the Tiff exploit fixed and keyboard updates for languages. However, with all, a lot more does get changed than just the key points mentioned. And by a lot, I don't mean a lot that you will see. Have to remember, they are still ironing out the OS for the iPhone. A lot of changes to them is just cleaning up and fixing known bugs that many of us as users may not even know exisit (though we see the outcome of them when apps colide and crash each other).

  • The Cube with ID = Rate doesn't exist in the collection Error Message

    When doing a Full Optimization in the Rate cube I get a "The Cube with ID = Rate doesn't exist in the collection" error message. What is causing this error and how do I fix it?

    I have seen this error when reporting services was not properly configured. can you connect to http://servername/reports ?
    If not try to fix reporting services first, this solved the problem for me in the past.
    But usually in this case all the aplications are giving this error when modifying. Is this also the case in your appset?
    Does Apshell work when you modify the application there?

  • Does Adobe Send allow you to select how many days your files can be downloaded - as with Adobe Send Now? Also, why don't I see the virus scanning message any longer with "Send" versus "Send Now"?

    Does Adobe Send allow you to select how many days your files can be downloaded - as with Adobe Send Now? Also, why don't I see the virus scanning message any longer with "Send" versus "Send Now"?

    We relied upon the "days available for download" to get people to take
    action more quickly. The "virus scanning" progress bar was simply another
    way of knowing this activity was actually taking place - unless this is
    written somewhere in the Adobe Send User Guide.....wherever that is.

    Right now on my screen I have two Finder windows. One is partially covered by the other.

  • Running an EXE from LABVIEW without the 'cmd' window showing

    Hi,
    I am currently using the 'system exec.vi' in a LabVIEW application to open files in external executables (mainly Windows Explorer, Acrobat Reader and Word).  This actually works fine and while my application is fairly sleek (even if I do say so myself) I am annoyed by the cmd window that momentarily appears each time I use the 'system exec.vi'.
    Is there any way to disable this window?  Or maybe there is another way of opening the files altogether?
    I am using LabVIEW 8.0 on Windows XP Pro.
    Any help would be appreciated.

    Thankyou for your comments...
    I do buy LV as part of a developer suite so could use the toolkit you mentioned.  While PDF's and Word docs are the main files I open they are not the only.  I guess I could open different file types different ways.  I just hoped there was a better all round way to do it.
    As far as Windows Explorer goes...  My application is a file manager targetted directly at the file structures we use for developing functional test applications.  The application handles all the file management requirements (i.e. WIP Backups, deploying, zipping/archiving etc) and its an added feature that you can 'explore' a given folder directly from the application.  The general idea is that all our developers create systems using the same structure and approach.

    Have you looked at the VI in vi.lib\Platform\browser.llb\Open a Document on Disk.vi. It opens the document passed in according to its file ending and attempts to communicate with the target application through DDE if possible before using the command line. Even then I have not seen a cmd window popup so far.

  • Why doesn't Flash have the option to publish to .flv?

    Why doesn't Flash or Adobe Media Encoder have the option to publish or covert .swf to .flv?
    Any suggestions on free .swf to .flv coverters?

    Thanks, kowboy.  I've just seen a few of those video conversion tools that specifically advertise .swf to .flv conversion.  They may degrade the quality and make certain features not work just like when you convert to .avi.  I was wondering if anyone has had any experience with any of those tools.
    I know this is a fairly odd situation.  Both myself and the other flash developer advised that they not use Flash to create 5 min plus videos and then wrap them in .flv flash players.

  • Why doesn't reflection reveal the clone() method in arrays?

    I was surprised to discover that the following code does not reveal the method "clone()", even though you can call "clone()" on an Object[]. Can anyone explain why this is? I was hoping to use the Reflect API to clone an arbitrary object if it was Cloneable, and to throw an Exception otherwise. How can I do this?
    import java.lang.reflect.Method;
    public class Test {
         public static void main(String[] args) throws Exception {
              Object x;
              //pick a class
              x = new Object[] {};
              //is it Cloneable?
              System.out.print("The class " + x.getClass().getCanonicalName() + " is ");
              if(!(x instanceof Cloneable)) System.out.print("NOT ");
              System.out.println("Cloneable");
              System.out.println("-------");
              //what methods are available?
              Method[] meths = x.getClass().getMethods();
              for(Method m : meths) {
                   System.out.println(m.getName());
              System.out.println("-------");
    }

    Just to clarify. I know that clone() is protected in Object, but it is certainly a public method in array objects such as int[], float[], Object[] etc. Test: call clone() on any of these objects! Also, I realize that Cloneable does not itself guarantee the method clone(). Nevertheless, if you take a regular Cloneable object, such as a String, then typically, if you ran myObject.getClass().getMethods() on that object, you'd find the method clone() in the resulting list. i.e., that Class has overwritten Object's protected clone() method with a public clone() method. So since int[], float[] and all the rest have a clearly public clone() method, then why doesn't myFloatArray.getClass().getMethods() show me a method called "clone"? I guess it would have to have something to do with the fact that arrays are funny kinds of classes that are not properly handled by the Reflection API, but is it on purpose that clone() isn't available?

  • Why doesn't Mozilla fix the Yahoo problem - it is a hacking issue?

    Dozens of people have strongly complained about Yahoo inserting itself in Firefox and hiding itself so it cannot be removed. This has been going on for at least a month.
    Why doesn't Mozilla do something to prevent Yahoo from HACKING into Firefox.? It is an obvious attempt to pre-empt people's browser of choice. Surely there is someone in the Mozilla group who can either alter the code to block Yahoo or at least come up with a solution that lets the average user remove the stupid Yahoo software.
    Thanks

    What a pathetic joke - the instructions to remove the unwanted Yahoo search engine tell you to open up the search engine list and remove Yahoo. BUT YAHOO IS NOT DISPLAYED IT IS HIDDEN AND CANNOT BE REMOVED.
    That horrible fact is what is so annoying. It is willfully hidden by either Mozilla or Yahoo forcing it down the throats of people who do not want it!!
    And a search on one's entire system does not turn up any reference to Yahoo.
    ONE MORE TIME, THIS IS MY COMPUTER NOT MOZILLA'S OR YAHOO'S.
    Please do what you know perfectly well is the right thing to do and provide a viable method for users to get rid of Yahoo.
    Why, Alice, can't you specifically answer my questions instead of spouting the drivel about providing features for a broad range of customers. There are hundreds if not thousands of user that are not happy about this stupid problem.

  • Why doesn't Photoshop display the full image on open?

    I'm using Photoshop CC on a MacBook Pro with OS X 10.9.2 and an external monitor, and when I open an image, it is partially hidden by the display window - scroll bars appear along the sides of the image display window. It's a little annoying, but hasn't been a big problem - I can just resize the display window. However, when I run a script to place an image, the image is placed in the center of the window rather than the center of the actual image, so the placed image ends up being cropped off the base image. The images I'm using are not large, 650 x 296 pixels at 72dpi, and take up less than 1/4 of the screen at 100%.
    I've tried adding scripts like http://www.ps-scripts.com/bb/download/file.php?id=10&sid=adf04fde6ee2c 103cddbc41220d6c3b3 and http://morris-photographics.com/photoshop/scripts/view-pixels.html, but they had no impact on the opening of the files.
    How can I get the display window to show the entire image automatically when I open it? Thank you.

    I'm not familiar with coding script - do you have a suggestion as to what I might try? The Fit to Screen script works when I open an image from Finder, but it does not activate when I run a Automate Batch. The placed image still gets cropped.

  • Why doesn't iTunes allow the podcasts to be downloaded by Release Date?

    I am using iTunes 11.0.2 (25) on my iMac (2010).  I am curious why iTunes does not allow the podcasts to be downloaded by Release Date?
    It will help me so much when I create the playlists by Release Date especially when I download the podcasts after their releases.
    Please advice and thank you.

    I find that this setting does remove any podcasts that I have already listened to at the time of the next refresh, provided that I have not told iTunes not to delete the podcast (right-click, Do Not Auto Delete). If you need it gone right away, try hitting the refresh button.
