How to determine which application has focus in Windows

Hello all-

I'm trying to work around the "Labview freezes when there is big data in the Clipboard, known issue" (http://forums.ni.com/t5/LabVIEW/Labview-freeze-when-accessing-a-custom-menu-with-data-on-the/m-p/200...) and a thought is to try to determine if Labview has the focus, and if it then clears the Clipboard.  If Labview has focus, and then let the user use the Clipboard.  It would be a good work around, because it would let users paste the screenshots and notes files and would not risk a nasty Clipboard / menu / gel-crash.

My initial search for determining windows application focus, came so empty.  This old thread (from 2005) covers pretty well:

http://forums.NI.com/T5/LabVIEW/is-there-a-simple-way-to-programatically-tell-which-VI-window/m-p/20...

The "is more"property disobeys.»  I must determine if Labview has the focus, as opposed to Windows, Notepad, firefox, etc.  I also looked at command prompt commands and found nothing immediately useful here either.

Any ideas?

Thank you

Casey

Hello

You can use the GetForegroundWindow starting from user32.dll. More information on msdn.

  • How can I determine which applications and processes are turned on at first upward and how can I keep their autostart?

    My office of gateway using Windows XP takes a long time to start.  I hear a lot of activity because it starts and after a very long time, I can really use it.  I would like to know what process or applications start automatically and then determine which ones to move away and how.

    If you were to Google something like:

    XP boot manager

    You will get hits with links to managers of free starter like this simple:

    http://www.MLIN.NET/StartupCPL.shtml

    Another popular and free tool with a built-in startup manager (and other interesting things) are CCleaner which you can download here:
    http://www.Piriform.com/CCleaner

    CCleaner allows you to manage most of the startup items and also do some other operations oriented cleaning.  Some people will you recommend is not to use the registry functions in CCleaner to avoid these features for now.  I have no problem with it for me, but sometimes it's a contentious issue, I prefer to avoid as much as possible!

    You can uninstall CCleaner later if you don't like it.

    You can disable the startup items, see how things look and if you want - you just delete them (or leave it off).

    After launch of CCleaner and see what startup items you can disable/remove, if you are still not sure of your startup items, follow these steps:

    Run CCleaner and choose Tools, boot and bottom right, click on the button "Save to text file" to save the startup information in a text - something like startup.txt file

    Save the boot information text file on your desktop (or somewhere you can find it) open the text file with an editor (Notepad or WordPad), select all (Ctrl-A), copy text, all the text selected in the Windows Clipboard (Ctrl-C) and then paste (Ctrl + V) the contents of the startup list to come back here in your next reply and maybe someone can tell you another thing to consider.

    A more revealing startup Analyzer is Autoruns which will allow the manipulation of all sectors of boot and does not actually install anything:

    I have zero startup items on my computer, so none of this is important to me!

  • OIM:how I can determine which user has ' revoke if applies "set

    IOM how can I determine which users have "revoke if applies" defined on any of their policies? I can't see where it is set on the policy itself, but this setting appears to follow user not politics. I want to say, if I apply a policy to a user, even if this flag is set, then turn off the flag and remove the policy from the user, the resource is always cancelled even if politics is going not to do. I need to find in the database this setting (strategy/user) storage so I can't disable it on all users who still have on any of their policies.

  • How to determine which were installed the SP3 and IE8

    I'm working on a friend's computer troubleshooting. I plan to roll back of IE8 to IE7 (or it might even be IE6). However, I want to just try this if I know for sure that IE6 has been upgraded AFTER SP3 has been applied.

    I am trying to determine where these updates have been made. I thought that if I went into Add / Remove Programs, I would get this information here, but alas, he's not here.

    So, what is the method for determining when IE6 or IE7 has been upgraded to IE8 and how do I determine when SP3 has been applied?

    Thank you!

  • Determine which application is downloaded from the Internet

    In the Task Manager Networking tab, I see continuous activity even if I'm not especially communicate via the web browsing or chat MSN. The speed of activity is slow (about 10-20 Kbps), but still.

    Sometimes the real-time scanning my antivirus (Symantec) informs me of a virus found in a file that was successfully deleted from the queue, or the file has been deleted.

    I suspect that these two problems are related.

    Please see the information from Microsoft on how to determine the operating system that you have installed.
    http://Windows.Microsoft.com/en-us/Windows7/help/which-version-of-the-Windows-operating-system-am-i-running

    If the system page does not list a Service pack version number, you don't have a service pack installed on this computer.

    Hello

    As far as I can see there no edition information in the YES program.

    But since you have installed forms, in my view, it must be an Enterprise edition.

    >
    Components = Apache, J2EE, WebCache, JServ, portal, wireless, discoverer, customization, reports, forms
    >

    Forms is only available with Enterprise Edition:

    Almost certainly an indication that a disc is a failure and should be
    replaced as soon as POSSIBLE.

    I get 4 hard drives and would like to know how to determine who makes clicking sounds.

    Does anyone have any suggestions?

    1. open the case and disconnect the power cables of all readers but
    C:, then run the computer for awhile. If we click, it is C: this is
    dying.

    2. then plug the power cable into a different drive and run it
    computer for a while. If you click on, it's that you reconnected
    who is dying.

    3, number 2 twice more if necessary to repeat.

    Hi Revbob,

    1 did you recent hardware or changes to the software of the system?

    2. are you able to boot into normal mode after receiving the error message?

    If you can boot into normal mode, you can try to perform a clean boot and see if it helps.

    A clean boot to check if startup item or services to third-party application is causing this issue.

    You can read the following article to put the computer in a clean boot:
