Troubles using Thread & repainting components at same time.

Hi. I have a frame which contains several labels. If i clicked on a label, it runs a method which changes label's aspect. Then, i need that once passed a second, label's aspect changes to original aspect. The problem is that controls dont repaint while i use Thread.sleep(1000) method. I have tried to call repaint() (both frame and label) before calling Thread.sleep() but it doesnt work too.
Any idea on how to solve this problem? Thanks for answers :)

Well, it wasnt a layout problem.
I've found solution trough camickr's link. Now im using Timer and TimerTask classes and all is working fine.
Thank you very much :)

How do i set up a second display for my iMac desktop? I want to use both displays at the same time.

how do i set up a second display for my iMac desktop? I want to use both displays at the same time. My iMac is the 24" Late 2006 model. I recall that there is a cord for plugging in a second monitor, but I want to make sure that i can use both monitors side-by-side at the same time. thank you.

If the Display supports DVI, then you will need a > Mini-DVI to DVI Adapter and a DVI cable.
If the Display only supports VGA, then you wiil need a > Mini DVI to VGA Adapter and a VGA cable.
Noting that the (digital) DVI is far better than the (analog) VGA connection.

Is it possible to have 2 threads running at the same time?

Is it possible to have 2 threads running at the same time at different times eg 1 repeats every 20 miliseconds and the other 40 for example. Also could you have 2 run() methods in one script, in one file? If so how? Help soon would be appreciated. Thanks.

Satelitte C55-A Can't Use Keyboard and Mousepad at same time

How do I change the settings so that I can use them both at the same time? I use them both for all my games, but I can't turn with my mouse pad when im walking with my keyboard keys (W,A,S,D). Does anyone know how to change this?
I'm on Windows 8 btw.
Thanks,
-Evan

There should be a setting for that in Mouse Properties, Evan. Something like "Disable touchpad while typing."
Also, it's a "feature" of Windows 8.1.
Button clicks for internal touchpads and pointing sticks are not responsive while or shortly after t...
Windows 8.1 introduces a feature that is called accidental activation prevention (AAP). AAP helps ensure that unintended taps while you type on an integrated touchpad are suppressed. When this feature is enabled, taps and clicks from an integrated touchpad or pointing stick are suppressed for a while after the last keystroke..

Will my whole itunes library be transferred to my new computer with home sharing,in other words will I be able to use bothe computers at the same time ? And will I have two copies of my all my playlists?

Will my whole itunes library be transferred to my new computer with home sharing,in other words will I be able to use bothe computers at the same time ? And will I have two copies of my all my playlists?

Hi there J1750oe,
You may find the information in the article below helpful.
iTunes: How to move your music to a new computer
http://support.apple.com/kb/ht4527
Transferring playlists
If you want not only your content but also your playlists to exist on your new computer, you will want to transfer a copy of all your playlists from your old computer. To do this, choose File > Library > Export Library on your old computer. Save the XML file that is created to your desktop.
Send the playlists file to yourself as an e-mail attachment, use an external drive, or use file sharing to move the playlists file to your new computer. Once the file is on your new computer, open iTunes and choose File > Library > Import Playlist. The import process will remove any items from the playlists that you didn't share via Home Sharing.

Can you stream video and use the computer at the same time on a mac mini with hdmi

Can you steam video and use the computer at the same time? I have a mac mini with hdmi.

Shouldn't be a problem, unless you want to view it in Full Screen Mode at the same time with only one display.

Using multi-threading: Setting a VI to be used for two sequences at same time

I have two sequences running as two different threads. This is supposed to be in parallel but both sequences access the same VI, then they're not executing as parallel because one sequence use this VI then liberates it and the other sequence use it, and so on consecutively until both sequences finish. This is not what I want.
How can I do to set this VI with any kind of property or something that can be accessed for both sequences at the same time?
Thanks,

Hi Margarita, you can set a VI to be reentrant (under VI Setup»Execution Options from TestStand, this function can also be used from LabVIEW) . Now depending on the king of VI you are using this can be something safe or can cause trouble. If the VI needs to keep information (for example a Functional Global Variable) or it is handling Hardware it can give you errors (for example trying to access the same DAQ at the same time from different task.
If you need more information can you tell us what does this VI does?

Streaming from ipod/ipad to ATV2 interrupted when using other apps at the same time.

Hi. I have an Apple TV2, ipad1 and ipod touch4. I am having trouble with music streaming to the ATV2. I can select a song on the ipad/itouch and stream it to the ATV2 no problem using airplay. However, if I then try to surf the net on the ipad/itouch or use any other app at the same time as listening to the music, the music hiccups. It seems to me like the ipad/itouch need to use the wifi network at the same time and so they take over the signal momentarily. Any ideas what I can do about this? My wireless router is a dual band 2.4 and 5 mhz gigabit router that is brand new and should not have any problems.
Thanks
Julia

Ferrell, I have done what you suggested. I clicked onto the Spaces icon in the upper control panel and assigned spaces to six apps: Mail, Safari, iPhoto, iMovie, Pages, and iWeb.
The problem is that if I am one app and I want to put something into that app, then the minute my mouse cursor goes to get that other thing, the original application into which I want the thing put GETS WHOOSHED OFF THE DESKTOP. What I want is for the original app to remain open whilst I go to retrieve a file or folder, and stay open while I put that thing into the original app.
How does one turn off Spaces? I don't mean to delete all the names from the settings.I mean, just turn it off for a while so I can do something which requires for two apps to be open at the same time????

How to use multiple languages at the same time for spell checking?

I use two different languages all the time and words are mostly so different (English and Finnish) that I could have spell checking on for both languages at the same time.
Now it seem to allow to select only one language at the time and I have to switch back and fort zillion of times per day.

Thanks for the quick answer.
The Dictionary Switcher doesn't seem to work with Finnish language, it doesn't detect it at all to be one of the choices although in the Firefox context menu Languages -> Finnish/Finland is shown.
Also, if it would work, I would need to get rid of multiple EN_* langauges. I just need EN_UK or EN_US, not all 22 different EN_*.
One option would be to create a custom dictionary, which would have words from both languages. The next task is then to find out how to make this kind of custom ENFI-dictionary, which would have words from both English and Finnish languages.
Finnish may be a some kind of special case for spell checking anyway, because the support is in its separate plugin:

Is there a way I can stream video from my 2012 AirMac to the Apple TV using airplay and at the same time stream the audio to an air speaker?

Is there a way stream video from a 2012 MacBook Air to a TV using Apple TV and at the same time steam the audio to an air speaker. Also the same question but using an ipad

You can try one thing. Follow these steps:
1. On your Mac, turn on AirPlay Mirroring and connect it to the Apple TV, so audio and video will stream from the Apple TV.
2. Turn off the sound of the TV where you have connected the Apple TV.
3. Then, make sure that you have turned on the AirPlay speakers. Then, open System Preferences > Sound > Output, and choose the external speakers, so sound will stream from these external speakers.
This should work correctly

I want to apply the function like this:
1.config the port1 and port2

After I open the second port it always returns negative.
In the codes I use CAN0 and CAN1 as the CAN objects.
