Working in the background and Displaying an image on top of everything

Hi,
I have two question
1-) How can I implement a program which would run in the background. For example while I am writing a document, my program will print the entered keys on the console.
2-) How can I draw an image without using Frames or anything else. For example most of the monitors have birghtness property etc, when you press the buttons on your monitor, the menu for properties appear on everything, I want to implement something like that.
Thanks for help.

  • Loading an image in the background and displaying it as it is loaded

    Hi,
    I'm writing an "image viewer" swing component, which should load an image in the background, and display it as it is loaded (for example each time a line of the image is loaded, display it)
    Is there a way to do this using JAI or any other api ?
    I guess i would need a way to check the loading progress from the EDT, get the loaded part of the image and display it. Am I right ? Is that possible ?
    Thanks,
    Nicolas

    In the video inspector set the Spatial Conform to "none". This will give tou the actual size of the image in the viewer. You can then use the transform controls to adjust the image to what you want to see.

  • TWO CRITICAL BUGS: 1) File, "Save Page As" and 2) right-click the picture and select "Save Image As", both do not work at all in Firefox 27, 28, and 29!

    Note: capitals are used only to highlight important words.
    PLEASE, TAKE THESE COMMENTS ON TWO CRITICAL BUGS VERY SERIOUSLY BECAUSE THE BUGS DESCRIBED BELOW ARE SO CRITICAL THAT I CANNOT USE THE LATEST VERSION OF FIREFOX UNLESS THEY DO NOT APPEAR IN THE LATEST VERSION AND THEREFORE I AM FORCED TO REVERT BACK TO FIREFOX 26.
    I have Windows 7 64-bit and Firefox 26. I could not install Firefox 27, 28, and 29 due to the persistent presence of the two critical bugs described below. I have 8 GB of RAM and an Intel quad-core processor and a lot of hard disk space available.
    I installed Firefox 27 and then Firefox 28 a while back and these two bugs described below were still present and now I have just checked again with Firefox 29 by installing it and yet again, these two bugs described below are present!! UNBELIEVABLE THAT THESE TWO CRITICAL BUGS ARE STILL PRESENT IN FIREFOX 29 WHEN I CLEARLY INFORMED YOU ABOUT THEM IN THE HELP, SUBMIT LINK OF FIREFOX!!
    I am forced to revert to Firefox 26!
    First, I use Windows 7 64-bit and I always use Firefox with at least 120 tabs opened. BUT I have 8 GB of RAM, an Intel core i7 quad-core processor and more than 1 TB of hard disk space. Consequently, I do not understand why I would have these two critical bugs.
    With Firefox 26, I also have at least 120 tabs opened when I start Firefox and I do not have the two critical bugs described below, therefore I do not believe that the number of tabs is the reason of the two critical bugs that are present in Firefox 27, 28, and 29.
    ---FIRST CRITICAL BUG:
    When I open ANY web page and do File, "Save Page As", the window that is supposed to open to locate the folder where I want to save this web page does NOT open at all, even if I wait a long time to see if it opens.
    Same problem happened with Firefox 27, 28, and now 29!! When I reverted back to Firefox 26, this problem did NOT happen anymore!
    ---SECOND CRITICAL BUG:
    When I use Google Images, for instance entering model in the search field of Google Images and then pressing enter.
    Then I select any picture, open to a new tab this selected picture, then open a new tab by selecting the option View for this picture. Then right-click the picture and select "Save Image As".
    Again, the window that is supposed to open to locate the folder where I want to save this picture does NOT open at all, even if I wait a long time to see if it opens.
    Same problem happened with Firefox 27, 28, and now 29!! When I reverted back to Firefox 26, this problem did NOT happen anymore!
    ---THESE TWO CRITICAL BUGS DO NOT APPEAR WHEN I USE INTERNET EXPLORER 11.
    I have no idea if you will be able to reproduce these two critical BUGS but I can assure you that they are not present when I use Firefox 26 and they are present when I use Firefox 27, 28, and 29. More, be aware that I have at least 100 tabs opened but I also have this same number of tabs opened in Firefox 26 and yet I do not experience these two critical bugs when I have Firefox 26!
    Once again, these two bugs touch at two vital, critical very basic functions of Firefox and therefore I will NOT be able to use any version above 26 if these two bugs are still present, as they are present in Firefox 27, 28, and now 29!!!
    Please, make it a priority to solve these two critical bugs. Thanks.
    I did read a post related to the same issues “Firefox stops responding when trying to "save page" or "save image" | Firefox Support Forum | Mozilla Support” at https://support.mozilla.org/en-US/questions/991630?esab=a&as=aaq
    I am still reading it again to try to figure out exactly what the person did to make his problems be solved, as the post is not clear at all on what solved the problems!
    In any case, all the suggestions proposed in this post do not work and I surely cannot do a system restore when it is obvious that the two bugs do not appear in Internet Explorer.

    First, I sent an email to the author of PhotoME to inform him of the serious issues his addon caused with Firefox latest versions.
    Now, for those of you who do not have the PhotoME addon and yet experience the same problem that I had and that I described above, I suggest the following strategy.
    As PhotoME did cause these problems with Firefox latest versions, I am pretty covinved other addons probably might cause these problems too. Therefore, adopt the following method.
    Test one addon at a time to see if this particular addon is behind your Firefox issues like the ones I had.
    So, disable one addon only at a time. Then close your Firefox and restart it from scratch and see if you still have your Firefox problems. You must restart the Firefox browser from scratch. If you still have these Firefox problems, re-enable the disabled addon, restart your Firefox (again!) and repeat the same method for every single addon that you have.
    Try to be selective by choosing first addons that are more likely to cause your Firefox problems such as not very well-known or not very popular addons (like it was the case for the PhotoME addon).
    If this method works or if it does not work, report it on this web page so that others can be helped with your comments.
    I hope this method will help you because I was really upset that I had these Firefox problems and I first thought it was the fault of Firefox, only to discover later that this PhotoME addon was the culprit and had caused me such upset.

    Hi Paola,
    if you own IMAQ Vision you can just have a look at the examples that comes with your board or you can look at: http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/2abaefe05789961686256866007c0d22?OpenDocument.
    Without IMAQ Vision look at:

  • Need help with working in the background while doing a presentation

    Hi guys,
    I wanted to know if my MBP had a way to let me do a presentation, where on my screen I could tell it to present what I wanted it to present rather than showing every single move that I would make. If for instance, I were to open an app for looking up something to present, I wouldn't want people to see that action, but rather the things that I would put on a special window or virtual place created just for that.
    Maybe there's an app that will let me do this? What happens to me know is that when I connect the MBP to the data show presenter, everything I do gets displayed on the big screen on the wall. I want to work in the background without people seeing that. Please help. Thanks.

    The system software makes it about as easy as possible. Press fn+F7 (the pictographic mnemonic on the F7 kety is two overlapping rectangles). This will toggle the display mode between mirroring (same image on internal and external display) and spanning (each display independently contributing to the total viewable area).
    As a bonus when using Keynote (the presentation software from iWork) in a dual-screen configuration, you get one display showing the presentation and the other showing you context (the upcoming slide) and a timer. Check out the demo included with you MacBook.

  • The bar at the top of the page wich displays ,WEB, IMAGES. VIDIO etc is now black Why

    The bar at the top of the page wich displays ,WEB, IMAGES. VIDIO ect is now with a black background which is hard to see,why would the colour have changed and can I change it back?

    I did some investigation yesterday and found that is is caused by a change made by Google.
    Google regularly does some experiments and makes changes.

    I'm a new user and learning, I bought and installed Premiere Pro cs6.  I got a nice video clip but has a baby cried in the background and very annoying.  I have tried all of the sounds in Prem cs6 but didn't work. My question is, do I need to get a separate sound software download and install to be able to use it?

    In the CS versions, there was some audio capability in PrPro but you needed to get a separate audio program for major work. Lessening a baby definitely qualifies as major work. That's lessening, i dont mean eliminating. Adobe's audio program is Audition. There are others "out there'. In the CC versions one just downloads Audution also.

    If not, is there any adaptor i can use to make it work.
    I also have the new MBA with thunderbolt socket.
    Cannot decide which display to get.

  • Every time I TRY to start firefox 18-19 I get an error message : Firefox has stopped working - close the program and check online for a solution - or - close ..

    Every time I TRY to start firefox 18-19 I get an error message : "Firefox has stopped working" - "close the program and check online for a solution" - or - "close the program" this happens TWICE every time I try to start firefox. Eventually after a random number of tries firefox will start normaly. I am useing firefox 19.0.2 now bit I belive it started when I upgraded to firefox 18 but am not sure, it might have been when I upgraded to firefox 19 ... but it has been happening for a very long time and I cannot find any helpfule solutions online.
    I have tried a Clean reinstall but it did not help.

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
    Thank you.
