    Hi Everyone, I am new to Java Programming.
    I wanted to know if there is a way to get all the images in a website and put them in a listbox. And if an item is clicked in list box, view it in a picturebox.

    unfortunately, .net is essentially a clone of java so you may find that you will be looking

  • Is it possible to get the image from the i pad when mirroring via Apple TV to fill the screen instead of appearing as a screen within a screen?

    When mirroring, is it possible to get the image from the ipad to fill the screen on the TV instead of appearing as a screen within a screen?

    Welcome to the Apple Community.
    No, the iPad has an aspect ratio of 4:3, a TV has an aspect ratio of 16:9, to fit one into the other is impossible without distorting the picture. If your TV has a zoom feature, you may be able to use this to fill the screen a little more to your liking, but this will result in cropping top and bottom.

  • How can I get an image from the screen? Like screen printer in PC to pasting after in word or other program.

    How can I get an image from the screen? Like screen printer in PC to pasting after in word or other program.

    If you do Cmd+Shift+3 you'll get a full screen image saved to your desktop as a jpg file.
    Also, you can use Cmd+Shift+4 and you'll get a cursor which you click+drag to draw a box. When you release the drag the boxed in area will be saved to the Desktop as a jpg file.

    How can I keep people from saving images from my website?

    Hi,
    have a look at this thread
    http://discussions.apple.com/thread.jspa?messageID=5645821&tstart=0#5645821
    and the link I posted in that thread
    However there's no way to avoid that people grab photos from your website. Nevertheless there are ways for making it a little more difficult.

  • When i save any image from any website then there is no option showing in the save as box like saves as .jpg etc. In this case I manually add the extension of image for example .jpg .gif etc. Please solve my problem :(

    I'm guessing your problem is caused by code validation errors: orphaned division tags for example, or mismatched code and document type (i.e.  XHTML /> mixed with HTML > style closures).
    Start by using the code validation tools below and fix any reported.  You'll need an Internet connection for this:
    HTML Validator - http://validator.w3.org 
    CSS Validator - http://jigsaw.w3.org/css-validator/  
    HTML & CSS Tutorials - http://w3schools.com/
    If this doesn't solve the problem, you will need to post a URL to your live page so we can see your code and images working together.   Or at the very least copy and paste your HTML and CSS code into a reply using double arrows >> Syntax Highlighting > Plain.

    Hi,
    Which website your are using to update the Adobe Flash player? No Adobe website ever ask for any id and password to update the flash player.
    If you are using MAC machine and its the password prompt while installing update that you are talking about then please follow What userid & password do I need to install Flash Player?

  • I accidentally blocked images from a website (facebook) how do i fix it?

    i accidentally blocked images from a website (facebook) how do i fix it?

    With Facebook on display, click on the [[site identity button]] and then on More Information. This will open up the page info dialog.
    First select the Permissions panel, make sure that "Load Images" is set to allow (selecting Use Default should also work)
    Next select the Media panel, then click on the first item in the list. Use the down arrow key to scroll through the list. If any item has the option "Block images from (domain name)" selected, de-select the option.
    This should hopefully resolve your issue, but also see [[Images or animations do not show]].

  • Saving images from a website using macbook

    I need to save an image from a specific website when I right click on the image (control click) a menu pops up with the following options:
    Settings....
    Global settings...
    About adobe flash player
    It also does not work to simply slide the image to my desktop.

    It sounds like the image isn't simply an image, but is really Flash content.  I'd recommend taking a screenshot (see this post for details on how to do this depending on your OS) if you can't get to the original jpg/png/gif/etc.

  • After updating to 12.0, I can't copy and paste images from any website; instead of the image pasting, the URL for the image pastes instead; help, please?

    This applies to copying from any website, and pasting to any and all applications. This is exactly coincidental to install of 12.0. This is a basic, common, and essential function of any web browser. I've read various unacceptable "workarounds" in a couple posts, and am respectfully requesting a truly professional response from Firefox re: what exactly can be done to restore this basic, elementary function. I have been a major Firefox fan up until now, and need it to provide this basic functionality in a dependable way - simple right-click, copy image, and paste the image (not it's URL). Thanks for helping (hopefully).

    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
