How can I use removeAllCachedResponses in Cocoa-Applescript?

How can I clear the cache of a Webview in Cocoa-Applescript using this method?

Well, webviews can get very complicated depending on what you are doing.  Your application will cache its own stuff in your user's ~/Library/Caches folder, so you don't need to set up anything extra for that, anyway.
The removeAllCachedResponses method doesn't seem to work all that well (emptying caches in Safari doesn't either), but setting the cache size to zero won't save anything and will just result in the default cache files, for example:
set sharedCache to current application's NSURLCache's alloc's initWithMemoryCapacity:0 diskCapacity:0 diskPath:(missing value)
current application's NSURLCache's setSharedURLCache:sharedCache
I suppose you could also do what the Safari Cookies plugin does and just manually delete the caches when the program exits.

  • How can I use Applescript to copy a file's icon to the clipboard?

    Hello,
    How can I use Applescript to copy a file's icon to the clipboard?
    Thanks.
    Lennox

    there is no way to do that that I know of. but you can extract an icon of a file to another file using command line tool [osxutils|http://sourceforge.net/projects/osxutils]. you can then call the relevant command from apple script using "do shell script".

  • How can I use AppleScript Studio to display an image

    How can I use AppleScript Studio to display an image in a dialog?

    Add an image well to your window in Interface Builder.
    You can also add an image file to the Resources group of your Xcode project and then set the image to be displayed inside the image well directly in Interface Builder. No AppleScript code is needed if the image is contained within your app bundle and can be set ahead of time like this.
    If the image is contained in your app's bundle but you need to set or change the image at run time then you can use a line of AppleScript to load it into the image well using just it's filename:
    set image of image view "yourImageView" of window "yourWindow" to load image "YourImageFile.jpg"
    If you need to load an image from an arbitrary location outside your app's bundle then use a path to the image file...
    set image of image view "yourImageView" of window "yourWindow" to load image "/path/to/YourImageFile.jpg"

  • How can I use Automator to extract specific Data from a text file?

    I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
    How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
    Example of File Contents:
    Link Time =
    DD/MMM/YYYY
    Random
    Text
    161 179
    bytes of CODE    memory (+                68 range fill )

    1 875
    bytes of XDATA   memory (+ 1 855 absolute )
    90 783

    Hello
    You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
    set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
    if f ends with "/" then set f to f's text 1 thru -2
    do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
    use strict;
    use open IN => ':crlf';
    chdir $ARGV[0] or die qq($!);
    local $/ = qq(\\0);
    my @ff = map {chomp; $_} qx(find . -type f -iname '*.map' -print0);
    local $/ = qq(\\n);
    #     CSV spec
    #     - record separator is CRLF
    #     - field separator is comma
    #     - every field is quoted
    #     - text encoding is UTF-8
    local $\\ = qq(\\015\\012);    # CRLF
    local $, = qq(,);            # COMMA
    # print column header row
    my @dd = ('column 1', 'column 2', 'column 3', 'column 4', 'column 5', 'column 6');
    print map { s/\"/\"\"/og; qq(\").$_.qq(\"); } @dd;
    # print data row per each file
    while (@ff) {
        my $f = shift @ff;    # file path

  • How can I use wget, cron and Automator to periodically pull a dynamic image from a URL to local storage, and then update a Keynote slide with that image, automatically?

    How can I use wget, cron and Automator to periodically pull an image from a URL (which is dynamically updated - like a weather map, say - to local storage, and then update a Keynote slide with that image, automatically?

    Any particular reason for those specific technologies?  wget does not exist on a mac, although you can nstall it I guess.  OS X has curl installed which should do pretty much anything you want to do with wget.  cron is being replaced by launchd, although cron still exists on mountain lion.
    As far as I can tell from automator all the standard 'actions' to access keynote  available to it require keynote to be open and running, but does not provide a function to actually open it.  So I think you will have to write some applescript, as a minimum to open and quit keynote. I notice that the keynote actions are mostly circa 2005 an wonder if they would even work.
    Under utilities in automator 'actions' there is a capability to add applescripts as part of the workflow.
    Also, note that cron is being dprecated by Apple and replaced by launchd.  that said cron is stil on my mountain lion instalation.
    This entry at stackoverflow shows use of cron with curl to get web urls.  http://stackoverflow.com/questions/1683620/getting-started-with-cronjobs-on-a-ma c
    If I have any time I may try and get this to work as it is quite interesting and new to me.  But otherwise, good luck.

  • How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes?

    How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes? I wanted my teenager's AppleID to be different from mine so that she couldn't charge stuff to my AppleID, therefore I created me another one. Now when I go to Sync either device, it tells me that this IOS device can only be synced with one AppleID. Then I get a message to erase it, not going to do that, lol. If I logout as one ID and login as the other, will it still retain all synced information on the PC from the first IOS device? If I can just log in out of the AppleID, then I have no problem doing that as long as the synced apps, music, etc stays there for both. I am not trying to copy from one to the other, just want to make sure I have a backup for the UhOh times. If logging in and out on the same PC of multiple AppleIDs is acceptible then I need to be able to authorize the PC for both devices. Thanks for the help. I am new to the iOS world.

    "Method Three
    Create a separate iTunes library for each device. Note:It is important that you make a new iTunes Library file. Do not justmake a copy of your existing iTunes Library file. If iTunes is open,quit it.
    This one may work. I searched and searched on the website for something like this, I guess I just didn't search correctly, lol. I will give this a try later. My daughter is not be back for a few weekends, therefore I will have to try the Method 3 when she comes back for the weekend again. "
    I forgot to mention that she has a PC at her house that she also syncs to. Would this cause a problem. I am already getting that pop up saying that the iPod is synced to another library (even though she is signed in with her Apple ID to iTunes) and gives the pop up to Cancel, Erase & Sync, or Transfer Purchases. My question arose because she clicked on "Erase & Sync" by mistake when she plugged the iPod to her PC the first time. When the iPod was purchased and setup, it was synced to my PC first. When she went home, she hooked it up to her PC and then she erased it by accident. I was able to restore all the missing stuff yesterday using my PC. However, even after doing that it still told me the next time I hooked it up last night that the iPod was currently synced with a different library. Hopefully, you can help me understand all this. She wants to sync her iPod and also backup her iPod at both places. Both PCs have been authorised. Thanks

    how can i use my account without the billing info, as i do not have a credit card. and my shipping and billing info is under US. i'm in singapore. how do i change this?

    If you are just visiting Singapore, then leave the account as it is. If you have moved there, then view your account using the iTunes app on a Mac or PC and change the country/region to your current location and address. If you do not have a bank card, you can fund your account using iTunes gift cards if available in Singapore.

  • How can i use microsoft word on ipad 2

    how can i use the microsoft application on my ipad 2?

    The Pages app is also compatible with MS Word. Unlike some of the others mentioned, the document is actually stored on the iPad as opposed to 'the clouds'. Again, most of those mentioned are cut down versions of MS Word.
    Stand back and look at this constructively; do you need to regularly access to the document from more than one computer/device without the need to keep amending your document on your computer and sending it to your iPad? If so, Documente to Go etc may be the best choice.

  • How can I use the credit on my account instead of credit card to buy apps?

    I have a gift card credit on my account but when I want to buy an app it takes me to my credit card details. How can I use my credit on my account instead of credit card?

    You shouldn't have to put in a credit card, no, but from time to time the iTunes Store seems for some reason to try to insist on one. If just confirming your mailing address doesn't stop it from complaining, go here:
    http://www.apple.com/support/itunes/contact/
    and follow the instructions to report the issue to the iTunes Store.

  • How can i use one SQL statement to solve problem?

    How can i use one SQL statement to solve the question below?
    For a Table named A, there is a column named F(char type).
    Now select all the records where F like '%00' and update their F value to '%01'
    Just one SQL statement.Do not use PL/SQL block.
    How to do that?
    Thanks.

    What is the data volume for this table?
    Do you expect lots of rows to have '%00' as their value?
    Following two statements come to mind. Other experts would be able to provide better alternatives:
    If you have index on SUBSTR(f, 2):
    UPDATE A
    SET    f = SUBSTR(f,
                      1,
                      length(f) - 2) || '01'
    WHERE  substr(f,
                  -2) = '00';If most of the rows have pattern '%00':
    UPDATE A
    SET    f = SUBSTR(f,
                      1,
                      length(f) - 2) ||
               DECODE(SUBSTR(f,
                             -2),
                      '00',
                      '01',
                      SUBSTR(f,
                             -2));

    It is not possible to create a new iCloud account using a Windows machine. You must create the account using a Mac (10.7.5 or more) or an IOS device (iPhone etc). Once that is done you can sign into and use the account on your Windows machine.
