You may think you've covered all the bases, but then all of a sudden there are 100 more bases to cover.

Screenshot capture

I have a question
Is there a way to write a code and apply it for every component at once.
I used the example from this link: https://aptframework.dev.java.net/gooey/screenCapture.html
public final class ScreenShot {
    /** The logger object for this class. */
    private static final Logger log = Logger.getLogger(ScreenShot.class);
    private static JFrame frame = (JFrame)XXX.getBeanFactory().getBean(XXX); //Parent's frame data
     * Empty Constructor
     * This allows the static local variable to be used in other classes
     * as their reference.
    private ScreenShot(){
        //Empty Constructor
     * Captures a screenshot by pressing a hotkey button
     * and, then it automatically saved to the specific
     * location path (i.e. C:/Screenshot folder)
    public static void captureScreenShot(KeyEvent kL){
        if (KeyEvent.getKeyText(kL.getKeyCode()).equals("F12")){
            /* File Unique Identifer:
             * Each screenshot's filename has its own unique identifer
             * to avoid being overwritten. (i.e. Screenshot1.jpg)
            int numFile = 0;
             * Check if the filename is existed.
             * If true - incrementing the numFile
            StringBuilder fileName = new StringBuilder();
            File f;
            do {
                 * Labeling the screenshot capture with a file name
                fileName.delete(0, fileName.length());
                fileName.append("Screenshot");
                fileName.append(numFile);
                fileName.append(".jpg");
                //Pathname location
                f = new File("C:/" + fileName.toString());
                ++numFile;
            } while (f.exists());
             * The image is being saved and adds to the pathname location.
            try {
                Robot robot = new Robot();
                BufferedImage image = robot.createScreenCapture(frame
                        .getBounds());
                String strFileName = fileName.toString();
                ImageIO.write(image, getImageExtName(strFileName), f);
            } catch (AWTException awtEx) {
                log.error("Failure: Unable to capture a screenshot of a window: \n"
                                + StackTraceString.asString(awtEx));
            } catch (IOException ioEx) {
                log.error("Failure: Unable to identify the screenshot's file extension: \n"
                                + StackTraceString.asString(ioEx));
     * Obtains the extension of a filename
     * Returns value of String
    protected static String getImageExtName(String fullFileName){
        if(fullFileName.endsWith(".jpg")){
            return "jpg";
        throw new IllegalArgumentException(fullFileName);
}Then I added this code to the parent that contains all components:
As a local static variable in the parent frame class-
     * KeyListener:
     * Listens to the buttons that are pressed on the keyboard.
     * If the "F12" button is being pressed, then it automatically
     * activates the performance of capturing the Screenshot.
    private static KeyListener keyStrokeListener = new KeyListener(){
        public void keyPressed(KeyEvent kE){
            ScreenShot.captureScreenShot(kE);
        public void keyReleased(KeyEvent kE){
            //Ignore - Required to include this to activate KeyListener()
        public void keyTyped(KeyEvent kE){
            //Ignore - Required to include this to activate KeyListener()
    };Inside the construct of the parent frame class:
    public ParentFrame(.................................) {
        super("Parent Frame Window");
        addKeyListener(keyStrokeListener);
    }It only works if the parent frame has the focus. If I open a child window from the menu in the parent window, then the child window get the focus and the Screenshot is not working at all unless I added to all components like this:
component.addKeyListener(keyStrokeListener);

you don't add the keybindings to the frame, instead add it to the rootPane (or layeredpane),
but I missed the 'child window' bit from your first post. In that case you're probably better off
using an awtEventListener.

A plug-in to prevent screen capture

Hello,
How can i write a plug-in that prevent screen capture.
thank you very much.

That's outside the scope of PDF and Acrobat - it's an OS-specific issue since the same question applies to if you had to write this as an application.
Keep in mind that you are not only trying to stop the OS-native capture (aka Print Screen) BUT also all the myriad of 3rd party capture tools.
Oh, and while you are at it - don't forget to prevent someone using their digital camera to take a picture of the monitor...

Prevent screen capture, copy and paste

Hi guys,
Can Java programming prevent screen capture? Is there any example that I can refer to?
By the way, is there any example codes on how to disable the function copy and paste, as well as Ctrl + N to open a new browser with the same URL.
Thanks

Thanks for the speedy reply.
I don't think the problem is the number of characters that
can appear in the tooltip, as I'm having no problem with putting in
as long a reference as I need. My problem is the actual cutting
from the RH "document". If I try to cut a relatively short piece of
text from RH, <100 characters say, and then paste it into word
(which I did to check that there wasn't any weird formatting), I
get a line break at between 80-90 characters and always on a
complete word, i.e. it doesn't break in the middle of the word.
I was hoping for some solution that would allow me to copy a
reference from one part of my RH file and then paste the whole
thing in to my tooltip, but if this is not solveable then I'll just
have to build in some extra time to my project.
Thanks again.

Paste clipboard screenshot capture into applet

hi,
im trying to find a way to paste a clipboard screenshot into a java applet. these are the steps:
1. user presses alt+prtscn
2. user copies screenshot capture into clipboard (control + c)
3. WHAT I NEED TO DO: take screenshot capture and paste it into the applet by pressing control + v.
im not sure how i make a placeholder for the image, if someone could explain that. also, after i put the image in the applet i would like to be able to save it in jpg/gif format.
if anyone can help me out, please do. i can be emailed/reached at "i aim robin" on aim or [email protected] to discuss.
thanks for your time.

I'm not sure if an unsigned applet can do this. To get the system clipboard containing the image, call Toolkit.getSystemClipboard(), but I'm not sure if applets are restricted from accessing it. If you can get it, you'll have to parse the bytes to create the image (unless you can find a third-party class to do it). In a Windows environment, the screenshot images are like 32-bit bitmaps with a shortened file header. Also, unsigned applets cannot save files, so they cannot create the jpg and gif files. I hope this helps at least some.

IRM preventing screenshots in SharePoint Online

Hello,
We have IRM subscribed and configured for our SharePoint Online site, and it seems to work swimmingly, however, I expected it to prevent a screenshot from being taken.
See:
https://support.office.com/en-us/article/Apply-Information-Rights-Management-to-a-list-or-library-3bdb5c4e-94fc-4741-b02f-4e7cc3c54aa1
===========
How IRM can help protect content
IRM helps to protect restricted content in the following ways:
Helps to prevent an authorized viewer from copying, modifying, printing, faxing, or copying and pasting the content for unauthorized use
Helps to prevent an authorized viewer from copying the content by using the Print Screen feature in Microsoft Windows
Helps to prevent an unauthorized viewer from viewing the content if it is sent in e-mail after it is downloaded from the server
Restricts access to content to a specified period of time, after which users must confirm their credentials and download the content again
Helps to enforce corporate policies that govern the use and dissemination of content within your organization
===========
It does not seem to prevent this...am I missing something obvious? Thank you!

My understanding is this is built into RMS/IRM and that there isn't any additional configuration. I have a couple of thoughts, let me know if these apply in your case.
1. Protecting against print screen only works with Windows print screen. 3rd party capture tools may bypass this and still allow a user to take a screenshot.
2. The application needs to be opened in an RMS-aware application (e.g. the Office Suite, Word, Excel, PowerPoint, etc).

Slightly OT: bios screenshot capture device

Somebody here (or perhaps on the Framers list) asked about techniques to get good bios screenshots. For those who might be interested, I just came across a good example of screens, and a mention of the video capture device used.
Image: http://www.hardocp.com/image.html?image=MTI5NDcxNTE1M1NNSTgwSDVodGFfM18yX2wuZ2lm
Tool:
Dan_D, forum editor, said:
"They are taken with an old school DVC-80 S-Video capture device using an S-Video output on an NVIDIA graphics card. The AMD / ATI's produce inferior results via S-Video so I never use those for screen shots."
http://hardforum.com/showthread.php?s=a8982caf7410523d9bd17933692b157f&t=1578842&page=2

I don't believe any Windows (or DOS) screen capture app can take a capture at the bios stage, no.
It would require a custom BIOS to do that, because all that is running is BIOS firmware during those screens.
However; historically, BIOS supported the [PrntScrn] key on the keyboard, and would dump a plain text copy of the current BIOS screen to the parallel (LPT) port.
What happens on machines lacking LPT is unknown to me. I have even less clue on what EFI and UEFI implementations do with PrntScrn, if anything.
The usual solution when you need an exact screen image is to use a digital camera.
Use a shutter speed of 1/30 second or slower, to avoid any screen refresh or black-screen-insertion artifacts.
Use whatever focal length provides the lowest pincushion or barrel distortion, usually telephoto.
Use a tripod. Be on-axis. Use the self-portrait timer if you don't have a cable release.
Set a custom white balance using an all-white screen.
Since BIOS displays are 640x480, any Mpixel count over 1Mp will do to avoid sampling artifacts when you crop, de-rotate, resize or otherwise morph the image to the final 640x480.

Neuratron's Photoscope prevents Paper Capture from working

I have been using Acrobat 9 Professional for some time without any problems. I installed Sibelius5 with Neuratron's Photoscope a few weeks ago and Paper Capture simply stopped working. I tried repairing the installation, and finally uninstalled Acrobat and re-installed it to no avail. I have spent literally hours trying to fix this problem.
I finally did a search here on the Acrobat forums and found the post: http://forums.adobe.com/message/1178373#1178373
I found a copy of the Paper Capture driver drs832.dll located here: C:\Program Files\Adobe\Acrobat 9.0\Acrobat\plug_ins\PaperCapture and copied over the ******* version that Photoscope dumped in C:\Windows\System32. Now my Acrobat Paper Capture applications work perfectly once more.
I just wanted to share and prevent anyone from going through what I've gone through.
Acrobat ERROR Message encountered:
"Acrobat could not access the recognition service because: Unable to locate the Paper Capture recognition service. Your installation may be corrupt. This is probably due to either a low memory situation or a corrupt installation. If the problem is not clears up by shutting down other applications and/or rebooting, then please re-install Acrobat.

Validation of SAP End to End process,screenshots capture

Mine is an automation SAP testing project using QTP 10.0
We are supposed to send validation to onsite guys.
We tried using HTML coding and also word document to capture the screenshots.
Size will be very big for word document and for HTML the location was the BITMAP of the screens are saved are not accessible by onsite folks.
Please help in finding the solution

Hi Vikrant,
Whenever you are integrating MDM with any SAP or NON-SAP system data flow takes place in the form of Files.
If the data format are in the MDM understandable format then the data exchange can take place smoothly even without the use of XI,however if you are exchanging data in formats like Idocs or Bdocs which are not understandable by MDM then XI comes in the picture for data conversion and data monitoring purposes.
If you data flow in the form of Idocs rae failing then you need to find the reason of failure by using Transactions to monitoring the status of the idocs for eg status 51 will point that there is a problem in the data.
In this way you can test the integration of the scenario using XI in place.
Note that creation of a master by entering into the ERP system like ECC is different than creaating the master through the form of an idoc.There are a lot of mandatory and optional like validations that may not be true in both the cases.
So the only way is by monitoring the idocs flow nad faliure in the ECC system or XI system.
Kindly refer the below thread:
Re: Idoc failure
Hope It Helped
Thanks & Regards

Video Screenshot Capture

I need to capture a frame (pressing a button on stage) of a
streming video coming from webcam in local system, and send this
image to a DB when user confirms.
How does AS do this?
Is it possible in AS2?
Thanks in advance!

Simply didn't know wether it was possible in AS2 and/or AS3,
and did not find a section for asking it once in spite of AS

Screenshot capture fail

I am facing a problem using the screen-capture option.
when I use cmdctrl+shift4 or 3 it actually makes the sound that it captured my screen but I can't find the captured file on my desktop.
I have also installed the "deeper" application and changed the path and set it to "my documents" instead of "desktop" but nothing happens either..!
I wish someone knows how to deal with that.
thank you!

Doesn't it save to the Clipboard?
Command-Shift-3/4 save to the Desktop.

Video screenshot capturing

Ever since I've gotten me a Mac I've been looking for an application that would be able to grab screen shots at even time intervals from a movie, and compile it all into one screenshot. I know that for Windows, Media Player Classic had the option to do so, but on the Mac I haven't found such app yet.
I did give Screen Grabber 2.0.2 a shot, but it's quiet limited to the formats it can open, and it seems that the app is no longer supported.

why not just a simple screencast instead?
several suggestions:

Surely you'd be able to just edit it in imovie or something?
