How to read screendump image from clipboard to a file

I am trying to build a program that runs minimized while other programs are being used at the same moment. At certain moments I want to make a screenshot and save that information to a image file on the harddisk.
I have now the "user32.dll" to work and generate a "printscreen" push button. Now I want to write the information on the clipboard to an image file.
How can I read the information on the clipboard and use it in a VI?
Thanks in advance.

If the screen you want to capture is a VI, you should use Invoke Node -> Get Panel Image, and Write BMP File.vi.
See attached VI.
If the screen isn't made in LabVIEW, and it's minimized, printscreen can't catch it.
To save the clipboard image to file, you can import the clipboard image into LabVIEW first
(use Image Toolbox: http://www.geocities.com/gzou999/imgtool.htm), and then Write BMP File.vi

    Thanks a lot!

    Hello Tao,
    The parameter
       icm/HTTP/file_access_<xx>
    may help you to access the pictures without any db-access.
    The following two links may help you to understand the other possibilities as well.
    The threads are covering BSP, but it should be useful for WebDynpro as well.

  • Without using webutil how to read an image from client or own system

    Hi,
    I am trying to read image from my own system.
    (if I click on button (browse) then it should open an dialog box then i can select image from it. then I press another button(save) it should be store in the database.)
    So, i want read image without using webutil package how to do it.
    If i want read image from client system please tell me how to do it.
    I am getting with webutil package but there is any other chance to get the image.

    Please keep in mind that Forms 10g is a release not a version.  Also, since you are running on Windows 7 64 bit - you should be using Forms 10g Release 2 (version 10.1.2.0.2) and a patchset to upgrade this to version 10.1.2.3.0.
    Now, to answer your question - I happen to agree with MarkReichman, WebUtil would be my preferred method, but since you don't want to use WebUtil then the only other way would be to use a 3rd party Java Bean.  I prefer WebUtil because it is supported by Oracle and I can contact them with any issues.

  • How do I get images from LR to windows file when it is saying they are offline or missing?

    I loaded pictures to LR where I made some changes. They were jpegs. I deleted some in LR that went to recycle bin. Originals were in a windows file 2009-11-08. Since I did not see the LR changes in the windows pictures I decided to transfer LR images to the original file and opted to overwrite originals, might be a fatal mistake as it turns out, I am new to this. So now the originals are missing from the windows file but the images are still in lightroom but I cannot do anything with them other than view them in the library or slide show. I would like to put them back in the windows file for uploading to my blog and I am really hoping they are not missing as it tells me in lightroom. Can't see why they are missing if I am viewing them. Did try suggestion from support about adding parent file, then right clicking and locate can't remember exact procedure but I couldn't get it to work. I need help?? Thanks.

    When exporting do not over write original files in the folder where your imported files are located. In fact I understood that LR had actually disabled this in more recent versions to prevent you doing exactly what you have done. So ensure you are running the latest version of the software (help, check for updates). over writing should only be done to folders of exported images (not those in the database). The whole point of LR is non destructive processing, that is your original files remain un changed by LR and changes are only applied to exported images.
    What you need to do now is not re import but synchronise the folder. Right click (cttr click) on the affected folder in Lightroom and select synchronise folder. Check all the boxes and go ahead. This will import your exported images..as you have over written your originals unless you have backed them up then they are gone. If the are backed up, then move them into the folder using the OS file browser before synchronising.

  • How to read a String from a simple text file.

    I have a set up popup reminders, the content of which I have entered into a text file. I read the text and display it in a specially formatted JFrame/JPanel.
    My question is, since readLine() has been deprecated, how do you read a simple line of text data from a file created by, say, notepad? I guess I could just use readLine() anyway, but I want to learn the language, and "playing by the rules" seems to be the way I should go.

    I''m guessing your referring to the readLine method of DataInputStream. Use another class, like BufferedReader, which also happens to have a method named readLine:
    BufferedReader in = new BufferedReader(new FileReader(filename));
    try {
        String line;
        while ((line = in.readLine()) != null) {
            //process line
    } finally {
        in.close();
    }

    Well I suppose the picture is stored in a blob. If that is so this is some code I have used to load a picture to a panel. Hope you find it usefull.
    PreparedStatement retreive = db.createPreparedStatement("select bl from test where ln = ?");
    Blob bl;
    try{
    retreive.setBigDecimal(1, new BigDecimal(jTFln.getText()));
    ResultSet rs = retreive.executeQuery();
    if (!rs.next())
    System.out.println("Empty Result Set");
    bl = rs.getBlob("bl");
    if (bl == null) {
    System.out.println("Null Blob");
    return;
    InputStream is = bl.getBinaryStream();
    int imageLength = (int) bl.length();
    System.out.println(imageLength);
    System.out.println(bl.length());
    byte[] imageData = new byte [imageLength];
    is.read(imageData, 0, imageLength);
    image1 = new ImageIcon(imageData);
    photo = new JPanel() {

  • How can I extract images from Numbers?

    Sounds a bit stupid but how do you extract images from Apples 'Numbers 3' on a Mac?  I have a client that sends images in XLS files, that normally in Word I would Alt Click and 'save as...'
    I was trying to stop using Word but this simple little feature will make all the difference.
    Can anyone point me in the right direction.
    Thanks,
    Dave

    Hi Wayne,
    Thank you for your response.  Sadly if you do this it copies in to the MACs clipboard as a snap shot of the image at the dimensions in Numbers.
    Eg. 
    An image I've extracted from the document via Excel saved out at it's original dimensions 1024 x 300px, even though it was placed, then scaled down to 300px wide on the sheet.
    Same image copied then pasted in to an image editor (as I couldn't paste into finder) was only 300px wide.
    The feature I need is to be able to save out the original image placed in the Numbers sheet.
    Anyone with ideas on this?

  • I'd like to save to file/database image from clipboard

    Hi, I've got following problem.
    In my swing application I would like to pase image from clipboard (f.ex. copied from msword). I use following code to do that:
    TransferHandler handler=jLabel.getTransferHandler();
    handler.importData(jLabel,clipData);
    Then I want to save image to database.
    I know it should look like this:
    ImageIO.write(RenderedImage im, String formatName, OutputStream output);
    But how to transform image from clipboard or graphics from jLabel1.getGraphics into RenderedImage ???
    thanx in advance !

    Starting with the original image I adjusted the levels (Image>Adjustments>Levels (Ctrl L) to the following settings:
    Then using the marquee tool I selected the areas not in use and filled with white:
    Till you get something like this:
    Then I used the brush tool to fill the other bits of the lines in white using these settings:
    Once you are happy with the result with a white background go to the Blending Options on your layer:
    and set the blend as below and press ok:
    This will make your layer look like its got a transparent background, then create a new transparent layer and place underneath:
    When you have done this combine the 2 layer by selecting both and then right click and merge layers:
    After these steps save as a .psd file then you can copy anything you need from this file.
    I hope this all makes sense and you get the result you want. Like I said fiddly! :-)
