Clipboard?

Can anyone provide a link for a tutorial on how to use clipboard objects? I am trying to enable copy and paste functions in my application.
Thanks in advance,
AJ

import java.awt.datatransfer.*;
void setClipboardContents(String aString){
         StringSelection stringSelection=new StringSelection(aString);
         Clipboard clipboard=Toolkit.getDefaultToolkit().getSystemClipboard();
         clipboard.setContents(stringSelection,null);
     String getClipboardContents(){
         String result = "";
         Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
         Transferable contents = clipboard.getContents(null);
         boolean hasTransferableText=(contents!=null) &&
                contents.isDataFlavorSupported(DataFlavor.stringFlavor);
         if(hasTransferableText){
                try {
                  result=(String)contents.getTransferData(DataFlavor.stringFlavor);
                }     catch(Exception ex){}
         return result;

Copying text to the clipboard in AVDocDidOpen event handler causes Acrobat 9 to crash

I'm trying to copy the filename of a document to the clipboard in a plugin with my AVDocDidOpen event handler. It works for the first file opened; however when a second file is opened, Acrobat crashes. The description in the application event log is: "Faulting application acrobat.exe, version 9.1.0.163, faulting module gdi32.dll, version 5.1.2600.5698, fault address 0x000074cc."
I've confirmed that the specific WIN32 function that causes this to happen is SetClipboardData(CF_TEXT, hText); When that line is commented out and remaining code is left unchanged, Adobe doesn't crash.
Is there an SDK function that I should be using instead of WIN32's SetClipboardData()? Alternately, are there other SDK functions that I need to call be before or after I call SetClipboardData()

Leonard,
I tried it with both "DURING, HANDLER, END_HANDLER" and "try catch," as shown below. However, it doesn't crash in the event handler; it crashes later, so the HANDLER/catch block is never hit.
The string that's passed to SetClipboardData() is good, because I'm able to paste it into the filename text box of the print dialog when I try to create the "connector line" PDF. I also got rid of all the string manipulation and tried to pass a zero-length string to the clipboard but it still crashes.
Here's the code:
ACCB1 void ACCB2 CFkDisposition::myAVDocDidOpenCallback(AVDoc doc, Int32 error, void *clientData)
    PDDoc pdDoc = AVDocGetPDDoc(doc);
    char* pURL = ASFileGetURL(PDDocGetFile(annotDataRec->thePDDoc));
    if (pURL)    {
        if (strstr(pURL, "file://") && strstr(pURL, "Reviewed.pdf")) {
            // Opened from file system so copy filename to clipboard for connector line report
            char myURL[1000];
            strcpy(myURL, pURL);
            ASfree(pURL);    // Do this before we allocate a Windows handle just in case Windows messes with this pointer
            pURL = NULL;
            HGLOBAL hText = GlobalAlloc(GMEM_MOVEABLE, 1000);
            if (hText)    {
                try
                    // Skip path info and go right to filename
                    char *pText = (char *)GlobalLock(hText);
                    char *pWork = strrchr(myURL,'/');
                    if (pWork)    {
                        strcpy(pText, pWork+1);
                    } else {
                        strcpy(pText, myURL);
                    char *pEnd = pText + strlen(pText);    // Get null terminator address
                    // Replace "%20" in filename with " "
                    pWork = strstr(pText, "%20");
                    while (pWork)    {
                        *pWork = ' ';
                        memmove(pWork+1, pWork+3, (pEnd - (pWork+2)));
                        pWork = strstr(pText, "%20");
                    // Append a new file extension
                    pWork = strstr(pText, ".pdf");
                    *pWork = 0;    // truncate the string before ".pdf"
                    strcat(pWork,".Connectors.pdf");
                    GlobalUnlock(hText);     // Must do this BEFORE SetClipboardData()
                    // Write it to the clipboard
                    OpenClipboard(NULL);
                    EmptyClipboard();

Pasting Image from Mac clipboard to Java Based Application.

Hi,
I am working on "iMac 10.2.7". I need to paste an image from other
application using "Java version 1.4.1". I am trying to retrieve the image
from the system clipboard after it is copied from some other application. I
am pasting the code which illustrates my requirement. It works fine on
windows. But does not work on Mac.
On Mac it does not cross the supported data flavor check
(clipData.isDataFlavorSupported(DataFlavor.imageFlavor) where clipData is
the Transferable object). It seems Mac has some InputStream instead of Image
in the clipboard when some image is copied. I tried to read that InputStream
using ImageIO.read(java.io.InputStream). But that is also returning null.
Thanks

How to extract Slide data in 3rd part application from clipboard

I need to be able to copy/paste or drag/drop from PowerPoint into another application (C# WPF). In my OnDrop method the DragEventArgs Data has these formats:
        [0]   "Preferred DropEffect"   string
       [1]   "InShellDragLoop"   string
       [2]   "PowerPoint 12.0 Internal Slides"   string
       [3]   "ActiveClipBoard"   string
       [4]   "PowerPoint 14.0 Slides Package"   string
       [5]   "Embedded Object"   string
       [6]   "Link Source"   string
       [7]   "Object Descriptor"   string
       [8]   "Link Source Descriptor"   string
       [9]   "PNG"   string
       [10]   "JFIF"   string
       [11]   "GIF"   string
       [12]   "Bitmap"   string
       [13]   "System.Drawing.Bitmap"   string
       [14]   "System.Windows.Media.Imaging.BitmapSource"   string
       [15]   "EnhancedMetafile"   string
       [16]   "System.Drawing.Imaging.Metafile"   string
       [17]   "MetaFilePict"   string
       [18]   "PowerPoint 12.0 Internal Theme"   string
       [19]   "PowerPoint 12.0 Internal Color Scheme"   string
The "PowerPoint 14.0 Slides Package" is a byte array... can this be converted into Slides?
If not how would I go about getting high-resolution images + slide text from a drag/drop?
[Originally posted here: http://answers.microsoft.com/en-us/office/forum/office_2013_release-powerpoint/how-to-extract-slide-data-in-3rd-part-application/a0b5ed64-eb77-49bb-bf44-e0732e23a5eb]

What I'd like to do:
Open PowerPoint
In PPT open a presentation
In PPT select a slide
Drag it to my 3rd party WPF application
In the 3rd party WPF application drop handler get the slide data (text, background image, etc...).
When I do this I get the DragEventArgs Data (the clipboard data) and it has the 20 supported formats I listed in the 1st post. From these formats #4 seemed like it could have some useful info.
WPF
<Window x:Class="PowerPointDropSlide.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="LightBlue">
<TextBlock Text="Drop something here!"/>
</Grid>
</Window>
Handlers:
public void UIElement_OnDragOver(object sender, DragEventArgs e)
public void UIElement_OnDrop(object sender, DragEventArgs e)
string[] supportedFormats = e.Data.GetFormats();
object pptSlidesPackage = e.Data.GetData("PowerPoint 14.0 Slides Package");

Try to make everything Automatic

You can have a look at Rolf Kalbermatter's post here (give him stars) or, if you're using scripting, you can use the Application class Get Clipboard Image method.

Problem with Clipboard on iOS

Hello,
i have a problem with Clipboard on iOS. My test code:
var ts:String = "This is a test string for clipboard...";
Clipboard.generalClipboard.setData(ClipboardFormats.TEXT_FORMAT, ts);
This code is OK on Android or Windows. Test string is in clipboard and i can paste it on other app. But on iOS not. setData return true, but text is not in clipboard.
Any ideas?

Hi,
Looks like it's a bug with iOS AIR, could you please open a bug at bugbase.adobe.com

Label "Customer" shows in Activity Clipboard shows both Customer & Contact

In CRM 4.0 we were able to enhance this so contact record would show as 'contact' instead of 'customer' in the activity clipboard.
In 5.0 this seems harder to do. Have played with config & development but no luck so far.
Any thoughts on how to achieve? this is a B2B scenario.

How do I load a picture from the clipboard (either Windows clipboard or Labview clipboard) into image data that can then be processed in Labview?

I want to load a picture from the Windows clipboard (and if not possible, then from the Labview clipboard) into actual numerical image data so that it can be processed in lab view. When I'm at the main screen where I can add controls, I see a section of controls called "Vision" in the tool bar where all the different controls can can be added from. When I go to the control called "Image" and put that on my form, and then look at the flowchart/blockdiagram programing window to see what inputs and outputs it has, I only see one output, and no inputs. And when I right click on it, I see NO way to load an image into the Image control. PLEASE help me.
Message Edited by Ben321 on 11-09-2008 04:32 PM

Hi Ben,
National Instruments has an image processing software called Vision and although I am not completely sure, I think the controls that you found in the control pallet are used in conjunction with the software. Depending on what kind of image processing you want to conduct in LabVIEW, you might want to consider purchasing that product.
If cost is an issue, there are functions in LabVIEW which allows you to take in image files and process them. However, please keep in mind that the capabilities are limited.
Images should be loaded onto LabVIEW not via the clipboard but through loading it from folders or directories. (There might be a way to and so if you find a way please let me know! I would like to know myself =D) If you open the function pallet by right clicking on the block diagram, in the programming folder you should find a directory called "Graphic and Sound". There, you'll find functions in which allows you to process images.
In the "Graphic Type" directory there should be a function called Read JPEG file.vi. There are also others which allows you to read png and bmp files. Please note that there are functions which write as well. Set a file path on the block diagram and inside the "Grahic and Sound" there is a "Picture Function" directory and inside there, there should be a function called "Draw Flattened Pixmap.vi" That changes the image into a format where you can process on LabVIEW. Inside the "Picture Function" directory there are several functions which allows you to process the specified image. Play around with it and see how it goes. And don't forget to Write the file in the end to save any changes.
I hope this helps

JTable and clipboard...

Hi all!
I'm trying to copy data from JTable to system clipboard. Here's my code that is
supposed to do that except it doesn't work. Nothing happens. The system is
Windows, rigth click invokes menu with only one position - COPY, which is served
by a appopriate ActionListener. I want to copy entire table (all data):
private class NotEditableTable extends JTable
NotEditableTable(Object[][] data, Object[] columnNames)
super(data, columnNames);
setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
setCellSelectionEnabled(true);
getTableHeader().setReorderingAllowed(false);
NotEditableTableEngine nete = new NotEditableTableEngine();
this.addMouseListener(nete);
public boolean isCellEditable(int row, int column)
return false;
private class NotEditableTableEngine extends MouseAdapter implements ActionListener
public void mouseReleased(MouseEvent e)
if (e.isPopupTrigger())
JPopupMenu menu = new JPopupMenu();
JMenuItem menuitem = new JMenuItem(Lang.TABLE_COPY, new ImageIcon("res/Copy16.gif"));
menuitem.addActionListener(this);
menu.add(menuitem);
menu.show(NotEditableTable.this, e.getX(), e.getY());
public void actionPerformed(ActionEvent e)
TransferHandler th = new TransferHandler(null);
NotEditableTable.this.setTransferHandler(th);
Clipboard clip = NotEditableTable.this.getToolkit().getSystemClipboard();
th.exportToClipboard(NotEditableTable.this, clip, TransferHandler.COPY);
}

I also tried the code above with a simple JTextField, both with text selected and not.Did my sample code use the TransferHandler??? The simple way to do it for a JTextField would be
Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();
StringSelection testData = new StringSelection( textField.getText );
//StringSelection testData = new StringSelection( textField.getSelectedText );
c.setContents(testData, testData);
As for the table I said that the Ctrl-C KeyStroke will invoke the default Action to copy selected data from the JTable to the Clipboard. This can be tested manually by simply using Ctrl-C. If you want to invoke it in your program then you need to get the corresponding Action from the JTable and invoke the ActionPerformed method of the Action. You can try using the
getActionForKeyStroke(...) method of JComponent to get the Action.

HELP... Clipboard not working in CS6 on Mac

DESPERATELY NEED HELP.
Just upgraded to Creative Cloud CS6 Photoshop on my Xeon Mac Pro, 16 gigs ram, tons of disk space, Mac OS 10.7 and when I take a screenshot I can't import it to Photoshop.
I get the message that it could not import the clipboard because the file is not a TIFF.
WHAT? I have been using PS since it was in Beta and NEVER had this problem before. How do I fix it??
I'm desperate... I have work to do but I can't do it without importing screenshots from the clipboard. Reverting to CS3 isn't an option because I've upgraded to OS 10.7 and it no longer works. UGH...
Thanks to anyone who can help... or who can tell me how to get through directly to Adobe to get a fix.
Carol

It sounds like something is wrong in the application that put the data on the clipboard.
It is writing something that is supposed to be TIFF, but contains problems.
This is probably not something that Adobe can fix - since the Macintosh clipboard works for others, and Photoshop is just reporting an error in the data given to it by another application.

In iOS 7, my clipboard is not working properly.

When I try to paste anything in an app or message it brings up a previously copied message, not my most recent "copy". What is going on?

I have the same thing as well, since the beginning, my iPhone 5S brings back into the clipboard about the first thing I've ever copied on it (I think it was inside Safari, 23rd of September, the exotic word "muography"). Now, whenever I copy and paste something, everything is fine for a few minutes (sometimes even less), but after some time, when I paste the presumed clipboard content, this damned "muography" turns up instead, ever and ever again. No way out, no reboot helps, even not the upgrade from 7.0.1 to 7.0.2, did not yet try to restore and re-install from backup, as that takes half a day of trouble. I suspected 1Password for a while, which is able to "forget" clipboard content after a well-defined time, but whether 1Password is present or not, whether it is set to forget or not, nothing changes, "muography" comes back into the clipboard after some ten minutes at most.

CRASH "Not enough memory to create clipboard. This should never happen."

What the F???
SvK

i was talking to someone at frankfurt about this (possibly logic had crashed on something we were looking at - i don't remember) and they said error messages like that were for the developers. the fact you saw the error message yourself was in itself a bug.
i don't know for sure, but i think you are seeing some kind of bug relating to memory management. try deleting history and reorganizing memory if you get this error a lot.

PLEASE how can I copy someting to my clipboard and paste it to my homework paper??? I can't cut and past or copy/paste anything.

Just please help. I'm feeling kinda silly.

Hi Mommajj,
Have you tried the keyboard shortcuts?
* Copy: Ctrl+C
* Paste: Ctrl+V
You might also want to look at [http:// http://kb.mozillazine.org/Clipboard_not_working this article about the clipboard not working]. There may be some helpful information in there.
Hopefully this helps!
