Hi, I tested the DragPictureDemo tutorial (http://java.sun.com/docs/books/tutorial/uiswing/dnd/intro.html#cut) on both Windows XP (32 bit) using JDK 6 and on Windows Vista (64 bit) using the Sun 64 bit JDK (version 6). The demo does not drop the images to an external application e.g. windows paint. I also tried dropping the images to Wordpad. In wordpad, I get a drop, however the "image" dropped into wordpad is just a black square. I have also been trying to write my own code that will drop an image from a Java Swing application to an external app on Vista 64 (e.g. paint), however it does not seem to work. Anyone else have a problem dropping images from a Swing app to a native app (e.g. paint)? Any info would be appreciated! Thanks.

Andrew, Thanks for the response. I don't think it's a sandbox issue. I copied the source code from the demo link I specified and compiled and ran it as a java application and had the same problem. My application is also run as a java app (not applet or web start) and has the same issue. Thanks. -Yugesh. "Andrew Thompson" <u32984@uwe> wrote in message news:71b51033bf430@uwe...

This project? <http://java.sun.com/docs/books/tutorial/uiswing/examples/zipfiles/dnd-DragPictureDemo2Project.zip Quote: My application is also run as a java app (not applet or web start) and has the same issue. That is odd. Since you confirmed the app. was trusted, I gave the classes in the archive (mentioned above) a quick run. I could (on the aforementioned machine) paste pictures into Paint Shop Pro 3.12 (an ancient version of a nice image editor) and could D'n'D (or paste) pictures with Open Office 2 (Draw/Calc or Writer). It got a little more interesting when I tried D'n'D to WordPad and confirmed your result of 'blank image' arriving. It got a little more interesting still when I discovered that I could see the images I had drag/dropped into OpenOffice, when copy/paste from OO into WordPad - as an actual image! So in the same WordPad document, I had a blank image D'n'D'd direct from DragPictureDemo2, beside a colored version that had come via OO. A little bit of hunting led me here.. <http://www.rockhoppertech.com/java-drag-and-drop-faq.html#nativeimages> Which leads me to think that whatever flavor these images are being served up to (MS) Windows programs, it is not bitmap. OO seems to handle whatever format the D'n'D offers - so does PSP.
