I am trying to use the java.awt.datatransfer package to cut and paste JPEG or DIB(BMP) formatted images to the windows system clipboard. I have an image encoder that enables me to get the JPEG, DIB image as a byte[] and I set up my data flavor as type "image/jpeg" or "image/bmp". When I use the setContents() it appears to copy something over to the clipboard. In the clipboard viewer though, it says something is there but can't be displayed. When you open word or wordpad, you do not have the option to paste even though something is on the clipboard...

I know that you there are problems cutting and pasting Java Images (java.awt.image) but if I can encode it as a windows supported type image/bmp or image/jpeg, I would think that it should work...

Should I beable to cut and paste a bmp, or jpeg to the windows system clipboard?or is this still a bug waiting to be fixed?

thanks.

Hi.. all my tests with Clipboard
Contets returned null
excepted a simple text...
tried this with 1.2 and 1.3
All my reseaches showed me that no one is really able to say what is possible and what not.
This is a point really to look out for another programming language !
Some idiots told about things like moving Images (DIB) from and to java and MS- Applications.. but no one never answered to any requests i did...
Even the sun pages woudn´t give You an answer to that question...
I'm fed up with the clipboard, but if
You or someon else is able to show me a demo that cuts and pastes DIB-stuff to MS I will change my mind...
Good luck to your researches...
Jens
