if there is any way to prevent my application from taking screen shot iam using this method
if this is correct?Code:If Clipboard.ContainsImage = True Then Clipboard.Clear()
and also what about screen capture application they take the screen shot without using clip board what is logic behind it and if there is any way to resolve it?
well most won't copy to clipboard as it's extremely slow and assumes you'll be "pasting" it somewhere at a later point.
most will take the screenshot and write it directly to the hard drive as an image file. you'd have to monitor a folder's contents to see if files are added or something to be able to detect it. and at that, you'd have to know where it's writing them to.
This is a very strange request. It sounds like you're either trying to workaround a malicious program or else circumvent a legitimate security program. Would you mind providing some more details of exactly why you need to do this?
actually i have a request from a photographer he want to show his images to user via internet and i have a proper idea to do so but he want prevent from taking screen shots of his images. but its very tough job please give me any idea
You're correct: it's a very tough job and, I'd imagine, actually impossible. If people want to put images on the web that they don't want others to copy they usually do one of two things:
1. Use a low res version.
2. Put a watermark on each image.
The first option is probably not a good idea as it will make the photos look poor, so the second option should be what you and they work out between you.
Even if you could create an app that would prevent people taking screenshots, that's only useful if the app is installed. If these images are on the web then how can you possibly stop everyone from taking screenshots on their own computers?
yes i also give him (photographer) this idea but he said pictures are very precious and those who want to copy them they can use them with watermark without any hesitation .Quote:

I would bet large sums of money that what you're asking for is simply impossible.
i agree - impossible - there are alot of methods that can be used to take a screenshot - if you make ways to circumvent the common ones this there will always be other ways to do it.
I would have said (prior to desktop composition (pre vista) and desktop composition emulation (ie. pre windows xp sp3)) you could have made movie clips from your pics shown them instead as very few apps (i don't know of any) that could screen shot them in win xp. - but am sure its impossible now

Have at look at this site which does exactly as said, adds an overlay to push people away from just copying the image. The quality and size are less and the overlay should annoy 95% of normal users enough to stop them printing their own wedding album :).
Will your application prevent a person from taking a picture of the computer screen with a camera as well?
yes what can i do with a camera its not possible to stop camera ok i leave itQuote:
