#3 - my solution requires that the SERVER creates the printing file...so, if you application is www.awesome-app.com, your application would send the data that needs to be printed to the server, the server responds with a unique print-id, and then your open a new browswer window to www.awesome-app.com/print.ashx?print-id=12345. The response is the PDF/HTML/XPS/whatever file that the user prints. In out-of-browser mode with no online connectivity, the only thing you can do is open a "Save As..." dialog and save the file to the users computer - the user would have to find it and open it after. There really is no good way to handle offline printing right now. #2 - if that's the case, then that's probably the way to go. --- This is a bit off topic...but here is my take on licensing: Yes, licensing is a real pain...it's always a compromise between pain-in-the-ass-ness and "trust". In your case, the user has to go online to get the application anyway...just have them enter their license key before the application lets them do the offline install. It is my belief that you should protect your application up to the point where someone has to obtain a cracked version to use it without purchasing it. Anything more is a waste of time, because your application WILL be cracked if it is worth cracking. Silverlight applications are especially easy to crack if they work offline. Anything less is bad too, because a lot of users, even business users, will just re-use a "legal" cd-key if they can, because for some reason that doesn't seem as "bad" as actually cracking a program. Our applications verify their licenses every 30 days. While the application is running, a background thread tries to contact our server and update the machine ID that it is installed on. If it can't contact our licensing server within 30 days, the user gets a 15 day warning. If it still hasn't checked its license, the application gets locked out until it can. If a new machine ID checks a license registration, the old machine ID gets added to the uninstall list. If the app is run on the old machine, the license verification check fails and the user gets an error message that the license was re-assigned to another machine. This takes care of 95% of our license re-allocation problems. The only problem is if they want to move their license BACK to the old machine...in which case they can call us :) Also, if our domain is no longer registered to us, the licensing system shuts off, so their apps still work if we go under :P That'

Thank you so much kubben. You reply has been very helpful and guiding. Kindest Regards:rose:

Thanks to your help I managed to reduce the time to 17 seconds. My UI freezes these 17 seconds when it adds the nodes between the BeginUpdate() and EndUpdate() calls. I discovered that adding the nodes to the TreeView can not be done except on the main thread, so I called a DoEvents() in the loop and the freeze is gone. I can't have gone this far without your help. I really appreciate it. Thanks again. Regards:rose:

Well. I guess I'd go for that if my time is cut short. Thanks for your time Dario. Regards:rose:

Sure! Whatever protection is out there to protect anything -even encryption for God's sake!- is not to prevent hacking/cracking the thing rather it's to make it much more difficult to break, thus narrowing the margin of financial loss. So I was just looking for suggestion of a convenient user friendly way to protect a video material -which can't have a serial number to check for validity:)-, making it a bit difficult for 99% of users to copy or abuse. The other 1% is inevitable EscapeKey wrote: if the video will eventually get displayed on a user screen, your user can capture every frame of your video and create a video out of the frames. This is still possible, but is much difficult with appropriate streaming and hardware acceleration. For example try to pause a video in Windows Media Player, then press PrintScreen button. In the image in the clipborad you will see the video area blank. I know there are ways to get around this, but it's a bit harder than just copy/paste my video files. My videos are educational tutorials in many topics -including programming of course-. The best practice I can think of is that it should be downloadable freely on a website, and viewed only on the appropriate user's machine. This would allow us to provide users with very low priced high quality lecture in many fields, depending on the wide distribution for reward. For example a video course in anatomy that would cost you at least 300$ to attend in a private center, would be available on the site for about 5$!! Even better you can watch that video on your machine overe and over again! but of course you shouldn't be able to copy it to another machine, you bought license only to view it on this one! Anyway, thank you for replying. I think I have to go for the solution I was thinking of in my original post. I just hope it would work! Regards:rose:

I tried putting javascript into it, but i couldnt. I guess that is why. :)

Look for 'people of the book' in thr index of a copy of the koran, it is the term used for these religions. As for infidels, the unbelievers, yes, it does advocate violebce. It also advocates cutting hands and feet from alternate side for people who 'disrupt' society, and cutting hands off thieves. (OK, US states also kill people for crimes, so we cant criticise Islam too much on this point) Truth is the subjection of reality to an individuals perception

We had an old Xerox mainframe in our Engineering School and each of the student operators (there were about a half dozen of us) had our own customized OS (with development tools) on mag tape reels (loaded from tape drive 2)...and a small piece of mag tape that we spliced together to form an endless loop that just fit around the empty reels of tape drive 1 (with a mag tape bootstrap program recorded on it)...we never had to rewind the boot loader because it was always positioned at the start after each boot up (no start of tape / end of tape markers). :-D ah, those were the days when 32K bytes of main memory was way more than we needed...

Hello It's free. Just download VPC SP1. It's not really un upgrade. Rather it's a program. There is another "not free" edition, but I still don't know the difference.:) Regards:rose:
