I found a picture online: https://beta.techcrunch.com/wp-content/uploads/2010/07/q6uvf.jpg
and had an idea: I wanted to play around with DRM on .wmv and .wma files
I don't want to decrypt DRM content or strip DRM out of a file (because I don't have any files with that)
I want to encrypt a file create a license server, and then decrypt that using Windows Media Player (like that picture describes but with my own files and server)
I read on Wikipedia: https://en.wikipedia.org/wiki/Windows_Media_DRM
that I need Windows Media Rights Manager SDK to package content and create licenses
I found that some documentation on how to use that here: https://blogs.msdn.microsoft.com/mediasdkstuff/2008/09/26/wmrm-sdk-10-1-2-best-practice-sample-code/
but the page is disabled and IA doesn't have any snapshot of it
So does anyone have that SDK with some sample code (the language the sample code is in does not matter but C# would be nice)
Thanks for Anwsering and Best Regards
Story:
I have written a HTML Merge Compiler that can merge resource's/assets into one single HTML file (minify it to the max) and compiles Javascript with the google enclosure compiler. I have written this compiler to speed up loading and interpreting the code and to obfuscate the code to protect a little bit (script kiddie protection). Major reason was/is speed and to make it compact.
This is working OK with reliable results and i use this in PhoneGap applications/games. I have also written a javascript library that encapsulate all platforms that works with standard HTML/CSS without the need to change the code, it works also in the browser, with a touchscreen or without or on any device or operating system. Write once, publish many ;-). The idea around it is that is working always, always operate the same but can use device specific things when available but does never fail (when something is not there, for example a vibrate functionality).
Anyway, most frameworks (like PhoneGap) concentrate on Mobile Platforms but i want to port it also to desktop platforms like Windows, OSX and maybe Linux. For Windows I have wrote an Delphi Application that loads the HTML in a TEmbeddedWB object (is Internet Explorer actually) but the 'problem' is that it is only suitable to Windows and IE is not the fastest browser around, especially when it is embedded (do not why it is slower than the browser itself). For example, when i load the compiled code in Firefox and/or Google Chrome it is blazing fast (you do not notice it is javascript ;-)).
EDIT:
Pre release of IE10 for Windows 7 is just launched, installed it and lag is gone!

Introduction to my question:
I have tried XULRunner of Mozilla a long time ago but the first time was not a pleasure to me and also i tried it today again but can't get it to work. Get a parse error in the main xul file of the project, window is an undefined entity. ??? I create a sample project like: http://mdn.beonex.com/en/Getting_started_with_XULRunner.html
I do not know what to do about this error. Also i think documentation is not up-to-date? Most documentation is from around 2006.
The question, what i want to know:
Before i am going to waste my time (see also introduction), is it
possible to create frameless (full-screen) desktop executables with
use of XULRunner like with PhoneGap?
Is it possible to create cross-platform applications with XULRunner, i mean, does it really work seamless. Where can i find a ready-to-publish example of a XULRunner project and is it possible to load local HTML file(s) like in PhoneGap?
It is possible and allowed to access external resources?
Long story, but maybe there is somebody that have tried this before and can lead me to choose the right direction.
is it possible to create frameless (full-screen) desktop executables with use of XULRunner like with PhoneGap?
Yes. You use disablechrome attribute to remove the window frame and sizemode="maximized" to have it open full-screen. Alternatively you can use the full-screen API if you want your application to run in a normal window and only switch to full-screen mode on request.
Is it possible to create cross-platform applications with XULRunner
Yes. There are things like menus that work very differently on OS X but most of the time you don't need to care what operating system your application runs on (Windows, Linux and Mac OS X supported).
Where can i find a ready-to-publish example of a XULRunner project
See documentation for a XULRunner application example. For "ready-to-publish" you would need an installer which doesn't come with the platform.
is it possible to load local HTML file(s) like in PhoneGap?
Yes. The top-level window has to be XUL but you can use some very minimal code here - essentially a single <iframe flex="1"/> tag. You can load HTML pages into that frame then.
It is possible and allowed to access external resources?
Yes, XULRunner applications have full privileges and can access files on disk as well as web resources without any restrictions.
I recently discovered that the PDFs exported by the Fast Report's PDF export filter aren't displayed correctly in Mac OSX, iOS and Android devices.
Fast Report informed that their pdf implementation only support Windows and they can't say when the new implementation that they are working on will be available.
I also tried to use the Gnostice export filter, but their demo installer didn't work in Delphi XE and when I contacted them, they took 15 days to send me some attached dcus which also didn't work. So I'm searching for another option.
If you know or use a PDF export filter which works with Fast Report, please let me know.
November 2015: Fast Report now have PDF/A support, with this option enabled the PDFs are fine on all platforms.
October 2014 - Fast Report 5 still seems to generate "Windows-only" PDF. A production-ready solution for this problem would be a benefit for cross-platform developers, given that Fast Report is the report generator bundled with Delphi.
Here is a fresh example generated with the Fast Report 5 demo, displayed with Adobe Reader 11 on Android 4.4:
And on Windows:
Fast Report informed that their pdf implementation only support Windows and they can't say when the new implementation that they are working on will be available.
I'm not sure that should be taken literally, considering PDF is supposed to be a cross platform format. It more likely means they don't actually have the time, equipment or expertise to test with those platforms. The PDF export filter that I'm using is the one built into Fast Report! It surely has some bugs, but I managed to work around them. And I think that might also work for you: Start with a simple document that does export properly, start adding features until it brakes, then you know what brakes it and you'll know how to work around the problem.
From my experience, here's what got me into trouble:
Rounded corners in the PDF document didn't look like the ones in the Fast Report preview. My fix: Found a combination of settings that made the exported PDF look exactly like the preview document. For me rounded corners were just a cosmetic feature, and with cosmetics there's no "One Look"; The alternative worked just fine. This might actually be fixed in the most recent version, but I didn't bother changing the document to test.
Transparency issues and outline issues. When working with the Fast Report editor (and when looking at it's previews) it's easy to overlap objects. You don't see this because of the object opacity. When exporting to PDF overlapped objects somehow managed to "print" outlines, and it obviously looked ugly. My fix: pay closer attention to those objects, make sure they don't overlap or make sure they don't generate outlines if no outlines are supposed to be seen.
Also make sure you test using ADOBE Reader, on any of the given platforms. If it works with the Adobe reader but doesn't work with other readers, there might be a bug in the 3rd party reader!
Edit: Here (link) is a sample PDF document generated by my Fast Reports application. I have no idea what kinds of documents you generate, but in my book that's a mighty complex document. Notice the diagonal line that starts where the table data ends, notice the embedded images (bar code, stamp, signature).
I opened that document on the following mobile devices:
iPad, running iOS: The document renders 90% ok. Images are not rendered at all, but they're not important to my document (and that's very likely a problem with the iOS reader). All the fancy colored lines and rounded corners are properly rendered. Some text is not properly rendered, and I'm pretty sure that didn't render because the "box" that contains it is too small for the contents. That most likely happens because I didn't embed the TTF fonts into the PDF and the Apple font on iOS didn't perfectly match the Microsoft font that was used on Windows.
Samsung Galaxy S2, running Android 2.3: The document renders 100% correctly.
Samsung Something(??), running Windows Mobile 6.5 and the FoxReader: The document is totally gibberish: pictures showed up but the spacing between letters was messed so bad it's impossible to read. I blame the reader, it's not Acrobat and it probably wanted to be "smart". And it broke it's teeth in my text encoding, because my text is not English.
About the PDF format: A document is "PDF" if it conforms to the standard, here's some Wikipedia info on that. In theory a PDF document should render exactly the same way any way you look at it, but there are forces at play that might work against this:
Not all readers are "Adobe Acrobat". In theory they're all compatible, in practice they're most like not 100% compatible.
PDFs that don't embed fonts depend on the fonts available on the host system. If they're not the exact same fonts there's trouble ahead, because they might have slightly differing sizes. Since we're talking about PDF's that were generated on Windows and opened on iOS or Android, those are obviously different platforms and they're guaranteed to use different fonts (because fonts are licensed, and I doubt Microsoft will licence it's fonts to Apple. I also doubt Apple would want Microsoft fonts). One possible solution is embedding fonts, but that makes your PDF files significantly larger.
AFAIK you can export your Fast Report pages as metafiles (i.e. vectorial Windows format, which is in fact a raw serialization of GDI commands).
Then you could be able to render those metafiles into PDF using our Open Source SynPDF library. It works from Delphi 5 up to XE, is Unicode ready, can embed true type fonts, and even create PDF/A files.
It is also able to export metafiles included in reports as vectorial pictures (and not bitmaps), and could therefore highly increase the pdf quality and at the same time shrink its size.
See for instance how it can be used for QuickReport. A similar technical should be used with Fast Report.
The Gnostice support answered my e-mail which I reported that their trial installer didn't work and send me some tips about which could be the problem and I was able to install it.
The company I work for already bought me a license and I already replaced the Fast Report Export Filter, which was a task as simple as droping 2 components on the same Form as the frxReport Object and setting 2 or 3 properties.
Also, to export the report programatically was also 2 lines of code and the information was easily found in their FAQ.
In the end, based on the recomendations and after looking for other options just to find abandoned components which doesn't have any updates for years, the Gnostice eDocEngine was the best solution.
Just hope they make their installer a little more "Programmer Friendly" as if it had complained about the lack of Fast Report's units in the search path I would've been able to at least have an idea of what was going on, instead of just getting an error and blaming them for having a trial installer which didn't work.
After replacing the filter and generating the PDF's using the eDocEngine component, the PDFs now work the same in iOS, OSX and Android.
Here is my workaround solution. It's not an universal one, but helped me in my case.
The main idea: use in report font with small file size (I've found Arial-like font with cyrillic charset with size 57kb). So the exported files can be 100-200 kb.
Details is here:

I use wPDF from WPcubed components, it's really a great product, good value for money
You can always install one of the PDF printers. These are in fact PDF convertors that install as windows printer. They work from any application including FastReprt components - just print on them.
I would like to ask if the acrobat sdk allows me to create an application that is able to render a pdf document from inside my application, that is, without the user having to open the adobe application along, but just having to have it installed on the system. thanks
No, the Acrobat SDK is for use with Acrobat, as its name implies. What you need is the Adobe PDF Library (APDFL), which is sold and supported by Datalogics. There are also a number of other third party PDF SDKs, some of which are quite good and almost all are far less expensive. If you haven't already made a decision, I highly recommend you investigate them.
Yes
From What is the Acrobat Software Developer Kit? | Adobe Developer Connection:
You can also use IAC support to render a PDF file into an external application window instead of the Acrobat window.
So, you can render a PDF using the Acrobat SDK in a custom application without the user needing to open Acrobat but it does need to be installed on the system running the custom application.
Alternatives
The Adobe PDF Library is an alternative means of rendering PDFs in a custom application and with it you could do so without needing to install Acrobat on the computer running the custom application. But it's expensive, e.g. thousands of dollars (per year?). And it's print output doesn't exactly match Acrobat [emphasis mine]:
Improved print output to bring it closer to Acrobat
There are also many many other PDF libraries with which you could render a PDF in a custom application.
I have an app that I'm developing and the main screen is supposed to have a simple embedded browser frame on it that displays a single remote webpage. Can anyone provide me with the necessary code or a reference that will help me figure it out?
It depends on what OS version you are going to support. Since OS 5.0 RIM adds a new package net.rim.device.api.browser.field2 which simplifies things a lot. For both old API (pre 5) and newer there is a sample apps in the BB SDK that demonstrates embedded browser usage.
On my PC sample apps are in the following dirs:
C:\Program Files\Research In Motion\BlackBerry JDE 6.0.0\samples\com\rim\samples\device\browser\browserfield2demo - newer API
C:\Program Files\Research In Motion\BlackBerry JDE 6.0.0\samples\com\rim\samples\device\browser\browserfielddemo - old API
Also note that the sample for old API actually fails to open an HttpConnection. It results in white screen being displayed instead of page content, so feel free to fix the sample code to append the URL with a proper suffix (;device=true or ;interface=wifi). I assume you already know how to open HttpConnection on BB using different transports.
Yes can you please try this.
BrowserSession browserSession = Browser.getDefaultSession();
browserSession.displayPage("http://www.google.co");
browserSession.showBrowser();
