I'm a beginner and I've never used XUL, I've downloaded XULRunner , Could anyone tell me how to start with it. all I need is to design a toolbar.

Read "Getting Started with XULRunner"

I wrote a small standalone XUL application : see http://plindenbaum.blogspot.com/2009/02/standalone-xul-application-translating.html
This application contains a toolbar.

About XAML.Forms Previewer in VS2015

In VS2015 U3 if I try to use XAM.Forms Previewer the interface is empty and have only the "Android Phone" message without my XAML user interface.
I tried to rebuild the solution but the preview still doesn't works!
Whats happened?
Thanks in advance.
To be honest, XAML Previewer still has alot of issues with Visual Studio 2015. I'm encountering the same problem and I just followed the steps from an official Xamarin blogpost. There are workarounds shared by other developers, but it didn't work for me. See link.
But, I'd suggest you try out Gorilla Player. It's an instant Xamarin Forms XAML Previewer. You can also simultaneously view the design without compiling.
Hope it helps!

Windows 8, Metro app: About dialog box guidelines or suggestions

Are About dialog boxes "dead" in Windows 8 Metro apps? I looked over quite a few apps and screenshots of apps in the Windows store, and did not find any "inspiration".
Is there any guidelines from Microsoft or any article that discusses this issue?
What do you think is the best way to show a dialog box/popup that shows the app name, version, author and a link to the app's home page?
I am thinking of a icon button in the bottom appbar, something like "About Appname", that opens a popup with this information. I am using C# and XAML.
You would place the About into the Settings pane via the Settings Charm using the Setting Contract. You can see the About in almost all of the apps in the Store today. Quick start on adding Settings can be found here: http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh872190.aspx
Guidelines for app settings here: http://msdn.microsoft.com/en-us/library/windows/apps/hh770544.aspx
Take a look here.
It lets you create dialogs/flyouts very easily from a UserControl. A few lines of boiler plate and you are done. Takes care of animation, UI management etc.

ExtJs UI Designer tool

Is there a designer tool for ExtJs or Eclipse plugin for it?
I'm developing an interface which is completely similar to desktop environment.

Now I'm modifying the above demo. But it is very hard and time consuming process.
Can somebody tell me about this?
Thank you!
There is Designer from Sencha: http://www.sencha.com/products/designer
Sencha Designer (Architect) should be your first choice. You can find it here. http://www.sencha.com/products/architect
however, if you just want to play around quickly here is another unofficial one for ExtJS - http://www.projectspace.nl/

Adding an item to the system context menu

How do you add an item to the system context menu? I would like to let my users be able to right click anywhere and launch this program. I cannot seem to find it documented anywhere either.
Thanks for your help!
I am coding in vb.net
What you're looking for is creating a Shell Extension Handler for Windows Explorer.

Unfortunately doing this in a .Net application is a bit of a problem due to the way in which the CLR is loaded for COM plug-in style extensions. Raymond did a great job of exploring this problem here
