Obviously, There are more module of features in my Windows Phone 8 app. Normally i will restrict the developer to communicate between module to module. Hence i prefer to use Launcher and Choosers to solve this big trouble. Obviously my custom Launcher/Chooser will have their own Show() method to call the particular module as like build in Chooser/Launcher Task.Show().
In above case i should know the important concepts to follow when i write my own Show() method. From my knowledge these is the very basic one which comes by default NavigationHandling. Anyone could you please assist me on this?. Any help much appreciated.
Unfortunately, you can't write custom launchers and choosers. You can use only those that come with operating systems.
However, if you want to communicate with other applications, you can do it directly using App to App communication or via file extensions. In the former case you are quite limited since you must know which application you will call and what parameters you will supply, while in the latter case you tell the OS which file you want to open. This will show you a screen with all applications that can open that file type.
Both methods are limited and it is a shame that we don't have better app2app sharing capability.

I'm trying to embed Windows-Sidebar-Widgets into my own .Net Application (WPF and C#), but I dont't realy know where to start. I googled a bit but only found SDK and tutorials for widget-development. I found that there is a small service in Windows, running the widgets. My thought was that I could perhaps fake this service and provide his functions whithin my programm, so that I can run and show the widgets.
Does anyone have some tips on how to do this? Or some experience in doing so? Perhaps there is even some kind of libary for that kind of stuff?
If this is not possible it is also an option to switch to an OpenSource widged-manager to use this widgeds, but this is only an emergency solution and the windows-gadgeds would be very appreciated.
Some information about my system:
I've written some kind of small windowmanager for childwindows in my application. And on the top of this I want to show the widgets in some kind of HostWindow.
Any hint will be appreciated.
P.S.: I would be willing to share the results if I (or we) get this working :-)
I've never seen a library for hosting gadgets, but since they are basically just websites you could use the MSHTML component to host any arbitrary gadget in theory.
This isn't to say it will be easy.
You'll need to extract a gadget to some temporary directory, spin up something hosting MSHTML (in WinForms WebBrowser would be convenient), navigate to the appropriate file in that temp directory (discovered by parsing gadget.xml), and shove something resembling the System object into the gadget.
As a starting point, inject some script that sets System = window.external; onload and WebBrowerser.ObjectForScripting = new FakeGadgetSystem().
FakeGadgetSystem will need [ComVisible(true)] and to implement a decent amount of stuff. I'd advise grabbing a widget or two to test with that mildly exercise the Gadget API, and then slowly implement the calls they make. It'll be a long haul for 100% compatibility with the official gadget hosting service.
I'm rebuilding an Embedded application:
Prebuild application Specifications:
Use : For dispaying the captured images/video from microscope image capturing device on windows based PC or Laptops.
Sepcifications: Prebuild on .NET plateform using VC++
Flaws : Lacks some specified features.
Current Requirement:
Want to rebuild that entire application using C# and add some additional client features.
My Questions:
Is it feasible to develop such application in C#.net?
If yeh,What kind of resources available in C# to develop desktop embedded application?
Any references which show any of such kind of application?
Your suggestions on building this kind of application.
P.S. It is essential to buid it on .NET platform.
I think by "Prebuild" you mean "Existing". Why do you want to rewrite the complete application? As you have stated that the application is written in C++.Net. You can easily add all the new functions in C# and use that code from your existing C++.Net code.
Note: I'm making this answer CW because the question is hard on the limit towards some close reasons. Everyone feel free to edit and extend it.
Is it feasible to develop such application in C#.net?
That's a tough one...from the top of my head I'd argue that it doesn't matter. If you know C#, then build it in C#, if the client wants it in C#, then build it in C#. You'll most likely have to use COM-Components or API-Invokes anyway to accomplish this.
If it is a TWAIN device, you might be better of to stick with VC++, I found TWAIN on .NET a real pain in the a** and have given up on such features. Same goes for WIA, but that might just be me.
If yes, what kind of resources available in C# to develop desktop embedded application?
I guess you mean a Widget? In that case I have no idea, I never really looked at that (at least not on Windows). But as far as I know widgets on Windows consist of a data-backend and a HTML/JavaScript-Frontend, so you'll most likely have to develop the two separately.
Any references which show any of such kind of application?
I guess any WIA/TWAIN application would be a reference, at least your description sounds so.
Your suggestions on building this kind of application.
See your first question.
I want to work on windows API. I have an interest in creating network application that can communicate with web as well. I haven't thought any application yet. But before doing all this . I want to know where to start with. What all I need to start reading.
I have created lot of database interactive applications with window forms. But would like to start with this.
If you want to use Windows API methods from .Net, you'll need to use PInvoke to call them. There's a site called pinvoke.net that has samples for how you call many of the APIs so if you know which API you want to call, that's usually the best place to start.
For your use case maybe you dont need API at all. You could use the FileSystemWatcher .net class to react on any changes in a log folder e.g. It reacts on modify/add/delete of files.
I know that you can create a separate console application, however, I am in the final stages of testing and my application does not have an interface. Is there a way to simply open a console and interact with that inside the desktop application? This would be in a test method. (I am using C#, in Visual Studio 2008).
Thanks,
badPanda
You might be able to do what you want using AllocConsole (creates a new console) or AttachConsole (attaches to an existing console), but I think there are some limitations to what you can do with them.
See here for the API documentation for AllocConsole and here's the PInvoke page.
Here's a list of lots of Console functions, might be something else useful there too.
This may or may not be helpful, but some of the same techniques of GUI testing can be applied to a console app too, of course.
Here is an article and example code in C# for a user interface test.
Or there are totally different tools/languages that can be used for UI testing, such as AutoIt v3, which is easy to learn and apply. AutoIt does have a DLL/COM control that you can access from your preferred programming language (but I haven't used it that way so I can't comment on how well it works).
Using ExternalInterface in AS3 is it possible to call OS (C#?) functions within XP?
Example: Set the desktop background to a image supplied by a flash app?
If it is possible would it be different calls when applied to different OS. And what about cross over the Mac?
Any information would be great
Thanks
If you're launching the swf from within a C# app, external interface will do just fine. Nothing will change on the flash side, but you'll need to go through a couple hoops to get it to work in C#. It's not as simple as AMF or External Interface to JS.
All the communications to C# get converted to XML describing the data, and you've gotta write XML to send back to flash. Other than that though, its relativly simple.
Here's some info on how to do it. The AS portion is Flash 8/AS2, but the C# portion should say the same.
When working with Flash from a webpage or as a desktop app, you are limited to a small security sandbox and you will not be able to make any relevant OS call. I thought that switching to AIR would give the developper more flexibility but it doesn't seem correct either. From "The Pros and Cons of Adobe Air":
AIR apps have
file access, clipboard access, support
multiple windows, support drag and
drop, and can trigger notifications
(toast in Windows). If you app needs
to interact with the desktop in other
ways, the chances are that AIR is not
suitable. For example, there is no
access to COM automation, and no way
to execute external applications. The
reason is to maintain cross-platform
compatibility. That's a worthy goal,
but it would be good to have a way out
of the sandbox. Unlike Java or .NET,
you cannot extend AIR with custom
native code libraries. Nor can you
call operating system APIs.
As Alex Jillard commented, if your swf is called inside a C# desktop application, you should be able to access more OS funcionalities although I'm not sure how.
You could use as already mentioned AIR. Another idea would be to use HippoHX (I haven't written this, the similarity with my username is just coincidence). It runs on top of the NekoVM and gives you unrestricted (so no limitations like in AIR ) access to the system.
