Is there any way to download Windows updates programmatically from within a C# application? I want to manage the installation of updates from within my application.
The Windows Update API is documented here. A quick stackoverflow search has convinced me that you can indeed use COM from C# so this should solve your problem.
I also have some sample code, not in C#, but it may give you a head start in understanding how the interfaces can be used.

I am having some issues installing IUIAutomation if anyone could head me in the correct direction would be greatly appreciated. I'm attempting to get tab information from Microsoft edge
I could be totally wrong, I just started working with UI Automation myself, but as far as I understood IUIAutomation is working with C++, whereas the managed UI Automation API is for usage with C#. I played a bit around with UI Automation in C#, but for some reason I don't know, I don't get all the events. This is because I'm going to look into IUIAutomation next.
If you'd like to use UI Automation with C# you have to add it (UIAutomationClient and UIAutomationTypes) as references in your Visual Studio project.
I hope my answer helps a bit.
Cheers!
If you're trying to access the "IUIAutomationElement" or similar declarations, you'll need to reference the COM version of the UIAutomationClient (v1.0). You can find it on the same Reference Manager window as the .NET Framework version (using VS2017), you just need to search under the COM section instead of the Assemblies section.
If you're just looking to access "AutomationElement", you should be ok using the .NET Framework version. I mainly try to use this one, unless I need to access the LegacyIAccessible values without using a wrapper.
Let me know if this doesn't help, or you need more info.
Does anybody of you guys have experiences with including a C#-based Console Application in a C#-based Universal Windows App?
The reason why I'm asking: I've an already exsisting Console Application developed by another developer. This Application includes a database with all the queries which I need for my App.
The problem: When I try to include the CA in my UWA project many commands like
private global::System.Runtime.InteropServices.HandleRef
throw new global::System.ApplicationException
don't get identified by VS2015.
Is there a way to let the UWA project identify CA commands? For example with adding an external CA-library or something like that.
Thank you!
You can't combine full .NET (console, winforms, WPF) assemblies with an UWP app, as they're different .NET frameworks. For more details, please read this reply. Part of the code is shareable in a Portable Class Library (PCL), but most likely not all of the code you've written.
Possible solutions:
Create an API (yourself or with the other developer) to expose the functionality needed over a (preferably) REST api.
Find a way to cheat the system. Example: launch a file (associated to the console application) with the Launcher api and output the results to a text file on disk, which you then read from your UWP app.
The first one is guaranteed to work. You might find a way to cheat the system for the second 'solution', but there's no guarantee that it won't break in the future when Windows 10 gets updated (experienced that myself for another 'hack' on the upgrade between Windows 8 and 8.1).
I'm trying to automate a hidden .NET application, with another .NET application (written in c#) using the easiest way possible. It's NOT for testing purposes, it's a way to fulfill the lack of scripting for this application.
I already tried white framework, but there is one major problems with it: the way it's working. It's slow and it's not working on hidden windows and controls (like the winAPI does). Whats more, when "clicking" white moves the mouse, brings it's targeted window to the front and so on.
I was also thinking about using a user32.dll wrapper, because the way it's handling it's target is what I need, but I've red it's not working with .NET applications. It also would be a problem working with it, because my targeted application got 5 button labeled "...", and would be really hard finding 2 of them I need. I also would like to use the controls .NET id (the name the developer gave to it's controls when designing the GUI).
BTW, my targeted application is MeGUI if that helps. We do a lot of video encoding and a tool like this would help us a lot. I need the MeGUI to be hidden, because I'm the only programmer, others using my tool shouldn't see what happens in the background, not to talk about the many windows popping all around.
You can add a reference to the exe from your project and then create an AppDomain to run its main method. From there, it should be possible to queue delegates to its main thread's loop. With a bit of reflection, you could have those delegates invoke the click events and whatnot directly.
I've never attempted this approach, but it should work.
You should try Stephens idea instead of scripting a hidden app. A .NET Windows Forms App (EXE) is still a .NET Assembly and that means you can use that the same way as a DLL, just add a reference and use the public classes.
If you still want to try some scripting, take a look on the "Microsoft UI Automation" API and the "System.Windows.Automation" namespace.

I've inherited a C# window's application that I'm not real crazy about. I've got a looming deadline and I'm scared to death that some of my changes might be having adverse effects on existing functionality.
I've got a hobbyist background to RoR and I'm fairly comfortable with testing in that framework (using both RSpec and Cucumber).
I love having test scripts that can be ran on a regular basis and I'm willing to spend my personal time developing those for this particular project. I purchased a book from PragProg.com on scripted GUI testing with Ruby (http://pragprog.com/titles/idgtr/scripted-gui-testing-with-ruby). So far, I'm digging what I'm seeing and I think that this should work well.
Unfortunately, I've got a fundamental lack of understanding concerning Windows app development. I'm making calles to FindWindowEx (via Win32API) to "attempt" to retrieve sub-controls in my application.
A big part of my confusion is how I should retrieve the Class Name of the control that I'm trying to capture. The example provided in the text is as follows:
edit = find_window_ex.call #main_window, 0, 'ATL:00434310', nil
Where #main_window is my application's main window handle, and 'ATL:...' is the class of a text box area. There is no explanation given as to how the author arrived at 'ATL:...'.
I've read some very old posts concerning MS's SPY++, but those seem to be obsolete (or for some reason it wasn't installed when I installed vs2010).
So, what's the best way for me to find control classes to be used with the findWindowEx call? I do have the source code - should I be pulling from there? What if I don't have the source code and I want to automate an application? Is there a utility that allows you to somehow "browse" controls on a running application?
Sorry for the length - thanks in advance for the help!

The best is for you to install the components so that you get Spy++, this is the best way I know of to get to the actual class names esp. if you do not have the source to the original controls, which might be from a library or possibly some standard ActiveX controls that Microsoft ships.
The ATL class name is probably for controls developed using Microsoft Active Template Library (ATL), this is a C++ template library which significantly simplifies the development of ActiveX controls, and COM objects etc. in C++.
I'm a beginner in programming. I've just made a program called "Guessing Game". And it seems to work fine. Can I integrate it into a website? The CMS that I'm using is Mambo.

additional info's
Thanks for all your suggestions.
I still don't have any background about Silverlight, WPF and Java Script which I think sounds good. I'm using Windows and I programmed my "Guessing Game" from Microsoft Visual Studio 2008 and it's using Window application forms.
Yes I guess, for the moment I let it be and start to learn Silverlight or Java Script so that I can integrate it on my website:-)
Thanks for all your input guys:-)
Cheers
A standalone executable cannot be directly integrated into a website. You have a few choices though:
Allow your users to download the executable and run it locally for themselves
Rewrite your program in JavaScript to have it run directly inside of an HTML page, though this could obviously involve a fair amount of reworking
Use Microsoft's Silverlight technology, which allows you to code in C# and produce a web-based frontend similar to Adobe Flash. Your program logic should remain the same and you should only have to change the UI code. In fact if you're already using WPF for the front end, the transition will be even easier.
There are several questions that you still need to answer.
What is your server running? If its not Windows, your exe will not run at all unless it is compatible with Mono or a similar framework for your server's operating system.
How does your "Guessing game" interact with the user? If it is through a WinForms GUI, it will you will not be able to use that GUI on the web. If your game is a WPF application your easiest route may be to port it to Silverlight and serve it up on a web page.
It is typically not trivial to make a regular windows application run in a web environment since on on the web you are really running in the browser, not on Windows.
Yes - in general, when you're talking about software, anything is possible. The question is, how difficult will it be?
To understand that, you have to give us more details about "Guessing Game" including how it is designed, what it's interfaces are, how readily extensible it is, and how prepared you are to change or extend it.
For example, if it is a Windows Forms GUI app, then it will be diifficult to integrate into a web app. If it is a console app, then it will be a little easier. If you can modify it to run as a Windows Service, then a little easier. If you can modify it to accept input from the network (as opposed to getting input solely from the keyboard + mouse), still easier.
You may be able to use reflection to load your assembly into the web application, but most likely, the answer is no.
Your best solution is probably to re-write the game in javascript.
The short answer to your question is now. I'm presuming that since you're running Mambo you're web environment is a LAMP stack. However, you're "Guessing Game" is most likely a Windows application from the sound of it. For a beginner in programming, there is no integration path you're going to be able to take that will allow you to have your game running on your website.
However, here are avenues you can take, which will require a significant amount of time to learn. I'm not saying you shouldn't take time to learn, by all means you should! I'm simply trying to illustrate the fact that this is not something that is going to be doable in a couple of hours.
Silverlight - allows you to run C# code with a WPF like interface on your client's browser and can integrate with your web site through javascript.
Let your client download it from your website and run it off of their PC. This would actually be fairly trivial and would be your quickest option, but it sounds like it's not the kind of integration you were looking for.
