I have an Internet Explorer window open. The title of this window will always be "test123"
how do I save the source of the contents of the window as an HTML file?
Please note that the process should not be to open a URL and read the HTML into a variable. I absolutely HAVE TO do it the way I described since I need to login to a site to be able to view the HTML that I want to save.
**if it makes it easier to do this through my winform and putting a webbrowser control on it, that is fine as well.
You can attach to virtually any Windows app, using managed code and the UI Automation classes. Not a lot of people know about this stuff.
Microsoft shipped a class library and runtime that allows applications to automate other Windows on the system. You can do things like click buttons, read textboxes, activate menus, and so on. Here's a quick intro.
It should be relatively simple to attach to an IE Window, and then programmatically tickle the File...Save As... menu option.
I did this the other day for a Paint.NET app. It took much less time that I thought it would.
But I agree it's probably easier to use a WebBrowser control in a regular app, to programmatically retrieve content. You could also use the System.Net.WebClient class to do it, if you don't need to show the HTML content.
If you embed a WebBrowser control inside of your WinForm you can do this:
webBrowser1.Navigate("http://StackOverflow.com");
string pageHtml = webBrowser1.Document.GetElementsByTagName("html")[0].InnerHtml;
This will return all of the HTML in the page navigated to.

[edit] It is a requirement that the webpage spawn and open in IE and allow user manual interaction after the programmatic actions have completed.[/edit]
I've seen a lot of code examples online about opening webpages or filling in webpage textboxes and getting a return value without ever opening them visibly.
I would like to open a webpage in IE, fill in a few textbox buttons
and then click the submit button and view the results visibly.
I am able to do this with a dll called Selenium, but I do not want to use a 3rd party application and it seems that WebBrowser() should be able to do this?
I can post my failed code examples if that would help.
Thanks.
Maybe this qould fit better as a comment, but I don't have enoigh reputation.
Do you know how HTTP-Forms work?
It would probably be easier to send a HTTP-Request to the target of the form you want to fill, including the parameters you would like to fill into the form.
So you don't need any WebBrowser or similar, just a simple HttpWebRequest object, where you specity the target, the method (very likely POST) and the data you'd like to send.
You can use the webbrowser control in Winforms. It is possible to access every DOM object of the website using the control. No need to open the IE externally.
You just need to specify the webbrowser URL as your link.
Then, fill the textboxes with code,
BrowserID.Document.GetElementById("TextboxID").SetAttribute("Value", "NewVaue")
Also, you can click on the button using InvokeMember("click").
There are lots of stuff using WebBrowser. You can learn it here.
I haven't looked into it very much but am struggling to find relevant information on the topic. I basically want to create a browser that applies a filter to a webpage by changing colors in a webpage. My guess is that I will have to change the html once loaded or something, would this work? Do I have other options?
PS. I don't just want to make every color darker, I would more like to invert the colors.
Edit:
If any you were wondering, I am talking about the XAML browser component that can be used in a Windows Phone application.
I think the simplest way to do that is to inject some Javascript into your page once it has loaded.
To do that, you need to set the IsScriptEnabled to true on your WebBrowser control and then subscribe to the Navigated event.
When that event occurs you can inject some JS codeby using the WebBrowser.InvokeScript method.
Here is an example of JS code that darken the page : JavaScript: Invert color on all elements of a page
If you are talking about in a PC internet browser, you can find an add-on to execute Javascript automatically, such as Greasemonkey for Firefox. If you are talking about Windows Phone's Internet Explorer, I don't really know what you could do there, as I don't think they allow add-ons.
I am currently playing a little bit around with the development environment. At the moment I am writing a small app, which adresses a Webbrowser-Control.
Therefore I was looking for an opportunity, to show the URL-bar and maybe manipulating the URL via input of the user. Is this anyway possible, or not implemented for the webbrowser control?
Thanks in advance!
The WebBrowser control itself doesn't have a URL bar. It is simply a control that has the ability to display HTML and run Javascript. The easiest way way to simulate one would be to create a textbox. You can then use its Navigate method to load the webpage:
myWebBrowserControl.Navigate(myTextboxUrl.Text);
Alternatively, you can use the WebBrowserTask, but your app loses all control of the user's activities within this task.
I think it'd be easier to just launch the web browser task directly. Customizing the URL bar would probably require rolling your own.
Here's a related question about opening the browser: Open webbrowser with specific url in WP7
I' trying to use webbrowser to create a folder explorer and I have few problems that I could not find any answer on the web... so I’ll appreciate your answers:
Can someone please explain how can I create the Up button (going to parent folder)?
How can I the explorer bar (on the left) to favorites or search as in windows explorer?
How can I implement the undo functionality (undelete files and folders)
What I would do intercept calls to a url and inject the data from your application. That way you can write HTML and display whatever functionality you want.
This Code Project WebBrowser Control might be useful too. I wouldn't be surprised if it allows you to handle the button click events on the navigation bar.
What is the best way to display Flash content in a C# WinForms application? I would like to create a user control (similar to the current PictureBox) that will be able to display images and flash content.
It would be great to be able to load the flash content from a stream of sorts rather than a file on disk.
While I haven't used a flash object inside a windows form application myself, I do know that it's possible.
In Visual studio on your toolbox, choose to add a new component.
Then in the new window that appears choose the "COM Components" tab to get a list in which you can find the "Shockwave Flash Object"
Once added to the toolbox, simply use the control as you would use any other "standard" control from visual studio.
three simple commands are available to interact with the control:
AxShockwaveFlash1.Stop()
AxShockwaveFlash1.Movie = FilePath &
"\FileName.swf"
AxShockwaveFlash1.Play()
which, I think, are all self explanatory.
It would be great to be able to load
the flash content from a stream of
sorts rather than a file on disk.
I just saw you are also looking for a means to load the content from a stream,
and because I'm not really sure that is possible with the shockwave flash object I will give you another option (two actually).
the first is the one I would advise you to use only when necessary, as it uses the full blown "webbrowser component" (also available as an extra toolbox item), which is like trying to shoot a fly with a bazooka.
of course it will work, as the control will act as a real browser window (actually the internet explorer browser), but its not really meant to be used in the way you need it.
the second option is to use something I just discovered while looking for more information about playing flash content inside a windows form. F-IN-BOX is a commercial solution that will also play content from a given website URL. (The link provided will direct you to the .NET code you have to use).
Sven, you reached the same conclusion as I did: I found the Shockwave Flash Object, all be it from a slightly different route, but was stumped on how to load the files from somewhere other than file on disk/URL. The F-IN-BOX, although just a wrapper of the Shockwave Flash Object seems to provide much more functionality, which may just help me!
Shooting flys with bazookas may be fun, but an embeded web brower is not the path that I am looking for. :)
There was a link on Adobe's site that talked about "Embedding and Communicating with the Macromedia Flash Player in C# Windows Applications" but they seem to have removed it :(
