I'm new to C# and I'm trying to do an application that automatize Internet Explorer.
When I click a button, the application does :
using ( var Browser = new IE())
{
Browser.GoTo("http://testweb.com");
Browser.TextField(Find.ByName("username")).TypeText("User");
Browser.TextField(Find.ByName("password")).TypeText("Pass");
}
But it doesn't write anything. It navigates to the web but...
Try this:
IE ie = null;
ie = new IE();
ie.GoTo("Link");
ie.WaitForComplete();
At least to get started.
For the other bit, you need to get an exact identification and then you can tell WaTiN to interact with it.
Textfield userTextBox = ie.Textfield(Find.ByName("name"));
userTextBox.TypeText("user");
This may seem banal but now you can add a peek definition in your code and see if "userTextBox" gets found by name. If it doesn't you need to find it through another method (ID or class).

I'm trying to connect to an Internet Explorer window that is already open. Once connected I need to send some keystrokes (via SendKeys) to the IE window for some processing. I've got the following code below that works up until the SendKeys command. It finds the IE window titled "Graphics Database". When it hits "SendKeys.Send("{TAB}");" I get the error "An unhandled exception of type 'System.NullReferenceException' occurred".
Additional information: I also get the following on the NullReferenceException error. The weird thing is if I code to open a new IE window and then use SendKeys it works fine. Connecting to an existing windows seems to cause this issue.
SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.
Can anyone please help me figure out what to do to fix this?

InternetExplorer IE = null;
// Get all browser objects
ShellWindows allBrowsers = new ShellWindows();
if (allBrowsers.Count == 0)
{
throw new Exception("Cannot find IE");
}
// Attach to IE program process
foreach (InternetExplorer browser in allBrowsers)
{
if (browser.LocationName == "Graphics Database")
{
MessageBox.Show ("Found IE browser '" + browser.LocationName + "'");
IE = (InternetExplorer)browser;
}
}
IE.Visible = true;
System.Threading.Thread.Sleep(2000);
SendKeys.Send("{TAB}");
SendKeys.Send("G1007");
SendKeys.Send("{ENTER}");
I was able to resolve this issue. I could never get the IE.Visible = true to work. This seemed to do nothing in my code. I had to use the SetForegroundWindow() to set the focus to the IE window.
// Find the IE window
int hWnd = FindWindow(null, "Graphics Database - Internet Explorer");
if (hWnd > 0) // The IE window was found.
{
// Bring the IE window to the front.
SetForegroundWindow(hWnd);
This site helped me immensely with getting the SetForegroundWindow() working.

Andy please bear with me as this will be long. First you are going to want to look mshtml documentation and Dom. https://msdn.microsoft.com/en-us/library/aa741314(v=vs.85).aspx I don't know why automation is so convoluted but it is. The UIautomation class works great for windows apps but has nothing really for IE that I've been able to find. Others will point to third parties like waitn and selenium. Waitn appears to no longer be supported and selenium won't let you grab an open IE browser. I have gone down this path recently because I wanted to be able to create an app to store my web passwords and auto fill them in since I can't save my username and passwords in browser due to security restrictions. I have an example here and hope it helps. First open up IE and navigate to http://aavtrain.com/index.asp. Then have a console project with mshtml referenced and shdocvw. Here is code below. It gets the window then finds elements for username, password, and submit. then populates the username and password and clicks the submit button. I don't have a login to this site so it won't log you in. I have been using it for my testing. Problem I have is sites with javascript login forms. If you get further with this info please post back as I am still trying to evolve the concepts and create something reusable.
SHDocVw.ShellWindows shellWindows = new SHDocVw.ShellWindows();
Console.WriteLine("Starting Search\n\n\n");
foreach (SHDocVw.InternetExplorer ie in shellWindows)
{
if (ie.LocationURL.Contains("aavtrain"))
{
Console.WriteLine(ie.LocationURL);
Console.WriteLine("\n\n\n\n");
Console.WriteLine("FOUND!\n");
mshtml.HTMLDocument document = ie.Document;
mshtml.IHTMLElementCollection elCol = document.getElementsByName("user_name");
mshtml.IHTMLElementCollection elCol2 = document.getElementsByName("password");
mshtml.IHTMLElementCollection elCol3 = document.getElementsByName("Submit");
Console.WriteLine("AutofillPassword");
foreach (mshtml.IHTMLInputElement i in elCol)
{
i.defaultValue = "John";
}
foreach (mshtml.IHTMLInputElement i in elCol2)
{
i.defaultValue = "Password";
}
Console.WriteLine("Will Click Button in 2 seconds");
Thread.Sleep(2000);
foreach (mshtml.HTMLInputButtonElement i in elCol3)
{
i.click();
}
}
}
Console.WriteLine("Finished");
Seems like I'm facing some sync issues in my code.
during my process, I'm clicking a button which opens a new window.
I'm swicthing to the new window by the following code.
_webdriver.SwitchTo().Window(_webdriver.WindowHandles.Last();
Then, I'm inserting data into fields within the next window.
problem is that sometimes the objects in the "next window" are not being found.
I'm getting : "can't find element" error.
for me it seems like a sync problem , meaning , DOM issues.
so I have tried using :
_webdriver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
and I even tried :
Thread.Sleep(3000);
Unfortunately , seems like most of the times the problem is that selenium didn't switch to the new window(could see it when debugging).
I'll be happy to have your assistance.
You could wait for two windows and then set the context to the new one:
var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(20));
// wait for 2 windows
ReadOnlyCollection<String> handles = null;
wait.Until((d) => (handles = driver.WindowHandles).Count > 1);
// set the context on the new window
driver.SwitchTo().Window(handles[handles.IndexOf(driver.CurrentWindowHandle) ^ 1]);
i am not sure how this is done in C# but i think selenium is same you just have to use C# syntax for loop.
//Switch to newly opened window (JAVA)
for(String winHandle : driver.getWindowHandles()){
driver.switchTo().window(winHandle);
}
this is how i do in Java. you will get driver.getWindowHandles() same method in C# as well, if i am not wrong as this is selenium method.
hope this is helpful to you.
I use watin, because I need to open some websites in the background for which the user needs to support Javascript. I don't know if WatiN is the best for this job, but at the moment it takes very long until Internet Explorer gets visible. I need to disable to popping up of Internet Explorer while using WatiN. User doesn't need to see the opening of sites. Is it possible while using WatiN to visit a website without showing it the user or should I use another alternative which supports JS on client side?
My code at the moment;
public static void visitURL()
{
IE iehandler = new IE("http://www.isjavascriptenabled.com");
if (iehandler.ContainsText("Yes"))
Console.WriteLine("js on");
else
Console.WriteLine("js off");
}
The WatIn.Core.IE class has a Visible property, you can initialize the object like that:
new WatiN.Core.IE() { Visible = true }
This way the IE will just blink on the screen when it's created, and then it will get hidden. You can later control the visibility of the IE with the ShowWindow method of WatiN.Core.IE class - I mean you can show it on the screen if you need, or you can hide again.
I use exactly that trick (of hiding IE) for writing UnitTests (using https://github.com/o2platform/FluentSharp_Fork.WatiN) that run in an hidden IE window
For example here is how I create a helper class (with an configurable hidden value)
public IE_TeamMentor(string webRoot, string path_XmlLibraries, Uri siteUri, bool startHidden)
{
this.ie = "Test_IE_TeamMentor".popupWindow(1000,700,startHidden).add_IE();
this.path_XmlLibraries = path_XmlLibraries;
this.webRoot = webRoot;
this.siteUri = siteUri;
}
which is then consumed by this test:
[Test] public void View_Markdown_Article__Edit__Save()
{
var article = tmProxy.editor_Assert() // assert the editor user (or the calls below will fail due to security demands)
.library_New_Article_New() // create new article
.assert_Not_Null();
var ieTeamMentor = this.new_IE_TeamMentor_Hidden();
var ie = ieTeamMentor.ie;
ieTeamMentor.login_Default_Admin_Account("/article/{0}".format(article.Metadata.Id)); // Login as admin and redirect to article page
var original_Content = ie.element("guidanceItem").innerText().assert_Not_Null(); // get reference to current content
ie.assert_Has_Link("Markdown Editor")
.link ("Markdown Editor").click(); // open markdown editor page
ie.wait_For_Element_InnerHtml("Content").assert_Not_Null()
.element ("Content").innerHtml()
.assert_Is(original_Content); // confirm content matches what was on the view page
var new_Content = "This is the new content of this article".add_5_RandomLetters(); // new 'test content'
ie.element("Content").to_Field().value(new_Content); // put new content in markdown editor
ie.button("Save").click(); // save
ie.wait_For_Element_InnerHtml("guidanceItem").assert_Not_Null()
.element ("guidanceItem").innerHtml()
.assert_Is("<P>{0}</P>".format(new_Content)); // confirm that 'test content' was saved ok (and was markdown transformed)
ieTeamMentor.close();
}
Here are a number of posts that might help you to understand how I use it:

var ie = new InternetExplorer { Visible = true };
ie.Navigate("http://google.com");
ie.DocumentComplete += IeDocumentComplete;
But when the document is opened, it's like a Ctrl+N in Internet Explorer.
I don't want to keep context and session. I would like a new instance of Internet explorer.
Can you help me please ?
Many Thanks
I think you need to capture the key board event and pass it to the InternetExpolorer control, if I am not wrong because the key interrupts are sent to your application (and not to your IE Control) it does not work.
http://msdn.microsoft.com/en-us/library/aa768335(VS.85).aspx
Hope that helps!!!
Based on your example code, I'm guessing your using the InternetExplorer class from ShDocVw.dll?
Instead of using that, try to open Internet Explorer by launching it as a new process...
System.Diagnostics.Process.Start("iexplore.exe http://www.google.com");
That may do it, but it may also be down to specific user settings in the browser itself.
I am using the following code (C#) based on the IWebBrowserApp com interface to find the Internet explorer window that matches the page I am trying to find, based on the title of the page.
I works fine if the page is on the first tab, but it does not work if its a later tab. So how do I get access to the tabs in internet explorer?
objSW = new ShellWindows();
IEnumerator ie = objSW.GetEnumerator();
while (ie.MoveNext())
{
obj = ie.Current;
app = (IWebBrowserApp)ie.Current;
System.Object docObj = app.Document;
HTMLDocumentClass hdoc = (HTMLDocumentClass)docObj;
if (hdoc.title.Contains(title)) matches.Add(app.HWND, app);
//do something
}
Sorry, but there's no supported API for tab enumeration/manipulation in IE9 or earlier.
