How can I build my own search function for the webbrowser control, and if possible remove the built-in one (CTRL + F find function, that is)? Any help regarding this would be appreciated.
Edit - How would I search for text and select it? Pretty much like how the find dialog will find text and select it, I want to do that and I have messed with the document property of the page but I still can't get it to work. Any help?
That is the purpose of the WebBrowser control.
There are third party browser controls you can use instead:
GeckoFX
Mono.WebBrowser
Update (following comments):
You can capture the KeyPress events of the control to find out if ctrl+f was pressed, then use your own search algorithm on the document returned by the control.
I expect you should be able to do something similar with the third party controls as well.

We have automated a few test cases using the Ranorex automation framework for a Silverlight web application. These test cases involve clicking buttons in order to invoke certain messages on the screen. In order to grab the button on the screen, we first create an Ranorex button object and then point it to the appropriate element using Ranorexpath. Then, we use the RanorexButton.Click() event to click the button. However, this event is unreliable. It works sometimes and at other times the button is not clicked. When the button is not clicked, we have to run the test case again from the start. What are we doing wrong? If this is a known problem of ranorex, please suggest workarounds.
I was facing the same problem but I am able to resolve the problem by introducing a Validate.Exists(infoObject) just before the click. Please make sure that you pass infoObject of your button or any element in Validate.Exists API.
Example:
Validate.Exists(repo.MyApp.LoginBtnInfo);
var button = repo.MyApp.LoginBtn;
button.Click();

I haven't heard about such a problem with Ranorex yet, maybe this is just a timing issue.
You could add a Validate.Exists(yourButton) right before the click, this ensures that the click is performed after the button was successfully loaded.
If it is a WebElement you could also use the PerformClick() method instead of the normal Click() method.
There are also different methods which will ensure that the button is in the visible area and has focus, like the EnsureVisible() or the Focus() method.
You will find the available methods of the used adapter in the online API of Ranorex.
If the Button is not within the area you can see without scrolling, you can use a
var button = repo.Buttons.button1;
button.EnsureVisible();
button.Click();
In this way the button is forced to be watched.
It might as well be an issue with the xpath and element Id-s.
If you have changing element Id-s even when the page is navigated away from and moved back (for example we have this issue with SAP related components) you might need to make a more robust xPath path variable using regular expressions.
Try to find object and parts of the path that do not change (eg. "iFrame id="MainContent"" or "btn id="ID_XXXX_Search_Button"") - ofcourse this will only help if the issue is within this.
Ranorex Regular Expression info can be found here: http://www.ranorex.com/support/user-guide-20/ranorexpath.html#c3294
A quick example of what I'm talking about:
Let's say we have an input field that has a changing ID in it's name:
US_EL.ID_F2B49DB60EE1B68131BD662A21B3432B:V_MAIN._046A-r
And I know that the part in the Id that doesn't change is:
:V_MAIN._046A-r
I can create a path for this searching the element by the ending of the elements' id that doesn't change using regular expression:
/dom[#domain='test.example.com']//iframe[#'identifier']//iframe[#'identifier2']//input[#id**~'^**:V_MAIN._046A-r']
The bold part will specify to search for an input element with an Id that ends with ":V_MAIN._046A-r".
An issue that might arrise from this is if you have elements using partially the same names you might get multiple elements returned for the same path. So it's wise to add a few more certain points to the path (eg. "iframe[#'identifier2']") when this issue arrises.
I am doing a website using asp.net C# and I would like to popup a small window with information as soon as mouse hover a particular word. I know that I have to use jquery but I don't know exactly how to do it.
Any suggestions please?
There are many plugins out there that will help you achieve what you are looking for. However it is also very possible to implement this functionality yourself. I wouldn't be surprised either if some of the plugins you come across also use similar code.
The following is my attempt to demystify tooltip/popup plugin behaviour.
You could wrap the desired word in a <span> element and give it a .hover class.
<div>
This is some text with a <span class="hover">special</span>
word that has hovercraft capabilities.
</div>
Your jQuery (ver 1.7+) would look something like this :
$(".hover").on('mouseenter',function(){
// The popup must be shown here (mouse is over element).
}).on('mouseleave',function(){
// The popup must be hidden here (mouse has left element).
});
I should add here that I am using a great and yet sometimes forgotten capability of jQuery called "chaining". The on() function actually returns the object that it was attached to. In this case $(".hover") - so if I want to call another function on that object I can just add it as another function at the end. Another example of this would be :
$("#myElement").text("An error has occured!").css("color","#FF0000");
That line of code would also at the text to #myElement and also turn the colour red.
With regard to your actual popup - I would suggest two things :
Have an element at the bottom of your markup (written last so highest index - or manually set the highest z-index)
You could also have the popup in a hidden element right next to the element that is supposed to trigger the popup.
What you're after sounds like a 'tool tip'.
The solutions using jQuery are somewhat involved - so I'll just direct you to external resources.

I am writing a simple personal app that has a browser control and I want it to automatically "Refresh" gmail to check it more often than it does by default. There are monkey scripts that do this but I'm trying to add my personal style to it.
Anyhow, I've looked around and found everything but what I can do in csharp using the browser control.
I found this:
// Link the ID from the web form to the Button var
theButton = webBrowser_Gmail.Document.GetElementById("Refresh");
// Now do the actual click.
theButton.InvokeMember("click");
But it comes back with null in 'theButton' so it doesn't invoke anything.
Anyone have any suggestions?
It's been awhile since I've used JavaScript, but given the other answers and comments that there is no real ID associated with the element, could you do something like the following:
Search all Div's with an attribute of Role == 'Button' and an InnerHtml == 'Refresh'.
Once the correct InnerHtml is found, get the Element.
Invoke the click on the found Element.
Again, this may be blowing smoke, but thought I'd throw it out there.
edit: Just realized you are doing this with C# and a browser control; however, the concept would still be the same.
The best suggestion I could give you at this point involves an existing API that is used for .NET web browser based automation:
http://watin.org/
Since the div tag with the desired button really only seems to identify itself with the class name, you could use the Find.BySelector(“”) code included with the most recent version of watin.
Using webBrowser control in a winForm. but when the webpage is updated by Ajax or in a frame, I cannot use
webBrowser1.document.getElementById, etc. to find that htmlElement. The element also won't show in the View->Source code in IE.
The untimate purpose is to find that htmlElement and simulate a click or other function like
invokeMember("staff").
The WebBrowser's Document object does indeed represent a live view of the DOM so there may be some other reason that you're unable to find it. DOM updates will not however be represented in View -> Source. You should use IE8's developer tools which will show you a live view of the DOM and maybe you'll see something like an incorrect/duplicate ID or something.
I'm guessing you have already solved this problem on your own, but if you haven't, refer to my question here: WebBrowser Control and GetElement by ID
Essentially, if you do something to the WebBrowser control (ie, add some member to the DOM) it will do so asynchronously. That is, it does it on another thread, that way it avoids locking your calling thread when the WebBrowser is doing work. The problem is that if you programatically modify something with a command, you will have to wait till that command actually finishes loading its changes till you can work with the result of it.
Check my question there for a code example of what I was doing. I hope someone can find my previous trials useful.
We are using the WebBrowser control in c# winforms and need to be able to get information about the Url the cursor is positioned on.
So we have a web page in design mode, which has multiple urls, when the cursor is over one I would like to call a method which would return the id of the link.
Thanks
You can use the IHTMLCaret to get the cursor position from there using IMarkupPointer you can get the element in the current scope.
The webBrowser control has a Document property which has a Links collection. Each Link is an HTMLElement which has events you can tap into. Again, I'm not sure what you mean "cursor" because in the web world, unless if you're in a textbox, there really isn't a "cursor" (which is what I meant to ask in my comment) but you can tap into the MouseOver event and other stuff like that.
Example:
foreach (HtmlElement element in this.webBrowser1.Document.Links)
{
element.MouseOver += (o, ex) =>
{
Console.WriteLine(ex.ToElement.GetAttribute("HREF"));
};
}
This will print out the actual URL that the mouse is over.
You can have a look at this article - Hosting a web browser component in a C# winform - which explains several ways to perform that. or go directly to this one - Hosting a webpage inside a Windows Form - Basically what you need to do is handle the Click of the DOM object inside the COM WebBrowser of IE. You achieve this by handling the Js events inside your C# code.
I remember this kind of customization must be done using the AxSHDocVw.AxWebBrowser COM object instead of the System.Windows.Forms.WebBrowser Class from the newer versions of the .Net Framework.
I could send you more data about this, I did it some project, just give me time to find it ;). In the mean time try with those links.
