Call Html Function In Webbrowser?
Dec 15, 2009
I'm trying to select a button in a webbrowser on the website twitterfeed.com. My usual solution of finding the element and sending invokemember("click") doesn't seem to work for this particular page, and the button doesn't have an id. The button has the following code:
<a class="btn_1" href="#" onclick="document.forms[0].submit();return false;"> "Continue to Step 2" <span> </a>
I assume the .submit() is referring to an html function, so can I simply call that function from the webbrowser somehow?

I am generating a page of HTML dynamically, which I then display in a WebBrowser control. Is it possible to have a button in my HTML which, when clicked, will call a sub or function in my VB?

I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:
<script type="text/javascript">
function HelloWorld()
{
var yourName = $get('txtYourName').value;

I want to create an ExpressionTree where a Func(of Vector, Vector, Vector, Vector, Double, Double, Vektor) should be called. So I use
Expression.Call(Forces(0).Function.Method, {Vec1, Vec2, Vec3, Vec4, Double1, Double2})(Vec1-4, Double1-2 are declared as ParameterExpression and Forces(0).Function as Func(of Vector, Vector, Vector, Vector, Double, Double, Vector). But I get an AgrumentException, because Forces(0).Function.Method has seven Arguments. (System.Runtime.CompilerServices.Closure as seventh argument at Index 0).

How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?

I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript function.
In order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there. Here is what comes up in Reflector for the AddAttributesToRender function in RegularExpressionValidator:
[Code]...
Note: I tried to add the expando property before the parent class does to see if the code would check for its existence and skip it, but that just causes an exception.

I am using a Webbrowser control to sign into Hotmail. Then once it is signed in then I'll just use this navigate code to open the inbox: I think that the problem is that the actual inbox(mail window) is within an iframe. I have to figure out how to call within the iframe. If you can goto hotmail and sign in and you'll see once your in the inbox when you view source it isn't the inbox's source but then when you right click then goto this frame then view the source to the frame it is.

I'm loading HTML into the web browser control, and adding a bit of javascript that hightlights a section of html when the user clicks on the area, by changing the classname. If you know the FireBug addin for Firefox, it's very similar to that. But what I need to do after this, is take the HTML source, and find where they clicked. But when I get the DocumentText of the webbrowser control, it's the original source. Not the source with the added class name.
Is there a way to get the source code with the javascript generated html?

I'm currently creating a HTML editor using a WebBrowser control and using IHTMLDocument2, but I'm currently having a problem that when I insert a table the user is unable to resize the table columns by dragging the border.
I was wondering whether anyone had done anything similar using IHTMLDocument2 and how I would be able to allow for the user to resize the tables like that. Or if anyone knows any good HTML editors that are written in VB.Net and are open source, unfortunately this is a requirement as I have to do some custom stuff for my customer.
