I am creating a web browser and every time i visit a certain site (yahoo), i get an error saying that javascript needs to be enabled.
Here is the exact wording: "This page requires that you have Javascript enabled on your browser. If you're not sure how to do this, click here."
How to disable the error, enable javascript.
I'm making a Windows Forms Application and in it I've placed a WebBrowser. When I try going to my homepage though, it says that JavaScript is not enabled. My question is, is it possible to import JavaScript? If so, how can I go about doing so?

I am *VERY* new to web-scraping and am trying to scrape some information off of a webpage that is heavily javascript enabled. An example of the page I am trying to scrape from is: [URL] I am trying to scrape the property links such as "322 E 98th St" The text appears on the webpage and I can find the link myself, but it doesn't appear in the page source code.
I am trying to scrape it using the webbrowser control using the WebBrowser1.DocumentText property, but it doesn't even show the links simply when I view the source in ie. I am sure this has something to do with the javascript it uses to load up the page or maybe iFrames,
Okay sorry to post another simple question but I was browsing through the web trying to learn how to stop a javascript error dialog from appearing on my program and I came across this code on the MSDN website. Me being the idiot, posted the code straight into my code which did not work.

when i go to the address ex http:address with a web browser (e.x. firefox), immediately a popup window appears asking for user name and password. I know both so i enter them.Then firefox allows me to see the web page.Now, in this page there is a javascript button called "Open", (and as i can see from the source code of the page, the button is calling a function called "open()") .
I need to make a web browser that can do all the above automatically and then it "presses" the button "open".
I can make a web browser and then add a button that 1)connects to the adress but how to 2)send the user name and password info and then 3) execute javascript to "press" the "open" button?

I'm having some issues finding examples of how to use the Awesomium web browser control in vb.net with objectforscripting. I know that objectforscripting isn't the same for the webcontrol used with awesomium since its HTML5 and not the traditional IE control that comes with vs 2010. The issue I'm having is finding any info/examples on how to communicate with the awesomium web browser control with my javascript. It's quite easy with the IE built in control with objectforscripting. I've found samples of how to do it in C# but I don't see any info of how I could do it just in VB. I've searched several things in google and I just can't seem to find anything on how to do it.So for example, I would have a button in a php page that the webcontrol browsers to and if I click the button it closes the application down. So I need to communicate using window.external with the webcontrol in VB.

I am needing to get the browser height and width of the browser window with vb. I can get these values by setting an ASP.Net hidden input control using javascript, after the page has loaded and a post back is done. I need to be able to get these values when the page initially loads so I can create an image based on those values.

I have a page in which one chooses from a selection of dynamically generated buttons. The ASPX code is as follows:
<div>
<asp:Repeater ID="rptrHalls" runat="server" OnItemCommand="Choose_Hall">
<ItemTemplate>
<asp:Button ID="btnChooseHall" runat="server"
[code]....
When I first tried running the code I received an error message of "Invalid postback/callback argument". I set the ASPX page to have a enableEventValidation="false" property and tried running it again. It generates the page fine but when I click on a dynamically generated button it acts as if it is loading something and then just brings me back to select_hall.aspx (the page all this code is one), when (as you can see above) it should take me to select_room.aspx.

I have a DataGridView that is bound to a list of objects called "BaseChange". The BaseChange objects are made up of 4 properties...
ChangeType
ChangeStatus
ChangeDescription
LastChangeDate
The datagridview has columns for all 4 values as well as a 5th (a checkbox column called "colIsSelected"). There is no problem binding the list to the grid and displaying the items. The problem is that the query that gets the selected items in the grid is giving me an implicit cast error when option strict is enabled.
This is the query...
Dim _changes As List(Of BaseChange)
_changes = (From _row As DataGridViewRow In dgvChanges.Rows() _
Where Convert.ToBoolean(_row.Cells(NAME_COLUMN_IS_SELECTED).Value) = True _
Select DirectCast(_row.DataBoundItem, BaseChange)).ToList()
...and it produces the correct results with option strict off. The implicit cast squiggle is on the "row As DataGridViewRow" code, and the full message is "Implicit conversion from 'Object' to 'System.Windows.Forms.DataGridViewRow'*".
If I exclude the "As DataGridViewRow" from the query, I get a late binding error on the _row.Cells and _row.DataBoundItem and this also fails option strict.I need this to work with Option Strict enabled, and in VB.
When using Nero Recode I get a error message shortly into the program saying:
"An unhandled win32 exception occured in Recode.exe [5580]. Just-in-time debugging this exception failed with the following error: No installed debugger has Just-in-time debugging enabled. In Vision Studio, Just-in-time debugging can be enabled from Tools/options/Debugging/Just-in-time"
As far as i can see it is enabled but I still i get this error message.
As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

I am making a configuration screen so that an administrator can easily determine what controls on a form are enabled according to a combo selection.
I have created a table (SQL2008 DB) to store the settings and need ideas how I can best implement.
The session form will start up normal with only a few controls enabled to start, but then when the user selects a "session type" from a drop down combo then the form will be configured for that type. Because there may be several different combinations, and I do want to offer the user the ability to add and configure more types as needed I feel like this may be the best method instead of hard coding.
Table Structure
SessionType varchar(25) not null PK
ControlSwitch varchar(50) Not Null
(Edit: I may add an additional DB field so that I can specify the default value of a control also)
Now what I thought I would do on the config form is have a series of combo boxes and the label represent each control with a value of True or False, then when saved it builds a string like example 1,1,0,1,0,1,1,1 or True, True, False etc.
The string would represent
ctrl1=on, ctrl2=on,ctrl3=off,ctrl4=on,ctrl5=off,ctrl6=on,ctrl7=on,ctrl8=on and so on.
