I am trying to search a page for certain links only, but can't seem to find a way to have it 'search' for a 'keyword' in the links, and only list those in a ListBox - What I have now works to grab ALL the links on the page, but I need to only find SPECIFIC ones:
Public Class Form1

ByVal e As System.EventArgs) Handles Button1.Click

I have two web browser controls on my form. I also have several buttons like bold, underline, etc. My probem is the gotfocus of the web control is not working correctly. If I click on the web browser control to add text the gotfocus is not fired. If I click on a text box first and then click in the browser control it is fired. I need to know which has focused so the bold etc know which control to work on.

So, I'm trying to make a spiffy little program that lets you search for flash games, and it will automatically display the flash game within the program. (by writing document text to a webbrowser control) Unfortunately, the site I use to get the games from uses iFrames from Custom Google Search to house the search results. I know how to deal with frames in a webbrowser (WebBrowser1.document.window.frames("frame name here").document.so on and so forth), however it seems as though iFrames are different. When I try
WebBrowser1.document.window.frames("googleSearchFrame")
, it doesn't recognize that it's there. Same thing if I replace the name with the index of the frame - it's not there. Using

I have a pretty good understanding of VB.NET. Basically I'm trying to fill in the password to login to a school website, but for some reason it won't fill the value in. The closest that I've come is getting the password to appear on screen, but it's not masked with asterisks and when I click login it says invalid password. It's almost as if it edits the label right before the text box for the password.
Here's a section of the html code from the login page:
HTML
<FORM ACTION="/pls/PROD/twbkwbis.P_ValLogin" METHOD="POST" NAME="loginform" AUTOCOMPLETE="OFF">
<TABLE CLASS="dataentrytable" SUMMARY="This data entry table is used to format the user login fields">
<TR>
<TD CLASS="delabel" scope="row" ><LABEL for=UserID><SPAN class=fieldlabeltext>UID:</SPAN></LABEL></TD>
[Code] .....
The textbox that has the NAME="PIN" is the value I wish to change. Here is some of the code that I have tried where webMain is a WebBrowser VB.NET control. This doesn't work, but does display the unmasked password:
Dim passwordTextBox As HtmlElement = webMain.Document.GetElementById("PIN")
passwordTextBox.InnerText = txtWingsPIN.Text
The webpage [URL]

I am writing a program which allows me to log in to my favorite forum, and displays me my fav. threads, and automatically refreshes current thread every 30 seconds or so.For this, I first need to login to the forum page. Fortunately, the forum allows to login during posting a new message, and it's a public forum so browsing threads is possible without login. Therefore I can directly jump to the "edit article" page without login, fill in login information and write the post, and then send it altogether. Here is an example link for that:

Here comes my problem. I have searched for autofilling values and my code is like this:
Dim mydoc As HtmlDocument = sender.Document
Dim mynickname As HtmlElementCollection = mydoc.Forms("f").GetElementsByTagName("input").GetElementsByName("nickname")
Dim mypass As HtmlElementCollection = mydoc.Forms("f").GetElementsByTagName("input").GetElementsByName("pass")
If mypass.Count > 0 Then

I guess it doesn't set the value attribute, at least during debugging the 'outerHTML' property stays like this:
"<INPUT class=form_input type=password value="" name=pass>"

I have a VB.NET application and a timer that refreshes the webbrowser every 5 seconds on the application. Now it works 100% fine with Windows Vista. It also works fine on another computer that has Windows XP. But when i come to run this application on my server that has Windows XP installed the application will just not refresh. Is there anything that i can do to code it to FORCE refresh the browser every 5 seconds?

I'm attempting to load a website, look through the HTML, and then put it into a control.When I do this, the site redirects to another page. I know how to pull the info, so I need to figure out how to get to my destination page. I'll break it down in steps:
1. Attempt to load www.site.com/1
2. If cookie is not on machine, site redirects to www.site.com/zip code.
2b. Enter Zip code
3. Attempt to load destination site again.
4. Page redirects to www.site.com/default.aspx
5. Attempt to load www.site.com/1
6. Success
If the cookie is already on the machine, it skips to step 3. No matter what, it always loads the default.aspx page first. This isn't a webbrowser control issue, it's a site issue. This happens when on a normal browser.I'd hate to say it's bad coding standards just because it's not working because I want it to, but it sure seems like bad coding standards.

I know this sounds like a simple thing but I have searched and all examples have not helped. I have been unable to update the textarea at I have gotten the code to work at other sites though.So specifically I want to update the "post a new thread" textarea. If you go toand then signup (you need an account to post a new thread). Then go to any forum and click "NewThread".I then can update the subject field but the textarea (name="message") does not update with the value. I am not sure why it doesn't work when I have got this working on a lot of other sites.

I looked all over the forum posts here and didn't see the answer to a question concerning iframes within the webbrowser control (there were similar issues however). The forum has a classifieds section that allows members to post threads daily. I have a message that I like to send once every day to a forum and decided that it would be best to achieve this programmatically. However, I noticed in the visual basic 2008 webbrowser control, that it doesn't seem to automate the iFrames within the browser using the htmlelementcollection codes.

I have created a VB.NET project that includes WebBrowser control. The web browser control navigates to html page that embedes a flash movie. Everything works fine except that when I want to exit the fullscreen mode of the video by pressing (Esc) key, it doesn't exit. If I view the html page with any other browser (Internet Explorer, Firefox, ...) it works perfectly. You can download the project from the link below. The files are in the Debug folder.

I'm having an issue trying to pull information from a specific website. I've asked about this once before, but had no luck through searches or responses.In a nut shell, the issue I'm having is trying to pull information from several URLs from a site.When I load the first URL and pull the information, it works just fine. But if I want to pull another from that same site, it acts like it is loading, but doesn't pull the information. In order for me to gather that information, I have to restart the program, but that beats the purpose.So, I wanted to see if the issue was related to cookies or something else the webbrowser control creates when loading a site. If this is the case, I'd like to clear out this information, or at least try it, after each time it pulls the information from the site.

I am loading a word document into the web browser control using code like this:
WebBrowser1.Navigate("C:DocsTest DocumentsTest.doc") When I do this, everything works fine and the user can use all of the toolbars.
However, if after I do that, I then open word outside of my app, all of the toolbars in the word document in my app become disabled.
I have done some searching and found other people have had this issue and this MS article mentions similar symptoms, but offers no solution.

Have experience with web scripting languages and SQL but am still getting used to VB.Currently using VS2008 to create a simple app in VB 2008 that uses a WebBrowser control. The user navigates to a web page, hits a button, and then every minute the web browser automatically refreshes, gets the page length, and alerts if the page length has changed by more than 100 chars.Unfortunately, I am noticing that VB uses the cached version of the page when it refreshes (I am using WebBrowser.Refresh, but have also tried using WebBrowser.Navigate(same page as before)). Is there any way that I can delete just that page in the cache without clearing the whole thing from my application before it reloads and calculates the new page length?
