VS 2008 Paint On A Webbrowser Control?
Mar 27, 2010I've looked everywhere, but I havn't found anything on how to paint on a webbrowser control. I tried to do it with a transparant panel over it, but that didn't work.

View 5 RepliesI'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.
Put a picturebox1 on a form2, and paste the following into form2 public class. When you run it you will see nothing untill you force a paint event by mouse dragging the form half off the screen. If you minimize - then maximise - the image dissappears and the picturebox1 does not repaint itself??? I want the picturebox1 to be "auto drawn" somehow.

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.

View 2 RepliesI need a multiline TextBox which is always disabled, but it shouldn't paint itself in gray, but I want to keep its designer choosen color. I previously had the same requirement with an always-black Label (no multiline) and so I inherited from Label like:
Imports System.ComponentModel
Public Class LabelDisabled
Inherits Label
Sub New()
InitializeComponent()
Enabled = False
End Sub

But this way, neither I can set the "real" Enabled property, I mean the backing field.
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.

View 1 RepliesI have created a VB.NET project that includes WebBrowser control. The web browser control navigates to html page that embedes a flash movie.

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.

View 3 RepliesI 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?

The webbrowser control in vb 2008 is an instanse of IE.But i want to build my 'own' webbrowser, with custom contextmenustrip, navigate error messages ,etc
The web browser control that comes with visual basic 2008 is out-dated and is very slow to load a lot of newer web pages. How do I go about updating it?
Also, is it possible to use Google Chrome or Mozilla Firefox instead? Would I be able to use code like this in any of the newer browsers?:
