View 1 RepliesI use the webbrowser control to navigate to certain websites and login and retrieve some data. For that I created a sub for each website. On the form i have a button that calls every sub when clicked. The problem is that I don't know how to pause or stop the process once started. If I quit the program it will still run in the background until all calls complete. I tried to use a thread, but that doesn't go well with the webbrowser control.
View 15 RepliesI am working with vb.net to making a form that prevents the web broswer on windows internet explorer from navigating to certian pages. The code can't just work on internet explorer because I could make a program with a web browser that navigates. It has to prevent the web browser itself from navigating.

I wish to read a web page that had various frames and div elements.To start with I would like to create a routine that justs lists all of those elements values and then display each element name and its value so I know what I have and how to reference it later on.I have been using the WebBrowser control and have managed to do a few basic things so far like go to a website and auto login.

I have used VB6 years ago. Few days ago I just got started again with VB 2010. So I'm newbie again, Almost forgot everything. I want to create a program for parental control that block specific websites.
What I exactly want to do is The code should check the titles of the open windows and see if it is blocked one. If it is, it will close the browser with a message showing it's blocked. For example If I put "yahoo" to check and someone opens yahoo.com it should be terminated.What I have done so far is, I made DOS batch file that will terminate all the browsers that are open and set that ready to run when the title matches blocked site name/address.But I am stuck at how I can check the titles of the window that are open.

I use webbrowser as File Explorer.
If you click folder it opens new folder contents in WB window but if you click html document it opens in EXTERNAL viewer.
How do you get html document to open in WB while exploring ?
I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.
i have created an app to load an access database into a datagridview, which contains web urls.

Ive tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?
View 6 RepliesI 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?
View 3 RepliesI have a WebBrowser control that have a webpage loaded in it. On the webpage I have a textarea control, like this:

Again the code clicks the button, but doesn't save the information so I figured it has something to do with the hidden value. I've never seen this problem before so I don't know where to go from here.
I have a webbrowser control, where I show images (bmp files, that the program creates), and I want to add some UserControls to setup the images (as showing layers, or choosing colors to display). Is easy to do appropiate UserControls on VB.NET, and I know almost nothing about HTML, so, I would like to add standard VB.NET UserControls near the images.

So I've got a button that adds a tab using the tabcontrol object.
TabControl1.TabPages.Add("Test")

Each tab will have the same components, but might goto a different url.
I'm tried to make my own web browser by using WebBrowser control in VB.NET 2010. When I run my program it is work fine but when I try to open any link in new window it is opened in Internet Explorer. So how can I start new window in my web browser?
View 2 RepliesI am writing a VB.Net WPF application that needs to display HTML content and websites. I am doing this using the webBrowser control. The application takes a significant performance hit running under x86 and I would really like to keep it set to Any-CPU. However the webBrowser controls need to be 32bit so they can run flash. So is there any way of achieving this? Running the 32-bit webBrowser in a 64bit process, or some alternative control that will manage this and allow me to load HTML from a string and a URL?
View 1 RepliesNow, for this particular project, I have to use the Webbrowser control in VB. I normally wouldn't, But I need to display some modified HTML. So here is my problem.

web.Navigate(TextBox1.Text)

The Msgbox comes up as soon as you click the button and is empty, No page source.
I'm having an issue loading one of our work websites in a WebBrowser control. In IE, it works fine, but in the wb control, it does not seem to process correctly.There is a frame, "mainframe" which when you click "result", goes back to the "to do list". However, i get a blank page in the frame, and then when i hit refresh, it comes up with a scripted error "Page Already Sent" which i'm not sure what it is triggered by.The pages are JSP pages, and i don't know if that might have some effect, but i'm more confused as to why they would work perfectly in IE, and then not work in WebBrowser control.
View 5 RepliesI'm running a webbrowser control with a custom user agent.when I try to load google with it, there are a number of 'script errors' in the website, which I've hidden by setting 'Scripterrorssupressed' to true. Now however there is still an 'object error' which pops up when i try to load google.Every other website that I've tried loads fine, and when I click 'ok' google runs fine. I'm quite sure its something to do with google 'location services' trying to locate my browser, because it thinks its a cellphone (due to the custom user agent).
