Different Webbrowser Control - Web Based Apps Which Will Require A Webbrowser Extension
Aug 10, 2010
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.
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?
How do I simulate mouse click on webbrowser control based on coordinates (x, y).Coordinates of the webbrowser control. I wanna click a specific location on the webbrowser.
i have created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox. This all work fine but after a while the webbrowser navigation becomes increasingly slower.
For Each RW As DataGridViewRow In Me.DataGridView1.SelectedRows '''''''''''#######cell values into strings ########'''''''''''''' If RW.Selected = True Then Dim domain As String
I'd like to integrate Webkit.NET into a VB project, but I'm not having any luck so far. The Webkit.NET tutorial page gives a demonstration in C#, so I assume that it's possible to use this in VB.NET as well? [URL]
I added the control to the project successfully, but since I'm not familiar with C#, I haven't been able to convert the code successfully (even after running the code through a few different online C# to VB.NET converters). So... has anyone gotten Webkit.NET (or any Webkit-based browser) to work in VB.NET? Or am I just dreaming? I would love to be able to use the default .NET WebBrowser control for this project, but this project requires doing a few things that the IE browser is not capable of (but Webkit can do it easily).
what WPF based apps are?Is it an application that runs under Silverlight? If so, how?I know; Windows Forms based apps,console apps,DLL _ Class Library Projectsand I've had an introduction to ASP.Net.What I mostly want to know is, if WPF apps are for Silverlight then do they also run in a server based fashion like anASP.NET website would when you create ASP.Net webpages?Is it a way of creating what looks like a FORMS BASED application but it runs in a browser instead or what?Please enlighten me a bit further as I have no idea what WPF is all about.
I have a vb app with a webbrowser, and I am trying to search a page with about 1,000 links to click on the right one. Hereare some links from the page source:
HTML <tr> <td align="center"><input type="checkbox" name="checkedfund" value="9950::Custom"></td> <td>ING LifeStyle Moderate Growth Portfolio - Service Class</td>[code].....
I want to be able to find and click on a link in the page based on its name, like "ING LifeStyle Moderate Growth Portfolio - Service Class" for the first one. Also, I want the second link in each block, with the onClick=notesWindow function. How can I do this?
I'm having some issues with the suppression of the typical javascript and other scripting errors that show in the webbrowser.I have three webbrowsers. The third webbrowser goes out and determines some action based upon location. The one thing I'm having trouble with is this example. It states that it should work but the errors keep on coming.I attached some of the code below. Am I doing something wrong?
how can i make my webbrowser open up a new link in my same webbrowser or in another form? basically what im saying is i dont want it opening links in internet explorer.
I am utilizing a webbrowser control in vb.net 2005 to display excel workbooks
We are using this control to open excel documents. Webbrowser.ShowSaveAsDialog() allows the user to save the excel workbook open at any location he wants
However, I don't want the user to decide where to save. Is there any way to save an excel document from the webbrowser control without going through the ShowSaveAsDialog?
On closing of webbrowser, a simple prompt to user whether he/she would like to save changes should be fine enough
As of now, I can close webbrowser control and it does not prompt the user to save the changes. Actually, all changes are lost until and unless I perform a save (Ctrl+S) manually
I want to make a webbrowser, but only have it show one specific thing and not the whole page. The thing I want it to show and only show is in about the middle. How would I frame the page, and put it on the webbrowser?
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 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?
I 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?
Now, 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.
Dim htmlorig As String Status.Text = "Loading: " & TextBox1.Text web.Navigate(TextBox1.Text)
[Code]....
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.
I'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).
Code: Public Class Form1 Dim m As String() Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click m = TextBox1.Text.Split(Environment.NewLine)
[code]....
it navigates only to the last website [URL] i think that's because the for loop is faster that navigation process?
I've downloaded and installed the control from here, but I can't get it to work! I've added the component so it appears in my toolbox, but when i try to draw it on a form it isn't visible. It size can't be changed from 0,0 or anything! I can't see a 'URL' section in its properties either, why is that?
In my program, when the user clicks a button, a new tab is added to my tabpage and a WebBrowser is added to the tab. I want to be able to access the WebBrowser in the tab without having to give it a name when I add it.
I am creating an application for my own use in Vb.net to auto fill forms and submit the form (log in) to various websites....(bank sites, credit cards etc..the require a login)
I am using the webbrowser control on my windows form and I can sucessfully populate the controls on the form (userid, password etc), by setting the value property of the HTML Form Element using... HtmlDocument.GetElementsByTagName("Input").
My problem is that I cannot click the login button via code, sometimes it's an image and sometimes it's an actual button depending on the site that I'm auto logging in to, in both cqases the end result should me submitting the form.
Is it possible to autosize a webbrowser control? I mean I want it to be just big enough to show whatever HTML content I load into it (without scrolling), and no talller.
Or, alternatively, how do I find the height of a given HTML document? Once I do that, setting the height of the Web Browser is easy.
I've been working on a project that requires that I can go around webpages with different proxies, user-agents, and clear cookies. Now after looking all around the net, it looks like there are some solutions for each of these, but I can never get them working. I was wondering if there was a wrapper for this control that fixed all of these problems or even just a different control I could include.
I am using the WebBrowser control in a windows form C# project and wanted to know if there are any limitations of how many instances of such application you can have running at the same time. (in other words does MSFT enforce any limitations other than physical machine limits - CPU/memory etc)
