Webbrowser Control Resize Isn't Resizing My Web Page Controls
Nov 12, 2009
First off I'm using the Extended Webbrowser control from: [URL]
I use the Webbrowser control to access an ESRI web based mapping solution. When the ESRI map is loaded into an IE browser and the browser is resized then the map control resizing accordingly. When my Webbrowser control is resized the map webpage is not resizing properly.
I don't even know where to start with this problem. Is there some event that's not firing in the website? I can't simply refresh the whole website because the user may have panned and zoomed around. I want to just tell the website that the container control (Webbrowser control) is resizing now.

Where is the best place to resize a control on a form when a form is resized?....I'm currently using the Form1_SizeChanged event and seems to work ok. Also is there any need to check in the forms resize event if the form is in a minimized state before resizing controls?.,.. in VB6 if you try to resize a control when the form is minimized you get an error, but I don't see that happening in BV10 Form1_SizeChanged event, does VB10 automatically ignore resizing controls when a form is minimized or something?

im trying to find a way of resizing a html document to fit inside my browser correctly.
I would like the width of the page to be the same width of the browser. I can scroll down for the rest. I have no idea on how to do this. Ive found some bits and pieces on the net but nothing is working for me.
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
[Code].....

I'm using this control in a application to load the URL of a .jpg image. The thing is that the image is bigger than the control, so I want it to automatically resize the image, as IE does when the same thing happens there, and it even shows a little magnifier glass to restore the image to full size.How can this be achieved? What happens at default is that the image is bigger than the control, so a quarter of it shows and I have to scroll to see the rest.

I've got a set of controls in a line inside"FollowTableLayoutPanel1", contained within "TableLayoutPanel2".I have them resizing according to the position of the mouse cursor; the closer the mouse cursor is to the vertical centre of the control, the larger the control is. Because FollowTableLayoutPanel1 has its anchor property set to "Top", it recentres itself in TableLayoutPanel2.It is possible for the recentring of FollowTableLayoutPanel1 to move a control one pixel further away from the mouse pointer, which causes the control to shrink, which causes FollowTableLayoutPanel1 to recentre, placing the control closer to the mouse pointer, which causes the control to grow,which causes FollowTableLayoutPanel1 to recentre, which moves the control further away from the mouse cursor, etc., etc., etc.The end result is that the whole setup judders and wobbles, constantly resizing.Full example code is provided below,and can be pasted directly into Form1 of a new project. Positioning the mouse cursor to correctly show the problem is left as an exercise for the reader :
Public Class Form1
Private Sub myInitializeComponent()
Me.components = New System.ComponentModel.Container
Me.TableLayoutPanel2 = New System.Windows.Forms.TableLayoutPanel[code].....

I have a web browser control, what I use is:
Ret = (MainBrowser.ReadyState <> WebBrowserReadyState.Complete Or MainBrowser.IsBusy)
If ret is true, not loaded, otherwise, loaded. It works fine on winxp, however, on vista, most times, it works, sometimes, not. Do I have to use documentcomplete for this? The page is loaded from another thread, does it matter?

I'm using a webbrowser control in my program and I navigate to a page that uses sessions. I need to delete them somehow and I tried to close IE and enter it again and it worked, the sessions were deleted. But I've done it manually, and I need to do it through my program, so is there a way to imitate the closing and reopening of my webbrowser control?

I am navigating to a web page with my webbrowser control
[Code]...
and this works on most pages. Now I'm going to a page that I guess there are errors in the page and I get a box asking me if I want to debut in IE's built in script debugger or something to that effect. Is there any way to have the system ignore this message and continue to load the page as normal

Hi,I need to see if a webpage displayed via the web browser control contains certain words .I've tried parasing through the html but that contains too much junk html and css tags which caused problems(I've tried using regex to remove them).That was done by using property webBrowser.document.Body.InnerText.contains .
Are any way to search through the actual text on the webbrowser and not html via the program in ways similar control-f function on most webbrowser but using code to do that ?

I am using web browser control in one of my forms for displaying html files (local files). Before I load the next file I want to clear the webbrowser control of the previous page. I am trying the following method which I found while searching the net.
private Sub ClearWebBrowser(ByVal wb As WebBrowser)
Dim tempDoc As IHTMLDocument2 = CType(wb.Document.DomDocument, IHTMLDocument2)
tempDoc.write("")
tempDoc.close()
End Sub
I have added the reference for mshtml namespace in com tab. When trying to run the program, error is thrown like "Type 'IHTMLDocument2' is not defined. (BC30002)".

I'm using a WebBrowser control in my current program in a bit of a bastardized way: I don't use it visually, I just use it because I'm more familiar with its events.
So, basically, I create a WebBrowser control and navigate to a page to login. Then, when logged in, I create a new WebBrowser control and navigate to a different page.
I've used this program for four months with no difficulty. Starting today, though, the second phase of that has been going really, really slowly. What used to take 3-5 seconds is taking 25-30 seconds. It still works eventually, it just takes a while.
Usually I would assume this was a server problem. However, navigating to the exact same URL in Firefox happens extremely quickly. Weirder still, within the program there is a user WebBrowser control -- I can copy/paste the URL the previous (not visible) WebBrowser was navigating toward into this user WebBrowser, and it goes just fine.
What in the world could be holding up this other "custom" WebBrowser? I don't even know where to begin in diagnosing this.It might be important to note that the site this is working based off recently underwent some changes -- but I can't imagine why that would affect only these "custom" WebBrowsers and not the user one in the same program.

How can I get a list of ALL links on a page after browsing to a page via the webbrowser control?

I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.

I am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page. This works fine in IE 7 and Firefox.I then want to access this extra content in my program. Having found the HTML element containing the link, I tried element.InvokeMember("click"). I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link. I also tried setting the focus to the link element and using SendKeys to send the ENTER key, but all to no avail. Nothing seems to happen. I don't see the extra content produced by the JavaScript, nor do I get an error.Here is an extract from the HTML, showing the relevant (I hope) code:

Here is my code:
Dim TestHeader As String = "Referer: [URL]"
If chkRefferer.Checked = True Then
WebBrowser1.Navigate(cmbUrl.Text, False, Nothing, TestHeader)
Else
WebBrowser1.Navigate(cmbUrl.Text)
End If
Whenever I try and browse to a page with the 'TestHeader', IE opens up and goes to the page.... However, if I navigate to the same page without the additional header, it loads up fine in my webbrowser control.

I have a webbrowser control and the following code is in a for next loop. If I use wba = New WebBrowser the code works in the background and I don't see the loaded pages in the webbrowser control. My question is how can I see the results in webbrowser component with wba=New WebBrowser ?
wba = New WebBrowser
AddHandler wba.DocumentCompleted, AddressOf wb_DocumentCompleted
TheLoginUrl = Items(2) & "/test.php"
wba.Navigate(New Uri(TheLoginUrl))
results.Text &= "Login to: " & Items(2) & vbNewLine

In my userform I have a WebBrowser control to load PDF files. I have added a FolderBrowserDialog to allow user selection of drives and or folders.
What I am trying to do now is after a file has been selected and viewed, the user may want to change drives and or folder locations. How do I remove the current contents of the WebBrowser control to be a blank screen (just like when the app starts, its blank).

I am trying to figure out if the text from a website is visible when the page is rendered in a webbrowser control. The text I am looking for is error text that shows form field errors after a bad post submission. I've checked the source code of the html being returned and the actual html for the text i'm looking for is present before any errors are made, and after the errors are detected. is there any way i can do a sort of .visible check on html elements in a webbrowser object, or even check the css that is linked to a particular div/label/span for the visibility/display style tags?

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.
