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.
Why does CPU usage jump so high when a WebBrowser control is navigating to a page?Is there a way to drop CPU usage?
View 17 RepliesI have this code set up to navigate to a certain .html document depending on what's selected from a ListBox:
Private Sub FileList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileList.SelectedIndexChanged
HelpWindow.Navigate(System.AppDomain.CurrentDomain.BaseDirectory & "help" & fileArray(FileList.SelectedIndex, 1))
End Sub
The problem is, when I first select something in the ListBox, it successfully navigates to that file and displays it. But when I select something a second time it doesn't change.
All of the paths it's trying to navigate to are correct. I've checked this 1000 times.
I am using a webbrowser control and loading a website that uses basic authentication. I pass the username and password in the additional header of the navigate routine. The problem is that the header is not retained while navigating the site.
I.E.I log into the site and pass the user name and password in the http header. When I click a link to access another page the header is removed and the site asks for credentials. If I was to just type the site into IE and log in the first time the headers are carried forward on all pages. how I can have the page retain the headers so the user never has to authenticate?
Dim sHeaders As String
Dim HelpBrowser As New WebBrowser
sHeaders = "Authorization: Basic: " & System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes("UserName:Password")) & Chr(13) & Chr(10)
Me.HelpBrowser.Navigate("http://www.mysite.com", True, Nothing, sHeaders)
I have a report where each group is about 5-7 pages long.
I need to suppress the page header on the first page of each group Also I want to Supress the header on each group change (on first age on group)
i am new to wpf and i try out navigation but i want some help when we navigate to a page other than the main page then its gonna have a back arrow in the top corner visible allowing to go back but i want that it should be hidden
View 11 RepliesI'm using the following code to populate a DataGridView with a worksheet. This is working fine, however, I'm unsure how I can get the Text from the page header. (not to be confused with the column header). Later in my code when I am exporting into an existing workbook with a new worksheet, I'm wanting to use the header text as the tab name. The header text being "September 2009" so that when I import/manipulate/export october, the new tab will be "October 2009" etc. [Code]
View 1 RepliesI'm automating a download,and I know the URL to the download page. Well, not exactly. This URL is indeed what I need to use, but the website redirects it to the REAL download page. Unfortunately the redirect only happens if I do an exit sub. That is to say, if I do a loop sleeping one second per iteration, the loop goes on forever waiting for the redirect. But if I branch out of the loop by inserting an Exit Sub in break mode, I can see the redirect occur onscreen. (I can watch the current page in the web browser transition to the desired download page). The trouble of course is that I don't WANT to do an Exit Sub at that point, so what's the solution? Do I need to call Browser.Navigate on a background thread?

View 16 RepliesI 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?

View 10 RepliesHi,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?
View 3 RepliesI 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.
View 6 RepliesI 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:

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.
