View 8 RepliesI've made a tabbed web browser and I'm using
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Stop()
instead of WebBrowser1.Stop() for navigating.
but I want to know when a web page has finished loading?
Normally the following works, but not with tabs
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
End Sub
how to cause it so that my program will not proceed while a web page is loading. For example, if I use this:
webbrowser1.navigate(www.amazon.com")
sometimes it will have finished loading the webpage before the program proceeds. Other times, even if it says it is done, it is not done and it causes my program to crash.
how I can cause my program to stop and wait until it is sure the webbrowser has completed loading?

View 6 RepliesI typically write my own servers, javascript, etc in vi. I've been given a project to enhance a VB.Net / ASP.Net application and I'm having some troubles figuring out how to get the user control to render BEFORE the page finishes loading.When I use normal browser as the viewer, everything works OK. When I try to use generate the page as a report, the report generator spits out the PDF while my JavaScript graph drawing stuff is still in it's initialize functions.They are using EvoPDF as the PDF generator. It appears the page is being considered complete after the page is loaded but before the javascript is executed.I admit I'm a bit lost when it comes to ASP.NET, but I know HTML/HTTP/JavaScript very well.How can I force the page load to wait until my usercontrol finishes rendering?
View 2 RepliesFirst off the Treelist does not display data until it is almost finished loading the files. I tried to refresh the treelist but it still does the same.
Private Sub BtnBrowse_Click(sender As System.Object, e As System.EventArgs) Handles BtnBrowse.Click
Try
If FolderBrowserDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
' List files in the folder.

Well I know this could work for a browser with no tabs:
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
End Sub
But the thing is, I do have a tabbed browser. I tried this code, But it didn't work.

I have some code that needs to be executed right after the page has been loaded inwebbrowser controli tried numerous things like if webbrowser.isbusy = false...but that will check it only one time, and when it's executedwebbrowser control doesnt wait for page toload to continue executing program, so it's no use to put my code after webbrowser.navigate
View 4 RepliesI've got a webbrowser. It's prettey advanced, given that I've spent quite a lot of time coding it, and here is my code which will get the Favicon of the current website when a the webbrowser has finished navigating:
frmBrowser.BrowserTabs.SelectedTab.Icon = Controller.GetFavicon(Me.Url.Host & "/favicon.ico")
Sometimes, a user has switched tabs before the webbrowser has finished navigating. So my question is: Is there any way in which I can determine what tab the favicon belongs to and set it to that tab, rather than just setting the favicon to the selected tab?
I want to use a progressbar while loading, which means I need to COUNT.
vb.net
Dim mysqlCount As New MySqlCommand("SELECT COUNT (*) FROM tableName AS tableCount", mysqlConn)
Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '*) FROM tableName AS tableCount' at line 1
I really don't understand why this occurs. The connection works fine btw. So no issue(s) there.
I've been trying to solve this problem for quite some time. I have an application that uses the WebBrowser control to provide some navigation capabilities to the user but depending on what website the user is going, there are some syntax errors coming up. These erros would normally not disturb the user under Internet Explorer so I'm trying to hide them some how.

there's an img src=blah on a web page that I am loading with a webbrowser control, and I want to alter it to say img src=blahblah instead ... What I've been doing so far is waiting for the document to complete, doing a .replace, then saving the file to the hard drive, and finally navigating to that local altered version.I was wondering if it's possible to skip the step of replacing and reloading the local page, and instead, just dynamically alter the original source code of the page AS it's loading the first time. Can this be done?

I need to get the url of the webpage the webbrowser is navigating to, but since the code executes faster than the webbrowser navigates to the webpage, it gets the url of the last page. I cant use DocumentComplete Event because i have a tabbed browser,
and i cant write events because im creating tabs(with webbrowsers) at run-time. So how would i check to see if the webbrowser has loaded a document?
How do i do that ? I want to wait until the webbrowser has loaded the document and then add the document text to a textbox... How do I do that ?

View 5 RepliesWebBrowser Example.zip IntroductionBecause the WebBrowser control that we use in .NET is a COM control, not all of its uses are straightforward and some of them (even those which seem like they should be easy) require that we dip into our Interop toolbox in order to properly implement them.
A perfect example of this is loading HTML content into the WebBrowser from memory, rather than a file or a URL. Anyone who's ever used the WebBrowser control before is familiar with the Navigate2 method, which tells the control to load content from a URL (or path to a file). Loading HTML content from memory, however, is a rather elusive practice because of the many steps involved in making it work.
MSHTML.HTMLDocumentYou might notice that the WebBrowser control exposes a "document" property. The object returned by this property can be coerced to the type of "mshtml.HTMLDocument" (you must add a reference to MSHTML to your project in order to make this work) as follows:
Code:Dim clsDocument As mshtml.HTMLDocument = CType(WebBrowser.Document, mshtml.HTMLDocument)
(NOTE: You will have to add a reference to the COM library MSHTML to your project to make this compile)
Once we create an instance of HTMLDocument, a whole new world opens up to us, providing all sorts of DOM access to the content of any given Web page.
If we were to create our own HTMLDocument object from memory, we could use the "write" method to write HTML content to the document from a string variable, like this:
Code:'initialize the document object within the HTMLDocument class... clsDocument.close() clsDocument.open("about:blank")
'write the HTML to the document using the MSHTML "write" method... Dim clsHTML() As Object = {sHTML} m_clsDocument.write(clsHTML) clsHTML= Nothing
WebBrowser Control ImplementationUsing the HTMLDocument returned by the "document" property of the WebBrowser control, however, is not as straight-forward. Because of the way that this object is created and initialized in memory (by the COM WebBrowser control), the "write" method fails when called as above. In order to write content to the HTMLDocument exposed by the WebBrowser control, we must first marshal the string value to a memory space that is compatible with COM. Once the string is properly marshalled, the COM interface IPersistStreamInit (implemented by the HTMLDocument class) must be used to pass the value into the object.
Interop DeclarationsIn order to pull all of this off, we must declare several Interop pieces, including an enumeration, a function, and two interfaces. The declarations for these pieces are as follows:

Is it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.
All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.
I currently have a main page called "ShowFrames.php" that has this html code in it:
[Code]...
I have loaded "ShowFrames.php" onto my WebBrowser1 control and it loads both of the frames onto the webbrowser control. Now my question is, how can I get the source of either of the iframes WITHOUT loading that frame by itself? For instance, when you load 2 frames on a screen in Firefox, it lets you right click on it, and select "This Frame" > "View Source" so you can view the sources separately. Can anyone tell me how I can duplicate this and put the source in variable strSource? I know that to get source code for a page, you need this WebBrowser1.Document.Body.InnerHtml But I dont know where to go from there in order to get a specific iframe's source.
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.
