.NET WebBrowser Control's DocumentCompleted Event Passes No PDisp Argument?
Sep 6, 2011
I have some experience developing for VBA inside Office apps, but I am quite new to VB.NET, and I just noticed that its WebBrowser control is a bit different from that one I used to reference via ShDocVw to use in my VBA Forms.ShDocVw.WebBrowser had the DocumentComplete event, which passed these arguments: URL as string and pDisp as object..NET WebBrowser has the DocumentCompleted event, in which i successfully found e.URL.ToString, but I couldn't find nothing similar to the pDisp object.
This is critical to me on migrating my project from VBA to VB.NET, for I need to handle particular IFrames when they complete loading, which I only could do by getting pDisp's document property. So I need help on learning how to do the same thing with this .NET WebBrowser control, and/or how to reference and use good ole ShDocVw.WebBroser in my Visual Studio project, to embed it in my forms.
i have a problem whith a webbrowser, when ocurred this event
Private Sub myweb_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles myweb.DocumentCompleted Console.WriteLine(myweb.Url.ToString()) End Sub
console write 2 o 3 times the same address, i need this event only one time
I want to get the full 100% Download Complete of whole webpage event.normally a webpage like Google With iFrame ,it will activate 2 times Download Complete Event.....Other like yahoo activate 3 times Any one know the method to know the fully completed event of webpage..Or the iframe count.
I am trying to get the event firing when document is ready. Public Class Form1 'Declaration Public Event DocumentCompleted As WebBrowserDocumentCompletedEventHandler Private Sub Main(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'Dim frm As New Form1 'frm.Show() [Code].....
As you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On. HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way
I am using visual studio 2005. i am using webBrowser control to automate third party website.My problem is SelectedIndexChanged event is not getting fired. I used the code.[code]This code is changing the value in combo box but it is not firing the selectedindexchanged event. If i manualy select the item then after selecting a item it shows different message. How should i do it programatically.
I'm trying to handle browser popups using the NewWindow event of the WebBrowser control. The one main thing I needed is the cookie from the main browser control on my form to be passed to the popup window. Below is the only way I've been able to open the popup and pass the Document.Window.Opener value to it so that when java script is executed, it knows where the opener window is. I am getting the following error right now when trying to set the cookie from my webbrowser control to the iexplore instance of the popup window that opened.
First off I hope I'm in the right forum.I have an application I built with the WebBrowser control in Visual Basic 2005. I am using the DocumentComplete event to track when a page has fully finished loading as some of the webpages I need to work with have frames.
The problem I am having is that when some iframes time out or don't load, the documentcomplete events stop firing. So if my webpage has 2 frames on it, we'd expect 3 documentcomplete events. One for each frame and one for the parent document once the frames have loaded. If say frame 2 does not load properly, the documentcomplete event for the overall document never fires.
Tried to look for a solution for this problem everywhere and can't seem to find it?I have found solutions related to sub-classing the document, but this method results in a Null Exception as there is no document.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a windows form and a webbrowser1. When it first loads, I pass acouple of arguments to the browsers url. Everything works fine until I minimize the form. I get an error: "invalid argument".The strange thing is if I subsitute the "http:[url]... it works.

I just have a short question about adding an destination methode as variable argument into my calling methode.
I want to send a "TextChanged" event to a special textbox. But I want to have a "variable" in my methode to add the handler to the textbox. Because it is possible to change the textbox and then I can change the handler where the "Changed Events" should be routed to.
can you replace the questionmarks below??
Dim TextBox1 as TextBox Dim TextBox2 as TextBox Private Sub DoIt
my current solution as you can see is by using shared variable within a class in order to pass a value.
on the form load of my application i called: workerSample.RunWorkerAsync
Dim finalList As List(Of String) Private Sub workerSample_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles workerSample.DoWork
My goal is to have the user be able to click the row and the row will be the selected row almost like having the select button but the entire row clickable to do the same thingthe error i get popups when i click the row, not when the webpage is loaded
this is the onrowdatabound portion i just added that causes the error If e.Row.RowType = DataControlRowType.DataRow Then ' Get reference to button field in the gridview.
I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...

I am trying to wait for the webbrowsers page to have finished loading to then carry out the next part of my code.However i am having problems because the DocumentCompleted event fires twice?
This is a good way to use DocumentCompleted using AddHandler (good for a tabbed web browser) [code] Of course,.you can adapt this for a tabbed WebBrowser by replacing me.text with tabcontrol1.SelectedTab.Text.
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. 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 am trying to get an HTML source from 3 different web pages. To navigate these 3 pages there is a dropdown menu with 3 items: Page 1, Page 2 and Page 3.These 3 pages are loaded using ajax in an empty div.
What I am doing at the moment is:Selecting the first item from the dropdown menu and simulate a click
I currently have two subs in Webbrowser3.DocumentCompleted. The first sub scrolls the web page to a specific point. The second sub takes a screenshot of the webbrowser window.Problem: Screenshot image is recording the top edge of the webbrowser. This means it is not scrolling to the right position before snapping the screenshot.
My guess is that the web page is not fully loaded when DocumentCompleted is called. Or the scroll is not being completed til after the screenshot has been taken. Result: After this is run, I end up with an image of the top edge of the browser. The Webbrowser is scrolled to the right place, but the image is taken before it gets there.
I have read through many of the questions related to my situation but I have not found one that does. I currently have a repeater with 4 bound items to it, clicking on a button in the repeater causes my error, below is the markup and codebehind. Can someone explain to me why this is happening and the fix for it? (I have excluded the page decleration and just included the page_load event. let me know if i should cut and past full code in)
Perhaps this is nothing weird, but it is in my eyes. After loading the webpage I want to hide the progressbar on my ParentPage, but it keeps coming back. Here's an example of my
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?

Works beautifully on my machine, but on three others i have tested it on, it opens PDF and TXT files no problem, but as soon as I attempt to open a Word file or an Excel file I get "There is not enough memory or disk space to open Word" and similar in Excel if the application is not already open. If the Office app is open, the code works perfectly. Has anyone come across this before?
