Windows - How To Tell If A Webpage Has Loaded Within A WebBrowser Control
Jul 11, 2011
I am trying to write a program that will tell my grandmother whether the internet is live or not. I know, I know, She just doesn't get it. So I want to create a program to load google.com or something and all I want the program to do is tell her whether the site was found or not. Is there a way to do this with the WebBrowser control?
I have implemented webbrowser control in my windows application. I have some functions inthe class file. i want to use those functions from the webpage which is displayed in my windows app through webbrowser control..For example say... I have an standalone windows software. Which has a webbrowser control in the some form. Now i would like to create a webpage that can be displayed in the webbrowser control in win app which has some buttons and textboxes. When i click on button in the webpage it should get the version number of that software. I have some other functions that are in the class file aswell.. but dont no how to call those functions from that webpage when a button is clicked or something like that.
I am using the WebBrowser control in VBE 2008 and I would like to know how do I detect when a frame has finished loading. The frame name is "LeftFrame".
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 ?
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've pulled down a webpage using a WebRequest object, and need to parse it, but first I need to render it since there is scripting on the page. I don't want to use the WebBrowser control because that forces me to jump out of my current function to the DocumentCompleted event, and "lose my place" (so to speak). Is there any way for me to pull down a URL using a WebRequest object and have the page rendered but still stay in my function?
I'm wanting to randomize the selection of a select box on a webpage via the webbrowser control.
What I can do.
Dim testRandom As String = curElement.InnerText Dim RandomSplit() As String = Split(testRandom, " ") Dim intRandom As Integer = RandomSplit.Length Dim curRandom As String = curElement.GetAttribute("Value") Dim rnd As Integer, randomNum As New Random
Got To Webpage without using webbrowser control?If so, how would i read / get the html of this page? I can do this now with a webbrowser control, but just looking for a quicker way.I've seen this online below.
Imports System Imports System.IO Imports System.Net
I am navigating to a website using a webbrowers control and I wish to automatically scroll the page after it is loaded. I have used scrolltop , scrollleft commands as set out below but nothing seems to happen. WebBrowser1.Document.Body.ScrollTop = 100 WebBrowser1.Document.Body.ScrollLeft = 200
I have placed the above commands in a command button and wait until the page has loaded before I press it and also in the WebBrowser1_DocumentCompleted sub
Other commands such as WebBrowser1.Document.Body.ScrollIntoView(True) Seem to work ok.
I have a VB program that uses a web browser control to navigate some websites for me but I need to click a button.
The button is in a frame and in a form with 4 buttons. I have already figured out how to navigate the individual frames and forms but I can't figure out how to click the button I need.[code]...
I have been working on this one for a couple of days now. The company I work for wants me to automate a login (coupled with a phone dialer) to a national Satellite retailer. When the call center individual gets a call the ACD system forwards them to a URL and is supposed to log them in. Unfortunately one of the sites heavily uses frames and I cannot programmatically autofill the userid and password and programmatically press the "OK" button on thee website. The website is: [URL]. I have been able to drill down and fill in the userid and password fields, but this has stopped working but I have never been able to Invoke the OK button event.
I know the code to find the input boxes in question.. basically the html is like so HTML <input type="text" name="username" class="inputbox"> i know enough to use WebBrowser1.Document.Forms.GetElementsByName("username") to find the text box...but I need to know how to send the contents of say TextBox1.text to the form on the web page...i can't figure it out for crap...I just assume give up and use sendkeys to tab to the textbox even thought its 80% unreliable....
This time I am stucked with a JSP page which is loaded in my webbrowser control. I have checked that it has been loaded. But I am unable to locate any of the controls of that page. Even in the count of any html controls it displays me 0. The page contains two frames and there is no "iFrames". Has Javascript got do anything with this?
I'm attempting to populate fields in a processing webpage [URL] and having a small problem.
I can add the email and antenna heights easily but how do I manipulate a file browser (file upload) and option input boxes (Antenna Type) from within my vb app?
It might be the long way around but i'm doing it via searching each of the html elements to find the named fields I'm looking for:
Dim intWork As Integer For intWork = 0 To WebBrowser1.Document.All.Count - 1 strWork = WebBrowser1.Document.All.Item(intWork).Name
Using VB.Net, how would I go about checking if a loaded page in a Web Browser object contains a certain line of text? Sorry if theres an obvious answer for this, I'm used to programming in Java.
programming and was trying to get a form button to load the yahoo login webpage, wait until the send button was loaded and auto enter the username and password and hit the send button. My code is as follows
Public Class WebLogin Dim ie As Object Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

I am making this program that has a loop that goes to a website and fills in a form within the loop. But first, here is my code thus far
Dim message As String = TextBox3.Text Dim loopnumber As Integer = TextBox4.Text 'makes the necessary variables Dim browser As New WebBrowser Dim url As String [Code] .....
But what happens is that the loop runs a few times then it errors on the setattribute line (line 19 above) with NullRefrenceException was unhandled And I have a feeling that it is not loading the page fully before it tries to fill in the form.
I have a vb windows application with 2 forms, where form2 is called from form1 using form2.showdialog()
I added a web browser control to form2, and I'm getting the following error at the point where form2 is called:
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.
I tried: 1) adding STAThread() to the form_load()
2) I added a module to my application, and created a sub main(), with the STAThread attribute applied to it
I have a WebBrowser control in my VB.NET application that loads a PHP page inside it. On the PHP page I have a 'Log Out' hyperlink. What I'm trying to do is close the VB.NET form when that hyperlink is clicked.
I can't seem to find a way to use the IE9 rendering engine in the WebBrowser control, instead of the IE7 rendering engine, using Visual Studio 2010 and Windows Forms.
XP WEBBROWSER-CONTROL: brings up PDF embedded in webbrowser control, as desired.XP IE7: Behaves the same if you manually navigate to URL, as desired.VISTA WEBBROWSER-CONTROL: brings up PDF by separately launching Acrobat, won't embed in webbrowser control. Not desired.Vista IE7: embeds PDF properly if you navigate to same URL, as desired.I am using Acrobat 9, where there is a preference setting under Internet to bring up PDF embedded in browser -- works fine directly in IE7, but not in webbrowser control.
I am writing a windows form application, where I want to have a WebBrowser control, and in that control, I want to show a Google map programmatically generated (I mean, not just specify a URL to the browser).
