View 10 RepliesI'm writing an application that queries a web page for information. I'm using a WebBrowser control to access the page that contains the info I'm looking for because I need the application to log in to the website and navigate to the desired page.
My code:
Dim wb As WebBrowser = New WebBrowser
wb.Navigate("http://somewebsite:80")
While wb.ReadyState <> WebBrowserReadyState.Complete

View 1 RepliesI am attempting to fill the zip code through on Target Mobile Find in Store and click the GO button. However the button does not have an ID when I look at the HTML. I am able to fill the zipcode text box using:
WebBrowser1.Document.GetElementById("zipcode").Inn erText = txtZip.Text
but I cannot figure out how to click the button. I've tried using sendkeys.send("{enter}") but that doesnt seem to do anything.How can I either send the enter key after filling the zipcode or click the button?

What I'm trying to do is click an html link inside of a html table via code in vb.net using a web-browser control. The link I want to click can be anywhere in the first column of the table so I need to cross reference with another column in the table to make sure I have the re way I'm going about this is to loop through the html elements till I find the table I want (multiple tables on the page) then dump that table to an array. Then loop through the page again get to the table I want and then start comparing the link and another column in the now array. I need to check to make sure that the url of the link contains a work and that another column in the table contains a specific or lower numerical value. Basically where I'm stuck is while dealing with the html element "Table" wanting to identify and interact with another html element inside it.
'Flag to say dump to array
Dim RecordFiles As Boolean = False
'The last two headers in the table are blank so need to skip them
Dim FirstBlank As Boolean = False
Dim SecondBlank As Boolean = False

View 2 RepliesI wish to read a web page that had various frames and div elements.To start with I would like to create a routine that justs lists all of those elements values and then display each element name and its value so I know what I have and how to reference it later on.I have been using the WebBrowser control and have managed to do a few basic things so far like go to a website and auto login.

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 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.
View 5 RepliesI'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
AddHandler Me.WebBrowser1.Document.ContextMenuShowing, AddressOf WebContextMenuShowing
WebBrowser1.ContextMenu.Dispose()
WebBrowser1.ContextMenu.Show(WebBrowser1, pas)
End Sub

i am trying to make a webbrowser in VB2010, but one major roadblock that has been in my way for a while, is the fact that i can't get my bookmarks bar to work
i have no code to show you and i am completely open to ideas as long as i use a toolstrip just make sure that the bookmarks work and they are Saved when the program is closed and opened again.
Notes:
instead of "WebBrowser1" use:
"
CType(TabControl1.SelectedTab.AttachedControl.Controls.Item(0), WebBrowser).PutWhateverHere()
"
(i am using a dotnetbar tabcontrol so i need the "AttachedControl")
the toolstrip i am using in this case is called "BookmarksBar" so please don't use "ToolStrip1"
I was just wondering if their was a way to get element by id without webbrowser?
View 5 RepliesI'm writing a program for my sister for a game which she plays online. It uses a WebBrowser control, and HttpWebRequest as well.The basic function is it searches through the website, we'll say the url is http://hersite.com/pet/* (don't follow the link lol it's just an example) where * is a number and this is how it searches.I use a for loop to cycle the numbers from a specified start to end, and use an httpwebrequest to fetch the html code, then process the string using InStr and .split()When I access the webpage using the WebRequest.Navigate, it takes me to the page correctly. However, if I fetch the source through the HttpWebRequest, it fetches the source of the login page, which the website redircts you to if you are not logged in.Is there a way to transfer the cookies from the WebBrowser to my HttpWebRequest?
Some examples:Get the HTML somewhere in here I need to add the cookie to the http requester, don't I?
Function GetHTML(ByVal strPage As String) As String
Dim strReply As String = "NULL"
Try
Dim objHttpRequest As System.Net.HttpWebRequest

I am trying to gather text information from a website. There is a list of "Prices" and I want to collect the Price text of the very first one. Since the very first item is the very first item in the Documents HTML, I figure it is possible. [code] So as you can see I don't have much to go on. and this exact code is followed more down the Document, but with different numbers. So please, is there a way to collect the "R$250" and then stop there?

View 14 RepliesI know that in a WebBrowser you can use Document.GetElementById to find an element by its name attribute, but I want to search the webpage for an element using the id or class atributes, how would it be possible to do this in a WebBrowser? I want to make it click on an image tag.
