I am sending web requests to a site and getting the responsestream and would like to perform the button click programatically, here is the tag for the event:
Next ยป
any ideas appreciated?
I used a web browser control... it might not have been the best approach since I don't know what page it's on, but here's my code:
Dim wb As WebBrowser = New WebBrowser
wb.Navigate("http://www.mydomain.com")
wb.Document.GetElementsByTagName("a")(2).InvokeMember("click")
This basically "clicks" the 3rd (the array is 0-based) tag on the current page.

If htmlElem.TagName = "HTML" Then

Short answer: What you are trying to achieve is not possible.
Long answer:
Each web browser has its own way of managing the HTML DOM. There isn't a universal solution that'll work for all of them.
The only way this can be done is if you get ahold of an API for each web browser you want to target, and then decide which API to use based on which the user has installed as his/her default. Doing so will require A LOT of time and effort, but it is technically possible (assuming the browsers you want to target have a public API that can be used for automation).
I'm scraping website which has a very annoying link (<a> HTML tag) - it opens the small pop-up form on click and after submitting it, opens new browser tab (and switches focus to it) with URL that I need, and also redirects old tab to another page.
Successful submitting of the pop-up form was easy, but I don't know how to get URL of this new tab.
And as the documentation says, Splash can work only with one tab, so is it impossible to do that?
As Splash's developer comments on this GitHub issue this feature is not implemented.
But I posted my solution to this problem on the same issue.
Example:
function main(splash, args)
assert(splash:go(args.url)) -- execute JS code below only after loading the page
splash:runjs("var newTabURL")
splash:runjs("newTabURL = null") -- sometimes JS can't find variable without this line
splash:runjs("window.open = function(url){newTabURL = url}")
-- actions which open the new tab
local new_tab_url = splash:evaljs("newTabURL")
-- other actions
end
how can i open an asp.net MVC view page in new tab. I have a left panel from where you will redirect to new page and i need to open that page in new tab of existing project not in new window.And also from ExtJS Sencha grid cell click.
Isn't it the anchor attribute target http://www.w3schools.com/tags/tag_a.asp what you are looking for? If yes then look here Opening a link in a new tab for the details how to use it.
You can't to this in a standard way.
Opening pages in new tab or new window, is a browser configurable option, not a programmable manner. So, you haven't any control over it.
However, opening new pages(whether in new tabs or new pages) is achieved in client side by this javascript line:
window.open();
Now, you have two ways in front:
1) You just want to open a new tab/page and request a view. Just set the url in the open() method:
window.open('#Url.Action(...)');
2) You send some data to controller and want to show the results in new tab/page.
First, send an ajax or ordinary post request to the controller and retrieve results in the same view.
Then, open a new tab/page and put that result to it:
var w = window.open();
$(w.document.body).html(content.responseText);
I am new to web browser control geckoFx. I want to login to a webpage using it. So how can i do it in vb.net
I tried navigating to the webpage using navigate method.
InitializeComponent()
Xpcom.Initialize("D:\xulrunner")
myBrowser = New GeckoWebBrowser()
myBrowser.Parent = Me
myBrowser.Dock = DockStyle.Fill
myBrowser.Navigate("www.google.com")
But how can i login to website?
I tried searching for few examples of using gecko.But i didn't get. So where i can get examples related to using gecko?
There are a number of different ways to do this. After you have navigate to the page and it has finished loading:
execute some javascript to fill in the fields and click the submit button.
C# javascript execute examples
use C# (or vb.net) to get the required DOM fields, modify them with the required values, then get the DOM submit button and call the click api.
Examples of GetElementById
GeckoInputElement class that has a click method
This is my first question so hello and thanks for your support!
I am currently developing a windows 8 store app.
I need to login to an OAUTH website and get the response token to save as a string.
I would like this to appear in a popup, have the user login, then close once a response is received.
I can get the webview to pop up and I can navigate to the page. But how do i handle the response and close. I speak VB.
Thanks again!
Edited to add my code:
Dim url As New Uri("https://aurlthatidontcontrol")
WebView1.Navigate(url)
PopUp.IsOpen = True
MY popup opens and the login for the url is presented.
Once I log in I should get a response from that server which includes an access token
I want to get that token into my app and save it as a string, then close the popup
Ok I figure it out.
Instead of actually calling a webview I used the web-broker authentication. Details
This allows the service login to "pop" on the screen and I can capture the result like this:
Dim webresult As WebAuthenticationResult = Await
WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, StartURI, endURI)
Dim finalresponse() As String = webresult.ResponseData.ToString.Split("=")
Dim currentuserstoken As String = finalresponse(1)
Return currentuserstoken
Use the InvokeScript method on the WebView class to call JavaScript code to collect information from the response and return it the calling code. If there is no script in the page you control, use "eval" as the function name and pass arguments to it.
Alternatively, use window.external.notify in JavaScript to fire the ScriptNotify event (link includes an example).
