View 5 RepliesI am working on an application and I need urgent help. One of my forms contains a web browser. I need to detect if F3 key is pressed while the web browser is active, so a dialog box will appear for a particular functionality of the application. But unfortunately web browser control does not have keyup, keydown or similar event to help me detect if the F3 key is pressed. As far as I know, one way to solve this problem is adding a menu which has F3 shortcut. But my application does not contain any menus, so I dont want use a menu in this part of the application.
View 1 RepliesHere is a setting called PopUpBlockerEnabled:And here is my Addhandler code when the browser is being created on form1_load:
AddHandler Browser.ProgressChanged, AddressOf Loading
AddHandler Browser.DocumentCompleted, AddressOf Done

I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

Is there a way to work the web browser control for viewing off-line (Cached web pages) only? Is it possible to view cached web pages from IE9 on a web browser control off-line? The reason i am asking this question is because IE9 automatically switches from off-line mode to on-line mode when it cannot find something in the cache by default. For forensic purposes this is not acceptable for these reasons: Active content (Viruses, java script, activex cookies etc)

The below code allows me to login to a site using HttpWebRequest however I can't login to the site [URL] (which is the one I want to login to). At the bottom of the code I write the source to a file and upon opening it simply shows the login page.
After looking at the source I believe the issue is caused by the form calling a javascript funciton to actually submit the form when the 'Login' button is clicked. Has anyone had this type of situation in the past and if so what was the solution to get the form to submit?

i have a site that i would like to login using httpwebrequest.I have this code and added the correct part to post
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim postData As String = "u_name=" & TextBox1.Text & "&p_word=" & TextBox2.Text & "&login=Login"
Dim tempCookies As New CookieContainer
Dim encoding As New UTF8Encoding

If i enter the wrong login info it says bad login, but if i add the correct login info, it does not login, all it does is displays the login page again?
This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?
I'm using the following code to set the proxy on an HTTPWebRequest:
Dim proxy As New WebProxy("HOST:PORT")
...Then...
' Goto the final URL
request = CType(WebRequest.Create("[URL]"), HttpWebRequest)
request.Proxy = curProxy

Now I put in a valid Proxy, don't run into any problems applying it, but IPChicken will always return my IP address, not that of the proxy.
I am using GET and POST webrequests and am trying to set the User-Agent.

request.Method = "POST"
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postdata)

The above is what I tried to set the user-agent but it returns an error saying that I'm not properly setting it.

I'm looking for a way to fill in various website details using a HttpWebRequest/WebClient. I can manage it quite easily using an invisible WebBrowser control, by manipulating the HtmlDocument, but for some reason I just can't quite grasp the way I would do it with a HttpWebRequest/WebClient. I've heard both of these can potentially submit info using the UploadData functionality etc, but I'm missing specificsI've done a lot of searching on google just for a basic example to get me started, but the only one that LOOKED informative was written entirely in German.Take, for example, this website. Let's just say I wanted to automate filling in my username and password into their respective boxes and then pressing the "submit" button. How would I start going about this, and how do I get the resulting page? (I'm assuming cookies that the page creates will keep your next webrequest going)
