I need to grab some data from a webpage but for me the main problem is I can't grab the data the way I want. I want to grab the data in a listview control but my code is fetching all data within any span tag (span class "inputFieldLabel" which is not required) in a single column of a listview control. I am giving the format (source) of the webpage below and my coding in vb.net (2008),
<br>
<span class="inputFieldLabel">Following Are ...</span>
<span class="inputFieldLabel">01/02/2011</span>
<span class="inputFieldLabel">And</span>

I'm using visual basic 2010 express..I'm building my own web browser and want to add a download manager.I have been able to build one that will download a file if I type the file location into a text box.What I'm trying to figure out is how to have the download manager open when I click on a download link on a web page.How to make the download manager know it is a link to a downloadable file as opposed to something like a link to another webpage?

I decided it's time to migrate from VB6 to VB.NET and am currently translating my radio player but have run into several issues so I might be on this forum for the rest of the day... Anyway, in VB6 I used Inet to get the source of a PHP page that had the current song that was playing on the SHOUTcast stream. I can't seem to get Inet to work and figured I would just look for another method so I wouldn't need to pack msinet.ocx along with the finished product.
How can I get the source of the PHP page and store it in a variable or textbox/label.
have been having. Basically what i am trying to do is grab an element off a WebPage by it's class name and make Vb automatically look up to see if there is a number greater than with in the element. I have the html code below.

View 2 RepliesI can now navigate to pages, fill forms, submit forms, click elements etc.My next big step will be collecting html element ID's which are constantly different each time I navigate to a page.On the webpage I am working on, each page contains 10 of these ID's.
ill_btn_20234518
ill_btn_20534538
ill_btn_20174048
Now I am just looking to click on one of them at random for right now. It doesn't matter which one. Or perhaps the first one to appear on the webpage.Here is the code that I tried first........it works fine for clicking static buttons (without the random id #'s at the end)
Dim ill As HtmlElement = WebBrowser1.Document.GetElementById("ill_btn_")
ill.InvokeMember("click")
End Sub
I guess what I am looking for here is some sort of partial id tag, to let it know to search for the first ID that begins with ill_btn_ ?

View 1 RepliesI have been given an ASP.Net assignment at work because I had taken a few courses a couple of years ago. Currently, there are no ASP.Net programmers for me to ask here and I have searched several places (including Pro ASP Net book) to find a solution but have come up empty handed.
I have a class named spErrors which takes the values passed to it. Values passed include the offending page,function/sub, and other values and stores them in property values, then calls Response.Redirect("Errors.aspx") from the page's code behind page. In Errors.aspx, the values of the error/exception trapped in the Catch statement are displayed. This works fine from a web form. My question is, how do I call a web page from a class module?
Each class module has the ErrorHandler() procedure that passes these values to the class object. In the class, there is a Write Only property named Redirect and a method called Execute() which is used to display the error page if the error occurs in another class module. Since Response.Redirect() does not work in a class module, what namespace is needed in order for this to work?
Here is the code I'm using.
In the Catch block.
Catch ex As Exception
Err.Description = ex.Message
ErrorHandler(Err, "function name")

I am writing a Windows Service to act as an internal Web image collector. I can thumbnail Web navigated to webpages using a webBrowser Control. But since a Service will not support a UI based Control like a WebBrowser control I have switched gears using the wrapper WebClient from system.net. So I am looking for a way to capture and thumbnail a Webpage.I can use the following to grab images off a web pager using webClient but cannot figure out how to thumbnail the entire page.
Dim imgBuffer() As Byte Using wclient As New WebClient() imgBuffer = wclient.DownloadData("http:// Webpage/Image") End Using
Using mem As New IO.MemoryStream(imgBuffer) Using img As Image = Image.FromStream(mem) Me.PictureBox1.Image = img.GetThumbnailImage(100, 100, Nothing, IntPtr.Zero) End Using End Using

I am trying to automate file downloads. Sometimes I get to a webpage that has a file link to download a file, but it is not a direct link. Instead it is a PHP request on the server side, for the file.
Is it possible to automate this using the webbrowser control, or is there another way I can do this using VB .NET?
I'm just wondering, how do i make a class link into my main code, it is in the same project so no need to reference it

I'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)
.Dll:
Code:
Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer
Function SetData(Data As Integer)
end interface
[code]....
this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.
I have a link here that works perfect for calling the postback close that I need to happen:
<a href="javascript:parent.__doPostBack('Close','')"><asp:Label ID="Label5" runat="server" Text="Close Me"></asp:Label></a>
However, I would like to be able to call the *javascript:parent.__doPostBack('Close','')* method from the code-behind file rather than the user clicking the link. I.e., when I have completed my tasks in the application code, call parent.doPostBack as my last function call, which closes the window in question.
