Get Webpage Source With WinInet?

Nov 6, 2010

I know that .NET has several classes to do that, but sometimes I need to download a webpage that requires login, like a forum. I do not want users to fill in their sername/password in my application, because I know I'll get a lot of complaints about that. WinInet handles cookies automatically (if the user is logged in with Internet Explorer), but WebClient, HttpWebRequest and WebRequest don't.In my VB6 application I show a messagebox, telling the user that the webpage can't be downloaded the 'normal' way, but if they want, that the application can still download the webpage if they are logged in with IE.This is the VB6 code slightly modified. It works fine until it gets to the line:

vb.net
iResult = InternetReadFile(hInternet, sBuffer, BUFFER_LEN, lReturn)
I think something is wrong with the InternetReadFile declaration.

Viewing Source Of A Webpage?

Mar 24, 2010

Been working on a Web Browser in VB 2008 Express, and so far things have been going good. I have run into a little problem though. I have a menu bar at the top of the browser as normal and one of the items selects is "View" and then under that "Page Source".

Now, i have added the following code and it works as expected but one problem. When the box opens to display the web page source it has no scroll bars, minimize or maximize buttons to manipulate the page.

Private Sub PageSourceToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PageSourceToolStripMenuItem.Click
Dim pagelSource As String = WebBrowser1.DocumentText
MsgBox(Me.WebBrowser1.DocumentText)
End Sub

I think the problem is that I am using "MsgBox" . Would there be a better way to do this?

I have to extract the page source of a webpage which I can do so like this:

The above code works fine on most of the websites I have tried to extract page source from but for some reason it is failing to extract the html contents of few websites like these where the message posted by a user is nowhere to be seen? The webpage in question is this: [URL]

Is there something I have missed or is it due to forum protection etc which is preventing the vb application from extracting the whole page source?

Incomplete Webpage Source Returned?

Nov 19, 2009

I am working on an app that requires searching the source code for a printer's web page for some information. I have used several methods to retrieve the source code (WebClient.DownloadString, HttpWebRequest.GetResponse) and in all cases recover only a portion of the web page. I can use View Source on the webpage and it is a 14K file, but using the VB functions I only get 5K of it. In these cases the data stops just prior to a <div class="tabBox"> tag containing data specific to the printer. I have also added code to pause the app, thinking that maybe it needed time for the page to complete before returning the code. Any ideas what I need to do to get the whole page?

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.

Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.

C# - Add A Reference To Some Source Code To Include In A Source File In .net, Winforms?

Jan 26, 2010

I don't know what this is called so I've struggled to find an answer from google but I have a vague memory of it from t'old days.I've sub-classed (* see below) about 8 framework controls, overriden some properties and added some functionality into each one.The changes I have made are identical in every case. If I make a change, I have to go through each class and apply the same change there.I was hoping there may be a keyword such as <IncludeSourcefile "common.vb> that I can put into each class.

(* note) I use the term sub-classed but I don't know if that's the correct terminology. I've also seen it used for call-backs. Is sub-classed the correct term to use?
