View 6 RepliesI wanted to ask you something which is bugging me for a while. I work an IT dept at a local bank and I got instructions to make an application which should retrieve some financial info from a financial banking stats page.
The webpage can be accessed through[URL] and the info can be seen in the web browser but I cannot extract them because the info is not available in the source code of the page.It seems it's generating the info dynamically using a jsquery.js file.
I was wondering if it's possible to make an app which uses some cache or something (I guess the the page is saved temporary somewhere on the disk for the current session) to retrieve that data in vb.net?

How do I convert a VB4 source code to VB10 source code?
View 3 RepliesI 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?

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.

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:
CODE:
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?
