I am now on another computer.
With Windows 7 64-bit, PB 4.61 Beta 1, Firefox 11.0

Now, at first glance, it "seems" to work, because there is an output, BUT the contents is NOT of http://ip.xxoo.net/ !
Instead, it contains this:

It is not an illusion, it contains "This program cannot display the webpage".
Here is the source code:

Code: Select all

    Procedure.s GetHtmlCode(URL.s)
        GhostWin=OpenWindow(#PB_Any,0,0,600,300,"",#PB_Window_Invisible)
        WebGad=WebGadget(#PB_Any,10,10,580,280,URL.s,#PB_Web_Mozilla)
        While WindowEvent():Wend
        While GetGadgetAttribute(WebGad,#PB_Web_Busy)<>0
            While WindowEvent():Wend
        Wend
        While WindowEvent():Wend
        WebPage.s=GetGadgetItemText(WebGad,#PB_Web_HtmlCode)   
        CloseWindow(GhostWin)
        ProcedureReturn WebPage.s
    EndProcedure


    C$=GetHtmlCode("http://ip.xxoo.net")
    DeleteFile("c:/temp/xxoo.htm")
    OpenFile(1,"c:/temp/xxoo.htm")
    WriteStringN(1,C$)
    CloseFile(1)
    
    
    If OpenConsole()
        PrintN(C$)
        PrintN(Str(Len(C$)))
        Input()
    EndIf

What now??? To me, #PB_Web_HtmlCode does NOT work.
If it worked for you, please check also the contents!

What is wrong with using ReceiveHTTPFile(url, filename)?

Ok, let's try.

Code: Select all

  InitNetwork()
  
  Filename$="c:\temp\xxooinfo.htm"
  If ReceiveHTTPFile("http://ip.xxoo.net/", Filename$)
    Debug "Success"
  Else
    Debug "Failed"
  EndIf

Result:

This works. Thanks Foz!
But, it is not 100% complete.

I've noticed GetGadgetItemText(#PB_Web_HtmlCode) doesn't return everything in the webgadget. Anyone care to explain why ?

Nubcake is correct (but here we used ReceiveHTTPFile()). After comparison, we can see that this portion is missing in the file between <script> and </head>: (compared with the source code obtained with Ctrl+U in the browser)

Code: Select all

<script type="text/javascript"></script><link rel='stylesheet' type='text/css' href='/B1D671CF-E532-4481-99AA-19F420D90332/netdefender/hui/ndhui.css' /><!--[if lt IE 8]><link rel='stylesheet' type='text/css' href='/B1D671CF-E532-4481-99AA-19F420D90332/netdefender/hui/ndhui_ie7.css' /><![endif]-->

Look at the contents I posted. Works fine here. Don't know why it's failing for you. Must be either a firewall or ISP issue.

It is a real miracle that it works on your computer, dear MachineCode!

I have no clue what is happening, because xxoo is working fine when using Firefox or IE directly....

I can confirm that charvista's code example from April 14th 3:33 pm
doesn't return any HTML code for the web site "http://ip.xxoo.net"
although "http://www.purebasic.com" works just fine (tested in
Windows XP SP3). But by selecting all the text on "ip.xxoo.net" and
then reading the selected text, it is at least possible to get that text
(for example to retrieve the displayed IP address):

Code: Select all

#OLECMDID_SELECTALL = 17
#OLECMDEXECOPT_DONTPROMPTUSER = 2

Procedure.s GetText(URL.s)
  GhostWin=OpenWindow(#PB_Any,0,0,600,300,"",#PB_Window_Invisible)
  WebGad=WebGadget(#PB_Any,10,10,580,280,URL.s)
  While GetGadgetAttribute(WebGad,#PB_Web_Busy)<>0
    WindowEvent()
  Wend
  
  WebObject.IWebBrowser2 = GetWindowLong_(GadgetID(WebGad), #GWL_USERDATA)
  WebObject\ExecWB(#OLECMDID_SELECTALL, #OLECMDEXECOPT_DONTPROMPTUSER, 0, 0) 
  
  Text$=GetGadgetItemText(WebGad,#PB_Web_SelectedText)   
  CloseWindow(GhostWin)
  ProcedureReturn Text$
EndProcedure

Debug GetText("http://ip.xxoo.net")

*Sigh*, I hadn't realised that the truncating issue hadn't been resolved yet with ReceiveHTTPFile().

Until then, use http://www.purebasic.fr/english/viewtopic.php?p=217199.
