How can I get the handle to the client part of IE

Hi all,

Looking for a way that from a program I can (a) open an instance of IE and (b) get the handle to the "client part" of that open IE web browser.  The client part is the area in which the web page is rendered.

Would like to understand how to do this in either VB.NET or C#.NET.

Can anyone help ?

Thanks,

John

Hi,
in case you need some sample code how to get the client area: you can just use FindWindowEx again:

Dim ClientArea as Long
ClientArea = 0

 'You found the Handle, saved in IEWindowHandle
FindWindowEx(IEWindowHandle, 0, "Shell DocObject View", "")

Explanations:
This is the declaration of FindWindowEx:

FindWindowEx(HWND hwndParent, HWND hwndChildAfter, LPCTSTR lpszClass, LPCTSTR lpszWindow)

hwndParent: the IEWindowHandle we found above
hwndChildAfter: search all Windows within the IE Dialog
lpszClass: The class of the Windows, as you see above it is "Shell DocObject View". You can find out things like this using the Spy++ tool of Microsoft, which is includid in Visual Studio 6. (If you dont have it, download "spyxx.exe", "spyhk55.dll" and "spyxx.hlp" from http://www.et.utt.ro/public/ProgLangs/VisualStudio6/common/tools/ )
lpszWindow: Window's Caption. According to Spy++ the Caption of the Client Area is ""

Hope you'll get it to work

Hmm. Don't know VB that well, but you could do something like this:

x = CreateObject("InternetExplorer.Application")

x.document.body = "<html><head>From VB</head><body>Hello VB COM world</body></html>"

messagebox "Click OK to close"

Does that work?

No.  But thank you for taking time to respons.

I'm looking to get the actual window "handle" (unique window identifier in the OS for each window and control created...and it's an integer) to the part of the browser that renders the web page for something else I need to do.

Thanks,

John

Hi,
all you ned is the Windows Caption and an API Function:

---------------------------------------------------------------------------------------------
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hwndParent As Long, ByVal hwndChildAfter As Long, ByVal pszClass As String, ByVal lpszWindow As String) As Long

Dim IEWindowHandle As Long, IECaption as String
IEWindowHandle  = 0
IECaption = "Google - Microsoft Internet Explorer" 'Must be exact

IEWindowHandle = FindWindowEx(IEWindowHandle , 0, vbNullString, IECaption)
If IEWindowHandle = 0 Then
   'Error handling
Else
   'You found the Handle, saved in IEWindowHandle
End If
---------------------------------------------------------------------------------------------
and by the way .... a windows handle has always 'Long' datatype

good luck

Try This:

Reference Microsoft Internet Controls

Dim IE As InternetExplorer
Set IE = New InternetExplorer
IE.Navigate2 "www.google.com"
IE.Visible = True
MsgBox IE.hWnd

Here is are some links to microsoft that may be useful.

My Spy++ shows the class of the client area is "Internet Explorer_Server" and the title blank.

@adq: Mine too, as Child of "Shell DocObject View"
@John: Depending on what you are planning to do: trial and error with the classes
