InternetExplorer.Application Code translate to IHTMLDocument2 interface code

Those, TMK, are not one in the same. IeA is an Application, whereas IeB is a document. Think of it like this:  IeA is an instance of IE. This instance has a member called "Document". This is what IeB would point to.

With IeB, you can interact with the html of the page you are viewing, but not with the application hosting the page. How did leB get assigned?

Thanks for the explaination

IeB is assigned by like below example(get by window handle)
 
hWnd = 6817178 'ie window handle
set IeB=hHndToIE(hWnd) (hHndToIE is user define funtcion )

is it possible set IeB  invisible? (I can handle the button in IeB like submit but do'nt know how to set ieb invisible)
thanks

thanks,it's a correct way to try,
since   ieB is get from hWnd
it can be use hWnd to hide the iE

if possible,can you give me the function code
 to hide in background object   from  hWnd?

Sorry, what do you mean by 'background object'? Since you have window's hWnd you can do whatever you want with it using API:
ShowWindow with SW_HIDE,SW_MINIMIZE etc (see http://msdn.microsoft.com/en-us/library/ms633548(v=vs.85).aspx)

Close window using SendMessage/PostMessage with WM_SYSCOMMAND+SC_CLOSE or with  WM_CLOSE

Enum it's children or GetParent
etc.

thanks the help,
in this situation  i mean 'background object'  hide(SW_HIDE)
using API
 ShowWindow(hWnd,SW_HIDE) is just the  solution

thanks for the Ark   and kaufmed useful help

ps:
I press the point too quickly,
if i can redo ,kaufmed can get 1/3 point
