Because the C# COM component implements IDispatch among other interfaces. With this one you have an automatized component, and you don't need to know the name of the method invoked, only their number (1, 2, 3, etc) which can be found in the extra information of the component, defined with IDL language.

Thanks shouvik!

I think only containing interface information is not enough. I think it should also contain the CLSID (implementation class guid of the interface) information, right?

Or else, in client program, how could we know and pass both the IID and CLSID information to QueryInterface?

George

Might be they have some wrap over class informations written within the COM component. I actually am more like a novice when it comes to COM. Please forgive me Blush | :O

endl means "move the cursor to the next line", no matter where it appears. So your first line of code moves the cursor to the next line. Your second line of code prints "statement" and then moves the cursor to the next line.

IIRC endl will append a \n caracter to the line and call the flush function. In other words,

cout << "statement" << endl;

is the same as writing:

cout << "statement\n";
cout.flush();

Use the GetClassName() function to find the class of a control.That is if it is a edit control it returns "Edit"( WC_EDIT ).

CWnd::FromHandle
static CWnd* PASCAL FromHandle( HWND hWnd );

gives you a Cwnd pointer to the window in question ...from there i;d be looking at the help files for information about how to get pointers to child windows
