Title: Refreshing all Internet Explorer Windows?
Question: It is possible to connect to a running instance of Internet Explorer version 4.0 or later using the SHDocVw.ShellWindows collection and you can do with it whatever you want (i.e. refresh).
Answer:
The ShellWindows collection is described in the Internet Client SDK as follows: The ShellWindows object represents a collection of the open windows that belong to the shell. In fact, this collection contains references to Internet Explorer as well as other windows belonging to the shell, such as the Windows Explorer.
uses
MSHTML_TLB, SHDocVw_TLB;
procedure TForm1.Button1Click(Sender: TObject);
var
ShellWindow: IShellWindows;
WB: IWebbrowser2;
spDisp: IDispatch;
IDoc1: IHTMLDocument2;
k: Integer;
begin
// Create the shell windows interface
ShellWindow := CoShellWindows.Create;
// Walk the internet explorer windows
for k := 0 to ShellWindow.Count do
begin
// Get the interface
spDisp := ShellWindow.Item(k);
if spDisp = nil then Continue;
// QueryInterface for the IWebBrowser2
spDisp.QueryInterface(iWebBrowser2, WB);
if WB nil then
begin
// QueryInterface for the Document
WB.Document.QueryInterface(IHTMLDocument2, iDoc1);
if iDoc1 nil then
begin
WB := ShellWindow.Item(k) as IWebbrowser2;
// Call the Refresh method
// WB.Refresh;
end;
end;
end;
end;
