IE到底提供了多少COM服务
我要实现这样 的功能:当ie打开一个网址时,能通知我的程序,让我的程序先处理一把。
有多少给多少吧,谢谢各位了,资料越全越好(不紧紧与本问题相关的接口)
分数多啊,虽然每次我只能给100。资料告诉我哪里有下也好
真的非常感谢了

2. Using IShellWindowsClick Button1 to have the locationurls from all running instances of Internet Explorer - including open folders and Windows Explorer - shown in a listbox.uses
shdocvw_tlb;procedure TForm1.Button1Click(Sender: TObject);
var
x: Integer;
Sw: IShellWindows;
begin
sw := CoShellWindows.Create;
for x := 0 to SW.Count - 1 do
Listbox1.Items.Add((Sw.Item(x) as IWebbrowser2).LocationUrl);
end;
Sinking events from IShellWindows.DShellWindowsEvent has two events OnWindowRegistered (called when a new instance of IE is created) and OnWindowRevoked (called whel an instance of IE is closed).Drop a DShellWindowEvent-component on your form and connect it to your instance of IShellwindows:var
sw : Ishellwindows;begin
sw := CoShellWindows.Create;
DshellwindowsEvents1.Connect(sw);
end;
The following code will keep track of running instances of Internet Explorer - add or remove them from a listbox based on information from OnWindowRegistered and OnWindowRevoked uses
shdocvw_tlb;
procedure TForm1.DShellWindowsEvents1WindowRegistered(Sender: TObject;lCookie: Integer);
begin
Listbox1.Items.Add('Instance with Cookie no: '+InttoStr(lCookie));
end;procedure TForm1.DShellWindowsEvents1WindowRevoked(Sender: TObject;lCookie: Integer);
begin
Listbox1.Items.Delete(Listbox1.Items.IndexOf('Instance with Cookie no: '+InttoStr(lCookie)));
end;procedure TForm1.FormCreate(Sender: TObject);
var
sw : Ishellwindows;
begin
FormStyle:=fsStayOnTop;
sw := CoShellWindows.Create;
DshellwindowsEvents1.Connect(sw);
end;
Sending commands to a running instance of IEYou can obtain an IWebbrowser2-interface from each of the running instances listed in IShellwindows by simple typecasting if WB:=Shellwindows.Items(x) as IWebbrowser2;
The following code will close all running instances of IE when Button1 is clicked:
procedure TForm1.Button1Click(Sender: TObject);
var
x : Integer;
sw: Ishellwindows;
wb: IWebbrowser2;
begin
sw := CoShellWindows.Create;
for x := 0 to sw.count do
begin
WB := Sw.Item(x) as IWebbrowser2;
if wb<>nil then WB.Quit;
end;
end;
Sinking Events from a running instance of IE.Drop a DWebbrowserEvents2-component on your form and connect it to an instance of IE by using DWebbrowserEvents21.Connect(IE);
var
ShellWin : shdocvw_tlb.IShellWindows;
IE : IWebbrowser2;begin
IE:=shellwin.Item(Shellwin.Count-1) as IWebbrowser2;
DWebbrowserEvents21.Connect(IE);
end;
The following code opens a new instance of IE, lets it navigate and captures the statustext-change in a listbox:uses
shdocvw_tlb;procedure TForm1.Button1Click(Sender: TObject);
var
x: Olevariant;
sw: Ishellwindows;
wb: IWebbrowser2;
begin
WB := CoInternetExplorer.Create;
WB.Visible := True;
DWebbrowserEvents21.Connect(WB);
WB.Navigate('http://www.euromind.com/iedelphi', x, x, x, x);
end;procedure TForm1.DWebBrowserEvents21StatusTextChange(Sender: TObject;const Text: WideString);
begin
listbox1.items.add(text);
end;procedure TForm1.DWebBrowserEvents21Quit(Sender: TObject);
begin
DWebbrowserEvents21.DisConnect;
end;
The demo LogView demonstrates how to log events from all running instances of IE to a common log-listbox. The demo uses DWebbrowserEvents2 and ShellWindowEvents: var
ShellWin: IShellWindows; //NB!!
Connection: Integer;procedure InterfaceConnect(const Source: IUnknown; const IID: TIID;
const Sink: IUnknown; var Connection: Longint);
var
CPC: IConnectionPointContainer;
CP: IConnectionPoint;
begin
Connection := 0;
if Succeeded(Source.QueryInterface(IConnectionPointContainer, CPC)) then
if Succeeded(CPC.FindConnectionPoint(IID, CP)) then
CP.Advise(Sink, Connection);
end;
procedure TForm1.FormCreate(Sender: TObject);
var
X: Integer;
begin
ShellWin := CoShellWindows.Create;
ShellWinEvents.Connect(ShellWin);
for x := 0 to ShellWin.Count - 1 do
InterfaceConnect(ShellWin.Item(x) as IWebbrowser2, DwebbrowserEvents2, WBevents, Connection);
end;procedure TForm1.ShellWinEventsWindowRegistered(Sender: TObject; lCookie: Integer);
begin
InterfaceConnect(ShellWin.Item(ShellWin.Count - 1) as IWebbrowser2, DwebbrowserEvents2, WBevents, Connection);
end;procedure TForm1.WBEventsBeforeNavigate2(Sender: TObject;
const pDisp: IDispatch; var URL, Flags, TargetFrameName, PostData,
Headers: OleVariant; var Cancel: WordBool);
begin
listbox1.items.add(url);
end;
但如果用bcb,实际对应的也是这么几种方法:
1. BHO:我不知delphi能不能编bho,是利用com,为监视和控制ie
2. sink iE:就是以上的两种办法,其实都不多,先找到句柄,再得到接口,只不过得到句柄的方法很多罢了,还有可以安装钩子,跟踪焦点的办法来得到句柄!
