delphi - TEventObject & IE tabs gives fatal error -

-

After

I try the document using this code 

 : = (IWebbrowser2 PDisp). Document like IHTMLDocument2; Body: = Document Link: = Document.links; I: Start (Links.length-1) from = tmp: = (Links.item (i, 0) as iHTMLElement); Tmp.onclick: = TEventObject.Create (MyProcedure) as IDispatch; // this line end; Apart from E: Exception Show Message (E. ClassName + 'has been raised with error message:' + E. Message); End;

In the documentComplete event of an IE web browser, it works fine, but when I open a new tab, I have to face a Microsoft Internet Explorer and "error "Has to be shut down.

In the code given above // ​​the line marked with this line is the one which is creating it (I commented it and did not show this error).

Code: 

  TEventObject = class (TInterfacedObject, IDispatch) Private FOnEvent: TProcedure; Protected function GetTypeInfoCount (Calculate Out: Integer): HRESULT; Stdcall; Function GetTypeInfo (Index, LocaleID: Integer; Out TypeInfo): HRESULT; Stdcall; Function GetIDsOfNames (constant id: TGUID; name: indicator; NameCount, LocaleID: integer; DispIDs: indicator): HRESULT; Stdcall; Function implemented (DispID: Integer; Constants ID: TGUID; LocaleID: Integer; Flags: Word, Parameter; VarResult, ExcepInfo, ArgErr: Indicator): HRESULT; Stdcall public creator (Constant OnEvent Build: TProcedure); Property On Event: TPCCD FOnEvent writes FOnEvent; End; ........... Constructor TEventObject.Create (Constant Event: TPCCDure); Start the heritage; Create; FOnEvent: = OnEvent; End; Function TEventObject.GetIDsOfNames (static ID: TGUID; name: indicator; NameCount, LocaleID: integer; DispIDs: indicator): HRESULT; Start the result: = E_NOTIMPL; End; The function TEventObject.GetTypeInfo (index, locale: integer; out type interface): HRSLT; Start the result: = E_NOTIMPL; End; Function TEventObject.GetTypeInfoCount (Out Count: Integer): HRSult; Start the result: = E_NOTIMPL; End; Work in a TriviaBuild.Invoke (DispID: Integer; Integer; IID: TGUID; LocaleID: Integer; Flags: Word, Parameter; VarResult, ExcepInfo, ArgErr: Indicator): HRESULT; Start (Dispid = DISPID_VALUE) then if assigned (FOnEvent) then FOnEvent; Results: = S_OK; End and result: = E_NOTIMPL; End;

How do I work for this tab?

I found a workaround: 

  url: = annilever case (Url); If (URL = '') or (URL = 'about: blank') or (URL = 'about: tabs') then exit;

Click events that work well on those other pages are not about: tabs.

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
