I have a string var 'HTMLCode' that contains HTML code. I want to load this code into the browser. This is Embarcadero's code: procedure THTMLEdit.EditText(CONST HTMLCode: string); {VAR Doc: IHTMLDocument2; TempFile: string; } begin TempFile := GetTempFile('.html'); StringToFile(TempFile, HTMLCode); wbBrowser.Navigate(TempFile); Doc := GetDocument; if Doc <> NIL then Doc.Body.SetAttribute('contentEditable', 'true', 0); //crash here when I load complex html files DeleteFile(TempFile); end; It has some problems so I replaced it with this one: procedure THTMLEdit.EditText(CONST HTMLCode: string);

I'm trying to use DCEF3 TChromium as a replacement for TWebbrowser component. I downloaded the packages and installed it on my IDE (Delphi 2007). I'm testing the demo on demos\guiclient and when i try to open certain web pages, i get tons of Access Violation exceptions and my app crashes. If i'm inside Delphi, i get this exception before Delphi itself crashes : 'Assertion failure : 'item.src' in \win32scr\DBKIMPL.CPP' at line 2691' One example of a page that has this problem is www.whatsmyuseragent.com One example of a page that opens correctly is www.google.com After a lot of testing i found

My application uses a TWebBrowser that loads a webpage. The problem is, after closing the form containing the TWebBrowser, the memory used is not freed. If I open and close the form, the memory just keeps on increasing. Saw some post regarding calling SetProcessWorkingSetSize() or CoFreeUnusedLibrariesEx() to solve this issue, but I'm not sure if any of these are the correct solution. Any idea how to free the memory used by TWebBrowser? QC#106829 describes one possible cause of memory leaks with TWebBrowser.

How can I add an extra header to the request using IHTTPNegotiate? I added the interface but functions BeginningTransaction & OnResponse never get called. TNameSpaceHandler = class(TComObject, IInternetProtocol, IHttpNegotiate) ... function BeginningTransaction(szURL, szHeaders: LPCWSTR; dwReserved: DWORD; out szAdditionalHeaders: LPWSTR): HResult; stdcall; function OnResponse(dwResponseCode: DWORD; szResponseHeaders, szRequestHeaders: LPCWSTR; out szAdditionalRequestHeaders: LPWSTR): HResult; stdcall; ... end; I'm silently assuming you're intercepting traffic by both implementing

I have a TWebBrowser object which is created in runtime and used in background, that is, not visible. The problem is that events like OnDocumentComplete dont work or are not triggered in Delphi2009. Any advice? procedure TfrmMain.FormCreate(Sender: TObject); begin FWebBrowser:= TWebBrowser.Create(Self); FWebBrowser.RegisterAsBrowser:= True; FWebBrowser.OnDocumentComplete:= WhenDocIsCompleted; end; procedure TfrmMain.WhenDocIsCompleted(ASender: TObject; const pDisp: IDispatch; var URL: OleVariant); begin ShowMessage('Doc is completed!'); end; There is any difference important between Navigate

I am trying to block anything external loaded by TEmbeddedWB or TWebBrowser (or TCppWebBrowser). I would like to block anything that is loaded from Internet including images, javascript, external CSS, external [embed] or [object] or [applet] or [frame] or [iframe], executing JavaScript that can load external content etc. This problem consists of 2 parts: putting web browser into "restrict all" (except basic HTML without images) and detecting if such content exists if external content is not present ok, if it is, showing a "download bar" which after click puts web browser into "download all"
