And this is where it gets more complicated — for the first time we have to mess around with the COM stuff.
How to save the contents of the Twebbrowser to a file?
teebbrowser The decision is based on whether the document is stored locally or is on the internet. We then check to see if the celphi supports the IPersistStreamInit interface, getting a reference to the supporting object. Load accepts a stream object, but the stream it expects is a COM one that must support the IStream interface. Email Required, but never shown. If this works with password type input fields, I would not trust any app which uses an embedded web browser to communicate with Internet sites,for example doing an OAuth login.
The first thing to note is that, on non-Unicode compilers, the original version of LoadFromString is unchanged. Lines aave use a method like TMemo.
TStream ; const Encoding: I found on a newsgroup someone with a similar problem. Default ; if WebBrowser. The code was developed using Delphi 7 Professional non-Unicode and Delphi Unicode and tested with both those compilers and Delphi The protected “helper” methods will be discussed along with the public methods they service. IStream ; begin if not Assigned WebBrowser.
If twwbbrowser think Twenbrowser missed anything major, please feel free to add it to delpi code. Here’s the list I drew up:. We then save the string to the stream using the encoding provided in the Encoding parameter, prefixed by any required byte order mark.
Since the browser control supports different character encodings we need to add support for this to our code. TObject ; var Doc: If you add anything really useful, please let me know.
If Encoding is the same as the document’s encoding then calling this method is wasteful. Original XML from the webserver: A word of caution before we get started. You should call the SaveToStream overload that does not take an Encoding parameter instead.
How to load and save documents in TWebBrowser in a Delphi-like way
It then writes any required byte order mark to the stream stored in the Preamble variable delphu by the byte array. The code I’ll present here is for illustration purposes only. The simplest of these is the NagivateToLocalFile method. Boolean ; procedure NavigateToResource const Module: In contrast the overload of SaveToStream is very different. We do this by navigating to the special about: However, the character set can also be specified in HTML code.
If you use the “view source” option in the browser the XML -file will open OK without any formatting by the browser. SaveToStream ms ; ms. TStringStream ; begin StringStream: EDIT As mjn pointed out, the values of password type inputs will not be shown. Two overloaded methods are provided. Int64 ; begin Stream.
Click and change html OnCreate: TObject ; var Html: PChar ; const ResType: Load, and we’re done. TBytes ; begin MS: Document then Exit ; if WebBrowser.
Sign up using Email and Password. ProcessMessages ; until Int64 Windows. The local Pause procedure does a busy wait, polling the message queue for about 5ms at a time. In addition to providing new overloaded versions of SaveToStream and SaveToFile we must re-implement SaveToString when compiling with Unicode compilers to take account of the browser document’s encoding. When we discussed requirements we decided we needed to twdbbrowser able to specify an encoding when writing to files and streams and when reading from a string.
Sign up using Facebook. We check that the web browser control’s document object is available and bail out if not.
Both methods create the required URL for a given module, resource name and an optional resource type. So we call GetStreamEncoding to find tweebbrowser encoding used to generate the stream.
Document then begin sl: Sign up or log in Sign up using Google. Hello, For saving the internetpage loaded in the TWebbrowser-component are two properties.
