WebHub Version .912 Release Notes

WebHub Changes

• TWebApp.OnBadIP event implemented. This is fully documented in the version 912 help file.

• new property: TWebOutput.ConsoleOutput enables standard output. If you set this to True, you can use the Pascal procedures write and writeln to write to the output document.

  procedure TFormHTSAMP.WebDemoAppExecute(Sender: TWebOutputApp; var
  bContinue: Boolean);
  begin
    inherited;
    with tWebApp(Sender) do
      if Command='WRITE' then
      with WebOutput do begin
        ConsoleOutput:=true;  //insure that the console is available;
        Command:='';
        //create an entire page using standard output.
        //note the HtmlTitle and HtmlFooter functions to structure the page.
        Open;   //actually happens implicitly on the first write.
        write(HtmlTitle('Hello There'),'Hello ',1234,' ',12345.678:10:2,'<br>');
        writeln('Testing!','<br>',HtmlFooter);
        Close;  //close the page to signal that we're done.
        end;
  end;
  

• added
  • TWebLink.OnSetState TNotifyevent
  • TWebMail.CharSet String (us-ascii)
  • TWebMail.ContentType String (text/plain)

• changed TWebMail.mailHost.Host to mailhost.hostname

• New Telnet component is available to people who have licensed the websock source bundle.

• AOL comptibility: replaced property HTTPcolon (in .911 only) with HttpUpper. This allows you to send the HTTP header using non standard lowercase http/1.0: Set this to FALSE to cause JUMPs, etc. to use lowercase http.

• TWebApp.OnExecute and OnBadIP events use parameter named bContinue now, instead of Continue.

• New functions in UcHtml for extracting HTML strings from an HTML document. These will be fully documented in the webhub help file.

• Added new TWebOutput functions. These are simple functions to return parts of a complete, correct and simple html response, leading up to a procedure to write a complete html page from a string.
  • function HtmlHeader:String;
  • function HtmlTitle(const Title:String):String;
  • function HtmlFooter:String;
  • function HtmlPage(const Title,Text:String):String;
  • procedure SendPage(const Title,Text:String);

tPack Changes

• TpList.pas.
  • Sped up stringlist assign and settext operations by overriding how memory is alloated. This speeds up operations by large amounts (90ms, not 1200) and reduces memory fragmentation (program will use 2mb, not 10mb) for stringlist operations.

  • Changed the name of the constructors for tTpStringlist and TtpCollection from 'Create' to 'Createfor'. This was done to bring the class in line with VCL standards. Owner and property are optional. The aProperty parameter is used to link to the help system and will be used as window caption when editing the stringlist in the built-in editor. Here are the new/old constructor specs:

        constructor CreateFor(aOwner:TComponent;const aProperty:String); virtual;
        constructor CreateFor(aOwner:TComponent;const aProperty:String; ItemClass:TCollectionItemClass);
    

• added tpAction.AfterExecute TNotifyEvent. This is inherited by all TWebAction components.

• retry.pas renamed to utRetry.pas
