.NET/Java PDF, Tiff, Barcode SDK Libraryou already know from your work with ASP .NET that the Page object is your base class for all ASP.NET pages. You re probably familiar with the event life cycle of the Page object, at least the Load event and control-specific events that execute when a postback occurs. In this chapter we re going to pull back the covers on System.Web.UI.Page. We ll examine the pieces and parts of its infrastructure that allow you to interact programmatically with control objects, while still sending a stream of HTML back to the client. Sometimes the layer of abstraction between you and the stream of HTML going to the client can be frustrating. There are times you ll want to have specific control over the HTML that you re generating, and the Web Control just won t be generating the HTML quite the way you d like it to. The good news is there s nothing stopping you from exercising exactly as much control over the generated HTML as you need. With a thorough understanding of the work that the Page object does, the structure and touch-points of its control tree, and how the rendering process accomplishes its work, you have a toolset to help you greatly increase your control over the generated HTML. The Page object orchestrates the entire construction of the web page. It houses the process life cycle, the event infrastructure, and the hierarchical control tree that generates the page s HTML. In this chapter, we ll drill into these internal components of the pageprocessing infrastructure. barcode add-in for excel free download, how to print barcode in excel 2007, excel2010 microsoft barcode control 9.0, convert text to barcode in excel 2003, barcode font excel 2010 free, excel barcode add-in 2007, free barcode add in for excel 2010, how to create barcode in microsoft excel 2003, excel barcode font 2010, barcode add in for microsoft excel 2007,Note The RAW data type stores data that is not to be interpreted (i.e., not explicitly converted when moving data between different systems) by the Oracle database. These data types are intended for binary data or byte strings. { comment lexbuf; token lexbuf } { STRING (string lexbuf.StartPos "" lexbuf) } GET_RAW: This function reads a RAW value from a file and adjusts the file pointer ahead by the number of bytes read. It ignores line terminators and returns the actual number of bytes requested by the len parameter. The syntax is UTL_FILE.GET_RAW (fid IN utl_file.file_type, r OUT NOCOPY RAW,len IN PLS_INTEGER DEFAULT NULL); The Page object s fully qualified name is System.Web.UI.Page. In the last chapter you saw how this type is an implementation of the IHttpHandler interface, and it simply plugs into the ASP.NET request processing pipeline. Now take a closer look at the object graph of this particular handler, which is shown in Figure 3-1. This object graph applies to Web Forms, as long as you leverage the code-behind model. When no code-behind is used, the code-behind page object is removed from the graph; in this case, the markup contains the code in server-side script blocks. In version 2.0 of the .NET Framework, a new Web Form model that supports a partial classes feature is baked into both C# and VB .NET. Partial classes introduce a number of subtleties into the structure of a Web Form that warrant a closer examination. and comment = parse | "(*" { comment lexbuf; comment lexbuf } | "*)" { () } | "\n" { lexbufEndPos <- lexbufEndPosNextLine; comment lexbuf } | eof { failwith "Unterminated comment" } | _ { comment lexbuf } and string pos s = parse | "\\" ('"' | 'n' | 'r' | 't') { let s' = s + (match Lexinglexeme lexbuf with | "\\\"" -> "\"" | "\\n" -> "\n" | "\\r" -> "\r" | "\\t" -> "\t" | "\\\\" -> "\\" | _ -> "") in string pos s' lexbuf } | "\"" { s } | "\n" { lexbufEndPos <- lexbufEndPosNextLine; string pos (s + "\n") lexbuf } | eof { failwithf "end of file in string started at or near %A" pos } | _ { string pos (s + (Lexing.
