2 談談 PowerBuilder 的開發產能 Deborah Kurata's (MSMVP) Blog Post: Painting on the DataGridView 2 Sybase ASE15 August 27, 2010

3 Deborah Kurata s Blog 的部份例子 In C#: private void mygrid_rowpostpaint(object sender, DataGridViewRowPostPaintEventArgs e) { if (e.rowindex == 2) { int rowheaderwidth = mygrid.rowheadersvisible mygrid.rowheaderswidth : 0; Rectangle rowbounds = new Rectangle( mygrid.rowheaderswidth, e.rowbounds.top, mygrid.columns.getcolumnswidth( DataGridViewElementStates.Visible) - mygrid.horizontalscrollingoffset + 1, e.rowbounds.height); ControlPaint.DrawBorder(e.Graphics, rowbounds, Color.Red, ButtonBorderStyle.Solid); mygrid.rows[e.rowindex].defaultcellstyle.backcolor = Color.BlanchedAlmond; } } 3 Sybase ASE15 August 27, 2010

29 Windows Communication Service(WCF) WCF 是微軟下一世代開發分散式應用程式的技術 WCF 可以利用 Web Service 與其它支援 SOAP 的不同平台進行溝通, 例如 :Java 2 / J2EE 等 WCF 提供低階非同步來處理早期非型別的訊息 而在最上層是更高階的服務, 包含型別訊息, 安全性訊息交換, 穩定性訊息交換, 交易訊息及佇列訊息 29 Sybase ASE15 August 27, 2010

30 WCF Client Support WCF Client is an engine to be used (in PB12 WPF target) to consume several kinds of services: ASMX Web Services ASMX + WSE 3.0 Services WCF Services ASMX Web Services WCF Engine 2 ASMX Web Services + WSE Web Service Engine (EasySoap,.NET Engine) WCF Services (basichttp, wshttp, nettcp, REST) Aug-10 Sybase ASE15 August 27,

31 Windows Presentation Foundation WPF 全名為 Windows Presentation Foundation, 是微軟力挺的下一代圖型操作介面技術 31 Sybase ASE15 August 27, 2010

32 WPF Feature and Advantage 1. 支援硬體加速 2. 解析度獨立 3. 介面描述語言 (XAML) 4. 以物件為基礎的繪圖 5. 解除控制元件外觀限定 6. 統合 2D/3D/ 影片 7. 時間軸為基礎影格動畫 8. 資料繫結 32 Sybase ASE15 August 27, 2010

33 XAML and WPF is good, but 了解 XAML 以及使用 XAML 不容易 在.NET Framework 3.0 中扮演非常重要的角色 經常被使用於 WPF 應用程式 Silverlight 以及 WF(Windows Workflow Foundation) 使用 WPF 開發資料導向程式不容易 需透過 XAML 定義各種使用者介面的元件, 諸如按鈕 表單或排版等等 需透過 XAML 繫結資料, 如文字檔 多媒體影音 WPF 提供義事件驅動, 如滑鼠點擊 滑鼠拖曳等等, 但因為採用以 XML 為基礎的排版方式, 設計變得更加開放但難度高 33 Sybase ASE15 August 27, 2010

34 PowerBuilder.NET for WPF Development and more Benefits for WPF Application Targets.NET Assembly Targets.NET Web Service Targets 34 Sybase ASE15 August 27, 2010

35 PowerBuilder: A Full.NET Citizen An effective illustration that PowerBuilder, and the PowerBuilder Developer, are full.net citizens......they are utilizing the same tools and the same off the street... XAML Control Templates Skins 3 rd party controls...as non-powerbuilder.net developers 35 Sybase ASE15 August 27, 2010

36 PowerBuilder: A Full.NET Citizen XAML XAML 是標籤語言 XML 的一種, 用來建立複雜的 WPF 使用者介面 36 Sybase ASE15 August 27, 2010

37 PowerBuilder: A Full.NET Citizen Control Templates Are described by a portion of XAML Act as resource dictionaries Specify to what kind of control they may be applied Alter the default appearance of the designated WPF control 37 Sybase ASE15 August 27, 2010

38 PowerBuilder: A Full.NET Citizen Control Templates May certainly be used with controls in PowerBuilder.NET in that they are derived from base WPF classes <pbwpf:commandbutton.template> <ControlTemplate TargetType="{x:Type pbwpf:commandbutton}"> <Grid Margin="5"> <Ellipse Stroke="DarkBlue" StrokeThickness="2">... </Ellipse>... </Grid> </ControlTemplate> </pbwpf:commandbutton.template> 38 Sybase ASE15 August 27, 2010

39 PowerBuilder: A Full.NET Citizen Control Templates (cont d) 39 Sybase ASE15 August 27, 2010

40 PowerBuilder: A Full.NET Citizen Skins Are also declaratively developed in XAML Can be statically or dynamically invoked Have a wider scope than control templates Alter appearance (as well as behavior!) of not just controls or groups of controls, but for an entire application if you wish 40 Sybase ASE15 August 27, 2010

41 PowerBuilder: A Full.NET Citizen Skins (cont d) May be used with WPF PowerBuilder applications after you... Develop them yourself Find those that are freely available Purchase those that are professionally developed Off the street skins will need to be slightly modified to utilize PowerBuilder WPF subclasses 41 Sybase ASE15 August 27, 2010

42 PowerBuilder: A Full.NET Citizen Skins (cont d) 42 Sybase ASE15 August 27, 2010

45 PowerBuilder: A Full.NET Citizen 3 rd Party WPF Controls May be used with WPF PowerBuilder applications after you... Use base WPF controls You or your teammates develop them in VS Find those that are freely available Purchase those that are professionally developed 45 Sybase ASE15 August 27, 2010

50 Powerscript language enhancements PrimitiveType Mapping System.Object Arrays Parameterized Constructors User-defined Enumerations Properties & Indexers Interfaces Generics Delegates Namespace Bitwise Operators 50 Sybase ASE15 August 27, 2010

51 Primitive Type Mapping 51 Sybase ASE15 August 27, 2010

52 System.Object.NET root type PowerObject inherits from System.Object Any PowerBuilder type can assign to each other with system.object System.Object o Int i = 1 o = i.net functions of System.Object can be invoked in PowerBuilder PowerObject po po = create powerobject po.tostring() 52 Sybase ASE15 August 27, 2010

53 Parameterized Constructors Define parameterized constructor event for NVO E.g. global type nvo from nonvisualobject event type long constructor(string s1, string s2) end type Create object with parameterized constructor event nvo nvo1 nvo1 = create( s1, s2 ) 53 Sybase ASE15 August 27, 2010

54 Parameterized Constructors (Continued ) Constructor events rules: Invoking ancestor s constructor event must be the first statement of descendant s constructor event Super::EVENT constructor( s1, s2) Default constructor is defined, optional to invoke any ancestor s constructor event Default constructor is not but parameterized constructor events are, mandatory to invoke ancestor s constructor event 54 Sybase ASE15 August 27, 2010

55 User-defined Enumerations Original PowerBuilder system-defined enumerations Encoding{EncodingANSI,EncodingUTF16E,EncodingUTF8,EncodingUTF16BE} Global user-defined enumerations E.g. global type myenum enumerated Item1, Item2 End type Local user-defined enumerations in scriptable objects [NamespaceName.][enumerationName.]enumeratione ntryname! E.g. myenum.item1!, encoding.encodingansi! 55 Sybase ASE15 August 27, 2010

56 Interfaces Define interface E.g. global type myinterface from myinterfacebase function string f(int i) int p[get,set] event type int e() string this[int i, int j][get,set] end type Implement interface: Custom Class, Standard Class, Custom Visual, Standard Visual, Window, Menu E.g. global type nvo from nvovisualobject, myinterface event type int myinterface.e() public int myinterface.p[get, set] public string myinterface.this[int i, int j][get,set] end type forward prototypes public function integer interface1.f1 (int i) public function int interface1.p_get () public subroutine interface1.p_set (int value) public function string interface1.this_get (int i, int j) public subroutine interface1.this_set (string value, int i, int j) end prototypes 56 Sybase ASE15 August 27, 2010

57 Namespace These objects can specify namespaces: Custom Class, Standard Class, Custom Visual, Standard Visual, Window, Menu, Structure, Function, Interface, and Enum namspace namespace a.b using system.text end namespace Two ways to identify a unique name Full qualified name, System.Collections.Generic.Dictionary<long, int> Use using directive Namespace searching sequence Current namespace Identifiers without namespace Namespace specified in using directive The searching sequence for a variable Argument or local variable Shared variable Global variable (follow searching sequence of namespace) Instance variable 57 Sybase ASE15 August 27, 2010
