What the Analysts Say

“Delphi developers should pay careful attention to the delivery of Borland’s new .NET IDE before any transition to Visual

Studio .NET … it has the potential to better meet the needs of developers

leveraging .NET in a multi-vendor, best-of-breed environment.”

—Mark Driver, Research Analyst, Gartner Group

.NET Support

Reuse Delphi language skills with the Microsoft .NET Framework- DCCIL compiler is first class .NET citizen generating 100% .NET

code- Build new .NET applications using the Delphi language

Migrate existing Delphi applications to .NET- VCL.NET is 100% .NET compliant component library with a high

degree of VCL compatibility- Reuse existing code

Single environment for Delphi and C# development- Octane IDE will interoperate with C#Builder IDE (or vice-versa)- Enables Delphi developers to add C# to their projects and skills

Don’t Fall Asleep!

從 Win32 的 Object Pascal 程式語 言到 .NET 的 Delphi 程式語言

Object Pascal幾乎完整的移植到 .NET中 , 除了不符合 .NET CLR/CLS規範以及存取硬體的機制

Object Pascal強化了語言機制 , 支持 .NET CLR/CLS功能 , 因此改為 Delphi語言

DFM檔案內之 Persistent資訊將以 Delphi原始碼的形式融入 .PAS檔案中

Data Type Mapping

Data Type Mapping

Extended System.Double是一個 8-byte floating-point type

Char變成 2個位元 String成為WideString

New & Improved

Unit Namespaces Qualified Identifiers Nested Types Custom Attributes Class (static) data Class properties Class static methods Records w/ Inheritance Records w/ methods Sealed classes Final methods

Multicast Events Include/Exclude events Array prop overloads “Boxing” into objects

Unit Namespaces

Access units with fully qualified idents- Uses Borland.VCL.Forms;

Delphi unit defines its own namespace- Dotted names in unit identifiers and file names

Project namespace search path- Search for unqualified unit names on namespace path- Uses Forms;- In VCL project, Forms -> Borland.VCL.Forms- In CLX project, Forms-> Borland.CLX.Forms

Project default namespace

Project Namespaces

Eliminate uses clause IFDEFs Project namespace search path

- Search for unqualified unit names on namespace path- Uses Forms;- In VCL project, Forms -> Borland.VCL.Forms- In CLX project, Forms-> Borland.CLX.Forms

Project default namespace- Unit MyControl;- VCL project: compiles to Borland.VCL.MyControl.DCU- CLX project: compiles to Borland.CLX.MyControl.DCU

Using Attributes

type[ FooAttribute(‘Hello’, 23) ]TMyClass = class

[ SpecialDataAttribute ]Fdata: Integer;[ WebMethod,

DebuggerStepThrough ]function SampleCount: Byte;

end;

開發流程

aDelphi專案 (*.dpr)

Delphi程式單元 (*.dfm)

DFM2PAS

Delphi.NET原始程式 (*.pas)

Delphi.NET專案 (*.dpr)Delphi.NET Compiler

dccil

.NET應用程式

A Win32 Sample Program

使用 DFM2PAS/Dccil

Dfm2pas PWin32Prg.dpr PNetPrg.dpr 修改 PWin32Prg.dpr dfm2pas fmMain.pas fmNetMain.pas

Dccil –v PNetPrg.dpr

A Object Pascal/Delphi Language Sample Program

TForm1 = class(TForm) Button1: TButton; Button2: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } class var iX : Integer; iY : Integer; class function GetX : Integer; static; class procedure WriteX(const iValue : Integer); static; public { Public declarations } class function GetSystemTime : String; static; class property X : Integer read GetX write WriteX; end;

A Object Pascal/Delphi Language Sample Program

class function TForm1.GetX : Integer; begin Result := TForm1.iX; end; class procedure TForm1.WriteX(const iValue : Integer); begin if (iValue <> TForm1.iX) then

TForm1.iX := iValue; end; procedure TForm1.Button1Click(Sender: TObject); begin Button1.Caption := TForm1.GetSystemTime; TForm1.X := 999; Button2.Caption := IntToStr(TForm1.X); end;

一般 Delphi 程式如何移植到 .NET

現在使用 Dfm2Pas/Dccil即可轉換大部份的一般程式

未來在 Delphi 8的 IDE中重新 Compile即可 一般的語法將轉為 Delphi語法 ,資料型態將轉為 CLR/CLS資料型態

對於Win32 API的呼叫將藉由 .NET的 InterOp呼叫

DLL/COM/COM+/ActiveX 元件和 .NET 程式

DLL/COM/COM+/ActiveX 元件和 .NET 程式

A DLL Demo- 使用 DllImport Attribute

- //[DllImport('aviPlayer.dll', CharSet=CharSet.Ansi, EntryPoint = 'PlayAVI')]

- //procedure PlayAVI(const sName : String); external;

DLL/COM/COM+/ActiveX 元件和 .NET 程式

A COM+ Demo

A COM+ Demo

function TdDemoCOM.GetSystemInfo: WideString; begin Result := 'This is COM+ Object Right now is : ' + DateToStr

(now); end;

Demo Process

Step 1先為 COM+建立 Type Library wrapper Assembly- Tlbimp PDemoCOM.dll /out:PNETDemoCOM.dll

Step 2 使用 dfm2pas轉換 Delphi Client應用程式- Dfm2pas PCOMDemo.dpr PNETCOMDemo.dpr- Dfm2pas fmMain.pas fmNETMain.pas

Step 3修改 PNETCOMDemo.dpr, fmNETMain.pas Step 4 使用 dccil

- Dccil –v –luPNETDemoCOM PNETDemoCOM.dpr

Delphi 資料庫應用程式如何移植 成 .NET 資料庫應用程式

BDE/IDAPI Midas dbExpress ADO.NET

BDE/IDAPI

Native drivers to various DataSource- Oracle, MS SQL Server, InterBase, dBase, Paradox…

在 .NET中仍然可以使用 BDE/IDAPI嗎 ?- 是的 , 但是僅限於 BDE/IDAPI最後支援的資料庫和版本

VCL.NET藉由 InterOp允許 .NET程式存取 BDE/IDAPI

Midas

Delphi 8會移植Midas- Borland.Db.CDS.DBClient- Borland.Db.CDS.DSIntf- Borland.Db.CDS.Mconnect- Borland.Db.CDS.Midas- Borland.Db.CDS.Provider- Borland.Db.CDS.TConnect

BDE/IDAPI

BDE結合Midas的範例

dbExpress

Delphi 8應該會把 dbExpress移植到 .NET中

ADO.NET

Delphi 8將可直接使用 ADO.NET存取資料- Borland.Db.ADONET.ADONETDb
