DCU2PAS非常不错的破解控件程序,一定要尝试一下啊!

Project   Dcu2Pas Version 1.3
Purpose   Decompile a D2-D7, K1-K3's dcu(dpu) file to Delphi source as origin as
          possible, without or with minimal modifications, then recompile to new
          one under other Delphi versions

          FOR RESTORE YOUR LOST SOURCES AND OPTIMIZE YOUR CODES ONLY!!!

--------------------------------------------------------------------------------

This project is in very early stage, no document yet. To see some features, 
reference my test cases file -- test.pas and the output file test.int, please.
The output maybe more clear organised than source files!!!

For further development, any suggestions and ideas are welcome. I have no time
to update my homepages for a long time ;-)

--------------------------------------------------------------------------------

Usage

Run Dcu2pas, set properly options, select a desired dcu file double click to
decompile it

Features
  - Supports the following type declarations and their typed consts:
    * Type redeclarations, for example:
        type
          MyTypeString = type String;
    * All integer types(Byte, Cardinal, Int64, Integer, Longint, Longword,
      Shortint, Smallint, Word)
    * All char types(AnsiChar, Char, WideChar)
    * All boolean types(Boolean, ByteBool, LongBool, WordBool)
    * Enumerated type, subrange of enumerated type and set of enumerated type
      For examples:
        type
          Size = (Small = 5, Medium = 10, Large = Small + Medium);
          TMySize = Medium..Large;
        type
          TEnumSet = set of (Club, Diamond, Heart, Spade);
        const
          vcSet4: TEnumSet = [Club,Spade];
    * All real types(Comp, Currency, Double, Extended, Real, Real48, Single)
    * All string types(AnsiString, ShortString, String, String[XX], WideString)
    * Array type(with/without packed keyword), dynamic array and
      multidimensional dynamic array
    * Set type
    * Record type, with any variant parts in records. But if a record has any
      variant parts in it, the typed const may can't correctly decompile
    * Function/procedure type declaration
  - Support threadvar
  - Support resourcestring
  - Support class type, interface inheritation
  - Support object type
  - Support interface
  - Code decompiler to BASM, then a decpompiled file can recompile under other
    Delphi versions...
  - Code decompiler to Object-Pascal. I have some ideas, but I have no time,
    maybe in near future, I will code for it!
