下面是一些 C 变量类型和 Pascal 变量类型对照列表。

HWND = type LongWord (Cardinal)
HMENU = type LongWord
    所有 HANDLE 类型均是 type LongWord (Cardinal) 或 THandle
        (HICON, HBITMAP, HFONT, HBRUSH, HPEN)
BYTE = Byte
SHORT = Smallint;
INT = Integer
WORD = Word
DWORD = LongWord; (Cardinal)
LONG = Integer
LONGLONG = Int64
UINT = LongWord; (Cardinal)
ASCI null terminated string = PAnsiChar or PChar
LPSTR = PAnsiChar;
LPCTSTR = PAnsiChar;
ULONG = Cardinal;
BOOLEAN = Boolean
BOOL = LongBool
LPVOID = Pointer
PSID = Pointer
LCID = DWORD, LongWord (Cardinal)
LANGID = Word

  理解 Win32 API 帮助里面的数据类型可能会有点困惑,因为里面好几个 C 类型被作为一个 Pascal 数据类型了,比如 DWORD、UNIT、HWND、ULONG 和 LCID 类型在 Pascal 语言里都是 Cardinal 类型。更加令人困惑的是,很多 Delphi 的示例代码使用 Pascal 类型 LongWord 代替 Cardinal 类型,使用 LongInt 代替 Integer 类型。如果你觉得 C 语言数据类型难以把握,你通常可以在代码中使用 C 语言数据类型,因为这在 windows.pas 单元大部分都有这些类型的定义。比如, windows.pas 单元有如下定义: 

type
DWORD = LongWord;
UINT = LongWord;
LCID = DWORD;
ULONG = Cardinal;
