以下摘自：侯捷<深入浅出MFC>
MFC和WIN32(SDK程序)共同使用的数据类型
数据类型 意义/定义
BOOL Boolean值（布尔值,不是TRUE,就是FALSE）
BSTR 32-bit字符指针
BYTE 8-bit整数，未带正负号
COLORREF 32-bit数值，代表一个颜色值
DWORD 32-bit整数，未带正负号
LONG 32-bit整数，带正负号
LPARAM 32-bit数值，作为窗口函数或CALLBACK函数的一个参数
LPCSTR 32-bit指针，指向一个常数字符串
LPSTR 32-bit指针，指向一个字符串
LPCTSTR 32-bit指针，指向一个常数字符串，此字符串可以移植到Unicode和DBMS(双字节字集)

这些数据格式英文也不难丫，
也可以开个词霸的
其实 数据格式也不是用记的 多用就熟悉了

同意楼上，在MSDN中都有说明，而且很全！
也就是楼上两位列出来的！

Data Types
This topic lists the data types most commonly used in the Microsoft Foundation Class Library. Most of the data types are exactly the same as those in the Windows Software Development Kit (SDK), while others are unique to MFC.
Commonly used Windows SDK and MFC data types are as follows:
BOOL A Boolean value.
BSTR A 32-bit character pointer.
BYTE An 8-bit integer that is not signed.
COLORREF A 32-bit value used as a color value.
DWORD A 32-bit unsigned integer or the address of a segment and its associated offset.
LONG A 32-bit signed integer.
LPARAM A 32-bit value passed as a parameter to a window procedure or callback function.
LPCSTR A 32-bit pointer to a constant character string.
LPSTR A 32-bit pointer to a character string.
LPCTSTR A 32-bit pointer to a constant character string that is portable for Unicode and DBCS.
LPTSTR A 32-bit pointer to a character string that is portable for Unicode and DBCS.
LPVOID A 32-bit pointer to an unspecified type.
LRESULT A 32-bit value returned from a window procedure or callback function.
UINT A 16-bit unsigned integer on Windows versions 3.0 and 3.1; a 32-bit unsigned integer on Win32.
WNDPROC A 32-bit pointer to a window procedure.

你在MSDN的索引中输入data type，会列出一堆关于数据类型的说明！
