怎么样具体实现添加属性页

[lkcs]

怎么利用Property sheet handlers实现添加自定义的属性页
常规下.exe的文件会有"常规,兼容性,安全,摘要"等信息,比如我想在上面添加一个自己的属性页:文件名.
请问怎么样实现,最好给出代码,谢谢

2楼提供的代码对检索资源得到的信息是固定的,我如何动态取得比如:文件名等信息呢?
ra.rc代码如下

#define DIALOG_1 1 //资源文件标示符
#define IDC_PUSHBUTTON1 101 //按扭标示符

DIALOG_1 DIALOG 6, 15, 161, 127
STYLE WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX
CAPTION "DIALOG_1"
FONT 8, "MS Sans Serif"
{
LTEXT "作者", -1, 9, 15, 47, 18 //比如我这要换成文件名.........
LTEXT "时间", -1, 8, 38, 44, 17
LTEXT "孙航东", -1, 79, 17, 64, 20
LTEXT "2002.04.26", -1, 80, 41, 60, 18
PUSHBUTTON "Button", IDC_PUSHBUTTON1, 79, 88, 53, 17
}
