高人都到那里去啦?关于TPictureProperty的问题,那位牛人可以解决啊,分好商量! (200分)

下面这个控件可以编译,但在运行时虽说找不到Libhelp.dcu.各位帮帮忙啊!

libhelp.dcu 在delphi/lib目录下，use进去看看

我用的是Delphi7,搜遍硬盘都没有找到这个文件啊!
to jlutt-sadan:
你用的是什么版本呢?如果你有请发给我一份.
30452570@elong.com

我用的是delphi5，不知道7下面能不能使用，发给你先
您的信件已经成功发送到 30452570@elong.com

还是不行啊,
难到Delphi7居然犯这样的错误?我想应该有其它方法解决的吧

哦，没用过d7，sorry
