滚动条范围问题 [英] ScrollBar Range Issue

问题描述

我面临一个奇怪的问题.

我正在创建一个可滚动的图片控件.
如果图像的大小大于静态控件的大小，则只有滚动条可见.
我正在使用SetScrollInfo函数并将SCROLLINFO fmask设置为SIF_ALL，但它显示了两个滚动条.
(我发现此问题的原因是，如果设置了SIF_RANGE，则会出现两个滚动条.).

但是，如果我不选择SIF_RANGE作为属性，则滚动条会显示ok，但滚动位置不会更改.
:(

请给它一些说明，为什么会这样???

I am facing a strange problem.

I am creating one scrollable picture control.
If the size of image is greater than the static control size then only scroll bar is visible.
I am using SetScrollInfo function and set SCROLLINFO fmask to SIF_ALL but it displays the two scrollbars.
(The reason I found for this is that if SIF_RANGE is set then two scrollbars appear).

But, if I dont select the SIF_RANGE as a property then scrollbar displays ok, but position of scroll is not changed.
:(

Please please give some light on it why is it so ??
