滚动条移动 SetScrollPos 和 SendMessage

发布于 2024-09-10 02:43:20 字数 437 浏览 3 评论 0原文

我正在尝试以编程方式移动窗口的滚动条。我首先发送 :，

SetScrollPos(handle, 1, position, true);

然后发送 :

SendMessage(handle, 0x0115, wparam, new IntPtr(0));

wparam 是正确的。当我通过spy++检查时，使用上述代码发送滚动和实际滚动之间的唯一区别是，在实际滚动中，消息嵌套级别为1，但这里为0。但除此之外，所有其他属性都相同，WM_VSCROLL、句柄、位置、wparam 等。但是编程滚动不会移动栏。关于我做错了什么有什么建议吗？？？

PS：尝试从 ac# 应用程序执行此操作非常感谢！

编辑：当我将 SB_BOTTOM 传递给 wparam 时，它会将我正确地带到滚动的末尾。

I'm trying to move the scrollbar of a window programatically. I'm first sending a :

SetScrollPos(handle, 1, position, true);

and then followed by :

SendMessage(handle, 0x0115, wparam, new IntPtr(0));

The wparam is correct. When i inspect through spy++, the only difference between sending a scroll with the above code and actually scrolling is that in the actual scroll, the message nesting level is 1 but here it is zero. But that apart, all the other properties and same, the WM_VSCROLL, handle, position, wparam etc. But the programatic scroll doesn't move the bar.
Any suggestions on what im doing wrong???

P.S: Trying to do this from a c# application
THanks a ton!

EDIT: when i pass SB_BOTTOM to the wparam, it takes me correctly to the end of the scroll.
