鼠标滚动在用户窗体中不起作用 VBA

Question

我创建了用户窗体，它的高度超过了可以在显示器上显示的高度。我想准备我的用户表单更“用户友好”

身高：612
KeepScrollBarsVisable - 0 - fmScrollBarsNone
滚动条 - 2 - fmScrollBarsVerdical
ScrollHeight: 1100（如果我增加这个数字，显示 space (身高)也多)
ScrollTop 和 Left: 0
顶部：0
Excel 2016.

为什么我不能使用鼠标滚动上下滚动表单？只有单击左侧滚动框才能显示更多内容。顺便提一句。此滚动框由 ScrollBars 属性自动添加。

你能支持我吗，怎么了？谢谢

Answer 1

用户表单本身不支持鼠标滚轮滚动 (AFAIK)

我 post 代码在这里，所以 64 位答案可用。

基于this answer

步骤：

1- 在用户窗体后面添加此代码：

Private Sub UserForm_Initialize() 
    HookFormScroll Me 
End Sub 
 
 
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer) 
    UnhookFormScroll 
End Sub

2-根据your office architecture

将以下内容之一添加到Module

Answer 2

VBA 用户窗体（旧 Thunderframe）的 Window 不处理任何鼠标消息。您可以使用 Spy++ 快速测试它。不过鼠标是可以挂的

虽然@RicardoDiaz 提供了一个示例，但我应该提到他的钩子是全局的，这意味着您正在跨所有进程的所有线程跟踪鼠标消息。真的很慢而且看起来不流畅。相反，您可以使用本地挂钩（仅限本地线程）。

您可以使用我的存储库 VBA UserForm MouseScroll 中的代码，它适用于 x32 和 x64 版本。它还会滚动表单、框架、组合框、列表框等。也支持水平滚动和缩放。享受吧！
