Excel 获取两个VBA文本框以一起滚动
我有一个宏,它可以生成两个包含相关数据的多行文本框(有时长达数百行)。框中的文本行数始终相同,每一行对应于另一个文本框中的相邻行。我考虑使用两列列表框,但决定使用文本框,以便用户可以根据需要复制/突出显示/选择数据Excel 获取两个VBA文本框以一起滚动,excel,vba,textbox,scrollbar,userform,Excel,Vba,Textbox,Scrollbar,Userform,我有一个宏,它可以生成两个包含相关数据的多行文本框(有时长达数百行)。框中的文本行数始终相同,每一行对应于另一个文本框中的相邻行。我考虑使用两列列表框,但决定使用文本框,以便用户可以根据需要复制/突出显示/选择数据 我希望这样,如果用户向下滚动,两个文本框一起滚动(即,行保持同步) 经过大量的挖掘和实验,我终于找到了答案!通过添加滚动条,我可以使用ScrollBar\u Change()事件来调整文本框。在我的表单上,我现在有两个文本框和一个滚动条对象。然后,我的Userform代码中有一些必要

ScrollBar\u Change()
事件来调整文本框。在我的表单上,我现在有两个文本框和一个滚动条对象。然后,我的Userform代码中有一些必要的sub:
'This constant affects whether the ScrollBar appears or _
not, as well as some of the movement graphics of the _
ScrollBar.
'This MUST be reset if the TextBoxes are resized
'I made it a UserForm-level Const because I use it _
elsewhere, but it could also live in SetUpScrollBar
Private Const TEXTBOX_MAX_LINES_IN_VIEW as Long = 21
Private Sub SetUpScrollBar()
'I call this whenever I show my Userform (happens after a _
separate macro determines what to put in the TextBoxes). _
It determines whether the ScrollBar should be shown, and _
if so, sets the .Max property so it scrolls in accordance _
to the number of lines in the TextBoxes.
Dim linesInTextBox as Long
With Me.TextBox1
.SetFocus
linesInTextBox = .LineCount - 1
'Need to subtract 1 or you'll get an error _
when dragging the scroll bar all the way down.
End With
'If there are fewer lines than the max viewing area, hide the scroll bar.
Select Case linesInTextBox > TEXTBOX_MAX_LINES_IN_VIEW
Case is = True
ShowScrollBar True
With Me.ScrollBox
.Min = 0 'I believe this is the default, but I set it just in case
.Max = maxLinesInTextBox
.Value = 0
End With
Case is = False
ShowScrollBar False
End Select
End Sub
Private Sub ShowScrollBar(show As Boolean)
'A simple way of showing or hiding the scrollbar
With Me.ScrollBar1
.Enabled = show
.Visible = show
End With
End Sub
Private Sub ScrollBar1_Change()
'When the scrollbar position changes (either by dragging _
the slider or by clicking it), set the CurLine property _
of each TextBox to the current ScrollBar value.
With Me.TextBox1
'Need to set focus to the box to get or adjust the CurLine property
.SetFocus
.CurLine = Me.ScrollBar1.value
End With
With Me.TextBox2
'Need to set focus to the box to get or adjust the CurLine property
.SetFocus
.CurLine = Me.ScrollBar1.value
End With
End Sub
这对我来说似乎很有效。它允许我在保持数据同步的同时,保持使用文本框的文本选择/复制优势
一些我尚未解决的问题:
- 滚动可以很好地工作,但是如果您尝试单击箭头(特别是指向刚刚滚动的相反方向),则必须单击箭头,直到光标到达文本框的顶部。对我来说,这是21次点击。有点烦人,但我肯定有解决办法
- 滚动与普通滚动条不同。这意味着您可以拖动滚动条,但它不会更新文本框,直到您放手
- 如果用户点击文本框并开始使用箭头键导航,这两个框将不同步。下次用户单击滚动条时,它们将重新同步。如果用户尝试选择的行数超过窗口中可见的行数,则会出现问题:一个文本框将在拖动其选择时滚动,而另一个文本框保持不变
