键入时在TextBox中设置数字格式 [英] Format numbers in TextBox as you type

问题描述

在键入时，是否可以通过格式化文本框(在用户窗体上)中的数字?

Is there is any way to format numbers in TextBox (on a UserForm) as you type?

通过这种方式，可以轻松查看正在输入的数字.

This way it makes easy to see what figure is being entered.

我想要的格式是:#，## 0.00

推荐答案

对于新手来说，这可能被认为是稍微高于平均水平的"高于平均水平"问题，因此我将回答这个问题:)

This could be considered a slightly "Above the Average" question in terms of difficulty for a newbie so I am going to answer this :)

VBA没有所谓的蒙版文本框"，您可以在其中将格式设置为#，## 0.00 .您只能为接受密码而做一个带遮罩的文本框，但这完全是另一回事.

VBA doesn't have what you call a Masked Text Box where you can set formats as #,##0.00. You can only do a masked textbox for accepting passwords but that is altogether a different thing.

这是我很快想到的.希望这就是你想要的吗?

Here is something I quickly came up with. Hope this is what you want?

Dim CursorPosition As Long
Dim boolSkip As Boolean
Dim countCheck As Long

Private Sub TextBox1_Change()
    '~~> This avoids refiring of the event
    If boolSkip = True Then
        boolSkip = False
        Exit Sub
    End If

    '~~> Get current cursor postion
    CursorPosition = TextBox1.SelStart
    boolSkip = True

    '~~> Format the text
    TextBox1.Text = Format(TextBox1.Text, "#,##0.00")

    '~~> Re-position the cursor
    If InStr(1, TextBox1.Text, ".") - 1 > 0 Then _
    TextBox1.SelStart = InStr(1, TextBox1.Text, ".") - 1
End Sub

通过同时包含此代码，您可以将其提升到更高的水平.这样可以确保用户仅键入数字.

You can take it to a slightly higher level by including this code as well. This ensures that the user only types numbers.

'~~> Numeric Textbox with Decimal Check
Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
    Select Case KeyAscii
        Case vbKey0 To vbKey9, vbKeyBack, vbKeyClear, vbKeyDelete, _
        vbKeyLeft, vbKeyRight, vbKeyUp, vbKeyDown, vbKeyTab
            If KeyAscii = 46 Then If InStr(1, TextBox1.Text, ".") Then KeyAscii = 0
        Case Else
            KeyAscii = 0
            Beep
    End Select
End Sub
