我的 Excel 用户表单中有 60 个文本框。为了限制用户仅在 TextBox1 到 TextBox50 中输入数字(十进制),我需要编写大量如下相同的代码。
我的问题:
1.我想创建一个类/函数,就好像我不需要为 TextBox1 到 TextBox50 编写相同的代码一样。有简单的解决办法吗?
2.如果我想限制用户在用户表单的所有文本框中输入数字。
Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
If (KeyAscii > 47 And KeyAscii < 58) Or KeyAscii = 46 Then
KeyAscii = KeyAscii
Else
KeyAscii = 0
End If
End Sub
Private Sub TextBox2_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
'same code
End Sub
.......
.......
请尝试下一个方法:
Option Explicit
Public WithEvents txtBEvent As MSForms.TextBox
Private Sub txtBEvent_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
If (KeyAscii > 47 And KeyAscii < 58) Or KeyAscii = 46 Then
KeyAscii = KeyAscii
Else
KeyAscii = 0
End If
End Sub
Option Explicit
Private txtB() As New TxtBClass
Sub AssignTxtBoxEvent()
Dim ws As Worksheet, k As Long, oObj As OLEObject
Set ws = ActiveSheet 'use here your necessary sheet
ReDim txtB(100) 'maximum text boxes to be processed (can be increased)
For Each oObj In ws.OLEObjects
If TypeName(oObj.Object) = "TextBox" Then
'exclude the textboxes you need to be excluded from this common event:
If (oObj.Name <> "TextBoxX") And (oObj.Name <> "TextBoxX") Then
Set txtB(k).txtBEvent = oObj.Object: k = k + 1
End If
End If
Next
ReDim Preserve txtB(k - 1)
End Sub
Sub
,以便在工作表上的所有文本框上分配事件。它也可以由事件调用(或者更好)。例如,使用 Worksheet_Activate
事件。请复制工作表中的下一个代码,保留文本框,代码模块:Option Explicit
Private Sub Worksheet_Activate()
AssignTxtBoxEvent
End Sub
已编辑:
为了对用户窗体中文本框的情况使用建议的解决方案,请保留相同的类,但将其事件分配给
UserForm_Initialize
事件内涉及的文本框:
Option Explicit
Private txtB() As New TxtBClass
Private Sub UserForm_Initialize()
Dim k As Long, oObj As Control
ReDim txtB(100) 'maximum text boxes to be processed (it can be increased)
For Each oObj In Me.Controls
If TypeName(oObj) = "TextBox" Then
'exclude the textboxes you need to be excluded from this common event:
If (oObj.Name <> "TextBoxX") And (oObj.Name <> "TextBoxY") Then
Set txtB(k).txtBEvent = oObj: k = k + 1
End If
End If
Next
ReDim Preserve txtB(k - 1)
End Sub
请测试它并发送一些反馈。如果今年的话,将不胜感激...
