关于多页:除非所有页面都输入,否则禁用commandbuttom2 [英] about multipage: Unless all pages have input, commandbuttom2 is disabled
问题描述
我这里有一个代码,该代码将生成页面,具体取决于文本框上的值.
I have a code here that will generate pages depends on what value is on the textbox.
'Button accepting how many number of pages
Private Sub CommandButton1_Click()
RowChar = 70
MultiPage1.Pages.Clear
For i = 0 To TextBox1.Value - 1
MultiPage1.Pages.Add
MultiPage1.Pages(i).Caption = "Variable" & i + 1
Call LabelPerPage
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "NameBox")
With txtbx
.Top = 20
.Left = 100
End With
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "MinBox")
With txtbx
.Top = 50
.Left = 100
End With
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "LsbBox")
With txtbx
.Top = 20
.Left = 300
End With
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "Mataas")
With txtbx
.Top = 50
.Left = 300
End With
If i = 0 Then
FormulaString = "= C15"
Else
FormulaString = FormulaString & " " & Chr(RowChar) & "15"
RowChar = RowChar + 3
End If
Next i
TextBox2.Value = FormulaString
End Sub
问题:如果每个页面内的所有文本框都为空,我想禁用commandbutton2(用于计算MINbox和MAxbox的按钮).您有想法怎么办?谢谢.
Problem: I want to disable commandbutton2(button for computation of MINbox and MAxbox) if all the textboxes inside each pages are empty. Do you have any IDEA how can I do that? Thank you.
推荐答案
尽管最好的方法和最简单的方法是验证@Excelosaurus回答的CommandButton2_Click
中的单击,但我只是通过以下方式提供了一些稍微修改的TextBox更改事件捕获方法: @Mathieu Guindon在帖子中的答案 . 这种封装WithEvents MSForms控件的技术的全部功劳归功于@Mathieu Guindon
Though best way and easiest way is to validate on click in CommandButton2_Click
as answered by @Excelosaurus, i just offering slightly modified way of TextBox change event trapping by @Mathieu Guindon's answer in the post Implementing a change event to check for changes to textbox values and enabling the "apply" button. The full credit of this technique of encapsulating a WithEvents MSForms control goes to @Mathieu Guindon
Public handlers As VBA.Collection ' added
Private Sub CommandButton1_Click()
RowChar = 70
MultiPage1.Pages.Clear
For i = 0 To TextBox1.Value - 1
MultiPage1.Pages.Add
MultiPage1.Pages(i).Caption = "Variable" & i + 1
'Call LabelPerPage
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "NameBox")
With txtbx
.Top = 20
.Left = 100
End With
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "MinBox")
With txtbx
.Top = 50
.Left = 100
End With
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "LsbBox")
With txtbx
.Top = 20
.Left = 300
End With
Set txtbx = UserForm1.MultiPage1.Pages(i).Controls.Add("Forms.TextBox.1", "Mataas")
With txtbx
.Top = 50
.Left = 300
End With
If i = 0 Then
FormulaString = "= C15"
Else
FormulaString = FormulaString & " " & Chr(RowChar) & "15"
RowChar = RowChar + 3
End If
Next i
TextBox2.Value = FormulaString
CommandButton2.Enabled = False ' added
makeEvents ' added
End Sub
Sub makeEvents() ' added
Set handlers = New VBA.Collection
Dim cnt As MSForms.Control
For i = 0 To UserForm1.MultiPage1.Pages.Count - 1
For Each cnt In UserForm1.MultiPage1.Pages(i).Controls
If TypeOf cnt Is MSForms.TextBox Then
Dim textBoxHandler As DynamicTextBox
Set textBoxHandler = New DynamicTextBox
textBoxHandler.Initialize cnt
handlers.Add textBoxHandler
'Debug.Print cnt.Name & i & "Inited"
End If
Next cnt
Next i
End Sub
然后将一个新的类模块添加到您的项目中,将其命名为DynamicTextBox
Then Add a new class module to your project, call it DynamicTextBox
Option Explicit
Private WithEvents encapsulated As MSForms.TextBox
Public Sub Initialize(ByVal ctrl As MSForms.TextBox)
Set encapsulated = ctrl
End Sub
Private Sub encapsulated_Change()
Dim TextEmpty As Boolean
Dim cnt As Control
Dim i As Integer
For i = 0 To UserForm1.MultiPage1.Pages.Count - 1
For Each cnt In UserForm1.MultiPage1.Pages(i).Controls
If TypeOf cnt Is MSForms.TextBox Then
'Debug.Print cnt.Name & i & "checked"
If cnt.Value = "" Then
TextEmpty = True
Exit For
End If
End If
Next cnt
If TextEmpty = True Then
Exit For
End If
Next i
If TextEmpty Then
UserForm1.CommandButton2.Enabled = False
Else
UserForm1.CommandButton2.Enabled = True
End If
End Sub
