How to use VBA to read the values of a checkbox from an Excel userform

问题

I have created a userform that contains two checkboxes. I would like to be able to do different things depending on whether each box is checked or unchecked. However, it seems like no matter what I do, it will always tell me the original value of the checkboxes (false and false). Here is the code attached to clicking CommandButton1:

Private Sub CommandButton1_Click()

ReadData

End Sub

And here ReadData:

Sub ReadData()

Dim myForm As UserForm
Set myForm = UserForms.Add("ComplaintEntryForm")

Debug.Print (myForm!CheckBox1.Name)
Debug.Print (myForm!CheckBox1.Value)
Debug.Print (myForm!CheckBox2.Name)
Debug.Print (myForm!CheckBox2.Value)

End Sub

No matter how the boxes are checked, the immediate window always shows this:

VBA.UserForms.Add("ComplaintEntryForm").Show
CheckBox1
False
CheckBox2
False

I have a screenshot of the whole operation but it won't let me upload it because I'm a new user.

回答1:

Try this method to load and show the form (this goes in a normal module):

Sub main()

Dim myForm As ComplaintEntryForm

Set myForm = New ComplaintEntryForm
myForm.Show
Set myForm = Nothing

End Sub

In the UserForm's own module, add the following:

Private Sub CheckBox1_Change()

readData

End Sub

Private Sub CheckBox2_Change()

readData

End Sub

Private Sub UserForm_Initialize()

Me.CheckBox1.Value = True
Me.CheckBox2.Value = False

End Sub

Private Sub readData()

Debug.Print Me.CheckBox1.Name
Debug.Print Me.CheckBox1.Value
Debug.Print Me.CheckBox2.Name
Debug.Print Me.CheckBox2.Value

End Sub

I've initialized the two checkboxes to specific values in the Initialize event. This means we are certain about the state the form will start in
