VBA 使用替代文本填充 Combobox

Question

New to VBA so please forgive what may seem a simple question.

Using MS Word I have produced a simple form. I have a ComboBox that is populated via an array. This works fine. What I am trying to achieve is when an option is selected in this ComboBox, an alternative text entry is actually placed into the document at a Bookmark named Advice .

I am using Bookmarks as placemarkers in the Word document. At the moment the value already defined in the ComboBox is being place in the document, instead of the alternative.

Here is my code.

    Dim myArray1() As String
  'Use Split function to return a zero based one dimensional array
  myArray1 = Split("advice for option one|advice for option two|" _
             & "advice for option three", "|")
  'Use List method to populate listbox
  ComboBox2.List = myArray1 
  Exit Sub
  
  If ComboBox2.List = "advice for option one" Then
        Advice.Text = "This piece of text for option one. It's much longer than that in the DropBox, but it is what is needed."
        
    ElseIf ComboBox2.List = "advice for option two" Then
        Advice.Text = "This piece of text for option two. It's much longer than that in the DropBox, but it is what is needed."
        
    ElseIf ComboBox2.List = "advice for option three" Then
        Advice.Text = "This piece of text for option three. It's much longer than that in the DropBox, but it is what is needed."
        
    Else
        Advice.Text = ""
        
    End If
  
lbl_Exit:
  Exit Sub
End Sub

I'm sure I'm doing something really silly that is stopping this from working.

Thanks!

Sorry, I've just realised that I had missed the key part. Unsurprisingly this still doesn't work.

I've provided the rest of it and included your suggestion.

Private Sub CancelBut_Click()
UserForm.Hide
End Sub

Private Sub EnterBut_Click()
Dim number As Range
Set number = ActiveDocument.Bookmarks("number").Range
number.Text = Me.TextBox1.Value

        Select Case ComboBox2.Value
            Case "advice for option one":
                Advice.Text = "This piece of text for option one."
            Case "advice for option two":
                Advice.Text = "This piece of text for option two."
            Case "advice for option three":
                Advice.Text = "This piece of text for option three."
        End Select
        ActiveDocument.Bookmarks.Add "Advice", Advice
    End If
End Sub

Answer 1

You haven't shown the context in which the code is run. What's the sub, and how is it getting called? And you haven't what type of object the Advice variable is or how it got set. Your code seems to be setting the combo items and trying to act on a combo selection in the same sub. That won't work.

You should create an event procedure within the form to populate the combo when the dialog is initialized.

Private Sub UserForm_Initialize()
Dim myArray1() As String
  'Use Split function to return a zero based one dimensional array
  myArray1 = Split("advice for option one|advice for option two|" _
             & "advice for option three", "|")
  'Use List method to populate listbox
  ComboBox1.List = myArray1
End Sub

The have another event procedure within the form for a combo change event:

Private Sub ComboBox1_Change()
    Dim Advice As Range
    
    If ActiveDocument.Bookmarks.Exists("advice") = True Then
        Set Advice = ActiveDocument.Bookmarks("advice").Range
        
        Select Case ComboBox1.Value
            Case "advice for option one":
                Advice.Text = "This piece of text for option one."
            Case "advice for option two":
                Advice.Text = "This piece of text for option one."
            Case "advice for option three":
                Advice.Text = "This piece of text for option one."
        End Select
    End If
End Sub

This will replace the bookmark placeholder text with the indicated text. Note: the replacement will get rid of the bookmark as well, so it will only work once unless you reset the bookmark. If you want the bookmark to remain, you need to recreate it. The range object hasn't changed, so you can use that to create the new bookmark:

Private Sub ComboBox1_Change()
    Dim Advice As Range
    
    If ActiveDocument.Bookmarks.Exists("advice") = True Then
        Set Advice = ActiveDocument.Bookmarks("advice").Range
        
        Select Case ComboBox1.Value
            Case "advice for option one":
                Advice.Text = "This piece of text for option one."
            Case "advice for option two":
                Advice.Text = "This piece of text for option two."
            Case "advice for option three":
                Advice.Text = "This piece of text for option three."
        End Select
        ActiveDocument.Bookmarks.Add "advice", Advice
    End If
End Sub

So now, after you select an option in the combo box, the text in the doc will be updated, and the bookmark will be reset to the new text. So, you can make a different choice, and the text will be updated again.

Answer 2

You are over writing the text at the bookmark with the following code which is probably run when the form is closed.

Private Sub EnterBut_Click()
    ...
    Set Advice = ActiveDocument.Bookmarks("Advice").Range
    Advice.Text = Me.ComboBox2.Value
    ...
End Sub

Answer 3

Private Sub ComboBox2_Change()
Dim Advice As Range

If ActiveDocument.Bookmarks.Exists("Advice") = True Then
            
    Select Case ComboBox2.Value
        Case "advice for option one":
            ***Advice.Text = "This piece of text for option one."***
        Case "advice for option two":
            Advice.Text = "This piece of text for option two."
        Case "advice for option three":
            Advice.Text = "This piece of text for option three."
    End Select
    
End If

End Sub
