Excel VBA：如何将通用控件对象转换为ComboBox对象？

Question

I need to cast a generic VBA form control object into a ComboBox object so that I can add items to it. The generic object won't allow me to insert items into my existing lists

Dim ctlCurrent As MSForms.Control
For Each ctlCurrent In frmItemInput.Controls
    If TypeName(ctlCurrent) = "ComboBox" Then
         Dim lbCurrentComboBox As MSForms.ComboBox
         lbCurrentComboBox = ctlCurrent 'This is where the error occurs, when I try to convert one into another

         ' Adiciona os itens necessários
         lbCurrentComboBox.AddItem ("R")
         lbCurrentComboBox.AddItem ("D")
    End If
Next ctlCurrent

My problem is: I have tons of ComboBoxes in my form and I need to add the same options for all of them. So I would like to do this progrmatically.

Answer 1

您可以使用SET“强制转换”VBA对象，例如：

SET lbCurrentComboBox = ctlCurrent

Answer 2

如果phil的答案不起作用试试

SET lbCurrentComboBox = ctlCurrent.Object
