Excel VBA：如何将通用控件对象转换为ComboBox对象？

Question

我需要将一个通用的VBA表单控件对象转换为一个ComboBox对象，以便我可以向它添加项目。通用对象不允许我将项目插入现有列表

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

我的问题是：我的表单中有大量的ComboBox，我需要为它们添加相同的选项。所以我想这样做。

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's answer无效，请尝试

SET lbCurrentComboBox = ctlCurrent.Object
