针对combobox，为何打开窗体时，click事件可以触发，而change事件不能触发？

Question

Private Sub cmbKind_Click()
File1.Pattern = cmbKind.Text 放在click事件，filelistbox在窗体打开时能实现筛选，而放change则打开窗体时不能筛选，为何？
End Sub

Private Sub Dir1_Change()
File1.Path = Dir1.Path
End Sub

Private Sub Drive1_Change()
Dir1.Path = Drive1.Drive
End Sub

Private Sub File1_Click()
txtFile = File1.FileName
End Sub

Private Sub Form_Load()
'初始化文件类型列表
With cmbKind
.Text = ""
.AddItem "*.exe"
.AddItem "*.doc"
.AddItem "*.xls"
.AddItem "*.mp3"
.ListIndex = 0
End With

End Sub

Answer 1

ComboBox在选择列表项时,为click事件, 可编辑时的编辑内容,为change事件.
