可以使用一个下拉框或文本框+列表框的方式实现。这样做的好处是下拉框的内容不一定是URL,可以是任意内容。下面是一个用下拉框实现的示例: ' *************Declarations Private Declare Function SendMessage Lib "user32" _ Alias "SendMessageA" _ (ByVal hwnd As Long, _ ByVal wMsg As Long, _ ByVal wParam As Long, _ lParam As Any) _ As Long Private Const WM_SETREDRAW As Long = &HB& Private Const CB_FINDSTRING As Long = &H14C& *************Here is the sub that will implement auto search Public Sub SearchCombo(InControl As Object) On Error GoTo trap Dim StrPos As Long Dim lPos As Long Dim SearchStr As String If TypeOf InControl Is ComboBox Then StrPos = InControl.SelStart SearchStr = Left$(InControl.Text, StrPos) lPos = SendMessage(InControl.hwnd, CB_FINDSTRING, 0, ByVal SearchStr) If lPos >= 0 Then InControl.Text = InControl.List(lPos) InControl.ListIndex = lPos End If With InControl .SelStart = StrPos .SelLength = Len(InControl.Text) End With End If Exit Sub trap: MsgBox Err.Description End Sub '**************Implement it like this************ Private Sub cboParent_Change() Call SearchCombo(cboParent) '<--pass the combo box to the sub by name End Sub 此问题由vbfan回答。 |
