关于listbox的问题,急急

[jourmen]

bv里怎样在listbox里,当显示的信息大于listbox显示面积的时候,出现水平滚动条
垂直滚动条他自己就可以出现,水平的呢?

如果没有水平滚动条属性,如何将和水平滚动条绑定?

你用LISTVIEW控件不就可以吗
ListView1.FlatScrollBar = False
ListView1.FullRowSelect = True

给listbox添加水平滚动条??
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 LB_SETHORIZONTALEXTENT = &H194

Private Sub Demo_LBox_GotFocus()
Dim i As Integer
Dim List_MaxL As Integer

' 获得选项内容的最大长度
For i = 0 To Demo_LBox.ListCount - 1
If Len(Demo_LBox.List(i)) > List_MaxL Then
List_MaxL = Len(Demo_LBox.List(i))
End If
Next i

' 判断是否内容显示不完全，如果是则添加水平滚动条
If Me.TextWidth("x") * List_MaxL > Demo_LBox.Width Then
SendMessage Demo_LBox.hwnd, LB_SETHORIZONTALEXTENT, Me.TextWidth("x") * List_MaxL, ByVal 0&
End If
End Sub

Private Sub Form_Load()
Dim i As Integer

' 为ListBox控件添加选项
For i = 0 To 10
Demo_LBox.AddItem ("This is long item " + CStr(i))
Next i

' 设置窗体坐标尺度模式和字体大小
Me.ScaleMode = vbPixels
Me.FontSize = Demo_LBox.FontSize
End Sub
