VB怎么设置Listbox的行间距
'窗体代码
Dim i As Integer
Dim j, k As Integer
Private Sub Command1_Click()
    '返回 listbox高度？
  ' ii = SendMessage((List1.hwnd), LB_GETITEMHEIGHT, 0, &O0)
    '在原高度中增加一个值
    i = i + 5
      ‘’Debug.Print "i", i
    '设置高度
    k = SendMessage((List1.hwnd), LB_SETITEMHEIGHT,0, ByVal i)
    '这中变量代号一定用“i”？原因不明
    k = SendMessage((List1.hwnd), WM_SETREDRAW, True, 0&)
    ‘Debug.Print "k", k
 
End Sub
Private Sub Form_Load()
    For j = 1 To 5
        '在list1加入几行文字
        List1.AddItem "演示" + Format(j)
    Next
End Sub

Public Const LB_SETITEMHEIGHT = &H1A0
