ListBox控件不增大字体怎么加大行间距？

我需要在触摸屏程序中使用LISTBOX控件，默认间距太小，加大字体又太难看，请问在不加大字体的情况下怎么使行间距增大？

VB不是不区分大小写吗？我把wzzwwz(棒子面窝头) 与 of123() 二位的代码拷贝过去的，提示：找不到DLL入口点 sendMessageA in user32 ?

不会吧，控件不会加？
双击工具箱中的 ListBox 就行了。或者但是工具箱中的 ListBox ，然后用鼠标在窗体上画一个。

设置列表项的高度：

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
Const LB_SETITEMHEIGHT = &H1A0
Const CB_SETITEMHEIGHT = &H153

' Set the height in pixels of each entry in a ListBox or ComboBox control

Sub SetListItemHeight(ctrl As Control, ByVal newHeight As Long)
Dim uMsg As Long
If TypeOf ctrl Is ListBox Then
uMsg = LB_SETITEMHEIGHT
ElseIf TypeOf ctrl Is ComboBox Then
uMsg = CB_SETITEMHEIGHT
Else
Exit Sub
End If
' (only the low-order word of lParam can be used.)
SendMessage ctrl.hwnd, uMsg, 0, Byval CLng(newHeight And &HFFFF&)
' It is necessary to manually refresh the control.
ctrl.Refresh
End Sub
