网上找了一个listview 打印函数，却不知如何调用,狂汗！
请用过的朋友告诉我如何调用
我是这样调用的
gprintlistview listview， "报表头 "，listview
附函数：
function gprintlistview（byref pobjlistview as listview, pstrheading as string, prn as object) as boolean

' description : print list view
' parameters : listview control, printed page heading
' returns : n/a
