Question

vb中同一个窗口的方法间怎样传值?

比如：
Private Sub listview()
a
end sub
private sub treeview()
dim a as string
a="2"
end sub

怎样把第二个方法的a的值传给第一个方法的a

Answer 1

用窗体级全局变量或模块级全局变量就可以了。
dim a as string
prinvate sub form_load()
treeview
listview
end sub

Private Sub listview()
msgbox a
end sub
private sub treeview()
a="2"
end sub

Answer 2

dim a as string '这句移到最开始，成为全局变量
Private Sub listview()
msgbox a
end sub
private sub treeview()
a="2"
end sub
