用Declare调用DLL的枚举变量值，求助

用VB6生成的zbs112.dll，类名称：clsSet

Option Explicit
'对齐方式
Public Enum Align
    alignLeft = 1
    aligncenter = 2
    alignright = 3
End Enum

在VB6里动态调用此zbs112.dll时，能用API取得上述枚举变量aligncenter,下述如何修改？

Private Declare Function SetAlign Lib "%systemroot%\SysWoW64\zbs112.dll" (ByRef xxx As Align) As Long

Private Sub Form_Load()
    '复制zbs112.dll到系统SysWoW64的文件下,同时注册该控件
    Shell "cmd /c Copy .\zbs112.dll %systemroot%\SysWoW64\", vbHide
    Shell "cmd /c RegSvr32 /s %systemroot%\SysWoW64\zbs112.dll", vbHide
    MsgBox SetAlign(aligncenter)    '显示出此枚举值（值为2）
End Sub

Private Sub Form_Unload(Cancel As Integer)
    End
End Sub
