先生ありがと！

サンプルを元にやってみたけど
他アプリから値を変えても値が変わらない。。。
値渡しになってる？
Public Structure ST_SUB
Public s1 As Short
Public s2 As Short
End Structure
<StructLayout(LayoutKind.Sequential)> _
Public Class ST_AREA
<MarshalAs(UnmanagedType.ByValArray, SizeConst:=10)> _
Public stSub1 As ST_SUB()
<MarshalAs(UnmanagedType.ByValArray, SizeConst:=10)> _
Public stSub2 As ST_SUB()
<MarshalAs(UnmanagedType.ByValArray, SizeConst:=10)> _
Public stSub3 As ST_SUB()
End Structure

Public stArea As ST_AREA
Declare Function MemOpen Lib "xx.dll" (<MarshalAs(UnmanagedType.Struct)> ByRef Address As ST_AREA) As Integer

Private Sub BtnOpen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnOpen.Click
Dim iRes As Integer
iRes = MemOpen(stArea)
End Sub
