主题：如何判断某记录窗口 是否打开，如何关闭它

参考代码

For Each dt As DataTable In DataTables
    For Each a As OBJECT In Tables(dt.name).grid.parent.controls
        For Each b As OBJECT In a.controls
            output.show(b.text)
            If b.text = dt.name Then
                msgbox(b.text)
                b.dispose
            End If
        Next
    Next
Next
