open excel-file including macros in browser

Hallo,

I want to open an excel file which includes macros and buttons in the browser.

Excel files without macros I loaded in the following way:

1. save file as xml (macros get lost here)

2. fileupload and save data in xml_data

3. open as object in html

                
<object id      = 'myexcel'
        classid = 'CLSID:0002E510-0000-0000-C000-000000000046'>
  <PARAM NAME='DataType' VALUE='XMLDATA'>
  <PARAM NAME='XMLDATA'  VALUE='<%= xml_data %>'>
</object>

It is possible to do it in the following way. But then it is not inline.

<script type='text/javascript'>

        var exApp = new ActiveXObject("Excel.Application");
        exApp.Visible = true;
        exApp.Workbooks.Open("C:/path/file.xls");

</script>

Has anybody an idea how to open an file including macros in the browser (inline)?
