title: Save instead of saveAs using excel activeX
body: <p>I am using <code>javascript</code> and <code>activeX</code> to save and edit data of an excel document. So far everything works. But now i would like to write a new version where I can update a specific cell and keep the other cells as they where.</p>
  
  <p>Here is the code i am using:</p>
  
  <pre><code>function Write() {
      var Excel, Book; // Declare the variables
      Excel = new ActiveXObject("Excel.Application"); // Create the Excel application object.
      Excel.Visible = false; // Make Excel invisible.
      Book = Excel.Workbooks.Add() // Create a new work book.
  
  
      Book.ActiveSheet.Cells(1,1).Value = document.A1.value;
  
      Book.SaveAs("G:/whiteboard.xls");  
      Excel.Quit(); // Close Excel with the Quit method on the Application object.
      alert("Uppgifter sparade");
     }
  </code></pre>
  
  <p>And I want to save, instead of saveAs.</p>
  
  <p>Any ideas?</p>
