title: Transfer string from C# app to OPEN Excel 2003 worksheet cell
body: <p>I need to transfer a string from C# app into <strong>already opened</strong> Excel worksheet. I think automation or RDI should be able to do so but dont know how..</p>
  
  <p>As a variation, instead of copying it into a cell - launch a VBA macro / sub with the string as a parameter (if it is easier)...</p>
  
  <p>Please help.</p>
  
  <p>.NET 3.5 / Excel 2003</p>
  
  <p><em>P.S. Not through clipboard - the transfer must be without user intervention.</em> </p>
