title: how to change Excel column width
body: <p>I'm handling an excel file using visual studio 2013, visual basic, windows Forms.</p>
  
  <ul>
  <li>I add new sheet to excel named sheetReport</li>
  </ul>
  
  <p>How to change the column <code>width</code> of b to be 30?</p>
  
  <p>I don't need to use <code>autofit</code>, cause it make text small to fit in cell with it's default width.</p>
  
  <pre><code>xlApp = CreateObject("Excel.Application")
  xlApp.Visible = False
  xlBook = xlApp.Workbooks.Open(FileName)
  SheetReport = CType(xlBook.Sheets.Add(), Excel.Worksheet)
  SheetReport.Name = "Report"
  SheetReport.Range("B2").Value = "Agent Name"
  ' need resize column b
  </code></pre>
