  Pic resize

  Nov 21, 2011 08:30 AM|shtrudel|LINK

  Hi there,

  I have a form which I use for uploading pics using the AsyncFileUpload that works as expected. After the AsyncFileUpload.SaveAs ends I am trying to resize the uploaded pic with the following code -

  Protected Sub FileUploadComplete(ByVal sender As Object, ByVal e As EventArgs)
          Dim filename As String = System.IO.Path.GetFileName(AsyncFileUpload1.FileName)
   
          AsyncFileUpload1.SaveAs(Server.MapPath(UploadFolderPath) + filename)
   
          Dim originalBM As New Bitmap(Server.MapPath(UploadFolderPath) + filename)
          Dim newheight As Integer = 300 * originalBM.Height / originalBM.Width
          Dim newSize As New Size(300, newheight)
          Dim newBM As New Bitmap(originalBM, newSize) ' 
          
          Dim newFileName As String = Server.MapPath(UploadFolderPath) + "new." + filename
          newBM.Save(newFileName, originalBM.RawFormat)
          replaceFiles(Server.MapPath(UploadFolderPath) + filename, newFileName)
      End Sub
      '
      Private Function replaceFiles(org As String, newImg As String) As Boolean
          If File.Exists(org) And File.Exists(newImg) Then
              Dim fi As New FileInfo(org)
              Try
                  fi.Replace(newImg, newImg + ".bak")
                  Return True
              Catch ex As Exception
                  Response.Write(ex.Message)
                  Return False
              End Try
   
          Else
              Return False
          End If
   
   
      End Function

  When the code runs I get the following error -

  The process cannot access the file because it is being used by another process.

  How can I avoid this error ?

  Cheers

  Hi,

  you need to disppose the bitmap object to realese all its reasources aftre saving it.

  newBM.Dispose();

  originalBM.Dispose();
