 Hello,
  This is from MSDN:
  A number of applications use the Clipboard as a temporary repository for data. For example, word processors use it during cut/copy/paste operations. Accessing the Clipboard and storing data there with a Windows application is made possible through the use of the SetDataObject method, which stores the data on the Clipboard using the IDataObject interface. The SetDataObject method does this so that, when the data is later retrieved from the Clipboard, it can be done so in a variety of formats.
  To set data to clipboard:
  Clipboard.SetDataObject(TextBox1.Text) (VB.NET)
  To paste data:
  'Create a new instance of the DataObject interface.
  Dim data As IDataObject = Clipboard.GetDataObject()
  'If the data is text, then set the text of the
  'TextBox to the text in the Clipboard.
  If (data.GetDataPresent(DataFormats.Text)) Then
    TextBox1.Text = data.GetData(DataFormats.Text).ToString()
  End If
