Hadoop将数据附加到hdfs文件并忽略重复的条目(Hadoop append data to hdfs file and ignore duplicate entries)

 只是重复前两个完美的答案。 这里它试图弄清楚至少必须根据用户提供的逻辑设置位置和文本 
 
Private Sub Button1_Click(ByVal sender As System.Object, _
      ByVal e As System.EventArgs) Handles Button1.Click

      ' YOU decide where EACH new label goes and pass the X,Y for each 
      ' new label; YOU decide on the text and pass it.  you can make them
      ' variables, but YOU have to do some of the thinking....

      ' <...> == information YOU provide
      Private x As integer = <where you want the new label>
      Private y as integer = <where you want the new label>
      Private txt as String = <Text for this new label>

      ' EXAMPLEs
      ' a) set text from a textbox
           ' txt = txtLblText.Text
      ' b) Set X position from another code integer variable
           ' x = thisX
      ' c) Set Y position from textbox input
           ' y = Integer.Parse(txtLblYPos.Text)

      Dim lbl as Label = MakeNewLabel(x, y, txt As string)

      Me.Controls.Add(lbl)  

End Sub


Friend function MakeNewLabel(x as integer, y as Integer, txt As String) as label
    Dim lbl As New label

    ' add other label props here as needed

    lbl.Size = New System.Drawing.Size(159, 23)       'set your size
    lbl.Location = New System.Drawing.Point(x, y)  'set your location
    lbl.Text = txt

    Return lbl
End Function

Just a rehash of the previous 2 perfectly good answers. Here it tries to make clear that at least the location and text must be set based on logic provided by the user
