紧急VB.NET中DataGridView控件如何使用

紧急！！！VB.NET中DataGridView控件怎么使用
如何用代码实现数据的绑定，我写了一个，可以连接到表，可是却不显示数据！大家帮帮忙吧！
Dim conn As OleDbConnection
Dim dataTable As OleDbDataAdapter
Dim dataSet As DataSet
Dim strSQL As String

Private Sub oprData_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
conn = New OleDbConnection()
conn = getDB_Conn()
'conn.Open()
strSQL = "select * from sys_hairstyle"
dataTable = New OleDbDataAdapter(strSQL, conn)
dataSet = New DataSet
dataTable.Fill(dataSet)
DataGridViewInfo.DataSource = dataSet.Tables(0)
DataGridViewInfo.AutoResizeRows()
conn.Close()

End Sub

高手们能给出使用操作的源代码是最好不过啦，先谢谢啦！

------解决方案--------------------
Dim conn As OleDbConnection 
Dim dataTable As OleDbDataAdapter 
Dim dataSet As DataSet 
Dim strSQL As String 

Private Sub oprData_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
conn = New OleDbConnection() 
conn = getDB_Conn() 
'conn.Open() 
strSQL = "select * from sys_hairstyle" 
dataTable = New OleDbDataAdapter(strSQL, conn) 
dataSet = New DataSet 
dataTable.Fill(dataSet) 
DataGridViewInfo.DataSource = dataSet.Tables(0) 
DataGridViewInfo.AutoResizeRows() 
DataGridViewInfo.DataBind()
conn.Close() 

End Sub 

------解决方案--------------------

Dim dataSet As DataSet

dataSet = New DataSet
dataTable.Fill(dataSet)

有没有可能是这样的命名冲突了.

干吗使用相同的名称呢.换一个别的名字试试.
