dev WaitDialogForm窗体有关问题vb.net

dev WaitDialogForm窗体问题vb.net
哪些高手用过dev WaitDialogForm，在窗体加载完之前调用一个WaitDialogForm等待窗体，我用以下代码实现了，一切都正常，但是 就是WaitDialogForm 窗体上的漏斗图标没有动（即静止的），本应该是上下不停翻动的，该如何修改呢？？

Public Class Form1
Dim pFrm As WaitDialogForm
  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  Try
  pFrm = New WaitDialogForm("系统正在加载代理点数据,请稍候...", "提示")  
  Dim UserSqlstr As String = "SELECT * FROM oitw"
  objDataAdpter = New SqlDataAdapter(UserSqlstr, objSqlConnection)
  Dim objtable As New DataTable()
  objDataAdpter.Fill(objtable)
  Me.BindingSource1.DataSource = objtable
  Me.GridControl1.DataSource = BindingSource1
  pFrm.Dispose()
  Catch
  MsgBox("错误号：" & Err.Number & "错误描述：" & Err.Description)
  End Try
  End Sub

End Class

------解决方案--------------------
把你的代码改成如下形式：

Public Class Form1

Dim pFrm As WaitDialogForm


Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim th As New Threading.Thread(AddressOf LoadingData)
th.Start()

End Sub

Private Sub LoadingData()

Try
pFrm = New WaitDialogForm("系统正在加载代理点数据,请稍候...", "提示")
Dim UserSqlstr As String = "SELECT * FROM oitw"
objDataAdpter = New SqlDataAdapter(UserSqlstr, objSqlConnection)
Dim objtable As New DataTable()
objDataAdpter.Fill(objtable)
Me.BindingSource1.DataSource = objtable
Me.GridControl1.DataSource = BindingSource1

Catch
MsgBox("错误号：" & Err.Number & "错误描述：" & Err.Description)
End Try

End Sub

End Class
