try this instead:

vb Code:
  1. Const SWP_NOSIZE As Integer = &H1
  2. Public Declare Function SetWindowPos Lib "user32" (ByVal hwnd As IntPtr, _
  3. ByVal hWndInsertAfter As Integer, ByVal X As Integer, ByVal Y As Integer, ByVal _
  4. cx As Integer, ByVal cy As Integer, ByVal wFlags As Integer) As Integer

vb Code:
  1. Dim xPosition As Integer = 50
  2. Dim yPosition As Integer = 50
  3. SetWindowPos(Me.Handle, -1, xPosition, yPosition, 0, 0, SWP_NOSIZE)
