Handle the FormShown event and set the Location property:
private void frmMain_Shown(object sender, EventArgs e)
{
Location = new Point(Screen.PrimaryScreen.WorkingArea.Width - Width, 0);
}
[edit]
Sorry - didn't notice the VB...
Private Sub frmMain_Shown(sender As Object, e As EventArgs) Handles frmMain.Shown
Location = New Point(Screen.PrimaryScreen.WorkingArea.Width - Width, 0)
End Sub
