Also add this bit of code to your form to allow it to be draggable still   Just add it right before the constructor  the method that calls InitializeComponent      private const int WM NCHITTEST   0x84  private const int HTCLIENT   0x1  private const int HTCAPTION   0x2           Handling the window messages     protected override void WndProc ref Message message        base WndProc ref message        if  message Msg    WM NCHITTEST  amp  amp   int message Result    HTCLIENT          message Result    IntPtr HTCAPTION        That code is from  https   jachman wordpress com 2006 06 08 enhanced-drag-and-move-winforms-without-having-a-titlebar   Now to get rid of the title bar but still have a border combine the code from the other response   this ControlBox   false       this Text   String Empty   with this line   this FormBorderStyle   FormBorderStyle FixedSingle     Put those 3 lines of code into the form s OnLoad event and you should have a nice  floating  form that is draggable with a thin border  use FormBorderStyle None if you want no border
