• But...it only hides at Design time....At run time it shows the close button...
  
  What should I do..pls?
  

• In the windows form add this code
  protected override CreateParams CreateParams
  {
  get
  {
  CreateParams param = base.CreateParams;
  param.ClassStyle = param.ClassStyle | 0x200;
  return param;
  }
  }
  
  

• CreateParams param = base.CreateParams;
  
  param.ClassStyle = param.ClassStyle | 0x200;
  
  return param;
  

• go for full screen mode

• Thanks, great...... it worked.
  

• thanks mloefler. :) For VB .NET users.. you can try the code below. I replaced 0x200 with 512 (equivalent of 0x200 in decimal)
  
  Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
  Get
  Dim param As CreateParams = MyBase.CreateParams
  param.ClassStyle = param.ClassStyle Or 512
  Return param
  End Get
  End Property

  protected override CreateParams CreateParams
  
  {

  {
  
  CreateParams param = base.CreateParams;

  return param;
  
  }
  
  }

• nice, its working good.
  but
  after hide the close button,can i enable the close button at run time ? if its posible then, code?
  

• It's working good and it's very useful. Thank You.
  

• i want hide completely or delete that one how?
  

• This disables but does not hide the close button. Have some very finicky clients who want it HIDDEN ..
  

• Go to properties and select false in control box
  

• I really liked the article, and the very cool blog
  

• Hi, This works. But when I open my form at maximized size close, minimize and maximize buttons are coming. how to solve it?
