  I know about that but that disables the entire control box and i need minimize and maximize in there, i just dont want the X close in there.

  Or without the API:
  
  

  Protected Overrides ReadOnly Property CreateParams() As CreateParams Get Dim cp As CreateParams = MyBase.CreateParams Const CS_NOCLOSE As Integer = &H200 cp.ClassStyle = cp.ClassStyle Or CS_NOCLOSE Return cp End Get End Property

  Does anyone have an idea on how to make this work, again i want to disable the x close button and i dont want it to be visible on the form but i do want the minimize on there so the control box is not an option for me. Is this possible

  Ok the code that you posted doesn't work in vb 2005, but indeed if you can give me a working code for the one you posted and maybe an idea on how to go about changing the behaviour

  Thanks that was exactly what i needed Tada it works perfectly.
  
  do you also know the answer to make it completely gone i mean the grayout works perfect but for another application i like to have it gone.

  TaDa,
  
  This works great and does just what I want. I translated it into C#:
  
  

  private const int CS_NOCLOSE = 0x200;
  protected override CreateParams CreateParams
  {
     get
     {
        CreateParams cp = base.CreateParams;
        cp.ClassStyle = cp.ClassStyle | CS_NOCLOSE;
        return cp;
     }
  }

  Hi Andrej,
  
  Closing event of a form as that signature :
  

  Private Sub frmConsigne_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing    ' Code here End Sub

  
  Therefore, "CloseReason" is not a member of System.ComponentModel.CancelEventArgs
  
  How to deal with then
  
  Thanks in advance.
  With regards,
  AlkPonn

  Why don't you simply change the behaviour of your X button Instead of removing it, assign another function to it (minimize window, message box, ...). Why waste a button  
  
  

  private void Form1_FormClosing(object sender, FormClosingEventArgs e) {    if (e.CloseReason == CloseReason.UserClosing)    {       this.WindowState = FormWindowState.Minimized;       e.Cancel = true;    } }

  Option Explicit On Option Strict On Public Class CloseButton   Private Declare Function GetSystemMenu Lib "user32" (ByVal hwnd As Integer, ByVal revert As Integer) As Integer   Private Declare Function EnableMenuItem Lib "user32" (ByVal menu As Integer, ByVal ideEnableItem As Integer, ByVal enable As Integer) As Integer   Private Const SC_CLOSE As Integer = &HF060   Private Const MF_BYCOMMAND As Integer = &H0   Private Const MF_GRAYED As Integer = &H1   Private Const MF_ENABLED As Integer = &H0   Private Sub New()   End Sub   Public Shared Sub Disable(ByVal form As System.Windows.Forms.Form)     ' The return value specifies the previous state of the menu item (it is either     ' MF_ENABLED or MF_GRAYED). 0xFFFFFFFF indicates   that the menu item does not exist.     Select Case EnableMenuItem(GetSystemMenu(form.Handle.ToInt32, 0), SC_CLOSE, MF_BYCOMMAND Or MF_GRAYED)       Case MF_ENABLED       Case MF_GRAYED       Case &HFFFFFFFF         Throw New Exception("The Close menu item does not exist.")       Case Else     End Select   End Sub End Class

  
  
  
  try this in the form load event CloseButton.Disable(me)

  I'm sorry, the code was in C#. The VB equivalent would be:
  
  

  Private Sub Form1_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing     If e.CloseReason = CloseReason.UserClosing Then         WindowState = FormWindowState.Minimized         e.Cancel = True     End If End Sub

  
  
  Basically, what this snippet does, is preventing the form from closing, (e.Cancel = True) and instead it minimizes it (WindowState change). Note that it not only affects the X button but prevents the form from closing at all (I can't say if this is the behaviour you want).
