How to Hide Only the Close (X) Button

How to hide only the Close (x) button?

You can't hide it, but you can disable it by overriding the CreateParams property of the form.

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

How to disable (or hide) the close (x) button on a JFrame?

If I understand it correctly, this bug report indicates that this is currently not possible.

Can I disable the 'close' button of a form using C#?

You handle the Closing event (and not the Closed event) of the Form.

And then you use e.CloseReason to decide if you really want to block it (UserClose) or not (TaskManager Close).

Also, there is small example Disabling Close Button on Forms on codeproject.

VB.NET Disable/Hide x button but WITHOUT disabling closing altogether

In the properties for the form, set the ControlBox property to False. Then, in the code, when you want to close the form, just call the form's Close method.

However, doing that will not stop the user from closing the window via standard OS methods (e.g. via the button on the task bar, via ALT+F4). In order to stop that, you would need to cancel the closing of the form in its FormClosing event. For instance:

Public Class Form1
    Private _closeAllowed As Boolean = False

    Private Sub Form1_Click(sender As Object, e As EventArgs) Handles Me.Click
        _closeAllowed = True
        Close()
    End Sub

    Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing
        If Not _closeAllowed Then
            e.Cancel = True
        End If
    End Sub
End Class

However, even that won't stop the application from being terminated. For more thorough solutions, you may want to do some searches on best-practices for developing kiosk applications for Windows.

Hide the close X button in Fancybox

If you take a look at the documentation at http://fancybox.net/api it cites an option of showCloseButton that should do the trick.

From the site:

showCloseButton - Option to show/hide close button

Is it possible to disable the close button while still being able to close from elsewhere?

This is a simple boolean example:

bool ExitApplication = false;

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) 
{
    switch(ExitApplication)
    {
      case false:
      this.Hide();
      e.Cancel = true;
      break;

      case true:
      break;
    }
}

So when you want to close your application just set ExitApplication to true.
