Actually, you cannot disable it. What you can do is, place an image over the
button to hide it ( and do nothing when the image is clicked)

What about something like this:

private void Form1_Closing(object sender,
System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true;
}
 
Turn off the Control menu and ALL of the window ornaments will disappear.
You will thus also lose the max, min and help buttons.
 
What about something like this:
private void Form1_Closing(object sender,
System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true;
}
Click to expand...
This will not allow form to close form any other source also. Well i can
assign a bool when form is closed from other source but that is fixing and
not the sloution ...
In Vb it is possible to disable the close button .... isnt there anything
like that in C#

You said the same thing I was thinking of when you mentioned the bool.
You also might be able to test the value of the sender and compare it
to something to see where it came from and decide what to do. I cant
think of anything thats just a single click. You would think something
that simple would be in there. Keep us updated.
 
Hello

[DllImport("user32.dll")]
private static extern int GetSystemMenu(int hwnd, int revert);

[DllImport("user32.dll")]
private static extern int GetMenuItemCount(int menu);

[DllImport("user32.dll")]
private static extern int RemoveMenu(int menu, int position, int flags);

protected void DisableCloseButton()
{
int menu = GetSystemMenu(Handle.ToInt32(), 0);
int count = GetMenuItemCount(menu);
RemoveMenu(menu, count - 1, MF_DISABLED | MF_BYPOSITION);
}
