How to disable Parent form moved in VB.NET

A short preliminary note: there are not parent-child relationships between forms. (I don't mean MDI parent and children, which is not the same thing, also, who needs MDI? :-)) There are owner and owned forms though; I would highly recommend to have all forms owned by the main form which helps application integrity.

Now, about preventing form dragging. Weird enough, this is ridiculously simple to achieve:

1. Add the following code to the the form constructor:
   C#

   public NonMovableForm() {
      InitializeComponent();
      //add this:
      this.ControlBox = false;
      this.Text = null;
   } //NonMovableForm

   
   
   If you want to do the same for a non-main form, I would highly recommend to add ShowInTaskbar = false.
   
2. If you really need it, create a fake control imitating a title bar with Close button on it (or not) and dock it to the top of the form.
3. Do not implement form dragging. :-)
4. Get ready to receive multiple complaints from the users.
5. PROFIT? I'm not sure — see the item above.

Anyway, the problem is solved. Decide for yourself if you really want it.
