Hi, Pros! I have a class

class MyPicture: PictureBox
...

And I have an element on Form pictureBox1. But the problem is that this
element is connected to:

private System.Windows.Forms.PictureBox pictureBox1;

but I want it to be like this:

private MyPicture pictureBox1. But the problem is that Microsoft warns
that I can't edit in there:
...
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
...
this.pictureBox1 = new System.Windows.Forms.PictureBox();
...
}

... as you can see I have no right to edit it like this:

this.pictureBox1 = new MyPicture();


How to overcome this legally?
