Null reference error when adding picturebox dynamically to tabpage

Getting the exception message:

Object Reference not set to an instance of an object.

My code is:

PictureBox myPicBox = new PictureBox();
myPicBox.Visible = true;
myPicBox.Image = Bitmap.FromFile(@"C:\Users\MyUser\Downloads\1341596825343s1jpg.jpg");
myPicBox.Dock = DockStyle.Fill;
this.MyTabPage.Controls.Add(myPicBox);

Where MyTabPage is the fourth page in a tab control. Any suggestions?

EDIT:

Stack Trace is Here

I suppose your MyTabPage control isn't initialized yet. You should not try to use until after it has been initialized.
