>I am adding a usercontrol to a form at runtime. If the control is on the form, and the form is resized, how do I resize the control? I'm not sure how to check to see of the control is on the form and how to get a reference to it.

You can use anchor something like this

this.textBox = new TextBox();
this.textBox.Location = new Point(100, 100);
this.textBox.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right)));
this.Controls.Add(this.textBox);
