6. Use the Toolbox to add a control: a textbox In toolbox, scroll down until you get to TextBox, double click. This will create a textbox in the upper left corner of form1, called textbox1 Small white squares around the box indicate that it is highlighted or the selected object. Move the textbox to the middle of form1.
