To add controls to a document, display the Control Toolbox, click the control you want to add, and then click on the document. Drag an adjustment handle of the control until the control's outline is the size and shape you want.
Note Dragging a control (or a number of "grouped" controls) from the form back to the Control Toolbox creates a template of that control, which can be reused. This is a useful feature for implementing a standard "look and feel" for your applications.
