Add Controls to a Document
To add controls to a document, open 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.
Dragging a control or a number of "grouped" controls from the form back to the Control Toolbox creates a template of the controls, which you can reuse. This is a useful feature for implementing a standard interface for your applications.
