Snaplines are new features that give you visual aid and feedback when locating controls on a form or within a container control. When a control is dragged onto a form or container control, snaplines appear, providing cues relating to control alignment.
When a control is dragged near the edge of a form, container control, or other control, a snapline appears, indicating the distance represented by the Margin property. Additionally, snaplines indicating vertical and horizontal alignment of control edges appear when a control that is being dragged comes into alignment with an adjacent control. When a snapline appears, you can drop the control to create an aligned user interface. Horizontal, vertical, and margin snaplines are shown in Figure 2-6.
If snaplines are disabled, you can enable them in the Options dialog box as described in the following steps.
