Picture Button Controls Overview
Use picture button controls to trigger an action or to select between two different states. They differ from command buttons or toggle buttons in that a picture button can display a bitmap instead of a label.
There are two styles of picture button control: picture command button (CTRL_PICTURE_COMMAND_BUTTON) and picture toggle button (CTRL_PICTURE_TOGGLE_BUTTON).
A sample picture button control appears in the following figure.
