The C1ApplicationZoom component allows users to zoom all controls of all Forms in the project. Creating and using a C1ApplicationZoom is very similar to using a regular C1Zoom component.  In C1Zoom, you need to add a C1Zoom component to each Form.  In C1ApplicationZoom, you need to add a C1ApplicationZoom component only to the start-up Form because C1ApplicationZoom automatically attaches C1Zoom components to each Form which is accessible from the  Application.OpenForms static property. If there is a C1Zoom or C1ZoomPanel on a Form, C1ApplicationZoom skips the Form so you can continue use these controls to implement custom zoom settings for the specific Form.
