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.


> type=note
> **C1ApplicationZoom** component does not support PanWindow. The start-up form is a Form which is selected in the Start-up Form dropdown list in the project properties window in a Visual Basic project. In a Visual C# project, the Start-up Form is a Form of a parameter of the Program.cs in the Application.Run method.
