Description
The Camera control lets you take pictures using your device's camera and display them in a PictureBox. The contents of that PictureBox can be saved in a database or sent to a server. All the settings needed to take a picture can be set at design time in AppStudio: no additional code needs to be written.
The default icon is a camera icon. You can change this to a different icon or text.
The Cameral control has the same properties as a Button, with one addition, the picturebox property.

When saving to an SQL data base via a PHP script, the data can be corrupted. If you encodeURIComponent the Base64 string it is saved ok. As follows:
