The Development Environment Project Explorer The Project Explorer organizes all of the screens, worksheets, and other items that comprise your project and presents them in an expandable tree-view. To open a folder and view its contents, either click the Expand icon to the left of the folder or double-click the folder itself. To close a folder, click the Collapse icon to the left of the folder. If you right-click any item in the Project Explorer, then a shortcut menu will appear with contextual commands for that item. There are four main sections, or tabs, in the Project Explorer: Global, Graphics, Tasks, and Comm.
Global tab The Global tab of the Project Explorer contains the project tags database, as well as other features that apply to the entire project such as the security system, VBScript procedures, and UI translation. Global tab of the Project Explorer The folders on the Global tab are described in the following sections: Project Tags The project tags database contains all of the data tags that you create during project development, such as screen tags (e.g., button1_state ) or tags that read from / write to connected devices. Classes Classes are compound tags that you can create to associate a set of values, rather than a single value, with an object.
For example, where you may normally create separate tags for a tank's pressure, its temperature, and its fill level, you can instead create a "tank" class that includes all three. Shared Database The shared database contains tags that were created in another program and then imported into or integrated with your project. System Tags Page 36
