Screens and Graphics
• Properties: Variables whose values can be read and/or written for your project (e.g., Object Color, FileName,
URL, and so forth)
• Methods: Functions from the .NET Component that can be triggered by your project (e.g., open a dialog,
execute a calculation, and so forth)
• Events: Internal messages that can trigger the execution of expressions in your project (e.g., Mouse_Click,
Download_Completed, and so forth)
The properties, methods and events supported by each .NET Component vary according to the component's
implementation.
Caution: When using .NET Components in your project, make sure that the target system (runtime
station) can support the same components and that they are properly installed and registered. Your
project includes links to the .NET Components; however, the installation of these components on the
target system must be done separately. Furthermore, when .NET Components are used on screens
open in remote Thin Clients, the .NET Components must also be manually installed on the Thin
Client stations. The Microsoft Windows operating system installs a large selection of components
by default, but additional components are offered by third-party providers. Consult your .NET
Component provider for further information about how to install.
Selecting and Placing a .NET Control Object
To select and place a .NET Control object in your project screen:
1. On the Graphics tab, in the Libraries group, click .NET Control.
2. When the .NET Framework Components dialog opens (as in the following figure), it contains a list of
all .NET Components that are registered on your computer.
.NET Framework Components dialog
3. Select a component from the list, and then click OK to place it in your project screen. You can also click the
Browse… button to find an unregistered component on your computer.
Tip: Registered .NET Components are typically stored in the following directory:
C:\WINDOWS\Microsoft.NET\Framework\
However, you can have the application include unregistered components in the .NET Framework
Components dialog by editing the project_name.APP file to add this parameter:
[Execution Environment]
DotNetControlPath=OptionalPath
For example:
