The properties exposed by the My.Computer.Info object return information about the computer from which the application is deployed, as determined at run time. Typically, this data differs from what was available on the development computer.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Resources. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

This example uses the My.Computer.Info.AvailablePhysicalMemory property to display the amount of available physical memory for the computer on which the code runs.

MsgBox("Computer's available physical memory: " & 
    My.Computer.Info.AvailablePhysicalMemory)
