My.Application.IsNetworkDeployed Property

Gets a Boolean that represents whether the application was deployed from a network using ClickOnce.

' Usage
Dim value As Boolean = My.Application.IsNetworkDeployed
' Declaration
Public ReadOnly Property IsNetworkDeployed As Boolean

A Boolean that represents whether the application was deployed from a network. The value is True if the current application was deployed from a network; otherwise the value is False.

The My.Application.IsNetworkDeployed property indicates whether the application was deployed from a network using ClickOnce. For more information on ClickOnce applications, see ClickOnce Deployment.

You should check that this property is True before accessing the My.Application.Deployment Property. Otherwise, if the application is not deployed from a network using ClickOnce, reading the My.Application.Deployment property results in an InvalidDeploymentException exception.

For more information on configuring ClickOnce, see Publishing ClickOnce Applications. For more information on deploying a ClickOnce application, see How to: Publish a ClickOnce Application.

For more information on using the My.Application.IsNetworkDeployed property, see Overview of the Visual Basic Application Model.
