Microsoft.VisualBasic.ApplicationServices
Assembly:
Microsoft.VisualBasic.dll

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

member this.IsNetworkDeployed : bool
Public ReadOnly Property IsNetworkDeployed As Boolean

Property Value

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.

Examples

This example downloads and installs the update after checking that the application is deployed from a network. The Update method does not update the application unless it is out of date. The application has to restart to use the update.

Sub UpdateApplication()
    If My.Application.IsNetworkDeployed Then
        My.Application.Deployment.Update()
    End If
End Sub

Only applications that are ClickOnce-deployed can be updated using the My.Application.Deployment object. For more information on deploying a ClickOnce application, see How to: Publish a ClickOnce Application using the Publish Wizard.

Remarks

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

You should confirm that this property is True before you access the 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 using the Publish Wizard.

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