ApplicationBase Class

Provides properties, methods, and events related to the current application.

Namespace:  Microsoft.VisualBasic.ApplicationServices
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, Resources = HostProtectionResource.ExternalProcessMgmt)]
public class ApplicationBase

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.

For more detailed information, see the Visual Basic topic My.Application Object.

The properties exposed by the My.Application object return data that is associated only with the current application or DLL. No system-level information can be altered with My.Application.

Some members are available only for Windows Forms or console applications.

This example uses the My.Application.CommandLineArgs property to examine the application's command-line arguments. If an argument is found that starts with /input=, the rest of that argument is displayed.

Private Sub ParseCommandLineArgs()
    Dim inputArgument As String = "/input=" 
    Dim inputName As String = "" 

    For Each s As String In My.Application.CommandLineArgs
        If s.ToLower.StartsWith(inputArgument) Then
            inputName = s.Remove(0, inputArgument.Length)
        End If 
    Next 

    If inputName = "" Then
        MsgBox("No input name")
    Else
        MsgBox("Input name: " & inputName)
    End If 
End Sub
