How to: Enable a Batch Mode for Window Forms Applications (Visual Basic)
This example uses the My.Application.Startup event to check if the application started with the string /batch as an argument.
To enable a batch mode for a Window Forms Application
Have a project selected in Solution Explorer. On the Project menu, click Properties.
On the Application tab, click View Application Events to open the Code Editor.
Create the method that handles the Startup event. For more information, see How to: Handle Application Events (Visual Basic).
Iterate through the application's command-line arguments, and set the Cancel property of the e object to True if one of the arguments is /batch.
When the Cancel property is set to True, the startup form does not start.
If the Cancel property of the e object is set to True, call the main routine for windowless operation.
Private Sub MyApplication_Startup( ByVal sender As Object, ByVal e As Microsoft.VisualBasic.ApplicationServices.StartupEventArgs ) Handles Me.Startup For Each s As String In My.Application.CommandLineArgs If s.ToLower = "/batch" Then ' Stop the start form from loading. e.Cancel = True End If Next If e.Cancel Then ' Call the main routine for windowless operation. Dim c As New BatchApplication c.Main() End If End Sub Class BatchApplication Sub Main() ' Insert code to run without a graphical user interface. End Sub End Class
