Hi Pierre,

In a VB .NET Windows application, Form1 is specified as the startup object by default; however, a form-level Main method is not exposed in the source code. Behind the scenes, the Visual Basic .NET compiler inserts a Main method into the IL code to satisfy .NET’s requirement that all programs must have a Main method. This model was chosen to help simplify VB .NET Windows Forms applications. If you don’t want a form to be the first object instantiated in your VB .NET application or you need to pass parameters, you can create a new module and add a Main method to it. For example:

Module MyFirstVBNetProgram
    Function Main(ByVal CmdArgs() As String) As Integer
        ' Process any parameters
        If CmdArgs.Length > 0 Then
           ' Build a string containing all parameters
           Dim Parms, Parameter As String
	     For Each Parameter In CmdArgs
  	         Parms += Parameter & " "
	     Next
	     ' Display the parameters
	     MessageBox.Show(Parms)
        End If
        Return 0
    End Function
End Module

Then right-click on the Project and go into Properties. Change the Startup Object to the name of the Module (for the sample above: MyFirstVBNetProgram).
