AsyncHelper for VB.NET

By Fons Sonnemans, 21-apr-2005

I received a mail today from Rolf Gasber asking me whether I could help him with a VB.NET version of the AsyncHelper which I used in an earlier post. Here it is:

Public Class AsyncHelper

    Private Delegate Sub DynamicInvokeShimProc(ByVal d As [Delegate], _
                                 ByVal args() As Object)

    Private Shared _dynamicInvokeShim As _
                                  New DynamicInvokeShimProc(AddressOf DynamicInvokeShim)

    Private Shared _dynamicInvokeDone As _
                                   New AsyncCallback(AddressOf DynamicInvokeDone)

    Public Shared Sub FireAndForget(ByVal d As [Delegate], _
                                  ByVal ParamArray args() As Object)
        _dynamicInvokeShim.BeginInvoke(d, args, AddressOf _
                                 DynamicInvokeDone, Nothing)
    End Sub

    Private Shared Sub DynamicInvokeShim(ByVal d As [Delegate], _
                                   ByVal args() As Object)
       d.DynamicInvoke(args)
    End Sub

    Private Shared Sub DynamicInvokeDone(ByVal ar As IAsyncResult)
       _dynamicInvokeShim.EndInvoke(ar)
    End Sub

End Class
