static extern IntPtr BeginUpdateResource(string pFileName,
   [MarshalAs(UnmanagedType.Bool)]bool bDeleteExistingResources);

VB.NET Signature:

    Public Shared Function BeginUpdateResource(ByVal pFileName As String, _
<DllImport("kernel32.dll", SetLastError := False)>
    Public Function BeginUpdateResource(ByVal pFileName As String,
