what's the vb.Net counterpart of the following blocks in Csharp?

public class NullableDateTimePicker : System.Windows.Forms.DateTimePicker
  {
    // Default Constructor
    public NullableDateTimePicker() : base()
    {
      base.Format = DateTimePickerFormat.Custom;
      NullValue = " ";
      Format = DateTimePickerFormat.Custom;
      CustomFormat = "dd MMM yyyy";

      this.DataBindings.CollectionChanged += new CollectionChangeEventHandler(DataBindings_CollectionChanged);
    }
}




//NullableDateTimePicker is the class from which DateTimePickerEditingControl class inherits.
//IDataGridViewEditingControl is the interface which DateTimePickerEditingControl class implements.
class DateTimePickerEditingControl : NullableDateTimePicker, IDataGridViewEditingControl
    {
	//Constructor
        public DateTimePickerEditingControl()
        {
            this.Format = DateTimePickerFormat.Custom;
            this.CustomFormat = "dd MMM yyyy";
        }
}

It's difficult to translate snippets like this, particularly when they appear to be incomplete but, for the first one, try this:

Public Class NullableDateTimePicker
    Inherits System.Windows.Forms.DateTimePicker

    Rem there needs to be a field or property for this to compile
    Public ReadOnly NullValue As String
    
    Rem Default Constructor
    Public Sub New()
        MyBase.New()
        MyBase.Format = DateTimePickerFormat.Custom
        NullValue = " "
        Format = DateTimePickerFormat.Custom
        CustomFormat = "dd MMM yyyy"
        AddHandler Me.DataBindings.CollectionChanged, AddressOf DataBindings_CollectionChanged
    End Sub

    Rem need an event handler here
    Private Sub DataBindings_CollectionChanged(ByVal Sender As Object, ByVal e As System.ComponentModel.CollectionChangeEventArgs)
       Rem some code may need to be added in here
    End Sub

End Class

and for the second one:

Rem interface and its members need defining somewhere
Interface IDataGridViewEditingControl
   
End Interface

Rem NullableDateTimePicker is the class from which DateTimePickerEditingControl class inherits.
Rem IDataGridViewEditingControl is the interface which DateTimePickerEditingControl class implements.
Class DateTimePickerEditingControl
    Inherits NullableDateTimePicker
    Implements IDataGridViewEditingControl

    Rem Constructor
    Public Sub DateTimePickerEditingControl()
        Me.Format = DateTimePickerFormat.Custom
        Me.CustomFormat = "dd MMM yyyy"
    End Sub

    Rem need to be implement interface members

End Class


EDIT - changed comments to use old Rem keyword in hope it will format better on this site
