How to use VB.net to simulate the "delete" function of the Keyboard?

Question

I have use the OleDbadoptor function in the Toolbox of the Visual Studio 2008 to build a connection from Datagrid to Ms Access, the database fields can be delete by press the delete button of the keyboard, hence I would like to use a button on the form to simulate the delete function of the keyboard, does anyone can tell me how to do it?
