Gridview cell data copy to listbox

How can I copy the text of a cell of a selected column of a row of  DataGridView into a listbox?
My Question is how can ,If we use a timer control and alternately select each row first and then copy the cell text of the selected column to the list box?
Means we want to Copy the text from the cells of the selected column of the  row of the datagridview one by one through Timer  to the listbox or textbox. I use the following code for getting one Current Row cell data from DataGridView. Please help

myRegExp.Pattern = "(http|https|ftp|html)\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&%\$#\=~])*/*.html+"

           myMatches = myRegExp.Execute((DataGridView1.CurrentRow.Cells(1).Value.ToString))

           For Each myMatch In myMatches
               ListBox1.Items.Add(myMatch.Value)
           Next
