If next button is pressed, selected index is +1 but if previous button, selected index is -1. How do i access the media players next/previous button controls?

I would like to make data binding using BindingSource whereby whenever either Next Button or Previous Button is click the BindingSource position will change to display the data at that position.
I know that if I want use a loop of the BindingSource I could do somthing like vb code below but I am not sure if of binding it seperately. I usually bind it through the properties but this I cant because is an image column which I want to bind and I have to us memorystream to display it to reduce memory usage, so I asign it to arrPic so that whenever the BindingSource position changes the image column will be asign to arrPic.
Dim MyRow as DataRowView
For Each MyRow In dtView
'only use non-repeating names
CurrentPicture = Trim(CStr((MyRow("FileName"))))
If CurrentPicture <> LastName Then
[Code]...
The BindingSource filter the picturenames and add to a listbox. One name may contain about 4 or more pictures so when you select a name from the listbox the bindingsource populate only the pictures have the selected name and you can navigate forward and backwards.All what I want is how to bind a column to a textbox or picturebox by code. I know if it is a dataset I can declare a datarow and bind anything to the columns.

I have a form in VB.net. When the applications runs it populates the data on a datagrid from the database. Then I have an export to excel button which when clicked creates a spreadsheet and dumps all the data in it. Nice!!!Now, what I want to do is have another button to auto email the work to my Boss. The work should be presented to him in a spreadsheet form, therefore I reckon after the export will be ideal or any ideas will be handy
