How to handle multiple click events with same Sub

Question

I'm making a game for my visual basic course. I have multiple picture boxes that when clicked will reveal a hidden image individually. The point of the game is to find the matching pictures (simple enough).

On the easiest level, I have 16 picture boxes. The number of picture boxes increases as the difficulty increases.

For each picture box, I currently have an event handler as follows (default created by visual studio):

Private Sub pictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles pictureBox1.Click

Inside, I plan to use this to change the image in the picture box, as follows:

pictureBox1.Image = (My.Resources.picture_name)

I would like to know if there is a way to have one Sub handle ALL the button clicks, and change the appropriate picture box, instead of having 16 separate handlers. For example:

Private Sub pictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
     Handles pictureBox1.Click, pictureBox2.Click, pictureBox3.Click, ... pictureBox16.Click

And do the following:

' Change appropriate picture box

Here's what it looks like (for now):

To find out which PictureBox was clicked you just have to look at the sender variable. Obviously you have to convert it from the Object type to the PictureBox type:

Dim ClickedBox As PictureBox

ClickedBox = CType(sender, PictureBox)
