Adding event to each picturbox I add to my form

I have made an application that allows users to add custom items to a menu overlay using an ini file to save the items on the menu.

I have a class for reading and saving ini files in my project.

To read the items contained in the ini file, I have used a for each loop. Here is my code to do this:

Dim newItem As New PictureBox
newItem.Image = Image.FromFile(item.GetKey("iconLocation").Value)
Me.Controls.Add(newItem)
newItem.SizeMode = PictureBoxSizeMode.StretchImage
newItem.Size = New Point(60, 60)
newItem.Location = New Point(QuickLaunchIcon.Location.X + distanceFromLaunchItem,
                             QuickLaunchIcon.Location.Y)
distanceFromLaunchItem = distanceFromLaunchItem + 72
doneItems.Add(item.Name)

As you can see, I declare a local variable named newItem. However, as the form adds multiple versions of this newItem, I cannot add a handler for each 'newItem' that can run a different sub so if I was to add a handler for newItem, all the instances of newItem would run the same sub on click. However, I would like each newItem to run a different sub on click.

Is there any way I can do this?

EDIT: I have been told how to do this but now I have run into another problem. All the pictureboxes run the same sub but I cannot differentiate which picturebox is being clicked not... Can anyone help me?

Each picture box can be assigned a Name like this:

newItem.Name = "SomeName"

In your event handler you can branch by DirectCast(sender, PictureBox).Name, choose either an If, or a Select Case, the latter is usually less code.

For a lot picture boxes, it's best to use a Dictionary(Of String, PictureBox) and TryGetValue in that. Regular String comparison done in sequence is very slow on big volumes of data.
