VB.Net: Dynamically Select Image from My.Resources

Found the solution:

UltraPictureBox1.Image = _
    My.Resources.ResourceManager.GetObject(object_name_as_string)

This works for me at runtime too:

UltraPictureBox1.Image = My.Resources.MyPicture

No strings involved and if I change the name it is automatically updated by refactoring.
