Dynamic Picturebox

Hi!

I'm trying to load a picture into a picturebox on my form at runtime. The picture has to change with the click of a button. How do I do this? I'm retrieving data from an Access database, one of the fields contains a reference to a jpg file. How do I load the pciturebox with the new picture every time I change?

Please help!!

PictureBox.Image = System.Drawing.Image.FromFile("picturefile.jpg")

Dim a As Bitmap
a = New Bitmap("thefilepathstring")
PictureBox.Image = a
