Get PictureBox with x height returned size of previously loaded image

I'm using VS 2005.
When user selects a image from the FileListBox, the code is

PictureBox.ImageLocation = sFullPath

PictureBox is set to AutoSize. When the newly loaded image is smaller
than the panel size, I want to center it within the panel by
calculating and move the box to a location other than (0,0). The
problem is that when retrieving the current box size
(PictureBox.Width/Height), it returns the previously auto sized
dimensions (base on the previously loaded image). Seems like I need to
run a "wait" function to wait for the new image to be fully loaded AND
the picbox's done auto sizing to get the correct size. How do I do
that?

I haven't tested this, but what if you do "Application.DoEvents" after
setting the ImageLocation? Then does it return the correct size?

Could you try to retrieve the image file into a System.Drawing.Image, get
its Height and Width, center the PictureBox and then set PictureBox.Image
property rather than ImageLocation?

thanks guys but I figured it out. I put the code in
PictureBox.onLoadComplete event .. that's when the new stuff are
dupdated.
