Can't move tif file after reading it to picturebox

Hi Folks,

The following code crashes on the last statement with a "The process
cannot access the file because it is being used by another process"
exception (fiFax is a FileInfo object):

Dim picbox As New PictureBox
picbox.Image = Drawing.Image.FromFile(fiFax.FullName)
picbox.Dispose()
fiFax.MoveTo(fiFax.Directory.FullName & "\Old\" &
fiFax.Name) ' Exception!!!

If I put the "fiFax.MoveTo" statement before the "FromFile" it works.
Why does the picturebox keeps the file locked even after it is
disposed? How can I release it?

TIA
 
This appears to be a bug in the Windows API itself. The workaround is to
create a dummy tif image and load it into the picbox before attempting to
move the original image. I have the same problem in one of my older
programs that uses the Kodak Image OCX drivers.

Click to expand...

picbox.Image = new Drawing.Image

or

picbox.Image = Drawing.Image.FromFile("dummy.tif")
 
Hi Mike,

I tried your suggestion but the file was still locked. However, I
solved it using:

picbox.Image.Dispose()

before attempting to move the file.

Thanks
