Picturebox

[Paul Hadfield]

Hi Guys,

Real simple question here I'm sure. I'm trying to display a JPEG in a
picture box (VB.NET 2003).

pb.Image = Image.FromFile("C:\pic.jpg")

Then, later in the program I need to delete the image file from the disk.

pb.Image = Nothing
IO.File.Delete("C:\pic.jpg")

But I can't as the file is still open/in use. If I try to delete the image
file without displaying it in the picture box first it deletes fine, so I
know it's the picture box that's still got hold of the image file somehow.

What am I missing?


Cheers,
Paul.

Hi,

Dim fs As New System.IO.FileStream("C:\bliss.jpg", IO.FileMode.Open)

Dim bm As New Bitmap(fs)

PictureBox1.Image = DirectCast(bm.Clone, Image)

fs.Close()

bm.Dispose()

System.IO.File.Delete("C:\bliss.jpg")

Thanks,

Just go to google and put in the web address then click search. A seach
page should come up with a tranlate link. It's not perfect but it does the
job.

Sorry, but I currently do not plan an English translation. However, the
tips in the FAQ collection are available in English!
