PictureBox Problem

Hi

No, I'm not handling any picturebox events. I think, it does not
happens with all images... If you're creating graphics inside the
picturebox it seems to behave correctly but when I use
picturebox.image = image.Fromfile() the image flashes everytime I
enter or leave the picturebox... I don't know why is this happening!!!

Any idea?

Thanks

I can't tell without seeing your code.

I have seen something similar. It would appear that by using the FromFile
method, the method keeps the underlying filestream open. This can cause
headaches in a multi-user environment. Try using the FromStream method
instead and close the stream explicitly.

Let me know how you get on.
