the process cannot access the file '' because it is being used by another process...

[GaryTexmo]

Use the .Clone() function on the image.

Bitmap tempbm=new Bitmap("./thumbs/" + filename + "-Thumbnail.jpg"); 
thumbCell.Value=tempbm.Clone();
tempbm.Dispose();

No muss, no fuss

Did you give this a try? It definitely looks way slicker than what I have, so I tried implementing it... the file handle is still left open. There is a reason for this, it's intended behaviour by the Image class. The only way I've found to get around this is to load it into memory still...

Please let me know if this worked for you... if it did, I must be doing something wrong.

I didn't try it because I don't want to mess with files at all. Like I said, the program uses more memory when downloading the images to files than it does when I download it to a memorystream, so I'd rather use a memorystream.

I still need help with the example of tlhintoq's suggestion.

[GaryTexmo]

Oh sorry, I was talking to Platter in that particular message. I'm just wondering if he's doing something I'm not to make that work.

Gary: You're saying your file handle is kept open? The .Clone() method should not transfer the open file handle to the new image. But I will double check. I know I was doing the .Clone() to get rid of open file handles, but maybe I did something else to make it work

[GaryTexmo]

(I noticed that about the quoting thing too.... what happened?)

Yea, I used the code you had and it left the handle open for me. I tried nulling the object as well as disposing it and still the same.

[Plater]

Yea, I see that it keeps it open. My situation was a little different (involved Icon files) and seemed to work for that.

I just created this and it seemed to work?
[code=C#]
private static Bitmap OpenBm(string location)
{
Bitmap a = (Bitmap)Bitmap. FromFile(locati on);
Bitmap b = new Bitmap(a.Width, a.Height, a.PixelFormat);
b.SetResolution (a.HorizontalRe solution, a.VerticalResol ution);
//copy any other PropertyItems you may want?
Graphics gb = Graphics.FromIm age(b);
gb.DrawImage(a, 0, 0);

a.Dispose();
return b;
}
[/code]

[GaryTexmo]

Hmmm ok. At that point I think one is as good as the other; the memory streams are working for me so I'll stick with that. Like I said before, I did some reading on the subject and Microsoft intends for this behaviour (though I feel like there should be an option built in).

Yes yes I know I can type [ quote ] and such, but there used to be a nice reply button

[tlhintoq]

I find it interesting that the quote link still exists in other forums such as the lounge:

http://bytes.com/forums/lounge/877890-do-you-buy-extended-warrenties-new-tech

That indicates that it still exists but has been SET to not be on in the various development forums such as this one. That is truly odd.

[GaryTexmo]

I noticed a bit of a change in the appearance of the forums lately and I seem to recall it happened about then. I wonder if a setting got missed in the changeover?

Ah, here's the answer... it was intended.

But I guess they're looking at putting it back in (yay!).

[tlhintoq]

I add my vote/voice to having it back on.
Or maybe on for users>newbie
