System.drawing.image

Hi,
I have this question.
When I use the FileUpload WebControl to post an Image (= SourceFile) that I
want to resize and write to the server, I keep getting this situation.
If that SourceFile is located in My Documents (as in "C:\Documents and
Settings\29\Mijn documenten\SubFolderFolder\ImgName.jpg"), I keep getting a
'FileNotFoundException'. That doesn't happen when I get the SourceFile from
"C:\Folder\imgName".
What can I do about this ?
Actually I found a workaround, but this gives me an error as well...
I can save the PostedFile like this
PostedFile.SaveAs(imgPath + "DummyName");
After which I can do these steps without any problem
System.Drawing.Image srcImage =
System.Drawing.Image.FromFile(imgPath + DummyName);
Graphics graphicOrig = Graphics.FromImage(srcImage);
graphicOrig.CompositingQuality = CompositingQuality.HighQuality;
graphicOrig.SmoothingMode = SmoothingMode.AntiAlias;
graphicOrig.InterpolationMode =
InterpolationMode.HighQualityBicubic;
Rectangle rectOrig = new Rectangle();
graphicOrig.DrawImage(srcImage, rectOrig);
srcImage.Save(NewFileName, ImageFormat.Jpeg);
srcImage.Dispose();
The final srcImage is perfect, and everything I need but when I want to do
this
File.Delete(imgPath + dummyName);
I get the IOException that File cannot be deleted:
"The process cannot access the file 'ImgPAth\dummyName' because it is being
used by another process."
Does anyone know what I can do about these issues?Try also
graphicOrig.Dispose();

Try getting the actual path of your posted file from System.IO.Path
namespace. You can use it like this:
string FileName =
System.IO.Path.GetFileName(fileUpload.PostedFile.FileName); // fileUpload is
the id of fileupload html control

Sorry forgot to mention. You cannot manipulate an image at client side,
therefore you need to save the image at server in order to resize it. And
for the delete problem, dispose the Graphics and Rectange object that you
have created before deleting the image.
graphicOrig.Dispose();
rectOrig.Dispose();
