sorry but i'm not getting this. can you explain me with full code. see my image is coming from another page. like page 1 to page 2 captured by webcam. and display on image control on page 2. now all textboxes and image control are filled. when i press save button all record are being save but this image control's image not geing save in binary format it generate error access denied.
my below code is for image control's image convert into binary format.

this below line is for save image into database.
cmd.Parameters.Add("@V_IMAGE", SqlDbType.Binary).Value = bytes;
below code is for image to binary store in database.
string filePath = Server.MapPath(vImage.ImageUrl);
                    FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.ReadWrite);
                    BinaryReader br = new BinaryReader(fs);
                    Byte[] bytes = br.ReadBytes((Int32)fs.Length);
                    br.Close();
                    fs.Close();

then why are you saving it in folder
if you only need to store in database then simply convert your hex to byte and save in database the time you are displaying in image from webcam
byte[] bytes = ConvertHexToBytes(hexString);
and then save this bytes to database

it is very basic error
you have not specified the file name
change your path to this
and your error will go away
K:\StudentManagment\StudentManagment\myText.txt
