This sounds like a retarded thing to do. You know that your CString will contain garbage, not the image in any meaningful way ? To do this, you'd need to UUEncode it, thus making it bigger, but making it able to be stored as a string. Then you'd have a representation of a JPEG that it's possible to decode and turn back in to the bytes of a JPEG, inside a CString. But, it would not actually be the information in the original JPEG, let alone useful in any way as an image.

To store it in the MYSQL blob field. Actually i am executing using ExecuteSQl() function which needs a string. I tried reading the file and i got the image bytes in a char array. I just want to copy those into CString. While trying that it just copies the first 4 characters in it. Rest of the characters are omitted. NULL is also there in the char array.
