I have a simple problem:
I have an Access database (images.mdb) that has 2 columns: one is the id of
the picture (an integer) and one (column named picture) is a field of type
OLE Object which contains an image (it can store jpg, bmp, gif, but I don't
know what image is stored inside).
I want to retrieve the picture stored in the database and identified by a
given id and display it in a web page (.aspx).
I write in Visual C#, but it does not matter, VB answers are just as
wellcome.
My problem is that this OLE Object field does not contain just the raw array
of bytes that form the image. So I can not just read the array of bytes and
output it to the browser.
no, it contains some extra information about the type of the file stored
(which would be good to know so I can know what kind of image it is). but I
don't know how to get this information.
I also don't know how to separate this information from the actual image.
Does anyone know how to solve this ?
