Easy way of retreiving image from Intrinsic database - and exporting it as file?

Question

Hello!

is there a way of doing this?

client would like to "download" image as the exactly the same properties file had at the time of attaching.

this is surly possible, as data is there, but what should one do in order to make thi happen?

THANKS!

regards,

Miro

Answer 1

Open a new FileStream then write the image to it.  The image is a byte array, so it can be put in FileStream.Write

Silverlight 4 (LS1), I think, only allows you to open a filestream with a dialog box, and the user must enter the filename themselves.
Silverlight 5 (LS2) allows you to specify the filename and directory to save to.

Thanx, i will try this.

just one thought - image can be stored to database from multiple sources, like JPG, PNG... how user can know what extension to use?   or just go ahead with JPG and hope for the best? :)

Answer 3

I think the file dialog box in SL4 allows for specifying a filename extension, just not the filename itself, or the directory.

Answer 4

For you have used the database to save the images , why not give a column to save the extension?
