Downloading image without save dialog and saving to disk.

Question

Hi,
I'm a bit lost. I have been checking google and documentation and can't manage to do this.
I'm using a httpservice, and saving with a file stream the lastResult property. But this seems to be not in binary and when saving it is not correctly done.
Could anybody give any tip?.
P.D. Of course I'm talking about an Air app.
Thanks in advance,
Aron.

Hi kavita,
               In Webdynpro u r using attribute of type Resource ,which is binded to FileUpload UI element. From this attribute, u get file in Input stream format which can be converted into byte array like this
byte fileData[] = null;
      try{
            InputStream fileIs = wdContext.currentFile().getFileData().read(false);
            ByteArrayOutputStream bOut = new ByteArrayOutputStream();
            int length;
            byte[] part = new byte[10 * 1024];
            while ((length = fileIs.read(part)) != -1) {
                  bOut.write(part, 0, length);
            fileIs.close();
            fileData = bOut.toByteArray();
            bOut.close();
      } catch (Exception e) {
            wdComponentAPI.getMessageManager().reportSuccess(e.toString());
In webservice u can take a the byte array as input parameter where the uploaded file will be passed as byte array .
In DB u can store it as BLOB .
in case of any other doubt u can revert back to me.
regards
