RE: Images from Database into W

Question

I've found that a good way to store images was not in the database, but
in files on the server in GIF format and then store the filenames in the
database. That way you avoid the BinaryData mess, the cursor
requirement for blobs, and can store in a compressed form..
You just have the service read in the image from the data file and pass
it back to the requestor, if I remember right.. Also nice because the
same GIF files can be used in normal HTML web pages..

Reply: Images from Database into Web SDK 1.1 page
Hi,
I want to be able to read images in from a database and have Forte
generate a web page with those images.
Does anyone know what the MIME type would be for a Forte ImageData
object? Do I have to store the images into the database in gif format
or is there some other MIME format that Forte uses to store ImageData
objects. Also, can Netscape or Internet Explorer read those images?
Here is the ReturnImage page builder method I created:
=============================================================
Response : HTTPResponse = new();
LUIObject_ID : Integer;
LUIObject_TD : TextData = new();
aLUIObject : LUIObject;
aBinaryData : BinaryData = new();
aStream : MemoryStream = new();
// Retrieve LUIObject_ID from http parameters
LUIObject_TD = pRequest.FindNameValue('LUIObject_ID');
LUIObject_ID = LUIObject_TD.IntegerValue;
// Retrieve aLUIObject for the specified LUIObject_ID from the
database.
// This object contains various ImageData attributes which contain the
// icons to display on the web page.
aLUIObject = SODIInfraSOMgrSO.SelectLUIObject(LUIObject_ID);
aBinaryData.SetAllocatedSize(aLUIObject.ClosedLargeIconSize);
aStream.Open(accessMode = SP_AM_READ_WRITE, isBinary = TRUE);
aStream.WriteSerialized(object=aLUIObject.ClosedLargeIcon);
aStream.Seek(0);
aStream.ReadBinary(target = aBinaryData);
// Not sure what MIME type to specify here for ImageData objects
// read in from a database. Any ideas??????????
Response.AssignBinaryResponse(aBinaryData, 'image/x-bitmap');
return Response;
===============================================================
Thanks,
Brendan Duddridge

Hello Denis Segard,
I also try the same method and I use OLE container to store the images into database in Oracle forms 6i.
But, if i try to retrieve the images in report i got that error.
Anyway i store the images into the database but why i shouldn't retrieve it in reports and i can retrieve the images in forms
Is there any problem in my design.
Is there any other easy way to store the images into database in oracle forms 6i...
Waiting 4 ur reply!!!!!!!!
