Excuse me, im new in this forum and learning NAV's :D

Here is my problem,

It seems i cant display any picture from a path name eg: C:\test.jpg to a specific field in a page. ive been try using some

InStream and Declare it as BigText, but i didnt found any type of variable to load an InStream data to a field. heres my latest try :


IF NOT ISSERVICETIER THEN
EXIT;
FileToDownload := 'C:\try.bmp';
FileVar.OPEN(FileToDownload);
FileVar.CREATEINSTREAM(IStream);
BStr.READ(IStream);
FileVar.Close;


when im try to use BStr as Sourceexpr its just give a text ](*,) , how can i display the picture from InStream without using XML DOM or inserting to record as BLOB, or its not possible for me to do this? thanks for your reply. [-o<

    You do not need to "insert" it into BLOB. It is enough only to stream it through temporary blob (table TempBLOB is already part of the standard DB). Read the picture into it and display it where you need, without inserting it into the table...
