Hi ,
I'm using pdfforms (sample create w9 ) which is great but is there a
way not to open the application on the client side but to save it
directly to sql server database for the user to download at a later stage.
Sorry if you have been asked this question before but can't find or
understand any search results on google. (I'm new to asp.net developing )
You don't find a ready-made answer on the net, nor will you get a
ready-made answer here, because there are just too many ways to achieve
what you want. The best way depends on the type of database you have,
your architecture, your environment, etc...
The best anwer you'll get, will consist of some pointers:
When you say you want to store PDFs in a database, you are actually
talking about storing BLOBs. PDF is a binary file format, so you need a
database that can deal with Binary Large OBjects:
http://en.wikipedia.org/wiki/BLOB
Search your database manual to find out how to create a table with BLOB
fields and how to write code (C#? Java?) to INSERT or SELECT such a BLOB.
iText(Sharp) writes a PDF file to an OutputStream. This can be a
FileOutputStream, ServletOutputStream, ByteArrayOutputStream, etc...
If this code to write a BLOB to a record accepts an OutputStream of some
sort, then you're good to go, but chances are that you'll need a byte array.
In that case, you'll need to write your PDF to a ByteArrayOutputStream,
and as soon as you've closed the document, you can use the toByteArray()
method to get the bytes of the file. These bytes form the BLOB that
needs to be inserted in the database.
