    auto fill in pdf from database

    Hello all,

    we have a pdf that we want to auto fill in some of the fields automatically after users enter in data into a web page with basic textbox controls.

    i dont need to create a pdf, i need to fill in the pdf based off the user input from the webpage.

    any suggestions on where i should start looking to do this? ive seen iTextSharps site, but this seems to be a solution to generate a new pdf then go from there.. we have an existing pdf (which acts as a application) that we need to use, just fill in the fields from our webpage.

    anyone done this before and know a solution i can use?

    thanks in advance

    Hey paulweb,

    I think a third-party tool, such as iTextSharp, would be the best way to go in your situation. Using iTextSharp, you can in fact write to an existing PDF file. For example, have a look at this link and scoll down to "Examining step 4: adding content": http://itextsharp.sourceforge.net/tutorial/ch01.html

    Also, since I'm guessing this file will periodically both be written to and read from, I'd pay extra attention to it's read/write attributes, locking, and things of that nature. All this I'm sure can be controlled with iTextSharp, and can be found in their documentation.

    Oh, and lastly, I would also pay very close attention to the machine's CPU/Memory/resources while doing the write process. You never know how some third-party tool might handle it(that's not to say that tools/software on the market don't mess up of course). As a test, try writing a bunch of lines to the file inside a loop.

    Mike

    ya... this is under step 4 , which is in chapter 1 "Creating a Document" ... seems that this is for writing to a pdf that was created with iTextSharp??

    ill have to read more, but if you know FOR SURE that it can write to an already created pdf please let me know.

    Well, I don't know 100%, but I'm pretty sure it's possible. I guess the only way to find out is to give it a shot.
