Selectively hide or show certain PDF content over email

I recently received a PDF file from my bank that had many details along with my account number. I wanted to share the PDF with one of my relatives, I immediately forwarded the PDF to him. To my surprise he was not able to see my account number in the PDF, that I was able to see.
Immediately I opened my sent items folder and tried to open the PDF from the sent mail. And to my surprise I was not able to the see the account number there also.
The account number text was visible only when I opened PDF attachment from the original mail. This has gotten me all curious.
Does someone know anything about a mechanism on how to achieve this? How can I do this using itextsharp or a similar library.
Thanks

Save audio files as text tone for Windows Phone Development

I am currently developing an audio app for Windows Phone and I wonder: is it possible to set audio files as a text tone i.e. the sound I get when I receive a text message?
No, you cannot do that via API in your application.
But user can change that setting only if he is running GDR3 or above.

How to print a string from an actual printer on Cocoa Touch

I want to send a string to a printer from an iPad using code.
The trouble is, I want to connect to the printer using wifi, and then send a string to it for printing. But I don't know how to connect to the printer, and how to send the string, hope someone can help me. Thanks.
The printer and the iPad are in the same local area off-line, I want to use the socket to transfer the content that I want to print through the IP address of the printer.
If the printer is configured as an AirPrinter then it's fairly easy using UIPrintInteractionController.
