return TRUE; // return TRUE unless you set the focus to a control
I'll assume that was supposed to be a question.
I'll also assume that it was you that gifted me the 2-vote for my last answer...
No. No need for me.
I've written code from scratch to create pdf documents containing text, line drawings, images and attachments - any/all of which may be deflated or ascii85 encoded.
One you can understand the format enough, you soon realize that a user can fairly easily remove your digital signature and the implied security it carries.
Hint: find a water-marked pdf and work out how to remove the watermark from _all_ pages.
Clearly, there's several parts to the task -
1. Decide whether you wish to create a 'byte range digest' or an 'object digest'
2. Implement a function (in your own app) to create this digest
3. Implement this same function again in a plug-in signature handler
[EDIT: Digital Signature Removal code added]
Here, a 10 line perl script to strip the digital signatures from a PDF
Also... it is very difficult to protect against these attacks from the operating system... you will be better off using a high end router to limit the rate of SYN packets. Keep in mind that 'Saying No' consumes cpu cycles... and that there is technically no defense to a massive DDOS.
The best defense is to unplug the network cable.
[UPDATE] Your problem has nothing to do with SYN Floods or DOS attacks... your source code has some serious problems.
