I have a binary-only copy of an application written in Delphi 7; as part of its execution, it writes some data into a text file (not in plain text).
Is it possible to extract the data from the file if I know part of the input data and have a copy of this file? (What if it's encrypted?) I have no idea about the structure of the mentioned file.
And no, I don't have source code for the application -- I think that's obvious.
Yes it's possible, you would have to reverse engineer this application first (IDA, HIEW) and/or debug it while it stores the data to the file, contact me if you need more help.

So I have an encrypted text I need to decrypt, where do I start and is there a program that automatically recognizes an algorithm ? Here is a snippet of what I need decrypted:

Encrypted text is designed to resemble random numbers. Cryptographic algorithms are designed specifically to keep you from doing exactly what you are trying to do.

I want to monitor a process in windows to check what actions it performs on a particular file including renaming it, or encrypt it. I want to generate events for these actions.
its easier to monitor the file than the process. Take a look at FileSystemWatcher class. http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx

I am working on directshow filters and looking for the filter that take two input pins with one out put
Main idea is i want to write switch filter that can swith from one input pin to another input pin Please help me i am new in directshow filters
No standard filter of this kind. Write your own or look for third party solution. You request quite specific functionality (most likely you would have to make more assumptions as for its operation), so you would probably have to end up with your own custom filter.

can anyone tell me how can i build console based menu in which i can navigate by direction keys to select options. Code should be in bash or shell script.
Look at pdmenu. It is pretty simple to use.
Or in case you need go deeper there is whiptail tool. It also allow you to build dialog box and so on. But it is a little bit harder to use comparing to pdmenu.
What about the dialog command?

Like the 20Q, is there a published algorithm that allows a program to "learn" from user input?
Programs like junk mail filters learn from what you tell it and uses that information to make more insightful choices in the future when classifying an email as junk.
