I am making an antivirus program and i am having a problem with my database. how can i only get the hash in this string:
693248:ff807bd383d377f7f8f91ed4aa7677ae:Trojan.Agent-178374
i only want between the two ":"s in this string. how is this possible? and also how do i get the last part on the right of the last ":"?
In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

still pretty new to programming in general, but I have most of the basics figured out.I stumbled across this problem today, though. I wanted to try making a simple encoder/decoder. However, I am having trouble getting characters from a string.
I have a list(of char) to separate the individual letters in the message (letterList), and textToConvert is the text that the user types in to be encoded. Here's the section of code my problem exists in:
For i = 0 To textToConvert.Length - 1
letterList(i) = textToConvert.Chars(i)
Next i

One problem is what I want to achieve:
I want to have:
$123.00
$15.00
$1,000.00
$123.50
$45.78
My data comes back with 4 places on the end
123.0000
15.0000
45.7800
35.9000
The $ sign I have in my code does work
so I have"
$123.0000
$15.5000
and so on.
I don't believe there will ever be a point where the last two are anything other than zeros.
I'm trying to make a hash calculator (For testing now)
I know that MD5 is a 1 way(Meaning that there is no decryption for it, yet)
now I was wondering if SHA-1 is a two way. Also, is there any other hashing method that are 2way?
reason is that I want to convert a long string (Lets say 550 chars) into something lower (From 550chars to something lower then 550chars)
I can use a Key, but every possibility will give me bigger length then the actual string.
I am testing for a string if it contains at least n chars in consecutive order: I have this regex but it doesn't seems to work (w1){3,}

I am going to write binary files, but for that i will have to define certain characters like this for example.
x00x00x11x22x33x00x00. I would first need to convert stuff like this to a byte array, and then write it to a binary text file.
