View 8 RepliesI'm working on a licensing system for my application. I'd like to put all licensing information (licensee name, expiration date, and enabled features) into an object, encrypt that object with a private key, then represent the encrypted data as a single text string which I can send via email to my customers.
I've managed to get the encrypted data into a byte stream, but I don't know how to convert that byte stream into a text value -- something that contains no control characters or whitespace. Can anyone offer advice on how to do that? I've been researching the Encoding class, but I can't find a text-only encoding.
I have lines of text that contain "degree symbols" (ASCII(248)). I want to replace those symbols with an alphabet character (Z).I am changing the line of text into a charArray,iterating through one character at a time. How do I define the ASCII(248) in code to replace each occurence with a Z? Something like string.Replace(ASCII(248), "Z") would be nice, but that doesn't seem to work too well.

I'm working on a way to authenticate users in my app, and what I've come up with is the following method.To write to a database, the user must have an account in SQL server 2008. However, I still want people to be able to view the application if they don't have access, but only read, they can't sync any changes. This is working well, as I have a string array hard coded containing approved users:
Dim Users() As String = {"BWANG", "EDASALLA", "ERICHARDSON", "HALONZO", "JCHAPMAN", "SKIM", "PMACK"}
The one problem with hardcoding is that if I need to ever add a user later on, I'd have to release an update to the program. (which isn't hard as I already have updating built into the app, and users can still download updates even if they can't sync.)
What I'd like to do, is use an encrypted .dat file that contains the user names, and store that with the application, so that i could always be added to, and only one file would need to be downloaded.
I have code in place to encrpt and decrypt the .dat file (called users.dat) and this code works for single text entries in the file. I need to figure out how to load a list however into the array in place.
Imports System
Imports System.IO
Dim userfile as String = "C:users.dat"
Dim Users() As String = Data.Decrypt(File.ReadAllLines(path))
Basically each line in the file will have an encrypted user name, and i want it to decrypt each line and store it back into that authorized user list.
I would like to know how to read from text file that have a line with string A and ignore lines with string B.

My program creates a array of numbers as entered by a user and then finally adds them up. The form should be able to display the numbers typed in by the user. I know how to put one of these numbers into separate labels and could display each number that way but I wanted to know if there is a simple way to display the string that is created as a list in perhaps a read only text box or similar?

I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.
I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
