What doesn't work? Are you not able to use UTF8? Does UTF8 not support Arabic? Be more specific with your response!
I don't remember seeing that question, but ow well. As I mentioned before for the TextBox you would get the encrypted string from the database, then if you have a look at the code...
When you code please use the code tags, it makes your code actually readable. You can do the code tags like
[code ][/code ] (you will need to remove the spaces before the "]")
I've never done anything with other languages, but I would assume that changing the code from using ASCII to UTF8...
If someone decompiles your exe then they will get something similar to the exact code that you used to create the program, I'm not quite certain what you think encrypting something will do, as if you encrypt something within your application then you would need to code to do that, so when the...
You wouldn't decrypt a GridView you would decrypt the data and then load it into the GridView, so by filling a DataTable then decrypting the entries that have been encrypted (which would usually be all entries in a particular column). The same go for the TextBoxes, you would get the data from...
Developer_mahmoud, jmcilhinney has given you a link to a Google search that gives you some very good resources on doing Encryption in VB.NET. You can also have a look on my website SatalKeto.co.uk I have at least one article on there about encryption in VB.NET.

I'm fairly certain that it does work with VB.Net 2005, I use it for work and I use VB.Net 2005.
This wont stop people from cracking it, it will just make it harder, it is NOT possible to stop people from cracking it, if someone wants to crack it then they will.
Someone who reverse engineers code is generally referred to as a cracker not a hacker.
If you just want to obfuscate your code then perhaps you could have a look at Tutorial: Visual Studio 2008 Obfuscating with Dotfuscator.
Where do you propose to store the information about the CPU? As if it...
When you say codes, I assume that you're talking about serials.
The best way that I have heard for ensuring that people aren't able to pirate your software, is to have the business logic on a secure server that you own. So the software would use a web reference to your server, do some validation...
Welcome to the forums :)
I've done something fairly similar to what you seem to be asking, what I did was set up a session table in the database and then add an entry into that table saying that the user that just logged in, logged in at this time. Then periodically have the table cleared of...
Please start your own thread rather than hijacking an old thread.
Also when you do post your own thread please provide more information about what you are trying to achieve and any constraints you have on what you're trying to achieve.
I don't know a huge amount about threading, but I believe you will want to have a read of this article as it will explain what you need to know to get your application to work as you want.

You could do something like this;
Dim enteredString As String = "20100730"
Dim yr As String = enteredString.substring(0,4)
Dim mnt As String = enteredString.substring(4,2)
Dim dy As String = enteredString.substring(6,2)
Dim dte as Date = New Date(yr,mnt,dy)
Hope this helps
