    Question database encryption

    Are you sure that UTF-8 does not support Arabic? This page seems to suggest that it does. You could also have a look at Unicode, ISO-8859-6 or Windows-1256, which all claim to have support for Arabic.

    Question database encryption

    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...

    Question database encryption

    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...

    Question easy way to protect codes

    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...

    Question database encryption

    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...

    Question easy way to protect codes

    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.

    Question easy way to protect codes

    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...

    Question easy way to protect codes

    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...

    Retrieve Logged In users..

    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...

    Question send a mail via smtp

    When you're posting code please can you use the code tags, it makes it much easier for everyone else to read. Are you sure that the port that you're using is the correct port? You would only be getting an SmtpException if the class is unable to connect to the SMTP server. So either it cannot...
