Your code was much simpler. I tried this to call the encryption but it is still storing it in the database as the original text, when I walk through the code I see it get encrypted though:
[MetadataType(typeof(User_Metadata))]
public partial class User
{
partial void OnpasswordChanging(string value)
{
string Password = shared.EncryptDecryptClass.Encrypt(value);
}
}
I do not know how to call the decryption on load either

Yes, it was a simple one I provided you to give you some idea how encryption/decryption can be done.
I told you there are many ways to do that which you can find by Googling.
Anyway, check this out[^].
For DB level you can take look into this as well[^].

Hi all,
I have taken a setup project in C#.
Is there any way to manage the licence of the setup.
For example: a setup can be used only once, when the person try to run it again then it shoud not work.
it has to reflect for all the machine.
can some one know any technique

There might be some better technique but I think you can achieve it through custom action.
Also you might need to ask for the key validate the user installation.
You can find some details in these links -
1. Keygen[^]
2. MSDN Forum[^]
3. SerialNumberTemplate[^]
But I am thinking why you are not using ClickOnce Deployment[^] which Microsoft itself suggesting.

I think what you are asking is:
"Is there a way to make a setup program that will only work one time. When it has been run on any machine, it should not work on any machine, including the original."
If so then:
Try a google at "software licence codes", but anything good is going to cost you money. It depends on how "protective" you are feeling, and how techinical your users are. To be properly protected is going to be a fair amount of work to implement, and will probably require your user to register the installation via the internet or 'phone. Do not forget to protect the exe once installed, or it can be a simple matter to drag and drop it to anoth machine, bypassing your setup program completely.

Okay, I'm obviously missing something simple here.  All I'm trying to do is check a piece of text to ensure that it only contains uppercase letters or numbers.
My snippet looks like this:
<snip>
System.Text.RegularExpressions.Regex rgxTest = new System.Text.RegularExpressions.Regex("[A-Z0-9]*");
MessageBox.Show(rgxTest.IsMatch("abc_!").ToString());
Can someone please explain to me why this is returning True? And how I fix this? 
Thanks!

This is just an idea, but I can explain why I had it:
Taken from the documentation[^]
"Indicates whether the regular expression specified in the Regex constructor finds a match in the input string."
Maybe a zero-length match is still a match? It does fit the pattern, but in a trivial way.
Possible fix: use + instead of * to force non-triviality of the match
|

|

No joy. 
<snip>
System.Text.RegularExpressions.Regex rgxTest = new System.Text.RegularExpressions.Regex("[A-Z0-9]+");
MessageBox.Show(rgxTest.IsMatch("aAa!").ToString());
Still gives me a True.

Again, nope.
I'd already tried that one. The code sets up a pattern of [a-z], and then declares that if your string matches that, then AllCaps = True. How can that be?
So this:
<snip>
System.Text.RegularExpressions.Regex rgxTest = new System.Text.RegularExpressions.Regex("[a-z]");
MessageBox.Show(rgxTest.IsMatch("AAA").ToString());
Which uses the suggested pattern of [a-z] to match all caps, unsurprisingly returns False.
But then this returns True:
<snip>
System.Text.RegularExpressions.Regex rgxTest = new System.Text.RegularExpressions.Regex("[a-z]");
MessageBox.Show(rgxTest.IsMatch("AaA").ToString());
|
|
|
|
|
This time it is because you there actually is a match, namely "A"
edit: if you want the whole string to match you can use the ^ and $ anchors

Thanks Harold, that appears to be the missing link:
<snip>
System.Text.RegularExpressions.Regex rgxTest = new System.Text.RegularExpressions.Regex("^[A-Z]*$");
MessageBox.Show(rgxTest.IsMatch("ABC").ToString()); // True
MessageBox.Show(rgxTest.IsMatch("AbC").ToString()); // False
MessageBox.Show(rgxTest.IsMatch("abc").ToString()); // False
MessageBox.Show(rgxTest.IsMatch("ABC!").ToString()); // False
Which is the behaviour I was after.
Cheers!

Hi,
Try approaching this from another direction. You that want to detect if the input string contains any characters that aren't A-Z0-9.
The expression [^A-Z0-9]+ will match one or more characters not in the set A-Z0-9.
class App {
internal void Run() {
String[] tests = new String[] {"aAa!", "aardvark", "Aardvark", "AARDVARK",
"0123456789", "0123456789a"};
foreach (String s in tests) {
TestRegex(s);
}
}
private static void TestRegex(String test) {
String expr = "[^A-Z0-9]+";
Regex rgxTest = new Regex(expr);
Boolean result = !rgxTest.IsMatch(test);
Console.WriteLine("String {0}\nExpr {1}\nResult {2}\n", test, expr, result);
}
Alan.

Nice as well, thanks Alan.
I'm using this as a regex validation rule in the nettiers[^] framework, so I need to do the "matches" version, rather than the "exceptions" version you've presented ... but I'll definitely hold onto that snippet for future reference!

Hello,
I am building C# desktop application (client) that will connect to SQL Server on remote machine.
There will be many clients connecting to the database at the same time.
What do you advise me to do?
a) Schould every client connect directly to the remote SQL server?
b) Should I create some middle-tier between application and the SQL server, for example some webservice?
If yes, whats the best way to communicate between the middle tier and the client? SOAP?
I'm just new to .NET and I wonder what are drawbacks of either approach. The most important thing for me
is simplicity of the solution , I need to finish thins app as soon as possible.
Thanx
|
|
|
|

For an internal app, I generally just connect to the database from the client.

Take a look at this[^].
and
Image Recognition with Neural Networks[^], this one is from here on CP, although it is not strictly about facial recognition.
This is not an easy subject, so good luck.

Is it realy hard about face recognition ..... some time I tought to work on it for ma final project .... I think it needs some data mining cource???

I think it is, but then I'm not that good at Graphicsy type things.
There is a lot of work going on in the field, but finding easily understood articles on it is not so simple.
I'll probably get a handle on it eventually, I tend to absorb things like that over time, until the little light bulb comes on, then I'm OK.
