I use this function to encrypt my password to store them in database:
UnicodeEncoding encoding = new UnicodeEncoding();
byte[] hashBytes = encoding.GetBytes( mystringpassword );
SHA1 sha1 = new SHA1CryptoServiceProvider();
byte[] cryptPassword = sha1.ComputeHash ( hashBytes );
return cryptPassword;
now how can I get string format from binary password that I stored in database?

like this:
mystringpassword = BitConverter.ToString( hashBytes );

Sorry,I have problem with that.It gives me password like this:
FA-1D-95-84-5B-D6-8D-61-4C-29-8A-1F-E5-4F-72-31-72-41-26-5B-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

Ok then, a couple of options spring to mind:
1) use a loop to convert each byte to a char and append it to a string, e.g.:
<br />
string mtstringpassword = String.Empty<br />
foreach(byte b in hashBytes)<br />
{ mystringpassword += (char)b; }<br />
2) Use base64 encoding to store the hashed password in a "safe" string format and then decode it when needed, or simply compare it to a hashed & base64 encoded pwd when authenticating, e.g:
<br />
string base64HashedPassword = Convert.ToBase64String(hashBytes);<br />
byte[] hashBytes = Convert.FromBase64String(base64HashedPassword);<br />

Sorry,Do you mean this:
string base64HashedPassword = Convert.ToBase64String(mypasswordin bytes);
byte[] hashBytes = Convert.FromBase64String(base64HashedPassword);
string mystringpassword = String.Empty;
foreach(byte b in hashBytes)
{ mystringpassword += (char)b; }
But it gives me some meaningless characters,even if I write only second paragraph,the results are the same.

Either 1 OR 2 - I gave you two different options, don't mix them together now

That's the idea of Hashing a passhrase - once hashed you can never get your original password back.

Just hash the entered password the same way and compare it against the version in the database.

Sorry could you give ore details or code? Thanks.

Well it depends on what you are after but the most common way of handling passwords in databases is to first use a hash algorithmn to hash the password and store it in a database.
When you need to compare a password with the one in the database (such as when a user is logging in) you do the following:
1. Hash the user entered password using the same algorithmn as above.
2. Get the hashed correct password from the database and compare against the user entered password.
3. If they match then the entered password is correct, otherwise the entered password is incorrect.
A hash is a way of uniquely identifing an object, however you cannot retrieve the object from the hash value. Therefore applying a hash to an object is one-way.
You shouldn't really ever need to display someone's password as clear text.

I have a collection that contains Row objects. One of the classes derived from Row has its own collection of Row objects (called GroupRow).
Now. If i specify the row number of 10, it may not be in the original collection, but could be part of the GroupRow objects collection..or better still, one of the rows in the grouprow objects collection could be a group object and its in there....to an infinite extent.
My problem is, i need to be able to get the row - no matter how many groups i have to go through to get it - only i cant work out how im supposed to do this...any ideas?

This sounds like a heirarchy problem - can you provide an example of how you have setup the RowsCollection class?
|

its a simple collection classes, derived from CollectionBase. David stone said i should use Recursion, only i dont have a clue how i would use it.

Has anyone seen one written in c#, I'm looking for an example to write my own for a very specific problem. ( CNC Machine GCode editor)

THANKS, LOOKS NICE, BUT I WAS REALLY LOOKING FOR SOME EXAMPLE CODE SO i COULD SEE HOW TO HANDLE THE CARET IN DOT NET

So why didnt you ask that? I guess you would use platform invoke and call the unmanaged caret functions.
Furthermore you can use a decompiler to see how the person implemented his "caret".

I call it learning as the persons class as it is, wont be of much use as it is. I meant get the idea from it. Not steal code.

PS: Dont you ever look into the .NET's source? Sometimes MSDN is not suffiecient in telling you what a funtion does.
