After an exhaustive search spanning thousands of nominees from five continents, the International Collective Council of Excellence has announced this year's World's Greatest Business Mind to universal acclaim and fanfare.

The decision was unanimous despite the fact the world-class shortlist comprised such well-known names as Steve Jobs, Warren Buffett, Bruce Wayne, George Soros, and that kid who invented facebook.

Cheers, and don't mind ok...

Today I need to convert between string and hexadecimal in C#...

         public string StrToHex(string plainText)
        {
            char[] charArray = plainText.ToCharArray();
            StringBuilder sb = new StringBuilder();
            int num;
            string hex;
            for (int i = 0; i < charArray.Length; i++)
            {
                if (i > 0)
                {
                    sb.Append("-");
                }
                num = Convert.ToInt32(charArray[i]);
                hex = num.ToString("x");
                sb.Append(hex);
            }
             return sb.ToString();
        }

 ===========

         public string HexToStr(string hexaText)
        {
           string[] strArray = hexaText.Split(new char[] { '-' });
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < strArray.Length; ++i)
            {
                sb.Append((char)Convert.ToInt32(strArray[i], 16));
            }
            return sb.ToString();
        }

 ============ 

Implementation as

string str = "TestString";
string hexStr = StrToHex(str);   // => 54-65-73-74-53-74-72-69-6e-67
str = HexToStr(hexStr); // => TestString

Sample Code Oracle stored procedure - In this simple implementation, call commit at the end of work done, and Rollback if any exception occur.

PROCEDURE SAVE_TWO_THINGS(
IN_THING_ONE IN VARCHAR2,
IN_THING_TWO IN VARCHAR2)
IS

BEGIN

INSERT INTO TABLEONE
(ACTIVE, THING_DESC)
VALUES
('Y', IN_THING_ONE);


INSERT INTO TABLETWO
(ACTIVE, THING_DESC)
VALUES
('N', IN_THING_TWO);

COMMIT;

EXCEPTION WHEN OTHERS THEN 
ROLLBACK;
END;

Today I need to implement transaction in .NET. Front end language was VB.NET and database was Oracle.

This transaction is being implemented using Oracle Data Access Provider - ODP.NET.

Simple implementation is that create and open a connection, begin transaction using that connection, create command using that connection, call stored procedures or statments using command(s), if every thing gone fine and success then call commit of that transaction else rollback, and in last close and dispose connection and transaction.

Be sure not to use commit, rollback or statement that causes transaction invalidate inside the procedure that is being called within .NET transaction, otherwise that .NET transaction scope will no longer valid as within that connection commit or rollback have been called.

Sample code that make my work done is :-

=============

Private Sub Save()
Dim conn As New OracleConnection("ConnString")
Dim trans As OracleTransaction
Dim success as Boolean = False

Try
conn.Open()
 trans = conn.BeginTransaction
success =  saveThingOne(conn)
If success Then
success = saveThingTwo(conn)
End If

If success  Then
 trans.Commit()
else
trans.Rollback()
End If

Catch ex As Exception
 trans.Rollback()
Finally
trans.Dispose()
conn.Close()
conn.Dispose()
End Try
End Sub
