Hey Friends,
Developing an Online Shopping System.
Firstly had posted a code regarding MD5 Encryption and it was solved very quickly.
Require the same help again.
While registering an image selected by the User should be inserted into the Database.
Posting a Code which follows the DAO Pattern but i don't know what to insert in the Method to allow it to insert the image into the database.
Thanking You all in advance
public void AddUser(String UserID , String FirstName , String MiddleName , String LastName , String Age , String MobileNumber , String Gender , String City , String EMail , String Username , String Password , String HashWord , String FileName)
throws ClassNotFoundException , SQLException , NoSuchAlgorithmException , FileNotFoundException
{
try
{
MessageDigest md5 = MessageDigest.getInstance("MD5");
md5.update(Password.getBytes());
BigInteger Hash = new BigInteger(1 , md5.digest());
HashWord = Hash.toString(16);
Statement myStatement = ConnectToDatabase();
String SQLQuery = "INSERT INTO Users(FirstName , MiddleName , LastName , Age , MobileNumber , Gender , City , EMail , Username , HashWord , User_Image) VALUES ('" + FirstName + "' , '" + MiddleName + "' , '" + LastName + "' , '" + Age +"' , '" + MobileNumber + "' , '" + Gender +"' , '" + City + "' , '" + EMail + "' , '" + Username + "' , '" + HashWord + "' , '" + FileName + "')";
myStatement.executeUpdate(SQLQuery);
}
catch (ClassNotFoundException CNFE)
{
System.out.println(CNFE);
throw CNFE;
}
catch (SQLException SQLE)
{
System.out.println(SQLE);
throw SQLE;
}
