problems I have mentioned before .) It is also easy to use this hash key to search for objects: int ssn = Int32.Parse(this.SSN.Text);currentEmp = (Employee)members[ssn];if (currentEmp != null){ LastName.Text = currentEmp.LastName; FirstName.Text = currentEmp.FirstName; Salary.Text = currentEmp.Salary.ToString ();} else LastName.Text = "Not Found"; In C #, you can use array syntax to search for

patterns (principles)Dry–don ' t Repeat yourselfOur first object-oriented design principle is: DRY, from the name you can see that DRY (don ' t repeat yourself) means not to write duplicate code, but to abstract it into reusable blocks of code. If you have two or more blocks of the same code, consider abstracting them into a single method, or you use hard-coded values several times, set them as public constants. The advantages of this object-oriented design principle are ease of maintenance. It

Text; Mycommand.fill (Userdataset); } During execution, the values passed in the @au_id are treated as plain text and do not generate SQL injection problems. But in this case, the original stored procedures that need to be noted are written. It is not possible to prevent injection if it i

System routing table (r) for local and remote hosts (n) in the original IP address format. Show Active Network ConnectionsNetstat supports a set of options for displaying active or inactive sockets:-T,-u,-w, and-X displays active TCP, UDP, RAW, or UNIX socket connections, respectively. If you add the-a flag, a socket is also displayed that waits for a connection (in other words, is listening). This will show you all the servers that are now running on the system.For example, entering Netstat-ta

starting station and destination station name (both string, each one row). "Output Form" The travel information from the starting station to the destination station requires the least number of rides. Transfer Information format is as follows: SSN-N1 (M1)-s1-n2 (m2)-...-ESN Among them: SSN and ESN are the starting station name and the destination station name respectively, N is the subway line number, M is

function that uses a null value. (Translator press, such as CREATE INDEX i_tb_col on tab (NVL (Col,null)); CREATE Index i_tb_col on tab (col,0);) F. Avoiding index based operations Do not perform any operations based on the indexed columns unless you create a corresponding index function. or reset the design column so that predicates on the WHERE clause column do not need to be converted. --> below are all inefficient SQL notation. where salary*5 >: myvalue where substr (

If we create a new index: Lastname,firstname,middleinitial INCLUDE (Ssn,phone)Again, this new index is wider than the previous 3 indexes, but the new index has more uses and it has less total overhead (only one index is maintained, only one index on disk, and only one index in the cache).

If the Administrator only logs on from a fixed terminal, the valid ssn client range should also be limited, Prevents sniffing and man-in-the-middle attacks. At the same time, the command history is classified as zero to hide what you have done as much as possible. The c

In fact, every principle requires a lot of space to be clear, but I will try to be concise.Principle 1:dry (Don ' t repeat yourself)That is, instead of writing repetitive code, use the "abs

Status chart statechart diagram shows the possible state of the object and the transfer caused by the state change.The model example shows how to create an online logon system for a bank. The logon process includes entering a valid password and personal account, and then submitting it to the system for verification. The logon system can be divided into four non-overlapping states: Getti
