Use Of Property

Whenever assigning some value to the variable use PROPERTY for that purpose.

For e.g.

String name = TextBox1.Text;

In this case we can use…

Private string mName;

Public string Name

{

get{return mName;}

set{mName=value;}

}

this.Name=TextBox1.Text;

Through this we can ensure proper security. And even we can put some validations in the property.

Interface

Try to always use interface. So that it could be easy to write and understand codes for others… for example. To use code where select statement is used.. try to put that code in block like GetValues();

And the code where insert or update statement or proc is used… try to put that code in block like SetValues();

It would be much easier to look at code then.

Assigning values in SQL Statements

We always use select statement like…

Select * from employees where empname = ‘”TextBox1.Text”’ and password =’”TextBox2.Text”’;

This kind of statement can lead to SQL injection… to avoid such things use parameters

Select * from employees where empname=@empname and password=@password;

And again there in one more flaws in the above statement. Never use * in select statement. Always specify column name.

Select empname, password from employees where empname=@empname and password=@password;

Hey Guys, I think that this will be helpful to u all. Rest as and when I will come to know… then I will post it.
