Points To Remember!!

-

 * "using" keyword is used to define header file like # is used in c language 

* ReadKey() is used to break the screen as it was getch() in c. 

* Pink/purple icon defines function. 

* c# is purely object oriented programming language.(here program is written inside a class)

* c++ is partially object oriented programming language.(here program can be created without using class, inside main function) 

* The name of first web form created in asp.net is Default.aspx which is not meant to be changed]  

* When we debug our webform with some text written over the design mode then it will show an error [to include the config file ,we have to say 'yes' here]  

 * In dot net ,Config is supported file which actually runs.
    (like in C .obj is supported file which is run during the time of execution ) 

* ['*' symbol says that your file is not yet saved.]

* Our web form will be run in local server (local host)  

* At the time of execution dot net will be in RUNNING mode  then no window will be activated during running mode(you need  to stop debugging to activate windows). 

* After running it in browser copy the link paste it in another tab  then cancel the previous tab that's how multiple tabs will not be created with every single change we just need to refresh the 
browser everytime.

* Refresh- Select the link and press enter key.  

* If you want to take input from the user in a control we use int.parse() to convert the string type into integer then after performing the operation (like adding to numbers and stored it in any variable)
 
* if we want to display the value in control then we use ToString()
   to convert it into string type ...By Default ,it reads string value 

# In C ,NULL is used to clear the variable. Null is called clear statement 

# C supports 16 colors (graphics.h) 

* dot net supports 256 colors and some more. 
 
# In C , bin folder stores all files. 
 
# In C , all header files will be stored in IO (input output)

Parameter Query

-
If we pass the value with (, ' " ! $) symbols in the control that will not be accepted through normal query. Parameter Query is used to accept the value with special symbols in the control like textbox. Parameter Query use a user defined variable with an @ sign.  In Parameter Query control is written in a different syntax. Column name and variable name can not be the same. Without column_name we can not perform Parameter query. Syntax- Insert- string s= "insert into Table_name (Column_name) values (@variable_name)"; cm = new SqlCommand(s,cn); cm.Parameters.AddWithValue("variable_name", control_name); cm.ExecuteNonQuery(); Update- string q = "update Proc_table set name=@name1 where email = @email1"; cm = new SqlCommand(q, cn); cm.Parameters.AddWithValue("name1", TextBox1.Text); cm.Parameters.AddWithValue("email1", TextBox2.Text); cm.ExecuteNonQuery();

SqlDataAdapter - It is used for Grid View Paging Data Adapter reads data in group of 10 records unlike DataReader which reads the data line by line. DataSet - DataSet Object is created, it accepts the data in bulk. Fill() - Fill() is used. CODE - protected void display() { //Connection Code string s = ConfigurationManager.AppSettings["db"]; cn = new SqlConnection(s); cn.Open(); //DataSet Object DataSet ds = new DataSet(); string s = "select * from Videodb"; //SqlDataAdapter object SqlDataReader adp = new SqlDataAdapter(); adp.Fill(ds); GridView1.DataSoruce = ds; GridView1.DataBind(); } Source code-   <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"              Height="589px" Width="483px" OnPageIndexChanging="click...
