I have used PrintDocument control to use this method. What I am doing exactly is I am just creating a graphic of the winform to print it. As we will proceed with this project we will look at step by step.In this post I have attached the demo so that you can download it also you can see what is the coding to implement this.

Step 1: Namespaces used

using System.Runtime.InteropServices;
using System.Drawing.Imaging;
using System.Drawing.Printing;

Step 2: Win Form Page codding:

public partial class Form1 : Form
{
    PrintDocument PrintDoc1 = new PrintDocument();
    PrintPreviewDialog PPDlg1 = new PrintPreviewDialog();
    PrintPreviewDialog PrintPreviewDialog1 = new PrintPreviewDialog();
    public Form1()
    {
       InitializeComponent();
       PPDlg1.Document = PrintDoc1;
       PrintDoc1.OriginAtMargins = false;
       PrintDoc1.PrintPage += printDocument1_PrintPage;
    }
    private void btnPrint_Click_1(object sender, EventArgs e)
    {
     try
     {
           PrintDoc1.Print();
     }
     catch
     {
           MessageBox.Show("Please try again...", "Saving slip");
     }
   }
   private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
   {
   try
   {
      Graphics grp = panel1.CreateGraphics();
      Size s = panel1.Size;
      Bitmap bmp = new Bitmap(762, 427, grp);
     panel1.DrawToBitmap(bmp, new Rectangle(0, 0, 762, 427));
     e.Graphics.DrawImage(bmp, 0, 0);
   }
   catch
   {
     MessageBox.Show("Please try again...", "Saving slip");
   }
 }
 }
}

Here I am going to give you the code that how we can do this changes manually according to our requirement with datagridview control.
To understand the problem we have assigned the Id for Datagridview control = “DGStudent”.

1. Hide the Column of DataGridView

 DGStudent.Column[0].Visible = "false";

2. Change the width of columns in DataGridView

 DGStudent.Column[1].Width = "200";
 DGStudent.Column[2].Width = "150";

3. Change the Header Text of Column

 DGStudent.Column[1].HeaderText="Student Name";
 DGStudent.Column[2].HeaderText="Father name";

We have a better solution now. We can add a class file and in this file we can write code to fill the combo box so that if we need to fill combo box on different different forms then we need not to write all code every time. Here I am writing the code of both the class file and code page of winForm.

1. Class File named FillCombo Code:

In this class file we will add all the code of database and the code to fill the combo box. we will do this by creating a method in the class. So whenever we need to use this class we need to first create an object of the same class.

public void fillcombox(ref ComboBox cmb, string str)
        {
            try
            {
              strConnectionString ="Data Source=.\\SQLEXPRESS;Initial Catalog=PO;Integrated Security=True";
              SqlConnection cnn=new SqlConnection();
              SqlCommand cmd=new SqlCommand();
              cnn.ConnectionString=strConnectionString;
              cmd.Connection=cnn;
              cmd.CommandType = CommandType.StoredProcedure;
              cmd.CommandName = str;
              IDataReader da = cmd.ExecuteReader();
              cmb.Items.Clear();
              cmb.Items.Add("--Select--");
              while (da.Read())
              {
                    cmb.Items.Add(da[1].ToString());
              }
            }
            catch (Exception ex)
            {
               throw ex;
            }
        }

WinForm Coding part::

Now its turn to implement the code that we have written in class file. here is the coding that will show you how to execute this:

                FillCombo fcmb = new FillCombo();
                fcmb.fillcombox(ref cmbAuthorName, "AUTHOR_DETAILS_SELECTALL");
                cmbAuthorName.SelectedIndex = 0;

In the above code cmbAuthorname is the name of combobox control and “AUTHOR_DETAILS_SELECTALL”  is the name of stored procedure that we have created in SQL Server

Here are the list of Aggregate functions that can be used in T-SQL.

When we use the Try-Catch blocks in T-SQL we need to remember that the Catch block will be written after the Try block so that the error that generates in Try block can be handled immediately by the Catch block.

Sysnax:

BEGIN TRY
         DELETE from Student_Master
         WHERE id=5001
END TRY
BEGIN CATCH
         SELECT  ERROR_NUMBER() as errornumbers;
END CATCH

Note: the ERROR_NUMBER() is the error functions that is predefined in T-SQL library.

Error Functions:

The error functions are used to capture error information that arrives from the Try-Catch statements. The Try-Catch uses the following error functions to keep the error information:

1. ERROR_NUMBER(): This function returns the error number. So that the error can be detected from the predefined error number in SQL.

2. ERROR_MESSAGE(): This function returns the complete text of the error message including length, object names or times.

3. ERROR_SEVERTY(): This function returns the severty of error. If the severty in between 10 to 20 then Try-Catch can handle the error easily. 

4. ERROR_STATE(): This function the error state numbers.

5. ERROR_LINE(): It returns the line number from the routine where the error generated.

6. ERROR_PROCEDURE(): It returns the name of procedure or trigger where the errors generated.

So these are the error functions that we can use inside the SQL Try_Catch block. Also we can use nested Try-Catch block in T-SQL. Nesting Try-Catch block means we can use the Try-Catch block inside the other Try-Catch blocks.

Creating, Altering, Dropping and executing Sproc or Stored Procedure in MS SQL Server

The procedure is as follows:

Step 1: If the non-key attribute is more dependent on another non-key attribute than the table key then move the dependent attribute, together with a copy of the non-key attribute upon which it is dependent. 

Step 2: Make the non-key attribute, upon which it is dependent, the key in the new table.

Step 3: Leave the non-key attribute, upon which it is dependent, in the original table and mark it a foreign key(*).

So here are the steps to normalize a table. In case if the table is still not normalized then we proceed to the 4NF and 5NF but this situation rarely comes.

How to Normalize a Database table: Step-2 Converting the UNF to 1NF

How to Normalize a Database table: Step-3 Converting the 1NF to 2NF

The procedure to convert 1NF to 2NF is as follows:

Step 1: Take each non key attribute and check whether it is dependent on one part of the key or not.

Step 2: If yes then remove the attribute to the new table with a copy of the part of the key it is dependent upon. 

Step 3: If no then check against other part of the key and repeat step 1 again.

Step 4: Still the key attribute is not dependent on one part of the key the keep the attribute in current table.

Your datasource is now converted into the 2NF.

How to Normalize a Database table: Step-2 Converting the UNF to 1NF

Procedure:
Step 1: Identify the repeating attributes.
Step 2: Remove repeating attributes to a table. Remember while doing this not forget to contain a copy of the key from the UNF table.
Step 3: Assign a key to the new table. And a compound key is created. The value for this key must be unique for each entity occurance.

Note: The key from the unnormalized table always becomes the part of the key of the new table.

Now we will see that what is the proce to complete this first step. Remember we are converting the data source into the UNF. After this we need to convert this UNF into 1NF. The process to convert the data source to UNF is as follows:

Step 1: To convert a data source into UNF, first we need to create column heading and we also ignore any calculated field.

Step 2: Now we enter the sample data into table to make it to UNF.

Step 3: To make the table in UNF we need to identify a key for table. 

Step 4: The most important part of this procdure is to remove the duplicate data from the data source. 

If you have followed the above steps on your data source then now your data source is converted into the UNF. After that you need to proceed for the next step of Normalication.
