SQL Server: Storing language specific data in SQL Server table field.

While working on multi language support we need to insert different language data in same field or different fields of a SQL server table.

There are two basic rules one need to keep in mind while storing multi lingual or Unicode data:
·         First is column must be of Unicode data type (i.e., nchar, nvarchar, ntext).
·         And second is that the value must be prefixed with N while insertion.

Below is the sample script with output to understand it better.
USE MASTER
GO
-- Drop and Create TestMultiLingualDB
IF db_id('TestMultiLingualDB') IS NOT NULL
      DROP DATABASE TestMultiLingualDB
GO
SET NOCOUNT ON
GO
CREATE DATABASE TestMultiLingualDB
GO
USE TestMultiLingualDB
GO
CREATE TABLE MultiLanguage (Id INT, Var_Field VARCHAR(50), NVar_Field NVARCHAR(50))
GO
-- Insert Hindi Characters
INSERT INTO MultiLanguage VALUES (1, N'यह एक शब्द है', N'यह एक शब्द है')
GO
-- Insert Punjabi Characters
INSERT INTO MultiLanguage VALUES (2, N'ਇਹ ਇੱਕ ਸ਼ਬਦ ਦਾ ਹੁੰਦਾ ਹੈ', N'ਇਹ ਇੱਕ ਸ਼ਬਦ ਦਾ ਹੁੰਦਾ ਹੈ')
GO
--Select and see inserted values.
SELECT * FROM MultiLanguage
GO
-- Drop TestMultiLingualDB
USE MASTER
GO

DROP DATABASE TestMultiLingualDB
GO

In the output you can see that value in Var_Field are saved as ????, even though in script N is prefixed while inserting. This is because field is of VARCHAR type.
Id          Var_Field                           NVar_Field
----------- ----------------------------------- -----------------------------------
1           ?? ?? ???? ??                       यह एक शब्द है
2           ?? ??? ???? ?? ????? ??             ਇਹ ਇੱਕ ਸ਼ਬਦ ਦਾ ਹੁੰਦਾ ਹੈ

Note: If you are using a stored procedure to insert the Unicode data, then make sure that N is used before the string while passing the parameter to stored procedure. Also make sure the parameter declared in stored procedure is of Unicode type.

C#: Merging Excel cells with NPOI HSSFWorkbook

In this post we’ll see how to merge the two or more cell with each other while creating the excel sheet using NPOI.
Mentioned below is code to merge multiple cells, in this example we are merging first cell to fifth cell of first row (you can adjust row or cell range by passing particular parameters in CellRangeAddress).
//Created new Workbook var hwb = new NPOI.HSSF.UserModel.HSSFWorkbook(); //Create worksheet with name. var sheet = hwb.CreateSheet("new sheet"); //Create row and cell. var row = sheet.CreateRow(0); var cell = row.CreateCell(0); ; //Set text inside cell cell.SetCellValue("This is Merged cell"); cell.CellStyle.WrapText = true; //define cell range address // parameters: -> first row to last and first cell to last cell var cra = new NPOI.SS.Util.CellRangeAddress(0, 0, 0, 4); //Add merged region to sheet. sheet.AddMergedRegion(cra);
Hope this solution helps you J

Read and parse a CSV file into an array of rows and columns in C#

The following PopulateCsvIntoArraymethod used to read the CSV file into a two-dimensional array of strings.
I have included explanation of method lines, wherever needed. ///<summary> /// Populate the CSV file into an array, /// We assume that every line has the same number of fields and there may be blank lines. ///</summary> ///<returns></returns> privatestring[,] PopulateCsvIntoArray() { // Get path of CSV file. var path = Server.MapPath("~/Folder_Name/testfile.csv"); // Get the file's text using ReadAllText method. string fileData = System.IO.File.ReadAllText(path);
// Split CSV data into lines.     fileData = fileData.Replace('\n', '\r'); string[] lines = fileData.Split(newchar[] { '\r' }, StringSplitOptions.RemoveEmptyEntries);
// Get rows and columns counts. int totalRows = lines.Length;

Calculate Sum and average of two or more Textbox values using JQuery

We can calculate sum and average of values entered in textboxes with the help of small piece of jQuery code.
First of all let’s create a HTML form where we’ll ask user to enter marks in each subject, under body section add following HTML:
<tableclass="demo-table"> <trclass="label"> <tdcolspan="2">Please enter marks(0-99):</td> </tr> <tr> <td>English</td> <td> <inputtype="text"class="txtMarks"name="txtMarks"
