Create New DB by Executing Scripts C#

string sqlConnectionString = @”Integrated Security=True;Initial Catalog=master;Data Source=.”; //Reference Connection String
FileInfo File = new FileInfo(Server.MapPath(“/sample.sql”)); // .SQL path
string script = File.OpenText().ReadToEnd();
SqlConnection conn = new SqlConnection(sqlConnectionString);
Server server = new Server(new ServerConnection(conn));
var db = new Database(server, “sampledb”); // Mention DB Name here i’ve mentioned sampledb as my new DB Name


While generating .sql script in db.Follow these steps

DBname –> Tasks –> Generate Scripts –> select specific database objects (check Tables & SP’s) –> Next –>Advanced(Script Use Database = false) –> OK –>Next

it is mandatory to false Script Use Database if u want to create new DB with different name or else it is not required

Shutdown Your Computer or a Remote PC via Command Prompt

Type shutdown -s  -t 500 -c “I am tired. I don’t want to work anymore.” (with the quotes) in the Command Prompt and press Enter. The -c switch is used in the code to give the reason for shutting down and what is followed in quotes will be displayed in the dialog box as the reason. This can be used to display all sorts of funny messages. One example :-

Skynet has become self aware. John Connor did not stop me. You can not use your PC anymore.

Difference between TextBox and TextBoxFor:

  • @Html.TextBox() is loosely typed method whereas @Html.TextBoxFor() is a strongly typed (generic) extension method.
  • TextBox() requires property name as string parameter where as TextBoxFor() requires lambda expression as a parameter.
  • TextBox doesn’t give you compile time error if you have specified wrong property name. It will throw run time exception.
  • TextBoxFor is generic method so it will give you compile time error if you have specified wrong property name or property name changes. (Provided view is not compile at run time. )

disabling and re-enabling disabled(Single/Multiple) dates in datepicker

Here i’ll be discussing about disabling and re-enabling disabled(Single/Multiple) dates in datepicker:

Make sure to notice * followed by number in this document (eg: *10)

Step 1:(Include js & css files)

//i’ve used multidatespicker plugin for multiple dates selection
<link rel=”stylesheet” href=”; />

Step 2: (Create div & 2 text inputs)

//for a sake we shall remember this text inputs as

<input type=”text” id=”availabledate” /> // textbox1
<input type=”text” id=”removedates” /> // textbox2

// textbox1 is used for saving dates to db
// textbox2 is used for getting selected disabled date in calendar

step 3:(Loading dates in datepicker)

Here i’ll be using Ajax calls for getting dates from db

$(function () {
getdates(); *1 // Calling Function

function getdates() {
type: “POST”,
url: “/Home/GetDates”, *2 // Make sure u have to use small letters
data: ”,
success: function (data) *3 { //Dates Will be returned
var today = new Date(); // Getting present date
altField: ‘#availabledate’, // Assigning selected dates to textbox1
dateFormat: ‘dd/mm/yyyy’, // Assigning date format
beforeShowDay: function (date) {
var dmy = date.getDate() + “/” + (date.getMonth() + 1) + “/” + date.getFullYear(); // converting present date to dd/MM/yyyy format
// By using below condition the dates which are returned from db will get disabled in calendar
// it will be comparing with every date of current month
if ($.inArray(dmy, data) == -1) {
return [true, “”];
} else {
return [false, “myclass”, “Unavailable”]; //if the date is present in list of dates it’ll be changed to unselectable state and myclass will gets appended means we cannot select date
dataType: “json”,
traditional: true,

//Make disabled dates different with other dates by adding color
.ui-datepicker td.myclass > span {
background: green;
font-size: large;
color: black;

// Now we have finished with disabling dates in datepicker

Step 4:(Now,the Game Starts)
// Re-enabling the disabled date in datepicker
// For this Requirement it has taken more development hours than expected
// Here, the disabled dates will get converted to <span>

$(“body”).on(‘click’, “.ui-datepicker td.myclass > span”, function () { //invokes when clicked on disabled date in calendar
var month = getmonthnumber($(‘span.ui-datepicker-month’).text()); *4 //getting current month number
var date = new Date(); // Getting present date
var value = $(this).html() + “/” + month + “/” + $(‘span.ui-datepicker-year’).text(); *5 // converting present date to dd/MM/yyyy format
$(“#remove”).css(‘display’, ‘block’);
$(this).css(‘background’, ‘red’);
appendWords(this); // “this” is used to get selected <td> tag instance

function getmonthnumber(month) {
var collection = [“”, “January”, “February”, “March”, “April”, “May”, “June”, “July”, “August”, “September”, “October”, “November”, “December”];
return collection.indexOf(month);

function appendWords(t) {
var flag = true;
var resultObj = $(“#availabledate”); // Assigning list of selected disabled dates
var outputObj = $(“#removedates”); // Assigning Particular selected disabled date
var testing = resultObj.val().split(“,”); // Splitting list of dates

for (var i = 0; i < testing.length; i++) {
if (testing[i] == outputObj.val()) { // if selected disabled date is selected again this condition will be satisfied in order to eradicate duplicates
flag = false; // flag will be falsed below if condition will not satisfy if flag is false
$(t).css(‘background’, ‘green’); // backgrond color of selected disabled date will be changed
var index = testing[i].indexOf(outputObj.val()); // getting index of selected disabled date
if (index > -1) {
testing.splice(i, 1); // Removes selected disabled date from array
var stringToAppend = testing; // Assigning array to a variable
resultObj.val(stringToAppend + ”); // Assigning variable value to textbox1

if (flag) {
var stringToAppend = resultObj.val().length > 0 ? resultObj.val() + “,” : “”; // Gets Already Selected Dates from textbox1
resultObj.val(stringToAppend + outputObj.val()); // Appending Current Selected date to textbox1

//use textbox1 value to remove dates from db.
//Game Ended Now you can able to remove selected disabled date

// Here i’ve performed operations only for current month
//If you want to perform same operations for multiple months at a time then use minDate,maxDate options inside datepicker
Noted Points(*) marked description:
1) Calling seperate Function is better than writing all stuff in load in order to maintain clean code.
2) In Ajax make sure to use small letters for url if any capital letter is used it may result in failure
3) Make sure u return only dates
4) $(‘span.ui-datepicker-month’).text() will be getting the month which is displayed on datepicker
5) $(‘span.ui-datepicker-year’).text() will be getting the year which is displayed on datepicker

1) If u want to change the colour of selected date not selected disabled date then use
.ui-datepicker td span, .ui-datepicker td a {
padding: 20px 15px !important;
background-color: white;

.ui-widget-content .ui-state-highlight {
border: 2px solid #d3d3d3;
background: #F6F79F;

//That’s All Buddy Have a nice day

disable dates in datepicker

format: ‘d/m/Y’,
formatDate: ‘Y/m/d’,
beforeShowDay: function (date) {
var disableddates = [“20/1/2017”, “12/1/2017”, “16/1/2017”, “25/1/2017”];
var date = date.getDate() + “/” + (date.getMonth() + 1) + “/” + date.getFullYear();
return [disableddates.indexOf(date) == -1];
