Convert string in textbox to datetime column in sql

Good day.
I'm very newbie in asp.net/c#/linq/etc, and I'm trying to figure it all out.
But it's need to do one small project.
In my view I have a table with datetime/string values and i need to insert this values to mssql database.
On View I have several Html.TextBox'es. By clicking button, TextBox is filled by current datetime.
View header(JS):
<script type="text/javascript">
function setDate(boxID) {
var dateNow = new Date();
var dd = dateNow.getDate();
var mm = dateNow.getMonth() + 1;
var yy = dateNow.getFullYear();
var hh = dateNow.getHours();
var MM = dateNow.getMinutes();
var ss = dateNow.getSeconds();
if (dd < 10) { dd = '0' + dd }
if (mm < 10) { mm = '0' + mm }
if (MM < 10) { MM = '0' + MM }
if (ss < 10) { ss = '0' + ss }
var today = dd + '-' + mm + '-' + yy + ' ' + hh + ':' + MM + ':' + ss;
document.getElementById(boxID).value = today;
}
</script>
View body:
<div class="divTableCell">
#Html.TextBox("p1_t1")
<input type="button" value="OK" onclick='setDate("p1_t1")' />
</div>
<div class="divTableCell">
#Html.TextBox("p1_notice")
</div>
<button id="result "type="submit">Insert data</button>
By clicking the last button i'm trying to insert this values to external database. Table contains columns p1_notice varchar(250) and p1_t1 datetime;
Controller:
public ActionResult EntranceInspection()
{
return View();
}
EntranceInspectionTableDataContext d = new EntranceInspectionTableDataContext();
public ActionResult EntranceInspectionResult()
{
EntranceInspection s = new EntranceInspection();
s.p1_notice = Request["p1_notice"]; // to SQL - ok
s.p1_t1 = Request["p1_t1"]; // error convert string to datetime
d.EntranceInspection.InsertOnSubmit(s);
d.SubmitChanges();
return View("EntranceInspection");
}
Is there any acceptable way to convert value in textbox to datetime and insert to datetime-column? Or I need to do something different at the start?
Thx

You should type cast the text value into the datetime like below.
s.p1_t1 = Convert.ToDateTime(Request["p1_t1"]);
This will help you to insert datetime value in database without error.

You must convert the text value into the datetime thus:
s.p1_t1 = Convert.ToDateTime(Request["p1_t1"]);
This will help you to insert datetime value in database without error. But, maybe can be usefull you garantie that p1_t1 has not a null value if in database the field is not nullabe.
If it is nullabe, you should insert datemin value or other value that is logical for your business.

You can try the following code ,
public ActionResult EntranceInspectionResult()
{
EntranceInspection s = new EntranceInspection();
s.p1_notice = Request["p1_notice"]; // to SQL - ok
s.p1_t1 = Convert.ToDateTime(Request["p1_t1"]);
d.EntranceInspection.InsertOnSubmit(s);
d.SubmitChanges();
return View("EntranceInspection");
}

Unix timestamp adding two days to current day

Hei,
I want to add to a day wrote in a unix format a day or two.
I use DateTime.Now converted to Unix.The idea is if the order is finished before 16:00 the order will be shipped on next working day (datetime.now)+1. If the order is finished after 16:00 the order will be shipped on (datetime.now)+2.
This will be only on working day. If is weekend next working day will be on Monday.
DateTime normalSF;
MyDateTime normal = new MyDateTime();
MyDateTime normal1 = new MyDateTime();
date_ship_form = normal.ConvertToUnix(DateTime.Now);
normalSF = normal1.ConvertToDate(Convert.ToInt64(date_ship_form));
lblDateSF.Text = ((normalSF.Day < 10) ? "0" : "") + normalSF.Day.ToString() + "/" + ((normalSF.Month < 10) ? "0" : "") + normalSF.Month.ToString() + "/" + normalSF.Year.ToString();
This is how I use DateTime Unix in my code.

You can try this
var currdate = DateTime.Now;
long myStartDate = currdate.ToTimeStamp();
var resdate = myStartDate.AddDays(2);
long finaldate = resdate.ToTimeStamp();
You can try to convert the Unix timestamp to DateTime like this:
public static DateTime myDate(double unixTime)
{
System.DateTime dt = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);
return dt.AddSeconds(unixTime).ToLocalTime();
}

Display Current Date and Time

I have to display the current date and time in the Master layout of my views.
I 've added the current date and time
<div class="date-time">#{
#Html.Label(string.Format("{0:F}",System.DateTime.Now))
}
</div>
The problem is need to update the time in real time.
It's not updating until I refresh the page.

Here is my java script code
function updateClock() {
var currentTime = new Date();
var currentHours = currentTime.getHours();
var currentMinutes = currentTime.getMinutes();
var currentSeconds = currentTime.getSeconds();
var currentDay = currentTime.getDay();
var currentMonth = currentTime.getMonth();
// Pad the minutes and seconds with leading zeros, if required
currentMinutes = (currentMinutes < 10 ? "0" : "") + currentMinutes;
currentSeconds = (currentSeconds < 10 ? "0" : "") + currentSeconds;
// Choose either "AM" or "PM" as appropriate
var timeOfDay = (currentHours < 12) ? "AM" : "PM";
// Convert the hours component to 12-hour format if needed
currentHours = (currentHours > 12) ? currentHours - 12 : currentHours;
// Convert an hours component of "0" to "12"
currentHours = (currentHours == 0) ? 12 : currentHours;
// Compose the string for display
var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay;
return currentTimeString;
}
And the Layout file... Need to add the reference of the javascript file and I have added the bundle.
#Scripts.Render("~/bundles/clock")
<script>
function DiplayClock() {
var currentTime = updateClock();
document.getElementById("clock").firstChild.nodeValue = currentTime;
}
</script>
</head>
<body onload="DiplayClock(); setInterval('DiplayClock()', 1000);">
<div class="date-time">
<span id="clock"> </span>
</div>
</body>

A easy way to do it is:
'document.getElementById("date").innerHTML = new Date().toDateString()'

You have to use javascript.
First declare a timer at the beginning of your .js file:
var objTimer;
after that, you have to set the timeout interval in any initial .js function:
objTimer = setTimeout("DisplayDate()", 1000);
and then, of course, code the DisplayDate() function; something like:
function DisplayDate() {
var objDate = new Date;
var intDate = objDate.getDate();
var intDay = objDate.getDay();
var intMonth = objDate.getMonth();
var intYear = objDate.getYear();
var intHours = objDate.getHours();
var intMinutes = objDate.getMinutes();
var intSeconds = objDate.getSeconds()
var strTimeValue = "" + intHours
strTimeValue += ((intMinutes < 10) ? ":0" : ":") + intMinutes
strTimeValue += ((intSeconds < 10) ? ":0" : ":") + intSeconds
var strDate = intMonth + " " + intDate + ", " + intYear + " " + strTimeValue;
document.getElementById('fcr_spanDateTime').innerHTML = strDate;
}
Hope it helps.

Convert Javascript time string to DateTime or TimeSpan in MVC Controller

How do I covert JavaScript string "5:00 PM" to DateTime or TimeSpan when it get send to the MVC controller. I am using
bootstrap-timepicker
// usage
<script type="text/javascript">
$('#timepicker1').timepicker();
</script>
Javascript payload
{
Skip: 0
Status: []
Take: 15
DueTime: "1:00 PM" // keep in mind that this is a string
}
Server Object would be something like
class TimeSheet
{
public TimeSpan DueTime;
}

Use DateTime.Parse. Convert on server(on controller) when your string would transmit with your time.
http://msdn.microsoft.com/ru-ru/library/system.datetime.parse(v=vs.110).aspx

Okay so I read everyhting wrong hence the deleted answer.. !
But I'm not giving up ;)
Your bootstrap-timepicker, will give you a time as this "1:00 PM".
But before that we are going to look on the serverside to see what we can parse into a datetime object.
This is C# for parsing datetime.
string dateString, format;
DateTime result;
CultureInfo provider = CultureInfo.InvariantCulture;
dateString = "15/08/2000 16:58"
format = "dd/MM/yyyy HH:mm"
result = DateTime.ParseExact(dateString, format, provider);
Now as you se your string wont look like that I'm going to assume that you want todays date!
This is function I tend to use most of the times when converting, to 24H clock.
function ConvertTimeformat(str) {
var time = str;
var hours = Number(time.match(/^(\d+)/)[1]);
var minutes = Number(time.match(/:(\d+)/)[1]);
var AMPM = time.match(/\s(.*)$/)[1];
if (AMPM == "PM" && hours < 12) hours = hours + 12;
if (AMPM == "AM" && hours == 12) hours = hours - 12;
var sHours = hours.toString();
var sMinutes = minutes.toString();
if (hours < 10) sHours = "0" + sHours;
if (minutes < 10) sMinutes = "0" + sMinutes;
//Creating the todays date in the right format
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1;//January is 0!`
var yyyy = today.getFullYear();
if(dd<10){dd='0'+dd}
if(mm<10){mm='0'+mm}
var todaysdate = dd+'/'+mm+'/'+yyyy +" " ; //<--I added an extra space!
var hoursNminutes = sHours + ":" + sMinutes
//CREATE THE RIGHT FORMAT FOR DATE.PARSEXACT "dd/MM/yyyy HH:mm"
var dateToParse = todaysdate + hoursNminutes
return dateToParse;
}
To Use the function do like this!
//Call it and provide your bootstrap time. And make it return to a variable
var dateToBeSentToServer = ConvertTimeformat("1:00 PM");
//OR With the bootstraptime as a variable
var dateToBeSentToServer = ConvertTimeformat(timevariable);
Now you can send dateToBeSentToServer to your serverside for parsing!

Convert DateTime To JSON DateTime

I have a WebService which return DateTime Field.
I get a result /Date(1379048144000)/ but
i want just 1379048144000 how can i achieve that.
[WebMethod]
public DateTime GetServerDate()
{
return DateTime.Now;
}
by setting Header Content-Type: application/json; charset=utf-8; i got a result like /Date(1379048144000)/.

You could change your WS to return a long with the value of the DateTime. The value to return is the number of milliseconds since the Unix Epoch (01/01/1970). This could be done with an extension method on DateTime something like:
public static class DateTimeExtensions
{
...
private static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1);
public static long ToUnixTime(this DateTime dateTime)
{
return (dateTime - UnixEpoch).Ticks / TimeSpan.TicksPerMillisecond;
}
...
}
And your web service method might look something like:
public long GetMyDate(...)
{
DateTime dateTime = ...;
return dateTime.ToUnixTime();
}

with Json.NET :
string date = Newtonsoft.Json.JsonConvert.SerializeObject(DateTime.Now);

in client side you can use this function to show a right date to client(I use it on my projects):
function parseJsonDate(jsonDate) {
var offset = new Date().getTimezoneOffset() * 60000;
var parts = /\/Date\((-?\d+)([+-]\d{2})?(\d{2})?.*/.exec(jsonDate);
if (parts[2] == undefined) parts[2] = 0;
if (parts[3] == undefined) parts[3] = 0;
d = new Date(+parts[1] + offset + parts[2] * 3600000 + parts[3] * 60000);
date = d.getDate() + 1;
date = date < 10 ? "0" + date : date;
mon = d.getMonth() + 1;
mon = mon < 10 ? "0" + mon : mon;
year = d.getFullYear();
return (date + "." + mon + "." + year);
};
This function is return right date in format: dd.mm.yyyy, but you can change it if you need. I hope that I help you.

U can always solve your problem when sending a date in a JSON object to JS by converting the date as follows:
var myJSDate = (new Date(parseInt(obj.MyDate.substr(6)))).toJSON();
Where obj.Date contains the date you wanna format.
Then u'll get something like this: "2013-10-25T18:04:17.289Z"
U can always check it in Chrome console by writing:
(new Date()).toJSON();
Hope this helps!

There are two solutions:
client side:
function ToJavaScriptDate(value) {
var pattern = /Date\(([^)]+)\)/;
var results = pattern.exec(value);
var dt = new Date(parseFloat(results[1]));
return (dt.getMonth() + 1) + "/" + dt.getDate() + "/" + dt.getFullYear();
}
It is possible to need alsou to convert into data object
var date = new Date(xxx)
Server side:
Newtonsoft.Json.JsonConvert.SerializeObject(your_object)

Simply write like this to convert your date string in JSON format.
date = "{" + date + "}";

try regex:
var jsonDate = #"/Date(1379048144000)/";
var regex = /-?\d+/;
var jsonDate = re.exec(jsonDate);
var dateOriginal = new Date(parseInt(m[0]));
