I want to calculate the number of days in asp.net by AJAX calender extender on text box. But i am not getting the right output which i want. I can't find the error which is coming in output. The code is
string a = TextBox1.Text;
string b = TextBox2.Text;
DateTime t1 = Convert.ToDateTime(a);
DateTime t2 = Convert.ToDateTime(b);
TimeSpan days = t2 - t1;
int zile = Convert.ToInt32(Math.Ceiling(365-(days.TotalDays)));
TextBox3.Text = zile.ToString();
I am not getting the right output.
As I see, you are calculating the days difference in the code behind file. You can calculate it easily like below.
TimeSpan diff = Convert.ToDateTime(TextBox2.Text).Subtract(Convert.ToDateTime(TextBox1.Text));
int noOfDays = diff.Days + 1;

EDIT - SOLVED
I have to make a rotation schedule for coworkers for the next year. Some coworkers have standard days off and I do not want to schedule them on those days.
This is the manual outcome I would like to get.
Example: Consultant A does not work on mondays, so I do not want Consultant A to be added to the schedule on a monday.
I then want consultant B to be added to the schedule as a fill-up. Consultant A would be next in line on a tuesday etc. Next would be consultant C but consultant C does not work on wednesdays. Therefore, we need to take consultant D for wednesday and consultant C on a thursday, and so on. When we are at the last consultant of the F column, it needs to start again at consultant A.
I have tried all kinds of formulas, like if statements and arrayformula. But there is no way that I know of to loop through the F column just with formulas.
I am not sure if this is at all clear what I want to achieve here, I am stuck 😄
I am using additionally an add-on to send the schedule to everyone's agenda, thats also the reason why i'd love to automate this, because it would help me SO much.
I did try myself on some coding, but I am no coder and I am not sure if it would be helpful at all to share my failure 😄 But this is what I've tried so far:
function Loop() {
var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var EndRow = ss.getLastRow();
for (var i = 2; i <= EndRow; i++) {
var Day = ss.getRange(i,2).getValue();
var Consultants = ss.getRange(i,6).getValue();
var Off = ss.getRange(i,7).getValue ();
var Count = ss.getRange(i,8).getValue();
if(Day == Off){
ss.getRange(i, 3).setValue(Consultants)
}else{
ss.getRange(i, 3).setValue(Consultants)
}
}
}
EDIT:
I found a way without using apps scripts, costs me some more work manually and first tried it with a shorter team list.
The highlighted yellow cells are the cells in which the day off was identical to the work-day cell. So they got switched.
I did have to copy paste my input list of consultants but if this is the only manual way, its fine :)
Try this:
Code:
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sh = ss.getSheetByName("Sheet1");
var dayCol = sh.getRange("B2:B343").getValues().flat(); //get day column values and convert it to 1d array
var dayOffCol = sh.getRange("G2:G9").getValues().flat(); //get day off values and convert it to 1d array
var dayOffColCopy; //initialize copy
var consCol = sh.getRange("F2:F9").getValues().flat(); //get consultants values or column F
var consColCopy; //initialize copy
var tempArray = []; //storage of final value for column C
for(var i = 0; i < dayCol.length; i++){ //loop through dayCol values
var ctr = (i % consCol.length); //used modulo as counter. the value will return to 0 if the value of i is divisible to the length of consCol or in example 8
//The if statement below will help up reset the value of
//consColCopy and dayOffColCopy once the values are emptied because of the splice()
if(ctr == 0){
consColCopy = consCol.slice();
dayOffColCopy = dayOffCol.slice();
}
//the loop below will get the first non-matching values of dayCol and dayOffColCopy,
//the first non-matching values will be removed to the copy variables using splice()
//and insert it to tempArray using push()
for(var j = 0; j < dayOffColCopy.length; j++){ //loop through dayOffColCopy values
if(dayCol[i] != dayOffColCopy[j]){
tempArray.push(consColCopy.splice(j, 1));
dayOffColCopy.splice(j, 1);
break; //exit loop
}
}
}
sh.getRange(2, 3, tempArray.length, 1).setValues(tempArray); //set the values of temp array to column C
}

Note: Make sure to use the cell that has data in your range and change the sheet name. I also added comments in my code to explain the process.

I have to fetch hours and minutes from time format I am getting from the system however it is showing me error like int month= moment.Month;
DateTime productDate = DateTime.Now;
string twentyFourHourFormatHour =int.Parse(productDate.ToString("HH")).ToString();
Not picking up productdate when trying to store it in string (line 2)
DateTime has properties to expose all of the data you need. There is no need to do elaborate string manipulation.
DateTime date = DateTime.Now();
int hour = date.Hour;
int minute = date.Minute;
When I load a page with a Time object and echo it out on the page through PHP, I get this:
<?= $user->last_login ?>
// 12/30/14, 5:21 pm
When I load data through ajax, it's returned to me like this:
console.log(response.user.last_login);
// 2014-12-30T17:21:31+0000
I haven't set anything different from the default CakePHP 3 setup, and I need events that are added to the page (returned via ajax) to be in the same time format as events that were pulled on page load (return via PHP).
The default output in string format for Time objects is controlled by the setToStringFormat method http://book.cakephp.org/3.0/en/core-libraries/time.html#setting-the-default-locale-and-format-string
It is a good practice to not hardcode a format there, but to only change the current locale so that the right format is selected for you,
But the format that is used to encode to json is not possible to control it via configuration as it is a standard that dates should be presented in such format when encoded in a JSON API. Instead, what you can do is alter the jsonSerialize method in your User entity:
public function jsonSerialize() {
$toEncode = parent::jsonSerialize();
return ['last_login' => (string)$this->last_login] + $toEncode;
}
What it does is converting to string the last_login property before it is encoded to json. Converting to string will then use the globally configured toString format.
You can convert the format of the date using the javascript Date object
JSFiddle
var date = new Date(response.user.last_login)
//returns a timestamp of 1419960091000
var n = date.getTime();
var day = date.getDate();
var month = date.getMonth();
month = month + 1;
//increment the month by 1 as it starts from 0
var year = date.getFullYear();
year = year.toString().substr(2,2);
//this removes the first 2 characters to give yy, remove the above line for yyyy
var hours = date.getHours();
var minutes = date.getUTCMinutes();
var period='am';
if(hours==0){ //At 00 hours we need to show 12 am
hours=12;
}
else if(hours>12){
hours=hours%12;
//remove the above line for 24 hour format
period='pm';
}
Now you can piece together the date in the required format
var last_login = day + '/' + month + '/' + year + ' ' + hours + ':' + minutes + ' ' + period;
//gives 30/12/14 5:21 pm
Hope this helps!
I am having trouble with the following piece of code. Before I paste it, Let me give a bit of history on what should happen.
I have a model containing 2 fields of interest at the moment, which is the name of the order the customer placed, and the date at which he/she placed it. A pre-calculated date will be used to query the dateplaced field (and should only query the dates , and not the time). The query counts the amount of duplicates that occur in the MondayOrder field, and groups them together. Now , when I exclude the where clause which should query the dates, the query runs great. However, The goal of this query is to count the amount of orders for the following week based on the date the order has been placed.
List<string> returnlist = new List<string>();
DateTime dt = getNextWeekMondaysDate().Date;
switch (day)
{
case DayOfWeek.Monday:
{
var CountOrders =
from x in Data.EntityDB.Orders
group x by x.MondayOrder into m
let count = m.Count()
select new
{
MondayOrderItem = m.Key, Amount = count
};
foreach (var item in CountOrders)
{
returnlist.Add(item.MondayOrderItem + " : " +
item.Amount);
}
}
break;
The getNextWeekMondaysDate() method has an overload which I can use, where if I supply it a date, it will get the following Monday's date from the parameter given. The problem is though, LINQ does not accept queries such as the following:
var CountOrders =
from x in Data.EntityDB.Orders
where getNextWeekMondaysDate(x.DatePlaced.Value).Date == dt
group x by x.MondayOrder into m
let count = m.Count()
select new { MondayOrderItem = m.Key, Amount = count };
This is exactly what I must achieve. Is there any workaround for this situation?
UPDATE
Here is the exception I get when I try the 2nd query.
LINQ to Entities does not recognize the method 'System.DateTime getNextWeekMondaysDate(System.DateTime)' method, and this method cannot be translated into a store expression.
You cannot do this directly, as user-defined method calls cannot be translated to SQL by the EF query provider. The provider recognizes a limited set of .NET methods that can be translated to SQL and also a number of canonical functions as well. Anything that cannot be expressed using these methods only is off-limits unless you write your own query provider (which is only theoretically an option).
As a practical workaround, you can calculate an appropriate range for x.DatePlaced.Value in code before the query and then use specific DateTime values on the where clause.
As an intellectual exercise, note that this method is recognized by the query provider and can be used as part of the expression. So this abomination should work too:
var CountOrders =
from x in Data.EntityDB.Orders
where EntityFunctions.AddDays(
x.DatePlaced.Date.Value,
(9 - DateAndTime.DatePart(DateInterval.WeekDay, x.DatePlaced.Value)) % 7)
.Date == dt
group x by x.MondayOrder into m
let count = m.Count()
select new { MondayOrderItem = m.Key, Amount = count };
Linq to Entities doesn't know how to convert arbitrary C# methods into SQL - it's not possible in general.
So, you have to work with the methods it does understand.
In this case, you could do something like this:
DateTime weekBegin = CalculateWeekBegin( dt );
DateTime weekEnd = CalculateWeekEnd( dt );
var CountOrders =
from x in Data.EntityDB.Orders
where x.DatePlaced.Value >= weekBegin && x.DatePlaced.Value < weekEnd
group x by x.MondayOrder into m
let count = m.Count()
select new { MondayOrderItem = m.Key, Amount = count });
I can't seem to find any good reference on this. I have a lot of data in SQL with dates. So I wanted to make a line chart to show this data over time. If I want to show it over a period of days then I need to group by days.. But the LOGDATE is the full date.. not the DAY..
So I have this below, but LINQ doesn't know what 'DayOfYear' property is...
var q = from x in dc.ApplicationLogs
let dt = x.LogDate
group x by new { dayofyear = dt.Value.DayOfYear } into g
select new
{
iCount = g.Count(),
strDate = g.Key
};
In EF core you can use DateTime.Date to get the date portion of a DateTime value.
In EF6 you can use DbFunctions.TruncateTime:
to return the given date with the time portion cleared
var q = from x in dc.ApplicationLogs
let dt = x.LogDate.Date
// EF6:let dt = DbFunctions.TruncateTime(x.LogDate)
group x by dt into g
select new
{
iCount = g.Count(),
strDate = g.Key
};
You want .Date to get the date part of a DateTime not DayOfyear unless you are deliberately trying to put the same day of the year from each year into the group.
Why are you using:
let dt = x.LogDate
group x by new { dayofyear = dt.Value.DayOfYear } into g
instead of just:
group x by x.LogDate.Value.DayOfYear into g
I'm not sure about this, but it's possible using an anonymous object like that in your group by clause is messing up L2S.
Here you go
let d = new DateTime(n.time.Year, n.time.Month, n.time.Day) group n by d into grp select grp
