I am getting time span paramter from our client apllication(in Asp.net 3.5 using C#).
When i am Saving this Timepan Parameter at Our Backend (Sql server 2008) Using Linq(In WCF Service) it gives following error:
Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.
My Code is given below:
objsession.s_QuestionMasterTopicInsert(topic.Title, contentId,
Convert.ToDateTime(Time),
topic.IsAvailable, ref strRet,
ref strRetMsg);
// topic.Time(is the time span type )
//I changed Convert.ToDateTime(Time) to
new
DateTime(time.Ticks),
objsession.s_QuestionMasterTopicInsert(topic.Title, contentId, new
DateTime(time.Ticks), topic.IsAvailable,
ref strRet,
ref strRetMsg);
But it gives following error:
SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM
Is it Possible to convert timespan to Datetime?
How should I save timespan at My backend as Datetime Field ?
The language I am using is C#.
I have the folowing dillema.
DateTime A, DateTime B. If A < B then I have to calculate the number of days per year in that timespan and multiply it by a coeficient that corresponds to that year.
My problem is the fact that it can span multiple years.
For example:
Nr of Days in TimeSpan for 2009 * coef for 2009 + Nr of Days in TimeSpan for 2010 * coef for 2010 + etc
I have this SP. When I run this one my calculations is only the first row in OrderDetails. I want it to calculate all rows

This works. But how can I calculate the avgerage speed if I have drived 665 kilometers in this time? I know how to do it with only houurs but not with the minutes to. I have tried this and I think it works. Is it correct?

I have events that have start and end dates and I want to display the current week that the event is in progress. To currently do this I am finding the week of the end date and subtracting the week of getdate(). This works unless the event goes into the next year and then it returns 0 .Here is my sql
course_status_1 = CASE
WHEN
GETDATE()[code].....
What I need to happen is for an event with start date and end date in differnet years to calculate what week of the event get date is currenty in.
I am trying to store a SQL Server datetime into MySQL datetime field, but MySQL stores the date value as all zeros. I use this function to trim the fractional part from the SQL Server datetime, but get the same result when trying to store it in MySQL.

I would like to use asp.net c# to calculate the timespan for when a file was uploaded. Example, if i uploaded a file two weeks ago my text will say 'uploaded 2 weeks ago' or if i have upload a file 4 month's ago my text will say 'uploaded 4 months ago'
View 2 RepliesIn the code i have :
gvRankings.DataSource = rankings.OrderBy(rg => rg.Swimtime).Take(100).ToArray();
gvRankings.DataBind();
(Swimtime here is a timespan)
At the frontside i have
< asp:TemplateField HeaderText="Tijd" ItemStyle-CssClass="time" HeaderStyle-CssClass="smallheader">
< ItemTemplate><%# ("Swimtime")%>< /ItemTemplate>
< /asp:TemplateField>
I would like to format the swimtime like hh:mm:dd.ff but i have (after 2 hours of trying) absolutely no idea how to do this.....
I have created a small asp.net application that allows users to reset their passwords. I am able to retrieve that last time the password was reset from the Directory Searcher object, but I'm having trouble with checking the timespan since the last password reset. The users can reset their passwords again after 24 hours have passed, otherwise they well get an error stating that they are not able to update their password at this time. Any recommendations on how to best go about doing this?
string passwordLastSet = string.Empty;
passwordLastSet = DateTime.FromFileTime((Int64)(result.Properties["PwdLastSet"][0])).ToString();
I have a calculation that takes place utilizing the TimeSpan.FromTicks method, the result is stored in a TimeSpan object. The calculation itself is working correctly, but I'd like to format the result a bit nicer than it is and I can't figure out how to format a TimeSpan.
The result from the TimeSpan is:
00:00:04.6153846
I'd like to remove any preceding zero's and round up to the second decimal place, such as:
4.62
Does anyone know how I might be able to accomplish this? I can't seem to find a .NET 'built in' solution.
I need to convert a timespan into an integer. I have two dates that I am subtracting one from the other, returning a value in days. I then need to perform some arithmatical functions on that value but I cant figure out how.
View 5 RepliesI have a timespan ts that has mostly minutes and seconds and sometimes hours. I'd like to format a string that'll give these results depending on the data
3:30 (hours not displayed, showing only full minutes)
13:30
1:13:30 (shows only full hours instead of 01:13:30)
So far I have
string TimeSpanText = string.Format("{0:h\:mm\:ss}", MyTimeSpan);
but it's not working.
I would like to declare some properties of my View Model of type TimeSpan to display the TotalMinutes property and bind back to a TimeSpan.
I've bound the property without using the strongly-typed helper in order to retrieve the TotalMinutes property:
<%=Html.TextBox("Interval", Model.Interval.TotalMinutes)%>
When the field is bound back to the View Model class it parses the number as a day (1440 mins).
How can I override this behaviour on certain properties (preferably using attributes on the View Model itself)?
So I've got entities set up with Entity Framework that have some properties of types String, DateTimeOffset and TimeSpan. For performing validation on the Strings, I've used fairly straightforward attributes like "[Required]" or "[StringLength]", and the control used is a textbox.
My issue now is for the DateTimeOffset and TimeSpan, I'm uncertain what control to use, but even more uncertain about what attributes to use to validate the input.

I have a column as totalsecond in my database i take a avg of tht totalsecond column for the particular parameter and condition and when i come on my aspx page i show that data as hh:mm:ss by converting it with timespan function of dotnet and show this in datagrid but while doing this calculation in DataGrid_ItemDataBind it take so much time and the user have to wait for long time for the result after clicking button show when there is large amount of data.
How can i reduce the time of waiting for the user with some coding logic that speed up the calculation time.
I am simply trying to determine age from a selection of Month, Day and Year representing birthdate, which I have captured from three drop down list boxes, by subtracting the studnetBirthDate from Today. How can I get Age? Using a calendar to select birth date seemed too clumsy because of the year navigation, age ranges from 3 to 26 yrs old. If anyone has a better idea I would be open to that as well. Instead I am using three dropdown boxes, one each for day, month and year.
Dim studentBirthDate
As
Date
Dim stMonth
As
String.........
I want to record the time and date when a user login to my system..How it is possible?..I want to get date and time and want to insert it into a database table.
View 4 RepliesI created a UserControl and added a public DateTime property. I want to set this property in Markup (ie. <cc1:MyControl runat="server" id="MyControl1" DateTimeProp="1/1/2010" /> ) however I live in a place with a dd/mm/yyyy date format so it complains if I set something like "20/1/2010". Is there a way to set markup in my local datetime format or do I have to conform to "mm/dd/yyyy"?
View 2 RepliesI want to have a total in the gridview footer of the duration of the employees. As the rowdatabound goes through the cycles I can see it reading the correct times from each row but it is not totalling in totalTime and I get 0:00:00 in the footer.

I have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)
I have an XML string which contains Dates formatted "dd/MM/yyyy hh:mm:ss".
I'm loading this XML into a dataset using DataSet.ReadXml().
How can I ensure that this Date is stored in the DataSet as a typed DateTime so that I can Sort, Format and RowFilter on it accordingly.
My test harness is as below:
ASPX Page:
[code]....
obj.From = DateTime.Parse(txtFrom.Text, ci);
And it will give error String was not recognized as a valid DateTime. How it can be solved..
