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 ?
in my application two time input will be passing to my sql stored procedures and I need to calculate the timespan between them. how can I do that? is there any way that I can do the following in t-sql?
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.
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.
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 am displaying some news from rss feeds in the page. But i am stuck up in the date time conversion. I got th published datetime as pdt formated string. How can i convert to my local time. Coversion from the pdt string tot DateTime is error..
[Code]....
This second line is error and i need the result in the specified format or same format as in the published date but in local time ie IST (India Standard Time)
i have string like "30/03/2010 12:03:15:PM" i want to covert in date time how it possible?to convert i got this error "String was not recognized as a valid DateTime."
I have stringarray called Timesplit with time like(17:00-2:00).How to store Timeplit array values into datetime array value.I am having 7 values that's why i am using TimeIn[arrayIndex].I will increment arrayIndex for 7 times for 7 timeIn.
I am getting error while trying to store TimesPlit[0] to TimeIn[arrayIndex].I want 17:00 into TimeIn[arrayIndex] and 2:00 into TimeOut[arrayIndex].If i use datetime will get date also so give me better options to store TimeIn and TimeOut.
I have a column in my datatable which is of DateTime Type. I only want the DatePart, hence when I use the ToShortDateTimeString it converts to short date but of string type. Hence when i reassign the string to the column of the datatable it again appends 12:00:00 to it. I cannot change the column type in my datatable. Is there any way to convert DateTime to ShortDateTime directly without converting to string?
dim str as String = textbox1.text ' when date is in this format dd/MM/yyyy dim date_time as Datetime = Date.ParseExact( str , "dd/MM/yyyy" , nothing)
it works fine but when the user but the date like this 9/9/2010 it gives error because the format is set "dd/MM/yyyy" and given date format is "d/M/yyyy" or it could be "dd/M/yyyy" what could be the solution of this problem?
I have date in a text box in the following format "dd-MM-yyyy"How do i convert this into standard datetime format, i could do DateTime.Parse(txtDate.Text).Date but how do i define the current format of this date before parsing, i mean how do i tell the parser that this date is currently in the format "dd-MM-yyyy" usualy parser assume date to be in "MM-dd-yyyy" format i guess?
I have written a code to insert emp details into database and i am also inserting local date(i,e system date) into to the table to know/have an idea at what date the employee inserted details. I have set date format add/MM/yyyy and its working well in my local system, but after uploading the site into server (the server is shared server) iam getting error and the error message is Failed to convert parameter value from a String to a DateTime.
Surprisingly, it is working well in server when i chaged the date format to MM/dd/yyyy, but now its not working in my local system and getting the same error.
I've been googling for a while now and for the life of me can't seem to find a solution. I thought this would be easy but it's taking too long and am turning to stackoverflow.
I need to convert a string which contains a date and time to a DateTime variable. I've formatted the string in the exact format I want to store it in but when i convert it to a DateTime it keeps adding the seconds which I don't want. I want it stored as 01/01/2010 09:00AM. Here's the code I've been using so far:
q="select convert(char(8),datecol1,112) from tblone where datecol2 is null"
is what I use for my query string for sqlcommand(). I'm getting the error "a field or property datecol1 could not be found in the datasource". Without the convert, the query is ok.
note MONTH AND DATES stored in single or double digits as they occur. Unfortunately DATE TIME is stored in NVARCHAR Data type column as 2/9/2010, 22/10/2010 etc. Following UK Date here. It is required to pull the data to COUNT No. of Expired. Obviously below one fails.
I have one class for selecting, updating and deleting record in db (sql server 2008) and one class for represent table record, i think it's call 'Activ record' design pattern. Now, I have GriwView with editing, selecting and deleting items. Data source for this grid is ObjectDataSource:
Currently I am able to bring the datetime from my SQL table but I also need the milisecods. Here is the line of code:
[Code]....
So latestTimeStamp = {9/22/2010 6:24:09 PM} but I needed it to be latestTimeStamp = {9/22/2010 6:24:09:080 PM} since the SQL field value is 2010-09-22 18:24:09.080 and I want to do an accurate datetime comparison.
