Databases :: Convert Totalseconds To Hh:mm:ss By Converting It With Timespan Function Of Dotnet?
Nov 16, 2010
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 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 ?
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.
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 two questions, could anybody please answer to those:1) Do I need to install Dotnet framework 2.0 if dotnet framework 3.5 is already installed on the same server?2) Also do I need to install "ASP.NET 2.0 AJAX Extensions 1.0" if higher version is installed on the same server?
I'm trying to add a parameter at the end of a url obtained from the database as follows:
This is giving error because of the ID value, which is an integer...how can I convert it to string here? I can do it in code behind, but I just want to know how it can be done within the Eval function...
I have a column in sybase database with image datatype which stores some message information. I want to convert back to text when presented to the user. how do I do it in the Client side? if someone has any suggestion or related code.
I'm really stuck tryign to figure this out. Converting XLS to CSV is no big deal or at least it seems that way. However, trying to go xlsx to csv seems to be more difficult. For grins, I grabbed some code that is supposed to read a sample xlsx file and convert that into a gridview called GridView1. I figure it can't be much different to turn that into CSV.
I am trying to use the MySQL replace function in C# but the resulting data ignores the columns inside the REPLACE function - i guess its because C# has its own Replace function
get the required column either through Mysql escape sequence or in the C# syntax
MySqlConnection mySqlConnection1 = new MySqlConnection("server=localhost; database=faohr; pooling=false; allow zero datetime=yes;");
I downloaded the OracleHelper.cs & I use VisualStudio 2008,I'm suppose to pass values to a stored procedure which accepts 2 parametersWhen i pass from codebehind it says,
I am continuously getting error for following line of code. It work fine in other Database. ERROR [S1000] [Microsoft][ODBC Visual FoxPro Driver] Function name is missing. Am I doing any mistake [Code]....
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 am developing a webaaplication ASP.net using C# and MYSQL as backend..
i am facing problem to execute this query in MYSQL:
SELECT ID, Date, Event, Remark, school, section, class, schooltype, shift FROM sessioncalendar WHERE (school = 'SECONDARY SCHOOL') AND (class = 'IX') AND (section = 'B') AND (shift = 'SHIFT I') AND (schooltype = 'XYZ School') AND MONTH ( Date )= '6'
AS the query works well wethout addind AND MONTH ( Date )= '6' ... but when i add this line query generate error
( Error in list of function arguments: ')' not recognized. Unable to parse query text.)
While same query is working successfully with Sql Server 2005...but i hvnt found any reason why my query is not working with Date(datetime) column..i hv google about it..but i found synatax is same in both SQL SErver 2005 and MY SQL syntax
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
My title says it all, I am looking to see if there is any built in class/function that basically takes a number and gives back the number in letters such as 10 to ten.
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'
