.NET Column: Run-time Serialization, Part 3


This is the third part of my three-part series on serialization. In part one, I showed how to serialize and deserialize objects. I also showed how to define types that allow instances of themselves to be serialized.

Data validation on a datetime column - or remove date part and only keep time part of the datetime2


Windows Server 2003, SharePoint Designer 2007, Windows SharePoint Services 3.0

I have a calendar list with start date(datetime1) and end date (datetime2).  Each is the default column created by the calendar list in SharePoint.  They both display a date and a time to choose from.

QUESTION:  Is there a way to remove the date section of the end date in a custom list form so that the user can only pick an end TIME?  Or, is there a way to force the end date (datetime2) to HAVE TO BE the same DATE as datetime1, only allowing for a different time?

Thank you!

Trying to set Calendar Time Interval Using Calculated Column, but getting Error



So i was trying to use a calculated column that added 7 days to the start date of a calendar item. The calculated column worked fine because i checked with several tests. Then i tried using the Column as the End Time in the Time Interval Setting in the Calendar View. This broke Sharepoint. Not the normal graceful error im using to seeing from Sharepoint but the Server Error Page when a dump happens in a ASP page. I havent enabled the full error page because i assume its not like i can fix it, i dont have the source code.


Does anyone else experience this? If so is it a known problem and being worked on?




Use Sharepoint Calendar Start Time field in calculated column

I'm trying to limit the calendar view to current week using the Sharepoint defined field Start Time. However, when I display the serial number behind the Start Time it looks like it is actually giving me the serial number for the Created Date field. I believe it is because the appointment is reoccurring but I'm hoping there is a way around it. I created a new testdate field and manually entered the date and set those appointments as all day events however they are not reocurring appointments. The testdate returns the correct serial number however the start time returns an incorrect serial number. SerialNumber1=DATE(YEAR([Start Time]),MONTH([Start Time]),DAY([Start Time])) SerialNumber2=DATE(YEAR([testdate]),MONTH([testdate]),DAY([testdate])) Start Time  SerialNumber1 Testdate  SerialNumber2 8/31/2010 40420 8/31/2010 40421 8/31/2010* 40405    9/1/2010* 40405    9/2/2010* 40405    9/7/2010 40427 9/7/2010 40428 9/13/2010* 40405    9/14/2010 40434 9/14/2010 40435 9/14/2010* 40405    9/15/2010* 40405    *These are reoccurring appointments scheduled as all day events. The others were entered as one time appointments scheduled as all day events.

Weird Date vs Date/Time issue using a calculated column

I'm attempting to use the fab 40 attendance template. I don't need the time to show - Im able to hide that on the forms with jquery (endusersharepoint.com thank you!!) I WAS ATTEMPTING to create a calculated column called Start Date where the formula simply reads '=[Start Time]' When it's set to display 'Date Only' the date is off by a day. If I switch it to 'Date & Time' I get the correct date. Huh?

datagridview add data a column at a time

How do I add to a datagridview a column at a time? I see at http://msdn.microsoft.com/en-us/library/5s3ce6k8.aspx that it is possible to do it a row at a time. I was looking for something similar.      

Calculated Column: Text ==> Date and Time Column (Date+Time)





I have a little question about calculated columns in WSS 3.0 (not MOSS 2007)


How can I have a calculated column which is a Date+Time based on a text_column

Converting YYYYMMDD_HHMM (time = 24 hour format) format  ==> Date+Time



20070629_0848 converting to 29/06/2007 08:48


==> I have already a formule, but with teh DATE(...) function, you cannot give the hour-minute-seconds as a parameter, so the time is always 00:00 in WSS 3.0 (and yes, i have selected date+time as result-type for the column)


Is this possible in WSS to calculate a full date out of a text, maybe if i use two seperate text-columns, and convert a to date and one to time and a third which combines the two...


It would be a huge help if somebody could give me som advice to calculate a full date+time out of one or more text-columns....





Workflow SPD: Set Today Date+Time to Column-field




I have a little question about settings specific today (Date + Time) value to a field/column within a workflow that is designed by Sharepoint Designer 2007.


I can manage to set the field to today() => but the time is always 00:00 houres.

I would like to set a specific field to the "exact" date+time when the workflow is running. (so choosing a fixed date+fixed Time isn't a solution either)


So I anyone could help me how I can do such "simple" task, I would be very pleased.

Only date is displayed in modified column. How do I get it to show time also?


I can't find out how to set the format for this column in document libraries. I have seen the column also display time so I know it's possible.



How to retrive a date time value from TimeStamp column using Linq?


I have a Timestamp column in my Table. I want to read the date time value and display in UI.

In Linq the Timestamp column is represented as System.Data.Linq.Binary.

I dont know how to retirve date time value in "MM-dd-YYYY" format from this Linq.Binary


- Why I am using Timestamp?.

I want to perform some operations based on the last modified date time of the particular row. Since I am using TimeStamp column in my Table as version column, It will contain the last modified date details, So i want to read the date time value from this time stamp column to do some other operations.



"Date&Time" column in list - set actual time and sharepoint's proposes wrong hour (eg. 17:00 instea


I created new column in list - Date and time (Date and time format: Date&Time, Default value: Today's Date)

The problem is, when I create new item in list, the default time is always set as next full hour, eg. now it's 13:15 or 13:31 ora 13:57 and in aspx form it's all the time 14:00. Obviously, I can change that date with 5 minut precision (13:05, 13:10, 13:15 etc.), but it's kind of annoying.

Seperate DateTime into Date column and Time column in query


This is probably a simple question but here it goes.

First off let me state that the naming of these columns is not by my choice nor can I change them.  We purchased some software that automatically does the naming conventions for it's fields (Sample1).

I have a table with 2 columns in it:

Sample1                      Time is in GMT Time

Time           DateTime, PK        

LMP             Float

Table 2:

ABC_Price                   (Day, Hour) is in EST Time

Day               SmallDateTime   PK

Hour              TinyInt       PK

MW                Decimal(7,3)

Price              Money
