I have a web page that has a textbox for users to enter a datestring to check against a database. The database that I am running my query against has datetime values set at minutes since 12/31/1899 and that returns a timestamp. What I'd like to do in my code is to convert my textbox entry into minutes since 12/31/1899. Does anyone have an easy way to do that?
View 1 RepliesI have a Timestamp column in my Table. I want to read the date time value and display in UI.

I have searched a few pages on this (including MSDN) but have not quite reached a solution. I need to convert "16/04/2010 22:39:06" to "2010-04-16 22:39:06.034" (for example).
I have already written an SQL function to do this, but would rather do this in VB.NET if possible. The date value is coming from the Date Created information of a newly uploaded file:

How can I easily convert to the needed format?

i currently use the context.timestamp function to get the time in the beginning of the request but i want to know if i can check the time sooner in the pipeline (before the load page phase) or the timestamp is the earlier time i can get. now i need to find the latest time after the request was processed, of course i can check the time in the end of the function, but is there somewhere else where i can check the time of the request ending.

But now i'm binding it from client side through WebService which has no such "onClientTimeSlotCreated" event, also these time slots are not having any identity at client side to access.
