C# - Check For New Data After A Certain Time Frame?
Mar 31, 2011
Right now I'm using a 3rd party provider to get some data. Every time I call the service I need to pay a small fee for the data. I'm wondering if there is a method in sql or c# that can store the data in a personal database, then check (after a specified timeframe) whether or not there is new data at my 3rd party provider.
For example, instead of "calling the service"/"looking for the data" each time the page is loaded, I'd like to look for new data every week or so and store the data on a personal database to use for the next week. This helps me cut on the costs and also speeds up my system.
I'm not looking for any code here, just a simple way to execute/problem solve. My tools are VS, c#, SQL, asp.net/html.

I have this situation where I have three pages:
The first page, default.htm, is a frameset page that uses the other two pages.
The second page, casemenu.aspx, is a form that contains an object we call "PopupManager": It has an element <xxx:PopupManager runat="server"/>. This object is dependent on the standard ScriptManager, which requires a form.
The third page, header.aspx, contains three links. Each link calls a JScript function that in turn calls a function on the Popup Manager. It makes the call to the popup manager with an expression like 'top.frames.casemenu._PopupManager'.
Now, the problem I have is that I have to change default.htm to be a normal page containing an iframe, which will refer to a new page, container.aspx, which has the original frameset. When I do that, I can no longer access the PopupManager the same way ('top.frames.casemenu._PopupManager' no longer works.)
I would like some way to refer to the PopupManager relative to header.aspx, something like "self.parent.frames.casemenu._PopupManager", but that doesn't work.

I am developing a website in ASP.NET with SQL SERVER as backend.
I want to find the best(FASTEST) way by which I can find if USERNAME exists or not.
My application is taking a bit of time finding that out. Do I need to look into my TABLE structure,indexes.
Is there any replacement for the query
Select username from usermaster where username=@Username

I have a gridview with entity frame work datasource. When editing or deleting I get Store update, insert or delete statement affected an unexpected number of rows(0). I selected * from the datasource. I made a template field to show the posts. There is a PostId in the framework. I am guessing that the PostID is not bound to the gridview the problem and the fix?

I am writing a chat application, in which a chat starts in a chat room. Now, i want this room active only for a certain amount of time and not more. i.e 1 hour etc. So, to check the time constantly what and how should i write something in the background, so that when the time is over, the sessions of all the users logged in at that chat room get destroyed. And the users are again redirected to the login page. e.g The chat has been setup from 3 to 4 pm. At 3.55 everybody should be given a popup that the chat will end in 5 mins. And at 4 everybodys session should be destroyed and they should be redirected to the login page.

Specifically we're making our application compatible with the Out Of Process Session State server where all types saved in session must be serializable. Is there a way to see at compile time that any type put into HttpSessionState is marked with the Serializable attribute. Something along the lines of this 'non-valid' code
public static void Put<T>( string key, T value ) where T : IsMarkedWitheSerializableAttribute
{
HttpContext.Current.Session[key] = value;
}

I have a table(ShiftCalendar) that lists a letter and a datetime:
Shift Date
A 3/2/2010 8:00:00 AM
B 3/2/2010 8:00:00 PM
I can run a select query that looks like this:
SELECT Shift
FROM ShiftCalendar
WHERE (Convert(nvarchar(10), GETDATE(), 101 = Convert(nvarchar(10), Date, 101))
This will return both values, but I need to to check the time of day to determine which Shift to return. I have been messing around with the IF ESLE and CASE but I can't find a way to tell the select statement what the time of day is.

I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.

how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.

I have the above query and that gives me result
Emp_code EmplName Punched_date Punched_Time
4 XXX 3/27/2013 14:22:00, 09:44:00, 10:38:00, 11:01:00, 16:12:00, 18:25:00,
4 XXX 3/28/2013 13:14:00, 09:49:00, 18:02:00,
Now i need to Bind it to gridview, the gridview columns should be
Date,IN,OUT,IN,OUT
In punched time the first one should be IN and second OUT. A employee would have punched several time a day. Based on that I should take maximum punches and bring that of columns as IN and OUT in gridvew dynamically. How to achieve this?

This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then
Try
If pasDate <= System.DateTime.MinValue Then
Return Nothing
Else
Return CType(pasDate, DateTime)
End If
Catch ex As NullReferenceException
Return Nothing
End Try
Else
Return Nothing
End If
End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.

I have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.
