Is there an ASP.NET Script to allow a specific webpage to be access only in a specific time of the day in the week? for example: in a course you want your students to access your webpage in your network in a certain hour of the day and the week!
Update:Answer cannot be no.i have an example from a site:www.codeforces.com
In this site in specific time,contest is running and codeforces allows a page on that time.
On your page_load you could have something like this
if (!IsAllowedTime())
{
Response.Redirect("/ComeBackLater.aspx");
}
Where within IsAllowedTime you would validate DateTime.Now against your time restrictions

Does anyone know how I should define a transit service that only occurs on public holidays, in GTFS?
calendar.txt as;
'4,0,0,0,0,0,0,0,20161211,20171209'
calendar_dates.txt as;
'4,20171001,1'
'4,20171002,1'
'4,20171225,1'
'4,20171226,1'
This apparently does not seem to work... My dataset also contains normal regular services, and they work fine.
Populate calendar_dates.txt exactly as you have shown above and put nothing in calendar.txt for service id 4
This is permitted by the spec, see
https://developers.google.com/transit/gtfs/reference/#calendar_datestxt
and I suspect that inserting an entry into calendar.txt with none of the days set to 1 is confusing validators.
You need to both add new service and cancel the service
In this case, New Year’s Day is added as a Sunday schedule (exception_type 1), with the existing weekday schedule cancelled out (exception_type 2).
In calendar.txt:
service_id,monday,tuesday,wednesday,thursday,friday,saturday,sunday,start_date,end_date
weekday,1,1,1,1,1,0,0,20140101,20240101
saturday,0,0,0,0,0,1,0,20140101,20240101
sunday,0,0,0,0,0,0,1,20140101,20240101
In calendar_dates.txt:
service_id,date,exception_type
weekday,20140101,2
Sunday,20140101,1

I'm developing an asp.net mvc3 project. I have a trouble in this problem that I encounter. I will give a scenario so that it will understand well.
Scenario:
I have 2 PC (PC1(server) and PC2(client)). For example both two PC has different date and time let say for PC1 is +8GMT Date 8/10/2016 and for PC2 +8GMT Date 8/9/2016. I am using the PC2 the client and i'm using a code for getting the time is DateTime.Now(); in my controller and the time is display in label in one of my views. I tried to adjust the Date and Time of the PC2 the label for displaying t he time also change. What I want is even I change the Date and Time in PC2 it won't affect/change the displayed Date and Time in my label it will stick on what the Date and Time in the PC1.
This scenario is i'm using/testing the publish project
Any suggestions are welcome.
I'm not sure if I understand the question, but you might consider looking into the DateTime.ToUniversalTime method, which converts the value of the DateTime object to UTC.
This way, you may be able to work with a standard time from which you can convert to any time zone you might want to use to display in your application, regardless of server location.
DateTime serverTime = DateTime.Now;
DateTime utcTime = serverTime.ToUniversalTime;
string timeZoneId = "some time zone id";
TimeZoneInfo myTime = TimeZoneInfo.FindSystemTimeZoneById(timeZoneId);
DateTime label = TimeZoneInfo.ConvertTimeFromUtc(utcTime, myTime);
I am not very clear on your description. It seems as if you want your label to always show the time on the server (PC1) when the web page is loaded on the client by calling the site on the server, maybe like https://pc1. What you're doing should accomplish that: the time displayed in your label will be the system time from the server. Changing the time on the client will not affect it.
If you want your client (PC2) to show its local time, you will need to use code that runs on the client, i.e. JavaScript in most cases.
Working with dates in Javascript can be a little different from other languages/expectations, so I suggest reading the docs at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date.
Get started with var currentDate = new Date();.
I am using ASP.NET MVC 3 to track hits on a set of stored links. I run into problems when displaying the hits' counts. I think this is because since I am using lazy loading, whenever I call
link.Hits.Count
it loads all of each hit's data, including such things as agent and referrer information. (Hits is a Collection.) This is an issue when a link has over 9000 hits. Is there a way of just getting the Hits' Count without it pulling in the Hits' data?
If the Hits has been written like this, the Count will work:
Hits = repository.GetAll(....).Where(....);
But if like this, the Count will not work, because the ToList() has already loaded all the data:
Hits = repository.GetAll(....).Where(....).ToList();
guys!
I'm developing an online auction with time limit.
The ending time period is only for one opened auction.
After logging into the site I show the time left for the open auction. The time is calculated in this way:
EndDateTime = Date and Time of end of auction;
DateTime.Now() = current Date and Time
timeLeft= (EndDateTime - DateTime.Now()).Seconds().
In javascript, I update the time left by:
timeLeft=timeLeft-1
The problem is that when I login from different browsers at the same time the browsers show a different count down.
Help me, please!
I guess there will always be differences of a few seconds because of the server processing time and the time needed to download the page.
The best way would be to actually send the end time to the browser and calculate the time remaining in javascript. That way the times should be the same (on the same machine of course).
Roman,
I had a little look at eBay (they know a thing or two about this stuff :)) and noticed that once the item is inside the last 90 seconds, a GET request gets fired every 2 seconds to update the variables in the javascript via a json response. you can look at this inside firebug/fiddler to see what it does.
here is an example of the json it pulls down:
{
"ViewItemLiteResponse":{
"Item":[
{
"IsRefreshPage":false,
"ViewerItemRelation":"NONE",
"EndDate":{
"Time":"12:38:48 BST",
"Date":"01 Oct, 2010"
},
"LastModifiedDate":1285932821000,
"CurrentPrice":{
"CleanAmount":"23.00",
"Amount":23,
"MoneyStandard":"£23.00",
"CurrencyCode":"GBP"
},
"IsEnded":false,
"AccessedDate":1285933031000,
"BidCount":4,
"MinimumToBid":{
"CleanAmount":"24.00",
"Amount":24,
"MoneyStandard":"£24.00",
"CurrencyCode":"GBP"
},
"TimeLeft":{
"SecondsLeft":37,
"MinutesLeft":1,
"HoursLeft":0,
"DaysLeft":0
},
"Id":160485015499,
"IsFinalized":false,
"ViewerItemRelationId":0,
"IsAutoRefreshEnabled":true
}
]
}
}
You could do something similar inside your code.
[edit] - on further looking at the eBay code, altho it only runs the intensive GET requests in the last 90 seconds, the same json as above is added when the page is initially loaded as well. Then, at 3 mins or so, the GET request is run every 10 seconds. therefore i assume the same javascript is run against that structure whether it be >90 seconds or not.
This may be a problem with javascript loading at different speeds,
or the setInterval will trigger at slightly different times depending on the loop
i would look into those two
In the Security model for out ASP.Net website (.Net 3.5) we store the page name:
page.GetType().Name
as the primary key in a database table to be able to lookup if a user has access to a certain page. The first time a page is visited this record is created automatically in the database.
We have exported these database statements to insert scripts, but each time a new page gets created we have to update the scripts, not a huge issue, but I would like to find an automated way to do this.
I created an attribute that I tagged a few pages with and then wrote a small process to get all the objects that have this attribute, through the reflection create an instance and insert the record using the same code to for page records mentioned above:
IEnumerable<Type> viewsecurityPages = Assembly.GetExecutingAssembly().GetTypes().Where(t => t.IsDefined(typeof(ViewSecurityAttribute),false));
foreach (Type t in viewsecurityPages)
{
object obj = Activator.CreateInstance(t, false);
//clip..(This code just checks if the record already exists in the DB)
if (feature == null)
{
Attribute attb = Attribute.GetCustomAttribute(t, typeof(ViewSecurityAttribute));
if (attb != null)
{
CreateSecurableFeatureForPage((Page)obj, uow, attb.ToString());
}
}
}
The issue is that page.GetType().Name when the page goes through the actual page cycle process is something like this:
search_accounts_aspx
but when I used the activator method above it returns:
Accounts
So the records don't match the in the security table. Is there anyway to programtically "visit" a webpage so that it goes through the actual page lifecycle and I would get back the correct value from the Name parameter?
Any help/reference will be greatly appreciated.
Interesting problem...
Of course there's a (too obvious?) way to programmatically visit the page... use System.Net.HttpWebRequest. Of course, that requires the URI and not just a handle to the object. This is a "how do we get there from here?" problem.
My suggestions would be to simply create another attribute (or use that same one) which stores the identifier you need. Then it will be the same either way you access it, right?
Alternatively... why not just use a 3rd party web spider/crawler to crawl your site and hit all the pages? There are several free options. Or am I missing something?
