I have an application that looks at the system time and records the datetime. We give out demos and license by time.
One customer claims to have blocked my application from seeing the time so it always runs. He wouldn't say how but just said he would "not let it look at the time." Before I dig into this has anyone heard of this or know how to do it? He's not really a hacker but is tech savy enough to find things other people have done.

Without knowing how you are looking at the time it's impossible to guess how he is blocking it.
One of these days I'm going to think of a really clever signature.

I'm just using
DateTime.Now.ToUniversalTime()
|
|
|
|
|
Have a look at: http://www.nirsoft.net/utils/run_as_date.html[^]
It hooks the API calls to read the system clock and returns a specified date/time to a particular program.

This is blocked at work but I'll take a look at it when I'm at home. Thanks,

At the min, any user can book a holiday for ay employee,
I have added [Authorization] to the controllers, and @if (User.Identity.IsAuthenticated)
in the layout so only logged in users can view the pages. But how can I go about only allowing users to book a holiday for them selves
something like if loggedInUserID(is this assigned automatically when a user is created?) =currentPersoID, although this is only a guess and I would prob have to assign the same loggedInUserID to personID.
any suggestions?
Thanks

This is still not the ASP.NET forum.

So at the top of my controllers i've added in [Authorize], So far so good only logged in users can access these pages (Person and Holiday)
However the tabs in the homeController which navigate the users to these pages are still displayed...coming from the layout.cs
<li>@Html.ActionLink("Home", "Index", "Home")</li>
<li>@Html.ActionLink("About", "About", "Home")</li>
<li>@Html.ActionLink("Person", "Index", "Person")</li>
<li>@Html.ActionLink("Holidays", "Index", "Holidays")</li>
How can I only get these tabs to display if a user is logged in.
I have tried the approach of adding in a bool in the AccountController.cs
else
{
loggedIn = true;
return RedirectToAction("Index", "Home");
}
}
else
{
loggedIn = false;
ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
but then how do I access this from the layout.cs?
Is this the correct approach. Please advise. thanks

Don't you think this would be more appropriate in the ASP.NET forum?

My website is using asp.net with c#. Recently i am adding a new function by adding a flash webcam photo capture. In local it can function well, it can capture photo, save into database, and display the photo. However, after deploy it cannot funtion well on my server. The webcam still can function. But it cannot convert and save that photo into database. I suspect the actionscript cannot fire... Do i need to install any flash player into my server? Anybody can help me? Pls help... Urgent. TQ

Does your database allow remote connections? Most hosted solutions have a firewall, preventing it.
|
|
|
|
|
Yes, i have opened all the access... Any other idea? TQ

I'd doubt that. Create a small test-page from where you open a connection to the database, and try with that.
Are you using a hosted solution, or is this your "own" server?
What does the page do? Does it show at all? Does it show an error? What error?
As a side-remark; Every members' question is equally urgent.

|

It does not show any error. When i click the "capture" button photo, the photo is captured. But does not save into the database...
|
|
|
|

Paste your database-save-code here, and we'll have a look. I assume you added an exception-handler to the example from the tutorial?

You'll have to debug the CreatePhoto method, and verify the contents of the variables. Also verify that the user has the correct access-rights to that folder.
A few remarks on the code;

I used firebug. It shows "500 Internal Server Error".

Good morning 
lhsunshine wrote: 500 Internal Server Error
That's a generic message, saying something went wrong during execution of the code on the server. There'll be an exception probably, but that should have shown in your text-file now. Unless, the user isn't allowed to write there. Perhaps it's easier to display the message using Response.Write. I'm not an ASP-programmer, but the code "looks" like it should run.
I'm guessing that something goes wrong either by decoding the picture from Base64 (try and save the raw data, might be a nice clue for debugging) or the users' rights. Easy way to check the latter is by creating a small test-page that writes a line of text to that location.

HAHA... Overhere now is night time...
My Log.txt file is worked. I have try to input other error. Log.txt has an error message. But now is no error shown. I think it never go to this page. This page is fire from the button "Capture" in flash. I suspect the action script in flash do not fire.

Hey Guys...so trying to get my head around MVC
My Index for holiday page is linked to the model
@model HolidayBookingApp.Models.HolidayList
Im trying to pull the value of Holidays remaining from the HList4DD (HolidayListForDropDown) which is coming from the HolidayList.cs page.
I can get it through...
@foreach (var item in Model.HList4DD)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.PersonId)
</td>
<td>
@Html.DisplayFor(modelItem => item.HolidayDate)
</td>
<td>
@Html.DisplayFor(modelItem => item.Person.HolidaysRemaining)
</td>
Although this displays the holidays remaining for every holiday booked. So if 20 holidays is the limit (4 booked and 16 remaining) this will produce a list of the dates of holidays booked i.e 4 records stating which date is booked, but it will show the '16' holidays remaining 4 times as well.
Yes, this is because it is inside the for loop but I tried to display it on its own and it didnt work
@Html.DisplayFor(model => model.HList4DD.//what do i add here?
Also tried to add
Person person = new Person();
currentHolidaysRemaining = person.HolidaysRemaining;
to the HolidayList. cs then in the view do
@Html.DisplayFor(model => model.currentHolidaysRemaining)
but its not pulling across the correct value, just returning 0
please advise....thanks
