I want to get clients Time Zone offset from his IP address for my web app. I have tried using Javascripts getTimezone function, but, some clients have their timezone or time set incorrectly. I want to get the offset and render some information back on client based on their timezone.

I want to know about some FREE web service to which i give the ip address as the input and it will return with the Location info(e.g. Country,State,City etc) ,Language info (e.g. en-US,fr-FR etc), and the TimeZoneOffset (with respect to GMT) for the corresponding ip address. I also want this web service to handle DaylightSaving issue properly for any place in the world.
View 6 RepliesI have a client side JavaScript that generates a date in JavaScript( new Date(2007,5,1)).
I need this date passed through to a hidden field that the code behind can access.
My issue is that when the hidden field is converted into a DotNet datetime, the time is incorrect. This is because the JavaScript is including timezone info from the client browser.
DotNet is then using this info to recalculate the time based on the difference between the server time and the client time.
What i need from the JavaScript is just the year, month and day.
I don't want to pass through 3 int values to my code behind as this will be a major change to the whole app.
What is the best way for me to accomplish this?
If i can set a UTC time with no timezone info I think that might work.
i am designing a website in which i need to generate an offset value for a product(and store it in database) between 1 to 999 for every product id i store into my database from a textbox..but first it must check if a particular value starting from 1 to 999 is already taken if yes then it generates the next available number between 1 to 999..the problem is how can i retrieve and check the available numbers already stored in offset column of my database and then generate next available number?for example: if 1 ,2 ,3 ,6,8 numbers are taken offset value generated should be 4 and not 7..though its difficult to explain but if u understand my question i wuld be glad to have some code of how to achieve it??
View 1 RepliesI was reading this article about relative time calculationThe problem is that the results are wrong due to the time offset. My webpage is Greek.So how should i modify that function to work correctly, including the GMT+2 or GMT+3 hours offset?
View 2 RepliesIs there anyway in .NET to get an image offset position in the webform?Javascript can get this information from the "offsetX" and "offsetY" values but are there anyway to get the same info in .NET?Or can I use javascript to catch the info and send it to the backend? Like creating a hidden input field with the data and then read the data from the code behind?
View 1 RepliesI have a bunch of events with their location being pulled from the db and I am doing the following:
List<Place> placeList = new List<Place>();
foreach (var item in eventsList)
{
bool coordinateExist= placeList.Where(x => x.latitude == item.Latitude && x.longitude == item.Longitude).Count()>0;
Place place;
if (coordinateExist)
place = new Place() { title = item.Title, latitude = item.Latitude+0.0001, longitude = item.Longitude};
else
place = new Place() { title = item.Title, latitude = item.Latitude, longitude = item.Longitude};
placeList.Add(place);
}
I have a slight issue though. If two locations have the exact same latitude and longitude I want to offset the latitude by the slightest amount (equiv to a few meters maybe?), and then add it to placeList. Hence I will have a list full of unique coordinates.
how can i achieve this nicely? The above works but not nice IMO

View 1 RepliesI don't see any properties, but thought I'd ask to see if there way to increase the width of the shadow or offset of shadow from the pop-up panel or div I'm displaying?
I just want to make the pop-up appear to "stand-out" a littlle more.

My ComboBox is now rendering its button and results list on top of the ModalPopup panel
[URL] However, the results are showing up completely separate from the textbox. This is bacially the same problem described at [URL] However, forcing the position of the list did nothing and I'm already using the very latest (release) build of the toolkit (so alaa9jo's post about it being fixed in the November 2009 build isn't true for my instance).
I need the combobox functionality for my form.
why the scrollbars in comboboxes choose to show sometimes and not other? My main combobox is missing them, but the combobox reference above has them. Both use the same CSS settings and databindings; the only difference is that the one with scrollbars is inside the ModalPopup.
I am generating a list of labels with an Image Button control at the start of each line. Unfortunately, my browser displays this list on a web page with the image higher than the label text by a few pixels. This results in a blank line of a few pixels wide between each line of text. Even the image has a blank line above it. This especially puzzles me since I went to the trouble of specifying the height, in pixels, of the image and labels. Is there any way to make the image and text appear evenly on the same line?
View 2 RepliesI have placed an AJAX Control Toolkit (version 3.0.30512.1) HTMLEditor inside a ModalPopup. Everything works fine except when you click the 'Insert/Edit URL Link' button. The resulting 'add a link' popup moves to the extreme bottom right of the ModalPopup - and drastically shifts the HTML Editor. This happens in Firefox, IE8 and Chrome so far. A screenshot to illustrate this is shown at the bottom of this message.
Secondly, as you can also see on this screenshot, there is a lot of white space below the HTML Editor before the Horizontal Rule - there are no other HTML tags between the HTML Editor and the Horizontal Rule. This space only 'closes up' if I increase the height of the HTML Editor - it does not reduce automatically.
I am making a page that accepts post data from any number of pages that I cannot change, access, or in any way control.
I need, in one way or another, to get the timezone of the user. I know, ideally the posting page would do this, but I cannot access these pages.
First, there is javascript. I can get the javascript function to return (or change a label to) the correct value, but the problem is I need this info before the postback. I've been trying to write the timezone name on another page and read that page, but I have no idea how to begin to do that? Any other workaround to use the javascript is welcome, or any way to force call this before Page_Load is called?
[code]...
Basically, this works in debug mode, but when it's live only an empty string is returned. I am baffled? Is there any better way to read data from a page? I am using Request.ServerVariables["REMOTE_ADDR"] to get the ip, and that seems to be correct, since it inserts the correct ip into the database I'm using.
Here is the call:
GetTimezone(Request.ServerVariables["REMOTE_ADDR"]);
I have an ASP.NET web application that requires users to select their appropriate time zone so that it can correctly show local times for events.
In creating a simple approach for selecting the time zone, I started by just using the values from TimeZoneInfo.GetSystemTimeZones(), and showing that list.
The only problem with this is that since our application is primarily targeted at the United States, I'd like to show those entries first, basically starting with Eastern Time and working backwards (West) until I reach Atlantic time.

View 1 RepliesI'm building an ASP web app that stores appointment times; it'll be used in different timezones. I'm currently saving an appointment in the database as a datetime field. Do I also need to add a field to save the timezone ? What's the best option to solve these multi-timezone issues?
View 1 RepliesHow do I write a timezone converter library in c#? or is there an existing timezone class I could use?
I will need the timezone database and be able to use it to calculate/convert from one UTC timezone to another timezone.
for some reason when I use the following code
TimeSpan timeDiffUtcServer = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now);
it returns -07:00:00 offset
I am using Windows XP and my timezone is set to Pacific time -08:00. I am running this through VS 2010's built in IIS server which is on my computer, so I can't figure out why the discrepancy in time.
I'm trying to write cookies from my website and I'm trying to figure out what implications timezones has over the HttpCookie.Expire property. Should I be passing DateTime.Now.AddDays(1) or DateTime.UtcNow.AddDays(1) or the users's timezone plus a day?
View 1 RepliesWhen a post is made to the site/database, it's made as Universal Time. A user can set the site's default timezone from a dropdown menu in the admin area, which saves the selected timezone to a database table (table: DefaultTimezone, column: Timezone). Now, how can I adjust the following code to display the datetime according to the correct timezone, that was set in the database? So if the Timezone column has "US Eastern Standard Time" in it, it would display the published datetime in that format.
<%#Eval("Published", "{0:MMM dd, yyyy - h:mm tt}") %>
If my user is in California and they have their computer set to PST, it's 1:00 pm there. If my server is set to EST, the current server time is 4:00 pm.
I need a way to get the timezone difference between the client and the server, either in Javascript or C#. In my example, I would get 3 (or -3, doesn't matter).
Does anyone know how to do this?
EDIT: Possible solution for RedFilter
Doing it all in javascript:
serverDate = new Date('<%= DateTime.Now.ToString() %>');
clientDate = new Date();
diffMin = (serverDate.getTime()-clientDate.getTime())*1000*60; //get difference in minutes
