View 1 Repliesi am trying to find distance by latitude and longtitude by using this formula mentioned in this site.
[URL]
every thing is Ok there when i do it by calculator but when i started doing it by programmatically there is a diiference in result.
here is my part of code
lat = Convert.ToDouble( (s3[a]));
longt =Convert.ToDouble( (s4[a]));
Avg_lat = pc._Latitude - lat;
Avg_longt = pc._Longitude - longt;
a_hold =( Math.Sin(Avg_lat / 2) * Math.Sin(Avg_lat / 2) )+ (Math.Cos(pc._Latitude) * Math.Cos(lat)) * (Math.Sin(Avg_longt / 2) * Math.Sin(Avg_longt / 2));
c_hold = 2 * Math.Atan2(Math.Sqrt(a_hold), Math.Sqrt(1 - a_hold));
// c_hold = (c_hold * 180) / 3.12;
distance = 6371 * c_hold;
the problem is Math funcation here calculate the things in radian i want it in degree. so i just found a formula to convert radian into degree but that formula does'nt convert the calculation correctly..
what to do bcoz there is'nt any other option to convert radian into degree..
my site I want to calculate the distance between two areas of same city.Like I am using a search criteria where I have a drop down list. In which options are as below.
100km-70km
70km-50km

When user selects any one of the options the schools or shops in the specified area should be displayed. Is it possible to dynamically calculate the distance,
Im looking for the functionality seen in most commercial websites like google maps to get approximate distance between cities and zip codes. Im guessing these sites are using huge databases with all this information already in them. It would be interesting to learn how to create this functionality myself but Im sure that would require a great deal of time. So Im looking for a package where someone has already done the work(an API) that would allow me to enter two different zip codes or maybe two different city,state combinations and take actions from there.
View 5 RepliesSeems simple but users have no internet access. The application will be hosted internally on as Intranet site. The application will be able to make webservice calls to the internet. I tested and tried Mapquest. However all the other providers seems to assume the users are able to access the internet so their API's are javascript based with src tags pointing to internet URL's
View 4 RepliesFollowing the series of question, this is the code as of now has been developed and working fine. Now need to make some more tweek with this
1. Instead of distance from source to destination in KM can we have it in Miles
2. I need to show the distance between source and destinace only if destination falls under 25 mile radius from source else need to show the label message that no record found.

I used a Google Maps Distance Finder API that comes with two textboxes, one for the source, and one for the destination. It also comes with a button, that when clicked, will find the distance between the two locations using the funciton GetDistance(). The code before the function initializes the map. I created another button and used VB.Net to run SQL code first, and then to automatically populate the two textboxes, then I had it call the function GetDistance().
The issue I ran into is that the function won't calculate the distance, and the map never changes from its default state. I believe it's because it's not running the code that initializes the map. (I could be wrong) I have tried WebBrowser1, to call the click of the button, but I had to Inherit Forms, which I can't do, and I have also tried adding the top code into the GetDistance() function. Is it possible to call the initializing code before GetDistance()?

I just had to moved a site of mine from a hosting service here in the states to an offshore host located in Malaysia. My database is still located on the east coast of north america and I am wondering if the distance between the database and the file system might be to blame for slow load times or if moving my database as well would be a waste of time.

I'm going crazy and wasting a lot of time. I am running in DEBUG, checked the web.config to ensure debug=true is there, checked the code to ensure I am reaching it, cleared all temp files and pdb's. The only thing that works is to continually kill the solution, create a new solution and add all the projects again.I shouldn't have to do this every day.

View 1 RepliesI have followed this tutorial [URL] to get a google map displayed but now I want do the next step and read the long/lat and text out of my ADO.NET Entity Data Model and put it on the map (preferably the text should appear when clicking on the red spot in a white text box - as you know it from google). Has someone done this already and could let me know how I get the points on the google map? THis is how the function in my controller looks right now:
Function Map() As ActionResult
ViewData.Model = (From m In _db.ahn_mappoints Select m.LONG, m.LAT, BLOG = m.Text.Substring(0, 81) & "...").Take(2).ToList()
Return View()

I'm using asp.net AJAX and history points with the ScriptManager and it works great. My only problem is that when I make non AJAX pages I have come to love url-rewriting with nice "hackable" urls. Without SecureHistoryState my url will look like for example [URL] where "/Home/Frontpage" is the page to show. I have seen on other web-pages with AJAX (maybe not asp.net) that the url will change into for example [URL] which is a lot nicer. Or if I could have[URL]I would be very happy. I don't need the history url to contain anything else than the page path. Is this at all possible with asp.net AJAX?

I want/need to modify the mvcClientValidationMetadata before it is passed to the innards of the client-side validation machinery.What would be a good way to accomplish this (server-side or client-side, either way would be fine)?Can one somehow use a specialized FormContext (and override GetJsonValidationMetadata) or ViewContext - if so how? Or would it be better/easier to modify the mvcClientValidationMetadata on the client?
