Web Forms :: Order By With Closest Latitude And Longtitude?
Dec 27, 2010
I am working on Dating Site where i have to show most closest user's near to u on the basis of latitude and longtitude around the distance of 200 K.m.so what i am doing currently . i just find all the users latitude and longtitude and then convert them into the distance and then checkingwheather they are under the distance of 200 k.m . if out of 500 , 10 are under the 200 k.m distance they are displayed with No Issue :).As I am from london so the closest users should be from london as i myself frm london than other users which are under the boundry of 200 k.m.But it shows according to users id. not according to there closness to me The Coding that i did is show below.
string hold_latLong = "";

I have a model number in one table like 'Q4SD-X24K' and i have a model number in another table like 'q4%' and 'q4sa%d' and q4sd%' and each one contains different pdf links.
and if the user searches for 'Q4SD-X24K' , the closest match i.e q4sd will come and q4sd.pdf has to assign and show up .and i have written one stored proc and i am getting data in a datatable q4,q4sa%d,q4sd in asp.net. how can i match the closest one from this datatable to model number?
What I need: column display: users Rows display : months and days.
On clicking cell will open a popup
In popup we can : - select a status in a dropdownList, - if the status is "be close" => two calendars ( date start and end) - then apply a color for the selected period.
I know I would not find an exact need control, but I want a component that would be closest. Somethink like [URL]
I have 5 hard corded texboxes in a page in a sequence with sequence Number . Now i want to add re-order /re-arraning functionaly .. but i can't use ajax reorder list because i have 5 hard corded texbox. how can i maintain the order in Insert/Update cases. And also suggest me control that i can use, another than ajax re-order list. coz i not using any list items i have hard corded items on the page.
What i need is i need to bind last 10 Order in Gridview/details view with paging, and the same order detail also fetch from database and shown in another gridview.. if user click any oderNo in first Gridview/DetailView then i need to show Respective order detail in anther gridview..
without postback coz we already fetch 10 order with orderdetails from the database..and if user click next 10 orderNo using paging then again we need to load 10 orderNo with respective orderdeatils from database like this going on....as well as let me know how to take print of particular oder and order detail....?
The AjaxToolkit has a ReorderList. I'm searching for a jQuery solution that does the same and found this page. I would like to change the order of divs (vertically) and upload the new order to the database (ajax).
From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
I've been struggling for the past couple of days to get this right. I'm in the process of building something that takes a whole bunch of geographic points, builds a heat map from the data, then overlays it as a tile on Google Earth / Google Maps. A bit like this: [URL]
I have all the heatmap functionality nailed using random xy points. The last part is doing the actual conversion to convert my real lat/lng pairs into x/y pixels to be rendered onto the heatmap image. Lets say I the image is 500px x 500px. I know the min and max values for the lat/lng points, so technically I need to divide the spread between the pixels to get a pixel value for each degree based on the top left pixel of the image (0,0). I've been through so many examples, but I just cant get them to work. The last one I tried was this:
[Code]....
I feed data into my heatpoint function using these 2 functions above like this. Here's a set of 4 points:
[Code]....
The problem I get is that the result is the same for all the points - they all get plotted to exactly the same point. Now, the data is fairly localised, so I dont really need to take the curvature of the earth into consideration.
I have array of lattitude and longitude which is derived from one type of polygon, now i want to find all latitude and longitude from my database which are inside this polygon.So how can i achive this?
how can i raise event just after user change his position in google map using dragging map and get the latitude and longitude of center of google map and the miles its showing from center. i have got lots of pages on google related to it.. but not able to solve this.. please give me solution (i am using asp.net and javascript)
I want to get latitude and longitude from address in one of my asp.net application, i know it s possible using google apis but i want to do it without showing google map. How can i do that? I also want to get distance between two pairs of latitude and longitude.
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..
I 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
var txtlat=document.getElementById('TextBox1').value=GMap1.getCenter().lat(); var txtlong=document.getElementById('TextBox2').value=GMap1.getCenter().lng();
It gives a JavaScript error as "Object doesn't support this property or method". How can i do this?
i am developing a travel application. for that I need to calculate the future local datetime of a location using Datetime (a future date),longitude and latitude. (for Eg: i want to calculate the local datetime of a location on August-10- 2010 11.23 AM . Due to the day light saving time the datetime offset may change so i need to convert the august-10- 2010 11.23 AM to local time of the location) I have the inputs longitude, latitude and Date time. i can calculate the current local date using Longitude and latitude but cannot calculate accurately for *future date because of the day light saving time off set* . off set may varies on future dates. i am using asp.net and c# .
I cant seem to find a good example of how to build the query logic. We are allowing users to search based on lat/long and need to add radius as another parameter. So you enter 29.30125 as the latitude and -95.04590 as the longitude and pick say 15miles as the radius, i need to return all records that fall within that radius.. can someone suggest a good site to review this type of query?
I have latitudes and longitues in a table but they are in a nvarchar(50) field althought the values are like this -> 39.7355 I need to be able to convert those values to numeric to execute a calculation and update a new field
How to Track the Vehicles using Virtual earth control based on longitude and latitude.Every 5 seconds longitude and latitude values are coming from the database.based on these values vehicle position has to be changed. How to do it. Please give me complete code for this.
I have Postcode in my large database, which contains values like SL5 9JH, LU1 3TQ etc. Now when I am pasting above postcode to maps.google.com it's pointing to a perfect location.. My requirement is like I want to pass post codes to maps.google.com and it should return a related latitude and longitude of that pointed location, that I want to store in my database. So, most probably there should be some javascript for that If anybody have another idea regarding that please provide it
