  • How can I figure out a users postal code if I have their latitude / longitude location? Need help w

    - by mike
    I'm using HTML5 geolocation to collect the users lat / long and I need to figure out what their postal code is as well. I have a database of all the lat / long for each postal code in the US & Canada. How can I write a query to find out what their postal code is? Below, is an example of how the data is structured in the 'zips' table. Country PostalCode Latitude Longitude USA 0051 40.813078 -73.046388 USA 00616 18.426456 -66.673779 I can't do a 'SELECT PostalCode FROM zips WHERE Latitude = user.lat AND Longitude = user.long'. I believe I need to find the nearest lat / long. Any suggestions on how I can write this?

  • Permutation on Rails Routes

    - by Kevin Sylvestre
    I currently have an application that for a set of parameters (location, category, budget, ...) a user can enter a "pretty" URL like: /location/canada/ontario /category/primary /budget/small Resulting in the respective parameters: params[:country] == 'canada' and params[:region] == 'ontario' params[:category] == 'primary' params[:budget] == 'small' I want to allow users to perform searches on multiple parameters at once (with each parameter optional). For example: /location/canada/ontario/category/primary/budget/small I understand that this can be achieved using URL parameters, but for SEO reasons I prefer to add the "pretty" parameters. Is this at all possible without listing all possible combination of routes (I have a large number of search-able fields)? I understand that route "globbing" maybe play a roll, but I am not sure how. Thanks.

  • Characters with jquery json

    - by Mikk
    Hi everyone, I'm using jquery $.getJSON to retrieve list of cities. Everything works fine, but I'm from Estonia (probably most of you don't know much about this country =D) and we are using some characters like õ, ü. ä, ö. When I pass letters like this to callback function, I keep getting empty strings. I've tried to base64 encode(server-side)-decode(jquery base64 plugin) strings (i thought it was a good idea as long as I can compress pages with php, so I don't have to worry about bandwidth), but in this way I end up with some random chinese symbols. What would be the best workaround for this problem. Thank you.

  • DB2 Select - Replace STATES with two character code

    - by user2528724
    I have a Users Table where it stores city, state and country along with other Users attributes. The states are stored as California, Alabama and so forth. Now I want to retrieve the user information for certain records but the state should get translated to two digit code. Say 'California' should be 'CA'. How should I go about doing this. I was thinking to create a mapping table for state names with there abbreviation and then use some sort of replace function to do it. Any ideas ?

  • Using Linq on a Dataset

    - by JasonMHirst
    Can someone enlighthen me with regards to Linq please? I have a dataset that is populated via a SQL Stored Procedure, the format of which is below: Country | Brand | Variant | 2004 | 2005 | 2006 | 2007 | 2008 The number of rows varies between 50 and several thousand. What I'm trying to do is use Linq to interrogate the dataset (there will be several Linq queries based on user options), but a simple example would be to SUM the year columns based on Brand. I have the following that I believe creates a template for me to work with: But from here on I'm absolutely stuck! sqlDA.Fill(ds, "Profiler") Dim brandsQuery = From cust In ds.Tables(0).AsEnumerable() Select _BrandName = cust.Item("BrandName"), _y0 = cust.Item("1999"), _y1 = cust.Item("2004"), _y2 = cust.Item("2005"), _y3 = cust.Item("2006"), _y4 = cust.Item("2007"), _y5 = cust.Item("2008") I'm tried to look at examples, but can't see any that are VB.Net based and/or show me how to Sum/Group. Can someone please provide an example so I can perhaps learn from it. Thanks.

  • Drupal - Views + node preview woes

    - by Ace
    Hey there! I have a few Views on my Drupal 6 site which take care of some of a node's fields. For example, I have a content type called Country, which has a field called Capital. I've excluded this field in the node display, but there is a view that takes the node ID as an argument and displays it in the right column. This is all very pretty and has been working out well for me, but how do I take care of the node preview mode? Since the node isn't saved yet, the Capital field won't have its new value yet. Note: I am ready to do some very dirty hacks to make this work :)

  • Refresh combo box in Windows Form VB.NET

    - by fireBand
    Following is the code to populate combobox using DataSource Dim CountryList As Array = MyCtrl.GetAllCountries With cbCountyList .DataSource = CountryList .DisplayMember = "CountryName" .ValueMember = "CountryID" End With After adding a new COuntry Name to Database I want to reflect the changes in combobox. Repeating this code is not an option becasue it triggers SelectIndexChange event and had to do some crappy work around to avoid that. So I was wondering if there is way to refresh the combobox list. I actually thought binding with the DataSource property supposed to do it automatically. I also tried cbCountyList.Refresh() Thanks in advance.

  • Java Custom exception throw behaves differently between different Projects

    - by Pablo
    I am attempting to call the following in my code: public void checkParticleLightRestriction(Particle parent) throws LightException { if ( parent == null ) { throw new LightException("quantum-particle-restrict.23", this); } In one Project the exception is thrown and the effect is similar to calling "return" whereby I am returned back to the point immediately succeeding where this method was called. However in another Project I get thrown completed out of the current package and to a point way prior to the point preceeding this method. It likes instead of being kicked out of a bar I am being deported all the way out of the country. My option are the wrap the throw in a try / catch but I am wondering why this difference in behaviour beween the 2 projects ?

  • Indexed key vs indexed separate columns, which one is faster ?

    - by Jerry
    In MYSQL, from a pure performance perspective, if I have a table with large amount of data with 10/1 read/write ratio. is it faster in read/write performance to have 4 search criteria in separate columns and all indexed or have them combined in to one single string acting as a key and store in one indexed column ? e.g. say this table with 5 columns, first name, last name, sex, country and file where the first four columns will ALWAYS be given as a part of search parameters in a search or have a table with two columns, key and file. where the value of key can be john-smith-male-australia ?? I don't quite get the pros and cons. the point I try to stress is the fact that all parameters will be given.in a search.

  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.
