• Validating alphabetic only string in javascript

  - by Click Upvote

  How can I quickly validate if a string is alphabetic only, e.g var str = "!"; alert(isLetter(str)); // false var str = "a"; alert(isLetter(str)); // true Edit : I would like to add parenthesis i.e () to an exception, so var str = "("; or var str = ")"; should also return true.

• Loop through array, print with string.

  - by Adam

  I have a simple array like: var myArr=["one","two","three"]; an I have a counting loop, which increases the value of var i by one. What I want to do is print the next value from the array each time the loop runs, next to a text string, like so: alert('value number '+myArr[i]+); But for some reason I can't get this to work. The following code works, so I'm assuming I'm not calling the counter right: alert('value number '+myArr[0]+);

• Best way to create IPEndpoint from string

  - by S_Hultqvist

  Since IPEndpoint contains a ToString method that outputs: 10.10.10.10:1010 There should be a Parse & TryParse method but there isn't. I can split the string on the ':' and parse a IP address and a port. But is there a more elegant way?

• When I do ""+1 I get a String - Why

  - by steve

  Hi, Please understand firstly that I fully understand that Java will return a String when I use ""+int. What I'm really not sure about is what exactly is happening down at the memory aspect. How exactly is java performing this conversion. I mean this in a very indepth way, not 'auto boxing' or anything like that :) I'm hoping someone with a deeper understanding can explain what exactly is done.

• XML parsing error: 'A string literal was expected' when inserting values into table

  - by Christian

  In Microsoft Sequel Server 2008 I am attempting to insert values into an sql table with the columns type_id of datatype int and xml_info of datatype XML. I am using the following query: INSERT INTO tbl_applied_devices ([type_id],[xml_info]) VALUES (1,'<Profile ID=99><Server><ID>BC4A18CA-AFB5-4268-BDA9-C990DAFE7783</ID> <Name>localhost</Name><Services></Services></Server></Profile>') But I keep getting this error: Msg 9413, Level 16, State 1, Line 4 XML parsing: line 1, character 13, A string literal was expected What am I doing incorrectly? Thank you for the help. EDIT: I found that the source of the error is the xml element's ID attribute, where seems to be what is causing the error. How can I correctly insert xml with an attribute ? Do I need to somehow escape one of the characters?

• Use LINQ to query nested OData collection

  - by Kyle Russell

  I'm playing around with the new Netflix OData feed (http://odata.netflix.com/Catalog/) and having some issues. I'm trying to learn LINQ at the same time but having difficulty doing what I thought was going to be quite simple. I'd like to return a list of Titles that match a given Genre. The Titles object contains a collection of Genres. I'm not sure how to write this query. My attempt below does not appear to work using LINQPad. from t in Titles where t.Genres.Name.Contains("ABC") select t

• How to query flags stored as enum in NHibernate

  - by SztupY

  How to do either a HQL or a Criteria search (the latter is preferred) involving an enum that is used as flags. In other words, I have a persisted enum property that stores some kind of flags. I want to query all the records that have one of these flags set. Using Eq won't work of course because that will only be true, if that is the only flag set. Solving this using the Criteria API would be the best, but if this is only doable using HQL that is good too.

In settings.py I have SITE_ID = 2 line. Still, in this call: return Site.objects.get(pk=site_pk) in traceback, site_pk=1. How can I fix this?

• Strange error occurring when using wcf to run query against sql server

  - by vondip

  Hi all, I am building an asp.net application, using II6 on windows server 2003 (vps hosting). I am confronted with an error I didn't receive on my development machine (windows 7, iis 7.5, 64 bit). When my wcf service tries launching my query running against a local sql server this is the error I receive: Memory gates checking failed because the free memory (43732992 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element. and ideas??

  Here is a silly question. Lets say I have a query that produces for a list box, and it produces values for three stores Store A 18 Store B 32 Store C 54 Now if I ORDER BY in the sql statement the only thing it will do is descending or ascending alphabetically but I want a certain order (only because THEY WANT A CERTAIN ORDER) .....so is there a way for me to add something to the SQL to get Store B Store C Store A i.e. basically row by row what i want. thanks!

• MySQL query performance - 100Mb ethernet vs 1Gb ethernet

  - by Rob Penridge

  Hi All I've just started a new job and noticed that the analysts computers are connected to the network at 100Mbps. The queries we run against the MySQL server can easily be 500MB+ and it seems at times when the servers are under high load the DBAs kill low priority jobs as they are taking too long to run. My question is this... How much of this server time is spent executing the request, and how much time is spent returning the data to the client? Could the query speeds be improved by upgrading the network connections to 1Gbps? Thanks Rob
