• How to check if an apply-template filled variable is a string or (possibly) empty node in XSLT?

  - by calavera.info

  I need a test which would evaluate to true in two cases: There is a string inside which contains any non white space characters There is any node (which can be possibly empty) on a variable that is filled with apply-template call result. I tried test="normalize-space($var)" but this doesn't cover the empty tag possibility. I also tried simply this: test="$var" but this evaluate to true even for white space only strings. By the way "$var/*" produces an error "Expression ...something I don't remember... node-set" which is I think because of apply-template variable instantiation. Is there any (which means even multi level decision) solution for this? EDIT: I forgot to say that it's for XSLT 1.0 and preferably without any exslt extensions or similar.

• Flash CS4/AS3 Dynamic Text Box

  - by Jono

  Hi, I have created a XML image gallery, which displays text in between each slide. Now I have created a movie clip with a dynamic text field (with Render HTML selected) to display the text from the XML which is pushed into an array. Now, this all works great BUT... /n or /r is not creating a new line break (as they need to be custom). Yet if I create an Array and manually push strings "Bla bla bla /n bla bla bla" I get a line break. I have tried converting the Array item to string (even though it already is), I would also avoid creating textField = new textField() any Ideas would be welcomed. Cheers

• XDebug, how to disable remote debugging for single .php file?

  - by Kirzilla

  Hello, I'm using Eclipse IDE + remote Xdebug. EclipseIDE is listening 9000 port for some kind of Xdebug information. There are some php scripts running by cron on server. So, every cron execution xdebug is sending information to my workstation and EclipseIDE is trying to find this file in my project. But file couldn't be find because cron running scrits do not relate to the project I'm working with. So, every cron run Eclipse IDE is alerting this message http://img2.pict.com/22/fc/86/3299517/0/screenshot2b142.png I've tried to add to cron executed php scripts some strings... if (function_exists('xdebug_disable')) { xdebug_disable(); } ... but it didn't helped. Any ideas? Thank you

• C#/ASP.NET MVC 4 Instantiate Object Derived From Interface In Factory Method

  - by Chris

  Currently have a Factory class that features a GetSelector function, which returns a concrete implementation of ISelector. I have several different classes that implement ISelector and based on a setting I would like to receive the appropriate ISelector back. public interface ISelector { string GetValue(string Params); } public class XmlSelector : ISelector { public string GetValue(string Params) { // open XML file and get value } } public static class SelectorFactory { public static ISelector GetSelector() { return new XmlSelector(); // Needs changing to look at settings } } My question is what is the best way to store the setting? I am aware of using AppSettings etc. but I'm not sure whether I want to have to store strings in the web.config and perform a switch on it - just seems to be really tightly coupled in that if a new implementation of ISelector is made, then the Factory would need to be changed. Is there any way of perhaps storing an assembly name and instantiating based on that? Thanks, Chris

• MySQL DATETIME format comparison - is strtotime needed?

  - by Steffan

  I've been doing something along the lines of.. $dt1 = '1000-01-01 00:00:00'; //really some val from db $dt2 = '1000-01-01 00:00:10'; //another val maybe db maybe formatted if(strtotime($dt1) > strtotime($dt2){ //do something } Is the strtotime needed? can i do a more direct comparison on the datetime formatted strings? i.e. if($dt1 > $dt2){ //do something } Will that always work?

• PInvoke or using /clr:pure to compile

  - by Yin Zhu

  I have a set of numerical libraries in C++ and I want to call them interactively in a interpretive language like F# or IronPython. So I have two choices now: Compile the library in native DLL and use PInvoke to call functions in it. Compile the C++ library to .Net dll using visual c++ (/clr:pure compile option). The advantage of 1 is that it is very fast, however there are more work in it, e.g. I cannot PInvoke double pointer (e.g. float **), I must write another wrapper in the C++ library to make the interface friendly to .Net. The advantage of 2 is that I don't need to do know Mashaling strings, arrays, etc. However, the .net dll is slower compared to the native one. What others factors should be considered when choosing between the two?

• Dynamic Linq Library Help

  - by Alon

  Hi, I have the following class: public class Item { public Dictionary<string, string> Data { get; set; } } and a list of it: List<Item> items; I need to filter and order this list dynamicly using SQL-Like strings. The catch is, that I need to order it by the Data dictionary. For example: Order By Data["lastname"] or Where Data["Name"].StartsWith("a"). I thought to use the dynamic linq library, but is there any way that my clients can write without the Data[]? For example: Name.StartsWith("abc") instead of Data["Name"].StartsWith("abc") ? Thank you.

• NSMutableUrlRequest eats plus signs

  - by Mike

  I create NSMutableUrlRequest for sending data to server, add all necessary fields to it and then add the string for sending like this: [theRequest setHTTPBody:[postString dataUsingEncoding: NSUTF8StringEncoding]]; postString is a usual NSString. The problem is, when I receive this request at the server, all the plus (+) signs disappear from the http body. So if I had "abcde+fghj" on iPhone, I get "abcde fghj" on the server". Can this be some encoding problem from using dataUsingEncoding: NSUTF8StringEncoding? Or some NSMutableUrlRequest stripping feature? What can I do to make it stop stripping plus signs? I need to receive UTF8 strings at the server side.

• How to format a date as localized Short MonthDay string

  - by Wouter

  I would like to format a DateTime to a string containing the month name abbreviated and the date for use in axis labels in a graph. The default DateTime format strings do not contain abbreviated month. I guess there is no standard but I could take a substring of the first 3 characters of the month name and replace this into the MonthDay format. The reason I would use MonthDay is that the ordering of month and date is locale dependent. Does anyone have a better idea? http://msdn.microsoft.com/en-us/library/az4se3k1.aspx#MonthDay

• Retrieve a facebook page's type

  - by HectorMac

  I am trying to display a list of pages similar to the facebook search results. Along with the page's name, I would like to display the page type. The page's type property (from the Pages.getInfo API call returns the rather unfriendly looking strings from this list: http://wiki.developers.facebook.com/index.php/Page_Types Is there any way to map these to or retrieve the actual type descriptions facebook uses for page types in the facebook search results? These are not only more presentable, but appear to be less granular (both good things for my purpose).

• Is it possible to have "inherited partial structs" in c#?

  - by Balazs

  Is it possible to use partial structs to achieve something like this: Have an asp.net page base class with the following defined: public partial struct QuerystringKeys { public const string Username = "username"; public const string CurrentUser = "currentUser"; } Have an asp.net page, which inherits from the base class mentioned above, extend the partial declaration: public partial struct QuerystringKeys { /// <summary> /// The page number of the review instances list /// </summary> public const string Page = "page"; } The final goal is a QuerystringKeys struct with all three constant strings defined in it available to the asp.net page.

• Practical non-Turing-complete languages?

  - by Kyle Cronin

  Nearly all programming languages used are Turing Complete, and while this affords the language to represent any computable algorithm, it also comes with its own set of problems. Seeing as all the algorithms I write are intended to halt, I would like to be able to represent them in a language that guarantees they will halt. Regular expressions used for matching strings and finite state machines are used when lexing, but I'm wondering if there's a more general, broadly language that's not Turing complete? edit: I should clarify, by 'general purpose' I don't necessarily want to be able to write all halting algorithms in the language (I don't think that such a language would exist) but I suspect that there are common threads in halting proofs that can be generalized to produce a language in which all algorithms are guaranteed to halt. There's also another way to tackle this problem - eliminate the need for theoretically infinite memory. Once you limit the amount of memory the machine is allowed, the number of states the machine is in is finite and countable, and therefore you can determine if the algorithm will halt (by not allowing the machine to move into a state it's been in before).

• Reading string value from Excel with HSSF but it's double

  - by egaga

  Hi, I'm using HSSF-POI for reading excel data. The problem is I have values in a cell that look like a number but really are strings. If I look at the format cell in Excel, it says the type is "text". Still the HSSF Cell thinks it's numeric. How can I get the value as a string? If I try to use cell.getRichStringValue, I get exception; if cell.toString, it's not the exact same value as in Excel sheet. Thanks! edit: until this gets resolved, I'll use new BigDecimal(cell.getNumericCellValue()).toString()

• Converting a Doc object into a string in python

  - by Sam

  I'm using minidom to parse through an xml document. I took the data with yum tags and stored them in a list and calculated the frequency of the words. However, its not storing or reading them as strings in the list. Is there another way to do it? Right now this is what I have: yumNodes = [node for node in doc.getElementsByTagName("yum")] for node in yumNodes: yumlist.append(t.data for t in node.childNodes if t.nodeType == t.TEXT_NODE) for ob in yumlist: for o in ob: if word not in freqDict: freqDict[word] = 1 else: freqDict[word] += 1

• Reading and parsing email from Gmail using C#, C++ or Python

  - by jpnavarini

  I have to do a Windows application that from times to times access a Gmail account and checks if there is a new email. In case there is, it must read the email body and subject (a simple text email, without images or attachments). Please, do not use paid libs, and in case of any other libs used, give the download path. And I need the email body and subject only. So if the long and complex message that comes from Gmail could be parsed and only two strings containing the subject and the body, it would be perfect. Finally, I only have to get the new messages arrived since the last execution. So the read messages could be marked as "read" and only the new ones (marked as "new") are considered. The code can be written in Python or C++, but I prefer it in C#. Thank you for the help.

• How to parse the MailMessage object from raw email string

  - by Xmindz

  I have written a program in C# which connects to a POP Server and retrieves raw email message strings from the server using POP3 command RETR. Since the email message being retrieved by the program is in plain text format with all the headers and message body with in the same, its too difficult to extract each header and mail body from the raw string. Could anybody tell me a solution by which I can parse the entire raw text to a System.Net.Mail.MailMessage object? Following is a sample email raw string: +OK 1281 octets Return-Path: <[email protected]> Delivered-To: samplenet-sample:[email protected] X-Envelope-To: [email protected] Received: (qmail 53856 invoked from network); 22 Sep 2012 06:11:46 -0000 Received: from mailwash18.pair.com (66.39.2.18) MIME-Version: 1.0 From: "Deepu" <[email protected]> To: [email protected] Date: 22 Sep 2012 11:41:39 +0530 Subject: TEST Subject Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable Message-Id: <[email protected]> TEST Body .

• Integer comparison as string

  - by J Pollack

  Hi I have an integer column and I want to find numbers that start with specific digits. For example they do match if I look for '123': 1234567 123456 1234 They do not match: 23456 112345 0123445 Is the only way to handle the task by converting the Integers into Strings before doing string comparison? Also I am using Postgre regexp_replace(text, pattern, replacement) on numbers which is very slow and inefficient way doing it. The case is that I have large amount of data to handle this way and I am looking for the most economical way doing this.

• Microsoft Unity, parameters in constructor

  - by raffaeu

  I am using Unity with MVC and NHibernate. Unfortunately, our UnitOfWork resides in a different .dll and it doesn't have a default empty .ctor. This is what I do to register NHibernate: var connectionString = ConfigurationManager.ConnectionStrings["jobManagerConnection"].ConnectionString; var assemblyMap = ConfigurationManager.AppSettings["assemblyMap"]; container .RegisterType<IUnitOfWork, UnitOfWork>(new ContainerControlledLifetimeManager()); In my WebController I have this: /// <summary>Gets or sets UnitOfWork.</summary> [Dependency] public IUnitOfWork UnitOfWork { get; set; } The problem is that the constructor of UnitOfWork expects 2 mandatory strings. How I can setup the RegisterType for this Interface in order to pass the two parameters retreived from the web.config? Is it possible?

• varchar comparison in SQL Server

  - by Ram

  I am looking for some SQL varchar comparison function like C# string.compare (we can ignore case for now, should return zero when the character expression are same and a non zero expression when they are different) Basically I have some alphanumeric column in one table which needs to be verified in another table. I cannot do select A.col1 - B.col1 from (query) as "-" operator cannot be applied on character expressions I cannot cast my expression as int (and then do a difference/subtraction) as it fails select cast ('ASXT000R' as int) Conversion failed when converting varchar 'ASXT000R' to int Soundex would not do it as soundex is same for 2 similar strings Difference would not do it as select difference('abc','ABC') = 4 (as per msdn, difference is the difference in the soundex of 2 character expressions and difference =4 implies least different) Is there any other way of doing it ?

• Validation of user input or ?????????

  - by zaf

  We're letting users search a database from a single text input and I'm having difficulties in filtering some user supplied strings. For example, if the user submits: ????????? lcd SONY (Note the ?'s) I need to cancel the search. I include the base64 encoded version of the above string wrapped up so that its easy run: print(base64_decode("1MfLxc/RwdPHIGxjZCBTT05Z")); I've ignored such inputs before but now (am not sure why) just realised the mysql database query is taking nearly forever to execute so this is now on high priority. Another example to highlight that we are using utf-8 and mb_detect_encoding is not helping much: print(base64_decode("zqDOm8+Fzr3PhM63z4HOuc6/IM+Bzr/Phc+HzyU=")); ????t???? ?????% So: how can I detect/filter these inputs? how is this input being generated?

• Properties framework in java apps

  - by Roman

  Hi All I have been using spring for a while as my IOC. It has also a very nice way of injecting properties in your beans. Now I am participating in a new project where the IOC is Guice. I dont understand fully the concept how should I inject properties in to my beans using Guice. The question : Is it actually possible to inject raw properties ( strings , ints ) into my guice beans. If the answer is no , than maybe you know some nice Properties Framework for java. Because right now I wanted to use the ResourceBundle class for simple properties management in my app. But after using spring for a while this just dont seem seriously enought for me.

• NSString stringWithFormat

  - by Leo

  Hi Guys, I don't know what I am missing here. I am trying to concatenate strings using NSString stringWithFormat function. This is what I am doing. NSString *category = [row objectForKey:@"category"]; NSString *logonUser = [row objectForKey:@"username"]; user.text = [NSString stringWithFormat:@"In %@ by %@", category, logonUser]; The problem here is that it always print only one variable. Say if there is "Sports" in category and "Leo" in logonUser it will print "In Sports" and skip the remaining text. It should print "In Sports by Leo". Thanks

• Any way to get TStringList.CommaText to not escape commas with quotes?

  - by Mason Wheeler

  I'm doing some work with code generation, and one of the things I need to do is create a function call where one of the parameters is a function call, like so: result := Func1(x, y, Func2(a, b, c)); TStringList.CommaText is very useful for generating the parameter lists, but when I traverse the tree to build the outer function call, what I end up with looks like this: result := Func1(x, y, "Func2(a, b, c)"); It's quoting the third argument because it contains commas, and that produced invalid code. But I can't do something simplistic like StringReplace all double quotes with empty strings, because it's quite possible that a function argument could be a string with double quotes inside. Is there any way to make it just not escape the lines that contain commas?

• Using a UIPickerView to make a CoreData Relationship

  - by DVG

  Okay, so I have a fairly simple application set up. I have two different CoreData Entities, Games and Platforms, each have one attribute: name, and they have a one-to-many relationship between them. Platforms are populated on the first launch of the application, and will never change as a result of user input. I'm working on my Add view to let the user add new games to their personal database, and each game should select from a platform. The add view itself is a grouped table view with static custom cells. Tapping the platform cell should advance the user to another view to select the platform. My thought is that UIPickerView seems like a logical choice for the control, since the Platform list is static, but I'm not sure how to use it with CoreData. Even if I construct a fetch request to get the Platform objects and extract the strings out, how do I go about linking the new Game object to the original Platform object?

• DataAdapter Select string from base table schema?

  - by MattSlay

  When I built my .xsd, I had to choose the columns for each table, and it made a schema for the tables, right? So how can I get that Select string to use as a base Select command for new instances of dataadapters, and then just append a Where and OrderBy clause to it as needed? That would keep me from having to keep each DataAdapter's field list (for the same table) in synch with the schema of that table in the .xsd file. Isn't it common to have several DataAdapters that work on a certain table schema, but with different params in the Where and OrderBy clauses? Surely one does not have to maintain (or even redundently build) the field list part of the Select strings for half a dozen DataAdapters that all work off of the same table schema. I'm envisioning something like this pseudo code: BaseSelectString = MyTypedDataSet.JobsTable.GetSelectStringFromSchema() // Is there such a method or technique? WhereClause = " Where SomeField = @Param1 and SomeOtherField = @Param2" OrderByClause = " Order By Field1, Field2" SelectString=BaseSelectString + WhereClause + OrderByClause OleDbDataAdapter adapter = new OleDbDataAdapter(SelectString, MyConn)
