• PHP reads 1.10 value as 1.1 (0 at end of variable not honored)

  - by adbox

  Hello, This is hard for me to word, but easier for me to demonstrate: I have a select option: <option <?php if($frequency[$key]=='1.10'){echo "selected";}?> value='1.10'>1 every 10 days</option> Really, $frequency[$key]=1.1; , but the above still shows up selected. I've never seen this before, and didnt know it could happen. Any ideas on how to prevent this? Working with php5. Thank you, Hudson

• Script to fix broken lines in a .txt file?

  - by Gravitas

  Hi, I'd love like to read books properly on my Kindle. To achieve my dream, I need a script to fix broken lines in a txt file. For example, if the txt file has this line: He watched Kahlan as she walked with her shoulders slumped down. ... then it should fix it by deleting the newline before the word "down": He watched Kahlan as she walked with her shoulders slumped down. So, fellow programmers, whats (a) the easiest way to do this and (b) the best language? p.s. The solution will involve searching for a lowercase letter in column 1, and deleting the newline before it to stitch the lines together. There are 1.2 million occurrences of this "rogue line break" in the novel I am trying to fix.

• What is an efficient way to erase substrings?

  - by Legend

  I have a long string and a set of <end-index, string> list like the following: long_sentence = "This is a long long long long sentence" indices = [[6, "is"], [8, "is a"], [18, "long"], [23, "long"]] An element 6, "is" indicates that 6 is the end index of the word "is" in the string. I want to get the following string in the end: >> print long_sentence This .... long ......... long sentence" I tried an approach like this: temp = long_sentence for i in indices: temp = temp[:int(i[0]) - len(i[1])] + '.'*(len(i[1])+1) + temp[i[0]+1:] While this seems to be working, it is taking exceptionally long time (more than 6 hours on 5000 strings inside a 300 MB file). Is there a way to speed this up?

• "Use windows xp style dpi scaling" disables automatic auto-hide of taskbar on W7. Workaround?

  - by Pelle

  We noticed that on W7 with DPI set to 125% or to 100% with ("Use windows xp style dpi scaling") turned off, our fullscreen mode (which sets the client rect of our window = desktop rect of the main monitor) no longer hides the task bar like it does for other settings. (The setting can be found in the Control Panel\Appearance and Personalization\Display section after clicking on the "Set custom text size (DPI)" link) I found the following interesting article: http://www.mathies.com/weblog/?p=908 So I set out to try to work around the bug in other means than manually hiding/restoring the taskbar visibility but so far I've failed and currently believe it's a bug in W7 (and possibly vista). The following applications also fail to work properly in fullscreen mode (the taskbar is still visible): * Microsoft Visual Studio 2008 * Microsoft Word 2007 * Adobe Reader 9.1.3 These apps work (probably by hiding the task bar through the WIN32 API): * Powerpoint Slide Show I also tried creating a brand new MFC-based app and use its "SetFullScreenMode()" functionality but it fails in the same way as all other apps on the list. Does anyone know of a workaround? Thanks, Per

• C++: Why does space always terminate a string when read?

  - by Nullw0rm

  Using type std::string to accept a sentence, for practise (I haven't worked with strings in C++ much) I'm checking if a character is a vowel or not. I got this: for(i = 0; i <= analyse.length(); i++) { if(analyse[i] == 'a' || analyse[i] == 'e' [..etc..]) { ...vowels++; } else { ... ...consenents++; } This works fine if the string is all one word, but the second I add a space (IE: aeio aatest) it will only count the first block and count the space as a consenent, and quit reading the sentence (exiting the for loop or something). Does a space count as no character == null? Or some oddity with std::string?, It would be helpful to know why that is happening!

Thanks

• C++: How would I get unix time?

  - by John D.

  I need a function or way to get the UNIX epoch in seconds, much like how I can in PHP using the time function. I can't find any method except the time() in ctime which seems to only output a formatted date, or the clock() function which has seconds but seems to always be a multiple of 1 million, nothing with any resolution. I wish to measure execution time in a program, I just wanted to calculate the diff between start and end; how would a C++ programmer do this? EDIT: time() and difftime only allow resolution by seconds, not ms or anything too btw.

• How to add model entity property in WCF RIA service

  - by Oblomingo

  I'm developing silverlight app with WCF Ria service. I'm using MS SQL database and Entity Framework as ORM framework (Database first method). Model with domain service are in separate project - App1.Data. Silverlight and generated model proxy classes are in App1 project. I want to add property to model entity class EntityClass to get this property on client side. So I did it that way - added this class to project App1.Data: public partial class EntityClass { [DataMember] public List<EntityClass2> PropertyName {get; set;} } After rebuilding EntityClass proxy on client side doesn't have this new property. Where is my mistake?

• XSLT Similar functionality to SQL "WHERE LIKE"

  - by Fishcake

  I have the following XML <Answer> <Label>FCVCMileage</Label> <Value>3258</Value> <Iteration>0</Iteration> <DataType>NUMBER</DataType> </Answer> And need to get the Value underneath the Mileage label. However the 4 letter prefix to Mileage could be any 1 of 8 different prefixes. I know I could find the value by testing for every combination using xsl:if or xsl:choose but is there a more elegant way that would work similar to the following SQL and also wouldn't need changes to code being made if other prefixes were added. WHERE label LIKE '%Mileage' NB. There will only ever be 1 label element containing the word Mileage Cheers!

• JPA in distributed Java EE configuration

  - by sof

  Hello, I'm developing a JEE application to run on Glassfish: Database (javaDB, MS SQL, MySQL or Oracle) EJB layer with JPA (Toplink essentials - from Glassfish) for database access JSF/Icefaces based web UI accessing the EJB layer The application will have a lot of concurrent web client, so I want to run it on different physical servers and use a load-balancer. My problem is now how to keep the applications synchronized. I intend to set up multiple servers, each running Glassfish with my EAR app installed. Whenever on one of the servers data is added to or removed from the database (via JPA, no direct SQL queries), this change should be reflected in the JPA layer on the other servers. I've been looking around for solutions to this, but couldn't find anything I really like (the full Toplink from Oracle claims to have a solution, but don't know). Doing a refresh before every access to a JPA entity could work, but is far from efficient. Are there any patterns, libraries, ... that could help here? Thanks a lot!

• Best means to store data locally when offline

  - by mickartz

  I am in the midst of writing a small program (more to experiment with vs 2010 than anything else) Despite being an experiment it has some practical use for our local athletics club. My thought was to access the DB (currently online) to download the current members and store locally on a laptop (this is a MS sql table, used to power the club's website). take the laptop to the event (yes there ARE places that don't have internet coverage), add members to that days race (also a row from a sql table (though no changes would be made to this), record results (new records in 3rd table) Once home, showered and within internet access again, upload/edit the tables as per the race results/member changes etc. So I was thinking i'd do something like write xml files locally with the data, including a field to indicate changes etc? If anyone can point me in a direction i would appreciate it...hell if anyone could tell me if this has a name, I'd appreciate it.

• Looking for examples of good IDEs to analyze for Form/Report design

  - by Paul Sasik

  I am working on a basic form/report designer. Some of the features i'm looking to implement are: Single or multiple selection of objects Alignment of objects (when several are selected) Same-sizing of objects (when several are selected) Moving/dragging of selected object(s) Selected object resizing in eight directions (using object grips) For features and look-and-feel I've analyzed and used a mixture of ideas from: MS Visual Studio 200x (most useful so far) Visio Crystal Reports My question is: Have I overlooked some other IDEs that provide these kinds of features that are better and user-friendlier examples of what to do than others i've looked at? (They don't have to be Microsoft products. That's just what i have ready access to.)

• Column.DbType affecting runtime behavior

  - by leppie

  Hi According to the MSDN docs, the DbType property/attribute of a Column type/element is only used for database creation. Yet, today, when trying to submit data to an IMAGE column on a SQLCE database (not sure if only on CE), I got an exception of 'Data truncated to 8000 bytes'. This was due to the DbType still being defined as VARBINARY(MAX) which SQLCE does not support. Changing the type to IMAGE in the DbType fixes the issue. So what other surprises does Linq2SQL attributes hold in store? Is this a bug or intended? Should I report it to MS? UPDATE After getting the answer from Guffa, I tested it, but it seems for NVARCHAR(10) adding a 11 char length string causes a SQL exception, and not Linq2SQL one. The data was truncated while converting from one data type to another. [ Name of function(if known) = ] A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll

• In Ruby on Rails Routing I Would Like to Use Dash `-` Instead of Underscore `_`

  - by pablitostar

  I would like all the URLs for my web applications to use dash - instead of underscore _ for word separators. I'm surprised about a couple of things really: Google et al. continue to distinguish them. That RoR doesn't have a simple global configuration parameter to map - to _ in the routing. Or does it? I found a few questions here and elsewhere, but the best solution I've seen is to use :as or a named route. That's quite annoying. So I'm thinking of modifying the Rails routing to check for that global config and change - to _ before dispatching to a controller action. But before I do that, I'm hoping someone can save me the trouble! Thanks in advance for any help, or even confirmation that my approach makes sense. I'd submit it back. BTW, I'm currently on 2.3.8, but hope to migrate to 3 soon.

• Calling this[int index] via reflection

  - by tkutter

  I try to implement a reflection-based late-bound library to Microsoft Office. The properties and methods of the Offce COM objects are called the following way: Type type = Type.GetTypeFromProgID("Word.Application"); object comObject = Activator.CreateInstance(type); type.InvokeMember(<METHOD NAME>, <BINDING FLAGS>, null, comObject, new object[] { <PARAMS>}); InvokeMember is the only possible way because Type.GetMethod / GetProperty works improperly with the COM objects. Methods and properties can be called using InvokeMember but now I have to solve the following problem: Method in the office-interop wrapper: Excel.Workbooks wb = excel.Workbooks; Excel.Workbook firstWb = wb[0]; respectively foreach(Excel.Workbook w in excel.Workbooks) // doSmth. How can I call the this[int index] operator of Excel.Workbooks via reflection?

• How to escape/strip special characters in the LaTeX document?

  - by Igor

  We implemented the online service where it is possible to generate PDF with predefined structure. User can choose a LaTeX template and then compile it with an appropriate inputs. The question we worry about is the security, that the malicious user was not able to gain shell access through the injection of special instruction into latex document. We need some workaround for this or at least a list of special characters that we should strip from the input data. Preferred language would be PHP, but any suggestions, constructions and links are very welcomed. PS. in few word we're looking form mysql_real_escape_string for LaTeX

• SQL Compact Edition database corruption

  - by jdv

  Hi, Our product is using MS SQL Compact Edition on a Windows machine (laptop). It's basically a metadata index for files we have on the filesystem. Recently we have seen databases getting corrupted. This happens when the machine is very busy moving files around and has to do a tiny bit of database changes at the same time. I was somewhat shocked that was at all possible. It was my expectation that the database would stay coherent whatever the circumstances. Of course we are doing something wrong. Things we have checked so far are: Use of only one db connection per thread specify the maximum size when opening the database The database is accessed only by one application, a .net based windows service. Are there other gotcha's?

• Convert a complicated string into an array in php

  - by Patrick Beardmore

  I have a php variable that comes from a form that needs tidying up. I hope you can help. The variable contains a list of items (possibly two or three word items with a space in between words). I want to convert it to a comma separated list with no superfluous white space. I want the divisions to fall only at commas, semi-colons or new-lines. Blank cannot be an item. Here's a comprehensive example (with a deliberately messy input): Variable In: "dog, cat ,car,tea pot,, ,,, ;;(++NEW LINE++)fly, cake" Variable Out "dog,cat,car,tea pot,fly,cake" Can anyone help?

• Tag Cloud Data Backend

  - by Waldron

  I want to be able to generate tag clouds from free text that comes from any number of different sources. For clarity, I'm not talking about how to display a tag cloud once the critical tags/phrases are already discovered, I'm hoping to be able to discover the meaningful phrases themselves... preferable on a PHP/MySQL stack. If I had to do this myself, I'd start by establishing some kind of index for words/phrases that gives a "normal" frequency for any word/phrase. eg "Constantinople" occurs once in every 1,000,000 words on average (normal frequency "0.000001"). Then as I analyze a body of text, I'd find the individual words/phrases (another challenge!), find frequencies of each within the input, and measure against the expected freqeuncy. Words that have the highest ratio against expected frequency get boosted priority in the cloud. I'd like to believe someone else has already done this, WAY better than I could hope to, but I'll be damned if I can find it. Any recommendations??

• Book resources for x86/x64 assembly programming on Win platform

  - by Scott Davies

  Hello, I ran a search for assembly language resources on stackoverflow.com and found some interesting results, but they seemed to boil down to two groups: 1) Assembly references to old ia32 architecture, such as the 80386 to Pentium 2) Windows agnostic books. Most of the commenters make the point that assembler is CPU dependent and that the OS is irrelevant, but it seems pointless to me to pick a book that has assembly examples that refer to MS-DOS interrupts and memory layouts. Likewise, learning assembler on Linux would seem to produce Linux executables Are there any: 1) Modern 2) x86/x64 3) on Windows platform - book resources available ? The reason I am targeting the Win platform is I would like to do low-level, OS internals programming, to supplement my Win C/C++ work. Thanks

• Does anyone actually use the phrase DHTML anymore?

  - by lafoaug

  I'm not sure if this is exactly appropriate but I have what I think is a interesting question. Does anyone actually use the phrase DHTML anymore in a professional environment? I came across the the word the other day for the first time in years and shuddered at the thought of it. To me the acronym Dynamic HTML just sounds so 1999, it brings me back to the days when I first discovered programming and web development and thought it was awesome to have scripts which modified the status bar and made things fly around the page. I for one have never used the phrase recently and would never dream of saying it in a professional environment to clients or colleges as I feel there is an amateur and dated stigma attached to it. What are your thoughts?
