• RESTful Question/Answer design?

  - by Kirschstein

  This is a toy project I'm working on at the moment. My app contains questions with multiple choice answers. The question url is in the following format, with GET & POST mapping to different actions on the questions controller. GET: url.com/questions/:category/:difficulty => 'ask' POST: url.com/questions/:category/:difficulty => 'answer' I'm wondering if it's worth redesigning this into a RESTful style. I know I'd need to introduce answers as a resource, but I'm struggling to think of a url that would look natural for answering that question. Would a redesign be worthwhile? How would you go about structuring the urls?

• Line of code doesnt follow sequential execution

  - by ryudice

  Hi, I'm having a problem with a code that doesnt follow sequential execution although I'm not using threading. My code calls one function and when I'm debugging inside the function, it returns to the line of code following the function call although the function hasnt finished executing, I have no idea why this would happen, any ideas? thanks in advance. workflow.SaveControlTiempo(solEntity, traId, Usuario.GetUsrId());// this is my function RadAjaxManager.GetCurrent(Page).RadAlert("Solicitud Transicionada con \u00c9xito"); // code execution continues here even if the function hasnt finished and since the function hasnt finished I get an exception var javascripFunction = "CloseWindow('Solicitud <b>{0}</b><br />Transicionada con \u00c9xito.<li> <b>Etapa Destino: </b>{1}<li><b>Usuario: </b>{2}');"; javascripFunction = string.Format(javascripFunction, solEntity.SOL_CODIGO, solEntity.WKF_ETP_ETAPAS.ETP_DES, DNNUtil.GetInstance().GetUserName(solEntity.USR_ID));

• Convert BLOB to Jpg using C#

  - by TGuimond

  Hello, I am currently developing a web application that receives data from an on-site oracle database. The database developers have developed some web-services that I am able to call and send/receive data to and from the the database. When I want to display an image the method returns the image in BLOB format. My question is: what is the best way to convert BLOB to .jpg or .bmp so I can display the image correctly? If someone could point me in the right direction that would be great! Cheers, Tristan

• smaller date regex

  - by Jeremy

  I have a regex used to validate dates: ^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$ Works really well, but I am using it all over the place with asp.net regex validators and I want to minimize it so I can reduce page size. It works with dd/mm/yyyy format and handles leap years. I'm looking for a more concise regex statement.

• database security with php page that spits out XML

  - by Rees

  Hello, I just created a PHP page that spits outs some data from my database in an XML format. This data is fetched from a flex application I made. I had spent a long time formatting my tables and database information and do not want anyone to be able to simply type www.mysite.com/page_that_spits_out_XML.php and steal my data. However, at the same time I need to be able to access this page from my flex application. Is there a way I can prevent other people from doing this? Thank you!

• Reading a Windows 'binary' float into a ASP jscript variable

  - by user89691

  I need to read files produced by a legacy Windows app that stores real numbers (the 8-byte "double" type) in binary - i.e. as a packed array of 8 bytes. I can read the 8 byte group OK but how can I present it to my ASP JScript code such I can get the real number back again. Or to put it another way: Say a file was produced by a Windows (Delphi) program: Assign (f, 'test.bin') ; rewrite (f, 1) ; r := 1234.56E78 ; BlockWrite (f, r, SizeOf (Double)) ; Close (f) ; Inspection of the file will show it contains 8 bytes, being: 94 0E 4C CA C2 97 AD 53 which is the real number in IEEE format. Assuming I can read these 8 bytes back in ASP, is there a simple way of getting the real number back again?

• Difference between dates

  - by Ben C

  I want to calculate the difference between two times, one of which is the current time, and the other is just in the format HH:MM, always in the future. If I just subtract $futuretime from $now, it should, of course, be a positive number. This works fine until... If $now is in the afternoon or evening and $futuretime is, say, 7AM next morning, how can I force it to understand the the time is always going to be in the future? (It's for working out the time of something that occurs about every half an hour during working hours, and then stops until the following morning) Thanks in advance!

• Saving CSV in cocoa

  - by happyCoding25

  Hello, I need to make a cvs file in cocoa. To see how to set it up I created one in Numbers and opened it with text edit it looked like this: Results,,,,,,,,,,,, ,,,,,,,,,,,, A,10,,,,,,,,,,, B,10,,,,,,,,,,, C,10,,,,,,,,,,, D,10,,,,,,,,,,, E,10,,,,,,,,,,, So to replicate this in cocoa I used: NSString *CVSData = [NSString stringWithFormat:@"Results\n,,,,,,,,,,,,\nA,%@,,,,,,,,,,,\nB,%@,,,,,,,,,,,\nC,%@,,,,,,,,,,,\nD,%@,,,,,,,,,,,\nE,%@,,,,,,,,,,,",[dataA stringValue], [dataB stringValue], [dataC stringValue], [dataD stringValue], [dataE stringValue]]; Then [CVSData writeToFile:[savePanel filename] atomically:YES]; But when I try to open the saved file with Numbers I get the error “Untitled.cvs” could not be handled because Numbers cannot open files in the “Numbers Document” format. Could this be something with the way cocoa is encoding the file? Thanks for any help

• Mathematica - Import CSV and process columns?

  - by Casey

  I have a CSV file that is formatted like: 0.0023709,8.5752e-007,4.847e-008 and I would like to import it into Mathematica and then have each column separated into a list so I can do some math on the selected column. I know I can import the data with: Import["data.csv"] then I can separate the columns with this: StringSplit[data[[1, 1]], ","] which gives: {"0.0023709", "8.5752e-007", "4.847e-008"} The problem now is that I don't know how to get the data into individual lists and also Mathematica does not accept scientific notation in the form 8.5e-007. Any help in how to break the data into columns and format the scientific notation would be great. Thanks in advance.

• Syntax highlighting in MS Word document

  - by ArunSaha

  I want to insert some C/C++ source code into a Microsoft Word document. I have no problem in copying the code from source file and pasting into Word. I can do fixed-width. But, in Word, I see the code in black-and-white format; I loose the syntax highlighting as I get in the source code editor (for me, gvim). So, my question is, is there any way to do syntax highlighting of C/C++ source code in MS Word?

• How is joystick axis information formatted from a USB Joystick?

  - by aquanar

  I actually just have a rather small question, but I have had the HARDEST time finding information about it. For the application I am programming for, there will be a 3-axis joystick being connected via USB to a Windows XP computer, and it is being handled by directx. That information will then be sent elsewhere to an embedded controller. I don't need to know too much of the intricacies of how directx handles it, but I want to know, how is the data for the axes formatted? Nearest I can tell, most joysticks nowadays have 12 bits of resolution, so is the data output as a 12-bit 2's compliment number? And after that, is it represented as a signed 16-bit integer when it is captured from directx? I'd like to know this so I know how I will work with the data at the embedded platform side, such as how to format the packets sending data to the embedded side, as well ashow to use the information once it is on the embedded side.

• My Android 2.1 Nexus One, rooted and unlocked and unplugged and unchained! Unfreakinbelievable!

  - by misbell

  So anyway. i fastbooted and superrooted, and all's fine in the merry old land of Oz. So yeah, now I can see /data/data.. in DDMS, both the plugin and the tool, which is great. but when I attach my phone, I still can't see the main drive. All I can see is the SD card. Using OSX, so when I use Disk Utility, I can see the machine then see the SD Card. is the problem that none of the tools I am using, except DDMS and ADB shell, know how to read that main Android drive? It's the same format as the qemu img, right? Someone HAS to come up with a tool that can do this, let me hack my phone and access the main drive via my USB connector, and mount that drive on my native file system. It just can NOT be that hard. Err, can it? All smiles! Michael

• 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()

• Rails paperclip problem

  - by palani

  I have uploaded the video into my rails application by using thoughtbot-paperclip then the video is converted into "flv" format by using ffmpeg. For your reference here I specified some of my model sample code: model.rb: has_attached_file :source,:styles => {:thumb => "137x85>" } If i specified :url or :path option it doesn't worked correctly. In my view I played my video by using the following line: <%= @model.source.url.gsub(/\?.*/,'')%> If i use <%= @model.source.url%>, the video is not played. When do the puts for video url it shows me the video URL as /source/original/sample/sample.fly?22000009. I knew that the last portion is a timestamp, but i want to use <%= @model.source.url%>. What's my mistake here can any one correct me please?

• Zend Framework - POP3 - retrieving message source

  - by pako

  Is it possible to retrieve the complete message source (similar tu Unix Mbox format) using Zend_Mail_Storage_Pop3 from the Zend Framework? I'm using the following code to retrieve messages: $mail = new Zend_Mail_Storage_Pop3(array('host' => 'localhost', 'user' => 'test', 'password' => 'test')); echo $mail->countMessages() . " messages found\n"; foreach ($mail as $message) { echo "Mail from '{$message->from}': {$message->subject}\n"; } It looks like the $mail object contains the message already split up into fields (ie. headers, contents, etc.). Is there any way to retrieve the original message source? I would like to be able to store it so if I need to parse the message again using a different tool, I will have the necessary information.

• How to get a non-XML output using JDOM XSLTransformer?

  - by Neil McF

  Hello, I have an XML file which I'd like to parse into a non-XML (text) file based on a XLST file. The code in both seem correct, and it works when testing manually, but I'm having a problem doing this programatically. I'm using JDOM's XSLTransformer class to apply the XSLT to the XML and it returns it in the format of a JDOM Document. The problem here is that I can't seem to access anything in the Document as it is not a proper XML file and I get a "java.lang.IllegalStateException: Root element not set" error. Is there a better way within Java to obtain a non-XML file as a result of XSLT?

• SSMS Results to Grid - CRLF not preserved in copy/paste - any better techniques?

  - by Cade Roux

  When I have a result set in the grid like: SELECT 'line 1 line 2 line 3' or SELECT 'line 1' + CHAR(13) + CHAR(10) + 'line 2' + CHAR(13) + CHAR(10) + 'line 3' With embedded CRLF, the display in the grid appears to replace them with spaces (I guess so that they will display all the data). The problem is that if I am code-generating a script, I cannot simply cut and paste this. I have to convert the code to open a cursor and print the relevant columns so that I can copy and paste them from the text results. Is there any simpler workaround to preserve the CRLF in a copy/paste operation from the results grid? The reason that the grid is helpful is that I am currently generating a number of scripts for the same object in different columns - a bcp out in one column, an xml format file in another, a table create script in another, etc...

• Capture and display console output at the same time

  - by Patrick

  Hi, MSDN states that it is possible in .NET to capture the output of a process and display it in the console window at the same time. Normally when you set StartInfo.RedirectStandardOutput = true; the console window stays blank. As the MSDN site doesn't provide a sample for this I was wondering if anyone would have a sample or could point me to a sample? When a Process writes text to its standard stream, that text is normally displayed on the console. By redirecting the StandardOutput stream, you can manipulate or suppress the output of a process. For example, you can filter the text, format it differently, or write the output to both the console and a designated log file. MSDN This post is similar to http://stackoverflow.com/questions/786726/capture-standard-output-and-still-display-it-in-the-console-window by the way. But that post didn't end up with a working sample. Thanks a lot, Patrick

• Steaming a non-PCM WAV file to a SilverLight application

  - by Satumba

  Hi, I would like to allow users to play recorded WAV files that stored on a server back to a Silverlight application as a client to play them. I saw that there is a way to play a WAV file on Silverlight (here), but when i tried to impliment it, i got an error playing the file because it is not in PCM format but encoded. The files that i'm trying to play are encoded with a special encoder, so i thought that the only way is to decode the WAV file on the server and stream it back to the client. The limitation is that the decode process should occur in real time because it is not reasonable to convert all the WAV files that exists. Is it possible to do it? Which streamer can i use? (Windows Media Service can help here?) Does somebody has any experience with such a scenario? Appreciate your help.
