• Special characters from MySQL database (e.g. curly apostrophes) are mangling my XML

  - by Toph

  I have a MySQL database of newspaper articles. There's a volume table, an issue table, and an article table. I have a PHP file that generates a property list that is then pulled in and read by an iPhone app. The plist holds each article as a dictionary inside each issue, and each issue as a dictionary inside each volume. The plist doesn't actually hold the whole article -- just a title and URL. Some article titles contain special characters, like curly apostrophes. Looking at the generated XML plist, whenever it hits a special character, it unpredictably gobbles up a whole bunch of text, leaving the XML mangled and unreadable. (...in Chrome, anyway, and I'm guessing on the iPhone. Firefox actually handles it pretty well, showing a white ? in a black diamond in place of any special characters and not gobbling anything.) Example well-formed plist snippet: <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Rows</key> <array> <dict> <key>Title</key> <string>Vol. 133 (2003-2004)</string> <key>Children</key> <array> <dict> <key>Title</key> <string>No. 18 (Apr 2, 2004)</string> <key>Children</key> <array> <dict> <key>Title</key> <string>Basketball concludes historic season</string> <key>URL</key> <string>http://orient.bowdoin.edu/orient/article_iphone.php?date=2004-04-02&amp;section=1&amp;id=1</string> </dict> <!-- ... --> </array> </dict> </array> </dict> </array> </dict> </plist> Example of what happens when it hits a curly apostrophe: This is from Chrome. This time it ate 5,998 characters, by MS Word's count, skipping down to midway through the opening the title of a pizza story; if I reload it'll behave differently, eating some other amount. The proper title is: Singer-songwriter Farrell ’05 finds success beyond the bubble <dict> <key>Title</key> <string>Singer-songwriter Farrell ing>Students embrace free pizza, College objects to solicitation</string> <key>URL</key> <string>http://orient.bowdoin.edu/orient/article_iphone.php?date=2009-09-18&amp;section=1&amp;id=9</string> </dict> In MySQL that title is stored as (in binary): 53 69 6E 67 |65 72 2D 73 |6F 6E 67 77 |72 69 74 65 72 20 46 61 |72 72 65 6C |6C 20 C2 92 |30 35 20 66 69 6E 64 73 |20 73 75 63 |63 65 73 73 |20 62 65 79 6F 6E 64 20 |74 68 65 20 |62 75 62 62 |6C Any ideas how I can encode/decode things properly? If not, any idea how I can get around the problem some other way? I don't have a clue what I'm talking about, haha; let me know if there's any way I can help you help me. :) And many thanks!

• jQuery UI + Gmaps = Problems (for me at least) HELP!!

  - by Luis

  Hi there! I started using jQuery as soon as I found out about it, it is very powerfull but I started struggling when I tried to load Gmaps api into the tabs jQuery UI brings. Strangly enough in IE 6,7,8 it works fine, but in Firefox, Safari (I'm using mac but tested it in windows and they both give the same problems) the map doesn't load entirely. When I click on the tab where the map loads in, only part of the map is fully operational, the rest is grey and not clickable. Please take a look at the link below and click the third tab in firefox/safari and IE and you will see the problem. http://movewithusoverseas.com/index-new.php?z=product-info.html&pid=1 I don't know if it is a bug in the jQuery UI code or I'm doing something wrong. If I load the map out of the tabs the map is shown OK. I'm fighting with this problem for a week and a half... any help will be much appreciated. Thanks in advance. Luis

  Hello All, I stuck in middle of this situation,Please help me out. My question is that I want to send files (Total 11 PDF Files) to android app using web service. I tried it with below code.Main Class from which web service is created public class MultipleFilesImpl implements MultipleFiles { public FileData[] sendPDFs() { FileData fileData = null; // List<FileData> filesDetails = new ArrayList<FileData>(); File fileFolder = new File( "C:/eclipse/workspace/AIPWebService/src/pdfs/"); // File fileTwo = new File( // "C:/eclipse/workspace/AIPWebService/src/simple.pdf"); File sendFiles[] = fileFolder.listFiles(); // sendFiles[0] = fileOne; // sendFiles[1] = fileTwo; DataHandler handler = null; char[] readLine = null; byte[] data = null; int offset = 0; int numRead = 0; InputStream stream = null; FileOutputStream outputStream = null; FileData[] filesData = null; try { System.out.println("Web Service Called Successfully"); for (int i = 0; i < sendFiles.length; i++) { handler = new DataHandler(new FileDataSource(sendFiles[i])); fileData = new FileData(); data = new byte[(int) sendFiles[i].length()]; stream = handler.getInputStream(); while (offset < data.length && (numRead = stream.read(data, offset, data.length - offset)) >= 0) { offset += numRead; } readLine = Base64Coder.encode(data); offset = 0; numRead = 0; System.out.println("'Reading File............................"); System.out.println("\n"); System.out.println(readLine); System.out.println("Data Reading Successful"); fileData.setFileName(sendFiles[i].getName()); fileData.setFileData(String.valueOf(readLine)); readLine = null; System.out.println("Data from bean " + fileData.getFileData()); outputStream = new FileOutputStream("D:/" + sendFiles[i].getName()); outputStream.write(Base64Coder.decode(fileData.getFileData())); outputStream.flush(); outputStream.close(); stream.close(); // FileData fileDetails = new FileData(); // fileDetails = fileData; // filesDetails.add(fileData); filesData = new FileData[(int) sendFiles[i].length()]; } // return fileData; } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } return filesData; } } Also The Interface MultipleFiles:- public interface MultipleFiles extends Remote { public FileData[] sendPDFs() throws FileNotFoundException, IOException, Exception; } Here I am sending an array of bean "File Data",having properties viz.

• msys+mingw - is there installer or at least .tar.lzma/.zip?

  - by Maciej Piechotka

  I try to install n'th time the msys+mingw - however with little success. I need the minimal developer system (standard tools such as sed/awk+autotools+gcc) however each time something is not working (for example currently when I try to run autotools m4 goes into some error loop on AC_INIT). I know they stopped providing installer 'for easy update of components' and they are working on something but maybe there is something unofficial.

• World's Most Challening MySQL SQL Query (least I think so...)

  - by keruilin

  Whoever answers this question can claim credit for solving the world's most challenging SQL query, according to yours truly. Working with 3 tables: users, badges, awards. Relationships: user has many awards; award belongs to user; badge has many awards; award belongs to badge. So badge_id and user_id are foreign keys in the awards table. The business logic at work here is that every time a user wins a badge, he/she receives it as an award. A user can be awarded the same badge multiple times. Each badge is assigned a designated point value (point_value is a field in the badges table). For example, BadgeA can be worth 500 Points, BadgeB 1000 Points, and so on. As further example, let's say UserX won BadgeA 10 times and BadgeB 5 times. BadgeA being worth 500 Points, and BadgeB being worth 1000 Points, UserX has accumulated a total of 10,000 Points ((10 x 500) + (5 x 1000)). The end game here is to return a list of top 50 users who have accumulated the most badge points. Can you do it?

• Should I be regularly shrinking my DB or at least my log file?

  - by Tom

  My question is, should I be running one or both of the shrink command regularly, DBCC SHRINKDATABASE OR DBCC SHRINKFILE ============================= background Sql Server: Database is 200 gigs, logs are 150 gigs. running this command SELECT name ,size/128.0 - CAST(FILEPROPERTY(name, 'SpaceUsed') AS int) / 128.0 AS AvailableSpaceInMB FROM sys.database_files;` produces this output.. MyDB: 159.812500 MB free MyDB_Log: 149476.390625 MB free So it seems there is some free space. We backup transaction logs every hour, diff backup 5 nights a week, full backup the other 2 nights of the week.

• How to obtain the first cluster of the directory's data in FAT using C# (or at least C++) and Win32A

  - by DarkWalker

  So I have a FAT drive, lets say H: and a directory 'work' (full path 'H:\work'). I need to get the NUMBER of the first cluster of that directory. The number of the first cluster is 2-bytes value, that is stored in the 26th and 27th bytes of the folder enty (wich is 32 bytes). Lets say I am doing it with file, NOT a directory. I can use code like this: static public string GetDirectoryPtr(string dir) { IntPtr ptr = CreateFile(@"H:\Work\dover.docx", GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, IntPtr.Zero, OPEN_EXISTING, 0,//FILE_FLAG_BACKUP_SEMANTICS, IntPtr.Zero); try { const uint bytesToRead = 2; byte[] readbuffer = new byte[bytesToRead]; if (ptr.ToInt32() == -1) return String.Format("Error: cannot open direcotory {0}", dir); if (SetFilePointer(ptr, 26, 0, 0) == -1) return String.Format("Error: unable to set file pointer on file {0}", ptr); uint read = 0; // real count of read bytes if (!ReadFile(ptr, readbuffer, bytesToRead, out read, 0)) return String.Format("cant read from file {0}. Error #{1}", ptr, Marshal.GetLastWin32Error()); int result = readbuffer[0] + 16 * 16 * readbuffer[1]; return result.ToString();//ASCIIEncoding.ASCII.GetString(readbuffer); } finally { CloseHandle(ptr); } } And it will return some number, like 19 (quite real to me, this is the only file on the disk). But I DONT need a file, I need a folder. So I am puttin FILE_FLAG_BACKUP_SEMANTICS param for CreateFile call... and dont know what to do next =) msdn is very clear on this issue http://msdn.microsoft.com/en-us/library/aa365258(v=VS.85).aspx It sounds to me like: "There is no way you can get a number of the folder's first cluster". The most desperate thing is that my tutor said smth like "You are going to obtain this or you wont pass this course". The true reason why he is so sure this is possible is because for 10 years (or may be more) he recieved the folder's first cluster number as a HASH of the folder's addres (and I was stupid enough to point this to him, so now I cant do it the same way) PS: This is the most spupid task I have ever had!!! This value is not really used anythere in program, it is only fcking pointless integer.

• How can I see who in my team are writing the most code and who is writing the least using TFS?

  - by kjm

  I am having a problem with one of my team members output. He seems to be always 'busy' yet I am unable to see exactly what code he has done and he seems be delivering very little and it seems to take a long time to do so. I'd like to investigate further using TFS and was wondering if there is any functionality in TFS that shows what has been written by an individual or similar? Just to clarify I am NOT spying I am trying to resolve situation. This is only a starting point. I un derstand that quantity of code does not equate to best programmer thanks for any answers

• Why are the interpreters of all popular scripting languages written in C (if not in C at least not i

  - by wndsr

  I recently asked a question on switching from C++ to C for writing an interpreter for speed and I got a comment from someone asking why on earth I would switch to C for that. So I found out that I actually don't know why - except that C++ object oriented system has a much higher abstraction and therefore is slower. Why are the interpreters of all popular scripting languages written in C and not in C++? If you want to tell me about some other language where the interpreter for it isn't in C, please replace all occurences of popular scripting languages in this question with Ruby, Python, Perl and PHP.

• backbone.js - Having multiple instances of the same view

  - by TrueWheel

  I am having problems having multiple instances in of the same view in different div elements. When I try to initialize them only the second of the two elements appear no matter what order I put them in. Here is the code for my view. var BodyShapeView = Backbone.View.extend({ thingiview: null, scene: null, renderer: null, model: null, mouseX: 0, mouseY: 0, events:{ 'click button#front' : 'front', 'click button#diag' : 'diag', 'click button#in' : 'zoomIn', 'click button#out' : 'zoomOut', 'click button#on' : 'rotateOn', 'click button#off' : 'rotateOff', 'click button#wireframeOn' : 'wireOn', 'click button#wireframeOff' : 'wireOff', 'click button#distance' : 'dijkstra' }, initialize: function(name){ _.bindAll(this, 'render', 'animate'); scene = new THREE.Scene(); camera = new THREE.PerspectiveCamera( 15, 400 / 700, 1, 4000 ); camera.position.z = 3; scene.add( camera ); camera.position.y = -5; var ambient = new THREE.AmbientLight( 0x202020 ); scene.add( ambient ); var directionalLight = new THREE.DirectionalLight( 0xffffff, 0.75 ); directionalLight.position.set( 0, 0, 1 ); scene.add( directionalLight ); var pointLight = new THREE.PointLight( 0xffffff, 5, 29 ); pointLight.position.set( 0, -25, 10 ); scene.add( pointLight ); var loader = new THREE.OBJLoader(); loader.load( "img/originalMeanModel.obj", function ( object ) { object.children[0].geometry.computeFaceNormals(); var geometry = object.children[0].geometry; console.log(geometry); THREE.GeometryUtils.center(geometry); geometry.dynamic = true; var material = new THREE.MeshLambertMaterial({color: 0xffffff, shading: THREE.FlatShading, vertexColors: THREE.VertexColors }); mesh = new THREE.Mesh(geometry, material); model = mesh; // model = object; scene.add( model ); } ); // RENDERER renderer = new THREE.WebGLRenderer(); renderer.setSize( 400, 700 ); $(this.el).find('.obj').append( renderer.domElement ); this.animate(); }, Here is how I create the instances var morphableBody = new BodyShapeView({ el: $("#morphable-body") }); var bodyShapeView = new BodyShapeView({ el: $("#mean-body") }); Any help would be really appreciated.

• What data structure would be the least painful DataTable replacement?

  - by MatthewMartin

  I'm storing a lot of sorted ~10 row 2 column/key value pairs in ASP.NET cache-- they're the data for dropdownlists. Right now they are all DataTables, which isn't very space efficient (the rule of thumb is 10x increase in size when data is strored in a dataset). Old Code DataTable table = dataAccess.GetDataTable(); dropDownList.DataSource = table; Hoped for new Code Unknown data = dataAccess.GetSomethingMoreSpaceEfficient(); dropDownList.DataSource = data; What pre-existing datastructures are similar enough to DataTable that would minimize code breakage and reduce the serialized size when stored in ASP.NET cache?

• Virtual Pageview Goal Funnel Not Tracking Correctly

  - by cphill

  I have an AJAX form that has three stages: 1. The landing page where a user fills out a form and selects between three question sets and clicks begin assessment 2. The assessment page, where users fill out questions relating to the question set that they selected on the landing page. 3.The results page, which shows whether they are at High Risk or Low Risk. Since this is an AJAX form that does not open a new page for each step of the process, I implemented a virtual pageview that would fire on the pageload of each step of the form process. The following is my virtual pageview setup for each stage: /form/begin-assessment /form/assessment/* (* = Three different virtual pageviews depending on the users selection of the three sets of questions: /one, /two, /three) 3./form/finished-assessment I have set up three separate goals to track user progress through each step of the form assessment. Here is my Goal setup: Goal Description: -Goal Type: Destination Goal Details: -Destination: /form/finished-assessment -Funnel: On Step 1: /form/begin-assessment (Required: Yes) Step 2: /form/assessment/one (Step 2: replace /one with /two or /three and you have my two other goals setup) Now my goals are recording the correct data in the first step and show the completions in the destination, but the second step does not show any drop offs. They show the same data as the destination. Any ideas of how I set up the goals wrong?

• What characters are illegal in Cisco IOS username secret passwords?

  - by Alain O'Dea

  I am using username secret to add users with encrypted passwords to our switches and firewall. I have been battling with the same switches and firewall for a couple of hours trying to get securely generated hard passwords for all admins. Sometimes, the passwords would go into config, but wouldn't work for login. According to the documentation for enable secret a password must not begin with a number and ? has to be entered as Ctrl-V then ? to escape it. I followed that and still got passwords I could not use sometimes. There was no error when I ran username, but the password would be rejected on login by some, but not all of the switches. They are all WS-C2960-48PST-L. The passwords it didn't like contained back ticks "`" (that character under tilde ~ under Esc). The "misbehaving" switches are running: Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 12.2(50)SE5, RELEASE SOFTWARE (fc1) The "working" switches are running: Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2). The "misbehaving" switches are running a newer IOS, so this suggests a regression introduced somewhere between 12.2(46)SE and 12.2(50)SE5. I was unable to find any evidence of this being intentional in the release notes for 12.2(50)SE. I would like to avoid this next time the passwords are changed :) What characters are illegal in Cisco IOS username secret passwords? Thank you for your help :)

• Excel 2013: VLookup for cells that share common characters within cell but are both surrounded by other non-matching text

  - by Kylie Z

  I am pulling information from 2 different databases. The databases use different naming protocol for the exact same item/specified placement however they always have certain components of the name in common. The length of these names can vary throughout each of the databases (see the pic below) so I don't think counting characters would help. I need a formula (probably a vlookup/match/index of some sort) to pair up the names from the 2nd database name with the 1st database name and then place it in the adjacent column(B2) on sheet1. Until this point I've had to match, copy, and paste the pairs manually from one sheet to the other and it takes FOREVER. Any help would be much appreciated!!! For example: Database1 Name in Sheet1,A2: 728x90_Allstate_629930_ALL_JUL_2013_MASSACHUSETTSAUTO_BAN_MSN_ROSMSNAUTOSMASSACHUSETTS_7.2.13 Database2 Name in Sheet2, A13: BAN_MSN_ROSMSNAUTOSMASSACHUSETTS728X90_728X90_DFA Common Factors: "ROSMSNAUTOSMASSACHUSETTS" & "728X90" Therefore A2 and A13 need to pair up In some cases, Database 1 and 2 will have a common name aspect but sizing will be different. They need to have BOTH aspects in common in order to be paired so I would NOT want the below example to pair up. Database1 Name in Sheet1,A2: 728x90_Allstate_629930_ALL_JUL_2013_MASSACHUSETTSAUTO_BAN_MSN_ROSMSNAUTOSMASSACHUSETTS_7.2.13 Database2 Name in Sheet2, A12: BAN_MSN_ROSMSNAUTOSMASSACHUSETTS300X250_300X250_DFA Common Factor: Only "ROSMSNAUTOSMASSACHUSETTS" matches. "728x90" is not equal to "300X250" - Sizing is different so they should not be paired.

• How do I remove accents from characters in a PHP string?

  - by georgebrock

  I'm attempting to remove accents from characters in PHP string as the first step to making the string usable in a URL. I'm using the following code: $input = "Fóø Bår"; setlocale(LC_ALL, "en_US.utf8"); $output = iconv("utf-8", "ascii//TRANSLIT", $input); print($output); The output I would expect would be something like this: F'oo Bar However, instead of the accented characters being transliterated they are replaced with question marks: F?? B?r Everything I can find online indicates that setting the locale will fix this problem, however I'm already doing this. I've already checked the following details: The locale I am setting is supported by the server (included in the list produced by locale -a) The source and target encodings (UTF-8 and ASCII) are supported by the server's version of iconv (included in the list produced by iconv -l) The input string is UTF-8 encoded (verified using PHP's mb_check_encoding function, as suggested in the answer by mercator) The call to setlocale is successful (it returns 'en_US.utf8' rather than FALSE) The cause of the problem: The server is using the wrong implementation of iconv. It has the glibc version instead of the required libiconv version. Note that the iconv function on some systems may not work as you expect. In such case, it'd be a good idea to install the GNU libiconv library. It will most likely end up with more consistent results. – PHP manual's introduction to iconv Details about the iconv implementation that is used by PHP are included in the output of the phpinfo function. (I'm not able to re-compile PHP with the correct iconv library on the server I'm working with for this project so the answer I've accepted below is the one that was most useful for removing accents without iconv support.)

  i'm currently in the process of conceptualizing an art piece for a gallery show next year, so this bizarre question of mine is more than just simple curiosity. if i open up an image file (a .PNG) with Text Edit or Note Pad, the file is presented in textual characters. something like this except: æº"í=™?0Ù:Ã,ÏI8^?K¯pmDHƒÃ?;wÔlD DDF›ä™èÜE[E˜ƒê?¯ƒºäeèçã?'ów+æ1ï‡ê0òHõñ?ò$úîù¥{WÎn}2*Ÿ!y(Ö!%2e9U2µ i4Õ(?=ù(›7}:É?##„G¶VfcVñ[÷D6gvrˆvéZN›=Ù=ó{púp…p?Ók‹oÃvŒÛ»{ùœóüôøW†W–VH\P?P$VTPt^lQ‹_B_S=Q™\Z[Ü)s/{]Œ_û]~¯¿¯Awu˜ùä’JÖ Í*tï[’ÎáÔ=<Æ6?~ZCWSÛpVµ?±ØŒ?nÆ^¨æ??™¡?a¥ë£1µÒÁ#?Gè)G<^mRl™m?jˆj~€"“R–Úª’?u?çO-•m˜â?ìéväˆàˆOä5ùXùûù”]¬]?]›V›œ{X{Óˆ|Ô’Èm{J?4‰Èáæõ}??~Á?óºYáœåüuRFÆ>W|^3Ñ5‰94=,<ú?|1b=2< >ö:?sÃ`¨{úf<f|ÛÖ?ãÊ íâ–âè/_÷O¬}Â?Í›§Ãd’kÃkØ?sSíS? ??øy;-6]ˆ?÷ÌÌÙåËLÈ,l÷uvzNtÆt6Ô6?O ?P?_t_|°N¸]Ÿ{ƒ{è˜3KK> ?x~ò[ñ\ÆXA?x?Ãî?X? ?…°”¸™‘jÂzÕkm~]jObµ·p1°Y‚s?&b”}s?ãËóí-»ñ”÷‰?‡v?ˆ˜WõØ£??æe~;¸n?Ooáa'aÁÎÌ-ª$ª!ª~ ?¨‹CÏpÏO/Á›œ/?80<Ë<§8 can anyone explain what is happening here? are the characters some form translation of pixel data by the text editor? maybe it is completely meaningless / an error? if not, is there a name for this type of data conversion or process?

• Faster way to split a string and count characters using R?

  - by chrisamiller

  I'm looking for a faster way to calculate GC content for DNA strings read in from a FASTA file. This boils down to taking a string and counting the number of times that the letter 'G' or 'C' appears. I also want to specify the range of characters to consider. I have a working function that is fairly slow, and it's causing a bottleneck in my code. It looks like this: ## ## count the number of GCs in the characters between start and stop ## gcCount <- function(line, st, sp){ chars = strsplit(as.character(line),"")[[1]] numGC = 0 for(j in st:sp){ ##nested ifs faster than an OR (|) construction if(chars[[j]] == "g"){ numGC <- numGC + 1 }else if(chars[[j]] == "G"){ numGC <- numGC + 1 }else if(chars[[j]] == "c"){ numGC <- numGC + 1 }else if(chars[[j]] == "C"){ numGC <- numGC + 1 } } return(numGC) } Running Rprof gives me the following output: > a = "GCCCAAAATTTTCCGGatttaagcagacataaattcgagg" > Rprof(filename="Rprof.out") > for(i in 1:500000){gcCount(a,1,40)}; > Rprof(NULL) > summaryRprof(filename="Rprof.out") self.time self.pct total.time total.pct "gcCount" 77.36 76.8 100.74 100.0 "==" 18.30 18.2 18.30 18.2 "strsplit" 3.58 3.6 3.64 3.6 "+" 1.14 1.1 1.14 1.1 ":" 0.30 0.3 0.30 0.3 "as.logical" 0.04 0.0 0.04 0.0 "as.character" 0.02 0.0 0.02 0.0 $by.total total.time total.pct self.time self.pct "gcCount" 100.74 100.0 77.36 76.8 "==" 18.30 18.2 18.30 18.2 "strsplit" 3.64 3.6 3.58 3.6 "+" 1.14 1.1 1.14 1.1 ":" 0.30 0.3 0.30 0.3 "as.logical" 0.04 0.0 0.04 0.0 "as.character" 0.02 0.0 0.02 0.0 $sampling.time [1] 100.74 Any advice for making this code faster?

• Weird characters at the beginning of a LPTSTR? C++

  - by extintor

  I am using this code to get the windows version: define BUFSIZE 256 bool config::GetOS(LPTSTR OSv) { OSVERSIONINFOEX osve; BOOL bOsVersionInfoEx; ZeroMemory(&osve, sizeof(OSVERSIONINFOEX)); osve.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX); if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osve)) ) return false; TCHAR buf[BUFSIZE]; StringCchPrintf(buf, BUFSIZE, TEXT("%u.%u.%u.%u"), osve.dwPlatformId, osve.dwMajorVersion, osve.dwMinorVersion, osve.dwBuildNumber); StringCchCat(OSv, BUFSIZE, buf); return true; } And I am testing it with: LPTSTR OSv= new TCHAR[BUFSIZE]; config c; c.GetOS(OSv); MessageBox(OSv, 0, 0); And in the msgbox I get something like this äì5.1.20 (where 5.1.20 is = to OSv) but the first 2 or 3 chars are some weird characters that I don't know when they came from. Even stranger, if I call that second piece again it shows it ok, it only show the weird characters the first time I execute it. Does someone has an idea what's going on here?

• Which Perl moudle can handle variety of date formats with unicode characters ?

  - by ram

  My requirement is parsing xml files which contains wide varieties of timestamps based on the locales at which they are written. They may contain Unicode characters in case of Chinese or Korean locales. I have to parse these timestamps and put then in a standard format something like 2009-11-26 12:40:54 to put them in a oracle database. Sometimes I may not even know the locale and yet I have to parse the timestamps. I am looking for a module that automatically detects the timestamp format (including unicode characters for am and pm in their local language) and converts in to epoch time so that I can convert it back to what ever way I like to. I have gone through similar questions in this forum. Few suggested DateFormat module, and Date::Parse module. The perl distribution I am using is 5.10 so Date::Manip doesn't come as a core module. As I am supposed to use just the basic core modules and few CPAN modules(on request I cannot ask for all), I request you to kindly suggest me a good module that suffices all my requirements. Thanks in advance
