• Excel export displaying '#####...'

  - by Cypher

  I'm trying to export an Excel database into .txt (Tab Delimited), but some of my cells are quite large. When I export into a txt some of the cells are exported as '#######....' which is surprisingly useless. Has this happened to anyone else? Do you know an easy fix?

• What is the worst programming language you ever worked with? [closed]

  - by Ludwig Weinzierl

  If you have an interesting story to share, please post an answer, but do not abuse this question for bashing a language. We are programmers, and our primary tool is the programming language we use. While there is a lot of discussion about the best one, I'd like to hear your stories about the worst programming languages you ever worked with and I'd like to know exactly what annoyed you. I'd like to collect this stories partly to avoid common pitfalls while designing a language (especially a DSL) and partly to avoid quirky languages in the future in general. This question is not subjective. If a language supports only single character identifiers (see my own answer) this is bad in a non-debatable way. EDIT Some people have raised concerns that this question attracts trolls. Wading through all your answers made one thing clear. The large majority of answers is appropriate, useful and well written. UPDATE 2009-07-01 19:15 GMT The language overview is now complete, covering 103 different languages from 102 answers. I decided to be lax about what counts as a programming language and included anything reasonable. Thank you David for your comments on this. Here are all programming languages covered so far (alphabetical order, linked with answer, new entries in bold): ABAP, all 20th century languages, all drag and drop languages, all proprietary languages, APF, APL (1), AS400, Authorware, Autohotkey, BancaStar, BASIC, Bourne Shell, Brainfuck, C++, Centura Team Developer, Cobol (1), Cold Fusion, Coldfusion, CRM114, Crystal Syntax, CSS, Dataflex 2.3, DB/c DX, dbase II, DCL, Delphi IDE, Doors DXL, DOS batch (1), Excel Macro language, FileMaker, FOCUS, Forth, FORTRAN, FORTRAN 77, HTML, Illustra web blade, Informix 4th Generation Language, Informix Universal Server web blade, INTERCAL, Java, JavaScript (1), JCL (1), karol, LabTalk, Labview, Lingo, LISP, Logo, LOLCODE, LotusScript, m4, Magic II, Makefiles, MapBasic, MaxScript, Meditech Magic, MEL, mIRC Script, MS Access, MUMPS, Oberon, object extensions to C, Objective-C, OPS5, Oz, Perl (1), PHP, PL/SQL, PowerDynamo, PROGRESS 4GL, prova, PS-FOCUS, Python, Regular Expressions, RPG, RPG II, Scheme, ScriptMaker, sendmail.conf, Smalltalk, Smalltalk , SNOBOL, SpeedScript, Sybase PowerBuilder, Symbian C++, System RPL, TCL, TECO, The Visual Software Environment, Tiny praat, TransCAD, troff, uBasic, VB6 (1), VBScript (1), VDF4, Vimscript, Visual Basic (1), Visual C++, Visual Foxpro, VSE, Webspeed, XSLT The answers covering 80386 assembler, VB6 and VBScript have been removed.

• MS Ajax FilteredTextBox stopped working

  - by TenaciousImpy

  Hi, I'm using Microsoft's AJAX library via their CDN. Everything was going fine in an old project. I then created a new project and copied and pasted some of the AJAX code hoping that it would work. However, my code isn't working and I've been struggling to figure out why. I'm trying to implement a filtered textbox: <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="http://ajax.microsoft.com/ajax/beta/0911/Start.debug.js" type="text/javascript"></script> <script src="http://ajax.microsoft.com/ajax/beta/0911/extended/ExtendedControls.debug.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { Sys.require(Sys.components.filteredTextBox, function() { $("[id$='UserName']").filteredTextBox({ InvalidChars: ".", FilterType: Sys.Extended.UI.FilterTypes.Numbers | Sys.Extended.UI.FilterTypes.UppercaseLetters | Sys.Extended.UI.FilterTypes.LowercaseLetters | Sys.Extended.UI.FilterTypes.Custom, FilterMode: Sys.Extended.UI.FilterModes.ValidChars }); }); }); </script> When I run this, the textbox isn't filtered and I can enter any character. In Chrome, I used the Dev Tools and it found two errors on the page. In my .aspx page, I have: Uncaught TypeError: Cannot read property 'Numbers' of undefined (regarding the Sys.Extended.UI.FilterTypes.Numbers in the code above). In filteredtextboxbehavior.debug.js, I have the error: Uncaught TypeError: Object #<an Object> has no method 'registerComponent' Any ideas why I'm getting this error? The code has been working previously so I'm not sure if I had added any extra settings in my old project which the new one doesn't have. Thanks! ps:The textbox can be found as any other actions on it are recognized.

• Django: Unicode Filenames with ASCII headers?

  - by TheLizardKing

  I have a list of strangely encoded files: 02 - Charlie, Woody and You/Study #22.mp3 which I suppose isn't so bad but there are a few particular characters which Django OR nginx seem to be snagging on. >>> test = u'02 - Charlie, Woody and You/Study #22.mp3' >>> test u'02 - Charlie, Woody and You\uff0fStudy #22.mp3' I am using nginx as a reverse proxy to connect to django's built in webserver (still in development stages) and postgresql for my database. My database and tables are all en_US.UTF-8 and I am using pgadmin3 to view my tables outside of django. My issue goes a little beyond my title, firstly how should I be saving possibly whacky filenames in my database? My current method is 'path': smart_unicode(path.lstrip(MUSIC_PATH)), 'filename': smart_unicode(file) and when I pprint out the values they do show u'whateverthecrap' I am not sure if that is how I should be doing it but assuming it is now I have issues trying to spit out the download. My download view looks something like this: def song_download(request, song_id): song = get_object_or_404(Song, pk=song_id) url = u'/static_music/%s/%s' % (song.path, song.filename) print url response = HttpResponse() response['X-Accel-Redirect'] = url response['Content-Type'] = 'audio/mpeg' response['Content-Disposition'] = "attachment; filename=test.mp3" return response and most files will download but when I get to 02 - Charlie, Woody and You/Study #22.mp3 I receive this from django: 'ascii' codec can't encode character u'\uff0f' in position 118: ordinal not in range(128), HTTP response headers must be in US-ASCII format. How can I use an ASCII acceptable string if my filename is out of bounds? 02 - Charlie, Woody and You\uff0fStudy #22.mp3 doesn't seem to work... EDIT 1 I am using Ubuntu for my OS.

• auto Focus (Hit Enter) Javascript function is working good in IE7 but not working in IE8

  - by James123

  Hi, I used a javascript FocusChange() in my aspx page. I have couple of controls and I need Hit enter key need to move next control based on tab index. It is working good in IE7 but not working in IE8... Please help me on this.. Thanks for your help in advance.

• emacs frustration with web development any working dot-files?

  - by Tony Cruise

  I really liked flexibility of emacs but it is really annoying to make it work. I want to use it for web development html, css, javascript, php. I first tried emacs-starter-kit . It didn't included nXhtml. Also C-g key binding does not work (they call it starter kit but basic key command does not work). I think it is mapped for git control. That's a frustration for a beginner. Then I replaced emacs-starter-kit with nXhtml. At least C-g is working. But code completion sucks, M-tab does not work. I tried code completion from nXhtml menu with no success. Also NXhtml mode did'nt colorized my file if css is mixed with html. Isn't it recommended for mixed html, css,php files. So why it doesnt work?. Why Emacs folks do not aware of convention over configuration? Dam! ship it something works! Please help me before I am getting crazy. I use Ubuntu 10.04 and emacs-snaphot-gtk 23.1.50-1. Please guide me step by step with your working dotfile url. Even I accept I am a dummy, it is really annoying and frustrating to use emacs.

• JSON/PrototypeJS - why does this only work SOMETIMES?

  - by koko

  This is driving me nuts! I'm getting some JSON from my server: {"id262":{"done":null,"status":null,"verfall":null,"id":262,"bid":20044,"art":"owner","uid":"demo02","aktion":null,"termin_datum":null,"docid":null,"gruppenid":null,"news":"newsstring","datum":"11.06.2010","header":"headerstring","for_uid":"demo01"}, "id263":{"done":null,"status":"pending","verfall":null,"bid":20044,"id":263,"uid":"demo02","art":"foo","aktion":"dosomething","termin_datum":"11.06.2010","docid":null,"gruppenid":null,"datum":"11.06.2010","news":"newsstring","for_uid":"demo01","header":"headerstring"}, "id261":{"done":null,"status":null,"verfall":null,"id":261,"bid":20044,"art":"termin","uid":"demo02","aktion":null,"termin_datum":"25.06.2010","docid":null,"gruppenid":null,"news":"newsstring","datum":"11.06.2010","header":"headerstring","for_uid":null}} This is how my JS looks like: var user = 'demo02'; new Ajax.Request('myscript.pl?someparameter=value', { method:'get', onSuccess: function(transport){ var db_json = transport.responseText.evalJSON(), propCount = 0, someArray1 = [], someArray2 = [], otherArray = []; //JSON DEBUG console.log('validated string:'); console.log(transport.responseText.evalJSON(true)); for(var prop in db_json) { propCount++; if ( (db_json[prop].art == 'foo') && (db_json[prop].for_uid == user) ) { someArray1.push(db_json[prop]); } else if( (db_json[prop].art == 'foo') && (db_json[prop].uid == user) ) { someArray2.push(db_json[prop]); } else if( db_json[prop].art == 'log' ) { otherArray.push(db_json[prop]); } } if(someArray1.length>0) { someArray1.map(function(el){ $('someArray1target').innerHTML += el.done; //do more stuff }); } if(someArray2.length>0) { someArray2.map(function(el){ $('someArray2target').innerHTML += el.done; //do more stuff }); } }); Sometimes, it works perfectly. Sometimes, i get my JSON String (it appears in Firebug's "answer"-tab), but it won't log the JSON in console-log(). I'm not getting any errors and javascript is still working. Next time after reloading, it might work, but it might not. I cannot remotely imagine why this only happens sometimes!

• drawing different quartz 2d

  - by Cosizzle

  Hello, I'm trying to make a small application or demo thats a tab bar application. Each bar item loads in a new view. I've created a quartzView class that is called on by the controller: - (void)viewDidLoad { quartzView *drawingView = [[quartzView alloc] initWithFrame:CGRectMake(0,0,320,480)]; [self.view addSubview:drawingView]; [super viewDidLoad]; } From my understanding, the drawRect method must be triggered in order to render the object and to draw it. This is my quartzView class: #import "quartzView.h" @implementation quartzView #pragma mark shapes // Blue Circle - (void)drawRect:(CGRect)rect { NSLog(@"Trying to draw..."); CGContextRef ctx = UIGraphicsGetCurrentContext(); //get the current context CGContextClearRect(ctx, rect); //clear off the screen //draw a red square CGContextSetRGBFillColor(ctx, 255, 0, 0, 1); CGContextFillRect(ctx, CGRectMake(10, 10, 50, 50)); } // ==================================================================================================== #pragma mark - - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)dealloc { [super dealloc]; } @end So how would I go about to say, if the view is view one, draw a square if it's view two draw a circle. And so on.

• Encrypting with Perl CBC and decrypting with PHP mcrypt

  - by Ed

  I have an encrypted string that was encrypted with Perl Crypt::CBC (Rijndael,cbc). The original plaintext was encrypted with encrypt_hex() method of Crypt::CBC. $encrypted_string = '52616e646f6d49567b2c89810ceddbe8d182c23ba5f6562a418e318b803a370ea25a6a8cbfe82bc6362f790821dce8441a790a7d25d3d9ea29f86e6685d0796d'; I have the 32 character key that was used. mcrypt is successfully compiled into PHP, but I'm having a very hard time trying to decrypt the string in PHP. I keep getting gibberish back. If I unpack('H*', $encrypted_string), I see 'RandomIV' followed by what looks like binary. I can't seem to correctly extract the IV and separate the actual encrypted message. I know I'm not providing my information, but I'm not sure where else to start. $cipher = 'rijndael-256'; $cipher_mode = 'cbc'; $td = mcrypt_module_open($cipher, '', $cipher_mode, ''); $key = '32 characters'; // Does this need to converted to something else before being passed? $iv = ?? // Not sure how to extract this from $encrypted_string. $token = ?? // Should be a sub-string of $encrypted_string, correct? mcrypt_generic_init($td, $key, $iv); $clear = rtrim(mdecrypt_generic($td, $token), ''); mcrypt_generic_deinit($td); mcrypt_module_close($td); echo $clear; Any help, pointers in the right direction, would be greatly appreciated. Let me know if I need to provide more information.

• Why does ICEfaces send dispose-window request on page unload when using view-scoped bean?

  - by woflrevo

  in our application ICEfaces always sends a dispose-window request just before navigating to another JSF Page. as much as i understand this should not happen when having org.icefaces.lazyWindowScope set to true and there is no window-scoped bean involved in current request. but it happens on each link and makes our UI less responsive. but we don't have any window-scoped bean in our application. is that a bug in icefaces that the dispose request is sent when using view-scoped beans? Is it possible to disable? ViewScope is defined in JSF not in ICEfaces, it should work without this dispose request i guess... @ManagedBean(name="viewScopeBean") @ViewScoped public class ViewScopeBean { public void doSomething(){ // } } And here the example jsf: <ice:form> <ice:commandButton value="doSomething" action="#{viewScopeBean.doSomething}"/> <h:link outcome="index" value="Link to same page"/> </ice:form> To reproduce do the following using the code above: open firebug's net tab and activate persist option click doSomething-Button click "link to same page" = dispose-window will be send before navigation Dispose Request Parameters: ice.submit.type=ice.dispose.window ice.window=4guthcbue javax.faces.ViewState=-8138151632882151449%3A-6709064564386098402 Environment: ICEfaces-EE 2.0.0.GA ICEpush-EE 2.0.0.GA Mojarra 2.1.1 JRockit 1.6.0_22 WebLogic Server 10.3.4.0 ICEfaces Configuration: org.icefaces.render.auto: true [default] org.icefaces.autoid: true [default] org.icefaces.aria.enabled: true [default] org.icefaces.blockUIOnSubmit: false [default] org.icefaces.compressDOM: false [default] org.icefaces.compressResources: true [default] org.icefaces.connectionLostRedirectURI: /pages/main.jsf org.icefaces.deltaSubmit: false [default] org.icefaces.lazyPush: true [default] org.icefaces.sessionExpiredRedirectURI: /pages/main.jsf org.icefaces.standardFormSerialization: false [default] org.icefaces.strictSessionTimeout: false [default] org.icefaces.windowScopeExpiration = 1000 [default] org.icefaces.mandatoryResourceConfiguration: null [default] org.icefaces.uniqueResourceURLs: true [default] org.icefaces.lazyWindowScope: true [default] org.icefaces.disableDefaultErrorPopups: false [default]

• Nested Routes and Parameters for Rails URLs (Best Practice)

  - by viatropos

  Hey there, I have a decent understanding of RESTful urls and all the theory behind not nesting urls, but I'm still not quite sure how this looks in an enterprise application, like something like Amazon, StackOverflow, or Google... Google has urls like this: http://code.google.com/apis/ajax/ http://code.google.com/apis/maps/documentation/staticmaps/ https://www.google.com/calendar/render?tab=mc Amazon like this: http://www.amazon.com/books-used-books-textbooks/b/ref=sa_menu_bo0?ie=UTF8&node=283155&pf_rd_p=328655101&pf_rd_s=left-nav-1&pf_rd_t=101&pf_rd_i=507846&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1PK4ZKN4YWJJ9B86ANC9 http://www.amazon.com/Ruby-Programming-Language-David-Flanagan/dp/0596516177/ref=sr_1_1?ie=UTF8&s=books&qid=1258755625&sr=1-1 And StackOverflow like this: http://stackoverflow.com/users/169992/viatropos http://stackoverflow.com/questions/tagged/html http://stackoverflow.com/questions/tagged?tagnames=html&sort=newest&pagesize=15 So my question is, what is best practice in terms of creating urls for systems like these? When do you start storing parameters in the url, when don't you? These big companies don't seem to be following the rules so hotly debated in the ruby community (that you should almost never nest URLs for example), so I'm wondering how you go about implementing your own urls in larger scale projects because it seems like the idea of not nesting urls breaks down at anything larger than a blog. Any tips?

• How can I convert this PHP script to Ruby? (build tree from tabbed string)

  I found this script below online, and I'm wondering how I can do the same thing with a Ruby on Rails setup.

• Constant NSDictionary/NSArray for class methods.

  - by Jeff B

  I am trying to code a global lookup table of sorts. I have game data that is stored in character/string format in a plist, but which needs to be in integer/id format when it is loaded. For instance, in the level data file, a "p" means player. In the game code a player is represented as the integer 1. This let's me do some bitwise operations, etc. I am simplifying greatly here, but trying to get the point across. Also, there is a conversion to coordinates for the sprite on a sprite sheet. Right now this string-integer, integer-string, integer-coordinate, etc. conversion is taking place in several places in code using a case statement. This stinks, of course, and I would rather do it with a dictionary lookup. I created a class called levelInfo, and want to define the dictionary for this conversion, and then class methods to call when I need to do a conversion, or otherwise deal with level data. NSString *levelObjects = @"empty,player,object,thing,doohickey"; int levelIDs[] = [0,1,2,4,8]; // etc etc @implementation LevelInfo +(int) crateIDfromChar: (char) crateChar { int idx = [[crateTypes componentsSeparatedByString:@","] indexOfObject: crateChar]; return levelIDs[idx]; } +(NSString *) crateStringFromID: (int) crateID { return [[crateTypes componentsSeparatedByString:@","] objectAtIndex: crateID]; } @end Is there a better way to do this? It feels wrong to basically build these temporary arrays, or dictionaries, or whatever for each call to do this translation. And I don't know of a way to declare a constant NSArray or NSDictionary. Please, tell me a better way....

• Is there any open source tool that automatically 'detects' email threading like Gmail?

  - by Chris W.

  For instance, if the original message (message 1) is... Hey Jon, Want to go get some pizza? -Bill And the reply (message 2) is... Bill, Sorry, I can't make lunch today. Jonathon Parks, CTO Acme Systems On Wed, Feb 24, 2010 at 4:43 PM, Bill Waters wrote: Hey John, Want to go get some pizza? -Bill In Gmail, the system (a) detects that message 2 is a reply to message 1 and turns this into a 'thread' of sorts and (b) detects where the replied portion of the message actually is and hides it from the user. (In this case the hidden portion would start at "On Wed, Feb..." and continue to the end of the message.) Obviously, in this simple example it would be easy to detect the "On <Date, <Name wrote:" or the "" character prefixes. But many email systems have many different style of marking replies (not to mention HTML emails). I get the feeling that you would have to have some damn smart string parsing algorithms to get anywhere near how good GMail's is. Does this technology already exist in an open source project somewhere? Either in some library devoted to this exclusively or perhaps in some open source email client that does similar message threading? Thanks.

• finding "line-breaks" in textarea that is word-wrapping ARABIC text

  - by Irfan jamal

  I have a string of text that I display in a textarea (right-to-left orientation). The user can resize the textarea dynamically (I use jquery for this) and the text will wrap as necessary. When the user hits submit, I will take that text and create an image using PHP, BUT before submitting I would like to know where the "line-breaks" or rather "word-wraps" occur. Everywhere I have looked so far only shows me how to process line-breaks on the php side. I want to make it clear that there ARE NO LINE-BREAKS. What I have is one LONG string that will be word-wrapped in different ways based on the width of the textarea set by the user. I can't use "columns" or any other standard width representation because I have a very complex arabic font that is actually composed of glyphs (characters) of numerous different widths. If anyone knows of a way of accessing where the word wraps occur (either in a textarea or a div if need-be), I'd really like to know. My only other solution is to actually store (in my DB) the width of every single character (somewhat tedious since there are over 200 characters in 600 different fonts, for a total of...some huge number). My hopes aren't high, but I thought I would ask. Thanks i. jamal

• How do I get 3 lines of text from a paragraph

  - by Keltex

  I'm trying to create an "snippet" from a paragraph. I have a long paragraph of text with a word hilighted in the middle. I want to get the line containing the word before that line and the line after that line. I have the following piece of information: The text (in a string) The lines are deliminated by a NEWLINE character \n I have the index into the string of the text I want to hilight A couple other criteria: If my word falls on first line of the paragraph, it should show the 1st 3 lines If my word falls on the last line of the paragraph, it should show the last 3 lines Should show the entire paragraph in the degenative cases (the paragraph only has 1 or 2 lines) Here's an example: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph Example, if my index points to BIRD, it should show lines 1, 2, & 3 as one complete string like this: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph If my index points to DOG, it should show lines 3, 4, & 5 as one complete string like this: This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph etc. Anybody want to help tackle this?

• How to deploy a WPF 4 Full Trust XBAP an on intranet?

  - by sparks

  I'm having trouble running a full trust WPF 4 XBAP (browser application), created with Visual Studio 2010, from my intranet. I do not get a ClickOnce elevation prompt, as described in ScottGu's post on WPF 4: Full Trust XBAP Deployment Starting in WPF 4, the ClickOnce elevation prompt is also enabled for XAML Browser Applications (XBAPs) in Intranet and Trusted Zones, making it easier to deploy full-trust XBAPs. For XBAPs that require security permissions greater than the minimum code access security (CAS) permission grantset of the Intranet and Trusted Zones, the user will be able to click 'Run' on the ClickOnce elevation prompt when they navigate to the XBAP to allow the XBAP to run with the requested permissions. Instead, I get the "Trust Not Granted" message. I'm running the application in two ways; in both cases, I get the "Trust Not Granted" message. First, I'm launching the application by double-clicking on the xbap file from my NAS on the local network. Secondly, I'm also trying to launch the application when it is hosted on a website via IIS from the same machine. Are both of these scenarios considered to be run from an "intranet?" Or does "intranet" mean some in particular here? Or am I doing something completely wrong? Of note, I am able to launch the application without problem when I simply double-click the xbap from my local computer. The xbap in question was created specifically to test the ClickOnce elevation prompt. It was created with Visual Studio 2010 as a WPF Browser Application. The only change I made was to change this to a full trust application (My Project Security tab This is a full trust application). In the publish wizard, I am choosing the following: Where do you want to publish the application? - I chose to publish to a local directory How will user install the application? - I chose "From a CD-ROM or DVD-ROM" Will the application be available offline - All choices were grayed out

• URL Encoding using C#

  - by masfenix

  I have an application which I've developed for a friend. It sends a POST request to the VB forum software and logs someone in (with out setting cookies or anything). Once the user is logged in I create a variable that creates a path on their local machine. c:\tempfolder\date\username The problem is that some usernames are throwing "Illegal chars" exception. For example if my username was mas|fenix it would throw an exception.. Path.Combine( _ Environment.GetFolderPath(System.Environment.SpecialFolder.CommonApplicationData), _ DateTime.Now.ToString("ddMMyyhhmm") + "-" + form1.username) I don't want to remove it from the string, but a folder with their username is created through FTP on a server. And this leads to my second question. If I am creating a folder on the server can I leave the "illegal chars" in? I only ask this because the server is Linux based, and I am not sure if Linux accepts it or not.. EDIT: It seems that URL encode is NOT what I want.. Here's what I want to do: old username = mas|fenix new username = mas%xxfenix Where %xx is the ASCII value or any other value that would easily identify the character.

• Marshal.StringToCoTaskMemAnsi converting non-Latin characters when sending raw data to a printer

  - by rem

  For sending raw data to a thermal DATAMAX printer I'm using RawPrinterHelper class from this Microsoft KB article. When a string sent to printer contains only Latin characters, everything is OK. But non-Latin, in my case Russian characters in a string, are not printed correct. I think the problem is in using Marshal.StringToCoTaskMemAnsi method for converting the string: public static bool SendStringToPrinter(string szPrinterName, string szString) { IntPtr pBytes; Int32 dwCount; // How many characters are in the string? dwCount = szString.Length; // Assume that the printer is expecting ANSI text, and then convert // the string to ANSI text. pBytes = Marshal.StringToCoTaskMemAnsi(szString); // Send the converted ANSI string to the printer. SendBytesToPrinter(szPrinterName, pBytes, dwCount); Marshal.FreeCoTaskMem(pBytes); return true; } Just to note, Russian characters in the string are put in hex format, like "\x83", but nevertheless the method doesn't put this hex value in unmanaged memory as it is, but converts it, I think, according with ANSI code page to a character and then printer can not read it correctly. If I try to compose a file, using Hex editor and put correct hex values in place of non-Latin characters and then send the file to a printer using another method from the same class SendFileToPrinter, everything, including Russian characters is printed correctly. How in this case the problem with sending string, containing non-Latin characters, could be solved?

• what's the alternative to readonlycollection when using lazy="extra"?

  - by Kunjan

  I am trying to use lazy="extra" for the child collection of Trades I have on my Client object. The trades is an Iset<Trade Trades, exposed as ReadOnlyCollection<Trade because I do not want anyone to modify the collection directly. As a result, I have added AddTrade and RemoveTrade methods. Now I have a Client Search page where I need to show the Trade Count. and on the Client details page I have a tab where I need to show all the trades for the Client in paged gridview. What I want to achieve is, for the search when I say on the client object as client.Trades.Count, nHibernate should only fire a select count(*) query. Hence I am using lazy="extra". But because I am using a ReadOnlyCollection, nHibernate fires a count query & a separate query to load the child collection trades completely. Also, I cannot include the Trades in my initial search request as this would disturb the paging because a counterparty can have n trades which would result in n rows, when I am searching clients only. So the child collections have to be loaded lazily. The second problem is that on the client details page -- Trades grid view, I have enabled paging for performance reasons. But by nature nHibernate loads the entire collection of trades as the user goes from one page to another. Ideally I want to control this by getting only trades specific to the page the user is on. How can I achieve this? I came across this very good article. http://stackoverflow.com/questions/876976/implementing-ipagedlistt-on-my-models-using-nhibernate But I am not sure if this will work for me, as lazy=extra currently doesnt work as expected with the ReadOnlyCollection. So, if I went ahead and implemented the solution this way and further enhanced it by making the List/Set Immutable, will lazy=extra give me the same problem as with ReadOnlyCollections?

• How to publish an ASP.NET MVC website

  - by Luke Puplett

  Hello -- I've a site that I'd like to publish to a co-located live server. I'm finding this simple task quite hard. My problems begin with the Web Deploy tool (1.1) giving me a 401 Unauthorized as the adminstrator because port :8172 comes up in the errors and this port is blocked - but the documentation says "The default ListenURL is http://+:80/MsDeployAgentService"! I'm loathe to open another port and I've little patience these days so I thought bu66er it, I'll create a Web Deploy package and import it into IIS on the server over RDP. I notice first that Visual Studio doesn't use a dialog box to gather settings, or use my Publish profiles but seems to use a tab in the project properties, although I think these are ignored when importing the package anyway? I'm now sitting in the import wizard with Application Path and Connection String. I've cleared the conn string as I think this is for some ASP stuff I don't use but when I enter nothing in the Application Path, the wizard barks at me saying that basically I'm a weirdo because most people publish to folders beneath the root site. Now, I want my site to be site.com/Home/About and not site.com/subfolder/Home/About and I think being an MVC routed site that a subfolder will introduce other headaches. Should I go ahead and use the root? Finally, I also want to publish a web service to www.site.com/services/soap which I think IIS can handle. While typing this question, Amazon have delivered my IIS 7 Resource Kit, and I've been scouring the internet but actually I'm getting more confused. Comment here seems to show consensus opinion that Publish isn't for production sites and that real men roll their own. http://stackoverflow.com/questions/260525/asp-net-website-publish-vs-web-deployment-project ...I guess this was pre- Web Deployment Tool era? I'm going to experiment on a spare box for now but any assistance is welcome. Luke

• Fluid CSS: float column with overflow

  - by Ates Goral

  I'm using a fluid layout in the new theme that I'm working on for my blog. I often blog about code and include <pre> blocks within the posts. The float: left column for the content area has a max-width so that the column stops at a certain maximum width and can also be shrunk: +----------+ +------+ | text | | text | | | | | | | | | | | | | | | | | | | | | +----------+ +------+ max shrunk What I want is for the <pre> elements to be wider than the text column so that I can fit 80-character-wrapped code without horizontal scroll bars. But I want the <pre> elements to overflow from the content area, without affecting its fluidity: +----------+ +------+ | text | | text | | | | | +----------+--+ +------+------+ | code | | code | +----------+--+ +------+------+ | | | | +----------+ +------+ max shrunk But, max-width stops being fluid once I insert the overhanging <pre> in there: the width of the column remains at the specified max-width even when I shrink the browser beyond that width. I've played around with a bare-minimum scenario to reproduce the problem and noticed that doing either of the following brings back the fluidity: Remove the <pre> (doh...) Remove the float: left The workaround I'm currently using is to insert the <pre> elements into "breaks" in the post column, so that the widths of the post segments and the <pre> segments are managed mutually exclusively: +----------+ +------+ | text | | text | +----------+ +------+ +-------------+ +-------------+ | code | | code | +-------------+ +-------------+ +----------+ +------+ +----------+ +------+ max shrunk But this forces me to insert additional closing and opening <div> elements into the post text which I'd rather keep semantically pristine. Admittedly, I don't have a full grasp of how the box model works with floats with overflowing content, so I don't understand why the combination of float: left on the container and the <pre> inside it cripple the max-width of the container. I'm observing the same problem on Firefox/Chrome/Safari/Opera. IE6 (the crazy one) seems happy all the time. This also doesn't seem dependent on quirks/standards mode.

• Getting Android SDK WebView and TabWidget to play nice

  - by jdandrea

  I’m taking the HelloTabWidget Android example and trying two things: Moving the tabs to the bottom vs. the top (if that’s even desirable from an Android UI POV) Making each tab show a particular WebView in the space above I’ve got this for a layout (high level): <TabHost> <LinearLayout> <FrameLayout> <WebView/> <WebView/> <WebView/> <WebView/> <WebView/> </FrameLayout> <TabWidget/> </LinearLayout> </TabHost> Everything has a width/height set to fill_parent except for the TabWidget which has its layout_height set to wrap_content (and the layout_gravity set to bottom). First thing I noticed is that WebViews don’t show anything until all the parents have width/height set to fill_parent. However, once I do that, they fill the entire display, obscuring the TabWidget. Is there some other trick to making these two views play nicely together?

• NoSuchMethod exception thrown in GWT

  - by eb1

  I'm starting to get my feet wet in the latest Google Web Toolkit using the Eclipse plugin on OS X 10.5.8. So far I've been able to get the client up and running, which is great. The server, though, is a different matter. I'm trying to link to a .jar file that has some classes I want to use in a server ServiceImpl class, but it seems to have glommed onto a previous iteration of the .jar - I've added a method, rebuilt the jar, removed the jar from the libraries tab on the GWT project's build path (as well as on the exports) and reincluded the jar. No luck - I'm still getting: [WARN] Exception while dispatching incoming RPC call com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract org.gwtapplication.client.LWDocument org.gwtapplication.client.DocumentService.getDocument()' threw an unexpected exception: java.lang.NoSuchMethodError: org.externalmodel.MyReallyValidClass.toSomething()Ljava/lang/String; at com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java:378) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:581) ...

Any clue where I should be looking?
