  • CSS overflow and word-wrap behaviour not helping me at all

    - by henriquev
    You can see how the filename field should look at http://www.plifk.com/henvic/114 and how it breaks the layout at http://www.plifk.com/henvic/159 If I used 108574main-neutron-star-and-a-very-bad-overfow-will-happen-here-so-sad.mpg I would not get an overflow, but in the first line "108574main-neutron-star-and-a-very-" and in the second line a "bad-overfow-happens.mpg". What can I do to avoid getting an overflow? Please know that I don't want to use quirks (like PHP's wordwrap, neither JavaScript if possible) and I've tried some ways in CSS with word-wrap, etc, but nothing worked out. I've also tried word-break: break-all (tested on Firefox only) but it didn't work also. Even the overflow: hidden; is not working... I'm not very familiar with web designing (indeed I try to do everything by the standards, etc) and I'm completely lost right now. The uncompressed CSS file can be seen at http://pastebin.ca/1802451 Now... I really understand that this is expected once the word-wrap is supposed for text, not characters. But hey, even with break-all it doesn't do anything. How can? Thank you very much in advance.

  • How to parse a raw HTTP response?

    - by Ed
    If I have a raw HTTP response as a string: HTTP/1.1 200 OK Date: Tue, 11 May 2010 07:28:30 GMT Expires: -1 Cache-Control: private, max-age=0 Content-Type: text/html; charset=UTF-8 Server: gws X-XSS-Protection: 1; mode=block Connection: close <!doctype html><html>...</html> Is there an easy way I can parse it into an HttpListenerResponse object? Or at least some kind .NET object so I don't have to work with raw responses. What I'm doing currently is extracting the header key/value pairs and setting them on the HttpListenerResponse. But some headers can't be set, and then I have to cut out the body of the response and write it to the OutputStream. But the body could be gzipped, or it could be an image, which I can't get to work yet. And some responses contain random characters everywhere, which looks like an encoding problem. It's a lot of trouble. I'm getting a raw response because I'm using SOCKS to send an HTTP request. The program I'm working on is basically an HTTP proxy that can route requests through a SOCKS proxy, like Privoxy does.

  • Measuring text with sizeWithFont returns height one line too short

    - by Mac
    In an iPhone app I'm working on, I'm trying to get a UILabel to dynamically adjust its size based on its content. To do so, I'm using NSString's sizeWithFont:constrainedToSize method to measure the height of the text when constrained to a given width, and then set the UILabel to that width and the returned height. The problem however, is that roughly half the time sizeWithFont is returning a height for the text that is one line too short. This happens mostly with long strings (a couple of hundred characters), but also very occasionally with shorter strings (less than one hundred). For reference, my code looks like the following (textLabel is the UILabel in question and is a member variable, TEXT_WIDTH is the desired label width): - (void) setLabelText:(NSString*) text { CGSize bounds = CGSizeMake(TEXT_WIDTH, CGFLOAT_MAX); int textHeight = [text sizeWithFont:textLabel constrainedToSize:bounds lineBreakMode:UILineBreakModeWordWrap].height; CGRect newFrame = CGRectMake(0, 0, TEXT_WIDTH, textHeight); [textLabel setFrame:newFrame]; } Just to be clear, I don't believe the issue is with the UILabel, as I've manually inspected the value being returned by sizeWithFont and can confirm that the number being returned for the height is too small on the occasions when the label is also too small.

  • IE innerHTML chops sentence if the last word contains '&' (ampersand)

    - by Mandai
    I am trying to populate a DOM element with ID 'myElement'. The content which I'm populating is a mix of text and HTML elements. Assume following is the content I wish to populate in my DOM element. var x = "<b>Success</b> is a matter of hard work &luck"; I tried using innerHTML as follows, document.getElementById("myElement").innerHTML=x; This resulted in chopping off of the last word in my sentence. Apparently, the problem is due to the '&' character present in the last word. I played around with the '&' and innerHTML and following are my observations. If the last word of the content is less than 10 characters and if it has a '&' character present in it, innerHTML chops off the sentence at '&'. This problem does not happen in firefox. If I use innerText the last word is in tact but then all the HTML tags which are part of the content becomes plain text. I tried populating through jQuery's #html method, $("#myElement").html(x); This approach solves the problem in IE but not in chrome. How can I insert a HTML content with a last word containing '&' without it being chopped off in all browsers?

  • vbCrLf in Multiline TextBox shows up only when .Trim() is called

    - by Brandon Montgomery
    I have an ASP TextBox with TextMode set to MultiLine. I'm having problems with preserving the vbCrLf characters when a user tries to put line breaks into the text. When a button on the page is pressed, I'm taking the text from the control, trimming it using String.Trim, and assigning that value to a String property on an object (which, in turn assigns it to a private internal String variable on the object). The object then takes the value from the private internal variable and throws it into the database using a stored procedure call (the SP parameter it is put into is an nvarchar(4000)). ASPX Page: <asp:UpdatePanel ID="UpdatePanel2" runat="server" RenderMode="Inline" UpdateMode="Conditional" ChildrenAsTriggers="true"> <ContentTemplate> <!-- some other controls and things --> <asp:TextBox TextMode="MultiLine" runat="server" ID="txtComments" Width="100%" Height="60px" CssClass="TDTextArea" Style="border: 0px;" MaxLength="2000" /> <!-- some other controls and things --> </ContentTemplate> </asp:UpdatePanel> code behind: ProjectRequest.StatusComments = txtComments.Text.Trim object property: Protected mStatusComments As String = String.Empty Property StatusComments() As String Get Return mStatusComments.Trim End Get Set(ByVal Value As String) mStatusComments = Value End Set End Property stored proc call: Common.RunSP(mDBConnStr, "ProjectStatusUpdate", _ Common.MP("@UID", SqlDbType.NVarChar, 40, mUID), _ Common.MP("@ProjID", SqlDbType.VarChar, 40, mID), _ Common.MP("@StatusID", SqlDbType.Int, 8, mStatusID), _ Common.MP("@Comments", SqlDbType.NVarChar, 4000, mStatusComments), _ Common.MP("@PCTComp", SqlDbType.Int, 4, 0), _ Common.MP("@Type", Common.TDSqlDbType.TinyInt, 1, EntryType)) Here's the strangest part. When I debug the code, if I type "test test" (without the quotes) into the comments text box, then click the save button and use the immediate window to view the variable values as I step through, here is what I get: ?txtComments.Text "test test" ?txtComments.Text.Trim "test test" ?txtComments.Text(4) " "c ?txtComments.Text.Trim()(4) " "c Anyone have a clue as to what's going on here?

  • Character set issues with Oracle Gateways, SQL Server, and Application Express

    - by Brian Deterling
    I am migrating data from a Oracle on VMS that accesses data on SQL Server using heterogeneous services (over ODBC) to Oracle on AIX accessing the SQL Server via Oracle Gateways (dg4msql). The Oracle VMS database used the WE8ISO8859P1 character set. The AIX database uses WE8MSWIN1252. The SQL Server database uses "Latin1-General, case-insensitive, accent-sensitive, kanatype-insensitive, width-insensitive for Unicode Data, SQL Server Sort Order 52 on Code Page 1252 for non-Unicode Data" according to sp_helpsort. The SQL Server databases uses nchar/nvarchar or all string columns. In Application Express, extra characters are appearing in some cases, for example 123 shows up as %001%002%003. In sqlplus, things look ok but if I use Oracle functions like initcap, I see what appear as spaces between each letter of a string when I query the sql server database (using a database link). This did not occur under the old configuration. I'm assuming the issue is that an nchar has extra bytes in it and the character set in Oracle can't convert it. It appears that the ODBC solution didn't support nchars so must have just cast them back to char and they showed up ok. I only need to view the sql server data so I'm open to any solution such as casting, but I haven't found anything that works. Any ideas on how to deal with this? Should I be using a different character set in Oracle and if so, does that apply to all schemas since I only care about one of them.

  • Using Unicode in fancyvrb’s VerbatimOut

    - by Konrad Rudolph
    Problem VerbatimOut from the “fancyvrb” package doesn’t play nicely with UTF-8 characters. Minimal working example: \documentclass{minimal} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{fancyvrb} \begin{document} \begin{VerbatimOut}{\jobname.test} é \end{VerbatimOut} \input{\jobname.test} \end{document} Error message When compiled using pdflatex mini, this gives the error File ended while scanning use of \UTFviii@three@octets. A different error occurs when the sole occurrence of é above is replaced by something else, e.g. é */: Package inputenc Error: Unicode char \u8:### not set up for use with LaTeX. – indicating that in this case, LaTeX succeeds in reading a multi-byte UTF-8 character, but not knowing what to do with it (i.e. it’s the wrong character). In fact, when I open the produced .test file manually, it contains the character é, but in Latin-1 encoding! Proof: when I open the files in a hex editor, I get the following: Original file: C3 A9 (corresponds to LATIN SMALL LETTER E WITH ACUTE in UTF-8) Written file: E9 (corresponds to é in Latin-1) Question How to set VerbatimOut up correctly? filecontents* (from “filecontents”) shows that it can work. Unfortunately, I don’t understand either code so I cannot fix fancyvrb’s code by replicating the logic from filecontents manually. I also cannot use filecontents* instead of VerbatimOut because the former doesn’t work within a \newenvironment, while the latter does. (Oh, by the way: vanilla Verbatim instead of VerbatimOut also works as expected. The error seems to occur when writing the file, not when reading the verbatim input)

  • 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.

  • Reading binary data from serial port using Dejan TComport Delphi component

    - by johnma
    Apologies for this question but I am a bit of a noob with Delphi. I am using Dejan TComport component to get data from a serial port. A box of equipment connected to the port sends about 100 bytes of binary data to the serial port. What I want to do is extract the bytes as numerical values into an array so that I can perform calculations on them. TComport has a method Read(buffer,Count) which reads DATA from input buffer. function Read(var Buffer; Count: Integer): Integer; The help says the Buffer variable must be large enough to hold Count bytes but does not provide any example of how to use this function. I can see that the Count variable holds the number of bytes received but I can't find a way to access the bytes in Buffer. TComport also has a methord Readstr which reads data from input buffer into a STRING variable. function ReadStr(var Str: String; Count: Integer): Integer; Again the Count variable shows the number of bytes received and I can use Memo1.Text:=str to display some information but obviously Memo1 has problems displaying the control characters. I have tried various ways to try and extract the byte data from Str but so far without success. I am sure it must be easy. Here's hoping.

  • Encoding a email address that can be used as part of a URL in codeigniter

    - by freedayum
    Is there a way to encode a email address that can be used as a part of a url in codeigniter?. I need to decode back the email address from the url. What I am trying to do is just a -forgotten password recovery- thing. I send a confirmation link to the user's email address, the link needs to be like ../encodedEmail/forgottenPasswordCode (with the forgottenPasswordCode updated in the db for the user with the submitted email). When the user visits that link, I decode the email(if the email - forgottenPasswordCode pair is in the table), i allow them to reset their password (and i reset forgottenPasswordCode back to null). I could just do a loop -checking the table with a select query- (or) -set that forgottenPasswordCode column unique, so i keep generating on a insert failure(would that be a lot faster ?)- until I generate a forgottenPasswordCode that doesn't already exist in the table. But the guy I do this for would not accept it this way:). He wants the checking be done with the user's email, he thinks its much faster. I am working with codeigniter, I used its encode() function, it seems to produce characters like '-slashes-' at times that breaks the encoded-email-string. Any other ideas?

  • 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.

  • How to remove old indexed URLs from Google?

    - by Gok Demir
    I used Cs-cart for a site. Default installation SEO is not suitable for Turkish accented characters such as "ö" which maps to automatically "ae". Then I modified the php code and now it substitutes "ö" with "o" and "s"-"s" etc. Also I changed a category name to a better one. My problem is, google indexed both previous versions and new versions. Previous wrong urls gives 404 error. I used sitemap addon and send it to google and sitemap does not include wrong urls. However these old urls are still indexed on google. What can I do to remove them. For example http://www.google.com.tr/search?q=%C3%A7ak%C4%B1l+ta%C5%9Flar%C4%B1ndan+babil+site:eeski.com&hl=tr&client=firefox-a&hs=Z31&rls=com.ubuntu:en-US:official&filter=0 gives two top results old wrong url leads to 404: http://www.eeski.com/kitap-dergi/bilim-ve-teknik/cakl-talarndan-babil-kulesine-rakamlarn-evrensel-tarihi-ii.html right current url: http://www.eeski.com/kitap/bilim-ve-teknik/cakil-taslarindan-babil-kulesine-rakamlarin-evrensel-tarihi-ii.html What could I make google only index current urls stated on sitemap?

  • BindAttribute, Exclude nested properties for complex types

    - by David Board
    I have a 'Stream' model: public class Stream { public int ID { get; set; } [Required] [StringLength(50, ErrorMessage = "Stream name cannot be longer than 50 characters.")] public string Name { get; set; } [Required] [DataType(DataType.Url)] public string URL { get; set; } [Required] [Display(Name="Service")] public int ServiceID { get; set; } public virtual Service Service { get; set; } public virtual ICollection<Event> Events { get; set; } public virtual ICollection<Monitor> Monitors { get; set; } public virtual ICollection<AlertRule> AlertRules { get; set; } } For the 'create' view for this model, I have made a view model to pass some additional information to the view: public class StreamCreateVM { public Stream Stream { get; set; } public SelectList ServicesList { get; set; } public int SelectedService { get; set; } } Here is my create post action: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create([Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] StreamCreateVM viewModel) { if (ModelState.IsValid) { db.Streams.Add(viewModel.Stream); db.SaveChanges(); return RedirectToAction("Index", "Service", new { id = viewModel.Stream.ServiceID }); } return View(viewModel); } Now, this all works, apart from the [Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] bit. I can't seem to Include or Exclude properties within a nested object.

  • jquery insertAfter or append question

    - by user271619
    I am playing around with validating form inputs. For now I'm simply having fun with displaying a message after the input. I'm using the after() method to display simple text, and when I purposely make a mistake in the box I display the message perfectly. However, if I purposely make a mistake again, it immediately adds the same message after the first error message. Is there a method that replaces the original? I didn't want to try to add some more code to look for that original error message, delete it, and then insert the same message again. I will if I have to, but I thought I'd ask first. Here's my code: <script language="javascript" type="text/javascript"> $(document).ready(function(){ $("form#testform").submit(function(){ if($("#fieldname1").val().length < 5){ $("#fieldone").after("<div>not enough characters</div>"); } });return false; }); </script> <form id="testform" method="post"> <table> <tr> <td style="width:100px;">Field One:</td> <td><input type="text" name="fieldname1" id="fieldname1" /></td> </tr> <tr> <td>&nbsp;</td> <td><input type="submit" name="Submit" value="Submit" /></td> </tr> </table> </form>

  • String.Empty in strings, need some explanation if possible :)

    - by Pabuc
    Hello all, 2 days ago, there was a question related to string.LastIndexOf(String.Empty) returning the last index of string. So I thought that; a string can always contain string.empty between characters like: "testing" == "t" + String.Empty + "e" + String.Empty +"sting" + String.Empty; After this, I wanted to test if String.IndexOf(String.Empty) was returning 0 because since String.Empty can be between any char in a string, that would be what I expect it to return and I wasn't wrong. string testString = "testing"; int index = testString.LastIndexOf(string.Empty); // index is 6 index = testString.IndexOf(string.Empty); // index is 0 It actually returned 0. I started to think that if I could split a string with String.Empty, I would get at least 2 string and those would be String.Empty and rest of the string since String.IndexOf(String.Empty) returned 0 and String.LastIndexOf(String.Empty) returned length of the string.. Here is what I coded: string emptyString = string.Empty; char[] emptyStringCharArr = emptyString.ToCharArray(); string myDummyString = "abcdefg"; string[] result = myDummyString.Split(emptyStringCharArr); The problem here is, I can't obviously convert String.Empty to char[] and result in an empty string[]. I would really love to see the result of this operation and the reason behind this. So my questions are: Is there any way to split a string with String.Empty? If it is not possible but in an absolute world which it would be possible, would it return an array full of chars like [0] = "t" [1] = "e" [2] = "s" and so on or would it just return the complete string? Which would make more sense and why? Thank you for your time.

  • How do I escape a LIKE clause using NHibernate Criteria?

    - by Jon Seigel
    The code we're using is straight-forward in this part of the search query: myCriteria.Add( Expression.InsensitiveLike("Code", itemCode, MatchMode.Anywhere)); and this works fine in a production environment. The issue is that one of our clients has item codes that contain % symbols which this query needs to match. The resulting SQL output from this code is similar to: SELECT ... FROM ItemCodes WHERE ... AND Code LIKE '%ItemWith%Symbol%' which clearly explains why they're getting some odd results in item searches. Is there a way to enable escaping using the programmatic Criteria methods? Addendum: We're using a slightly old version of NHibernate, 2.1.0.4000 (current as of writing is 2.1.2.4853), but I checked the release notes, and there was no mention of a fix for this. I didn't find any open issue in their bugtracker either. We're using SQL Server, so I can escape the special characters (%, _, [, and ^) in code really easily, but the point of us using NHibernate was to make our application database-engine-independent as much as possible. Neither Restrictions.InsensitiveLike() nor HqlQueryUtil.GetLikeExpr() escape their inputs, and removing the MatchMode parameter makes no difference as far as escaping goes.

  • UTF-8 character encoding battles json_encode()

    - by Dave Jarvis
    Quest I am looking to fetch rows that have accented characters. The encoding for the column (NAME) is latin1_swedish_ci. The Code The following query returns Abord â Plouffe using phpMyAdmin: SELECT C.NAME FROM CITY C WHERE C.REGION_ID=10 AND C.NAME_LOWERCASE LIKE '%abor%' ORDER BY C.NAME LIMIT 30 The following displays expected values (function is called db_fetch_all( $result )): while( $row = mysql_fetch_assoc( $result ) ) { foreach( $row as $value ) { echo $value . " "; $value = utf8_encode( $value ); echo $value . " "; } $r[] = $row; } The displayed values: 5482 5482 Abord â Plouffe Abord â Plouffe The array is then encoded using json_encode: $rows = db_fetch_all( $result ); echo json_encode( $rows ); Problem The web browser receives the following value: {"ID":"5482","NAME":null} Instead of: {"ID":"5482","NAME":"Abord â Plouffe"} (Or the encoded equivalent.) Question The documentation states that json_encode() works on UTF-8. I can see the values being encoded from LATIN1 to UTF-8. After the call to json_encode(), however, the value becomes null. How do I make json_encode() encode the UTF-8 values properly? One possible solution is to use the Zend Framework, but I'd rather not if it can be avoided.

  • MVC2 and jquery.validate.js

    - by Will I Am
    I am experiencing some confusion with jquery.validate.js First of all, what is MicrosoftMvcJqueryValidation.js. It is referenced in snippets on the web but appears to have dissapeared from the RTM MVC2 and is now in futures. Do I need it? The reason I'm asking is that I'm trying to use the validator with MVC and I can't get it to work. I defined my JS as: $(document).ready(function () { $("#myForm").validate({ rules: { f_fullname: { required: true }, f_email: { required: true, email: true }, f_email_c: { equalTo: "#f_email" }, f_password: { required: true, minlength: 6 }, f_password_c: { equalTo: "#f_password" } }, messages: { f_fullname: { required: "* required" }, f_email: { required: "* required", email: "* not a valid email address" }, f_email_c: { equalTo: "* does not match the other email" }, f_password: { required: "* required", minlength: "password must be at least 6 characters long" }, f_password_c: { equalTo: "* does not match the other email" } } }); }); and my form on the view: <% using (Html.BeginForm("CreateNew", "Account", FormMethod.Post, new { id = "myForm" })) { %> <fieldset> <label for="f_fullname">name:</label><input id="f_fullname"/> <label for="f_email"><input id="f_email"/> ...etc... <input type="submit" value="Create" id="f_submit"/> </fieldset> <% } %> and the validation method gets called on .ready() with no errors in firebug. however when I submit the form, nothing gets validated and the form gets submitted. If I create a submitHandler() it gets called, but the plugin doesn't detect any validation errors (.valid() == true) What am I missing?

  • Ascii Bytes Array To Int32 or Double

    - by Michael Covelli
    I'm re-writing alibrary with a mandate to make it totally allocation free. The goal is to have 0 collections after the app's startup phase is done. Previously, there were a lot of calls like this: Int32 foo = Int32.Parse(ASCIIEncoding.ASCII.GetString(bytes, start, length)); Which I believe is allocating a string. I couldn't find a C# library function that would do the same thing automatically. I looked at the BitConverter class, but it looks like that is only if your Int32 is encoded with the actual bytes that represent it. Here, I have an array of bytes representing Ascii characters that represent an Int32. Here's what I did public static Int32 AsciiBytesToInt32(byte[] bytes, int start, int length) { Int32 Temp = 0; Int32 Result = 0; Int32 j = 1; for (int i = start + length - 1; i >= start; i--) { Temp = ((Int32)bytes[i]) - 48; if (Temp < 0 || Temp > 9) { throw new Exception("Bytes In AsciiBytesToInt32 Are Not An Int32"); } Result += Temp * j; j *= 10; } return Result; } Does anyone know of a C# library function that already does this in a more optimal way? Or an improvement to make the above run faster (its going to be called millions of times during the day probably). Thanks!

  • XML Schema to restrict one field based on another

    - by Kevin Albrecht
    I have the following schema, which I use to ensure that a person's PhoneNumber and PhoneNumberType (Home, Work, etc.) is not longer than 10 characters. However, I want to improve this schema so that PhoneNumberType is not required if a PhoneNumber is not provided, but is required if the PhoneNumber is provided.

I have this simple code snippet that draws a letter "a" inside the circle: ''' Created on May 8, 2010 @author: mrios ''' import cairo, math WIDTH, HEIGHT = 1000, 1000 #surface = cairo.PDFSurface ("/Users/mrios/Desktop/exampleplaces.pdf", WIDTH, HEIGHT) surface = cairo.ImageSurface (cairo.FORMAT_ARGB32, WIDTH, HEIGHT) ctx = cairo.Context (surface) ctx.scale (WIDTH/1.0, HEIGHT/1.0) # Normalizing the canvas ctx.rectangle(0, 0, 1, 1) # Rectangle(x0, y0, x1, y1) ctx.set_source_rgb(255,255,255) ctx.fill() ctx.arc(0.5, 0.5, .4, 0, 2*math.pi) ctx.set_source_rgb(0,0,0) ctx.set_line_width(0.03) ctx.stroke() ctx.arc(0.5, 0.5, .4, 0, 2*math.pi) ctx.set_source_rgb(0,0,0) ctx.set_line_width(0.01) ctx.set_source_rgb(255,0,255) ctx.fill() ctx.set_source_rgb(0,0,0) ctx.select_font_face("Georgia", cairo.FONT_SLANT_NORMAL, cairo.FONT_WEIGHT_BOLD) ctx.set_font_size(1.0) x_bearing, y_bearing, width, height = ctx.text_extents("a")[:4] print ctx.text_extents("a")[:4] ctx.move_to(0.5 - width / 2 - x_bearing, 0.5 - height / 2 - y_bearing) ctx.show_text("a") surface.write_to_png ("/Users/mrios/Desktop/node.png") # Output to PNG The problem is that my labels have variable amount of characters (with a limit of 20) and I need to set the size of the font dynamically. It must fit inside the circle, no matter the size of the circle nor the size of the label. Also, every label has one line of text, no spaces, no line breaks. Any suggestion?

  • MySQL Unique hash insertion

    - by Jesse
    So, imagine a mysql table with a few simple columns, an auto increment, and a hash (varchar, UNIQUE). Is it possible to give mysql a query that will add a column, and generate a unique hash without multiple queries? Currently, the only way I can think of to achieve this is with a while, which I worry would become more and more processor intensive the more entries were in the db. Here's some pseudo-php, obviously untested, but gets the general idea across: while(!query("INSERT INTO table (hash) VALUES (".generate_hash().");")){ //found conflict, try again. } In the above example, the hash column would be UNIQUE, and so the query would fail. The problem is, say there's 500,000 entries in the db and I'm working off of a base36 hash generator, with 4 characters. The likelyhood of a conflict would be almost 1 in 3, and I definitely can't be running 160,000 queries. In fact, any more than 5 I would consider unacceptable. So, can I do this with pure SQL? I would need to generate a base62, 6 char string (like: "j8Du7X", chars a-z, A-Z, and 0-9), and either update the last_insert_id with it, or even better, generate it during the insert. I can handle basic CRUD with MySQL, but even JOINs are a little outside of my MySQL comfort zone, so excuse my ignorance if this is cake. Any ideas? I'd prefer to use either pure MySQL or PHP & MySQL, but hell, if another language can get this done cleanly, I'd build a script and AJAX it too. Thanks!

  • ASP.NET required field validator firing on focus in Firefox

    - by ren33
    I have 2 asp.net textboxes in an update panel. Both textbox controls have some javascript attached to autotab to the next field and to allow only numeric input. When I enter some data into the first field and press enter, focus shifts to the next field and the requiredfieldvalidator of the second field displays its "* required" error message, even though I've just entered the field. This is only happening in Firefox. How can I prevent the validator from firing when I first enter the textbox? edit Here's the code: <asp:TextBox ID="add_ISBN" runat="server" Columns="14" MaxLength="17" CssClass="focus" /> <asp:TextBox ID="add_Qty" runat="server" Columns="4" MaxLength="4" /> <asp:RequiredFieldValidator ID="rfvQty" ControlToValidate="add_Qty" ErrorMessage="* required" ForeColor="Red" Display="Dynamic" EnableClientScript="true" ValidationGroup="Add" runat="server" /> In the codebehind: add_ISBN.Attributes.Add("onkeydown", "return isbnCheck(event, '" & add_Qty.ClientID & "')") And the javascript: function isbnCheck(e, id) { e = e || window.event; var key = e.which || e.keyCode if (validIsbnChars.indexOf(parseInt(key, 10)) >= 0) { return true; } else { if (key == 13) { var nextfield = document.getElementById(id); if (nextfield) nextfield.focus(); return false; } if (e.preventDefault) e.preventDefault(); e.returnValue = false; return false; } } The javascript allows only a valid subset of characters, and if the user presses enter, sets focus to the next field.

  • Print raw data to a thermal-printer using .NET

    - by blauesocke
    I'm trying to print out raw ascii data to a thermal printer. I do this by using this code example: http://support.microsoft.com/kb/322091 but my printer prints always only one character and this not until I press the form feed button. If I print something with notepad the printer will do a form feed automatically but without printing any text. The printer is connected via usb over a lpt2usb adapter and Windows 7 uses the "Generic - Generic / Text Only" driver. Anyone knows what is going wrong? How is it possible to print some words and do some form feeds? Are there some control characters I have to send? And if yes: How do I send them? Edit 14.04.2010 21:51 My code (C#) looks like this: PrinterSettings s = new PrinterSettings(); s.PrinterName = "Generic / Text Only"; RawPrinterHelper.SendStringToPrinter(s.PrinterName, "Test"); This code will return a "T" after I pressed the form feed button (This litte black button here: swissmania.ch/images/935-151.jpg - sorry, not enough reputation for two hyperlinks) Edit 15.04.2010 16:56 I'm using now the code form here: c-sharpcorner.com/UploadFile/johnodonell/PrintingDirectlytothePrinter11222005001207AM/PrintingDirectlytothePrinter.aspx I modified it a bit that I can use the following code: byte[] toSend; // 10 = line feed // 13 carriage return/form feed toSend = new byte[1] { 13 }; PrintDirect.WritePrinter(lhPrinter, toSend, toSend.Length, ref pcWritten); Running this code has the same effekt like pressing the form feed button, it works fine! But code like this still does not work: byte[] toSend; // 10 = line feed // 13 carriage return/form feed toSend = new byte[2] { 66, 67 }; PrintDirect.WritePrinter(lhPrinter, toSend, toSend.Length, ref pcWritten); This will print out just a "B" but I expect "BC" and after running any code I have to reconnect the USB cable to make it work agian. Any ideas?
