• Annoying IE7 problem.

  - by Yo-L

  I am styling a Wordpress theme but has run into problem with IE7. The first word("it") inside the paragraph/strong tag ends up to the left of the img tag when I want it BELOW the image. My problem is that the only element I can change CSS properties here is the div, since the code inside is posted with a WYSIWYG by an blog author. Is there anyway i can fix this problem? I have tried lots of different settings and every other browser FF safari IE8 renders the text below the image. <div style="width: 430px;"> <h1>It is hard getting it right in IE7!</h1> <p> <img class="aligncenter size-full wp-image-4333" src="http://xxx.xxx.xx/files/2010/03/xxx.jpg" alt="xxx" style="width: 430px; height: 600px" /> <strong>It is hard</strong> getting it right in IE7! </p> </div>

• Use of clone() and appendTo() with draggable - unexpected results with dragging

  - by Matt Gutting

  I'm constructing a UI for a doctor scheduling app. We have several doctors, each of whom can go in one of several locations on a scheduled day (M - F). I have the main day/location grid (table) in the center of the screen. At the left is a table for the doctor names. On loading, each table cell contains a span (outlined) with the doctor name. The doctor name can go in one slot for each day. I didn't want to just put 5 copies of the doctor name, because the doctor might not be available all 5 days of the week. The idea was: Drag the span and drop into the calendar table. On the drag "start" event, clone the span and append it to the table cell. Now there is another span ready to be dropped into the calendar table. One line of code does the work: $(ui.helper).clone(true).prependTo(ui.helper.parent()); This works. But when I move the cloned span, the original one moves in sync - preserving the spatial relationships as I move the clone around (no doubt there's a "position:relative;left=XX;top=YY" inserted somewhere). I'm sure there's a way to do what I'm thinking of, while keeping the two spans independent. But I'm not thinking of one. Does anyone have an idea? Thanks! Matt I posted this identical question to the jQuery forum as well.

• What does this script do? Is it malicious?

  - by ramdaz

  This script was added to a defaced web page of a client web site running PHP. I have no clue what this script can do, and do not know whether this is really malicious. Can someone advise.

• int considered harmful?

  - by Chris Becke

  Working on code meant to be portable between Win32 and Win64 and Cocoa, I am really struggling to get to grips with what the @#$% the various standards committees involved over the past decades were thinking when they first came up with, and then perpetuated, the crime against humanity that is the C native typeset - char, short, int and long. On the one hand, as a old-school c++ programmer, there are few statements that were as elegant and/or as simple as for(int i=0; i<some_max; i++) but now, it seems that, in the general case, this code can never be correct. Oh sure, given a particular version of MSVC or GCC, with specific targets, the size of 'int' can be safely assumed. But, in the case of writing very generic c/c++ code that might one day be used on 16 bit hardware, or 128, or just be exposed to a particularly weirdly setup 32/64 bit compiler, how does use int in c++ code in a way that the resulting program would have predictable behavior in any and all possible c++ compilers that implemented c++ according to spec. To resolve these unpredictabilities, C99 and C++98 introduced size_t, uintptr_t, ptrdiff_t, int8_t, int16_t, int32_t, int16_t and so on. Which leaves me thinking that a raw int, anywhere in pure c++ code, should really be considered harmful, as there is some (completely c++xx conforming) compiler, thats going to produce an unexpected or incorrect result with it. (and probably be a attack vector as well)

• ASP.NET membership db using integrated security problem

  - by rem

  I published ASP.NET MVC web site to a server on a virtual machine (Hyper-V). SQL Server Express installed on the same server. The problem is that ASP.Net Membership system doesn't work in integrated mode. When Web.config file contains records as follows: <connectionStrings> <remove name="LocalSqlServer" /> <add name="MyDBConnectionString" connectionString="data source=vm-1\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI;" providerName="System.Data.SqlClient"/> </connectionStrings> I get an error when trying to register and login to the site. If I change connection string this way: <connectionStrings> <remove name="LocalSqlServer" /> <add name="MyDBConnectionString" connectionString="data source=vm-1\SQLEXPRESS;Initial Catalog=testdb;User ID=XX;Password=XXXXXXX;" providerName="System.Data.SqlClient"/> </connectionStrings> I could register and login without any problem. What could cause the problem with using ASP.NET membership database in integrated security mode?

• why does this boost::spirit::qi rule not work?

  I have a grammar that defines the following rules: constantValue = qi::token(ID_FLOAT) | qi::token(ID_INTEGER); postfixExpression = primaryExpression | (postfixExpression >> qi::token(ID_OPENBRACKET) >> qi::token(ID_INTEGER) >> qi::token(ID_CLOSEBRACKET)) | (postfixExpression >> qi::token(ID_DOT) >> qi::token(ID_IDENTIFIER)); primaryExpression = qi::token(ID_IDENTIFIER) | constantValue | (qi::token(ID_OPENPAREN) >> primaryExpression >> qi::token(ID_CLOSEPAREN)); ges = postfixExpression >> qi::eoi; and I want it to match the following strings: test[1] testident.ident and it should not match test[1.2] testident.5 but it fails to match the first 2 strings.

• how to find the last instance of a setting in a config file

  - by Glenn Kelley

  I am trying to figure out how to find the last entry of a string in multiple config files across a server. Each of the strings will be in the /home/***usernamewouldbehere/public_html/typo3conf/localconf.php file In short - the last entry in the config files will point to the database server the application is utilizing - and we need to know which accounts point to which db server. While I can run something like this - grep "$_db_host" /home/*/public_html/conf/localconf.php It does not really help much because it gives us way to much information ... and not what we really need. What i really need to know is the last entry of this string $_db_host = 'xx'; and to sort them out in an export file Since the config files may have multiple entries (example below) $_db_host = 'localhost'; $_db_host = '10.0.1.234'; It would be great to list in a file all of those that have the entry for 'localhost' and then list all of those that have the entry for '10.0.1.234' (or whichever server there may be there) but even if I need to do that manually that would be great. I am not sure how to get to it using Awk - ... and really stuck What I am hoping for is something that would be piped as follows db_host = localhost /home/username1/www/conf/localconf.php db_host = localhost / home/username2/public_html/conf/localconf.php db_host= '10.1.2.23' /home/username55/public_html/conf/localconf.php hoping that helps you help me :-)

• Can't send smtp email from network using C#, asp.net website

  - by Kaysar

  Hi, I have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network. But, problem is when I try this code from my work place, it does not work. Shows error: "unable to connect to the remote server" From a different machine in the same network: "A socket operation was attempted to an unreachable network 209.xxx.xx.52:25" I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail]. Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received. Please note that, the code was tested from development environment, visual studio 2005 and 2008. Any suggestion will be much appreciated. Thanks in advance try { MailMessage mail_message = new MailMessage("[email protected]", txtToEmail.Text, txtSubject.Text, txtBody.Text); SmtpClient mail_client = new SmtpClient("SMTP.y7mail.com"); NetworkCredential Authentic = new NetworkCredential("[email protected]", "xxxxx"); mail_client.UseDefaultCredentials = true; mail_client.Credentials = Authentic; mail_message.IsBodyHtml = true; mail_message.Priority = MailPriority.High; try { mail_client.Send(mail_message); lblStatus.Text = "Mail Sent Successfully"; } catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.Message); lblStatus.Text = "Mail Sending Failed\r\n" + ex.Message; } } catch (Exception ex) { lblStatus.Text = "Mail Sending Failed\r\n" + ex.Message; }

• Regular expression for dividing country calling codes

  - by RickiG

  Hi I have a list of calling codes for all countries(the phone number prefixes), I would like to split them up in the country name and the actual code so I can put then into an xml. I have tried back and forth but can not get a regexp going that takes all cases into account. I think it is fairly simple for someone with a bit of experience. The codes have these formats: Afghanistan 93 Anguilla 1 264 Antarctica 6721 Antigua and Barbuda 1 268 Bosnia and Herzegovina 387 Canada 1 Congo, Republic of the 242 Cote d'Ivoire 225 Ireland (Eire) 353 United States of America 1 There are around 235 of them in total, but these are the regulars and the exceptions. ^[a-zA-Z]\s,'()] for between 1 and X words and then it is [0-9\s]{1,5}$ for the numbers: X XX XXX XXXX X XXX So if I should express it as a sentence it would be: "from beginning of a line, take all characters (1) including space,'() until you encounter digits, then take all of these including space(2) until you encounter a line break." I am using TextMate, and the docs says: TextMate uses the Oniguruma regular expression library by K. Kosako. I would appreciate any help given:) Thank you.

• How to increase PermGen memory for eclipselink StaticWeaveAntTask

  - by rayd09

  We are using Eclipselink and need to weave the code in order for lazy fetching to work property. During the weave process I'm getting the following error: weave: BUILD FAILED java.lang.OutOfMemoryError: PermGen space I have the following tasks within my ant build file: <target name="define_weave_task" description="task definition for EclipseLink static weaving"> <taskdef name="eclipse_weave" classname="org.eclipse.persistence.tools.weaving.jpa.StaticWeaveAntTask"/> </target> <target name="weave" depends="compile,define_weave_task" description="weave eclipselink code into compiled classes"> <eclipse_weave source="${path.classes}" target="${path.classes}"> <classpath refid="compile.classpath"/> </eclipse_weave> </target> It has been working great for a long time. Now that the amount of code to be woven has increased I'm getting the PermGen error. I would like to be able to up the amount of perm space. If I was doing a compile I would be able to up the perm space via a compiler argument such as <compilerarg value="-XX:MaxPermSize=256M"/> but this does not appear to be a valid argument for eclipselink weaving. How can I up the perm space for the weave?

• How to make a increasing numbers after filenames in C?

  - by zaplec

  Hi, I have a little problem. I need to do some little operations on quite many files in one little program. So far I have decided to operate them in a single loop where I just change the number after the name. The files are all named TFxx.txt where xx is increasing number from 1 to 80. So how can I open them all in a single loop one after one? I have tried this: for(i=0; i<=80; i++) { char name[8] = "TF"+i+".txt"; FILE = open(name, r); /* Do something */ } As you can see the second line would be working in python but not in C. I have tried to do similiar running numbering with C to this program, but I haven't found out yet how to do that. The format doesn't need to be as it is on the second line, but I'd like to have some advice of how can I solve this problem. All I need to do is just be able to open many files and do same operations to them.

• Preventing HTML character entities in locale files from getting munged by Rails3 xss protection

  - by Chris S

  We're building an app, our first using Rails 3, and we're having to build I18n in from the outset. Being perfectionists, we want real typography to be used in our views: dashes, curled quotes, ellipses et al. This means in our locales/xx.yml files we have two choices: Use real UTF-8 characters inline. Should work, but hard to type, and scares me due to the amount of software which still does naughty things to unicode. Use HTML character entities (&#8217; &#8212; etc). Easier to type, and probably more compatible with misbehaving software. I'd rather take the second option, however the auto-escaping in Rails 3 makes this problematic, as the ampersands in the YAML get auto-converted into character entities themselves, resulting in 'visible' &8217;s in the browser. Obviously this can be worked around by using raw on strings, i.e.: raw t('views.signup.organisation_details') But we're not happy going down the route of globally raw-ing every time we t something as it leaves us open to making an error and producing an XSS hole. We could selectively raw strings which we know contain character entities, but this would be hard to scale, and just feels wrong - besides, a string which contains an entity in one language may not in another. Any suggestions on a clever rails-y way to fix this? Or are we doomed to crap typography, xss holes, hours of wasted effort or all thre?

• How to return array of C++ objects from a PHP extension

  I need to have my PHP extension return an array of objects, but I can't seem to figure out how to do this. I have a Graph object written in C++. Graph.getNodes() returns a std::map<int, Node*>.

• Why is my user control not instanciated on a postback?

  - by Antoine

  Hi, I'd like to set the trigger of an UpdatePanel to a user control outside the UpdatePanel on the same page . The user control is added at design time, not at runtime. If I statically declare the trigger, I get an error "A control with ID 'xx' cannot be found for the trigger in UpdatePanel". I tried to add the trigger at runtime in Page_Init or Page_Load, but it fails with the user control being null, although it has ViewState enabled. Has someone an idea on how to solve this? Here is the code of the user control: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="ComponentDropDownControl.ascx.cs" Inherits="ComponentDropDownControl" EnableViewState="true" %> <asp:DropDownList ID="ComponentDropDown" runat="server" DataSourceID="ComponentFile" DataTextField="name" DataValueField="name" OnSelectedIndexChanged="ComponentDropDown_SelectedIndexChanged" AutoPostBack="True" EnableTheming="True"> </asp:DropDownList><asp:XmlDataSource ID="ComponentFile" runat="server" DataFile="~/App_Data/Components.xml" XPath="//component"></asp:XmlDataSource> And here it is in the aspx page: <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="create.aspx.cs" Inherits="create" Title="Create task" %> <%@ Register Src="ComponentDropDownControl.ascx" TagName="ComponentDropDownControl" TagPrefix="uc1" %> ... <uc1:ComponentDropDownControl ID="CustomComponentDropDown" runat="server" EnableViewState="true" /> In the Page_Load function of the aspx page, the following lines work at first time, but fail on the first PostBack (line 2, CustomComponentDropDown is null). AsyncPostBackTrigger trigger = new AsyncPostBackTrigger(); trigger.ControlID = CustomComponentDropDown.UniqueID.ToString(); UpdatePanel1.Triggers.Add(trigger);

• (JBoss) Problem with .war project on production, while test works

  - by ikky

  Hello. I have a java project (using Spring mvc) which i have built and deployed on my local computer. It runs on a JBoss application server, and works fine on the local machine. The next step i do, is to copy the deployed project.war from the local machine to the server which has the same development environment as the local machine. I stop the JBoss server, delete the cache, and run the JBoss server again. When i now try to run one of the pages(xx.xxx.xxx:8080/webservice/test.htm), i get this exception: exception org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:583) root cause java.lang.NullPointerException com.project.db.DBCustomer.isCredentialsCorrect(DBCustomer.java:44) com.project.CreateHController.handleRequest(CreateHController.java:60) org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter.handle(SimpleControllerHandlerAdapter.java:48) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:875) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:807) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:501) javax.servlet.http.HttpServlet.service(HttpServlet.java:697) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:75) It seems like none of my classes are reachable. Does anyone have any idea of what is wrong? btw: as i said, the project works fine on the local machine.

• Calling a jQuery method at declaration time, and then onEvent

  - by cesarsalazar

  I've been writing JS (mainly jQuery) for quite a few months now, but today I decided to make my first abstraction as a jQuery method. I already have working code but I feel/know that I'm not doing it the right way, so I come here for some enlightenment. Note: Please do not reply that there's already something out there that does the trick as I already know that. My interest in this matter is rather educational. What my code is intended to do (and does): Limit the characters of a textfield and change the color of the counter when the user is approaching the end. And here's what I have: $(function(){ $('#bio textarea').keyup(function(){ $(this).char_length_validation({ maxlength: 500, warning: 50, validationSelector: '#bio .note' }) }) $('#bio textarea').trigger('keyup'); }) jQuery.fn.char_length_validation = function(opts){ chars_left = opts.maxlength - this.val().length; if(chars_left >= 0){ $(opts.validationSelector + ' .value').text(chars_left); if(chars_left < opts.warning){ $(opts.validationSelector).addClass('invalid'); } else{ $(opts.validationSelector).removeClass('invalid'); } } else{ this.value = this.value.substring(0, opts.maxlength); } } In the HTML: <div id="bio"> <textarea>Some text</textarea> <p class="note> <span class="value">XX</span> <span> characters left</span> </p> </div> Particularly I feel really uncomfortable binding the event each on each keyup instead of binding once and calling a method later. Also, (and hence the title) I need to call the method initially (when the page renders) and then every time the user inputs a character. Thanks in advance for your time :)

• Splitting 25mb .txt file into smaller files using text delimiter

  - by user574141

  Regards, SO I am new to python and Perl. I have been trying to solve a simple problem and getting tied in knots with syntax. I hope someone has the time and patience to help. I have a 25mb file in ".txt" format which contains news-wire articles going back to 1970. Each news story is concatenated to the next, with only the "Copyright" statement to delimit. Each news story starts with "Item XX of XXX DOCUMENTS". There are certain metadata that are repeated throughout, I will use these for tagging later on. I wish to split this 25mb file into separate .txt files, each containing one news story (i.e. the text between "DOCUMENTS" and "Copyright", saving each with a different name (obviously). I am trying to 1 ) open the file... 2) iterate over lines in the file checking for the eof delimiter, and if it is not present writing the line to a list 3)write that list to a seperate small file. I'm having big problems with changing filenames using the counter, and how do I make Python start from where I left off, is the "seek" function appropriate? so far I have been trying this approach, completely unsuccessfully: myfile = open ("myfile.txt", 'r') filenumber = 0 for line in myfile.readline(): filenumber += 1 w=0 while myfile.readline() != '\s+DOCUMENTS\s*\n' ### read my line into a list mysmallfile()['w'] = [myfile.readline()] w += 1 output = open('C:\\Users\\dunner7\\Documents\###how do I change the filename each iteration???', 'w') output.writelines(mysmallfile) ###go back to start. Thank you for your time and patience. RD

• jQuery form zip code to state function

  - by Dakota R.

  I'm trying to convert a preexisting javascript function into a jQuery function. The function comes from http://javascript.internet.com/forms/zip-to-state.html and aims to convert a user-entered zip code into a state. I'm using jQuery 1.3.2, with all the necessary plugins, but I'm not very familiar with jQuery syntax and how to convert this from plain ol' Javascript syntax. The setState function takes two parameters, the zip code element and the state element, so I'm trying to do something like this: $('$zip_code').change( function () { setState($(this), $('#state')); }); Any thoughts on this syntax? Thanks, Dakota function getState(zip) { if ((parseInt(zipString.substr(zip / 4, 1), 16) & Math.pow(2, zip % 4)) && (zip.length == 5)) for (var i = 0; i < stateRange.length; i += 7) if (zip <= 1 * stateRange.substr(i, 5)) return stateRange.substr(i + 5, 2); return null; } function setState(txtZip, optionBox) { if (txtZip.value.length != 5 || isNaN(txtZip.value / 4)) { optionBox.options[0].selected = true; alert("Please enter a 5 digit, numeric zip code."); return; } var state = getState(txtZip.value); for (var i = 0; i < optionBox.options.length; i++) if (optionBox.options[i].value == state) return optionBox.options[i].selected = true; for (var i = 0; i < optionBox.options.length; i++) if (optionBox.options[i].value == "XX") return optionBox.options[i].selected = true; }

• Web page for IPhone - Large fonts instead of scrolling?

  - by chris_l

  I'm planning the layout of my web page, which should also be usable on the IPhone. I don't really have much experience with the IPhone yet - I just installed the IPhone Simulator on my Mac. The page's contents are flexible, so I think it would be better to use this flexibility to avoid that the user has to scroll around the entire page. Especially I have A header and a sidebar that will be used all the time to perform several actions. A main content area with a number of elements (e.g. images). The UI would stay usable pretty well, if the number of elements shown at one time is reduced for a small screen (e.g. by JavaScript). It would also be okay to make the main content area scrollable (as opposed to the entire page). The problem: If I simply display the page on the IPhone, it uses an extremely small font size, so that users must zoom in first, and then scroll around - so that they can't see the header and sidebar all the time. What's the best way to deal with this situation? Just leave it this way (very small fonts), because users expect that behaviour on the IPhone? Increase the font size (by specifying it in em or px or with xx-large, or what would be the best way?), if I detect - somehow - that it's being displayed on the IPhone. Or is there some way to restrict the viewport size to the screen size, and make it zoom in automatically? I think that would be the easiest solution in my case. Or ...?

• unresolved token/symbol in MC++ wrapper class calling native code

  - by rediVider

  I'm new to MC++ and have basically no idea what's going on yet. In trying to get this working i've determined many things that don't work, i'm just looking for one of the ways that will work. I have a mc++ class as follows that seems to have to be a "ref" class to allow me to see any methods/properties. public ref class EmCeePlusPlus { static void Open(void) { Testor* t = new Testor(); Testor::Open(); }; }; extern public class Testor { public: Testor() { }; static void Open(void) { int x = 3; int xx = cli_lock(x); }; }; Now, the only reason i created the class Testor, and moved the call to cli_open to it, is because i was getting a unresolved external symbol if i put the same call in the ref class. In this current code, however, I get an uresolved token error and unresolved symbol error ONLY if i have the call to Testor::Open(). If that line is commented then it compiles fine. As it is I get the errors below. cli_lock() is native code that is able to be called externally by other native DLLs with not problems. Any ideas where i should be looking? error LNK2028: unresolved token (0A000056) "extern "C" int __cdecl cli_lock(int)" (?cli_lock@@$$J0YAHH@Z) referenced in function "public: static void __cdecl Giga::Testor::Open(void)" (?Open@Testor@Giga@@$$FSAXXZ) error LNK2019: unresolved external symbol "extern "C" int __cdecl cli_lock(int)" (?cli_lock@@$$J0YAHH@Z) referenced in function "public: static void __cdecl Giga::Testor::Open(void)" (?Open@Testor@Giga@@$$FSAXXZ)
