• Watir changes highline's "ask" method

  - by grundic

  Hello! I've encoutered some strange functionality, when using Watir and Highline together. Here is simple example: require 'highline/import' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp require 'watir' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp Here is an output: Company? |MySuperCompany| MySuperCompany [Company? ] => Company? Maybe it's a bug? I've also found in documentation for highline, that If @question is set before ask() is called, parameters are ignored and that object (must be a HighLine::Question) is used to drive the process instead. Sorry, I'm not a ruby guru :-(

• Snow Leopard mounted directory changes permissions sporadically

  - by Galen

  I have a smb mounted directory: /Volumes/myshare This was mounted via Finder "Connect to Server..." with smb://myservername/myshare Everything good so far. However, when I try to access the directory via PHP (running under Apache), it fails with permission denied about 10% of the time. By this I mean that repeated accesses to my page sometimes result in a failure. My PHP page looks like: <?php $cmd = "ls -la /Volumes/ 2>&1"; exec($cmd, $execOut, $exitCode); echo "<PRE>EXIT CODE = $exitCode<BR/>"; foreach($execOut as $line) { echo "$line <BR/>"; } echo "</PRE>"; ?> When it succeeds it looks like: EXIT CODE = 0 total 40 drwxrwxrwt@ 4 root admin 136 Jun 14 12:34 . drwxrwxr-t 30 root admin 1088 Jun 4 13:09 .. drwx------ 1 galen staff 16384 Jun 14 09:28 myshare lrwxr-xr-x 1 root admin 1 Jun 11 16:05 galenhd - / When it fails it looks like: EXIT CODE = 1 ls: myshare: Permission denied total 8 drwxrwxrwt@ 4 root admin 136 Jun 14 12:34 . drwxrwxr-t 30 root admin 1088 Jun 4 13:09 .. lrwxr-xr-x 1 root admin 1 Jun 11 16:05 galenhd - / OTHER INFO: I'm working with the PHP (5.3.1), and Apache server that comes out of the box with Snow Leopard. Also, if I write a PHP script that loops and retries the "ls -la.." from the command-line, it doesn't seem to fail. Nothing is changing about the code and/or filesystem between succeeds and fails, so this appears to be a truly intermittent failure. This is driving me crazy. Anyone have any idea what might be going on? Thanks, Galen

• IntelliJ Doesn't Notice Changes in Interface

  - by yar

  [I've decided to give IntelliJ another go (to replace Eclipse), since its Groovy support is supposed to be the best. But back to Java...] I have an Interface that defines a constant public static final int CHANNEL_IN = 1; and about 20 classes in my Module that implement that interface. I've decided that this constant was a bad idea so I did what I do in Eclipse: I deleted the entire line. This should cause the Project tree to light up like a Christmas tree and all classes that implement that interface and use that constant to break. Instead, this is not happening. If I don't actually double-click on the relevant classes -- which I find using grep -- the module even builds correctly (using Build - Make Module). If I double-click on a relevant class, the error is shown both in the Project Tree and in the Editor. I am not able to replicate this behavior in small tests, but in large modules it works (incorrectly) this way. Is there some relevant setting in IntelliJ for this?

• Managing changes in memory-based data format

  - by kamziro

  So I've been using a compact data type in c++, and saving from memory or loading from the file involves just copying the bits of memory in and out. However, the obvious drawback of this is that if you need to add/remove elements on the data, it becomes kind of messy. There's also problems with versioning, suppose you distribute a program which uses version A of the data, and then the next day you make version B of it, and then later on version C. I suppose this can be solved by using something like xml or json. But suppose you can't do that for technical reasons. What is the best way to do this, apart from having to make different if cases etc (which would be pretty ugly, I'd imagine)

• .submit() changes post data

  - by ajbeaven

  I'm posting a form with javascript and it seems to be changing a value that I've entered in. Html: <% using (Html.BeginForm("ChangeTime", "Cart", new { cartItemId = cartItem.CartItemID }, FormMethod.Post, null)) { %> <%= Html.TextBox("startTime")%> <input type="submit" value="Update" /> <% } %> JQuery: <script type="text/javascript"> $('#startTime').change(function() { $(this).parent('form').submit(); }); </script> When I put a time in the textbox (05/05/2010 06:08 am), the form is submitted, however the string as it comes through, is 05/05/2010 - with the time part removed. I see this in fiddler. If get rid of the javascript and click the button above, it goes through how it should. Why is JQuery changing my text?

• How to detect application préference changes.

  - by Raphael Pinto

  I created a Settings.bundle in my app where the user can change some properties like font size. It works. But when I leave my App, and I change my setting, I don't know how I can get notified of the change. For the moment, I create a function call each time a view is loaded that check for app settings. But I wonder if there is an other and proper way to do this.

• Dropdownlists creates postback on key changes in IE

  - by Dofs

  I have created a label and a dropdownlist. The label has the dropdownlist as associated id. If I click on the label and then uses the mouse up or down the dropdownlist creates a postback for each click. This is quite anoying and doesn't happen if you click on the dropdownlist and uses key-up or key-down, or if you uses another browser than IE. Is it possibel to fix this, so you can use key-up and key-down without causing a postback, and first on the enter-key creates the postback (as it does if you click on the dropdownlist and not label)?

• File modified date/time changes when uploaded via FTP

  - by Nate Shoffner

  Hey /g/, FTP/PHP question here. On one of my pages I load .txt files from a directory. Pretty simple. I also display the modified date of the text file using this: date('m/d/Y', filemtime($file)); This works fine on my WAMP server but when I upload the files via FTP, the modified date is changed to when they were uploaded. I'm currently hosting on a free hosting provider (freehostia to be exact). Is there any way to keep the modified date/time from changing when it's uploaded? Or is there perhaps an alternative way to go about this? Any ideas are appreciated.

• ASP.NET: Session.SessionID changes between requests

  - by Seb Nilsson

  Why does the property SessionID on the Session-object in an ASP.NET-page change between requests? I have a page like this: ... <div> SessionID: <%= SessionID %> </div> ... And the output keeps changing every time I hit F5, independent of browser. I've seen this work correctly in other projects.

• HTML form submits and the hostname changes to IP address

  - by Shamik

  I am facing a peculiar problem. The problem is, my webapp is being installed behind a proxy. The request gets submitted to the proxy which forwards the request to the original host that is running the websphere web application. The problem I am facing is, when I access the webapp, its URL looks like the below http://www.myproxy.com Lets say I get a form on this URL, when I submit the form, it is getting submitted to another URL - http://10.1.2.87 Since the URL is changing, application server thinks it is a different session and throws the login page again. The login page comes thru a filter which checks whether user is already authenticated in the session or not. I do not have much knowledge on proxy settings .. where do you think is the problem?

• IE 8 specifying background-color changes element behavior

  - by Mateo

  I have an absolutely positioned div on which I am trying to trigger mouseenter and mouseleave events. In IE8/7 with the background-color of the div left unspecified (so that it defaults to transparent), the mouseenter/leave events are not firing when the cursor crosses the div's boundary, only somewhere in the middle of the div and when the cursor is over any text within the div. When I attempt to debug the problem by adding a background color to the div (e.g. background-color: green), the problem magically goes away. The div's box model is honored perfectly and mouseenter/leave fire as when expected. It's only when the div's background color is left unspecified (or even explicitly set to transparent) that it doesn't behave correctly. Any ideas? Googling for this IE bug/quirk is coming up with nothing.

• How to manage changes to reports in .NET?

  - by Craig Johnston

  If I need to offer the ability to create, view and print reports from a .NET app, I see that there are 2 options: use a reporting component such as Microsoft.Reporting.WinForms.ReportViewer or Crystal Reports which saves a .rpt or similar template file that can be modified as required without having to re-compile the app use System.Drawing.Printing for reporting and store report template data in a database, which keeps things simpler and avoids problems with bulky third party reporting components If I want to be able to modify a report template (which would include layout and data fields) without having to re-compile the app, would the first option above achieve this? If I wanted to be able to modify the template without re-compiling the app, how could this be achieved with the second option? How could you store data representing the templates in a database such that it could be modified without having to re-compile the app?

• Radio Button selection Changes Toast on Android

  - by Bub

  I was writing a simple test application. There are two radio buttons within the app. There id's are "radio_red" and "radio_blue". I wanted to create an onClickListener event that read the text associated to the button and then returned a basic "Right" or "Wrong" toast. Here is a sample of the code: private OnClickListener radio_listener = new OnClickListener() { public void onClick(View v){ RadioButton rb = (RadioButton) v; String ans = rb.getText().toString(); String an1 = ""; if (ans.trim() == "Yes") { ans = "That's Right."; } else if (ans.trim() == "No") { ans = "thats wrong."; } else { ans = "none."; } Toast.makeText(v.getContext(), ans , Toast.LENGTH_SHORT).show(); } So far no joy. Here is my code snippet. I've checked my "main.xml" and the text associated to the buttons are referneced correctly. I added trim to make sure of that. However, all that is ever returned in the toast is "none." What am I missing? Thanks in advance for any help.

• sudo changes PATH - why?

  - by Michiel de Mare

  This is the PATH variable without sudo: $ echo 'echo $PATH' | sh /opt/local/ruby/bin:/usr/bin:/bin This is the PATH variable with sudo: $echo 'echo $PATH' | sudo sh /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin As far as I can tell, sudo is supposed to leave PATH untouched. What's going on? How do I change this? (This is on Ubuntu 8.04). UPDATE: as far as I can see, none of the scripts started as root change PATH in any way. From man sudo: To prevent command spoofing, sudo checks ``.'' and ``'' (both denoting current directory) last when searching for a command in the user's PATH (if one or both are in the PATH). Note, however, that the actual PATH environment variable is not modified and is passed unchanged to the program that sudo executes.

• Iframe auto-height not working when page changes in IE

  - by DisgruntledGoat

  I have an iframe in a page, with the following auto-height script. function autoHeight(e) { if ( e.contentDocument ) { e.height = e.contentDocument.body.offsetHeight + 35; } else { e.height = e.contentWindow.document.body.scrollHeight + 35; } } document.domain = "totalstudents.co.uk"; var ifr = document.getElementById('housingdata'); ifr.onload = function() { autoHeight(ifr); } The iframe resizes fine when the outer page is loaded, but when I go to a new page in the iframe, scrollbars appear and the page does not get resized in Internet Explorer. In other browsers the iframe gets resized, because the onload event fires each time. I'm using IE8 but the outer page is setting it to IE7 compatibility mode. Is there a workaround for IE?

• Need to recover local changes overwritten by p4 revert

  - by Nayn

  Hi, I had a pending changelist in my workspace. By mistake I reverted one of the files by reverting to depot. Eclipse wiped off the local history. I am not sure if perforce keeps any history for pending changelists. Could someone tell me if it is possible to recover such file. Thanks Nayn

• Which is more flexible in regards to database changes, EF 4 or Linq to SQL

  - by JBeckton

  Reading about both Linq to SQL and Entity Framework I have developed the impression that EF is more suitable for apps that get data from multiple data sources. But as I am reading about MVC2 models I see an example where EF is more loosely coupled with your data model. If I have to add or remove some columns from a table then what is involved in updating my model or DAL with each of these implementations?

• Storing a jpa entity where only the timestamp changes results in updates rather than inserts (desire

  - by David Schlenk

  I have a JPA entity that stores a fk id, a boolean and a timestamp: @Entity public class ChannelInUse implements Serializable { @Id @GeneratedValue private Long id; @ManyToOne @JoinColumn(nullable = false) private Channel channel; private boolean inUse = false; @Temporal(TemporalType.TIMESTAMP) private Date inUseAt = new Date(); ... } I want every new instance of this entity to result in a new row in the table. For whatever reason no matter what I do it always results in the row getting updated with a new timestamp value rather than creating a new row. Even tried to just use a native query to run an insert but channel's ID wasn't populated yet so I gave up on that. I've tried using an embedded id class consisting of channel.getId and inUseAt. My equals and hashcode for are: public boolean equals(Object obj){ if(this == obj) return true; if(!(obj instanceof ChannelInUse)) return false; ChannelInUse ciu = (ChannelInUse) obj; return ( (this.inUseAt == null ? ciu.inUseAt == null : this.inUseAt.equals(ciu.inUseAt)) && (this.inUse == ciu.inUse) && (this.channel == null ? ciu.channel == null : this.channel.equals(ciu.channel)) ); } /** * hashcode generated from at, channel and inUse properties. */ public int hashCode(){ int hash = 1; hash = hash * 31 + (this.inUseAt == null ? 0 : this.inUseAt.hashCode()); hash = hash * 31 + (this.channel == null ? 0 : this.channel.hashCode()); if(inUse) hash = hash * 31 + 1; else hash = hash * 31 + 0; return hash; } } I've tried using hibernate's Entity annotation with mutable=false. I'm probably just not understanding what makes an entity unique or something. Hit the google pretty hard but can't figure this one out.

• Safari and Chrome back button changes hidden and submit values in forms

  - by OverClocked

  The following problem happens on both Safari and Chrome, so probably a WebKit issue. Page A: a page that requires you to login to see, contains a form that has a type=submit button, with name=submit, and value=a Page B: some other page Page C: ask user to login page, contains a form with a type=submit button, with name=submit and value=c User visits page A, then page B. Then idles and the user's login session times out. User hits back button to go back to page A. Browser redirects user to page C. On Safari and Chrome, when C is rendered, the form on page C has the type=submit button, name=submit, but value shows up as "a". If you reload while on page C, "c" appears as the value of the name=submit button. The same problem appears with type=hidden input fields; when user hits back button, their values are also changed to some other value from some other form. Also, this problem also shows up w/o the redirect, with just submit then back. In this case the previous page renders with incorrect values for hidden and submit CGI variables. So far the only fix I can come up with is use Javascript to reset the type=hidden and type=submit variable values, after page C loads, to make sure the values are correct. But that's not clean and universally applicable. Short of WebKit fixing this error, has anyone ran into a better workaround? Thanks.

• PHP Session Id changes between pages

  - by willl69

  Hi All, I have a problem where i am losing the PHP session between 2 pages. The session_start() is included in a file called session-inc.php into every page requiring a session to be set. This works for all pages on the site except one particular page, member-profile.php. When this page is visited a new session with a different id (same session name) is set and used instead. A few more details: Session name is set manually All pages are on the same server under the same domain name If i put an additional session_start() above the include('session-inc.php') in the member-profile.php file, the session is carried over correctly I have tried setting the session_cookie_domain and session.session_name in the .htaccess, this worked for this domain but it stopped the session being passed over to out payment domain We are running apache 2.2.6 with php 5.2.5 Putting the session_start() above the include('session-inc.php') in the member-profile.php file is the quick and dirty fix for this problem, but i am wondering if anybody know why this would be happening. Cheers Will

• CFEXCHANGECONNECTION error when username changes.

  - by Tom Hubbard

  We are attempting to connect to an Exchange server through CFEXCHANGECONNECTION on ColdFusion 9 to retrieve email. We can connect with a number of users. However, some users cannot connect. We end up with the following error: Cannot access Exchange server as a web application at <server> It turns out that the users who cannot connect either have a ampersand in there username or they have changed there username with CFLDAP. So, if I perform a CFLDAP on a working user and change the userPrincipalName and sAMAccountName the user will begin getting the error above. If I change it back to what it was to start with, the error will go away. Any ideas? EDIT The ampersand part seems to be misleading. Essentially we found the problem because of the ampersand. However, for working users who did not have an ampersand, the error will begins showing up if their username is changed to something that does not have an ampersand.

• Log session and session changes of a asp.net web user

  - by Johan Wikström

  This is going to be a quite broad question, and any suggestions, examples, links are very welcome! I'm looking for a good way to log my users session, and actions on the site up to a certain point. The site in question is a site for doing bookings. The users start with doing a search, doing a few steps of data gathering and selections and end up with a booking. So what I need to implement is some kind of logging of the current session variables at each step the user takes. And perhaps some other valid information. Logging should preferably be done to the a database. At the end i would like to associate all these session with a booking reference. The goal is to later if something goes wrong with the booking or we need to investigate a situation have all information we need. I understand log4net is a popular choice for logging, and used it a bit myself for simple purposes, but can not find any good examples regarding my situation. This should be a common situation, i'm curious how others do it.

• Printing a variable only when it changes?

  - by user1781639

  First off, my question was a little vague or confusing since I'm not really sure how to phrase my question to be specific. I'm trying to query a database of stockists for a Knitting company (school project using PHP) but I'm looking to print the city as a heading instead of with each stockists information. Here is what I have at the moment: $sql = "SELECT * FROM mc16korustockists where locale = 'south'"; $result = pg_exec($sql); $nrows = pg_numrows($result); print $nrows; $items = pg_fetch_all($result); print_r($items); for ($i=0; $i<$nrows2; $i++) { print "<h2>"; print $items[$i]['city']; print "</h2>"; print $items[$i]['name']; print $items[$i]['address']; print $items[$i]['city']; print $items[$i]['phone']; print "<br />"; print "<br />"; } I'm querying the database for all of the data in it, the rows being ref, name, address, city and phone, and executing it. Querying the number of rows then using that to determine how many iterations for the loop to run is all fine but what I'd like to have is for the h2 heading to appear above the for ($i=0;) line. Trying just breaks my page so that might be out of the question. I figure I'd have to count the number of entries in 'city' until it detects a change then change the heading to that name I think? That or make a heap of queries and set a variable for each name but at point, I might as well do it manually (and I highly doubt it would be best practice). Oh, and I'd welcome any critiques to my PHP since I'm just starting out. Thanks and if you need any more information, just ask! P.S. Our class is learning with PostgreSQL instead of MySQL as you can see in the tags.
