• ASP control event handler not firing on postback?

  - by Polaris878

  Hello, I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago. We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too... Thanks

• Python/C "defs" file - what is it?

  - by detly

  In the nautilus-python bindings, there is a file "nautilus.defs". It contains stanzas like (define-interface MenuProvider (in-module "Nautilus") (c-name "NautilusMenuProvider") (gtype-id "NAUTILUS_TYPE_MENU_PROVIDER") ) or (define-method get_mime_type (of-object "NautilusFileInfo") (c-name "nautilus_file_info_get_mime_type") (return-type "char*") ) Now I can see what most of these do (eg. that last one means that I can call the method "get_mime_type" on a "FileInfo" object). But I'd like to know: what is this file, exactly (ie. what do I search the web for to find out more info)? Is it a common thing to find in Python/C bindings? What is the format, and where is it documented? What program actually processes it? (So far, I've managed to glean that it gets transformed into a C source file, and it looks a bit like lisp to me.)

• Background-image toggle using jquery

  - by Jon

  Hi all, bit of a jquery rookie here trying to get something to work. Basically I have a div with a class "nav" and inside that div is a nav list. I want to change the background-image of "nav" when hovering over an item in the navlist, so I made this unsuccesful effort: enter code here $(function(){ $("li#hover-first").mouseover(function(){ $("div.nav").removeClass("nav").addClass("navbg"); .mouseout(function(){$("div.nav").removeClass("navbg").addClass("nav"); }); So the idea is, once the first li item is hovered over, the div with classname "nav" has it's class removed and has "navbg" added (which has the alternate background image). Obviously this isn't working, so any help would be greatly appreciated...thanks.

• OOWrite is to LaTeX as OODraw is to?

  - by grimborg

  I'm looking for a tool to nicely generate single-page PDFs. My needs are: Able to put a PDF/EPS/... as a background Absolute positioning Able to define tables, lists Able to rotate blocks Reasonably easy syntax (will be used to automatically generate many similar looking documents) Easily usable from Python Free or very cheap In essence I'm looking for the tool X that is to OODraw/CorelDraw/... as LaTeX is to OOWrite/MS Word. I've looked at webkit2pdf and a headless OODraw, but both seem a bit of an overkill. XML-FO has some limitations such as not being able to predict how many pages your document spans. Reportlab is pricey. Any ideas? Thanks!

• Need some clarification with Patterns (DAO x Gateway)

  - by Marcos Placona

  Me and my colleagues got into this discussion early this morning, and our opinions started to clash a bit, so I decided to get some impartial advice here. One of my colleagues reckons that the DAO should return an object (populated bean). I think it's completely fine when you're returning a recordset with only one line, but think it's overkill if you have to return 10 lines, and create 10 separate objects. I on the other see that the difference between DAO and Gateway pattern is that the gateway pattern will allow you to return a recordset to your business class, which will therefore deal with the recordset data and do whatever it needs to do. My questions here are: Which assumptions are correct? What should the return type be for a DAO (i.e. getContact() - for one record) Should getContacts() (for multiple records) even be on the DAO, if so, what's it's returntype? We seem to be having some sort of confusion about DAO and Gateway Patterns. Should they be used together? Thanks in advance

• Put logic behind generated LinqToSql fields

  - by boris callens

  In a database I use throughout several projects, there is a field that should actually be a boolean but is for reasons nobody can explain to me a field duplicated over two tables where one time it is a char ('Y'/'N') and one time an int (1/0). When I generate a datacontext with LinqToSql the fields off course gets these datatypes. It would be nice if I don't have to drag this stupid choice of datatype throughout the rest of my application. Is there a way to give the generated classes a little bit of logic that just return me return this.equals('Y'); and return this==1; Preferably without having to make an EXTRA field in my partial class. It would be a solution to give the generated field a totally different name that can only be accessed through the partial class and then generate the extra field with the original name with my custom logic in the partial class. I don't know how to alter the accesibility level in my generated class though.. Any suggestions?

• Sort a set of multidimensional arrays by array elements

  - by Joseph Carrington

  Let's say I've started here: $arr[0] = array('a' => 'a', 'int' => 10); $arr[1] = array('a' => 'foo', 'int' => 5); $arr[1] = array('a' => 'bar', 'int' => 12); And I want to get here: $arr[0] = array('a' => 'foo', 'int' => 5); $arr[1] = array('a' => 'a', 'int' => 10); $arr[1] = array('a' => 'bar', 'int' => 12); How can I sort the elements in an array by those elements elements? Multidimensional arrays always feel like a little bit more than my brain can handle (-_-) (until I figure them out and they seem super easy)

• Creating a new project from a project skeleton using git

  - by asciitaxi

  In order to get a new django project up and running faster, I'd like to maintain a separate "project skeleton" on which I base all my new projects. It would be great if, as I improved the skeleton, I could bring those improvements into my active projects. How can I accomplish this with git? So, maybe in my remote git repository machine I would have 1 repo for each project and one for the skeleton? proj-A-repo proj-B-repo skeleton-repo If I want to create a new proj-C locally based on the skeleton, then push my local changes up to the remote server in a new repo called proj-C-repo, how might I do this? I've read through quite a bit of git documentation, but I'm confused about how to go about this. Do I need to clone the skeleton, or create an empty repo and then track a remote branch, or something else?

• GWT Internet Explorer Problem

  - by bhargava

  Hi All, I am running into a problem which is quite a bit surprising.I have an GWT application,which i can run perfectly fine on Firefox,but the same GWT application does not open up in Internet Explorer. When using Firefox i use <set-property name="user.agent" value="gecko1_8"/> and when i want to run in Internet Explorer i change it to <set-property name="user.agent" value="ie8"/> and debug.This way i am sure that the problem i am having is not related to deferred binding. When using the Internet Explorer (IE 8) i cannot even get into the onModuleLoad() part of my application.It looks as if Internet Explorer has downloaded all its stuff ,but has nothing to display. Is there something that i am missing here Thanks Bhargava

• Do you take the pain of learning it or use an out of the box solution?

  - by Mantorok

  Hi all What I'm getting at here is being presented with a control or framework that does 95% of what you want but has its shortcomings when opposed to learning how to do it yourself. To give a good example (ASP.Net) UpdatePanel vs DIY JS/JSON. The UpdatePanel gives you AJAX instantly without doing anything additional, however I've come to learn that its shortcomings are mainly that it's a bit of a hack and performs badly on busy pages and I've found myself having to scrap UpdatePanels in favour of rolling my own JS, and I've now made it a habit to fully investigate any shortcomings in out-of-the-box solutions, as I've been stung by this experience. So I guess what I'm asking is: Is it better to find out how to DIY or is it considered a better approach to try the available solution and risk going a full circle? Obviously I've only targetted a single control, but it is a very attractive control to people learning AJAX - I'm sure there are others out there. Sorry if dupliate. Thanks

• MySQL Trigger with dynamic table name

  - by Thomas

  I've look around a bit and can't quite find an answer to my problem: I want a trigger to execute after an insert on a table and to take that data that is being inserted and do two things Create a new table from the client id and partner id Insert the 'data' that just was inserted into the new table I am fairly new to the Stored procedures and triggers so I came up with this but am having difficulty debugging it: delimiter $$ CREATE TRIGGER trg_creas_insert BEFORE INSERT ON tracking.creas for each row BEGIN DECLARE @tableName varchar(40); DECLARE @createStmnt mediumtext; SET @tableName = concat('crea_','_', NEW.idClient_crea,'_',NEW.idPartenaire_crea); SET @createStmnt = concat('CREATE TABLE IF NOT EXISTS', @tableName, '( `data_crea` mediumtext NOT NULL ) ENGINE=MyISAM AUTO_INCREMENT=29483330 DEFAULT CHARSET=utf8 PACK_KEYS=0'); PREPARE stmt FROM @createStmnt; EXECUTE stmt; INSERT INTO @tableName (data_crea) values (NEW.data_crea); END$$ delimiter ; Thoughts?

• Emacs: Define a function which loads the file where the function itself is defined

  - by damd

  I'm refactoring a bit in my Emacs set up and have come to the conclusion that I want to use a different init file than the default one. So basically, in my ~/.emacs file, I have this: (load "/some/directory/init.el") Up until now, that's been working just fine. However, now I want to redefine an old command that I've used for ages, which opens my init file: (defun conf () "Open a buffer with the user init file." (interactive) (find-file user-init-file)) As you can see, this will open ~/.emacs no matter what I do. I want it to open /some/directory/init.el, or wherever the conf command itself is defined. How would I do that?

• Why does my program occasionally segfault when out of memory rather than throwing std::bad_alloc?

  - by Bradford Larsen

  I have a program that implements several heuristic search algorithms and several domains, designed to experimentally evaluate the various algorithms. The program is written in C++, built using the GNU toolchain, and run on a 64-bit Ubuntu system. When I run my experiments, I use bash's ulimit command to limit the amount of virtual memory the process can use, so that my test system does not start swapping. Certain algorithm/test instance combinations hit the memory limit I have defined. Most of the time, the program throws an std::bad_alloc exception, which is printed by the default handler, at which point the program terminates. Occasionally, rather than this happening, the program simply segfaults. Why does my program occasionally segfault when out of memory, rather than reporting an unhandled std::bad_alloc and terminating?

• Showing value of UISlider inside App Prefs?

  - by Garrett H

  I have a settings bundle, working perfectly, that I would like to customize a bit. I have, among other things, a PSSliderSpecifier and a PSTitleValueSpecifier. What I would like to do is change the value of the PSTitleValueSpecifier to show the current value of the slider, preferably updating every time the slider's value changes (Actually, what I'd like even more would be displaying the slider's value on the same row as the slider). I know the settings bundle is rather strict about what you're allowed to do in it, but is there any way of doing this?

• Can't figure out how to code my css

  - by JF

  Hi, I'm a new poster in stackoverflow. The community seems really nice so I'll go ahead and post my question. I'm trying to style a asp.net MVC2 form so that instead of having all the fields on a strait line, I would like to have it like so: Label: Text field Label: Text field I know you could do that with a table but I would like to use CSS to accomplish that. I know a little bit about css but not enough to figure out what to do. The only thing I came close to was to but my fields as a unorder list then styling the li item. Thank you for your help!

• How should I deal with persisting an Android WebView if my activity gets destroyed while showing ano

  - by Shaun Crampton

  Hi, I'm building an Android application that's based around an enhanced WebView (based on PhoneGap). I've enhanced the WebView so that from JavaScript running inside you can invoke the native contact picker to choose a phone number (which may be supplied by Facebook for example). The problem I have is that the native contact picker runs in an activity in another process and the Android docs say that while another activity is open my activity may get destroyed due to memory constraints. I haven't actually seen this happen in my application but if it did then I'm guessing my WebView's state would be destroyed and the code that was waiting for the picked contact would be terminated. It seems a bit crazy that the activity requesting a contact could be destroyed while the contact picker is open. Does anyone know if that does indeed happen? Is there a way to persist the state of the WebView if it does? Thanks, -Shaun

• Returning values from Swing using invokeAndWait

  - by Joonas Pulakka

  I've been using the following approach to create components and return values from Swing to/from outside the EDT. For instance, the following method could be an extension to JFrame, to create a JPanel and add it to the parent JFrame: public JPanel threadSafeAddPanel() { final JPanel[] jPanel = new JPanel[1]; try { EventQueue.invokeAndWait(new Runnable() { public void run() { jPanel[0] = new JPanel(); add(jPanel[0]); } }); } catch (InterruptedException ex) { } catch (InvocationTargetException ex) { } return jPanel[0]; } The local 1-length array is used to transfer the "result" from inside the Runnable, which is invoked in the EDT. Well, it looks "a bit" hacky, and so my questions: Does this make sense? Is anybody else doing something like this? Is the 1-length array a good way of transferring the result? Is there an easier way to do this?

• How to explain to a client that you've gone over-budget and you'll need more money/time to deliver w

  - by General Tapioca

  My situation is that I have agreed on a per-project proposal with the client. The proposal is vague, but still names functionality in a way that can be argued as to whether it's included or not, while leaving some room for interpretation. I originally pressed as much as I could to get a per-month contract, arguing that the project is mostly non-predictable, but the client refused. Being a small company, I had to fold and signed a contract on an estimate based on my group's estimations. At this point we have reached completion on about 85% of the features (we think) but we ran out of budget. We have been working for almost two years with this client in previous contracts, and we have delivered a good product that they are happy with, so we have a good standing relationship. More info: -There has been a bit of scope-creep, but I don't think enough for me to hide behind that argument -We've been delivering partial releases about monthly. -We don't have systematic user-testing in place.

• Rails: How to produce 404 or redirect upon undesired url exploitation?

  - by Baby Diego

  I want to hide the urls for editing users and their profiles behind safer and meaningful urls. For instance, I want /user/13/edit to be /settings/account and /user/13/profile/edit to be /settings/profile. I managed to achieve that, but for that I had to load the user information from the current_user bit from the session. Like so: # users_controller def edit @user = current_user end # profiles_controller def edit @user = current_user @profile = @user.profile end But now, since I can't compare @user.id from the params with the current_user in the session, how can I stop the old urls (/user/13/edit and /user/13/profile/edit) from being exploitable? They always load the forms for the current user, so there's no harm done, but I'd be more comfortable if they just produced a 404 error or something. Thanks in advance.

• Saving contents of ApplicationState in ASP.Net (MVC)

  - by Saqib

  I have an internal app used to edit XML files on disk. The XML files are loaded into an object model which is stored in ApplicationState. I need to save this data. The one option is to do this every time the user changes some data. However, this seems a bit inefficient - writing the data out to disk each time a change is made. Instead, is it possible to be notified whenever the user closes their browser, plus just before the web server exits? Thus, the data would be saved each time a session ends, plus when the computer shuts down, etc. I thought that Application_End(), Application_Error() and Session_End() in Global.asax would provide this, but these methods don't seem to be called.

• SQL Server Command Timeouts Timeout expired. The timeout period elapsed prior to completion of the o

  - by user104295

  Hi there, we've had a ASP.NET web application deployed for a number of years now.... last week we migrated to a slightly slower server to save some money. Now we're frequently getting command timeouts: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding This is understandable in that a slower server will take longer to produce results; take longer time and produce a timeout. Is there any system-wide way to get SqlClient to set a longer timeout? We cannot change the code, as it's everywhere... we're using multiple data access technologies as well. Maybe there's a default command timeout setting on a connection string? We just need to increase it by 30 seconds; we're happy to wait a bit longer for queries to return. thanks

• 2008 Datacenter Word Automation issue

  - by Brad

  We have an application that uses word automation. It works fine under Windows XP, but does not work on our Windows Server 2008 64-bit virtual machine running on VMware ESX unless it is running as the domain administrator. Under any other account (including a local admin), Word starts, uses a lot of CPU for 40 seconds when opening a document, and then just hangs. Our application does not access anything not on the local machine, and this machine is not being used for anything else (not a domain controller, etc). I know others have posted similar issues, with the solution of creating a Desktop folder somewhere under the windows directory. We did this, and it did not solve the problem (Word did not get as far as it did before we did this though). Please don't turn this into a thread about why I am trying to do this, whether I should do this, or whether I need to. For argument sake, I don't need to do this, but understanding what privilege a local admin does not have that is needed to do this is a legitimate concern.

• Evenly distribute items on the screen

  - by abolotnov

  I am trying to solve this little puzzle (the algorithm): I have N image icons and I want to distribute them evenly on users screen. Say, I put them in a table. If there is one image, there will be one cell in a table. If two - one row with two columns, if three - one row and three columns, if four - two rows, two columns... and so on until row space is gone and since then the table should only grow in columns without adding extra rows. I'm trying to figure an algorithm for this and perhaps this is something that has a solution already somewhere? My attempt is so far something like this: obtain_max_rows() obtain_visible_columns() if (number_of_pictures > max_rows*max_columns) { columns = roundup(number_of_pictures/max_rows) for(max_rows){generate row;for columns{generate column}} } else { **here comes to trouble...** } This logic is bit silly though - it somehow needs to think cases where there are 12 pictures on first screen and 2 on the other trying to balance it say 8/6 or somehow like that.

• SQLite doesn't have booleans or date-times.

  - by DanM

  I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not as bad as I fear. If you have any experience with this or a similar scenario, how did you handle it?

• Is php fileinfo sufficient to prevent upload of malicious files?

  - by Scarface

  Hey guys, I have searched around a bit, and have not really found a professional type response to how to have secure fileupload capability so I wanted to get the opinion of some of the experts on this site. I am currently allowing upload of mp3s and images, and while I am pretty confident in preventing xss and injection attacks on my site, I am not really familiar with fileupload security. I basically just use php fileinfo and check an array of accepted filetypes against the filetype. For images, there is the getimagesize function and some additional checks. As far as storing them, I just have a folder within my directory, because I want the users to be able to use the files. If anyone could give me some tips I would really appreciate it.
