How to redirect a user to a new webpage after a Javascript Alert/confrim box

I have a client who wishes to have an alert/confirm box pop up when a user leaves the site, then based on what they choose, they will either stay on the page or go to a new page (would love if it would work in all browsers). I have been twiddling all day and have got this piece of code, but doesn't work too well. <script> window.onbeforeonload = function exitLeave(){var answer = confirm("You have not filled out your questionnaire yet") if (answer){ window.location = "http://www.google.com/"; } else{ alert("Cancel it !") } } </script> Any help would be greatly appreciated.

What are real-world examples of Gradle's dependency graph?

- by Michael Easter

As noted in the documentation, Gradle uses a directed acyclic graph (DAG) to build a dependency graph. From my understanding, having separate cycles for evaluation and execution is a major feature for a build tool. e.g. The Gradle doc states that this enables some features that would otherwise be impossible. I'm interested in real-world examples that illustrate the power of this feature. What are some use-cases for which a dependency graph is important? I'm especially interested in personal stories from the field, whether with Gradle or a similarly equipped tool. I am making this 'community wiki' from the outset, as it will be difficult to assess a 'correct' answer.

Having difficulty catching postgresql exception in sequel/ruby

- by mhd

I have postgresql table that has somekind of unique constraint. I have ruby script that will update this table. The ruby script should be able to switch to UPDATE instead of INSERT when this kind of error occured: PGError: ERROR: duplicate key value violates unique constraint CMIIW, sequel seems cannot catch this exception?? Anyway,sample code below is something that I would like to see to work but apparently not: @myarray.each do |x| fresh_ds = DB["INSERT INTO mytable (id, col_foo) values ('#{x}' ,'#{myhash[x]}')"] result = fresh_ds.insert catch Sequel::Error do fresh_ds = DB["UPDATE mytable set col_foo = '#{myhash[x]} where id = #{x}"] result = fresh_ds.update end end Maybe my ruby code is wrong or I missed something I don't know. Any solution? Thanks. UPDATE: code below works, the error is caught when unique constraint is violated. @myarray.each do |x| begin # INSERT CODE rescue Sequel::Error # UPDATE CODE end end

Is there a convention for organizing the include/exports in a large C++ project ?

- by BlueTrin

Hello, In a large C++ solution, is there a best/standard way to separate the include files necessary to build an intermediary DLL and the include files which will be used by the DLL clients ? We have grouped all the include files in a folder called Interface (for DLL interface), but there the customers have to either include the Interface folder as a default include folder or type the full name as: #include "ProjectName/Interface/myinterface.h" Wouldn't it be better to create a separate folder called exports where I would create a folder called ProjectName and put the include files there ? So that the customers would be typing: #include "ProjectName/myinterface.h" If I do the thing right above, then should I keep the files within the solution and produce a post build event (I use Visual Studio 2k5) to copy the files into the "export" folder (/ProjectName/) ? Or is it better to just include directly the files from this folder within my project (this is more direct and has less chances to cause maintenance issues ? I am more looking for advice than for a definite solution. Thank you for reading this ! Anthony

Compiling Qt for Windows 98

- by wrp

I need to support Windows 98. The Qt documentation claims this is possible, but there are no instructions. The distributed binaries don't run on Win98 and the majority of Qt applications I have sampled also don't. For several apps that do run on 98, I have asked authors how they did it, but the common answer is that it was accidental and they don't know what factors caused it. In searching the forums for help, I found only guesses that turned out to be wrong. For example, one belief is that to compile for Win9x, you must build the tools and the apps on that platform. Yet, things I found to run were built on newer versions of Windows. What is required to build the Qt dev tools and then applications for Win98? How about cross-compiling from WinXP or Linux? Are there specific components that can't be made to run on Win98? Are there particular difficulties with dynamic or static linking for Win98 support?

How can a C/C++ program put itself into background?

- by Larry Gritz

What's the best way for a running C or C++ program that's been launched from the command line to put itself into the background, equivalent to if the user had launched from the unix shell with '&' at the end of the command? (But the user didn't.) It's a GUI app and doesn't need any shell I/O, so there's no reason to tie up the shell after launch. But I want a shell command launch to be auto-backgrounded without the '&' (or on Windows). Ideally, I want a solution that would work on any of Linux, OS X, and Windows. (Or separate solutions that I can select with #ifdef.) It's ok to assume that this should be done right at the beginning of execution, as opposed to somewhere in the middle. One solution is to have the main program be a script that launches the real binary, carefully putting it into the background. But it seems unsatisfying to need these coupled shell/binary pairs. Another solution is to immediately launch another executed version (with 'system' or CreateProcess), with the same command line arguments, but putting the child in the background and then having the parent exit. But this seems clunky compared to the process putting itself into background. Edited after a few answers: Yes, a fork() (or system(), or CreateProcess on Windows) is one way to sort of do this, that I hinted at in my original question. But all of these solutions make a SECOND process that is backgrounded, and then terminate the original process. I was wondering if there was a way to put the EXISTING process into the background. One difference is that if the app was launched from a script that recorded its process id (perhaps for later killing or other purpose), the newly forked or created process will have a different id and so will not be controllable by any launching script, if you see what I'm getting at. Edit #2: fork() isn't a good solution for OS X, where the man page for 'fork' says that it's unsafe if certain frameworks or libraries are being used. I tried it, and my app complains loudly at runtime: "The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec()." I was intrigued by daemon(), but when I tried it on OS X, it gave the same error message, so I assume that it's just a fancy wrapper for fork() and has the same restrictions. Excuse the OS X centrism, it just happens to be the system in front of me at the moment. But I am indeed looking for a solution to all three platforms.

Google App Engine - SiteMap Creation for a social network

- by spidee

Hi all. I am creating a social tool - I want to allow search engines to pick up "public" user profiles - like twitter and face-book. I have seen all the protocol info at http://www.sitemaps.org and i understand this and how to build such a file - along with an index if i exceed the 50K limit. Where i am struggling is the concept of how i make this run. The site map for my general site pages is simple i can use a tool to create the file - or a script - host the file - submit the file and done. What i then need is a script that will create the site-maps of user profiles. I assume this would be something like: <?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>http://www.socialsite.com/profile/spidee</loc> <lastmod>2010-5-12</lastmod> <changefreq>???</changefreq> <priority>???</priority> </url> <url> <loc>http://www.socialsite.com/profile/webbsterisback</loc> <lastmod>2010-5-12</lastmod> <changefreq>???</changefreq> <priority>???</priority> </url> </urlset> Ive added some ??? as i don't know how i should set these settings for my profiles based on the following:- When a new profile is created it must be added to a site-map. If the profile is changed or if "certain" properties are changed - then i don't know if i update the entry in the map - or do something else? (updating would be a nightmare!) Some users may change their profile. In terms of relevance to the search engine the only way a google or yahoo search will find the users (for my requirement) profile would be for example by means of [user name] and [location] so once the entry for the profile has been added to the map file the only reason to have the search-bot re-index the profile would be if the user changed their user-name - which they cant. or their location - and or set their settings so that their profile would be "hidden" from search engines. I assume my map creation will need to be dynamic. From what i have said above i would imagine that creating a new profile and possible editing certain properties could mark it as needing adding/updating in the sitemap. Assuming i will have millions of profiles added/being edited how can i manage this in a sensible manner. i know i need a script that can append urls as each profile is created i know the script will prob be a TASK - running at a set freq - perhaps the profiles have a property like "indexed" and the TASK sets them to "true" when the profiles are added to the map. I dont see the best way to store the map - do i store it in the datastore i.e; model=sitemaps properties key_name=sitemap_xml_1 (and for my map sitemap_index_xml) mapxml=blobstore (the raw xml map or ror map) full=boolean (set true when url count is 50) # might need this as a shard will tell us To make this work my thoughts are m cache the current site map structure as "sitemap_xml" keep a shard of url count when my task executes 1. build the xml structure for say the first 100 urls marked "index==false" (how many could u run at a time?) 2. test if the current mcache sitemap is full (shardcounter+10050K) 3.a if the map is near full create a new map entry in models "sitemap_xml_2" - update the map_index file (also stored in my model as "sitemap_index" start a new shard - or reset.2 3.b if the map is not full grab it from mcache 4.append the 100 url xml structure 5.save / m cache the map I can now add a handler using a url map/route like /sitemaps/* Get my * as map name and serve the maps from the blobstore/mache on the fly. Now my question is does this work - is this the right way or a good way to start? Will this handle the situation of making sure the search bots update when a user changes their profile - possibly by setting the change freq correctly? - Do i need a more advance system :( ? or have i re-invented the wheel! I hope this is all clear and make some form of sense :-)

Selecting an item in an HTML SELECT list using keyboard doesnt trigger the CLICK event

- by Jimbo

I have an HTML select list which, when an item is selected, must show different information beneath it. The onclick or JQuery change events are triggered when a select list item is selected by being clicked on (mouse), but not when the user uses key presses (keyboard). Any idea what event to watch in order to determine when the selected list item has changed? Here is a BASIC test example: <select id="mylist" name="mylist"> <option value="">(none)</option> <option value="1">Test 1</option> <option value="2">Test 2</option> <option value="3">Test 3</option> </select> <span id="myspan"></span> <script type="text/javascript"> $("#mylist").change(function() { $("#myspan").html($("#mylist").attr("selectedIndex")); }); </script>

How do I dynamically load a js file using Prototype?

- by domagoj412

Hello, I am using prototype to load external js file (actually it is php file) dynamically. Like this: function UpdateJS(file) { var url = 'main_js.php?file='+file; var myAjax = new Ajax.Request( url, {method: 'get', onComplete: showResponseHeader} ); } function showResponseHeader (originalRequest) { $('jscode').innerHTML = originalRequest.responseText; } Container "jscode" is defined like this: <script type="text/javascript" id="jscode"></script> And it works! But if some different file is called, all the functions from previous one are preserved. And I don't want that. Anybody knows how to "unload" first js file when second one is called? (I also tried using Ajax.Updater function but the result is the same.) Update: It turns out that there is bigger problem: it only loads if function "UpdateJS" is in window.onload that is why it doesn't load anything else after that. So prototypes update it's maybe not such a good way for this...

Using WiX, how do I change a property of a subfolder of a virtual directory?

- by Joergen Bech

I have a hierarchy of Directory elements in a WiX script. I also have a component that creates a virtual directory (using IIS:WebVirtualDir), which points to the root of my Directory hierarchy. How do I change a property (e.g. AnonymousAccess) of a subfolder of the virtual directory, e.g. MyVirtualDir <<< this is the virtual directory root MyVirtualDir\MySubFolder <<< this is the subfolder for which I wish to change a property using WebDirProperties Please note that I do not wish to create a new virtual directory for the subfolder. I only wish to change a few security settings. The current script is too big to post here, but take a look at the WiX tutorial: 5.3 Web Directory. Suppose in that example that there was another Directory element named "MySubFolder" nested within the "InstallDir" element. What would then be the next step in order to set properties for "MySubFolder" without turning it into a virtual directory?

Why Doesn't This Java Code Skip Lines with #?

- by Nathan

I'm trying to allow an external .txt file that is read by a Java script be able to have some comments in the beginning of the file so others can easily edit it and add more to it. But if the file contains # (the sign designated for a line that is a comment) it just returns the error that there is a "Format Error in file" (the IOException - so it is getting past that first "IF"...) Can someone help? Here's the portion of the code that deals with commenting lines out of the .txt file being called earlier in the script: while ((line = br.readLine()) != null) { line = line.trim(); if (line.length() < 1 || line.charAt(0) == '#') { // ignore comments continue; } final String[] parts = line.split("="); if (parts.length != 2) { throw new IOException("Format error in file " + JLanguageTool.getDataBroker().getFromRulesDirAsUrl(getFileName()) + ", line: " + line); }

.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 do I select and group by a portion of a string?

Add all lines multiplied by another line in another table

- by russell

Hi, I hope I can explain this good enough. I have 3 tables. wo_parts, workorders and part2vendor. I am trying to get the cost price of all parts sold in a month. I have this script. $scoreCostQuery = "SELECT SUM(part2vendor.cost*wo_parts.qty) as total_score FROM part2vendor INNER JOIN wo_parts ON (wo_parts.pn=part2vendor.pn) WHERE workorder=$workorder"; What I am trying to do is each part is in wo_parts (under partnumber [pn]). The cost of that item is in part2vendor (under part number[pn]). I need each part price in part2vendor to be multiplied by the quantity sold in wo_parts. The way all 3 tie up is workorders.ident=wo_parts.workorder and part2vendor.pn=wo_parts.pn. I hope someone can assist. The above script does not give me the same total as when added by calculator.

How to hide nested form from jQuery under IE8

- by pduel

An html segment with a div containing a form: <div class="hide"> Form header <form action='' method='post'> .... form content here </form> form footer </div> <script type="text/javascript"></script> The jquery should hide the form, but does not do so under IE8. (version 8.0.60001) The form content gets hidden, as does the content within the class='hide' div but outside the form, but the form border continues to show, and retains its size. Does anybody have a workaround for this? jQuery is version 1.4.2 I tried to create a small problem demo in jsfiddle, but that site was not functional in the IE browser.

How can I include utility functions from another file into a Sproutcore unit test file?

- by Lauri

Lets say I have a few utility functions in file tests/utils/functions.js. I would like to use these functions from several unit test files. However, I'm not able to use them as the Sproutcore build system does not include any external files into the html page used to run the unit tests. Only application code and the code from the unit tests to be run are included. So is it possible to somehow include Javascript files to be used in unit test files in Sproutcore? I could add the functions.js file into some other directory inside my application to be able to use them. However, this is not what I want to do as the utility functions are useless in final production build and would only make my application larger.
