• Windows service thread not updating database until complete

  - by dfarney

  I have a windows service with a FileSystemWatcher. When a new file is dropped in my folder a new thread is created, started, and I begin processing the file. Throughout this process I am making updates to the database (Linq to SQL) to keep track of the file's processing progress. Problem is none of my database updates are reflected throughout the process, just an update after everything has been completed. Any ideas? Note: when doing dev/testing my code was in an aspx page and worked great, but when I put it in a windows service I no longer get the progress updates. Thanks!

• How do you escape double quotes inside a SQL fulltext 'contains' function?

  - by Richard Davies

  How do you escape a double quote character inside a MS SQL 'contains' function? SELECT decision FROM table WHERE CONTAINS(decision, '34" AND wide') Normally contains() expects double quotes to surround an exact phrase to match, but I want to search for an actual double quote character. I've tried escaping it with \, `, and even another double quote, but none of that has worked. P.S. I realize a simple example like this could also be done using the LIKE statement, but I need to use the fulltext search function. The query I provided here has been simplified from my actual query for example purposes.

• Cruise control: should deployment be in tasks or publishers?

  - by Aligma

  I'm setting up a Cruise Control configuration for one project. I have an <msbuild> task under <tasks>. It seems that I have the option of putting my file deployment under either <tasks> or <publishers>. Logically I would think it should reside under <publishers> but none of the examples I have seen online work this way. Should deployment happen within in <tasks> or <publishers>?

• Django: Site-Wide URL Prefix

  - by Tom

  I've built a Django site that will live at the root when it's live. Right now it's functioning perfectly at the IP address. For testing purposes, the client has pointed a proxy url at it, but the url has /folder/path in it, so none of the URL patterns match. I put (/folder/path)? into all the url patterns so they now respond, but all of the links are broken because I'm using the {% url %} tag and while the url patterns will match the optional path, they don't include it in that tag. Clearly I can just hard-code /folder/path into all of my urls (well, into all of the url includes) until testing is complete, but is there a better way to do this?

• Libraries for making a voice chat application

  - by Eric

  My development team is going to build a voice chat application. Our plan is to use a pre-made library just for this purpose, but we haven't found any good one after days of searching the internet, so I thought I would consider a question here! So the question is: What library / project do you recommend? We are deadly serious with this, so it needs to be a good working one. Preferable an open-source one as well. We have been looking at some XMPP libraries and projects, but none seems to be up-to-date, tested and well-documented.

• Why does this program require MSVCR80.dll?

  - by Runner

  #include <gtk/gtk.h> int main( int argc, char *argv[] ) { GtkWidget *window; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_widget_show (window); gtk_main (); return 0; } I tried putting various versions of MSVCR80.dll under the same directory as the generated executable(via cmake),but none matched. Is there a general solution for this kinda problem? UPDATE Some answers recommend install the VS redist,but I'm not sure whether or not it will affect my installed Visual Studio 9, can someone confirm?

• Entity Framework (4.0) how to exclude a related table.

  - by Kohan

  I have just updated to using EF 4.0 where before i was using Linq 2 SQL. I have a query: var UserList = this.repository.GetUsers(); return Json(UserList, JsonRequestBehavior.AllowGet); This was generating an error: "A circular reference was detected while serializing an object of type" This prompted this code which worked fine in L2S: var UserList = this.repository.GetUsers(); foreach (User u in UserList){ u.Subscriptions = null; } return Json(UserList, JsonRequestBehavior.AllowGet); How can i stop EF from looking into the Subscriptions table, i just want the Userlist, none of the related properties and the above example does not seem to work for this. Cheers, Kohan

• Co-opt popular abandonware opensource project?

  - by Mike Bouck

  Here's the scenario: A popular open source project is used/loved by many but has become stale due to the fact that the last drop came out nearly a year ago. Many bugs/feature requests/fixes have been logged in the interim and everyone is getting by via downloading the trunk and building custom/private builds with the changes incorporated. The copyright is simple -- there is none and the code is in the public domain. The project owner spins the project as community open source and has set up a sourceforge site, but to date (5 years running now) has yet to accept one contributor. In other words the "community" is a community of one. The project owner takes great pride in the project and has obviously contributed a lot of time/effort but for whatever reason has has seemingly abandoned the project and is unresponsive when offers of help are made. So, the question, should the community fork the codebase, set up a new community site, and take matters in their own hands?

• MySQL indexes - what are the best practises?

  - by Haroldo

  I've been using indexes on my mysql databases for a while now but never properly learnt about them. Generally I put an index on any fields that i will be searching or selecting using a WHERE clause but sometimes it doesn't seem so black and white. What are the best practises for mysql indexes? example situations/dilemas: If a table has six columns and all of them are searchable, should i index all of them or none of them? . What are the negetive performance impacts of indexing? . If i have a VARCHAR 2500 column which is searchable from parts of my site, should i index it?

• Can't add libraries to Eclipse Android project

  - by neuromancer

  I'm trying to get the Hackbook for Android project to work in Eclipse. One of the things I need to do is remove that invalid reference and include that project I made. I did this before, but then I started over and now it doesn't work. Here is where I add the project. If I click "Apply" and then "OK" everything seems to be fine, but it isn't, because when I go back to this screen, none of the changes I made are there. Why isn't it saving my changes? How am I supposed to do this?

• How can I not render a button in my view if a given property off my model has no value?

  - by Lee Warner

  I'm new to web development. In my view, I want to conditionally show a button if Model.TemplateLocation (which is a string) is not null or empty. Below is the code that is rendering the button currently: <div class="WPButton MyButton"> <%=Html.ActionLink(Model.TemplateLinkName, "DownloadTemplate", "ExternalData", new ArgsDownloadTemplate { Path = Model.TemplateLocation, FileName = Model.TemplateFileNameForDownload }, new{})%> </div> Can I wrap some C# code in the <% %'s to test for Model.TemplateLocations value before I render that? I was told to look into @style = "display:none" somehow. Could that be what I need?

• Jquery Slider PNG black borders IE8

  - by Thomas

  Greetings, I'm having a lot of trouble with the IE8 buy of getting black borders when using a JQUERY slider, with PNG transparent images. Using a slightly modified version of the Nivio slider. I have searched high and low for fixes and blocks of code but so far none have worked. What happens is that as soon as the img cycles it gets the black border and looks like shit (only in IE8). Does anyone know a working fix for this? Or do we just have to ban IE from all computers?

• How do i hide html until its processed with javascript?

  - by acidzombie24

  I am using some JS code to transform my menu into a drilldown menu. The problem is before it runs the JS you see a BIG UGLY mess of links. On their site its solved by putting the js at the top. Using recommendations by yahoo/YSlow i am keeping the JS files at the bottom. I tried hiding the menu with display:none then using jquery to .show(), .css('display', ''), .css('display', 'block') and they all lead up to a messsed up looking menu (i get the title but not the title background color or any links of the menu) How do i properly hide a div/menu and show it after being rendered?

• how can I get jquery.sIFR plugin to display sIFR-alternate text for print?

  - by apeBoy

  I'm struggling with this. I've used the jquery sIFR plugin as opposed to sIFR it prevented conflicts with other jquery I am using on my pages. It works fine in its prime function: replacing html text with Flash. However, the .sIFR-alternate class is given an inline style of 'opacity: 0' which persists when flashblock is on. So alternate text does not appear. Neither does it appear when printng the page (yes I have included styles for sIFR-print). I've tried replacing the opacity:0 inline style with display: none but this causes height issues with the output flash. Any one else had this or have any ideas?

• regular expression not behaving as expected - Python

  - by philippe

  I have the following function which is supposed to read a .html file and search for <input> tags, and inject a <input type='hidden' > tag into the string to be shown into the page. However, that condition is never met:( e.g the if statement is never executed. ) What's wrong with my regex? def print_choose( params, name ): filename = path + name f = open( filename, 'r' ) records = f.readlines() print "Content-Type: text/html" print page = "" flag = True for record in records: if re.match( '<input*', str(record) ) != None: print record page += record page += "<input type='hidden' name='pagename' value='psychology' />" else: page += record print page Thank you

• continuous deployment with github pages and GAE python

  - by BPm

  I have a site hosted by google app engine. I've pushed all the html files to a github pages repo and what I want to do next is somehow make GAE listen to my github's changes. Like everytime i commit something new, GAE will deploy itself based on the changes. I've heared of drydrop but that was when github pages didn't exist yet. So what should i do next? I've set up a post-receive url , which is my appspot website, through the github's service hooks, added the CNAME file to my repo which contains my appspot url. Not sure if that's necessary. I've googled a lot on this but none really answers my question. or I just don't know the right search term for it. Thanks in advance

• Visual Studio 2010 debug minidump

  - by Snake

  Hi all, Consider the following code (written with Visual Studio 2010 and .NET 4.0) using System; namespace DumpTester { class Program { static void Main(string[] args) { int test = new Random().Next(); Console.WriteLine(test + new Random().Next()); Test(); } private static void Test() { throw new Exception(); } } } When running outside of Visual Studio you get this nice window of Microsoft Windows 7 that it is looking for a solution. Obviously, since this is my app, there is none. At that point I create a full dump file of my application with for example Process Explorer. I then open that dmp file from its location and try to debug. But whatever I try, it can't find the location of the source symbols. I tried putting the pdb next to the dump but it just doesn't find it. What am I doing wrong?

• Type hinting and optional attributes in PHP

  - by Álvaro G. Vicario

  I have a class method that deals with dates: public function setAvailability(DateTime $start, DateTime $end){ } Since item availability can have lower limit, upper limit, both or none, I'd like to make setAvailability() accept NULL values as well. However, the NULL constant violates the type hinting: $foo->setAvailability(NULL, $end); triggers: Catchable fatal error: Argument 1 passed to Foo::setAvailability() must be an instance of DateTime, null given And, as far as I know, I cannot have a DateTime instance with no value. (Can I?) For a reason I cannot grasp, this seems to work: public function setAvailability(DateTime $start=NULL, DateTime $end=NULL){ } ... $foo->setAvailability(NULL, $end); But it looks like a hack that works by pure chance. How would you deal with unset dates in PHP classes?

• Angularjs code/naming conventions

  - by Dalorzo

  Does anyone know if exists any official or most accepted reference for Angular naming conventions to use when we build our applications? Angular has a lot of different type of components such as filters, directives, services and so on. Wouldn't you agree that having a reference naming convention when we implement them in our applications will make sense? For example: If we need to create new filters how should we name them like [Something]Filter or filter[Something] or something else? And same applies for Controllers, Services, Directives and so on. Other things I wonder about is if variables/functions that belongs to the scope should have an special prefix or suffix. In some situations it may be useful to have a way to differentiate them from functions and other (none angular code).

• IE 8 Automatically Closing <header> tag

  Background I am currently working on the final QA of a responsive website and I'm having an issue with IE 8 and IE 7. My client deals with government contracting so their website needs to be compatible with IE 8 and IE 7. I am using Modernizr with html5shiv built in. I am loading Modernizr in the footer of a WordPress theme that was custom built for this project. I'm not missing a doctype or any other obvious code. I am using the following scripts, all of which are loaded in the footer of WordPress: jQuery 1.10.1 Modernizr 2.6.3 (click for config) respond.js 1.3.0 superfish jQuery Waypoints 2.0.3 jQuery Waypoints Sticky 2.0.3 The Situation I'm having an issue with IE 8 automatically closing a <header> tag.

• Is there a unified way to know if a node is visible or not?

  - by zneak

  Hello guys, I'd like to be able to know if a node is visible and rendered on screen. As far as I know, there are at least 3 standard and easy ways of making HTML nodes not visible: Setting opacity: 0; Setting display: none; Setting visibility: hidden. I could check for just these three, but I'm afraid people can get creative when it comes to ways of hiding contents: Sending the element offscreen using negative margins; Using a width or height of 0 and hiding overflow; many more I trust people to have developed. So I was wondering if there is a standard way of determining if a node is rendered to the screen. I'm pretty sure all major browsers determine it for themselves to accelerate drawing, so maybe it's somehow exposed.
