• How should I build a privacy drop-down (select) menu?

  - by animuson

  I'm trying to build something similar to Facebook's privacy selection menu, except without the 'custom' option. It will only list a few options such as 'show to all', 'show to friends only', or 'completely hidden'. Right now I'm thinking of using simple JavaScript to change a hidden input field to the new value they click on, so if they clicked on the division for 'show to friends only' it would change the corresponding field, say 'email_privacy', to 1. Is there a better way to do this or am I pretty much on track? P.S. I am not planning on using a select element, I was planning on building a custom drop-down menu using CSS since select elements are so highly non-customizable. I'm doing it this way to save space, rather than having this massive selection menu at the right which takes up a bunch of space. Note: I'm not really interested in using jQuery, that's just extra libraries and crap that I don't want to load. I can do it in JavaScript just as easily so I might as well use that.

• How to know start and kill processes within Java code (or C or Python) on *nix

  - by recipriversexclusion

  I need to write a process controller module on Linux that handles tasks, which are each made up of multiple executables. The input to the controller is an XML file that contains the path to each executable and list of command line parameters to be passed to each. I need to implement the following functionality: Start each executable as an independent Be able to kill any of the created processes independent of the others In order to do (2), I think I need to capture the pid when I create a process, to issue a system kill command. I tried to get access to pid in Java but saw no easy way to do it. All my other logic (putting info about the tasks in DB, etc) is done in Java so I'd like to stick with that, but if there are solutions you can suggest in C, C++, or Python I'd appreciate those, too.

• Compiled query using list of class objects in C#

  - by Sukan

  Hello , Can somebody help me out in creating compiled queries where input is to be a list of class objects? I have seen examples where Func<DataContext, somematchobject, IQueryable<T>> is created and compiled. But can I do something like Func<List<T>, matchObject, T>, and compile it? Basically I want an object(T) meeting certain conditions (as in matchObject) to be returned from a list of objects(List<T>). Will CompiledQuery.Compile help me in this? Please help me experts!!

• How can I manipulate the strip text of facet plots in ggplot2?

  - by briandk

  I'm wondering how I can manipulate the size of strip text in facetted plots. My question is similar to a question on plot titles, but I'm specifically concerned with manipulating not the plot title but the text that appears in facet titles (strip_h). As an example, consider the mpg dataset. library(ggplot2) qplot(hwy, cty, data = mpg) + facet_grid( . ~ manufacturer) The resulting output produces some facet titles that don't fit in the strip. I'm thinking there must be a way to use grid to deal with the strip text. But I'm still a novice and wasn't sure from the grid appendix in Hadley's book how, precisely, to do it. Also, I was afraid if I did it wrong it would break my washing machine, since I believe all technology is connected through The Force :-( Many thanks in advance.

• SQL: How can i update a value on a column only if that value is null?

  - by user321185

  Hey, I have an SQL question which may be basic to some but is confusing me. Here is an example of column names for a table 'Person': PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood Let's say that I input the row: 121312, Rayna, Pieterson, BMW123d, Brown, NULL, NULL Now I want to update the values for this person, but only if the new value is not null, Update: 121312, Rayna, Pieterson, NULL, Blonde, Fanta, NULL The new row needs to be: 121312, Rayna, Pieterson, BMW123d, Blonde, Fanta, NULL So I was thinking something along the lines of: Update Person(PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood) set Car = @Car (where @Car is not null), HairColour = @HairColour (where @HairColour...)... etc. My only concern is that I can't group all the conditions at the end of the query because it will require all the values to have the same condition. Can't i do something like Update HairColour if @HairColour is not Null

• parse/collator for php

  - by dramatic

  I'm pretty much a newbie at php (at the "install an app and try to tweak it a bit" stage). Is there a tool anywhere which can take a script which is spread over many files and show you all the code which is processed (for a given set of arguments passed to the script) in a single output? For example, I want to make a call to zen cart from a script in a different language, which returns a category listing without any surrounding page. So I want to be able to trace what the actual process is to generate that then strip off all the unwanted bits to create a custom script.

• JQuery Autocomplete CSS not working?

  - by gath

  I am trying to implement JQuery Autocomplete pluggi using Django. I've been able to wire the thing together and I can actually see the result back in the HTML template. My problem is that the JQuery Autocomplete CSS doesn't seem to work. The results I get are not well formatted/styled, and they have no background and you cannot even select them. What is it that am missing? I have these three files in my media folder same folder: autocomplete.js dimensions.js autocomplete.css In my html template I have the following function: $(function(){ setAutoComplete("tags", "tagResults", "/taglookup/?query="); }); My textfield looks like this; <input type="text" name="tags" value=""> Where do I put the tagResults in my HTML template document? Every time I try to introduce a DIV with id="tagResults", JQuery throws an error. Any ideas?

• Why would the first call to a KVC setter have an NSTextField instance as the argument?

  - by Stephen

  If I have a NSTextField bound through an NSObjectController to a model object, I would expect the setter of the model object to be called with an NSString as the argument, but instead, I receive the instance of the control that I am bound too the first time I am called. - (NSString *)property { NSLog(@"returning property"); return property; } - (void)setProperty:(NSString *)string { NSLog(@"recieved %@", string) } - (id) init { if (self = [super init]) { property = [[NSString alloc] initWithString:@"value"]; } NSLog(@"property is %@",property"); return self; } (The program doesn't run if you try anything in setProperty, because it tries to send NSString messages to string - which might be an NSTextField.) Console Output: 2010-05-12 14:19:14.096 Trouble[13108:10b] property is enter value 2010-05-12 14:19:14.100 Trouble[13108:10b] recieved <NSTextField: 0x1025210> 2010-05-12 14:19:14.106 Trouble[13108:10b] returning property

• ASP MVC Populate drop down list on jQuery add table row

  - by Jacob Huggart

  I have a page with several drop down lists that all have the same contents. The page starts out with only three ddls, but more need to be added based on user input. There is also other information associated with the drop down lists that is all in a table. So, when the user clicks a link I add a new row of textboxes and drop down lists to a table. When I add a row to my table, the new drop down lists are empty because there is no view data associated with them. How can I use ajax or jquery to pull the viewdata that I need to populate new drop down lists?

• php/mysql show data from chosen checkboxes

  - by Michael

  Hi. I have a table called FRUIT id type daysold 1 banana 5 2 apple 6 3 apple 4 4 peach 2 5 banana 6 What I would like is to have 3 checkboxes: Banana [ ] Apple [ ] Peach [ ] SUBMIT Then if I've only checked "Banana" and "Peach" the mysql output should only show me the rows that matches those two types. And the checkboxes should remain checked to highlight what was chosen. I can make the checkboxes but then that's about it really. I don't know how to properly get the info from the checkboxes and down to the WHERE argument in the MYSQL-code. Especially not with two types chosen. If it was just a dropdown menu with a single choice then I'd add the choice to the url and put WHERE type='$choice' - but I'm struggling with the multiple choices. I'm a bit of a novice at both php and mysql, so I'm a bit lost on this one.

• Sqlite3 Database versus populating Arrays

  - by Kenoy

  hi, I am working on a program that requires me to input values for 12 objects, each with 4 arrays, each with 100 values. (4800) values. The 4 arrays represent possible outcomes based on 2 boolean values... i.e. YY, YN, NN, NY and the 100 values to the array are what I want to extract based on another inputted variable. I previously have all possible outcomes in a csv file, and have imported these into sqlite where I can query then for the value using sql. However, It has been suggested to me that sqlite database is not the way to go, and instead I should populate using arrays hardcoded. Which would be better during run time and for memory management?

• php shuffle() returns one item

  - by mike

  Anyone have any idea why shuffle() would only return 1 item? when using: $array2 = shuffle($array1); with the following array($array1): Array ( [0] => 1 [1] => 5 [2] => 6 [3] => 7 [4] => 8 [5] => 10 [6] => 11 [7] => 12 [8] => 13 [9] => 14 ) The output of: print_r($array2); is simply: 1 Any idea as to why it would not only not shuffle the array, but knock off the remaining 9 items in the array? thanks!

  I have a .NET solution with a couple of projects. The output is a WPF application. Now I would like to put my binary resources (images/icons) in a single project/assembly in this solution, so that all my other projects in can use them. My question is how I can do that?

• JSF actionListener is called multiple times from within HtmlTable

  - by Rose

  I have a mix of columns in my htmltable: 1 column is an actionlistener, 2 columns are actions and other columns are simple output. <h:dataTable styleClass="table" id="orderTable" value="#{table.dataModel}" var="anOrder" binding="#{table.dataTable}" rows="#{table.rows}" <an:listenerColumn backingBean="${orderEntry}" entity="${anOrder}" actionListener="closeOrder"/ <an:column label="#{msg.hdr_orderStatus}" entity="#{anOrder}" propertyName="orderStatus" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="editOrder" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="viewOrder"/ .... I'm using custom tags, but it's the same behavior if I use the default column tags. I've noticed a very strange effect: when clicking the actionlistenercolumn, the actionevent is handled 3 times. If I remove the 2 action columns then the actionevent is handled only once. The managed bean has sessionscope, bean method: public void closeOrder(ActionEvent event) { OrdersDto order; if ((order = orderRow()) == null) { return; } System.out.println("closeOrder() 1 "); orderManager.closeOrder(); System.out.println("closeOrder() 2 "); } the console prints the'debug' text 3 times.

Any idea what could be wrong here? I want to stop any previous sound before playing current.

• How to do steps of an API through CLI/ batch mode without GUI

  - by Dolphin

  I'm using Audiveris API to generate xml(MusicXML) file once the sheetmusic(e.g. pdf/img file) is being input (i.e. When I give the sheet music (pdf file) location, to generate the xml file out of it (in another location)). Audiveris has its own GUI to do this. But can I do this process of sheetmusic-to-xml without using their GUI, but only from the CLI? If so how may I approach it? And also if so - is there a possibility to make it work in CLI - using Java code (say to invoke steps for API to occur in the CLI using Java Code - I've heard this is possible using shell commands)? I managed to open the GUI by opening the jar file from CLI. But I need to know whether there's a possibility to carry out the entire sheetmusic(say pdf)-to-xml process without using their GUI, but only through CLI (i.e. in batch mode)? Greatly appreciate any help or guidance Thanks in advance
