• Visual Studio crashes when I add a .settings file in a C++ Windows form application

  - by Ant

  I'm trying to add a .settings file in a windows form application by adding a (whatever) file in the project and have it named smthng.settings. Right after it is created, it crashes (if I look into the project's directory the file is there, but it's not "in" the project). Am I doing it wrong or could it be that the problem lies elsewhere? Edit: It seems that it's the settings designer that crashes. Partially Solved:If I add a (whatever).config file, then rename it to .settings and change it's file type to C/C++ Code (don't ask how I figured this out..) then I can add to it settings, but if I do add something that has any connection to the form then automatically a (whatever).config with thew same name spawns (which is identical to the (whatever).setting even if change one of them) and at the stdafx.cpp a #include '(whatever).h' appears, which is a problem, because there is not such a header. (if I erase it or just create a blank (whatever).h it doesn't work. Apparently I have to somehow connect all the data in the (w/e).settings to (w/e).h as well or maybe something else) Anyone had this problem before? Anyone has any ideas?

• Program to format every media in c++

  - by AtoMerZ

  Problem: I'm trying to write a program that formats any type of media. So far I've managed to format Hard disk partitions, flash memories, SDRAM, RDX. But there's this last type of media (DVD-RAM) I need to format. My program fails to format this media. I'm using the FormatEx function in fmifs.dll. I had absolutely no idea how to use this function Except for its name and that it resides in fmifs.dll. with the help of this I managed to find a simple program that uses this library. Yet still it doesn't give complete information about how to use it. What I've tried: I'm looking for a full documentation about FormatEx, its parameters, and exactly what values each parameter can take. I tried searching on google and MSDN. This is what I found. First of all this isn't the function I'm working with. But even putting that aside there's not enough information on how to use the function (Like which headers/libraries to use). EDIT: I don't have to use FormatEx if there's an alternative to use please tell.

• xcode project-/target-settings-syntax for linker flag force_load on iPhone

  - by Kaiserludi

  Hi all. I am confronted with the double bind, that on the one hand for one of the 3rd party static libraries, my iPhone application uses, the linker flag -all_load has to be set in the application project- or target settings, otherwise the app crashes at runtime not finding some symbols, called internally from the lib, on the other hand for another 3rd party static lib -all_load must not be set on application level, or the app won't build thanks to a "duplicate symbols"-linker error. To solve this issue I now want to use force_load instant of load_all, as it due to documentation it does the same like all_load, but only for the passed path or lib-file, instead of all libs. The problem with force_load is, I do not have a clue, how to pass a path or file as parameter with it, when passing it via xcode project- or target-settings. All syntax-possibilities coming to my mind either lead into xcode thinking its another linker flag instead of a parameter to the previous one, or the linker is throwing syntax related errors or the flag simply does nothing at all in comparison to not being set. I also opened the .pbxproj-file in a text-editor to edit it to the correct command line syntax manually, but when reloading the project with xcode, it auto changes the syntax into interpreting the parameter to force_load as a separate flag. Anyone having an idea on this issue? Thx, Kaiserludi.

• How can I get vim to draw lines correctly for remote editing?

  - by Rick Reynolds

  I'm attempting to edit files on a remote system. I've ssh'd to the system and I start editing with vim. However, I notice that all the lines are drawing 2 lines above where they really exist in the file. I assumed this was a problem I could fix by dropping my terminal settings to something simpler, but that didn't help. My TERM variable was set to xterm-color. I set it to vt100, but that didn't fix the line drawing issue. I also noticed that this seems to be specific to vim. emacs doesn't show the problem, and I haven't noticed any odd drawing artifacts in less, more or other paging tools. Other specifics: I'm ssh-ing into the remote system from a Mac, using the Terminal.app. The remote system is running Ubuntu 9.04. I'm hoping there is something I just need to set in vim to get it to play nice. If it allows me to keep syntax color highlighting, so much the better.

• UnicodeEncodeError: 'ascii' codec can't encode character [...]

  - by user1461135

  I have read the HOWTO on Unicode from the official docs and a full, very detailed article as well. Still I don't get it why it throws me this error. Here is what I attempt: I open an XML file that contains chars out of ASCII range (but inside allowed XML range). I do that with cfg = codecs.open(filename, encoding='utf-8, mode='r') which runs fine. Looking at the string with repr() also shows me a unicode string. Now I go ahead and read that with parseString(cfg.read().encode('utf-8'). Of course, my XML file starts with this: <?xml version="1.0" encoding="utf-8"?>. Although I suppose it is not relevant, I also defined utf-8 for my python script, but since I am not writing unicode characters directly in it, this should not apply here. Same for the following line: from __future__ import unicode_literals which also is right at the beginning. Next thing I pass the generated Object to my own class where I read tags into variables like this: xmldata.getElementsByTagName(tagName)[0].firstChild.data and assign it to a variable in my class. Now what perfectly works are those commands (obj is an instance of the class): for element in obj: print element And this command does work as well: print obj.__repr__() I defined __iter__() to just yield every variable while __repr__() uses the typical printf stuff: "%s" % self.varname Both commands print perfectly and can output the unicode character. What does not work is this: print obj And now I am stuck because this throws the dreaded UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 47: So what am I missing? What am I doing wrong? I am looking for a general solution, I always want to handle strings as unicode, just to avoid any possible errors and write a compatible program. Edit: I also defined this: def __str__(self): return self.__repr__() def __unicode__(self): return self.__repr__() From documentation I got that this

• Writing a VM - well formed bytecode?

  - by David Titarenco

  Hi, I'm writing a virtual machine in C just for fun. Lame, I know, but luckily I'm on SO so hopefully no one will make fun :) I wrote a really quick'n'dirty VM that reads lines of (my own) ASM and does stuff. Right now, I only have 3 instructions: add, jmp, end. All is well and it's actually pretty cool being able to feed lines (doing it something like write_line(&prog[1], "jmp", regA, regB, 0); and then running the program: while (machine.code_pointer <= BOUNDS && DONE != true) { run_line(&prog[machine.cp]); } I'm using an opcode lookup table (which may not be efficient but it's elegant) in C and everything seems to be working OK. My question is more of a "best practices" question but I do think there's a correct answer to it. I'm making the VM able to read binary files (storing bytes in unsigned char[]) and execute bytecode. My question is: is it the VM's job to make sure the bytecode is well formed or is it just the compiler's job to make sure the binary file it spits out is well formed? I only ask this because what would happen if someone would edit a binary file and screw stuff up (delete arbitrary parts of it, etc). Clearly, the program would be buggy and probably not functional. Is this even the VM's problem? I'm sure that people much smarter than me have figured out solutions to these problems, I'm just curious what they are!

• Facebook IFrame Application issues for certain users

  - by Kon

  We have a strange issue with running an Facebook IFrame application (using MVC 2). When I run my app and log into Facebook, I get to the application just fine. But when my coworker does it, she gets the following error: API Error Code: 100 API Error Description: Invalid parameter Error Message: Requires valid next URL. Typically this error is resolved by updating the "New Data Permissions" setting of the Facebook application. However, in this case it doesn't help. We've also tried logging in with our accounts from different computers and it seems that neither computer nor which one the MVC ASP.NET app is running from matters. The only difference is who is logged into Facebook. We've looked at our Facebook account settings, but couldn't find any obvious differences. We both have Developer access to the FB application and we both can edit its settings. However, only one of us can actually run the application without getting the above mentioned error message. Any idea what could be happening here?

• Performance of VIEW vs. SQL statement

  - by Matt W.

  I have a query that goes something like the following: select <field list> from <table list> where <join conditions> and <condition list> and PrimaryKey in (select PrimaryKey from <table list> where <join list> and <condition list>) and PrimaryKey not in (select PrimaryKey from <table list> where <join list> and <condition list>) The sub-select queries both have multiple sub-select queries of their own that I'm not showing so as not to clutter the statement. One of the developers on my team thinks a view would be better. I disagree in that the SQL statement uses variables passed in by the program (based on the user's login Id). Are there any hard and fast rules on when a view should be used vs. using a SQL statement? What kind of performance gain issues are there in running SQL statements on their own against regular tables vs. against views. (Note that all the joins / where conditions are against indexed columns, so that shouldn't be an issue.) EDIT for clarification... Here's the query I'm working with: select obj_id from object where obj_id in( (select distinct(sec_id) from security where sec_type_id = 494 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) and sec_obj_id in ( select obj_id from object where obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) ) ) ) or (obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) and obj_id not in (select sec_obj_id from security where sec_type_id = 494) )

• Passing params in rails... Breakthrough in understanding params, aka, the "aha" moment

  - by Brian McDonough

  I have a simple has_many belongs_to relationship and I want to include the parent object for the view of the belongs_to model and I have had some success, but I want it to work better. class Submission < ActiveRecord::Base belongs_to :user belongs_to :contest end class Contest < ActiveRecord::Base belongs_to :user has_many :submissions, :dependent => :destroy end In the case that works, I pass contest_id to submissions by placing it in the url: <%= link_to 'Submit Contest Entry', new_submission_path(:contest_id => @contest.id), :class => 'btn btn-primary btn-large mleft10' %> So that, combined with a hidden_field: <%= f.hidden_field :contest_id %> And a find_contest method in the controller (called with a before_filter): def find_contest #the next line is giving the error (line 76) @contest = Contest.find(params[:submission][:contest_id]) end Makes it work for submissions/new, but how do I add a find to the controller that just works across more than that one page, like if I want to access in show and index. Right now, I get an error: Started GET "/submissions?contest_id=5" for 127.0.0.1 at 2012-12-01 16:01:45 -0800 Processing by SubmissionsController#index as HTML Parameters: {"contest_id"=>"5"} User Load (0.3ms) SELECT "users".* FROM "users" WHERE "users"."id" = 2 ORDER BY users.created_at DESC LIMIT 1 Completed 500 Internal Server Error in 37ms NoMethodError (undefined method `[]' for nil:NilClass): app/controllers/submissions_controller.rb:76:in `find_contest' [edited] Adding show action for submissions: before_filter :find_contest, :except => [:index, :show, :edit, :update, :destroy] def find_contest @contest = Contest.find(params[:submission][:contest_id]) end def show contest_id = @submission.contest_id @submission = @commentable = Submission.find(params[:id]) @comments = @commentable.comments.order(:created_at).reverse respond_to do |format| format.html # show.html.erb format.json { render :json => @submission } end end

• Sweave can't see a vector if run from a function ?

  - by PaulHurleyuk

  I have a function that sets a vector to a string, copies a Sweave document with a new name and then runs that Sweave. Inside the Sweave document I want to use the vector I set in the function, but it doesn't seem to see it. (Edit: I changed this function to use tempdir(() as suggested by Dirk) I created a sweave file test_sweave.rnw; % \documentclass[a4paper]{article} \usepackage[OT1]{fontenc} \usepackage{Sweave} \begin{document} \title{Test Sweave Document} \author{gb02413} \maketitle <<>>= ls() Sys.time() print(paste("The chosen study was ",chstud,sep="")) @ \end{document} and I have this function; onOK <- function(){ chstud<-"test" message(paste("Chosen Study is ",chstud,sep="")) newfile<-paste(chstud,"_report",sep="") mypath<-paste(tempdir(),"\\",sep="") setwd(mypath) message(paste("Copying test_sweave.Rnw to ",paste(mypath,newfile,".Rnw",sep=""),sep="")) file.copy("c:\\local\\test_sweave.Rnw", paste(mypath,newfile,".Rnw",sep=""), overwrite=TRUE) Sweave(paste(mypath,newfile,".Rnw",sep="")) require(tools) texi2dvi(file = paste(mypath,newfile,".tex",sep=""), pdf = TRUE) } If I run the code from the function directly, the resulting file has this output for ls(); > ls() [1] "chstud" "mypath" "newfile" "onOK" However If I call onOK() I get this output; > ls() [1] "onOK" and the print(...chstud...)) function generates an error. I suspect this is an environment problem, but I assumed because the call to Sweave occurs within the onOK function, it would be in the same enviroment, and would see all the objects created within the function. How can I get the Sweave process to see the chstud vector ? Thanks Paul.

• TinyMCE is glitchy/unusable in IE8

  - by Force Flow

  I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8? [edit]: stripping everything out of the init (leaving just script_url and theme) results in the same symptoms

• How to use Nhibernate Validator + NHib component + ddl

  - by mynkow

  I just configured my NHibValidator. My NHibernate creates the DB schema. When I set MaxLenght="20" to some property of a class then in the database the length appears in the database column. I am doing this in the NHibValidator xml file. But the problem is that I have components and cannot figure out how to achieve this behaviour. The component is configured correctly in the Customer.hbm.xml file. EDIT: Well, I found that Hibernate Validator users had the same problem two years ago. http://opensource.atlassian.com/projects/hibernate/browse/HV-25 Is this an issue for NHibernate Validator or it is fixed. If it is working tell me how please. ----------------------------------------------------- public class Customer { public virtual string Name{get;set;} public virtual Contact Contacts{ get; } } ----------------------------------------------------- public class Contact { public virtual string Address{get;set;} } ----------------------------------------------------- <?xml version="1.0" encoding="utf-8" ?> <nhv-mapping xmlns="urn:nhibernate-validator-1.0" namespace="MyNamespace" assembly="MyAssembly"> <class name="Customer"> <property name="Name"> <length max="20"/> </property> <property name="Contacts"> <notNull/> <valid/> </property> </class> </nhv-mapping> ----------------------------------------------------- <?xml version="1.0" encoding="utf-8" ?> <nhv-mapping xmlns="urn:nhibernate-validator-1.0" namespace="MyNamespace" assembly="MyAssembly"> <class name="Contact"> <property name="Address"> <length max="50"/> <valid/> </property> </class> </nhv-mapping> -----------------------------------------------------

• get_by_id method on Model classes in Google App Engine Datastore

  - by tarn

  I'm unable to workout how you can get objects from the Google App Engine Datastore using get_by_id. Here is the model from google.appengine.ext import db class Address(db.Model): description = db.StringProperty(multiline=True) latitude = db.FloatProperty() longitdue = db.FloatProperty() date = db.DateTimeProperty(auto_now_add=True) I can create them, put them, and retrieve them with gql. address = Address() address.description = self.request.get('name') address.latitude = float(self.request.get('latitude')) address.longitude = float(self.request.get('longitude')) address.put() A saved address has values for >> address.key() aglndWVzdGJvb2tyDQsSB0FkZHJlc3MYDQw >> address.key().id() 14 I can find them using the key from google.appengine.ext import db address = db.get('aglndWVzdGJvb2tyDQsSB0FkZHJlc3MYDQw') But can't find them by id >> from google.appengine.ext import db >> address = db.Model.get_by_id(14) The address is None, when I try >> Address.get_by_id(14) AttributeError: type object 'Address' has no attribute 'get_by_id' How can I find by id? EDIT: It turns out I'm an idiot and was trying find an Address Model in a function called Address. Thanks for your answers, I've marked Brandon as the correct answer as he got in first and demonstrated it should all work.

• PHP with Javascript: Email confirmation script not working

  - by Josh K

  Hey Heres what i got: echo "<script type=\"text/javascript\"> function finishForm() { var answer = confirm('Are you sure these are the teams you want to enter with?'); if (answer) { if(document.getElementByID(emailconfirm).value == ".$_SESSION[Email].") { form.action=\"esubmit.php\"; form.submit(); } else { alert('E-mail address do not match'); return false; } } } function restartForm() { var answer = confirm('Are you sure you want to start over?'); if (answer) { form.action=\"e1.php\"; form.submit(); } } </script>"; I have a regular button calling this function. emailconfirm is a text input. I want to confirm that they have chosen the right teams, then check if the email in the session and the email confirmation text match. If they do match Then i want to submit the form. If they dont match, I want to alert the user they dont match, and just return to page so user can check emails and then resubmit. This script is in my header. EDIT: Haha sorry i submitted one before and it didnt go through, forgot to add my problem!! When you click the button it comes up with the confirmation, clicking either yes or no doesnt do anything. The alert doesnt pop up if they dont match and if they do match it doesnt submit. Also it might be good to note I had it without the email confirmation if statement and it worked fine (going to the submit page)

• Concept of WNDCLASSEX, good programming habits and WndProc for system classes

  - by luiscubal

  I understand that the Windows API uses "classes", relying to the WNDCLASS/WNDCLASSEX structures. I have successfully gone through windows API Hello World applications and understand that this class is used by our own windows, but also by Windows core controls, such as "EDIT", "BUTTON", etc. I also understand that it is somehow related to WndProc(it allows me to define a function for it) Although I can find documentation about this class, I can't find anything explaining the concept. So far, the only thing I found about it was this: A Window Class has NOTHING to do with C++ classes. Which really doesn't help(it tells me what it isn't but doesn't tellme what it is). In fact, this only confuses me more, since I'd be tempted to associate WNDCLASSEX to C++ classes and think that "WNDCLASSEX" represents a control type . So, my first question is What is it? In second place, I understand that one can define a WndProc in a class. However, a window can also get messages from the child controls(or windows, or whatever they are called in the Windows API). How can this be? Finally, when is it a good programming practise to define a new class? Per application(for the main frame), per frame, one per control I define(if I create my own progress bar class, for example)? I know Java/Swing, C#/Windows.Form, C/GTK+ and C++/wxWidgets, so I'll probably understand comparisons with these toolkits.

• Subset and lagging list data structure R

  - by user1234440

  I have a list that is indexed like the following: >list.stuff [[1]] [[1]]$vector ... [[1]]$matrix .... [[1]]$vector [[2]] null [[3]] [[3]]$vector ... [[3]]$matrix .... [[3]]$vector . . . Each segment in the list is indexed according to another vector of indexes: >index.list 1, 3, 5, 10, 15 In list.stuff, only at each of the indexes 1,3,5,10,15 will there be 2 vectors and one matrix; everything else will be null like [[2]]. What I want to do is to lag like the lag.xts function so that whatever is stored in [[1]] will be pushed to [[3]] and the last one drops off. This also requires subsetting the list, if its possible. I was wondering if there exists some functions that handle list manipulation. My thinking is that for xts, a time series can be extracted based on an index you supply: xts.object[index,] #returns the rows 1,3,5,10,15 From here I can lag it with: lag.xts(xts.object[index,]) Any help would be appreciated thanks: EDIT: Here is a reproducible example: list.stuff<-list() vec<-c(1,2,3,4,5,6,7,8,9) vec2<-c(1,2,3,4,5,6,7,8,9) mat<-matrix(c(1,2,3,4,5,6,7,8),4,2) list.vec.mat<-list(vec=vec,mat=mat,vec2=vec2) ind<-c(2,4,6,8,10) for(i in ind){ list.stuff[[i]]<-list.vec.mat }

• Resharper 5: How do I set the default formatting style for inline code blocks?

  - by nukefusion

  I've got a problem with the formatting of inline code blocks within the VS2010 text editor and wonder if anyone else has had similar problems and found the 'magic' setting I'm looking for. I'm working my way through tutorials in an MVC book. Whenever I add some inline code blocks to a view I want them formatted like so: <% foreach (var link in Model) { %> <a href="<%=Url.RouteUrl(link.RouteValues)%>"> <%=link.Text%> </a> <% } %> What I'm actually getting is this (auto-formatted by the IDE when I finish writing the code): <% foreach (var link in Model) { %> <a href="<%=Url.RouteUrl(link.RouteValues)%>"> <%=link.Text%> </a> <% } %> It's pretty irritating. Any ideas on how I can instruct the IDE to leave my <% % tags alone? I've been fiddling with options under "Tools - Options - Text Editor" for ages but alas am getting nowhere... Edit: I've just noticed that this is down to Resharper 5 (when I disable it the problem disappears), however I still don't know how to stop it. Any ideas?

• jQuery UI sortable - sorting images

  - by GSTAR

  I've just implemented the jQuery UI sortable plugin for a set of images. The markup I have is as follows: <ul id="images" class="ui-sortable"> <li id="7884029"><img src="/images/member/4698568/7884029_t.jpg" alt="" /></li> <li id="7379458"><img src="/images/member/4698568/7379458_t.jpg" alt="" /></li> <li id="1704208"><img src="/images/member/4698568/1704208_t.jpg" alt="" /></li> <li id="1750715"><img src="/images/member/4698568/1750715_t.jpg" alt="" /></li> <li id="4364912"><img src="/images/member/4698568/4364912_t.png" alt="" /></li> </ul> <script type="text/javascript"> /*<![CDATA[*/ jQuery(function($) { jQuery('#images').sortable({'delay':'100'}); }); /*]]>*/ </script> The LI id is the 'name' column in the DB table - I prefer not to display the ID column. Now my question is how do I capture the sorting? I understand this would be an AJAX request but I have no idea how to do it. I have set up a sort_order column in my DB table and I am using PHP as my scripting language. I could do with a code example. EDIT: Ideally I prefer if the sort order is applied upon moving an item, i.e. I do not want to enclose it all in a form.

• File descriptor limits and default stack sizes

  - by Charles

  Where I work we build and distribute a library and a couple complex programs built on that library. All code is written in C and is available on most 'standard' systems like Windows, Linux, Aix, Solaris, Darwin. I started in the QA department and while running tests recently I have been reminded several times that I need to remember to set the file descriptor limits and default stack sizes higher or bad things will happen. This is particularly the case with Solaris and now Darwin. Now this is very strange to me because I am a believer in 0 required environment fiddling to make a product work. So I am wondering if there are times where this sort of requirement is a necessary evil, or if we are doing something wrong. Edit: Great comments that describe the problem and a little background. However I do not believe I worded the question well enough. Currently, we require customers, and hence, us the testers, to set these limits before running our code. We do not do this programatically. And this is not a situation where they MIGHT run out, under normal load our programs WILL run out and seg fault. So rewording the question, is requiring the customer to change these ulimit values to run our software to be expected on some platforms, ie, Solaris, Aix, or are we as a company making it to difficult for these users to get going? Bounty: I added a bounty to hopefully get a little more information on what other companies are doing to manage these limits. Can you set these pragmatically? Should we? Should our programs even be hitting these limits or could this be a sign that things might be a bit messy under the covers? That is really what I want to know, as a perfectionist a seemingly dirty program really bugs me.

• WPF: How to bind and update display with DataContext

  - by Am

  I'm trying to do the following thing: I have a TabControl with several tabs. Each TabControlItem.Content points to PersonDetails which is a UserControl Each BookDetails has a dependency property called IsEditMode I want a control outside of the TabControl , named ToggleEditButton, to be updated whenever the selected tab changes. I thought I could do this by changing the ToggleEditButton data context, by it doesn't seem to work (but I'm new to WPF so I might way off) The code changing the data context: private void tabControl1_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (e.Source is TabControl) { if (e.Source.Equals(tabControl1)) { if (tabControl1.SelectedItem is CloseableTabItem) { var tabItem = tabControl1.SelectedItem as CloseableTabItem; RibbonBook.DataContext = tabItem.Content as BookDetails; ribbonBar.SelectedTabItem = RibbonBook; } } } } The DependencyProperty under BookDetails: public static readonly DependencyProperty IsEditModeProperty = DependencyProperty.Register("IsEditMode", typeof (bool), typeof (BookDetails), new PropertyMetadata(true)); public bool IsEditMode { get { return (bool)GetValue(IsEditModeProperty); } set { SetValue(IsEditModeProperty, value); SetValue(IsViewModeProperty, !value); } } And the relevant XAML: <odc:RibbonTabItem Title="Book" Name="RibbonBook"> <odc:RibbonGroup Title="Details" Image="img/books2.png" IsDialogLauncherVisible="False"> <odc:RibbonToggleButton Content="Edit" Name="ToggleEditButton" odc:RibbonBar.MinSize="Medium" SmallImage="img/edit_16x16.png" LargeImage="img/edit_32x32.png" Click="Book_EditDetails" IsChecked="{Binding Path=IsEditMode, Mode=TwoWay}"/> ... There are two things I want to accomplish, Having the button reflect the IsEditMode for the visible tab, and have the button change the property value with no code behind (if posible) Any help would be greatly appriciated.

• rspec and ruby 1.9.1: problem with dummy controller and routes

  I want to test a module that basically executes some verify statements, to ensure that actions are invoked with the correct method. # /lib/rest_verification.rb module RestVerification def self.included(base) # :nodoc: base.extend(ClassMethods) end module ClassMethods def verify_rest_actions verify :method => :post, :only => [:create], :redirect_to => { :action => :new } ... end end end I tried this: describe RestVerification do class FooController < ActionController::Base include RestVerification verify_rest_actions def new ; end def index ; end def create ; end def edit ; end def update ; end def destroy ; end end # controller_name 'foo' # this only works with ruby 1.8.7 : 1.9.1 says "uninitialized constant FooController" tests FooController # this works with both before(:each) do ActionController::Routing::Routes.draw do |map| map.resources :foo end end after(:each) do ActionController::Routing::Routes.reload! end it ':create should redirect to :new if invoked with wrong verb' do [:get, :put, :delete].each do |verb| send verb, :create response.should redirect_to(new_foo_url) end end ... end When testing: $ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux] $ rake RestVerification :create should redirect to :new if invoked with wrong verb Finished in 0.175586 seconds $ rvm use 1.9.1 Using ruby 1.9.1 p378 $ rake RestVerification :create should redirect to :new if invoked with wrong verb (FAILED - 1) 1) 'RestVerification :create should redirect to :new if invoked with wrong verb' FAILED expected redirect to "http://test.host/foo/new", got redirect to "http://test.host/spec/rails/example/controller_example_group/subclass_1/foo/new" Is this a known issue? Is there a workaround?

• Why the HelloWorld of opennlp library works fine on Java but doesn't work with Jruby?

• How to only fade content once it is ready in Jquery?

  - by Jared

  Hello, I've seen examples for load() and ready(), but they always seem to apply to the window or document body, or a div or img or something like that. I have a hover() function, and when you hover over it, it uses fadeIn() to reveal it. Problem is, the images inside the div aren't loaded yet, so it ends up just appearing anyway. I need code that will only allow the image to fade when it's contents are fully loaded. When I just plug in other selectors like the following, it doesn't work $(this).next(".menuPopup").ready(function () { //or load(), neither work fadeTo(300, 1); }); EDIT: Relevant code $( '.leftMenuProductButton' ).hover ( function () { $(this).next(".menuPopup").stop().css("opacity", 1).fadeIn('slow'); }, function () { $(this).next(".menuPopup").stop().hide(); }); HTML <div class="leftMenuProductButton"> Product 1</div> <div id="raceramps56" class="menuPopup"><IMG SRC="myimage.jpeg"> </div>
