• Tree View / File View Control for C#

  - by Jason

  I have been looking for a C# tree control for displaying a file system that has the following capabilities: Select a starting directory. I don't always want to start at a "default" top directory level. The ability to grab an event when the user double clicks on a file in the tree. I want to handle opening the file within my application. I have been looking at this C# File Browser. Unfortunately, I have not been able to figure out how to do meet my second need. (If anybody can clear that up for me, I would like that even better.) Thanks for any help.

• Flatten old history in Git

  - by schoetbi

  I have a git project that has run for a while and now I want to throw away the old history, say from start to two years back from now. With throw away I mean replace the many commits within this time with one single commit doing the same. I checked "git rebase -i " but this does not remove the other (full) history containing all commits from git. Here a graphical representation (d being the changesets): (base) -> d1 -> d2 -> d3 -> (HEAD) What I want is: (base,d1,d2) -> d3 -> (HEAD) How could this be done? Thanks.

• Examine one particular call and ignore the rest

  - by lulalala

  I have a Currency class and want to update its rates. The following is the spec of an update class I plan to write: describe WebCrawlers::Currency::FeedParser do let(:gbp){ double('GBP').as_null_object } let(:usd){ double('USD').as_null_object } describe '#perform' do before do Currency.stub(:find_by_name).with('GBP').and_return( gbp ) Currency.stub(:find_by_name).with('USD').and_return( usd ) end it 'should update GBP rate' do gbp.should_receive(:update_attributes).with(rate_to_usd:0.63114) subject.perform end it 'should not update USD rate' do usd.should_not_receive(:update_attributes) subject.perform end end end and it works find if I only update GBP in my actual class: class WebCrawlers::Currency::FeedParser def perform Currency.find_by_name('GBP').update_attributes(rate_to_usd: 0.63114) end end However once I start updating other currencies like 'CAD', Rspec complains <Currency> received :find_by_name with unexpected arguments expected: ("USD") got: ("CAD") Why is this the case? Instead of NOT expecting USD, it says it is. And in the future there will be lots of currencies to update, but I don't want to test and stub each one of them. How can I resolve this issue?

• How to run shell script with live feedback from PHP?

  - by Highway of Life

  How would I execute a shell script from PHP while giving constant/live feedback to the browser? I understand from the system function documentation: The system() call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a server module. I'm not clear on what they mean by running it as a 'server module'. I attempted to run the script in the cgi-bin, but either I'm doing it wrong, or that's not what they mean. Example PHP code: <?php system('/var/lib/script_test.sh'); Example shell code: #!/bin/bash echo "Start..." for i in {1..10} do echo "$i..." sleep 1 done echo "Done."

• How to change TextView background color when touching in and out of view?

  - by MikeShiny

  This has to be a very simple fix, but I can't seem to figure it out. I have got my program to change the background color to change onClick, and onTouch with ACTION_DOWN and ACTION_UP. But I need it to change the color when touching the screen and going in and out of the TextView. I need it to function like a mouseOver/mouseOut event. Is there a way to do this on android? Or am I stuck with onTouch, where the action has to start from within the TextView? Right now I set the onTouch Listener on the textview itself. Should I set it somewhere else and then check if the x and y are within the Textview? Or is there another event listener I should be using? I am new to Android, any help would be appreciated. Thanks. Mike

• How do I do a fresh install of Google App Engine?

  - by ryan

  I've been using GAE for months now, but very recently I've had difficulty getting the latest release (1.3.4) to work for me. I'd like to remove GAE and start from scratch and reinstall it. However, it appears that deleting the googleappenginelauncher.app is not enough to completely remove it, because when I install the launcher again I see that it remembers the applications it was running previously (so at a minimum, there are some config files out there that I'm not removing properly). I'm new to Macs, so if there are other things I need to do besides deleting the .app, please let me know. Thanks for your help!

• chapters in videos for the iPhone

  - by Grégoire Cachet

  Is it possible to use chapters in videos for the iPhone in an application? For example: I have a 3 minutes video to play. I have chapter 1 starting at 0s, chapter 2 at 50s, chapter 3 at 95s. Can I start plating the video at 50s (chapter 2) until the end? Can I make it play just the chapter 2 from 50s to 95s? My question is not about how to add chapters to a video. I want to know if this behaviour is available on the iphone.

• Resharper: how to force introducing new private fields at the bottom of the class?

  - by Igor Brejc

  Resharper offers a very useful introduce and initialize field xxx action when you specify a new parameter in a constructor like: Constructor (int parameter) The only (minor) nuisance is that it puts the new field at the beginning of the class - and I'm a fan of putting private parts as far away as possible from the prying eyes of strangers ;). If, however, you already have some private fields in the class, Resharper will put the new field "correctly" (note the quotes, I don't want to start a flame war over this issue) next to those, even if they are at the end of the class. Is there a way to force Resharper to always put new fields at the end of the class? UPDATE: OK, I forgot to mention I know about the "Type Members Layout in Options" feature, but some concrete help on how to modify the template to achieve fields placement would be nice.

• discrepancy in using AsyncTask, code is executed in weird order

  - by Pentium10

  Hello, In onCreate method I hav the following order of code objItem = new DbClass(this);//the onCreate event creates the database new PrepareAdapter1().execute();//this task uses the tables, but SQLException occures, tables doesn't exists As you see in my short code, I get a new instance of the SQLiteOpenHelper class, which does create the tables in onCreate. And after that I start an AsyncTask instance where I use the created table. But I get SQLiteException as table doesn't not exists. I am using this code in wrong way? I expect the table to be created when I launch the thread.

  Please imagine this small database... Diagram Tables Volunteer Event Shift EventVolunteer ========= ===== ===== ============== Id Id Id EventId Name Name EventId VolunteerId Email Location VolunteerId Phone Day Description Comment Description Start End Associations Volunteers may sign up for multiple events.

A volunteer may staff multiple shifts. Check Constraints Can I create a check constraint to enforce that no shift is staffed by a volunteer that's not signed up for that shift's event? Can I create a check constraint to enforce that two overlapping shifts are never staffed by the same volunteer?

• help with installing clamav for remote apache server vs WAMP localserver

  - by Scarface

  Hey guys, I have never installed an extension before so I am not really sure where to start. I want to do 2 things: install clamav virus scanner http://sourceforge.net/projects/php-clamav/ on my remote server which is a linux apache setup using cpanel as a gui. install clamav on my localserver on my home computer which operates on windows and has WAMP server installed for server-side activity What is the difference between the two installation methods? What is required for each installation? If anyone can point me in the right direction in any way, I would really appreciate it. Even if it is just an article or tutorial on how to get started.

• jQuery UI Draggable 'stop' event called too many times?

  - by Graham

  I have a feeling I'm either misunderstanding the 'stop' event or not doing it right, but it seems to be called several times while the element is bound to is being dragged. makeAllDragable = function () { $(".test-table").draggable({ start: function (event, ui) { $(this).click(); }, stop: function (event, ui) { foo() } }).click(function () { selectTable($(this)); }); } foo = function () { alert("test"); } In this example foo is called about 30 times, shouldn't is just be when I release the draggable? The jQuery docs don't actually say one where or another though.

• Playing Ogg Sound in Android

  - by baba tenor

  In my application, I am trying to play a sound file in ogg format, stored in raw folder in res directory of my application. When I press the button that calls below function, it just freezes with the button pressed and does not respond. In the end, I have to terminate the application from Eclipse. Nothing about an error or exception in Logcat. In debugging mode, it enters create function and never comes back. What am I doing wrong? private void playbeep() { mPlayer = MediaPlayer.create(this, R.raw.beep); mPlayer.start(); mPlayer.release(); }

• Sprint to the finish: how to keep all team-members busy in the final days of a Scrum sprint?

  - by sdg

  Given that the tasks in a specific sprint will not divide perfectly into the team, and all finish on the same date, what do you do to keep everyone working as the sprint moves into its final stages? Inevitably it seems like there will be one or two people freed-up. If all the other tasks are done-done, and the remaining tasks are already underway, then what? Do those team-members pick up items from the top of the product backlog, as they are likely to be needed in the next sprint anyways to get a head start? What do you or your teams do?

• REST client website login

  - by Jordan

  I have written a REST service that uses WSSE as an authentication method but i want to be able to use this rest service through a browser by creating a website around the service. I want the user to be able to log in on the website then when they view, for example the "view users" page an ajax request is made to test.com/users and back comes the list. The part i'm trying to get my head around is the logging in/out on the website and keeping the user logged in across pages. Since in a true REST implementation there's no state held on the server, i can't use $_SESSION and now i don't know where to start! What is the best way to go about this? Do i still need to store session information on the server then possibly use cURL to make the request? Thanks Jay

• Magento - Mage::getModel not working on remote server

  - by Diego

  I'm struggling with an issue for which I can't find an explanation. I have two development environments that I use for my projects. I created a simple module for Magento and I tested it on one environment. After overcoming all Magento's complications, the module works as expected. This is on XAMPP. I then copied the module to the development Linux environment, on a hosted server, and it crashes miserably. I did some debugging, and I found out that a call to Mage::getModel() returns bool(false) instead of the instance of the Model I requested. I double checked all files and directories, and they match. Database is not involved (not from my side, at least, I don't need tables) and both environments have only me as a User, with Admin permissions. Any suggestion on where should I start looking is welcome, thanks.

• ant support for dynamic target

  - by Li He

  I previous saw some similar questions on stackoverflow but didn't see any solution. I guess the answer could be impossible and I am trying to see who can provide me this confirmation. AFAIK, an ant project contains several targets and each target may have several tasks. There is an task MacroDef that defines a sequential of `things' (tasks I suppose?). I tried to put target inside this block but ant complains the name of the target is missing (I am using the attribute of the macrodef to generate the name of the target). So it could be a dead end. Then I found that by using a task `script', we have access to the Project and can even call addTarget/AddOrReplaceTarget from there. But it seems that the targets I create there have no impact on the running targets. Does that mean ant doesn't support manipulating dependencies at target runtime? Is there any way to generate these targets before ant start building the dependency graph?

• Transfer Core Data from One Project to Another

  - by Michael

  The answer is probably a resounding 'NO' but before I start a new project from scratch, I thought I'd ask. I create many throw away projects to test ideas and code before combining all the successful bits from the scratch projects into a final version. So I have one project with the Core Data stuff worked out but I want to move it to a new project. My guess is that there is too many internal hooks and dropping in the .xcdatamodel and the sqlite db is just not going to work. I'd glad to be wrong...

• Sinatra Set Settings (Ruby)

  - by JP

  Using Sinatra in Ruby you can set the server's settings by doing: set :myvariable, "MyValue" and then access it anywhere in templates etc with settings.myvariable. In my script I need to be able to re-set these variables falling back to a bunch of defaults. I figured the easiest way to do this would be to have a function that performs all the sets calling it at the start of the Sinatra server and when I need to make the alterations: class MyApp < Sinatra::Application helpers do def set_settings s = settings_from_yaml() set :myvariable, s['MyVariable'] || "default" end end # Here I would expect to be able to do: set_settings() # But the function isn't found! get '/my_path' do if things_go_right set_settings end end # Etc end As explained in the code above, the set_settings function isn't found, am I going about this the wrong way?
