• Versioned cloud-based social code snippet management

  - by Chapso

  It seems a lot to ask, but I'm looking for a cloud-based solution to managing code snippets. I am looking for: Tags User accounts (I want to be able to see all of my snippets on a single page) syntax highlighting versioning - myself or others should be able to edit my snippets to improve them\ straightforward UI with minimal advertising if any Does anyone know of a solution which meets these requirements? If not, would anyone be interested in something like this? As a software engineer, after step zero (does it already exist), I'm perfectly willing to go onto step 1 (would other people use it? If so, make it).

• C++ and C#, "Casting" Functions to Delegates, What's the scoop?

  - by Jacob G

  In C# 2.0, I can do the following: public class MyClass { delegate void MyDelegate(int myParam); public MyClass(OtherObject obj) { //THIS IS THE IMPORTANT PART obj.SomeCollection.Add((MyDelegate)MyFunction); } private void MyFunction(int myParam); { //... } } Trying to implement the same thing in C++, it appears I have to do: MyDelegate del = gcnew MyDelegate(this, MyFunction); obj-SomeCollection-Add(del); Obviously I can create a new instance of the delegate in C# as well instead of what's going on up there. Is there some kind of magic going on in the C# world that doesn't exist in C++ that allows that cast to work? Some kind of magic anonymous delegate? Thanks.

• How do I stack Plack authentication handlers?

  - by Schwern

  I would like to have my Plack app try several different means of authorizing the user. Specifically, check if the user is already authorized via a session cookie, then check for Digest authentication and then fall back to Basic. I figured I could just enable a bunch of Auth handlers in the order I wanted them to be checked (Session, Digest, Basic). Unfortunately, the way that Plack::Middleware::Auth::Digest and Plack::Middleware::Auth::Basic are written they both return 401 if digest or basic auth doesn't exist, respectively. How is this normally dealt with in Plack?

• Security of PHP script, embedded or otherwise

  - by typoknig

  Hi all, I am curious about the security of PHP on an HTML webpage where PHP code is embedded (a webpage that would exist on the server as "webpage.php") or on a PHP script that may be referenced by an HTML page (that is, a PHP script that is not actually part of a webpage that exists on the server as "something.php" and is referenced by "webpage.html"). Getting to the point, let us say that if the source code of my PHP script is known by anyone it would be a very big problem. I know that when you view the source of a PHP page in a browser the PHP script is not shown, but what if the PHP server failed and the HTML still loaded (is this even possible), would a user be able to see the PHP script? To be more general, is there ANY possible way that a user could access the source of a PHP script from a web browser, and if so, how do I prevent it?

• Resizing JPanel to prepare for printing without removing it from its original position

  - by Lesman

  In my program I frequently need to print various JComponents (generally JPanels) and I like them to be full-page. The way I do it now is by using the following code: g2d.scale(pf.getImageableWidth()/componentToPrint.getWidth(), pf.getImageableHeight()/componentToPrint.getHeight()); but this often stretches or otherwise deforms whatever I am trying to print, and I would much prefer to do something that re-sized intelligently, perhaps a functional version of: componentToPrint.setSize(pf.ImageableWidth(), pf.ImageableHeight); or say adding the component into a new JFrame and then setting the frame size (problem is components can't exist in two place at once). I wouldn't care if the resizing would make the rest of the GUI look terrible, as long as it is something that can easily be reset. Is there any way to do this?

• FileNotFoundException when cropping a photo

  - by James G

  I'm trying to crop a photo to use in a Live Wallpaper but I'm getting a FileNotFoundException when the crop activity tries to save my new cropped image. This is the code I'm using: File file = new File(getFilesDir(), "wallpaper.jpg"); Intent intent = new Intent("com.android.camera.action.CROP"); intent.setData(uri); DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); intent.putExtra("outputX", metrics.widthPixels * 2); intent.putExtra("outputY", metrics.heightPixels); intent.putExtra("aspectX", metrics.widthPixels * 2); intent.putExtra("aspectY", metrics.heightPixels); intent.putExtra("scale", true); intent.putExtra("noFaceDetection", true); intent.putExtra("output", Uri.parse("file:/" + file.getAbsolutePath())); startActivityForResult(intent, REQUEST_CROP_IMAGE); The wallpaper.jpg file seems to exist on DDMS file explorer so I'm not sure what I'm doing wrong. Any advice is greatly appreciated.

• importing data using get or create - identity error 1062

  - by hamackey

  I am importing data from a mssql database into mysql. Works except when it encounters the id of a previous entry. id is unique. I need to get entries that already exist so that they can be placed in the work of the day. Error is IntegrityError: (1062, "Duplicate entry '001355338' for key 2") This entry is already in the database. I need it entered for that day, but can not have it added to the table. It is already there. def handle(self, *args, **options): 59 #patients_local = Patient.objects.all() 60 #attendings_local = Attending.objects.all() 61 connection = pyodbc.connect("XXXXXXXXXXX") 62 cursor = connection.cursor() 63 cursor.execute(COMMAND) 64 rows = cursor.fetchall() 65 for row in rows: 66 # get_or_create returns (object, boolean) 67 p, created = Patient.objects.get_or_create( 68 first_name = row.Firstname, 69 middle_name = '', 70 last_name = row.Lastname, 71 id = row.id, 72 )

• Using content from the project in tests

  - by oillio

  I am working with Visual Studio 2010 and it's integrated testing functionality. I have an XML file in my project which is set to copy to the output directory. I can access the file just fine when I compile and run the project. But it doesn't exist when I attempt to access it within a TestMethod. It looks like the test is run with the working directory set to an "Out" directory created within the TestResults directory. I can set a breakpoint before I use the file. If I then copy the file into this "Out" directory and continue running the test it accesses the file properly. But that is not really how I want my automated tests to function. Is it possible to tell VS to copy the build directory into this working directory?

• Does anyone else think instance variables are problematic in database-backed applications?

  - by Ben Aston

  It occurs to me that state control in languages like C# is not well supported. By this, I mean, it is left upto the programmer to manage the state of in-memory objects. A common use-case is that instance variables in the domain-model are copies of information residing in persistent storage (i.e. the database). Clearly this violates the single point of authority principle, and "synchronisation" has to be managed by the developer. I envisage a system where instead of instance variables, we have simple public access/mutator methods marked with attributes that link them to the database, and where reads and writes are mediated by a framework that decides whether to hit the database. Does such a system exist? Am I completely missing the point, or is there some truth to this idea?

• Rails group validation with just one error message

  - by Victor

  The following validation code in the model: validates :formatted_address, :zip, :city, :state, :country, :presence => true, :message => "is incomplete. Please enter full address." is displayed when either of the fields are empty. Let's say now :address and country are empty, 2 errors are displayed: Formatted Address is incomplete. Please enter full address. Country is incomplete. Please enter full address. How can I group the error message in the validation to just show one error message if either of the fields validated does not exist? Address is incomplete. Please enter full address. Thanks.

• Erlang Edoc in Emacs

  - by Roberto Aloi

  Let's say that I have an Erlang function, with spec. -spec foo(integer(), string()) -> boolean(). foo(_Integer, _String) -> true. My dream would be to generate the edoc from this information within Emacs automatically. The generated code should look like: %%-------------------------------------------------------------------- %% @doc %% Your description goes here %% @spec foo(_Integer::integer(), _String::string()) -> %%% boolean() %% @end %%-------------------------------------------------------------------- -spec foo(integer(), string()) -> boolean(). foo(_Integer, _String) -> true. Does a similar feature already exist?

• Asp.net MVC database connection setting in Visual studio 2008

  - by AK47

  I am trying to learn Asp.net MVC framework. I was looking at the video tutorial at the link below http://www.asp.net/learn/mvc-videos/video-395.aspx In this video the very first step is to add a new database to the example application. I have visual studio installed on my development machine but the SqlServer Express is running on a different machine, so when I try and add a new database following the same steps as the video I get the following error "Connections to SQL Server files(*.mdf) require SQL express 2005 to funciton properly. Please verify the installation of the component or download from the url" I am assuming this is because Visual studio is looking for an instance of SQL express on my local machine and since it doesnt exist on the local machine,it errors out. So how do i tell visual studio, to connect to a different machine and create the database there? I am using Visual studio 2008 with .net 3.5 Sp1

• Best directory to store application data with read\write rights for all users?

  - by Wodzu

  Hi guys. Until Windows Vista I was saving my application data into the directory where the program was located. The most common place was "C:\Program Files\MyApplication". As we know, under Vista and later the common user does't have rights to write under "Program Files" folder. So my first idea was to save the application data under "All Useres\Application Data" folder. But it seams that this folder has writing restrictions too! So to sum up, my requirements are: Folder should exist under Windows XP and above Microsoft's systems. All useres of the system should read\write\creation rights to this folder and it subfolders and files. I want to have only one copy of file\files for all useres. Thanks for your time.

• How to launch a program as as a normal user from a UAC elevated installer

  - by KZ

  I'm writing an NSIS installer and the setup program elevates "as administrator" as needed on Windows 7 / vista. I need to run the installed program at the end of the install and don't want to launch it with the same privileges as the installer. The regular NSIS exec commands run the child process with the same permissions as the installer. There is a UAC plugin for NSIS, but the documentation on it isn't great and it seems v. new; I'd prefer not to use that plugin. Ideally, I'm looking for a small .exe I can include that'll launch the target program without UAC elevation. Does this exist? Any other suggestions? Thanks!

• C# compile error for simple Annual Salary Calculator

  - by Mike Vignapiano

  I am new to C# and trying to create my 1st app. I have 3 errors. The first two say that txtSalary and Salary do not exist. The 3rd says that it cannot convert method group 'ToString' to non-delegate type 'string'. and asks if I intend to invoke the method. Here is what I have: protected void Button1_Click(object sender, EventArgs e) { int salary, AnnualHours, Rate; string txtAnnualHours, txtSalary, txtRate; salary = AnnualHours * Rate; txtsalary = int.Parse(Salary); txtAnnualHours = salary.ToString; MessageBox.Show(salary); } According to my book, when you enter numerics in AnnualHours and Rate textbox, when click Button1, these values are converted from string to integers, then multiplied for salary. Then numeric answer converted to string and displayed in messagebox named txtSalary. Please show me what I got wrong because according to the book, I am not missing anything.

• asp.net mvc. Inserting string data from model into javascript. best-practice

  - by Andrew Florko

  Hello everybody, I have to populate javascript code in html layout (hidden fields, method params) with string data from model. Html.Encode is not appropriate for my task because it encodes ' symbol, bypass : (that ruines object attributes declaration) and so on. I wrote static helper class that is used from View like this: alert('<%=ViewHelper.MakeJavaScriptSafe(Model.Message)%>'); I hope there is asp.net in-built function I don't know about for this task. Does it exist really? Thank you in advance.

• Django: Why Doesn't the Current URL Match any Patterns in urls.py

  - by austin_sherron

  I've found a few questions here related to my issue, but I haven't found anything that has helped me resolve my issue. I'm using Python 2.7.5 and Django 1.8.dev20140627143448. I have a view that's interacting with my database to delete objects, and it takes two arguments in addition to a request: def delete_data_item(request, dataclass_id, dataitem_id): form = AddDataItemForm(request.POST) data_set = get_object_or_404(DataClass, pk=dataclass_id) context = {'data_set': data_set, 'form': form} data_item = get_object_or_404(DataItem, pk=dataitem_id) data_item.delete() data_set.save() return HttpResponseRedirect(reverse('detail', args=(dataclass_id,))) The URL in myapp.urls.py looks something like this: url(r'^(?P<dataclass_id>[0-9]+)/(?P<dataitem_id>[0-9]+)/delete_data_item/$', views.delete_data_item, name='delete_data_item') and the portion of my template relevant to the view is: <a href="{% url 'delete_data_item' data_set.id data_item.id %}">DELETE</a> Whenever I click on the DELETE link, django tells me that the request URL: http://127.0.0.1:8000/myapp/5/%7B%%20url%20'delete_data_item'%20data_set.id%20data_item.id%20%%7D doesn't match any of my URL patterns. What am I missing? The URL on which the DELETE links exist is myapp/(<dataclass_id>[0-9]+)/

• small string optimization for vector?

  - by BuschnicK

  I know several (all?) STL implementations implement a "small string" optimization where instead of storing the usual 3 pointers for begin, end and capacity a string will store the actual character data in the memory used for the pointers if sizeof(characters) <= sizeof(pointers). I am in a situation where I have lots of small vectors with an element size <= sizeof(pointer). I cannot use fixed size arrays, since the vectors need to be able to resize dynamically and may potentially grow quite large. However, the median (not mean) size of the vectors will only be 4-12 bytes. So a "small string" optimization adapted to vectors would be quite useful to me. Does such a thing exist? I'm thinking about rolling my own by simply brute force converting a vector to a string, i.e. providing a vector interface to a string. Good idea?

• Deactivate any calls to Log before publishing: are there tools to do this?

  - by Nicolas Raoul

  According to Google, I must "Deactivate any calls to Log methods in the source code" before publishing my Android app (section 4 of the publication checklist). My open-source project is large and it is a pain to do it manually every time I release. Additionally, removing a Log line is potentially tricky, for instance: if(condition) Log.d(LOG_TAG, "Something"); data.load(); data.show(); If I comment the Log line, then the condition applies to the next line, and chances are load() is not called. Are such situations rare enough that I can decide it should exist? This is on the official checklist, so I guess many people do this on a regular basis. So, is there a tool that removes all Log lines? Preferably one that is not tricked by code like the above.

• JPA atomic query/save for multithreaded app

  - by TofuBeer

  I am in the midst of changing my JPA code around to make use of threads. I have a separate entity manager and transaction for each thread. What I used to have (for the single threaded environment) was code like: // get object from the entity manager X x = getObjectX(jpaQuery); if(x == null) { x = new X(); x.setVariable(foo); entityManager.persist(x); } With that code in the multi threaded environment I am getting duplicate keys since, I assume, getObjectX returns null for a thread, then that thread is swapped out, the next thread calls getObjextX, also getting null, and then both threads will create and persist a new X(). Short of adding in synchronization, is there an atomic way to get/save-if-doesn't-exist a value with JPA or should I rethink my approach EDIT: I am using the latest Eclipselink and MySql 5.1

• WM6x IMAPIAdviseSink::OnNotify threading issues

  - by violet313

  specifically WM6x, winCE5x Now my current understanding from trawling the msdn etal is that the IMAPIAdviseSink::OnNotify callback can be made from any old thread; from (ce)mapi or perhaps even from a third-party service provider. Under WM6x, i cannot seem to coax an in-thread response by invoking HrThisThreadAdviseSink, since while this function is declared in mapiutil.h, a definition appears not to exist (in cemapi.lib or wherever??) ~But i notice that all the OnNotify callbacks i receive derive from windows messages that i am receiving on my thread (=looks to me like an in-thread implementation in any case under cemapi)... So, can anyone confirm that this is infact always the case -or am i just getting lucky right now? ah, i should add that my advise source is IMAPISession::Advise erm i should also say that i might have cross-posted this on the msdn forum -but they're mostly numptys over there,,

• Bind Grid.Row / Grid.Column inside a DataTemplate

  - by Thorsten79

  Hope this is not a dupe. I would like to be able to do the following in XAML: <DataTemplate DataType="{x:Type NewGACCTestApp:ButtonVM}"> <Button Grid.Column="{Binding GridColumn}" Grid.Row="{Binding GridRow}" Content="{Binding Path=Info}" /> </DataTemplate> The Content binding works fine but Grid.Column and Grid.Row simply don't exist in the produced object. Not even when I set them to some value without binding (like in Grid.Column="1"). I've snooped the application and saw that inside my grid nobody ever sets Grid.Column and Grid.Row. Any ideas?
