21,140,590 | 0 | Dynamic INSERT Statement in Python <p>I am working on updating some Python code I have been working with and was looking for some advice on the best way to deal with an idea I am working with. The part of my code that I wish to change is :</p> <pre><code>my_reader = csv.reader(input, delimiter = ',',quotechar='|') mouse.executemany("INSERT INTO Example_Input (ID,Name,Job,Salary) VALUES (?,?,?,?)", my_reader) </code></pre> <p>The code works. My question is, can I change the "(?,?,?,?)" into something more dynamic like 'range()' to allow user input. I understand that I would also have to have a dynamic create table statement, so another solution might be to count the number of inputs. </p> <p>To be a little more clear: for example if I had raw_input("How many variables does the table contain?: ") and the input was 2, the program would know to run as if (?,?).</p> <p>Thoughts?</p> <p>(also I am using SQLite3 and python 2.7)</p> |

You could use <code>diff</code> to compare what's in those files between the system. However, that's just the network stuff (static v.s. dynamic, routes, gateways, iptables firewalls, blah blah blah).

673,607 | 0 | <p>According to the <a href="http://msdn.microsoft.com/en-us/library/aa260631(SQL.80).aspx" rel="nofollow noreferrer">documentation</a>, the Transact-SQL <strong>timestamp</strong> data type is just an incrementing number and does not preserve a date or a time. You can't convert that to a meaningful <code>DateTime</code> value.</p> <p>The documentation says that it's an 8-byte value. So, if it's stored in a <code>System.Data.Linq.Binary</code>, you could convert it to a <code>long</code> with this code:</p> <pre><code>System.Data.Linq.Binary timestampValue; // Somehow get a reference to the SQL timestamp you're interested in // Use BitConverter to convert the 8 bytes to a long long timestampLong = BitConverter.ToInt64(timestampValue.ToArray(), 0); </code></pre> <p>You could try to convert that value to a <code>DateTime</code> by calling the constructor that takes a <code>ticks</code> value, but the results would be meaningless. You might also encounter an exception if the <code>ticks</code> value is out of range.</p> |

20,611,140 | 0 | Use object from DLL instead of WebProxy in amsx web service <p>I have a solution with two projects in VS2012. One is an old ASMX web service project and one is a DLL project called Utils.</p> <p>The Web Service project makes alot of use of the Utils project and the idea is that this DLL will also be shipped to clients because they will need functionality from it as well.</p> <p>So a <code>WebMethod</code> in the Web Service project looks like this:</p> <pre><code>using Utils; [WebMethod] [XmlType(Namespace = "http://url/invoice")] public void CheckInvoice(CToken token) { ... } </code></pre> <p>So in this example the Web Method <code>CheckInvoice</code> expects an instance of class <code>CToken</code>, which is in the <code>Utils</code> namespace.</p> <p>But when i generate the proxy class of the Web Service, then the exposed method <code>CheckInvoice</code> expects a <code>CToken</code> instance from the <code>ServiceProxy</code> namespace instead of the <code>Utils</code> namespace.</p> <p>But the clients also have the <code>Utils</code> DLL. So how can i force generation of the proxy to use the <code>CToken</code> class from the <code>Utils</code> namespace and not from the (default) ServiceProxy namespace?</p> <p>--</p> <p>When i add the <code>Service Reference</code> then i checked the <strong><em>Reuse types in referenced assemblies</em></strong> checkbox and also <strong><em>Reuse types in all referenced assemblies</em></strong>.

4,252,065 | 0 | If I'm trying to learn OpenGL ES 2.x, is an OpenGL 3.0 book suitable? <p>I've been doing about an hour of research on this, coming from zero graphics experience. The official website says that OpenGL ES 2.x is defined relative to OpenGL 2.0. However, I've read that a major difference between 2.0/3.0 is the deprecation of the fixed-function pipeline (no idea what that is at this point), and that ES 2.x doesn't have a fixed-function pipeline. These last details are what's confusing me.</p> <p>The reason I'm asking is because I'm considering buying the <a href="http://rads.stackoverflow.com/amzn/click/0321712617" rel="nofollow">OpenGL Superbible 5th Edition</a>. According to the author and some Amazon reviewers, this book is heavily biased towards OpenGL 3.0, and it's actually recommended to get earlier editions for OpenGL 2.0. Considering that I'm mainly interested in ES, which OpenGL version is most relevant, 2.0 or 3.0?</p> <p>Also, if for some reason I decide to go with ES 1.1, I'm assuming a 2.0 book is the right choice?</p> |

21,274,132 | 0 | Produce an iCal appointment and subsequent updates via email but don't offer accept/decline options <p>We are writing a system that has a booking feature, and we are planning to have it send *.ics files via email to attendees so they can easily add appointments to their calendars. The types of events are things like training courses (e.g. 3pm in the boardroom).</p> <p>We've got this working to the point that the system sends the *.ics, and using Gmail and Outlook, the user can accept the appointment which, is then added to their calendar.</p> <p>Sometimes an event changes (e.g. a course is cancelled or delayed until the following day). Our software can send out a new *.ics file, and Gmail/Outlook correctly recognize that this is an update to the original appointment and gives the option to accept/decline again.</p> <p>The trouble is, we don't have a mechanism to receive via email the accept/decline responses that standard email clients automatically send when the user accepts/declines an appointment. Therefore, clicking the "decline" option could give them the false sense that they have cancelled the appointment when in fact our system has no idea what they've done within their calendar.</p> <p>We always want the bookings to be instigated by the user directly on the website, and the *.ics via email is merely a convenience to help them remember to attend. Similar to a flight booking, if the passenger really intends to cancel, something a little more definitive is required than clicking "decline" in Outlook. With a few flight bookings I've made, the carrier sent me a *.vcs file which contains "METHOD:PUBLISH" instead of "METHOD:REQUEST" which sounds closer to what we want, although in testing, this *.vcs file was not recognized by GMail as an appointment.</p> <p>So the question is, can we email appointments, with subsequent updates, that will be automatically be recognized by Outlook, GMail & Lotus Notes, but prevent the user from thinking they can cancel/decline the entire booking from within their own calendar tool? If so, how?</p> <p><strong>UPDATE 1</strong></p> <p>I think I found the issue with the METHOD:PUBLISH airline booking example I was experimenting with - it was for a past date. Using a future date, We can now use METHOD:PUBLISH to allow people to add events to their calendar without requiring accept/decline. Problem now is that if the event is cancelled or changed, we cannot get a new *.ics to be recognized as overriding the original. We are allocating a unique UID and incrementing the SEQUENCE field to the event, but I don't know whether the spec allows a "PUBLISH"-ed event to elegantly handle updates (date, time, location, description etc.)</p> <p><strong>UPDATE 2</strong></p> <p>Okay, well I've just been experimenting with the sample *.ics files from the <a href="http://tools.ietf.org/html/rfc5546" rel="nofollow">spec</a>. Using the examples from 4.1.1 "A Minimal Published Event" and 4.1.2 "Changing a Published Event" I am sending what I believe is a spec-compliant published event, and subsequent update. Both Outlook 2010 and GMail see the update as a NEW EVENT. So at this point I'm going to assume Outlook and GMail have only partial support for *.ics files, give up on elegant updates and simply instruct the user to delete their old calendar appointment if I send them a new one.</p> |

33,447,417 | 0 | <p>A macro definition cannot include preprocessor directives (anything beginning with a <code>#</code>).</p> <p>To conditionally expand to certain values requires rather involved macrology and might not always work out the way you want. The example above could be written something like this:</p> <pre><code>#define ONE_OR_TWO(...) ONE_OR_TWO_(__VA_ARGS__, 2, 1,) #define ONE_OR_TWO_(_1, _2, X, ...) X #define CAT(A, B) CAT_(A, B) #define CAT_(A, B) A ## B #define M(N) CAT(IF_, ONE_OR_TWO(CAT(IS_, N)))({\ code; \ code; \ }, N) #define IS_5 , #define IF_1(A, B) B #define IF_2(A, B) A M(5); //-> { code; code; } M(8); //-> 8 </code></pre> <p>This is incredibly fragile though. You can only use certain types of expression as the argument to <code>M</code>, for instance - they have to have a syntactic structure that allows for concatenation, and no unwrapped commas - and it only works for predetermined values (e.g. to compare against something more complicated than a simple number is not possible with this method, because you can't build a macro name out of a more complex expression).</p> <p>But in principle, it can be done. You just need thousands upon thousands of lines of macro definitions to cover a useful set of cases beyond the trivial ones like this. You can get those by using a metaprogramming library like <a href="https://github.com/VesaKarvonen/order-pp">Order-PP</a> or <a href="http://www.boost.org/doc/libs/1_59_0/libs/preprocessor/doc/index.html">Boost.Preprocessor</a>, but be prepared for obscure error messages if you slip up in the syntax even slightly.</p> |

I've taken at lot of the code from the answer in <a href="http://stackoverflow.com/questions/27900344/how-to-make-a-table-column-with-integer-datatype-editable-without-changing-it-to">this</a> thread.

But there are two main issues with this:</p> <ol> <li><p>Once I've pressed enter and a cell has been edited. I can't edit it again by clicking on it. I need to press another row to be able to edit it again. Setting to focus on the parent of the row didn't do the trick.</p></li> <li><p>The code inside <code>commitEdit()</code> works. But it is ugly and using a <code>ObservableListWrapper</code> gives me the warning "Discouraged access: The type 'ObservableListWrapper' is not API (restriction on required library 'C:\Program Files\Java\jre1.8.0_60\lib\ext\jfxrt.jar')". Also the cell index is hard coded, which wont work if I use this in many different columns.</p></li> </ol> <p>None of the issues mentioned above is acceptable.</p> <p>The final implementation must support restriction of the input in the textfield. As far as I understand it this means that I need to have access to the <code>TextField</code> object displayed in the cell, as in my current implementation.</p> |

17,521,655 | 0 | <p>Your best choice is really to fake all "not interesting" schemas. </p> <p>Or you can add your own ErrorListener and carefully analyze the errors to determine the schema they relate to. But this might not be full proof since there can be "other schema"-related errors that stop the validation.</p> |

23,910,232 | 0 | <p>As I see it, you have a few options, depending on exactly what you want to achieve in your tests now, and what you might want to be able to do in the future.</p> <p>1) If your test does not need the websocket configuration at all, change it to point at a custom context configuration that does not include the <code>WebSocketConfig</code>.</p> <p>2) If your test needs the websocket config, but you don't need the broker relay (I can't see why it would be required in a test), you could add another Configuration for testing that uses <code>registry.enableSimpleBroker("/topic", "/queue/")</code> instead of <code>enableStompBrokerRelay</code>. Then there will be no TCP connection to the broker. The obvious disadvantage with this approach is that you are not testing your actual config, and that you are duplicating the destination prefixes.</p> <p>3) Run an embedded STOMP broker for your tests. I'm not 100% certain such a thing exists - I know ActiveMQ has STOMP support and some support for <a href="http://activemq.apache.org/vm-transport-reference.html" rel="nofollow">running inside a VM</a>, but I haven't tried this with STOMP. If possible, the advantage of this approach is that your tests would be testing something very close to the real code.</p> <p>4) You could customise the STOMP broker relay to such an extent that you have full control over what your application receives from the broker. You can customise the <a href="https://github.com/spring-projects/spring-framework/blob/master/spring-messaging/src/main/java/org/springframework/messaging/simp/stomp/StompBrokerRelayMessageHandler.java" rel="nofollow"><code>StompBrokerRelayMessageHandler</code></a> which manages the connection to the relay broker by adding a Configuration class that extends <a href="https://github.com/spring-projects/spring-framework/blob/master/spring-websocket/src/main/java/org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.java" rel="nofollow"><code>DelegatingWebSocketMessageBrokerConfiguration</code></a> in order to override the <code>stompBrokerRelayMessageHandler()</code> method. For example, you can set the TCP client it uses to your own implementation of <code>TcpOperations</code>. Below is an example TCP client that simply does nothing, i.e. makes the Handler think it is connected, but cannot receive or send messages.</p> <pre><code>@Override public AbstractBrokerMessageHandler stompBrokerRelayMessageHandler() { AbstractBrokerMessageHandler handler = super.stompBrokerRelayMessageHandler(); if (handler instanceof StompBrokerRelayMessageHandler) { StompBrokerRelayMessageHandler stompHandler = (StompBrokerRelayMessageHandler) handler; stompHandler.setTcpClient(new TcpOperations<byte[]>() { @Override public ListenableFuture<Void> connect(TcpConnectionHandler<byte[]> connectionHandler) { return new CompletedListenableFuture<>(null); } @Override public ListenableFuture<Void> connect(TcpConnectionHandler<byte[]> connectionHandler, ReconnectStrategy reconnectStrategy) { return new CompletedListenableFuture<>(null); } @Override public ListenableFuture<Void> shutdown() { return new CompletedListenableFuture<>(null); } }); } return handler; } </code></pre> <p>Note that <code>CompletedListenableFuture</code> is just an implementation of <code>ListenableFuture</code> that is done after construction, and immediately calls any callbacks passed to <code>addCallback</code> with the value passed into the constructor.</p> <p>The point here is that you can easily customise the exact behaviour of the broker relay components, so you can control them better in your tests. I am not aware of any built-in support to make this kind of testing easier, but then again the websocket support is still pretty new. I would suggest that you look at Rossen Stoyanchev's excellent example project <a href="https://github.com/rstoyanchev/spring-websocket-portfolio" rel="nofollow"><code>spring-websocket-portfolio</code></a>, if you haven't done so already, as it includes several examples of how to test the websocket configuration at different levels (just one controller, loading the full context, running an embedded server, ...). Hopefully this is also helpful for deciding how you want to test your application, and what you might need to customise to do it.</p> |
15,831,540 | 0 | UIView animations canceling each other <p>I have a problem when playing multiple UIView animation blocks.</p> <p>What I have is a game with a lot of buttons, when you press a button it spawns an UILabel which animates to the top of the screen where is gets "added" to the total point amount, this is done by using 3 nested blocks. This works well an lets me spawn as many point labels as possible with animations on them.</p> <pre><code> //setup the label UILabel *pointIndicator = [[UILabel alloc]initWithFrame:CGRectMake(button.button.frame.origin.x, button.button.frame.origin.y, 60, 30)]; pointIndicator.backgroundColor = [UIColor clearColor]; pointIndicator.font = [UIFont boldSystemFontOfSize:25]; pointIndicator.alpha = 0; pointIndicator.layer.shadowOffset = CGSizeMake(1.0f, 1.0f); pointIndicator.layer.shadowOpacity = 0.6; pointIndicator.layer.shadowRadius = 1; [pointIndicators addObject:pointIndicator]; [self.view addSubview:pointIndicator]; CGPoint scoreLabelPosition = [self.view convertPoint:self.totalScoreLabel.frame.origin fromView:self.totalScoreLabel.superview]; CGSize scoreLabelSize = [self.totalScoreLabel.text sizeWithFont:self.totalScoreLabel.font]; [UILabel animateWithDuration:0.3 delay:0 options:UIViewAnimationCurveEaseIn animations:^{ //Make label appear and move it above button CGRect frame = pointIndicator.frame; frame.origin.y -= 30; pointIndicator.frame = frame; pointIndicator.alpha = 1; }completion:^(BOOL finished){ [UILabel animateWithDuration:0.4 delay:0 options:UIViewAnimationCurveEaseInOut animations:^{ //Move the label next to the score label NSInteger YPosition = 0; if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){ YPosition = 15; }else{ YPosition = 2; } CGRect frame = pointIndicator.frame; frame.origin.x = scoreLabelPosition.x + self.totalScoreLabel.frame.size.width/2 + scoreLabelSize.width/2 + 5; frame.origin.y = scoreLabelPosition.y - self.totalScoreLabel.frame.size.height/2 + YPosition; pointIndicator.frame = frame; }completion:^(BOOL finished){ [UILabel animateWithDuration:0.5 animations:^{ pointIndicator.alpha = 0; }completion:^(BOOL finished){ //Animate point label to increase a bit in size CABasicAnimation *pointAnim = [CABasicAnimation animationWithKeyPath:@"transform"]; pointAnim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; pointAnim.duration = 0.1; pointAnim.repeatCount = 1; pointAnim.autoreverses = YES; pointAnim.removedOnCompletion = YES; pointAnim.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(1.5, 1.5, 1.0)]; [self.totalScoreLabel.layer addAnimation:pointAnim forKey:nil]; [pointIndicator removeFromSuperview]; [pointIndicators removeObject:pointIndicator]; }]; }]; }]; </code></pre> <p>However, when the game is ended all the buttons animate out of the screen and an image view grows in size out of the middle, each are using 1 animation block.</p> <p>The problem is that if an UILabel is animating across the screen at the same time as the game ends it cancels the button animation AND the growing image animation. If no UILabels are spawned everything plays as it should. I tried to cancel and remove all the point labels before playing the other animations, but with no luck. It only seems to work if all the previous animations have been completed normally in advance. This is how I remove them:</p> <pre><code>for(UIView *pointView in pointIndicators){ [pointView.layer removeAllAnimations]; [pointView removeFromSuperview]; } [pointIndicators removeAllObjects]; [self.totalScoreLabel.layer removeAllAnimations]; </code></pre> <p>all the views which are animated are subviews of the same UIView. I noticed that if I make the point labels subviews of the buttons all the animations can play at the same time.</p> <p>I cant seem to figure out this behavior, is there some sort of conflict between the animations?</p> |
17,106,749 | 0 | <p>Well, actually you can. I don't care about portability, but in VS you can do it. Assuming that we are building 32-bit code with VS, the first 4 bytes at the objects address is the vtable address.

25,662,950 | 0 | <p>If DateTimeType were an attribute, this could be done conveniently using conditional type assignment.

36,954,450 | 0 | <p>I built a similar system several years ago using MongoDB on Amazon AWS. This year, tired of doing DevOps on AWS (nod to @AndreiVolgin), I've moved it to Google BigQuery.</p> <p>Datastore for my use case was overkill and frankly, limiting. I would have wanted to turn off indexes for most attributes anyways to save on storage cost. Limiting because it's harder to hook up datastore-based data with a visualization tool such as Tableau.</p> <p>Regarding </p> <blockquote> <p>I know there's a solution called BigQuery by Google, which I believe does what I want and allows me to serve the data I want to customers with high flexibility and efficiency, but as I understood it works only on datastore "backups", I need to serve data in real time.</p> </blockquote> <p>When my system receives a datum, page visitor data in your example, it <a href="https://cloud.google.com/bigquery/streaming-data-into-bigquery" rel="nofollow">streams it directly to BQ</a>. So no, it doesn't only work on backups. Whether you can use it to report "real time" depends on what real time means to you. My system computes aggregate statistics once every couple hours for presentation to users.</p> |

2,578,832 | 0 | <p>MSBuild (which VS uses to do builds, from 2005/.NET2) supports parallel builds. By default VS will set the maximum degree of parallelism to your number of processors. Use Tools | Options | Projects and Solutions | Build and Run to override this default.</p> <p>Of course any one build might have more limited (or no) capacity to allow parallel builds. E.g. only one assembly in a solution provides no scope to build in parallel. Equally a large number of assemblies with lots of dependencies might block parallelism (A depends on B, C depends on A&B, D depends on C has no scope for parallel builds).</p> <p>(NB. for C++, in VS 2005 & 2008 uses its own build system, in 2010 C++ will also be built with MSBuild.)</p> |
