Can it handle more complex views than ListView ?</p> <p>I've been using ListView till now and for a few, is it time to switch to RecyclerView or is it too soon now?</p> |

35,155,904 | 0 | <p>The simplest and pretty much idiomatic way to do it would be:</p> <pre><code>QMap<QString, QVector<QString>> devices; // Get the vector constructed in the map itself. auto & commands = devices[RadioID]; // Fill commands with lots of data here - a bit faster commands.resize(2); commands[0] = "Foo"; commands[1] = "Bar"; // Fill commands with lots of data here - a bit slower commands.append("Baz"); commands.append("Fan"); </code></pre> <p>You'll see this pattern often in Qt and other code, and it's the simplest way to do it that works equally well on C++98 and C++11 :)</p> <p>This way you're working on the vector that's already in the map. The vector itself is never copied. The members of the vector are copied, but they are implicitly shared, so copying is literally a pointer copy and an atomic reference count increment.</p> |
18,713,652 | 0 | <p>The first thing to understand is why it keeps playing forever rather than just 0.2. You can see what's going on if you run the <code>Pbind</code> equivalent:</p> <pre><code> p = Pbind(\instrument, \default, \dur, 0.2, \freq, 400).play; </code></pre> <p>If you run this you don't just hear a single note, you hear the note being hit again and again forever, until you run</p> <pre><code> p.stop; </code></pre> <p>So why is that? It's because all of the "values" specified are simple numbers or symbols (<code>\default ... 0.2 ... 400</code>), and these are always interpreted as meaning "continue forever or until something else stops us".</p> <p>If you wanted Pbind to play just one note you would need to use at least one pattern in there which limits itself to just one item:</p> <pre><code> p = Pbind(\instrument, \default, \dur, 0.2, \freq, Pseq([400], 1)).play; </code></pre> <p>So you can do the same thing with Pmono:</p> <pre><code> p = Pmono(\default, \dur, 0.2, \freq, Pseq([400], 1)).play; </code></pre> <p>This has <em>exactly the same result</em> as the Pbind example, actually, but that's because it's playing only one note. We can make the difference a little bit clearer with these two-note examples:</p> <pre><code> p = Pbind(\instrument, \default, \dur, 0.4, \freq, Pseq([400, 500], 1)).play; p = Pmono(\default, \dur, 0.4, \freq, Pseq([400, 500], 1)).play; </code></pre> <p>The first plays two separate notes, the second plays one with a pitch change halfway through.</p> <p>So, note that your inference was correct - the node does get deleted after the Pmono terminates - but your Pmono was not terminating.</p> |
738,931 | 0 | <p>In case anyone ends up running into a similar situation, here was my solution: </p> <p>First to explain my datasets:</p> <pre><code>public Foo { string a; List<Bar> subInfo; } public Bar { string b; string c; } List<Foo> allFoos; </code></pre> <p>Basically instead of having the allFoos object that I passed to a master report, and then trying to pass the corresponding Bar object to the subReport, I created a new object:</p> <pre><code>Public FooBar { string a; string b; string c; } List<FooBar> allFooBars; </code></pre> <p>So basically I flattened the data. From there I created a single report. I added one table that had "FooBar" as it's DataSet, and passed in the collection of "allFooBars." I also created a footer on the report, so that I would have consistent paging across all pages. I then used grouping to keep "Foo" objects together. On the groups I set the "Page Break at start" and "Include Group Header" and "Repeat Group Header" options to true. Then I just set up the Group Headers to fake being my Page Headers along with group headers (basically just 5 lines of Group Headers, one of which was blank to provide some space).</p> <p>And that was basically it.</p> |

9,281,971 | 0 | <p>The issue is in the fact that by default images are vertically aligned with the baseline. You can see this if you put an image next to some text. The image aligns to the baseline of the text, while letters like g and y go below the baseline. The space you are getting is the space below the baseline which is for the letters to go below.

19,472,117 | 0 | <p>Basically, the idea is as follows:</p> <ol> <li><p>One of your pages checks whether the user knows the "secret". This is kind of authorization.</p></li> <li><p>Some other page(s) works only if the user has been authorized.</p></li> </ol> <p>It's obvious that information about successful authorization should be stored in some place, which is shared between various pages. There are a lot of ways to share information between pages.</p> <p>A) Session. Once the user has submitted the correct promo code, your authorizing page stores something in the Session collection. That could be just a flag indicating the fact of successful authorization, or that could be the promo code - if you would need its value later.</p> <p>Any other page can check what's stored (or not stored) in Session in the Page_Load handler and decide what to do then: continue or render an error, or redirect to another page. Note: sessions expire. What's you store there is forgotten when the session ends.</p> <p>B) Cookies. This way your information lasts as much time as you want - you set the expiry date. But since it's stored in the user's browser, there are disadvantages: the browser may refuse to store your cookies; the user may clear them.</p> <p>C) Database. If you want to make sure the user is authorized once and for ever, store this info in the database.</p> |

Using them will break your layout and cause other glitches.</p> <p>You have two options: Either replace the <code><nav></code> and any other HTML5 elements with old-style <code><div></code> elements, or use a polyfill like <a href="http://code.google.com/p/html5shiv/" rel="nofollow">html5shiv</a> or <a href="http://modernizr.com/" rel="nofollow">Modernizr</a>, both of which will fix the problem in IE8 and make these elements work as normal.</p> <p>Hope that helps.</p> <p><strong>[EDIT after OP clarified his IE version as IE10]</strong></p> <p>The other possibility is that it's displaying the page in compatibility mode or quirks mode.</p> <p>You can check the browser mode by pressing F12 to bring up the Dev Tools window; the mode information will be shown at the top of the window. If it's in either Quirks mode or compatibility mode (ie if it's in anything other than IE10 Standards mode) then there's a strong probability that this is the cause.</p> <p>If it's in quirks mode, it's because your HTML isn't standards compliant. Most of the time, adding a valid doctype to the top of the page will fix this (you can use <code><!DOCTYPE html></code> as the easiest valid doctype). You should also check for other errors in your HTML by running it through the <a href="http://validator.w3.org" rel="nofollow">W3C Validator</a> and fixing the errors it reports. (if the code you've posted is your whole code, then you're missing the <code><html></code> and <code><body></code> tags for starters, which is definitely not good).</p> <p>If it's in compatibility mode (eg "IE7 Standards"), then you can fix this by adding an <code>X-UA-Compatible</code> meta tag to your <code><head></code> section.

29,493,074 | 0 | <p>Here's the simplest solution:</p> <p>Assuming that you installed some up-to-date version of Perl and it is already in PATH, simply go to where GIT executables are is, which is normally </p> <pre><code>C:\Program Files (x86)\Git\bin </code></pre> <p>and <strong>rename <code>perl.exe</code> to <code>perl1.exe</code></strong>. If you really are so unhappy about this, rename it back after you're done with whatever is getting the problem.</p> <p>Why does this solve the problem? Because your program will not find perl in GIT's directory, and will try to find it somewhere else, and since your have the latest version of Perl in PATH, it will find it and everything will workout.</p> <p>PS: It worked with me :-)</p> |

I would like to avoid this if at all possible because it will mean spending a couple hours rewriting some code and messing with tests. </p> <p>The project is a forum site, and there are three main Schemas that comprise it (in addition to cursory Schemas for the forums, notifications, settings and the schemas for the user and the users activities). The Board Schema (contains a list of all forum sections if that wasn't apparent) Is a Schema that makes a reference to the Threads Schema so it can get the threads for each Board. My problem is in the Thread Schema.</p> <pre><code>var ThreadSchema = new mongoose.Schema({ ... other unrelated Schema stuff... comments: [{ created: { type: Date, default: Date.now }, creator: { type: mongoose.Schema.ObjectId, required: true, ref: 'User' }, content: { type: String, required: true, get: escapeProperty }, likes: [{ type: mongoose.Schema.ObjectId, required: false, ref: 'User' }], liked: { type: Boolean, default: false }, saved: [{ type: mongoose.Schema.ObjectId, required: false, ref: 'User' }] }] }); </code></pre> <p>blah blah blah.</p> <p>I'm trying to pull for the users profile only the comments that that user has posted. The threads were easy, but comment data is not coming through. The request to the server goes through as successful, but I don't get any data back. This is what I am trying.</p> <pre><code>obj.profileComments = function (req, res) { var userId = req.params.userId; var criteria = {'comments.creator': userId}; Thread.find(criteria) .populate('comments') .populate('comments.creator') .skip(parseInt(req.query.page) * System.config.settings.perPage) .limit(System.config.settings.perPage + 1) .exec(function (err, threads) { if (err) { return json.bad(err, res); } json.good({ records: threads }, res); }); }; </code></pre> <p>This is a controller, and the json.bad and json.good are helpers that I have created and exported they basically are res.send.</p> <pre><code>var good = function (obj, res) { res.send({ success: 1, res: obj }); }; </code></pre> <p>and the bad is very similar, it just handles errors in an obj.res.errors and puts them into messages.</p> <p>So now that that is all out of the way, I'm a little lost on what to do? Is this something I should try to handle with a method in my Schema? It seems like I might have a little bit more luck that way. Thank you for any help.</p> |

Here is the link for log:</p> <pre><code><%= link_to 'Log', new_part_out_log_path(@part, :format => :js), :remote => true, :id => 'new_log_link' %> </code></pre> <p>And the new.js.erb as this:</p> <pre><code>$("<%= escape_javascript render(:file => 'out_logs/new.html.erb') %>").insertAfter('#new_log_link'); $('#new_log_link').hide(); $('#close').hide(); </code></pre> <p>the problem is that after clicking 'Log', instead of one view, 2 identical views of out_logs/new.html.erb were rendered.

3,506,762 | 0 | <p>Look at how Spring does it, they have already figured out all this stuff and there is no need to re-invent it. Check out the petclinic sample code that is bundled with the full distribution of Spring, or (for a non-Spring approach) read the DAO chapter of the Bauer/King Hibernate book. </p> <p>Definitely the DAO shouldn't be in charge of getting the database connection, because you will want to group multiple DAO calls in the same transaction. The way Spring does it is there's a service layer that gets its transactional methods wrapped in an interceptor that pulls the connection from the datasource and puts it in a threadlocal variable where the DAOs can find it.</p> <p>Eating your SQLException and returning null is bad. As duffymo points out, letting the PreparedStatement get passed around with no assurance that it will ever get closed is very bad. Also, nobody should use raw JDBC anymore, Ibatis or spring-jdbc are better alternatives.</p> |
