Hence the change in file size.</p> <p>It's possible to change the encoding used for the save as described by dbc above:</p> <blockquote> <p>Create an XmlWriterSettings, set XmlWriterSettings.Encoding as appropriate, then create an XmlWriter and pass it to XDocument.Save().</p> </blockquote> |

33,874,881 | 0 | <p>I don't know why you want to keep the unidirectional relation here, because making it bidirectional would make your life much easier.</p> <p>First, <code>CascadeType.ALL</code> on the parent mapping in your example means that if you delete the subfolder, its parent will be deleted also. And this will propagate all the way up to the root folder which is probably not what you want.</p> <p>With bidirectonal mapping it would look like this</p> <pre><code>@ManyToOne @JoinColumn(name = "parent_folder_id") protected Folder parentFolder; @OneToMany(mappedBy = "parentFolder", cascade = {CascadeType.ALL}) protected Set<Folder> children; </code></pre> <p>Without this, you should implement the cascade yourself. This will get complicated for more complicated folder structures (when checking the children of a folder before deletion, you'll have to check grandchildren... and so on). It could be done with one recursive method, but definitely a lot more work than with bidirectional relation.</p> <pre><code>/* pseudo code */ public void deleteFolder(Folder f) { Set<Folder> children = session.createQuery("from Folder where parentFolder.id = :parentId").setParameter("parentId", f.getId()).list(); for each child { deleteFolder(child) } session.delete(f) } </code></pre> |

The people running the upgrade project have assembled a list of applications that need to be installed on every machine, and myself and my colleagues are being tasked with testing all these apps in the new OS.</p> <p>We have three different versions of the Visual C++ Redistributable on our master list of applications, but nobody seems to know exactly which applications uses these libraries, and they want us to test them. Merely verifying that they're installed is not enough.</p> <p>I doubt there is any good way to see if an application references the visual c++ redist, but if there is let me know. I was wondering if there was any kind of visual c++ "test app" available that would let me execute some code from the libraries. Or maybe I would have to develop something, but I'm a C# guy so I'm not too familiar. If this proves to be too difficult or if I can come up with a good explanation of why we don't need to do this, then perhaps I can convince the project managers this isn't necessary.</p> <p>So... can anybody suggest a good way I could <em>test</em> the Visual C++ Redistributable?</p> |

29,263,645 | 0 | MS Access shared on SharePoint with multiple users and linked tables <p>I have an Access Database (2010) that uses a linked table from a SharePoint (2013) list of names. It does not edit the information on the SharePoint list, but rather pulls the names from SP to populate the name field in the new records in Access. The user then can add in the additional information stored in the Access DB (in this case, it is somewhat of a "report card" form that allows the teacher to input student's grades).</p> <p>This DB is stored on a SharePoint site. When teachers try to use it, they are prompted to save the DB locally and then "Save to SharePoint" when they are done. The problem is that if two teachers are using it at the same time and one saves to SP after the other, the latter teacher will overwrite all the changes that the former teacher made.</p> <p>I've done some research and it seems that "splitting" the Access DB might work to allow teachers to simultaneously edit (only a maximum of 6 users will be editing at the same time). But I have not tried this method before. Will splitting into front-end and back-end affect the linked table of names that is taken from a SharePoint list? What is the best way to allow simultaneous edits?</p> |

32,924,740 | 0 | Found this strange behaviour of Handlers in android <p>I just wrote a code which adds several views, each using a handler. These are added using a for-loop. These add just correctly. Then I tried to add a button AFTER the for loop without using handler. This time the button was shown on the top of the layout i.e BEFORE the items added in for loop. This does not happen if I add the button using handler.</p> <p>So, if I use the following code with a handler after the loop then the button is added on the bottom of the layout:</p> <pre><code> private void fillFeedWithData(final List<ParseObject> feedObjectList) { LayoutInflater inflaterOfFeedItem = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); for (int i = 0; i < feedObjectList.size(); i++) { final String jokeTitle = feedObjectList.get(i).getString("content"); final View cvFeedItem = inflaterOfFeedItem.inflate(R.layout.feed_item_theme_card, null); final TextView tvJoke = (TextView) cvFeedItem.findViewById(R.id.tvFeedJoke); Handler h2 = new Handler(); Runnable update2 = new Runnable() { public void run() { tvJoke.setText(jokeTitle); llFragmentFeedParent.addView(cvFeedItem); // llFragmentFeedParent is acquired in OnCreate() method } }; h2.post(update2); } final Button bNext = new Button(this); bNext.setText("Next >"); bNext.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); Handler h3 = new Handler(); Runnable update3 = new Runnable() { public void run() { llFragmentFeedParent.addView(bNext); } }; h3.post(update3); } </code></pre> <p>If I used the following code after the loop then the button is added on the top of the layout:</p> <pre><code> Button bNext = new Button(this); bNext.setText("Next >"); bNext.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); llFragmentFeedParent.addView(bNext); </code></pre> <p>So now my app is working as intended with the handler but I am concerned as to why this was happening. I think the handlers are mixing up the timings/sequence of execution? If I keep using the logic, is it possible that the button might, in a slow mobile phone, appear on top or even in between the items added in the loop?</p> |

11,805,251 | 0 | Add HTML elements dynamically with JavaScript inside DIV with specific ID <p>Ok, poeple, I need your help. I've found some code here on Stackoverflow (can't find that link) which generate HTML code dynamically via JS. Here is code:</p> <pre><code>function create(htmlStr) { var frag = document.createDocumentFragment(), temp = document.createElement('div'); temp.innerHTML = htmlStr; while (temp.firstChild) { frag.appendChild(temp.firstChild); } return frag; } var fragment = create('<div class="someclass"><a href="www.example.com"><p>some text</p></a></div>'); document.body.insertBefore(fragment, document.body.childNodes[0]); </code></pre> <p>This code work's just fine! But generated code apears on top of page, right below <code>body</code> tag. My wish is to generate that code inside empty <code>div</code> with specific <code>id="generate-here"</code>.</p> <p>So output will be:</p> <pre><code><div id="generate-here"> <!-- Here is generated content --> </div> </code></pre> <p>I know that I can't see generated content with "view source". I only need to generate that content just in this particular place with <code>#generate-here</code>. I'm Javascript noob, so if anyone can just rearrange this code that will be perfect. Thanks a lot!</p> <p>P.S. I know how to do this with Jquery, but I need native and pure JavaScript in this case.</p> |
37,041,146 | 0 | <p>You need to use a (derived) table of values. Here is a solution using <code>left join</code> instead of <code>not in</code>:</p> <pre><code>select n.n from (select 1 as n union all select 2 union all select 4 union all select 5 union all select 6 union all select 7 ) n left join tablename t on t.id = n.n where t.id is null; </code></pre> |
21,799,138 | 0 | Django/HTML - what "value", "id" and "name" fields stand for? <p>I've gone through all the official Django tutorial, but I can't seem to figure out a template section of it. I have the following form</p> <pre><code><form action="{% url 'polls:vote' poll.id %}" method="post"> {% csrf_token %} {% for choice in poll.choice_set.all %} <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}" /> <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br /> {% endfor %} <input type="submit" value="Vote" /> </form> </code></pre> <p>I understand that this code accepts an input, and returns request.POST dictionary to the polls:vote view. However, in the 4th line of code, I don't understand what's the roll of name, id and value in this whole operation?</p> <p>Could anyone give me a clue on this?</p> |

It's just a start for an idea but hopefully this is enough information to spark something.</p> |
