39,646,916 | 0 | How to run exe file in VM using PowerCLI? <p>Recently I am working on VMs, using vSphere. I'm also using PowerCLI to automate some stuff. I discovered the cmdlet <code>Invoke-VMScript</code> which allows scripts to be ran on the VM using PowerShell.</p> <p>Everything worked just fine until I tried to install a program in the VM:</p> <pre><code>Invoke-VMScript -VM $vm -ScriptText " 'path'.exe" -GuestUser "YourUsername" -GuestPassword "YourPassword" </code></pre> <p>The program won't run, but we can see the process runs. I explored more and discovered it happens in every exe file. It just won't display the GUI, and also won't perform the desired operation.</p> <p>What can I do to make the PowerCLI run EXE files?</p> |

This checkbox needs to be UNCHECKED, because this will clear your SharedObject on each application launch!</p> <p>To access this configuration screen in Flash Builder 4.5, click the tiny arrow next to your run/debug button and click Run/Debug Configurations.

33,194,823 | 0 | <p>That's right. <code>PriorityQueue</code> of Java does not offer a method to update priority and it seems that deletion is taking linear time since it does not store objects as keys, as <code>Map</code> does. It in fact accepts same object multiple times.</p> <p>I also wanted to make PQ offering update operation. Here is the sample code using generics. Any class that is Comparable can be used with it.</p> <pre><code>class PriorityQueue<E extends Comparable<E>> { List<E> heap = new ArrayList<E>(); Map<E, Integer> map = new HashMap<E, Integer>(); void insert(E e) { heap.add(e); map.put(e, heap.size() - 1); bubbleUp(heap.size() - 1); } E deleteMax() { if(heap.size() == 0) return null; E result = heap.remove(0); map.remove(result); heapify(0); return result; } E getMin() { if(heap.size() == 0) return null; return heap.get(0); } void update(E oldObject, E newObject) { int index = map.get(oldObject); heap.set(index, newObject); bubbleUp(index); } private void bubbleUp(int cur) { while(cur > 0 && heap.get(parent(cur)).compareTo(heap.get(cur)) < 0) { swap(cur, parent(cur)); cur = parent(cur); } } private void swap(int i, int j) { map.put(heap.get(i), map.get(heap.get(j))); map.put(heap.get(j), map.get(heap.get(i))); E temp = heap.get(i); heap.set(i, heap.get(j)); heap.set(j, temp); } private void heapify(int index) { if(left(index) >= heap.size()) return; int bigIndex = index; if(heap.get(bigIndex).compareTo(heap.get(left(index))) < 0) bigIndex = left(index); if(right(index) < heap.size() && heap.get(bigIndex).compareTo(heap.get(right(index))) < 0) bigIndex = right(index); if(bigIndex != index) { swap(bigIndex, index); heapify(bigIndex); } } private int parent(int i) { return (i - 1) / 2; } private int left(int i) { return 2*i + 1; } private int right(int i) { return 2*i + 2; } } </code></pre> <p>Here while updating, I am only increasing the priority (for my implementation) and it is using MaxHeap, so I am doing bubbleUp.

20,984,959 | 0 | <p>The pointer returned by placement new can be just as UB-causing as any other pointer when aliasing considerations are brought into it. It's your responsibility to ensure that the memory you placed the object into isn't aliased by anything it shouldn't be.</p> <p>In this case, you cannot assume that <code>uint8_t</code> is an alias for <code>char</code> and therefore has the special aliasing rules applied. In addition, it would be fairly pointless to use an array of <code>uint8_t</code> rather than <code>char</code> because <code>sizeof()</code> is in terms of <code>char</code>, not <code>uint8_t</code>. You'd have to compute the size yourself.</p> <p>In addition, <code>reinterpret_cast</code>'s effect is entirely implementation-defined, so the code certainly does not have a well-defined meaning.</p> <p>To implement low-level unpleasant memory hacks, the original memory needs to be only aliased by <code>char*</code>, <code>void*</code>, and <code>T*</code>, where <code>T</code> is the final destination type- in this case <code>int</code>, plus whatever else you can get from a <code>T*</code>, such as if <code>T</code> is a derived class and you convert that derived class pointer to a pointer to base. Anything else violates strict aliasing and hello nasal demons.</p> |

33,249,484 | 0 | <p>Some close alternatives are <code>std::vector</code> and <code>std::array</code>. </p> <p>If you want to use an array of bytes, usually <code>uint8_t</code>, you will need to pass the array to functions, <em>as well as the capacity and the number of elements in the array</em>. </p> <p>The issue is that when arrays are passed to functions, the array decays down to a pointer to the first element, without any capacity information. </p> <p>There are no facilities to prevent you from indexing beyond the limits (capacity) of the array.

I will only be focusing on how to implement DataTables with row details in MVC. </p> <hr> <p>My models:</p> <pre><code>public class Advisor { public int Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Discipline { get; set; } } public class Student { public int Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Major { get; set; } public int AdvisorId { get; set; } } </code></pre> <p>Given my models, I have a view that displays a table of advisors:</p> <pre><code>@model IEnumerable<DataTablesMvcExample.Models.Advisor> @{ ViewBag.Title = "Index"; //eg, [url]/Advisor Layout = "~/Views/Shared/_Layout.cshtml"; //will explain later } <table id="sort"> <thead> <tr> <th>First Name</th> <th>Last Name</th> <th>Discipline</th> </tr> </thead> <tbody> @foreach (var item in Model) { <tr> <td>@item.FirstName</td> <td>@item.LastName</td> <td>@item.Discipline</td> </tr> } </tbody> </table> </code></pre> <p>I would like to display the students each advisor advises. To do this:</p> <p>1) In my controller, with respect to the view in which the table above lies, I add the code below:</p> <pre><code>public ActionResult AdvisorStudents(int advisorId) { var advisorStudents = //retrieve students based on their advisor return View(advisorStudents); } </code></pre> <p>2) I create a view called AdvisorStudents.cshtml (eg, [url]/Advisor/AdvisorStudents)</p> <pre><code>@model IEnumerable<DataTablesMvcExample.Models.Student> @{ Layout = null; //Using a layout will cause this table to not open as row details. I was at a loss until I explicitly defined this. } <table> <thead> <tr> <th>First Name</th> <th>Last Name</th> <th>Major</th> </tr> </thead> <tbody> @foreach (var item in Model) { <tr> <td>@item.FirstName</td> <td>@item.LastName</td> <td>@item.Major</td> </tr> } </tbody> </table> </code></pre> <p>3) In the view the table of advisors lie, I add the JavaScript below, DISCLAIMER: I borrowed a lot of this from the aforementioned reference.</p> <pre><code><script type="text/javascript"> var oTable; $(document).ready(function () { $('#sort tbody td img').click(function () { var nTr = this.parentNode.parentNode; /* close image is displayed while viewing row details*/ if (this.src.match('close')) { //ie, match "~/[directory]/*close*.png" /* close this row as it is open */ this.src = //path of open image oTable.fnClose(nTr); } /* open image is displayed to view row details */ else { /* open this row */ this.src = //path of close image var advisorId = $(this).attr("rel"); $.get("Advisor/AdvisorStudents?AdvisorId=" + advisorId, function (students) { oTable.fnOpen(nTr, students, 'row_details'); }); } }); /* Initialize datatable and make column that opens/closes non-sortable*/ oTable = $('#sort').dataTable({ "bJQueryUI": true, "aoColumns": [ { "bSortable": false, "bSearchable": false }, null, null, null ] }); }); </script> </code></pre> <p>When I initialize the DataTables for the table of advisors above, I specify four columns, with the first column not sortable or searchable. The table of advisors specified three columns above. The column not specified, which will become my first column, is where my open/close display will go. I add a header cell <code><th></th></code> and a standard cell <code><td><img src=//path of open image alt="expand/collapse" rel="@item.Id"/></td></code> as the first column to achieve this.</p> <p>NOTE: You can have the open/close display in any column you'd like. To do so:</p> <p><strong>Javascript</strong></p> <ul> <li>Change <code>td</code> in <code>$('#sort tbody td img')</code> to <code>td:nth-child(x)</code> or <code>td:last-child</code>.</li> <li>Have the not sortable/searchable declaration match which column you wish to have your open/close display on</li> </ul> <p><strong>HTML</strong></p> <ul> <li>Have the <code><th></code> and <code><td></code> cells match which column you wish to have your open/close display on</li> </ul> <p><img src="https://i.stack.imgur.com/oOo21.png" alt="DataTables with row details in MVC 4"></p> <p>Hope this helps someone. <strike>I have a <a href="http://sscce.org/" rel="nofollow noreferrer">SSCCE</a> by request.</strike> I know this is a necrobump, but I couldn't find a suitable example (aside from the one I reference above) to suit my needs.

26,726,595 | 0 | <p>The part you are asking about is an anonymous method that uses a lambda expression. It is commonly used in callbacks.</p> <p>When you write this</p> <pre><code>(machine, error) => { SelectedMachine = new MachineViewModel(machine); } </code></pre> <p>you are making a function that has no name (and therefore cannot be reused by name, like a regular method). It is very convenient in situations when you need to produce a piece of callable code that needs to be used only once, e.g. in callbacks.</p> <p>Note that the method does not have to be anonymous: you could make an equivalent named method. However, an since the anonymous method is built in the context of the method where it is used, the variables from the context are available to it. Your anonymous method assigns <code>SelectedMachine</code>, which is probably a property of your class. In the same way, anonymous methods can access local variables as well, which is a very powerful mechanism of combining together a state and a piece of code that operates on it.</p> |

11,136,477 | 0 | <p>The easiest way is to try to red it, and catch the exception.</p> <p>Catching the exception is done by defining an entry in the <code>__ex_table</code> secion, using inline assembly.<br> The exception table entry contains a pointer to a memory access instruction, and a pointer to a recovery address.

30,066,110 | 0 | <p>"Hash table" is just a fancier way of saying "ordinary Javascript object". What the instructor means by "handle to its definition" is just another way of saying "the function that acts as a constructor for the class".</p> <p>Ultimately, what he means by the statement you mentioned:</p> <blockquote> <p>each overloaded entity definition will update a hash table with a pointer to its class definition</p> </blockquote> <p>is the following:</p> <ul> <li>All "subclasses" of Entity will register their constructor function in a single shared hashmap/object using the key which is the <code>type</code> value.</li> <li>This allows you to get the constructor function (in other words, the function to call <code>new</code> on, which will return an instance of that entity) for any type by accessing <code>gGameEngine.factory[type]</code>.</li> </ul> <p>This is nice, because whenever a programmer adds a new type of entity, so long as they remember to add a new entry to that <code>gGameEngine.factory</code> object with the correct key, then that object will contain everything you need to construct any type of supported object.</p> <p>So the code that iterates over the JSON structure generated by the level editor can create an instance of any type the same way, using something like:</p> <pre><code>var typeConstructor = gGameEngine.factory(tileSpec.type), instance; if (typeConstructor) { instance = new(typeConstructor)(tileSpec /* or whatever params */); } </code></pre> <p>This is similar to the code visible at around the 1 minute mark of the video you linked to.</p> <p>Make sense now?</p> |

16,182,526 | 0 | Android multiline edittext not increasing its height as the user types <p>So the layout is quite simple. A <code>ListView</code> occupying most of the screen, and a <code>RelativeLayout</code> at the bottom containing the <code>EditText</code> and a <code>Button</code> to the right. Everything looks great, but the problem is that as the user types and enters new lines, the <code>EditText</code> is not increasing its height just enough so that the user can see all the text types without scrolling.

14,777,514 | 0 | <p>I've been wondering this for a while also; the OpenCV documentation isn't very helpful when it comes to blob detection.</p> <p>Based on the descriptions of <a href="http://www1.adept.com/main/KE/Data/ACE/AdeptSight_User/BlobAnalyzer_Results.html#Intrinsic_Inertia_Results">other blob analyzers</a>, the inertia of a blob is "the inertial resistance of the blob to rotation about its principal axes". It depends on how the mass of the blob (I guess in this case the area) is distributed throughout the blob's shape.</p> <p>There's a lot of mathy stuff involved -- most of which I don't remember how to do -- but the result at the bottom of <a href="http://homepages.inf.ed.ac.uk/rbf/CVonline/LOCAL_COPIES/OWENS/LECT2/node3.html">this page on the properties of binary images</a> sums it up fairly well (blob detection is done by converting the input image to a series of binary images):</p> <blockquote> <p>The ratio <img src="https://chart.googleapis.com/chart?cht=tx&chl=I_%7Bmin%7D%2FI_%7Bmax%7D&chf=bg,s,65432100" alt="I_min/I_max"> gives us some idea of how rounded the object is. This ratio will be 0 for a line and 1 for a circle.</p> </blockquote> <p>So basically, by specifying <code>minInertiaRatio</code> and <code>maxInertiaRatio</code> you can filter the blobs based on how elongated they are. An inertia ratio of 0 will yield elongated blobs (closer to lines) and an inertia ratio of 1 will yield blobs where the area is more concentrated toward the center (closer to circles).</p> |

You basically have to write wrappers to do server requests to get a polyline between two locations and then you add it to the map. </p> <p>Also, <a href="https://developers.google.com/maps/documentation/ios/">look here</a> for the full documentation and basic code snippets.</p> <p>Good luck!</p> |

38,004,875 | 0 | iOS app submission and beta review process <p>I'm currently developing an iOS application for a client. The submission review process to the store can often be a lengthy process and is relatively new to me. </p> <p>My client wants to do a beta test using <strong>TestFlight</strong> as well as submitting the app to the app store afterwards, through <strong>XCode</strong> and <strong>Itunes Connect</strong>.</p> <p>Scouring Apple's documentation I can't seem to get a good idea of following:</p> <ul> <li><p><strong>If I want to update an existing application on the store do I have to go through the review process again in full?</strong><br><br></p></li> <li><p><strong>If I have my app approved for beta testing release through TestFlight, is this taken into consideration when submitting the app for review to the store?</strong><br><br></p></li> <li><p><strong>If I want to test a new build through TestFlight, do I need to go through the beta review process again in full?</strong><br><br></p></li> <li><p><strong>If an app is approved on the app store, does it automatically pass the beta review?</strong><br> (This sounds counterintuitive considering you don't want to do a beta test after releasing to the store but in a scenario where you may want to do a closed release of an update for testing while a live version is up on the store)</p></li> </ul> |
