  • PHP: Combine Two 16-bit Integers into a 32-bit integer

    - by Goro
    Hello, I am trying to combine two integers in my application. By combine I mean stick one byte stream at the end of the other, not concatenate the strings. The two integers are passed from hardware that can't pass a 32 bit value directly, but passes two consecutive 16-bit values separately. Thanks,

  • How to handle unknown initializer functions in lua?

    - by oofoe
    I want to load data written in a variant of lua (eyeonScript). However, the data is peppered with references to initialization functions that are not in plain lua: Redden = BrightnessContrast { Inputs = { Red = Input { Value = 0, }, }, } Standard lua gives "attempt to call a nil value" or "unexpected symbol" errors. Is there any way to catch these and pass it to some sort of generic initializer? I want to wind up with a nested table data structure. Thanks!

  • When are child views added to Layout/ViewGroup from XML

    - by JohnTube
    My question is : I want to know when does a xLayout (or ViewGroup in general) add a child view from XML ? And by "when" I mean at what point of code, in what "pass" of the "traversal" of the UI toolkit ? Which method of xLayout or ViewGroup should I override ? I have done my homework : I have watched the "Writing Custom Views For Android" presented (by Adam Powell and Romain Guy) in the last Google I/O and I have read Adam Powell comments on this Google+ post.

  • MVC-like Autogenerated Pages for Webforms

    - by CccTrash
    I noticed that MVC lets you pass in LINQ to SQL objects to its views and it will autogenerate Create, Update and View Pages based on the LINQtoSQL object. Is there anything for webforms that lets you do this kind of thing? (In a nice way with validators maybe?)

  • MVC validation error with strongly typed view

    - by Remnant
    I have a simple form that I would like to validate on form submission. Note I have stripped out the html for ease of viewing <%=Html.TextBox("LastName", "")%> //Lastname entry <%=Html.ValidationMessage("LastName")%> <%=Html.TextBox("FirstName", "")%>//Firstname entry <%=Html.ValidationMessage("FirstName")%> <%=Html.DropDownList("JobRole", Model.JobRoleList)%> //Dropdownlist of job roles <% foreach (var record in Model.Courses) // Checkboxes of different courses for user to select { %> <li><label><input type="checkbox" name="Courses" value="<%=record.CourseName%>" /><%= record.CourseName%></label></li> <% } %> On submission of this form I would like to check that both FirstName and LastName are populated (i.e. non-zero length). In my controller I have: public ActionResult Submit(string FirstName, string LastName) { if (FirstName.Trim().Length == 0) ModelState.AddModelError("FirstName", "You must enter a first name"); if (LastName.Trim().Length == 0) ModelState.AddModelError("LastName", "You must enter a first name"); if (ModelState.IsValid) { //Update database + redirect to action } return View(); //If ModelState not valid, return to View and show error messages } Unfortunately, this code logic produces an error that states that no objects are found for JobRole and Courses. If I remove the dropdownlist and checkboxes then all works fine. The issue appears to be that when I return the View the view is expecting objects for the dropwdownlist and checkboxes (which is sensible as that is what is in my View code) How can I overcome this problem? Things I have considered: In my controller I could create a JobRoleList object and Course object to pass to the View so that it has the objects to render. The issue with this is that it will overwrite any dropdownlist / checkbox selections that the user has already made. In the parameters of my controller method Submit I could aslo capture the JobRoleList object and Course object to pass back to the View. Again, not sure this would capture any items the user has already selected. I have done much googling and reading but I cannot find a good answer. When I look at examples in books or online (e.g. Nerddinner) all the validation examples involve simple forms with TextBox inputs and don't seems to show instances with multiple checkboxes and dropdownlists. Have I missed something obvious here? What would be best practice in this situation? Thanks

  • Rails - How do you test ActionMailer sent a specific email in tests

    - by adam
    Currently in my tests I do something like this to test if an email is queued to be sent assert_difference('ActionMailer::Base.deliveries.size', 1) do get :create_from_spreedly, {:user_id => @logged_in_user.id} end but if i a controller action can send two different emails i.e. one to the user if sign up goes fine or a notification to admin if something went wrong - how can i test which one actually got sent. The code above would pass regardless.

  • ASP.NET MVC Return to Previous Page

    - by Jason Enochs
    I have a basic Edit method in my controller that redirects back to a top level listing (“Index”) when the edit succeeds. Standard setup after scaffolding. I am trying to change this Edit method to redirect back to the previous page (not Index). Since my Edit method is not using the default mapped input parameter “id”, I am using that to pass the previous URL. In my Edit “get” method, I use this line to grab the previous URL and it works fine: ViewBag.ReturnUrl = Request.UrlReferrer.AbsoluteUri; I send this return URL to the Edit “post” method by using my form tag like this: @using (Html.BeginForm(new { id = ViewBag.ReturnUrl })) Now this is where the wheels fall off. I can't seem to get the URL parsed from the id parameter properly. UPDATE**** Using Gary's example as a guide, I changing my parameter name from "id" to "returnUrl" and used a hidden field to pass my parameter. Lesson: Only use the id parameter how it was intended to be used...keep it simple. It works now... Here is my updated code. // // GET: /Question/Edit/5 public ActionResult Edit(int id) { Question question = db.Questions.Find(id); ViewBag.DomainId = new SelectList(db.Domains, "DomainId", "Name", question.DomainId); ViewBag.Answers = db.Questions .AsEnumerable() .Select(d => new SelectListItem { Text = d.Text, Value = d.QuestionId.ToString(), Selected = question.QuestionId == d.QuestionId }); ViewBag.returnUrl = Request.UrlReferrer; ViewBag.ExamId = db.Domains.Find(question.DomainId).ExamId; ViewBag.IndexByQuestion = string.Format("IndexByQuestion/{0}", question.QuestionId); return View(question); } // // POST: /Question/Edit/5 [HttpPost] public ActionResult Edit(Question question, string returnUrl) { int ExamId = db.Domains.Find(question.DomainId).ExamId; if (ModelState.IsValid) { db.Entry(question).State = EntityState.Modified; db.SaveChanges(); //return RedirectToAction("Index"); return Redirect(returnUrl); } ViewBag.DomainId = new SelectList(db.Domains, "DomainId", "Name", question.DomainId); return View(question); } and I changed my form tag to this: @using (Html.BeginForm()) { <input type="hidden" name="returnUrl" value="@ViewBag.returnUrl" /> Thanks Gary

  • Understanding Haskell's filter

    - by dmindreader
    I understand that Haskell's filter is a high order function (meaning a function that takes another function as a parameter) that goes through a list checking which element fulfills certain boolean condition. I don't quite understand its definition: filter:: (a->Bool)->[a]->[a] filter p [] = [] filter p (x:y) | p x = x:filter p y | otherwise = filter p y I understand that if I pass an empty list to the function, it would just return an empty list, but how do I read the last two lines?

  • How to get the current exception without having passing the variable?

    - by Pierre-Alain Vigeant
    I am looking for a way to retrieve the current exception without having to pass it as a variable. Suppose the following code public void MakeItFail() { try { throw new FailException(); } catch // Yes I'm aware that this shouldn't be done, but I don't want to go through all the code base and change it { ShowMessage("An error occured"); } } public void ShowMessage(string message) { // How can I retrieve the exception here } In the watch window, I can use $exception to get the current exception. Is there is a code equivalent?

  • How to listen for file system changes MAC - kFSEventStreamCreateFlagWatchRoot

    - by Cocoa Newbie
    Hi All, I am listening for Directory and disk changes in a COCOA project using FSEvents. I need to get events when a root folder is renamed or deleted. So, I passed kFSEventStreamCreateFlagWatchRoot while creating the FSEventStream.But even if I delete or rename the root folder I am not getting corresponding FSEventStreamEventFlags. Any idea what could possibly be the issue. I am listening for changes in a USB mounted device. I used both FSEventStreamCreate and FSEventStreamCreateRelativeToDevice. One thing I notices is when I try with FSEventStreamCreate I get the following error message while creating FSEventStream: (CarbonCore.framework) FSEventStreamCreate: watch_all_parents: error trying to add kqueue for fd 7 (/Volumes/NO NAME; Operation not supported) But with FSEventStreamCreateRelativeToDevice there are no errors but still not getting kFSEventStreamEventFlagRootChanged in event flags. Also, while creation using FSEventStreamCreateRelativeToDevice apple say's if I want to listen to root path changes pass emty string "". But I am not able to listen to root path changes by passing empty string. But when I pass "/" it works. But even for "/" I do not get any proper FSEventStreamEventFlags. I am pasting the code here: -(void) subscribeFileSystemChanges:(NSString*) path { PRINT_FUNCTION_BEGIN; // if already subscribed then unsubscribe if (stream) { FSEventStreamStop(stream); FSEventStreamInvalidate(stream); /* will remove from runloop */ FSEventStreamRelease(stream); } FSEventStreamContext cntxt = {0}; cntxt.info = self; CFArrayRef pathsToWatch = CFArrayCreate(NULL, (const void**)&path, 1, NULL); stream = FSEventStreamCreate(NULL, &feCallback, &cntxt, pathsToWatch, kFSEventStreamEventIdSinceNow, 1, kFSEventStreamCreateFlagWatchRoot ); FSEventStreamScheduleWithRunLoop(stream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); FSEventStreamStart(stream); } call back function: static void feCallback(ConstFSEventStreamRef streamRef, void* pClientCallBackInfo, size_t numEvents, void* pEventPaths, const FSEventStreamEventFlags eventFlags[], const FSEventStreamEventId eventIds[]) {? char** ppPaths = (char**)pEventPaths; int i; for (i = 0; i < numEvents; i++) { NSLog(@"Event Flags %lu Event Id %llu", eventFlags[i], eventIds[i]); NSLog(@"Path changed: %@", [NSString stringWithUTF8String:ppPaths[i]]); } } Thanks a lot in advance.

If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.

  • How do faces in .obj work?

    - by Adl
    Hi When parsing an .obj-file, with vertices and vertex-faces, it is easy to pass the vertices to the shader and the use glDrawElements using the vertex-faces. When parsing an .obj-file, with vertices and texture-coordinates, another type of face occur: texture-coordinate faces. When displaying textures, apart from loading images, binding them and passing texture coordinates into the parser, how to use the texture-coordinate faces? They differ from the vertex-faces and I suppose that the texture-coordinate faces have a purpose when displaying textures? Regards Niclas

  • Matrix "Zigzag" Reordering

    - by fbrereto
    I have an NxM matrix in Matlab that I would like to reorder in similar fashion to the way JPEG reorders its subblock pixels: (referenced from here) I would like the algorithm to be generic such that I can pass in a 2D matrix with any dimensions. I am a C++ programmer by trade and am very tempted to write an old school loop to accomplish this, but I suspect there is a better way to do it in Matlab.

  • Passing a parameter to ant from CruiseControl Dashboard

    - by MSUDrew
    I am working on incorporating CruiseControl into my teams build process. What we need is a way to pass a Clearcase view name into the ant script so it knows what view to use when building. Sometimes a developer needs to create a build that is used for their testing only and not on the main integration branch. Is there a way to do this?
