  • Android SurfaceView/Canvas flickering after trying to clear it

    - by Mark D
    So I am trying to clear the Canvas using canvas.drawColor(Color.BLACK) but if I just call this once, the display flickers and displays the old drawing which should have been covered up by the drawColor. Here is the important bits of my code - public void update() { //This method is called by a Thread Canvas canvas = holder.lockCanvas(null); if (canvas != null) { onDraw(canvas); } holder.unlockCanvasAndPost(canvas); } @Override protected void onDraw(Canvas canvas) { if (toClear) { canvas.drawColor(Color.BLACK); //if this is not set to change back to false, it does not flicker toClear = false; } //Draw some objects that are moving around } public void clearScreen() { //This method is called when the user pressed a button toClear = true; } After Googling around a litte, I heard about double buffering but came to the understanding that lockCanvas() and unlockCanvasAndPost() should handle this for me. What is going wrong here?

  • Access shell methods in controller? Cake PHP 1.3

    - by anonymous coward
    I wrote a shell method in CakePHP 1.3 that has a return value. I'd like to be able to access that method from within a controller, so that I can pass its return value into the View. I'm not sure how to access those methods appropriately from within the controller. Have I done it wrong? I could easily duplicate the code, but I'd like to "keep it DRY", and the actual functionality, I believe, doesn't belong with this particular controller - I just need it's return value in this particular view.

  • 2D Game Character Animation in iPhone - How is it done?

    - by Shnitzel
    What I mean is, do animators work on an animation in say Flash (or some other kind of key frame animation program) and then export it to the iphone somehow? For example, say I am an animator and I want to create a person waving for an iphone game. What type of external program would I use and then what libraries on the iphone sdk would I use to load them in?

  • WPF Application with Database.

    - by mike
    Hi, i would like to or need to use a database for my wpf project. It has to store "person" "team" "goals" and maybe 2 more things, nothing very big. Ive already used (worked) with databases in java / php (postgresql), but is there maybe an "easier" way to store the things.. i mean if the db is going to be big than i could use (postgre or mysql), but this one would be small.

  • C# code cleaning/auditing tool (stand-alone outside of the IDE).

    - by lucidquiet
    Does anyone know of a stand-alone tool for C# code cleaning/auditing that can run outside of Visual Studio IDE so as to be part of a build. Or if that isn't possible can someone provide some guidance as to how to make Visual Studio part of a build process -- by that I mean it would be nice to run the IDE's Sort and Remove unused using statements on all files as part of the build, but even better would be an exe that can read the .sln, or .csproj and do the job as part of build system. Thanks, L-

  • HTMLtags in input field

    - by megapool020
    I have a question about inserting values into an input field from my MYSQL DB. First I have a form to save data from an inputfield to the database. An extra script filters diacrits Á=&Aacute; to html code. So Állo will be saved like &Aacute;llo When I insert the data from the DB to a 'div' it shows Állo. When I insert the data into a input field it shows &Aacute;llo What am I doing wrong I use JQUERY to save data to the DB with the $.post method without pagerefresh. I also get the data from the DB with JQUERY $.post method without pagerefresh. Hope somebody can help.

  • Programmatically Setting the Version of a Window's Service on the ProjectInstaller

    - by user302004
    I have a Windows Service created in Visual Studio 2005 in C#. I have a setup project and a ProjectInstaller class. I also have code to programmatically get the version from the AssemblyFileVersionAttribute. I need to figure out where I set the version that I've obtained (and where this code should go). I tried placing it in the InitializeComponent method on ProjectInstaller.Designer.cs and then appending the version to serviceInstaller1.DisplayName and serviceInstaller1.ServiceName. This didn't work and you're not supposed to modify the contents of this method. Any ideas?

  • Can I reproduce Scala's behavior for == ?

    - by JPP
    In Programming in Scala, I can read that the == operator behaves as if it was defined like this: final def == (that: Any): Boolean = if (null eq this) {null eq that} else {this equals that} But there must actually be compiler magic to avoid null pointer exceptions, right? Is there any way for me to replicate this behavior with pure Scala; i.e., have an operator/method return one thing if the receiver is null and another one if it isn't? What I mean is an actual implementation of null eq this. I suppose I can write a "pimp" and then define the method on the wrapper class, but is there a more direct way to do this?

  • QuickTime movie disappearing from Javascript when scrolled offscreen in Firefox?

    - by c-had
    I have a web page I'm creating that uses Javascript to control an embedded QuickTime player. I add the QuickTime movie to the page using the AC_QuickTime.js file from Apple (as described here - http://developer.apple.com/mac/library/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML_Document/ScriptingHTML.html#//apple_ref/doc/uid/TP40001525-2-SW1 ). Everything seems to be working fine - I can call methods on the QuickTime movie and control its playback (as well as get the current timestamp). The problem is that in Firefox, when I scroll down such that the QuickTime player is no longer visible, I get the following error every time I try to call a method on the QuickTime movie: Error calling method on NPObject! This does not occur in Safari. Why is this happening, and is there any way to work around this?

  • Entity Framework: An object with the same key already exists in the objectstatemanager

    - by NealR
    I see that this question has been asked a lot, however I haven't found anything yet that solves the problem I'm having. Obviously i'm using the Entity Framework to perform an update to a record. Once the updates are complete, however, whenever I try to save I get the following error message: An object with the same key already exists in the objectstatemanager At first I was passing in a collection object from the view that contained a copy of the the ZipCodeTerritory model object zipToUpdate. I changed the code by pulling this object out and just sending in the relevant fields instead. However, I'm still getting the same error. What's also weird is the first time I run this code, it works fine. Any attempt after that I get the error. Controller Here is the code from the method calling the edit function public static string DescriptionOnly(ZipCodeIndex updateZip) { if (!string.IsNullOrWhiteSpace(updateZip.newEffectiveDate) || !string.IsNullOrWhiteSpace(updateZip.newEndDate)) { return "Neither effective or end date can be present if updating Territory Code only; "; } _updated = 0; foreach (var zipCode in updateZip.displayForPaging.Where(x => x.Update)) { ProcessAllChanges(zipCode, updateZip.newTerritory, updateZip.newStateCode, updateZip.newDescription, updateZip.newChannelCode); } _msg += _updated + " record(s) updated; "; return _msg; } And here is the method that actually does the updating. private static void ProcessAllChanges(ZipCodeTerritory zipToUpdate, string newTerritory, string newStateCode, string newDescription, string newChannelCode) { try { if (!string.IsNullOrWhiteSpace(newTerritory)) zipToUpdate.IndDistrnId = newTerritory; if (!string.IsNullOrWhiteSpace(newStateCode)) zipToUpdate.StateCode = newStateCode; if (!string.IsNullOrWhiteSpace(newDescription)) zipToUpdate.DrmTerrDesc = newDescription; if (!string.IsNullOrWhiteSpace(newChannelCode)) zipToUpdate.ChannelCode = newChannelCode; if (zipToUpdate.EndDate == DateTime.MinValue) zipToUpdate.EndDate = DateTime.MaxValue; _db.Entry(zipToUpdate).State = EntityState.Modified; _db.SaveChanges(); _updated++; } catch (DbEntityValidationException dbEx) { _msg += "Error during update; "; EventLog.WriteEntry("Monet", "Error during ProcessAllChanges: " + zipToUpdate.ToString() + " |EX| " + dbEx.Message); } catch (Exception ex) { _msg += "Error during update; "; EventLog.WriteEntry("Monet", "Error during ProcessAllChanges: " + zipToUpdate.ToString() + " |MESSAGE| " + ex.Message); } } EDIT The ZipCodeIndex object contains a list of ZipCodeTerritory model objects. These aren't being pulled from a linq query, but instead simply passed back to the controller from the view. Here is the signature of the controller method that starts the process: [HttpPost] public ActionResult Update(ZipCodeIndex updateZip, string button)
