  • C# equivalent of the C++ custom project Wizard

    - by gbjbaanb
    Hi., I have an existing wizard template created for VC++ from year back, ported to VS2008. It uses the custom wizard jscript/html templating system and DTE object. I've used this successfully for years, but now I want to create an entry for a standard C# project, I see there's no way to customise the C# project settings - the methods are for VC++ only. Is there something closely related to this for C# projects (or do I have to learn yet another way of creating a wizard for .net apps?)

  • NSDocument Subclass not closed by NSWindowController?

    - by Nathan Douglas
    Okay, I'm fairly new to Cocoa and Objective-C, and to OOP in general. As background, I'm working on an extensible editor that stores the user's documents in a package. This of course required some "fun" to get around some issues with NSFileWrapper (i.e. a somewhat sneaky writing and loading process to avoid making NSFileWrappers for every single document within the bundle). The solution I arrived at was to essentially treat my NSDocument subclass as just a shell -- use it to make the folder for the bundle, and then pass off writing the actual content of the document to other methods. Unfortunately, at some point I seem to have completely screwed the pooch. I don't know how this happened, but closing the document window no longer releases the document. The document object doesn't seem to receive a "close" message -- or any related messages -- even though the window closes successfully. The end result is that if I start my app, create a new document, save it, then close it, and try to reopen it, the document window never appears. With some creative subclassing and NSLogging, I managed to figure out that the document object was still in memory, and still attached to the NSDocumentController instance, and so trying to open the document never got past the NSDocumentController's "hmm, currently have that one open" check. I did have an NSWindowController and NSDocumentController instance, but I've purged them from my project completely. I've overridden nearly every method for NSDocument trying to find out where the issue is. So far as I know, my Interface Builder bindings are all correct -- "Close" in the main menu is attached to "performClose:" of the First Responder, etc, and I've tried with fresh unsullied MainMenu and Document xibs as well. I thought that it might be something strange with my bundle writing code, so I basically deleted it all and started from scratch, but that didn't seem to work. I took out my init method overrides, and that didn't help either. I don't have the source of any simple document apps here, so I didn't try the next logical step (to substitute known-working code for mine in the readfromurl and writetourl methods). I've had this problem for about sixteen hours of uninterrupted troubleshooting now, and needless to say, I'm at the end of my rope. If I can't figure it out, I guess I'm going to try the project from scratch with a lot more code and intensity based around the bundle-document mess. Any help would be greatly appreciated.

  • Built-in precedence in Expression Trees for math?

    - by jdk
    I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it (e.g. maybe through helper methods or classes)? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

  • Odd ActiveRecord model dynamic initialization bug in production

    - by qfinder
    I've got an ActiveRecord (2.3.5) model that occasionally exhibits incorrect behavior that appears to be related to a problem in its dynamic initialization. Here's the code: class Widget < ActiveRecord::Base extend ActiveSupport::Memoizable serialize :settings VALID_SETTINGS = %w(show_on_sale show_upcoming show_current show_past) VALID_SETTINGS.each do |setting| class_eval %{ def #{setting}=(val); self.settings[:#{setting}] = (val == "1"); end def #{setting}; self.settings[:#{setting}]; end } end def initialize_settings self.settings ||= { :show_on_sale => true, :show_upcoming => true } end after_initialize :initialize_settings # All the other stuff the model does end The idea was to use a single record field (settings) to persist a bunch of configuration data for this object, but allow all the settings to seamlessly work with form helpers and the like. (Why this approach makes sense here is a little out of scope, but let's assume that it does.) Net-net, Widget should end up with instance methods (eg #show_on_sale= #show_on_sale) for all the entires in the VALID_SETTINGS array. Any default values should be specified in initialize_settings. And indeed this works, mostly. In dev and staging, no problems at all. But in production, the app sometimes ends up in a state where a) any writes to the dynamically generated setters fail and b) none of the default values appear to be set - although my leading theory is that the dynamically generated reader methods are just broken. The code, db, and environment is otherwise identical between the three. A typical error message / backtrace on the fail looks like: IndexError: index 141145 out of string (eval):2:in []=' (eval):2:inshow_on_sale=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:in send' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:in each' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2634:in `update_attributes!' ...(then controller and all the way down) Ideas or theories as to what might be going on? My leading theory is that something is going wrong in instance initialization wherein the class instance variable settings is ending up as a string rather than a hash. This explains both the above setter failure (:show_on_sale is being used to index into the string) and the fact that getters don't work (an out of bounds [] call on a string just returns nil). But then how and why might settings occasionally end up as a string rather than hash?

  • Spring MVC Best Practice Handling Unrecoverable Exceptions In Controller

    - by jboyd
    When you have a controller that does logic with services and DAO's that may throw an unrecoverable exception, what is the best practice in dealing with those method calls? Currently an app I'm working on has very lengthy try catch methods that simply err.out exception messages, this doesn't seem very robust and I think that this code smells, is there any cookie cutter best practice for handling this in spring-mvc?

  • Website Development moving to Image Hosting

    - by Drew
    We are moving over to using Akamai for all of our large static content so far just flash but are planning to include images, css, and js files in that list. I am curious what methods others employ to switch all of their local/relative paths to using an external hosting company. Also, how they continue to develop their site so that developers can make changes in development without it having to be pushed to their external hosting servers.

  • 'abstract class' versus 'normal class' for a reusable library

    - by Greg
    I'm developing a reusable library and have been creating abstract classes, so the client can then extend from these. QUESTION: Is there any reason in fact I should use an abstract class here as opposed to just a normal class? Note - Have already decided I do not want to use interfaces as I want to include actual default methods in my library so the client using it doesn't have to write the code.

  • Java Annotations in eclipse Tooltip?

    - by reccles
    Is anyone aware of an eclipse plugin that updates the tooltip on hover over a method/class to include annotation information? There a few libraries we are using that have annotated methods and it would be handy if I could hover over the method and see what has been applied. I realize this would only work with annotations that have been retained but that is good enough.

  • WMI: Editing the Registry Remotely

    - by Quanta
    I'm trying to use the following code (poorly written, but it's just a proof of concept) to edit the registry of a computer on a domain. I have a domain account, and I've verified that the domain admin group is present in the local admin group on the machines I'm attempting to affect. I've connected to these other machines to perform other administrative type tasks, so I'm sure that I have administrative privileges on these hosts. All of StdRegProv's "get" methods work fine (http://msdn.microsoft.com/en-us/library/aa393664%28VS.85%29.aspx) but the "set" or "create" methods as well as check access all return "5" which is "Error_Access_Denied" according to winerror.h. So there's the problem: why do I get access denied when attempting to modify the registry? If anyone can help me figure this out, you'd have my utmost appreciation! I almost forgot, when I fire up Visual Studio in admin mode on my local machine and run the code against the local machine, it works flawlessly. If I don't start in admin mode on the local machine, the code fails, so I suspect there's a UAC problem maybe? using System; using System.Management; public class EditRemoteRegistry { public static void Main(string[] args) { ConnectionOptions options = new ConnectionOptions(); options.EnablePrivileges = true; options.Impersonation = ImpersonationLevel.Impersonate; options.Password = "password goes here"; //options.Authority = "my company's domain"; //options.Username = "Admin username"; ManagementScope scope = new ManagementScope("\\\\arbitraryhost\\root\\default", options); scope.Connect(); ManagementClass mc = new ManagementClass("StdRegProv"); ManagementBaseObject inParams = mc.GetMethodParameters("CreateKey"); inParams["hDefKey"] = (UInt32)2147483650; inParams["sSubKeyName"] = "Software\\Test"; ManagementBaseObject outParams = mc.InvokeMethod("CreateKey", inParams, null); //Should return a 0, but returns a 5, "Error_Access_Denied" Console.WriteLine("CreateKey Method returned " + outParams["returnValue"]); //This chunk works fine ManagementBaseObject inParams5 = mc.GetMethodParameters("GetDWORDValue"); inParams5["hDefKey"] = 2147483650; inParams5["sSubKeyName"] = "Software\\Test"; inParams5["sValueName"] = "testDWORDvalue"; ManagementBaseObject outParams5 = mc.InvokeMethod("GetDWORDValue", inParams5, null); Console.WriteLine("GetDWORDValue returned " + (UInt32)outParams5["returnValue"] + " "); Console.WriteLine((UInt32)outParams5["uValue"]); ManagementBaseObject inParams6 = mc.GetMethodParameters("SetStringValue"); inParams6["hDefKey"] = 2147483650; inParams6["sSubKeyName"] = "Software\\Test"; inParams6["sValueName"] = "TestStringValue"; inParams6["sValue"] = "Hello World!"; ManagementBaseObject outParams6 = mc.InvokeMethod("SetStringValue", inParams6, null); //Should return a 0, but returns a 5, "Error_Access_Denied" Console.WriteLine("SetStringValue returned " + outParams6["returnValue"]); Console.ReadKey(); } }

  • XBMC DVB-T and Played Video filling screen

    - by Tubs
    I have a small PC running as an XBMC attached to a Samsung le37m87bd. The PC isn't powerful enough to output a full HD 1080 image at 1920x1080 which is the TVs native resolution (about every 1/2 a second things go extra fast, I assume skipping frames), so I want to reduce this. Annoyingly, the TV does not support any other widescreen resolutions. (720 etc) If I use a a 4:3 image, the TV stretches it to be the 16:9, however, all 16:9 content is stretched sideways as XBMC is sending out a 4:3 image with a 16:9 image inside. Is there anyway I can force XBMC to compensate for this, ie stretch vertically so that black bars are removed, but not stretched horizontally?

  • Export multiple values from a single Combo Box? (Adobe Acrobat)

    - by metashockwave
    I'm trying to export 2 values from every single item from the combo box field. I have found two methods to insert items into a combo box: 1) insertItemAt http://www.verypdf.com/document/acrobat-forms-javascript/pg_0048.htm 2) setItems http://livedocs.adobe.com/acrobat_sdk/9/Acrobat9_HTMLHelp/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Acrobat9_HTMLHelp&file=JS_API_AcroJS.88.748.html but neither method allows two parameters (im always get "missing ) after argument list" error from the Acrobat JavaScript Debugger) Does anyone know of a better solution for this problem? Thanks!

  • Method/function overrides in Codeigniter

    - by pingu
    Hi guys, I want to override the validation_errors() method of the form helper in CodeIgniter for one controller only, so that it will display a single error message (as a sentence in plain english) instead of the detailed line item summary. I've tried defining a validation_errors() function in my controller, which is what I usually do with Silverstripe's Sapphire framework, but this won't with CI. What's the best way to override methods for a case by case basis?

  • Dropbox alternative with local sync support?

    - by srid
    I am currently using Dropbox. Just decided to sync my huge (about 5 GB) iTunes Library (music collection) in Dropbox. For that I must subscribe to their paid account. But before I do so, I'd like evaluate the alternatives. Is there an alternative that does this? Local LAN sync (eg: sync my huge music collection across computers in local network without uploading/downloading them to internet) The following would be nice (but not required): Native android client - so music will be made available in the Android music app / SDHC card Selective sync: sync particular folders / exclude certain folders on certain computers .. eg: excluding porn folder on work computers ;-) Just like Dropbox, it MUST work on 64-bit Windows, Linux and Mac. Know of any? (I am currently evaluating Spideroak. Boy, was it so complicated to use?)

  • How to code a keyboard button to switch between 2 modes?

    - by le.shep20
    Hi! i'm doing a project, i'm not going to details but i will simplify my idea, i'm using Morse Code ( dot and dash) and i have 2 methods: convert_MorseToChar() and Convert_MorseTonum() in the convert_MorseToChar() method there is swich to compare the input from a user which will be Morse codes and mapping it to characters: private String convert_MorseToChar(ref string Ch) { switch (Ch) { Case ".-": MorsetoChar = "a" break; Case "-...": MorsetoChar = "b" break; Case "-.-.": MorsetoChar = "c" break; Case "-..": MorsetoChar = "d" break; Case ".": MorsetoChar = "e" break; } } and the other method Convert_MorseToNum(), ues the SAME combinations of Morse codes but mapping them to numbers: private String Convert_MorseToNum(ref string Ch) { switch (Ch) { Case ".-": MorsetoChar = "1" break; Case "-...": MorsetoChar = "2" break; Case "-.-.": MorsetoChar = "3" break; Case "-..": MorsetoChar = "4" break; Case ".": MorsetoChar = "5" break; } } now the senario is: there are 2 Textbox, one the user will write Morse codes in it and the other is for the output. The user will write dot "." and dash "-" from the keyboard and press Enter then the program will go to ONE of the 2 methods to convert the Morse codes. Now what tells the program where to go to convert?? my question is: I want to create mode key to swich between 2 modes: MorseTochar and MorseToNum. i want the down arrow key to act like a mode, when a user press the down arrow then it the program will be in MorseToChar mode, when ever the user input the program directly use the method convert_MorseToChar to convert to characters. and when the user press the down arrow agian, the prohram will swich to MorseToNum mode here when ever the user input as morsecode, the program will directly use the method Convert_MorseToNum() to convert to numbers. HOW I CAN DO THAT Pleaaaas!!! help me! Please excuse my English, English is not my native language :)

  • Getting jerky backgrounds on Win7 on iMac 27'' 2560x1440

    - by JohnIdol
    I installed Win7 on bootcamp on my new iMac 27'' (ATI videocard) and everything was good until recently I noticed that the default win7 background (then one on the background on login) looked jerky. When I say jerky I mean the kind of jerky you get if you can't display enough colours, and instead of nice fading shades you just get stripes and jerky patterns. I am on native resolution but even if I go down to 1920x1080 I get the same. This might have happened after a firmware update but as I don't use windows very often I am not too sure it's what caused it. Oh, and when I am playing games everything looks OK (as in not jerky!). Any help appreciated!

  • Javascript Sandbox

    - by Louis
    I want to have developers write some custom apps for a site in Javascript but I want to sandbox it so they can't do anything naughty like redirect the user, set the body display to none etc etc. I have a namespace in Javascript where all the functions they'll ever need exist in there so I was thinking to create a sandbox would be a matter of: with(Namespace) { //App code goes here where they can only access Namespace.* } How is easy is it to get around this and what other methods can be done? Would rather not have to moderate every submitted app.

  • objective-c default init method for class?

    - by Alex
    Hello, I have two differing methods for initializing my objective-c class. One is the default, and one takes a configuration parameter. Now, I'm pretty green when it comes to objective-c, but I've implemented these methods and I'm wondering if there's a better (more correct/in good style) way to handle initialization than the way I have done it. Meaning, did I write these initialization functions in accordance with standards and good style? It just doesn't feel right to check for the existence of selfPtr and then return based on that. Below are my class header and implementation files. Also, if you spot anything else that is wrong or evil, please let me know. I am a C++/Javascript developer who is learning objective-c as hobby and would appreciate any tips that you could offer. #import <Cocoa/Cocoa.h> // class for raising events and parsing returned directives @interface awesome : NSObject { // silence is golden. Actually properties are golden. Hence this emptiness. } // properties @property (retain) SBJsonParser* parser; @property (retain) NSString* eventDomain; @property (retain) NSString* appid // constructors -(id) init; -(id) initWithAppId:(id) input; // destructor -(void) dealloc; @end #import "awesome.h" #import "JSON.h" @implementation awesome - (id) init { if (self = [super init]) { // if init is called directly, just pass nil to AppId contructor variant id selfPtr = [self initWithAppId:nil]; } if (selfPtr) { return selfPtr; } else { return self; } } - (id) initWithAppId:(id) input { if (self = [super init]) { if (input = nil) { input = [[NSString alloc] initWithString:@"a369x123"]; } [self setAppid:input]; [self setEventDomain:[[NSString alloc] initWithString:@"desktop"]]; } return self; } // property synthesis @synthesize parser; @synthesize appid; @synthesize eventDomain; // destructor - (void) dealloc { self.parser = nil; self.appid = nil; self.eventDomain = nil; [super dealloc]; } @end Thanks!
