  • Disallow private constructor invocation in friend function

    - by user2907032
    Is there any way to not allow private construction in friend function, In case we do have private constructor with friend function in our class. Only Static method should be responsible for object creation and other than this compiler should flash error message #include <iostream> #include <memory> using namespace std; class a { public: void see () { cout<<"Motimaa"; } static a& getinstance() { static a instance; return instance; } private: a() {}; friend void access(); }; void access () { a obj; obj.see();//still friend function can access } int main() { a::getinstance().see(); access(); return 1; }

  • Javascript setInterval and `this` solution

    - by Michael
    I need to access this from my setInterval handler prefs: null, startup : function() { // init prefs ... this.retrieve_rate(); this.intervalID = setInterval(this.retrieve_rate, this.INTERVAL); }, retrieve_rate : function() { var ajax = null; ajax = new XMLHttpRequest(); ajax.open('GET', 'http://xyz.com', true); ajax.onload = function() { // access prefs here } } How can I access this.prefs in ajax.onload ?

  • .htaccess stupid issue

    - by justnoone
    I have a server where I can only configure httpd using .htaccess, a cannot access global configuration. I want to rewrite almost every non-existing path to index.php, so I did something like: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?path=$1 [L,QSA] And that is ok. But another thing I want to do is to prevent access to path where I keep PHP files (I cannot store them somewhere else) which is for example /php. I would like that anything starting with /php rewrites to index.php?path=php... so I did something like: RewriteCond %{REQUEST_URI} ^/php.* RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] And that also would work ok if I had access to global configuration. In case of per-directory configuration, when I access /php it rewrites it to index.php?path=php and than puts directory name before that: /php/index.php?path=php. I read documentation and I realize that it uses internal redirects when per-directory confoguration is used. How can I avoid this behavior?

  • MVC, how view should be accessed from controller?

    - by Kirzilla
    Hello, I'm just learning MVC so you could find my question rather strange... My Controller have access to different shared objects through Container object passed to Controller's constructor. To access shared objects I should do $this-container-db to access Database adapter or $this-container-memcache to access Memcached adapter. I want to know should I put View object into Container with shared objects or no? From one side it is really comfortable to take view from this container, but this way I couldn't create multiple Views instances (for example, every time I'm calling Controller's method from View I should have one more View instance). What is the solution? How should I pass View object into Controller and/or how should I create new View instances from Controller? Thank you!

  • can bind successfully to the ldap server, but needs to know how to find user w/i AD

    - by Brad
    I create a login form to bind to the ldap server, if successful, it creates a session (which the user's username is stored within), then I go to another page that has session_start(); and it works fine. What I want to do now, is add code to test if that user is a member of a specific group. So in theory, this is what I want to do if(username session is valid) { search ldap for user -> get list of groups user is member of foreach(group they are member of) { switch(group) { case STAFF: print 'they are member of staff group'; $access = true; break; default: print 'not a member of STAFF group'; $access = false; break; } if(group == STAFF) { break; } } if($access == TRUE) { // you have access to the content on this page } else { // you do not have access to this page } } How do I do a ldap_search w/o binding? I don't want to keep asking for their password on each page, and I can't pass their password thru a session. Any help is appreciated.

  • Repository Pattern Standardization of methods

    - by Nix
    All I am trying to find out the correct definition of the repository pattern. My original understanding was this (extremely dubmed down) Separate your Business Objects from your Data Objects Standardize access methods in data access layer. I have really seen 2 different implementations. Implementation 1 : public Interface IRepository<T>{ List<T> GetAll(); void Create(T p); void Update(T p); } public interface IProductRepository: IRepository<Product> { //Extension methods if needed List<Product> GetProductsByCustomerID(); } Implementation 2 : public interface IProductRepository { List<Product> GetAllProducts(); void CreateProduct(Product p); void UpdateProduct(Product p); List<Product> GetProductsByCustomerID(); } Notice the first is generic Get/Update/GetAll, etc, the second is more of what I would define "DAO" like. Both share an extraction from your data entities. Which I like, but i can do the same with a simple DAO. However the second piece standardize access operations I see value in, if you implement this enterprise wide people would easily know the set of access methods for your repository. Am I wrong to assume that the standardization of access to data is an integral piece of this pattern ? Rhino has a good article on implementation 1, and of course MS has a vague definition and an example of implementation 2 is here.

  • .NET GDI+ image size - file codec limitations

    - by roygbiv
    Is there a limit on the size of image that can be encoded using the image file codecs available from .NET? I'm trying to encode images 4GB in size, but it simply does not work (or does not work properly i.e. writes out an unreadable file) with .bmp, .jpg, .png or the .tif encoders. When I lower the image size to < 2GB it does work with the .jpg but not the .bmp, .tif or .png. My next attempt would be to try libtiff because I know tiff files are meant for large images. What is a good file format for large images? or am I just hitting the file format limitations? Random r = new Random((int)DateTime.Now.Ticks); int width = 64000; int height = 64000; int stride = (width % 4) > 0 ? width + (width % 4) : width; UIntPtr dataSize = new UIntPtr((ulong)stride * (ulong)height); IntPtr p = Program.VirtualAlloc(IntPtr.Zero, dataSize, Program.AllocationType.COMMIT | Program.AllocationType.RESERVE, Program.MemoryProtection.READWRITE); Bitmap bmp = new Bitmap(width, height, stride, PixelFormat.Format8bppIndexed, p); BitmapData bd = bmp.LockBits(new Rectangle(0, 0, bmp.Width, bmp.Height), ImageLockMode.ReadWrite, bmp.PixelFormat); ColorPalette cp = bmp.Palette; for (int i = 0; i < cp.Entries.Length; i++) { cp.Entries[i] = Color.FromArgb(i, i, i); } bmp.Palette = cp; unsafe { for (int y = 0; y < bd.Height; y++) { byte* row = (byte*)bd.Scan0.ToPointer() + (y * bd.Stride); for (int x = 0; x < bd.Width; x++) { *(row + x) = (byte)r.Next(256); } } } bmp.UnlockBits(bd); bmp.Save(@"c:\test.jpg", ImageFormat.Jpeg); bmp.Dispose(); Program.VirtualFree(p, UIntPtr.Zero, 0x8000); I have also tried using a pinned GC memory region, but this is limited to < 2GB. Random r = new Random((int)DateTime.Now.Ticks); int bytesPerPixel = 4; int width = 4000; int height = 4000; int padding = 4 - ((width * bytesPerPixel) % 4); padding = (padding == 4 ? 0 : padding); int stride = (width * bytesPerPixel) + padding; UInt32[] pixels = new UInt32[width * height]; GCHandle gchPixels = GCHandle.Alloc(pixels, GCHandleType.Pinned); using (Bitmap bmp = new Bitmap(width, height, stride, PixelFormat.Format32bppPArgb, gchPixels.AddrOfPinnedObject())) { for (int y = 0; y < height; y++) { int row = (y * width); for (int x = 0; x < width; x++) { pixels[row + x] = (uint)r.Next(); } } bmp.Save(@"c:\test.jpg", ImageFormat.Jpeg); } gchPixels.Free();

  • PHP: Mapped Network Drives

    - by Abs
    Hello all, I have mapped a network drive to a computer in my home network. Now I am trying to access it via PHP - I did this quick test: echo opendir('Z:\\'); This gives me: Warning: opendir(Z:\) [function.opendir]: failed to open dir: No error in C:\wamp\www\webs\tester-function.php on line 3 What have I done wrong here? I don't want my users typing in the UNC path so is there a way to get the UNC path for them and maybe that will work when I try to access it? This is possible in Microsoft languages but I am not sure how to get PHP to do this - maybe using a cmd.exe command? Please note, the mapped drive does exist as I can see it and I can access it. It also does not appear to be a permissions problem as I am assuming it would of complained about this IF it could access that drive...right? Thanks all for any help

  • C# type safe and developer friendly list/collection technique

    - by Agile Noob
    I am populating a "Dictionary" with the results of an sp call. The key is the field name and the value is whatever value the sp returns for the field. This is all well and good but I'd like developers to have a predefined list of keys to access this list, for safety and documentation reasons. What I'd like to do is have something like an enum as a key for the dictionary so developers can safely access the list, but still have the ability to access the dictionary with a string key value. I am hoping to have a list of string values that I can access with an enum key AND a string key. Please make sure any suggestions are simple to implement, this is not the kind of thing I'm willing to build a lot of overhead to implement.

  • using JDBC with persistence.xml

    - by moshe shamy
    I am building a framework that manage the access to the database. the framework getting tasks from the user and handle a connection pooling that manage the access to the database. the user just send me SQL commands. One of the feature that i would like to support is working with JPA, in this case i will provide entity manager. in some cases i would like to provide JDBC access as well as JPA access. the arguments for the database are written in XML file. so for JPA i need to write the property in persistence.xml so it will be not so smart to write again the same arguments for JDBC. do you know if i can get the arguments of the database from persistence.xml, do you know if there is a source code that do it. or should i parse persistence.xml by myself?

  • C# : Console.Read() does not get the "right" input

    - by Daemonfire3002nd
    Hi there, I have the following code: The actual problem is the "non-quoted" code. I want to get the player amount (max = 4), but when I ask via Console.Read() and I enter any Int from 1 to 4 I get as value: 48 + Console.Read(). They only thing how I can get the "real" input is using Console.ReadLine(), but this does not give me an Integer, no it returns a string, and actually do not know how to convert String (Numbers) to Integers in C#, because I am new, and because I only found ToString() and not ToNumber. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace eve_calc_tool { class Program { int players; int units; int active_units; int inactive_units; int finished_units; int lastDiceNumber = 0; bool game_state; public static void Main(string[] args) { int count_game = 0; //Console.Title = "Mensch ärger dich nicht"; //Console.WriteLine("\tNeues Spiel wird"); //Console.WriteLine("\t...geladen"); //System.Threading.Thread.Sleep(5000); //Console.Clear(); //Console.WriteLine("Neues Spiel wird gestartet, bitte haben sie etwas Geduld"); //Console.Title = "Spiel " + count_game.ToString(); //Console.Clear(); //string prevText = "Anzahl der Spieler: "; //Console.WriteLine(prevText); string read = Console.ReadLine(); /*Program game = new Program(); game.players = read; game.setPlayers(game.players); if (game.players > 0 && 5 > game.players) { game.firstRound(); }*/ string readagain = read; Console.ReadLine(); } /* bool setPlayers(int amount) { players = amount; if (players > 0) { return true; } else { return false; } } bool createGame() { inactive_units = units = getPlayers() * 4; active_units = 0; finished_units = 0; game_state = true; if (game_state == true) { return true; } else { return false; } } int getPlayers() { return players; } private static readonly Random random = new Random(); private static readonly object syncLock = new object(); public static int RandomNumber(int min, int max) { lock (syncLock) { // synchronize return random.Next(min, max); } } int rollDice() { lastDiceNumber = RandomNumber(1,6); return lastDiceNumber; } int firstRound() { int[] results = new int[getPlayers()]; for (int i = 0; i < getPlayers(); i++) { results[i] = rollDice(); } Array.Sort(results); return results[3]; } */ } }

  • Amazon S3 permissions

    - by Joe
    Trying to understand S3...How do you limit access to a file you upload to S3? For example, from a web application, each user has files they can upload, but how do you limit access so only that user has access to that file? It seems like the query string authentication requires an expiration date and that won't work for me, is there another way to do this?

  • Android asking for unneeded permissions

    - by steveo225
    I have an Android widget that needs internet access, fine and coarse permissions only. However, when I install the apk file, it says it also needs access to read the phone state and identity, and access to storage. It doesn't need access to either, and the only permissions that are in the mainfest are: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> Any ideas on why this is happening? Thanks for the help.

  • Drupal menu permissions question

    - by Luke
    I'm creating an admin module for my client that gives then access to some administration functionality concerning their content. I'm starting off my adding some permissions in my module by implementing hook_perm: function mymodule_perm() { return array( 'manage projects', ); } I can then create my menu by adding to the admin section that already exists: function mymodule_menu() { $items['admin/projects'] = array( 'title' => 'Projects', 'description' => 'Manage your projects.', 'page callback' => 'manage_projects_overview', 'access callback' => 'user_access', 'access arguments' => array('manage projects'), 'type' => MENU_NORMAL_ITEM, 'weight' => -100, ); $items['admin/projects/add'] = array( 'title' => 'Add project', 'access arguments' => array('manage projects'), 'page callback' => 'mymodule_projects_add', 'type' => MENU_NORMAL_ITEM, 'weight' => 1, ); return $items; } This will add a Projects section to the Administration area with an Add project sub section. All good. The behavior I want is that my client can only see the Projects section when they log in. I've accomplished this by ticking the "manage projects" permission for authenticated users. Now to give my client actual access to the Administration area I also need to tick "access administration pages" under the "system module" in the users permissions section. This works great, when I log in as my client I can only see the Projects section in the Administration area. There is one thing though, I my Navigation menu shown in the left column I can see the following items: - Administer - Projects - Content management - Site building - Site configuration - User management I was expecting only the see Administer and Projects, not the other ones. When I click e.g. Content Management I get a Content Management titled page with no options. Same for Site Building, Site Configuration and User Management. What's really odd is that Reports is not being shown which is also a top level Administration section. Why are these other items, besides my Projects section, being shown and how can I make them stop from appearing if I'm not logged in as administrator?

  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();

  • HTTP 401.3 when PUT, DELETE to ADO.NET Data Service (.svc)

    - by Nate
    I have an ADO.NET Data Service (we'll call it service.svc). When I deploy it to an IIS 6 site with Integrated Windows Authentication turned on, all requests (GET, POST, PUT, and DELETE) work fine for me, because I am an administrator on the box. However, when a non-admin user hits the service, only GET and POST requests work. When they try a PUT or DELETE request, they get an HTTP 401.3 "Access is Denied" error: "Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists). Ask the web server's administrator to give you access to '...\service.svc'." If I give the "Authenticated Users" local group write access to the .svc file, everything works as it should, but I really don't want to do this (and don't think I should have to do this to get this to work). In fact, I'm confused as to why changing the file permissions would affect this at all, but it definitely seems to be the problem. I've found a couple of different suggestions to fix somewhat similar problems in the Microsoft forums (Here, and I would post more links, but am being told that new users can only post one link in a post), but none of the solutions help. Any help is much appreciated. I am certainly no IIS expert, and this one has got me stumped.

  • Communication between Multiple Threads in a WPF Application

    - by Robert
    I'm creating a WPF application that uses a custom object to populate all the controls. The constructor of that object is initiated by an EventHandler that waits for an API. The problem I'm having is when I try to access any information from that object using a button for example, it returns an error saying "The calling thread cannot access this object because a different thread owns it". I'm assuming this is because the EventHandler creates a new thread which doesn't allow the Main Thread to have access to it. Any ideas on how to get around this? I'm basically having the error "The calling thread cannot access this object because a different thread owns it" when trying to get or set a CollectionViewSource.

  • Does "I securely erased my drive" really work with Truecrypt partitions?

    - by TheLQ
    When you look at Truecrypt's Plausible Deniability page it says that one of the reasons for partition with solely random data is that you securely erased your drive. But what about the partition table with full disk encryption? How can you explain why the partition table says there's a partition of unknown type (With my limited knowledge of partition tables I think that they store all the partition filesystem types) and with solely random data? It seems that if your going to securely erase the drive you would destroy everything, including the partition table. And even if you just wiped the partition, the partition table would still say that the partition was originally NTFS, which it isn't anymore. Does the "I securely erased my drive" excuse still work here? (Note: I know that there's hidden truecrypt volumes, but I'm avoiding them due to the high risk of data loss)

  • Does the .NET Framework need to be reoptimized after upgrading to a new CPU microarchitecture?

    - by Louis
    I believe that the .NET Framework will optimize certain binaries targeting features specific to the machine it's installed on. After changing the CPU from an Intel Nehalem to a Haswell chip, should the optimization be run again manually? If so, what is the process for that? Between generations here are some notable additions: Westmere: AES instruction set Sandy Bridge: Advanced Vector Extensions Ivy Bridge: RdRand (hardware random number generator), F16C (16-bit Floating-point conversion instructions) Haswell: Haswell New Instructions (includes Advanced Vector Extensions 2 (AVX2), gather, BMI1, BMI2, ABM and FMA3 support) So my, albeit naive, thought process was that the optimizations could take advantage of these in general cases. For example, perhaps calls to the Random library could utilize the hardware-RNG on Ivy Bridge and later models.

  • Pipelining String in Powershell

    - by ChvyVele
    I'm trying to make a simple PowerShell function to have a Linux-style ssh command. Such as: ssh username@url I'm using plink to do this, and this is the function I have written: function ssh { param($usernameAndServer) $myArray = $usernameAndServer.Split("@") $myArray[0] | C:\plink.exe -ssh $myArray[1] } If entered correctly by the user, $myArray[0] is the username and $myArray[1] is the URL. Thus, it connects to the URL and when you're prompted for a username, the username is streamed in using the pipeline. Everything works perfectly, except the pipeline keeps feeding the username ($myArray[0]) and it is entered as the password over and over. Example: PS C:\Users\Mike> ssh xxxxx@yyyyy login as: xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyy's password: Access denied xxxxx@yyyyy's password: FATAL ERROR: Server sent disconnect message type 2 (protocol error): "Too many authentication failures for xxxxx" Where the username has been substituted with xxxxx and the URL has been substituted with yyyyy. Basically, I need to find out how to stop the script from piping in the username ($myArray[0]) after it has been entered once. Any ideas? I've looked all over the internet for a solution and haven't found anything.
