  • How to handle this "session failed to write file" error in PHP?

    - by alex
    I am using the Kohana 3 framework, and am using the native session driver. For some reason, occasionally the sessions fail to write to their file. Warning: session_start() [function.session-start]: open(/tmp/sess_*****, O_RDWR) failed: Permission denied (13) in /home/site/public_html/system/classes/kohana/session/native.php on line 27 I am pretty sure Kohana has its own in built error handler, but it is not triggered with this error (i.e. it shows up like a normal PHP error, not the Kohana error). Anyone that has ever used Kohana will notice this seems to have bypassed Kohana's error handling (perhaps set with set_error_handler()). Is there anyway to stop this error from appearing without switching from the native session (i.e. file based) driver? Should I just give good practice the boot and append an @ error suppressor to session_start() in the core code of Kohana? Should I relax the error_reporting()? Thanks

  • Using Classes / OOP in PHP

    - by Alex Demchak
    I'm pretty proficient with PHP, outside of OOP - which I am just now starting to jump in to. I've been watching videos and reading tutorials, but they are all still pretty confusing... If I have FILE 1 (class.time.php) class Time { function GetTime(){ $time = date('H:i:s'); printf($time); } } and then in a nother php page I've got FILE 2 (page.php) I can do include('class.time.php'); and then anywhere in this page I can then do $time = new Time; //Calling the class and setting the class to a variable $time->GetTime(); //This is BASICALLY saying (run the 'GetTime' function in the 'Time Class' My main question is, is the comment above (This is BASICALLY saying.....) correct? or is there a better way to think of it?

  • Java if/else behaving strangely

    - by Alex
    I'm a real newbie to java, so please excuse me if this is a hopelessly straightforward problem. I have the following from my java game server: // Get input from the client DataInputStream in = new DataInputStream (server.getInputStream()); PrintStream out = new PrintStream(server.getOutputStream()); disconnect=false; while((line = in.readLine().trim()) != null && !line.equals(".") && !line.equals("") && !disconnect) { System.out.println("Received "+line); if(line.equals("h")){ out.println("h"+EOF); // Client handshake System.out.println("Matched 1"); }else if (line.equals("<policy-file-request/>")) { out.println("..."+EOF); // Policy file System.out.println(server.getInetAddress()+": Policy Request"); disconnect=true; System.out.println("Matched 2"); }else if(line.substring(0,3).equals("GET")||line.substring(0,4).equals("POST")){ out.println("HTTP/1.0 200 OK\nServer: VirtuaRoom v0.9\nContent-Type: text/html\n\n..."); // HTML status page disconnect=true; System.out.println("Matched 3"); } else { System.out.println(server.getInetAddress()+": Unknown command, client disconnected."); disconnect=true; System.out.println("Matched else"); } } server.close(); First of all, the client sends an "h" packet, and expects the same back (handshake). However, I want it to disconnect the client when an unrecognised packet is received. For some reason, it responds fine to the handshake and HTML status request, but the else clause is never executed when there's an unknown packet. Thanks

  • OpenID login on local development server for google app engine

    - by Alex Jeffery
    Are you able to use open id to log into the local development server with google app engine sdk version 1.4.1 and python 2.5? When I execute this self.redirect(users.create_login_url(continue_url, None, openid_url)) I get redirected to http://localhost/_ah/login rather than the openid url. The openid url and continue url are valid. My app.yaml looks like this - url: /_ah/login_required script: do_openid_login.py - url: /users/(.*) script: routers/user_router.py login: required If I browse to http://localhost/users/ I am also redirected to http://localhost/_ah/login rather than http://localhost/_ah/login_required Is there a config issue or does openid not work locally?

  • Create an Action<T> to "set" a property, when I am provided with the LINQ Expression for the "get"

    - by Alex
    I'd like to be able to generate a compiled expression to set a property, given the lambda expression that provides the "get" method for a property. Here's what I'm looking for: public Action<int> CreateSetter<T>(Expression<Func<T, int>> getter) { // returns a compiled action using the details of the getter expression tree, or null // if the write property is not defined. } I'm still trying to understand the various types of Expression classes, so if you can point me in the right direction that would be great.

  • Have a div cling to top of screen if scrolled down past it

    - by Alex
    I have a div which, when my page is first loaded, is about 100px from the top (it holds some buttons etc. for the page). When a user scrolls past it, I would like the div to "follow" the user in that it attaches to the top of the screen. When the user returns to the top of the page, I want it back in its original position. Visualization - xxxxx is the div: Default (page load) User vertically scrolled well past it --------- --------- | | |xxxxxxx| < after div reaches top of screen when |xxxxxxx| | | page is scrolled vertically, it stays | | | | there --------- ---------

  • Using SimpleDB (with SimpleSavant) with POCO / existing entities, not attributes on my classes

    - by alex
    I'm trying to use Simple Savant within my application, to use SimpleDB I currently have (for example) public class Person { public Guid Id { get; set; } public string Name { get; set; } public string Description { get; set; } public DateTime DateOfBirth { get; set; } } To use this with Simple Savant, i'd have to put attributes above the class declaration, and property - [DomainName("Person")] above the class, and [ItemName] above the Id property. I have all my entities in a seperate assembly. I also have my Data access classes an a seperate assembly, and a class factory selects, based on config, the IRepository (in this case, IRepository I want to be able to use my existing simple class - without having attributes on the properties etc.. In case I switch out of simple db, to something else - then I only need to create a different implementation of IRepository. Should I create a "DTO" type class to map the two together? Is there a better way?

  • How do I overwrite the functionality of the home button?

    - by Alex
    Essentially, I just want to change the home button from just hiding my app to killing the activity that is on the screen. I thought about writing a broadcast receiver that kills the activity, but I'm not sure how to kill the activity from the receiver. How do I change the functionality of the home button to "finish" the specific activity? Thanks

  • Strange Rendering in Firefox

    - by Alex
    I've just noticed when loading my client's page (http://habbopfm.com/) in Firefox, that it renders what looks like a rectangle is pushed down a few pixels. It's difficult to describe, but imagine you took a screenshot of the page, opened it in Photoshop, selected a rectangle and moved it down a bit. IE and Safari don't appear to do this - I'm assuming this is a browser glitch, not a problem with the code. Can anyone confirm what causes this? Below is a screenshot taken of the issue: http://habbopfm.com/problem.png One other thing is that it only does this once the page has finished loading. While it is loading, it looks fine.

  • Question about inserting/updating rows with SQL Server (ASP.NET MVC)

    - by Alex
    I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

  • Creating a new variable in C from only part of an existing u_char

    - by Alex Kloss
    I'm writing some C code to parse IEEE 802.11 frames, but I'm stuck trying to create a new variable whose length depends on the size of the frame itself. Here's the code I currently have: int frame_body_len = pkt_hdr->len - radio_hdr->len - wifi_hdr_len - 4; u_char *frame_body = (u_char *) (packet + radio_hdr->len + wifi_hdr_len); Basically, the frame consists of a header, a body, and a checksum at the end. I can calculate the length of the frame body by taking the length of the packet and subtracting the length of the two headers that appear before it (radio_hdr->len and wifi_hdr_len respectively), plus 4 bytes at the end for the checksum. However, how can I create the frame_body variable without the trailing checksum? Right now, I'm initializing it with the contents of the packet starting at the position after the two headers, but is there some way to start at that position and end 4 bytes before the end of packet? packet is a pointer to a u_char, if it helps. I'm a new C programmer, so any and all advice about my code you can give me would be much appreciated. Thanks!

  • Why 10675199.02:48:05.4775807 TimeSpan Maximum for CompilationSection?

    - by Alex
    I was looking at the metadata for System.Web.Configuration.CompilationSection, and noticed the following attribute on the TimeSpan BatchTimeout property: [TimeSpanValidator(MinValueString = "00:00:00", MaxValueString = "10675199.02:48:05.4775807")] Could someone explain why this is the allowed max value? TimeSpan itself has an upper limit, so why would there be another value validation, and why this number?

  • why doesnt this program print?

    - by Alex
    What I'm trying to do is to print my two-dimensional array but i'm lost. The first function is running perfect, the problem is the second or maybe the way I'm passing it to the "Print" function. #include <stdio.h> #include <stdlib.h> #define ROW 2 #define COL 2 //Memory allocation and values input void func(int **arr) { int i, j; arr = (int**)calloc(ROW,sizeof(int*)); for(i=0; i < ROW; i++) arr[i] = (int*)calloc(COL,sizeof(int)); printf("Input: \n"); for(i=0; i<ROW; i++) for(j=0; j<COL; j++) scanf_s("%d", &arr[i][j]); } //This is where the problem begins or maybe it's in the main void print(int **arr) { int i, j; for(i=0; i<ROW; i++) { for(j=0; j<COL; j++) printf("%5d", arr[i][j]); printf("\n"); } } void main() { int *arr; func(&arr); print(&arr); //maybe I'm not passing the arr right ? }

  • Making swedish characthers show properly in Windows Command Prompt using Python in Notepad++

    - by Alex
    The title explains it well. I have set up Notepad++ to open the python script in the command prompt when I press F8 but all Swedish characters looks messed up when opening in CMD but perfectly fine in e.g IDLE. This simple example code: #!/usr/bin/env python #-*- coding: UTF-8 -*- print "åäö" Looks like this. As you can see the output of the bath file I use to open Python in cmd below shows the characthers correctly but not the python script above it. How do i fic this?

  • Scala puts precedence on implicit conversion over "natural" operations... Why? Is this a bug? Or am

    - by Alex R
    This simple test, of course, works as expected: scala var b = 2 b: Int = 2 scala b += 1 scala b res3: Int = 3 Now I bring this into scope: class A(var x: Int) { def +=(y:Int) { this.x += y } } implicit def int2A(i:Int) : A = new A(i) I'm defining a new class and a += operation on it. I never expected this would affect the way my regular Ints behave. But it does: scala var b:Int = 0 b: Int = 0 scala b += 1 scala b res29: Int = 0 scala b += 2 scala b res31: Int = 0 Scala seems to prefer the implicit conversion over the natural += that is already defined to Ints. That leads to several questions... Why? Is this a bug? Is it by design? Is there a work-around (other than not using "+=")? Thanks

  • C# - Wait to finish before doing the next task

    - by Alex Ogden
    i have a server application with a richtextbox as the console text basically. The problem is, i have start, restart and stop buttons - But my restart button doesn't work. Heres my code for the restart button: consoletxt("RESTART", "Restarting Server..."); statuslabel1.Text = "Restarting"; statuslabel1.ForeColor = Color.Orange; statuslabel2.Text = "Restarting"; statuslabel2.ForeColor = Color.Orange; command("stop"); //The performclick just starts the server startbtn.PerformClick(); statuslabel1.Text = "Online"; statuslabel1.ForeColor = Color.DarkGreen; statuslabel2.Text = "Online"; statuslabel2.ForeColor = Color.DarkGreen; consoletxt("RESTART", "Restart completed, server online!"); However, the output is this: 2012-04-01 11:32:12 [RESTART] Restarting Server... 2012-04-01 11:32:12 [RESTART] Restart completed, server online! 2012-04-01 11:32:12 [INFO] CONSOLE: Stopping the server.. 2012-04-01 11:32:12 [INFO] Stopping server So, it says that the restart has finished in the text - but it hasn't - all it has done is stop the server. Please can sombody explain to me how to do this properly? Thanks!
