  • Static Variables somehow maintaining state?

    - by gfoley
    I am working on an existing project, setup by another coder. I'm having some trouble understanding how state is being maintained between pages. There is a Class library which has some helper objects. Mostly these objects are just used for there static methods and rarely instantiated or inherited. This is an example class I'm testing with. public sealed class Application { public static string Test; } Now when i run something like the following in the base class of my page, I would expect the result to be "1: 2:Test" all the time (note that "1" is empty), but strangly its only this way the first time it is run. Then every time afterwards its "1:Test 2:Test". Somehow its maintaining the state of the static variable between pages and being refreshed?? Response.Write("1:" + SharedLibrary.Application.Test); SharedLibrary.Application.Test = "Test"; Response.Write(" 2:" + SharedLibrary.Application.Test); I need to create more classes like this, but want to understand why this is occurring in the first place. Many Thanks

  • Powershell - Using variables in -Include filter

    - by TheD
    (again!) My final question for the night. I have a function which uses the Get-ChildItem to work out the newest file within a folder. The reason being I need to find the latest incremental backup in a folder and script an EXE to mount it. However, within this same folder there are multiple backup chains for all different servers: i.e. SERVER1_C_VOL_b001_i015.spi SERVER2_D_VOL_b001_i189.spi SERVER1_C_VOL_b002_i091.spi SERVER1_E_VOL_b002_i891.spi (this is the newest file created) I want only to look at SERVER1, look at only the C_VOL and look at only b001 - nothing else. I have all these seperate components: the drive letter, the Server Name, the b00X number stored in array. How then can I go and use the Get-ChildItem with the -Include filter to only look at: .spi SERVER1 C_VOL b001 Given I have all of these separate components in an array taken from a text file: Get-Content .\PostBackupCheck-TextFile.txt | Select-Object -First $i { $a = $_ -split ' ' ; $locationArray += "$($a[0]):\$($a[1])\$($a[2])" ; $imageArray += "$($a[2])_$($a[3])_VOL_b00$($a[4])_i$($a[5]).spi" } I then go onto try and filter then and then get stuck: $latestIncremental = Get-ChildItem -Path ${shadowProtectDataLocation}\*.* -Include *.spi | Sort-Object LastAccessTime -Descending | Select-Object -First 1 I have the .spi filtered, but how can I also just include the C (for volume), the number for the b00x and the server name. Thanks!

  • Google Map V3 Constants as Variables

    - by Beardy
    In the example below I am trying to update the map type depending on the value of the selected option type. Unfortunately it doesn't seem to load the maptype into the google.maps.MapTypeId which is frustrating. I have tried it as a string as well as var gmapsMapType = google.maps.MapTypeId.++maptype; and I feel I am missing something here. HTML <select id="maptype" name="maptype"> <option selected="selected" value="RoadMap">Road Map</option> <option value="Satellite">Satellite</option> <option value="Hybrid">Hybrid</option> <option value="Terrain">Terrain</option> </select> JQUERY var maptype = $('#maptype>option:selected').val().toUpperCase(); var gmapsMapType = google.maps.MapTypeId.+maptype; map.setMapTypeId(gmapsMapType); Help is appreciated.

  • Alternatives to static variables in Android

    - by Mocha
    I am using static Arrays and HashMaps to store some values in my AppWidgetProvider class. But they are becoming null when the process dies, so the widget does not work anymore. Are there any alternatives to using static members to store data for an AppWidgetProvider in Android?

  • Artisan unable to access environment variables from $_ENV

    - by hansn
    Any artisan command I enter into the command line throws this error: $ php artisan <? return array( 'DB_HOSTNAME' => 'localhost', 'DB_USERNAME' => 'root', 'DB_NAME' => 'pc_booking', 'DB_PASSWORD' => 'secret', ); PHP Warning: Invalid argument supplied for foreach() in /home/martin/code/www/pc_backend/vendor/laravel/framework/src/Illuminate/Config/EnvironmentVariables.php on line 35 {"error":{"type":"ErrorException","message":"Undefined index: DB_HOSTNAME","file":"\/home\/martin\/code\/www\/pc_backend\/app\/config\/database.php","line":57}} This is only on my local development system, where I recently installed apache and php. On my production system on a shared host artisan commands work just fine. The prod system has it's own .env.php, but other than that the code should be identical. Relevant files: .env.local.php <? return array( 'DB_HOSTNAME' => 'localhost', 'DB_USERNAME' => 'root', 'DB_NAME' => 'pc_booking', 'DB_PASSWORD' => 'secret', ); app/config/database.php <?php return array( 'fetch' => PDO::FETCH_CLASS, 'default' => 'mysql', 'connections' => array( 'mysql' => array( 'driver' => 'mysql', 'host' => $_ENV['DB_HOSTNAME'], 'database' => $_ENV['DB_NAME'], 'username' => $_ENV['DB_USERNAME'], 'password' => $_ENV['DB_PASSWORD'], 'charset' => 'utf8', 'collation' => 'utf8_unicode_ci', 'prefix' => '', ), ), 'migrations' => 'migrations', ), ); The $_ENV array is populated as expected on the website - the problem appears to be with artisan only.

  • c++, object life-time of anonymous (unnamed) variables

    - by Joe Steeve
    In the following code, the object constructed in the last line of 'main()', seems to be destroyed before the end of the expression. The destructor is called before the '<<' is executed. Is this how it is supposed to be? #include <string> #include <sstream> #include <iostream> using std::string; using std::ostringstream; using std::cout; class A : public ostringstream { public: A () {} virtual ~A () { string s; s = str(); cout << "from A: " << s << std::endl; } }; int main () { string s = "Hello"; A os; os << s; cout << os.str() << std::endl; A() << "checking this"; } This is the output: Hello from A: 0x80495f7 from A: Hello This is the gdb log: (gdb) b os.cxx : 18 Breakpoint 1 at 0x80492b1: file os.cxx, line 18.

  • Randomly Losing Session Variables Only In Google Chrome & URL Rewriting

    - by Toby
    Using Google Chrome, I'm seemingly losing/corrupting session data when navigating between pages (PHP 5.0.4, Apache 2.0.54). The website works perfectly fine in IE7/8, Firefox, Safari & Opera. The issue is only with Google Chrome. I narrowed down the problem. I'm using search friendly URL's, and hiding my front controller (index.php) via a .htaccess file. So the URL looks like: www.domain.com/blah/blah/ Here's the .htaccess file contents: Options +FollowSymlinks RewriteEngine on #allow cool urls RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*) index.php [L] #allow to have Url without index.php If I remove the .htaccess file, and expose the front controller in the URL: www.domain.com/index.php/blah/blah/, Chrome works perfectly fine. Any thoughts ideas? I'm thinking it's some kind of problem with how Chrome identifies what cookie to use and send to the server? This happens in Chrome 4 & 5. Thanks!

  • jQuery each loop - using variables

    - by Sam
    I have a list of products. Each product has a title and a review link. Currently the titles link directly to the individual product page, and the review links go elsewhere. I'd like to use a jquery each loop to cycle through each li, take the href from the title (the first link), and apply it to the review link (the second link), so they both point to the product page. Simplified code would be as follows: <ul> <li><a href="product1.html">Product 1</a><a href="review1.html">Review 1</a></li> <li><a href="product2.html">Product 2</a><a href="review2.html">Review 2</a></li> <li><a href="product3.html">Product 3</a><a href="review3.html">Review 3</a></li> </ul> I thought it would be something like the following: $("li").each(function(){ var link = $("a:eq(0)").attr('href'); $("a:eq(1)").attr("href", link); }); But it always uses the same variable "link". Can someone help me out?

  • Javascript storing properties and functions in variables

    - by richard
    Hello, I'm having trouble with my programming style and I hope to get some feedback here. I recently bought Javascript: The Good Parts and while I find this a big help, I'm still having trouble designing this application. Especially when it comes to writing function and methods. Example: I have a function that let's the user switches games in my app. This function updates game-specific information in the current view. var games = { active: Titanium.App.Properties.getString('active_game'), gameswitcher_positions: { 'Game 1': 0, 'Game 2': 1, 'Game 3': 2, 'Game 4': 3, 'Game 5': 4 }, change: function(game) { if (active_game !== game) { gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage = gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage.replace('_selected', ''); gameswitcher.children[this.gameswitcher_positions[game]].backgroundImage = gameswitcher.children[this.gameswitcher_positions[game]].backgroundImage.replace('.png', '_selected.png'); events.update(game); this.active = game; } }, init: function() { gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage = gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage.replace('.png', '_selected.png'); events.update(this.active); } }; gameswitcher is a container view which contains buttons to switch games. I am not satisfied with this approach but I cannot think of a better one. Should I place the gameswitcher_positions outside of the variable in a seperate variable instead of as a property? And what about the active game? Please give me feedback, what am I doing wrong?

  • Public static variables and Android activity life cycle management

    - by jsstp24n5
    According to the documentation the Android OS can kill the activity at the rear of the backstack. So, say for example I have an app and open the Main Activity (let's call it Activity A). In this public activity class I declare and initialize a public static variable (let's call it "foo"). In Activity A's onCreate() method I then change the value of "foo." From Activity A the user starts another activity within my app called Activity B. Variable "foo" is used in Activity B. Activity B is then paused after the user navigates to some other activities in other apps. Eventually, after a memory shortage occurs, Activity A then Activity B can be killed. After the user navigates back to my app it restarts (actually "recreates") activity B. What happens: 1) Will variable "foo" at this point have the value that was set to it when Activity A's onCreate() method ran? 2) Variable "foo" does not exist? 3) Variable "foo" exists and but is now the initialized value and not the value set in Activity A's onCreate() method?

  • How to access parent window variables from object

    - by Pickle
    I've got an XHTML 1.1 Strict document that is loading another XHTML 1.1 document in an <object> element (as <iframe> isn't part of the XHTML 1.1 spec). I'm having trouble in IE8 (don't care about 6 or 7) with accessing a javascript variable, Lightbox, in the parent window, from the document loaded in the <object>. In Firefox and everywhere I've seen online, I can just use window.parent.Lightbox. In IE8 however, I get it being undefined. window.parent does give me an object but it doesn't have my Lightbox variable. I've also tried window.Lightbox, window.top.Lightbox, and window.top.document.Lightbox, but all return undefined. I should mention I'm using Javascript to set the data property of the <object> - but I don't see how that could affect anything relevant. What Javascript Fu do I need to do to be able to access my Lightbox variable?

  • cmd.exe Command Line Parsing of Environment Variables

    - by Artefacto
    I can't figure how to have cmd.exe not interpret something like %PATH% as an environment variable. Given this program: #include<stdio.h> #include<windows.h> int main(int argc, char *argv[]) { int i; printf("cmd line: %s\n", GetCommandLine()); for (i = 0; i < argc; i++) { printf("%d: %s\n", i, argv[i]); } return 0; } I have these different outputs according to the position of the arguments: >args "k\" o" "^%PATH^%" cmd line: args "k\" o" "%PATH%" 0: args 1: k" o 2: %PATH% >args "^%PATH^%" "k\" o" cmd line: args "^%PATH^%" "k\" o" 0: args 1: ^%PATH^% 2: k" o I guess it's because cmd.exe doesn't recognize the escaped \" and sees the escaped double quote as closing the first, leaving in the first case %PATH% unquoted. I say this, because if I don't quote the argument, it always works: >args ^%PATH^% "k\" o" cmd line: args %PATH% "k\" o" 0: args 1: %PATH% 2: k" o but then I can have no spaces...

  • backslashes in url variables

    - by namtax
    Hi there I have set up my coldfusion application to have dynamic urls on the page, such as www.musicExplained/index.cfm/artist/:VariableName However my variable names will sometimes contain backslashes, such as www.musicExplained/index.cfm/artist/GZA/Genius This is causing a problem, because my application presumes that the slash in the variable name represents a different section of the website, the artists albums. So the URL will fail. I am wondering if there is anyway to prevent this from happening? Do I need to use a function that replaces slashes in the variable names with another character? Thanks

  • Using Array Variables For FILE_GET_CONTENTS

    - by Whoshooter
    I have a script all done now and everything has been debugged and it works, except for the last hurdle. This script grabs pertinent information on bank web sites, takes that data and uses it to populate a template and then it's all posted to Wordpress - BUT I get an error because the file_get_contents function fails taking each url from the Array.

  • Callback function and function pointer trouble in C++ for a BST

    - by Brendon C.
    I have to create a binary search tree which is templated and can deal with any data types, including abstract data types like objects. Since it is unknown what types of data an object might have and which data is going to be compared, the client side must create a comparison function and also a print function (because also not sure which data has to be printed). I have edited some C code which I was directed to and tried to template, but I cannot figure out how to configure the client display function. I suspect variable 'tree_node' of class BinarySearchTree has to be passed in, but I am not sure how to do this. For this program I'm creating an integer binary search tree and reading data from a file. Any help on the code or the problem would be greatly appreciated :) Main.cpp #include "BinarySearchTreeTemplated.h" #include <iostream> #include <fstream> #include <string> using namespace std; /*Comparison function*/ int cmp_fn(void *data1, void *data2) { if (*((int*)data1) > *((int*)data2)) return 1; else if (*((int*)data1) < *((int*)data2)) return -1; else return 0; } static void displayNode() //<--------NEED HELP HERE { if (node) cout << " " << *((int)node->data) } int main() { ifstream infile("rinput.txt"); BinarySearchTree<int> tree; while (true) { int tmp1; infile >> tmp1; if (infile.eof()) break; tree.insertRoot(tmp1); } return 0; } BinarySearchTree.h (a bit too big to format here) http://pastebin.com/4kSVrPhm

I cant figure out if its because its asynchronous or because the variable is out of scope.

  • Sending Variables in Post without the input tag

    - by abhishekgupta92
    I want to send only one variable via the post method. I have queried the database and have to post $row[id] variable to the page along with the form. To send the user's input we simply write like <input type="text" name="xyz"></input> and then we access it as $_POST[xyz]. This way we can send a variable that a user write. But, I want to send something that user has not written but there in my sending file as $row['id']. So, I want to send this variable as well. How can I do that? And also how will I be able to access that?

  • Looping through with double variables

So i want a hyphen to seperate the two arrays, with the first array staying the same until the second array has looped through. I am trying to get this in a dropdown with option value. How could i achieve this? I never tried doing any loops with two varaibles like that before, I literally have no idea at all! Thankyou

  • How to use Multiple Variables for a lock Scope in C#

    - by Gunner
    I have a situation where a block of code should be executed only if two locker objects are free. I was hoping there would be something like: lock(a,b) { // this scope is in critical region } However, there seems to be nothing like that. So does it mean the only way for doing this is: lock(a) { lock(b) { // this scope is in critical region } } Will this even work as expected? Although the code compiles, but I am not sure whether it would achieve what I am expecting it to.
