  • How to create a snapshot or clone of PHP, MySQL page... Inspiration needed

    - by jimbo
    Hi, We have a web application that creates a dynamic PHP page with all the MySQL stored details a user has entered via a number a forms. So far so good, but we want this information stored some how to be refereed to at a later date, as an administrator can make changes to the data, which reflects on calculations that are worked out from this saved data. When going back over this saved data we need to be able to see all the information submitted for that particular calculation, so if that data has changed we will see what is was relating to that calculation. Now we have thought about maybe a snapshot when the calculation is done, pdf of the webpage or something similar would do, but is this simple to do? I hope this makes sense...

  • How to make dll referenced by ActiveX component accessible?

    - by sherpa
    I have an ActiveX component developed in C#. I'm referencing a dll which comes with other native dlls and it is loading them on the fly expecting them to be in the same folder (probably using Assembly.GetExecutingAssembly().Location but not sure, I don't have control over them). There is also one ini file which is also expected to be in the same folder. When I run the application as Windows form app, everything is fine, of course. But the trouble comes when I run it within Internet Explorer as the base directory is at the location of iexplore.exe. Obviously neither the dlls or the ini file can be found and many temporary working files outputted by the dlls are located in Internet Explorer folder. The workaround is to copy all ddls and ini file into the ie folder but that is not something I'd be happy about. What is the proper solution to this? Can I somehow set the base path for the ActiveX component?

  • Silently binding a variable instance to a class in C++?

    - by gct
    So I've got a plugin-based system I'm writing. Users can create a child class of a Plugin class and then it will be loaded at runtime and integrated with the rest of the system. When a Plugin is run from the system, it's run in the context of a group of plugins, which I call a Session. My problem is that inside the user plugins, two streaming classes called pf_ostream and pf_istream can be used to read/write data to the system. I'd like to bind the plugin instance's session variable to pf_ostream and pf_istream somehow so that when the user instantiates those classes, it's already bound to the session for them (basically I don't want them to see the session internals) I could just do this with a macro, wrapping a call to the constructor like: #define MAKE_OSTREAM = pf_ostream_int(this->session) But I thought there might be a better way. I looked at using a nested class inside Plugin wrapping pf_ostream but it appears nested classes don't get access to the enclosing classes variables in a closure sort of way. Does anyone know of a neat way to do this?

  • How to determine bandwidth used by cron job?

    - by Lost_in_code
    I'm not a unix guy. CPanel does a good job of managing cronjobs and that is what I used to run dozens of cronjobs. All of them combined run more than 5000 times every day. Every cron makes a call to an external API. How can I check how much bandwidth are all the cron jobs eating? For my website I use awstats and that shows bandwidth usage et al. Another thing is that I dont want the admins to ban the cron jobs because they are using too much bandwidth (and CPU), more than what is allocated in my web hosting package.

  • Robocopy Invalid Parameters

    - by Drue
    I'm using the batch command robocopy to copy my website source files from my flash drive to my dad's laptop for a backup. I've ran it as an administrator and I get an invalid parameter error message. Here's what I have so far: @echo off robocopy "G:\xampp-portable\htdocs" "W:\xcopytest" /e pause>nul I want to use %cd% instead of "G:\xampp-portable" Also, my .bat file is in G:\xampp-portable. UAC is set to normal and I'm using Windows 7. [EDIT] I tried a similar code in 'W:\' under a test folder and it worked fine. I think the problem is the drive to drive. [/EDIT]

  • Aptana Open Resource Key Binding

    - by yagudaev
    The default keyboard shortcut for open resource in Eclipse is Ctrl+Shift+R. It is also the case in Aptana, but there also seems to be a conflicting key since when clicked it brings up a context menu with 2 options "Run" and "Open Resource". How to I avoid having this context menu pop up? I tried to go to the preferences and look for conflicting key-bindings but I could not find it. I am also not sure what "Run" command is actually bound (I tried searching based on the key combination, that did not seem to have worked).

  • MySQL TEXT field performance

    - by Jonathon
    I have several TEXT and/or MEDIUMTEXT fields in each of our 1000 MySQL tables. I now know that TEXT fields are written to disk rather than in memory when queried. Is that also true even if that field is not called in the query? For example, if I have a table (tbExam) with 2 fields (id int(11) and comment text) and I run SELECT id FROM tbExam, does MySQL still have to write that to disk before returning results or will it run that query in memory? I am trying to figure out if I need to reconfigure our actual db tables to switch to varchar(xxxx) or keep the text fields and reconfigure the queries.

  • Firefox running infinitely even after condition met in jquery function

    - by Kyle
    The following function is called with setTimeout(function () { get_progress(fileID,fileName)},8000); upon a form submit. The purpose of the function is to get read_file.php to read a txt file that stores the file upload status from a form (in percentage). Upon reaching 80%, my Firefox seems to run infinitely even when HEAD returns an error. Am I have too many recursions or have I used a wrong condition that's causing get_progress to run repeatedly even when filename does not exist in the folder ? function get_progress( fileID, filename) { $.ajax({ url: filename, type: 'HEAD', success: function() { $.ajax({ type: 'POST', url: 'read_file.php', data: 'filename=' +filename, success: function(html) { document.getElementById(fileID).innerHTML = html + ' <img src="images/loading.gif" />' setInterval(function() {get_progress(fileID,filename)},4000); } }); } });}

  • "IOError [Errno 13] Permisson denied" when copy a file on Windows

    - by wong2
    Hi, I wrote a program that will copy a file called a.exe to C:/Windows/, then I pack it to exe with PyInstaller, and rename the exe file to a.exe. When I run the exe file, it output IOError [Errno 13] Permisson denied: 'C:/Windows/a.exe', but the file a.exe was copied to the directory C:/Windows. Then I ran it as the Administrator, it happened again... At first, I copy the file with shututil.copy, then I wrote a function myself(open a.exe, create a.exe under C:/Windows, read a.exe 's content and write to C:/Windows/a.exe, close all), but it doesn't help...Any ideas?

  • bash—Better way to store variable between runs?

    - by shardbearer
    I've made a bash script which I run every hour with crontab, and I need to store one variable so that I can access it the next time I run it. The script changes the variable every time it runs, so I can't hardcode it in. Right now I am writing it to a txt file and then reading it back. Is there a better way to do it than this? And the way I am reading the txt file is something I found on here, I don't understand it, and it's kinda clunky. Is there not a built in command for this? Anyway, here's the applicable code, with some of the variables changed to make it easier to read. while read x; do var=$x done < var.txt # Do some stuff, change var to a new value echo $var > var.txt The variable is only a single integer, so the text file feels overkill.

  • Progress Dialog on open activity

    - by GeeXor
    hey guys, i've a problem with progress dialog on opening an activity (called activity 2 in example). The activity 2 has a lot of code to execute in this OnCreate event. final ProgressDialog myProgressDialog = ProgressDialog.show(MyApp.this,getString(R.string.lstAppWait), getString(R.string.lstAppLoading), true); new Thread() { public void run() { runOnUiThread(new Runnable() { @Override public void run() { showApps(); } }); myProgressDialog.dismiss(); } }.start(); The showApps function launch activity 2. if i execute this code on my button click event on activity 1, i see the progress, but she doesn't move and afeter i have a black screen during 2 or 3 seconds the time for android to show the activity. If i execute this code in the OnCreate of Activity2 and if i replace the showApps by the code on OnCreate, Activity1 freeze 2 seconds, i don't see the progress dialog, and freeze again 2 seconds on activity 2 before seeing the result. An idea ?

  • Can return and else statements be used interchangable in CFScript?

    - by Mel
    I would like to know your opinion on using return and else statements interchangeably in CFScript. I generally use the following syntax: if (something) { // Do something } else { // Do something else } It recently occurred to me I could do this instead: if (something) { // Do something return; } // Do something else Would those two styles yield a different end result? I like not having to wrap code in an else statement. My thinking is that if the if statement evaluates true and returns, the code below it will not run. If it does not evaluate true, then the code below it will run regardless of whether it is wrapped in an else statement or not. Does that sound write?

  • Time for creation of database on site

    - by slo2ols
    Hi. When and where would you create database to develop web site using ASP.NET MVC 2 and Entity Framework 4 (CreateDatabase method). I think about first run of web site and redirect on welcome page, when controller creates database from model. But I doubt about details: 1. Where? In HttpModule, but request of any image or css will check that database exist. In custom RouteHandler, but then anybody need to know that need to use this handler when to add route. In BaseController, but then code will look like SomeController(..., IDatabase database) : base(database). 2. When? Better create database on first run by any url or may be on deployment of site (additional tool which create ObjectContext and invoke CreateDatabase)? Thanks.

  • Terminating a long-executing thread and then starting a new one in response to user changing parameters via UI in an applet

    - by user1817170
    I have an applet which creates music using the JFugue API and plays it for the user. It allows the user to input a music phrase which the piece will be based on, or lets them choose to have a phrase generated randomly. I had been using the following method (successfully) to simply stop and start the music, which runs in a thread using the Player class from JFugue. I generate the music using my classes and user input from the applet GUI...then... private playerThread pthread; private Thread threadPlyr; private Player player; (from variables declaration) public void startMusic(Pattern p) // pattern is a JFugue object which holds the generated music { if (pthread == null) { pthread = new playerThread(); } else { pthread = null; pthread = new playerThread(); } if (threadPlyr == null) { threadPlyr = new Thread(pthread); } else { threadPlyr = null; threadPlyr = new Thread(pthread); } pthread.setPattern(p); threadPlyr.start(); } class playerThread implements Runnable // plays midi using jfugue Player { private Pattern pt; public void setPattern(Pattern p) { pt = p; } @Override public void run() { try { player.play(pt); // takes a couple mins or more to execute resetGUI(); } catch (Exception exception) { } } } And the following to stop music when user presses the stop/start button while Player.isPlaying() is true: public void stopMusic() { threadPlyr.interrupt(); threadPlyr = null; pthread = null; player.stop(); } Now I want to implement a feature which will allow the user to change parameters while the music is playing, create an updated music pattern, and then play THAT pattern. Basically, the idea is to make it simulate "real time" adjustments to the generated music for the user. Well, I have been beating my head against the wall on this for a couple of weeks. I've read all the standard java documentation, researched, read, and searched forums, and I have tried many different ideas, none of which have succeeded. The problem I've run into with all approaches I've tried is that when I start the new thread with the new, updated musical pattern, all the old threads ALSO start, and there is a cacophony of unintelligible noise instead of my desired output. From what I've gathered, the issue seems to be that all the methods I've come across require that the thread is able to periodically check the value of a "flag" variable and then shut itself down from within its "run" block in response to that variable. However, since my thread makes a call that takes several minutes minimum to execute (playing the music), and I need to terminate it WHILE it is executing this, there is really no safe way to do so. So, I'm wondering if there is something I'm missing when it comes to threads, or if perhaps I can accomplish my goal using a totally different approach. Any ideas or guidance is greatly appreciated! Thank you!

  • Annotation retention policy: what real benefit is there in declaring `SOURCE` or `CLASS`?

    - by watery
    I know there are three retention policies for Java annotations: CLASS: Annotations are to be recorded in the class file by the compiler but need not be retained by the VM at run time. RUNTIME: Annotations are to be recorded in the class file by the compiler and retained by the VM at run time, so they may be read reflectively. SOURCE: Annotations are to be discarded by the compiler. And although I understand their usage scenarios, I don't get why it is such an important thing to specify the retention policy that retention policies exist at all. I mean, why aren't all the annotations just kept at runtime? Do they generate so much bytecode / occupy so much memory that stripping those undeclared as RUNTIME does make that much difference?

  • Secure Menu Items Based on User

    - by Mike Wills
    On this winform application I am writing, I want to secure one menu item from most users. It runs a month-end and cannot be easily backed out if accidentally run. The menu option opens up a window to prompt the user for some information before processing. I don't care where exactly I do the check, but I want to be sure only certain users can run this function. A Google search (on my question title above) didn't turn up anything obvious. Can anyone point me in a direction to pick up who is signed into Windows and how to check if they are authorized?

  • Can Android Applications ( using libraries build from NDK ) be used on both x86 & ARM platform?

    - by Vibgyor
    I am going to build an Android application in which I want to use a C library. So, I am planning to use NDK along with the SDK. NDK supports ARMv5, ARmv7 and x86 instruction set. Now, if I build an Android application using ARMv5 , will it run on Android phones based on Intel ( x86 ) platform (am I missing something ?)? If not, then what is the way by which I can build an ANdroid application ( which uses some C libraries underneath ) that can run on all the Android phones irrespective of the underneath platform?

  • RSpec leaves record in test database

    - by DMiller
    Whenever I run a user test, RSpec leaves the Fabricated user in the test database after the test has completed, which is messing up my other tests. I will do a rake db:test:prepare, but when I run my tests again, the record is recreated in my database. I have no idea why this is happening. It only happens with user objects. In my spec_helper file I even have: config.use_transactional_fixtures = true Here is an example test that creates a record: it "creates a password reset token for the user" do alice = Fabricate(:user) post :create, email: alice.email expect(assigns(alice.password_reset_token)).to_not eq(nil) end Fabricator: Fabricator(:user) do email { Faker::Internet.email } password 'password' name { Faker::Name.name } end Could this have anything to do with my users model?
