  • Testing perceived performance

    - by Josh Kelley
    I recently got a shiny new development workstation. The only disadvantage of this is that the desktop apps I'm developing now run very, very fast, and so I fear that parts of the code that would be annoyingly slow on end users' machines will go unnoticed during my testing. Is there a good way to slow down an application for testing? I've tried searching around, but all of the results I've been able to find seem pretty fiddly to set up (e.g., manually setting up a high-priority CPU-bound task on the same CPU core as the target app, or running a background process that rapidly interrupts and resumes the target app), and I don't know if the end result is actually a good representation of running on a slower computer (with its slower CPU, slower RAM, slower disk I/O...). I don't think that this is a job for a profiler; I'm interested in the user's perception of end-to-end performance rather than in where the time goes for particular operations.

  • Servlet request getparameter's performance

    - by Bob
    Hi, I noticed that my app is very slow sometimes, so I've done some tests. It's a very simple web app. One servlet gets some parameters than stores them. Everything's fine except one thing. It takes too long to get a parameter for the first time. It doesn't matter which parameter I try to get, but for the first time it is very slow. The strange thing is this doesn't happen always. Sometimes getting a parameter for the first time is not slow. My code looks like this request.getParameter("paramName"); request.getParameter("paramName2"); request.getParameter("paramName3"); Getting "paramName" is slow. Getting the others is very fast. By slow I mean : 200-800 millisec By very fast I mean: ~0 millisec (in the code snippet, I didn't write the performance test, but I'm using System.currentTimeMillis())

  • Update image in ASP.NET page from memory without refreshing the page.

    - by ZeeMan
    I have a command line C# server and an ASP.NET client, they both communicate via .NET Remoting. The server is sending the client still images grabbed from a webcam at say 2 frames a second. I can pass the images down to the client via a remote method call and the image ends up in this client method: public void Update(System.Drawing.Image currentFrame) { // I need to display the currentFrame on my page. } How do i display the image on the a page without saving the image to the hard disc? If it was a winForms app i could pass currentFrame to a picturebox ie. picturebox.Image = currentFrame. The above Update method gets fired at least 2 times a second. If the client was a winForms app i could simply put picturebox.Image = currentFrame and the current frame on the screen would automatically get updated. How do i achieve the same effect with ASP.NET? Will the whole page need to be reloaded etc?

  • C#: How to Make it Harder for Hacker/Cracker to Get Around or Bypass the Licensing Check?

    - by Peter Lee
    Hi all, Suppose that the user has saved the License file under the Application.StartupPath, where all users can read. And then, every time when the app starts, it will check if it can find and verify the license file. If the app can find and verify, we let the user to continue with full functinalities. If not, we prompt a MessageBox showing "Unlicencsed, continue to use with trial version, functionalities limited." My question is, if I'm a hacker/cracker, I would try to get around or bypass the licensing check instead of cracking the license file, because, if we use RSA signature, it's very difficult to crack a license file. So where should we put the license check? thanks. Merry Christmas and Happy New Year! Peter P.S.: and also, is it safe if I put a global variable IsLicensed (true / false) to limit the functionalities? Is it easy for a hacker to change IsLicensed = true?

  • Java and gstreamer-java initialisation error

    - by Mark
    I am building a small app which will play streaming audio from the internet in java (mainly internet radio stations). I have decided to use the gstreamer-java library for the sound, which uses JNA. I would like to include a check in the code, to see whether the gstreamer library has been initialised. When I have left the "Gst.init()" code out (to mimic when the library has not been initialised correctly), the application throws out the following messages: (process:21888): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.22.3/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function (process:21888): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed The app calls the gstreamer-java library. The error messages appear but the thread continues to run, hogging the CPU. Is there any way to catch the error or to add a check to prevent it from happening? An alternative would be to put the "Gst.init()" in the main class, but I am not sure if this would always guarantee the gstreamer library is initialised.

  • Providing SaaS functionality to a .NET portal with DLLs

    - by Abdullah Jibaly
    I'm not sure I'm asking the right question here, but I'm looking to provide web based functionality from one ASP.NET application to another remote 'portal-like' application. Is it possible to simply give the portal a DLL? As an example, let's say the SaaS web app has a patient-entry form that I want to be able to use from the portal application. I would like the portal app to be able to set preferences (permissions, color, style, etc), make a function call, and have that capability presented within a certain div or something. Is there any .NET technologies that provide this kind of integration?

  • Oracle XE as local recovery database and Oracle Standard as main db

    - by jbendahan
    Hi, I just wanted to know what you guys think about this. I have an app written in Visual Basic .Net as my front end and and Oracle 11g Standart database as the back-end. So I have like 20 pc's running this app locally. They're all inserting, updating, deleting data on this single database. I want to develop a solution in the case that the server database crashes or cannot stay on line. So i think of having oracle 10g XE on each pc. Thus all the data will be stored in the local db. I think about running a proccess once in a while (ex. every 15 minutes) to send/get the data to/from the main server. What do you think about this strategy?

  • Is my fragment usage correct, seems to be slow on adnroid

    - by Robertoq
    My app structure is that i have a menu with 5 menu-point om the left side, and the content on the right side.

  • "a valid provisioning file for this executable was not found" in XCode

    - by dbonneville
    I'm trying to submit my second app to the App Store. I've followed all the instructions to the best of my knowledge, but I keep getting this error when I try to build and run: "a valid provisioning file for this executable was not found" I'm letting XCode auto select the profile automatically. The one I'd like to select is greyed out. But the dropdown selection in the Build tab of the Target window says "profile doesn't match application identifier" The other thing I don't get about this is that the selection dropdown shows "com.mycompany.myapp" and then "ABCDEDFG.com.mycompany.myapp" (both of those made up) so that I see they don't match. I have the unique identifier profile installed in the Organizer and in plist file. I'm totally confused. I have followed the instructions in my book a few times and just can't get it.

  • How do I mock a custom field that is deleted so that south migrations run?

    - by muhuk
    I have removed an app that contained a couple of custom fields from my project. Now when I try to run my migrations I get ImportError, naturally. These fields were very basic customizations like below: from django.db.models.fields import IntegerField class SomeField(IntegerField): def get_internal_type(self): return "SomeField" def db_type(self, connectio=None): return 'integer' def clean(self, value): # some custom cleanup pass So, none of them contain any database level customizations. When I removed this code, I've created migrations so the subsequent migration all ran fine. But when I try to run them on a pre-deletion database I realized my mistake. I can re-create a bare-bones app and make these imports work, but Ideally I would like to know if South has a mechanism to resolve these issues? Or is there any best practises? It would be cool if I could solve these issues just by modifying my migrations and not touching the codebase. (Django 1.3, South 0.7.3)

  • Ways to call Blocks within Magento: createBlock vs Layout xml file

    - by N. B.
    Context: I'm trying to include Adminhtml blocks in the frontend of the site to replace some of the user account blocks. The first thing I'm trying to do is simply display the block on the correct page. I can replace the entire page by setting the Body of the response inside the controller, but I'm having a hard time including the block in the layout xml file and then calling it within the template. Why would I be able to create an adminhtml/sales_order_grid from Mage_Sales_OrderController using createBlock: $this->getResponse()->setBody($this->getLayout()->createBlock('adminhtml/sales_order_grid')->toHtml()); But not from a frontend layout, using a declaration <block type="adminhtml/sales_order_grid" name="orders_widget"/> within app/design/frontend/default/default/layout/sales.xml The latter produces an error without a stack trace: Fatal error: Call to a member function toHtml() on a non-object in app/code/core/Mage/Core/Model/Layout.php on line 526 Thanks for any guidance!

  • using C function in C#

    - by andrew
    i have a dll, built with mingw one of the header files contains this: extern "C" { int get_mac_address(char * mac); //the function returns a mac address in the char * mac } I use this dll in another c++ app, built using Visual C++ (2008SP1), not managed, but plain c++ (simply include the header, and call the function) But now I have to use it in a C# application The problem is that i can't figure out how exactly (i'm new in .net programming) this is what i've tried public class Hwdinfo { [DllImport("mydll.dll")] public static extern void get_mac_address(string s); } When i call the function, nothing happens (the mydll.dll file is located in the bin folder of the c# app, and it gives me no errors or warnings whatsoever)

    - by splintercell
    I have been trying for some time to serve & cache static files for my rails app using nginx. the rails app server runs mongrel_cluster and is deployed on a different host than that of nginx. following many of the available discussions I tried the following server { listen 80; server_name www.myappserver.com; ssl on; root /var/apps/myapp/current/public; location ~ ^/(images|javascripts|stylesheets)/ { root /var/apps/myapp/current; expires 10y; } location / { proxy_pass http://myapp_upstream; } } But nginx fails to find the images and to load the css and js files. Can anyone help me out here? My aim is to configure nginx in such a way that it caches the static files till expiry. Please suggest me some way to achieve this or am I missing any point here?

  • Wicket Drag and drop functionality for adding an image

    - by Marcel
    I'm making a wicket app that can manage some options for a cashdesk app. One of the options is to change the image of a selected Product. The user(manager) can choose from the already present images in the database (SQL) when this option is selected, or add a new image if the desired image is not present. Don't mention the test names and awesome images (it's still in test-fase) I prefer to see the adding of an image achieved by Drag and Drop html5 demo [dnd-upload] (From the desktop into the browser) I'm currently using Wicket-6.2.0 and wicket-dnd 0.5.0 and i can't seem to get this working! All examples I can find are from wicket 2.x or lower. It is possible to use drag and drop in Wicket-6.2, but how do I achieve this? There seems to be some DraggableBehavior in wicket? Any help is welcome! [UPDATE] Upgraded to wicket-dnd 0.6

  • How can I set a ringtone for an individual contact on Android ?

    - by PHP_Jedi
    How can I set a ringtone for an individual contact on Android ? I have found a way to set the default ringtone that applies to all contacts without an individual ringtone. But that is not what i'm trying to accomplish. I want the application to have a button "Apply ringtone to contact". When i click, I start an activityForResult displaying a list of all contacts on the phone. When a contact is selected, the contact activity closes and returns with a uri to the contact. Now all the app needs to do is to apply the selected ringtone to that spesific contact. The code for displaying and selecting contacts by an activity is already implemented and seems to work on with the app. Its only the last part left, and I have no clue about how to solve this. Any help would be usefull.

  • Debuging to simulator crashes with "exited with status 5" unless I debug

    - by tigermain
    For some reason the app I am working on has very bad PMT! Literally! Most of the time I cannot debug using the simulator without putting a breakpoint in my AppDelegate. If I don't it exists with "status 5". If I put a break point in and simple continue it works perfectly well, it also works if I run the app in the simulator when not connected to the GDB. I have tried the source on a second machine with exactly the same results. I dont have this issue building to the device?!?!?! Thanks

  • Sandbox architecture in ASP.NET?

    - by Srikanth
    Is it possible to develop a web-app in ASP.NET (framework is not a constraint), to have a sandbox architecture, and deploy widgets without disturbing the parent application? I expect both the parent application and the widget to be developed using .NET. EDIT: To elaborate, I want to have an web-app, say App1, and widgets (say wid1 and wid2). wid1 and wid2 should be like a plugin into App1, only difference is that, if I make any changes to wid1, I want to be able to deploy it without disturbing App1 or Wid2. The widgets can be something similar to a flash object, only that it needs to be developed on .net.

  • log4net - configure using multiple configuration files

    - by Gai
    Hi, I have an application consisting of a host and pluggable modules (plugins). I want to be able to configure log4net for the host and for each of the other modules. Each of them should have its own configuration file and each will log to a different file. Only the host has an App.config file. The plugins have their own config file containing the log4net config sections. Calling XmlConfigurator.Configure from one of the plugins overrides the host's app.config log4net definitions. Is there an easy way to append configurations instead of overriding them? Thanks, Gai.

  • Facebook tab application scripting

    - by zznq
    I have a web application that I am trying to port to Facebook. The app uses a few external javascript files. So initially I wanted to create an iframe Facebook application. However, it turns out that you cannot use iframes when creating a tab application(which is a requirement). By tab application I mean placing your app on the profile page next to the wall, info, photos, ect. tabs. Does any one know of a good tool to help convert my javascript to the FBJS scripting? Or better yet does anyone have a work around so that I can include my own javascript in this tabbed application? Thanks for the help.

  • Call Babel .Net Obfuscator from C# Code

    - by aron
    Hello, I have a C# WinForms app that I use to create software patches for my app. In noticed that Babel .Net includes Babel.Build.dll and Babel.Code.dll Is there a way, in my C# code, I can call Babel .Net something like: ExecuteCommand(C:\Program Files\Babel\babel.exe "C:\Patch\v6\Demo\Bin\Lib.dll" --rules "C:\Patch\babelRules.xml", 600) Here's a common script to execute a CMD prompt in C#. However if I just include the Babel.Build.dll in my winform I may be able to do it seamlessly. public static int ExecuteCommand(string Command, int Timeout) { int ExitCode; ProcessStartInfo ProcessInfo; Process Process; ProcessInfo = new ProcessStartInfo("cmd.exe", "/C " + Command); ProcessInfo.CreateNoWindow = true; ProcessInfo.UseShellExecute = false; Process = Process.Start(ProcessInfo); Process.WaitForExit(Timeout); ExitCode = Process.ExitCode; Process.Close(); return ExitCode; }
