• Halting Django's dev server via page request?

  - by Ben Blank

  I'm looking at writing a portable, light-weight Python app. As the "GUI toolkit" I'm most familiar with — by a wide margin! — is HTML/CSS/JS, I thought to use Django as a framework for the project, using its built-in "development server" (manage.py runserver). I've been banging on a proof-of-concept for a couple hours and the only real problem I've encountered so far is shutting down the server once the user has finished using the app. Ideally, I'd like there to be a link on the app's pages which shuts down the server and closes the page, but nothing I see in the Django docs suggests this is possible. Can this be done? For that matter, is this a reasonable approach for writing a small, portable GUI tool?

• Default.png images and iPad.

  - by Leg10n

  I'm about to submit my first iPad app, and I have 2 questions regarding to Default.png images. I would prefer a "splash screen" showing some artwork of my app, instead of the UI as if it was loaded, the app is a bit heavy and I've seen the users dispair when the UI is apparently loaded but it's not working. Does anyone know if apple is accepting apps with "splash screens"? I want to provide a Default-X.png for every orientation, I've read the iPad programming guide, my question is, is "Default-LandscapeLeft" a Default image rotated 90 degrees clockwise, and "Default-LandscapeRight" rotated 90 degrees counter clockwise? I'm asking this because I don't have an iPad yet to test this on. Thank you a lot in advance.

  Can someone please guide me regarding which touch framework (javascript) I should use to make a tablet app?

Or any other framework (stable) allows to use custom UI design?? Any help regarding this is appreciated .. thanks in advance

• Samsung Galaxy Tab 1 layout problems

  - by William Rae

  I'm having trouble running my app on the Galaxy tab original 7". It appears to make everything 1.5 times bigger, i.e. if I specify 40dip for a textSize in my layout, it will display as 60 dip when I run it on the tablet. I tried messing around with the display metrics and changing the density and densityDpi to 1. (When I run a toString of the display metrics in the Galaxy tab 2, they are both 1, whereas the Galaxy tab 1 has values of 1.5) The app runs very well on every phone I've tested it on, and on the Galaxy tab 2, so I can't figure out what the problem is. I even tried creating a dummy app with just a textView with a size of 40dip, and it still converted it to 60. Any ideas? Thanks.

• Why do I not see w3wp.exe processes from IIS6?

  - by AngryHacker

  I have two Windows 2003 x64 R2 IIS boxes that are ostensibly setup the same way. But for whatever reason, one of them has a W3WP.exe process for each application pool and the other one does not. What could be the reason?

• Code Igniter Update Engine

  - by tarnfeld

  Hey, I am planning to develop a pretty awesome new web app that has a one time fee including free updates of 1.X updates (X being the update). I don't want to get people to download a new version and install it manually as it can be a real pain for some people, also it's bad if there is an important bug that needs fixing and people don't update. The app will be built with Code Igniter so I was looking for some kind of integrated system that allowed me to send out updates for the web app? All suggestions are very much appreciated!

• How do I connect two apps

  - by sevaxx

  I am considering building an app in C++ that will be parsing text from the web and create some statistical results. These results I want to be fed in an external app in real time. The external app (to whose code I have no access, but can ask for a - paid - custom made addition) will then need some code to read and use these results. I am wondering what would be the best way to interconnect the two apps, in terms of speed and ease of implementation. I am considering : disk I/O (slow) a Windows service a DLL a web service a web page Perhaps I am missing a better solution ? Thank you.

• How to set the value of a wx.combobox by posting an event

  - by Adam Fraser

  The code below demonstrates the problem I am running into. I am creating a wx.ComboBox and trying to mimic it's functionality for testing purposes by posting a wxEVT_COMMAND_COMBOBOX_SELECTED event... this event strangely works fine for wx.Choice, but it doesn't do anything to the ComboBox. There doesn't appear to be a different event that I can post to the combobox, but maybe I'm missing something. I'm running this code on Python 2.5 on a Mac OSX 10.5.8 import wx app = wx.PySimpleApp() def on_btn(evt): event = wx.CommandEvent(wx.wxEVT_COMMAND_COMBOBOX_SELECTED,combobox.Id) event.SetEventObject(combobox) event.SetInt(1) event.SetString('bar') combobox.Command(event) app.ProcessPendingEvents() frame = wx.Frame(None) panel = wx.Panel(frame, -1) # This doesn't work combobox = wx.ComboBox(panel, -1, choices=['foo','bar']) # This works #combobox = wx.Choice(panel, -1, choices=['foo','bar']) combobox.SetSelection(0) btn = wx.Button(panel, -1, 'asdf') btn.Bind(wx.EVT_BUTTON, on_btn) sz = wx.BoxSizer() sz.Add(combobox) sz.Add(btn) panel.SetSizer(sz) frame.Show() app.MainLoop()

• Cocoa Launch agent registering itself after installation.

  - by Unicorn

  I have created Cocoa app which is type of launch agent. To distribute this I have created package as well which installs the app and copies the launchagnet plist file in /Libraries/LaunchAgents. Now the problem is after installation i want this app to be running in user context immediately without logoff/restart. If I register this with "launchctl" from installer, using post install script, it run in root context, as installer is running in root context. Any suggestion how the agent registers itself to launchctl and runs in user context.

• Can you make desktop shortcuts to Seamless mode Windows apps in VirtualBox on OSX?

  - by Matt

  Running the latest version of VirtualBox on OSX and hosting a Windows virtual machine. Is there a way to put shortcuts on your Mac desktop for the Windows apps that you run in seamless mode? I can't find a way to do this, so every time I want to newly launch a Windows app in seamless mode I have to access the full Windows desktop, start the app and hit HostKey+L. Really a pain for apps that you want to run in seamless mode all time.

• postgresql duplicate table names best practice

  - by veilig

  My company has a handful of apps that we deploy in the websites we build. Recently a very old app needed to be included along side a newer app and there was a conflict w/ a duplicate table name needed to be used by both apps. We are now in the process of updating an old app and there will be some DB updates. I'm curious what people consider best practice (or how do you do it) to help ensure these name collisions don't happen. I've looked at schema's but not sure if thats the right path we want to take. As the documentation prescribes, I don't want to "wire" a particular schema name into an application and if I add schema's to the user search path how would it know which table I was referring to if two schema's have the same table name. although, maybe I'm reading to much into this. Any insights or words of wisdom would be greatly appreciated!

• Should I be worried about sending Apk to client before getting paid?

  - by DanielS

  I am working on an Android app for a client. The app is practically finished, and next week I'll have a meeting with the client to present it. He'll test everything, and upon approving it he will make the payment and I'll give him the source code and publish it on Google Play. Today he called me asking for the Apk so that he can start testing it. I am worried that if we don't close the deal (for one reason or another) he might get someone to reverse engineer the Apk and get my source code/app anyway, even if obfuscated with ProGuard (I never tried, but according to this SO thread it's not that difficult to reverse engineer an Apk). My question: Am I being paranoid here and should just send the client the Apk (cause perhaps the ProGuard obfuscation is enough to make the source code useless) , or are my worries reasonable and I should stick to getting paid before delivering anything?

• Can I use meteor for this?

  - by nitelord

  I'm looking for a way to create an app which has a realtime web interface as well as an API which can be called by a node.js client while sharing most of its code. I'd like to be able to manage data, monitor and execute tasks inside of my app via browser, but also have an automation/scheduling program which connects to my web app and tells it to run various tasks and get results of each task. Unfortunately it doesn't look like I can connect to Meteor from the server, so I'm wondering if there's another approach? Is what I described even possible using Meteor? I have done some testing using socket.io and I think I may be able to do it this way, but Meteor seems like it'd be really great for the realtime user interface.

• OpenVPN Chaining

  - by noderunner

  I'm trying to set up an OpenVPN "chain", similar to what is described here. I have two separate networks, A and B. Each network has an OpenVPN server using a standard "road warrior" or "client/server" approach. A client can connect to either one for access to the hosts/services on that respective network. But server A and B are also connected to each other. The servers on each network have a "site-to-site" connection between the two. What I'm trying to accomplish, is the ability to connect to network A as a client, and then make connections with hosts on network B. I'm using tun/routing for all of the VPN connections. The "chain" looks something like this: [Client] --- [Server A] --- [Server A] --- [Server B] --- [Server B] --- [Host B] (tun0) (tun0) (tun1) (tun0) (eth0) (eth0) The whole idea is that server A should route traffic destined to network B through the "site-to-site" VPN set up on tun1 when a client from tun0 tries to connect. I did this simply by setting up two connection profiles on server A. One profile is a standard server config running on tun0, defining a virtual client network, IP address pool, pushing routes, etc. The other is a client connection to Server B running on tun1. With ip_forwarding enabled, I then simply added a "push route" to the clients advertising a route to network B. On server A, this seems to work when I look at tcpdump output. If I connect as a client, and then ping a host on network B, I can see the traffic getting passed from tun0 to tun1 on Server A: tcpdump -nSi tun1 icmp The weird thing is that I don't see Server B receiving that traffic through the tunnel. It's as if Server A is sending it through the site-to-site connection like it should, but server B is completely ignoring it. When I look for the traffic on Server B, it simply isn't there. A ping from Server A -- Host B works fine. But a ping from a client connected to Server A to host B does not. I'm wondering if Server B is ignoring the traffic because the source IP does not match the client IP pool that it hands out to clients? Does anyone know if I need to do something on Server B in order for it to see the traffic? This is a complicated problem to explain, so thanks if you stuck with me this far.

• Is there a way to bring an application's GUI to the current desktop?

  - by Davy8

  Background: Started a fair amount of work before realizing that a Windows Service cannot start an app with a GUI that displays without potential problems. The proper solution of separating the GUI of the app to be started is non-trivial, so I'm trying to think of alternative solutions. There is a GUI to manage the service that is a separate executable, but the process to be launched (actually multiple instances of it) has its own GUI that needs to be shown. It doesn't need to be made visible by the service itself, but it needs to be at least able to be made visible by another process with a visible GUI. The Windows User that is running the service and that needs to see the GUI of the launched process is the same and known at install time. Is there some way to accomplish this or is it back to the drawing board? Also both the service and the app to launch are both our code and modifiable.

• URL Routing to Default Page

  - by ewitkows

  Hi everyone, I have an asp.net 4.0 web forms app setup with url rereouting. In development, my app's URL looks perfect. I have a page called enrollnow.aspx that responds to the routing, so if I type in localhost/enrollnow/abc, my app responds as expected. Once promoted into my staging environment however, the URL is off. I have a domain, and a virtual dir created off of my domain called "enrollnow". So basically, my URL outside of development is: mydomain.com/enrollnow/enrollnow/abc - where the first enrollnow is the directory, the second enrollnow is the page name, and the abc is my route value. Is there any way I can have the "default page" respond, so the second enrollnow (which is enrollnow.asp) isnt required? Perhaps I can rename my enrollnow.aspx page to default.aspx, or I can change the mapping in my routetable? Heres my routetable, incase that helps. thanks! Routetable: RouteTable.Routes.Add("PURLRoute", New Route("EnrollNow/{PURL_ID}", New PageRouteHandler("~/EnrollNow.aspx")))

• Receiving Text From Another Application

  - by Garry

  Hi, I'm building some home automation software with Cocoa/Objective-C. The main application will have a minimal GUI and will most likely be represented by a status bar icon only. I'm using proprietary speech-to-text software (MacSpeech Dictate) that takes my voice command and converts it to plain text. I then need to send this plain text to my app for parsing. Is there a way to send a string to a Cocoa application? Could AppleScript achieve this? How would I make the NSString string in my app "available" to receive the passed string? For reasons that are beyond the scope of this question - it is not possible to dictate the command directly into my app. Many thanks in advance,

• Exclusive compute mode with OpenCL+NVidia

  - by lokli

  Hi, I have a question to exclusive compute mode with NVidia+OpenCL. I can set up exclusive compute mode (page 74 from cuda programming guide 3.0) with nvidia-smi on a nvidia-gpu . that means, only one program can compute on gpu. cuda runtime schedules than app automatically. but I have a problem with opencl-programs in this case: if one application runs on a gpu with setted exclusive compute mode and second opencl-program calls clGetDeviceInfo(..., CL_DEVICE_AVAILABLE, ...) with the same GPU is the result == CL_TRUE. After that if opencl-app tries to create a context on this device, than crashes the running app (both). How can i find out an available GPU with OpenCL? Thanks.

• Under what circumstances would a Ruby $LOAD_PATH be acquired from a parent process?

  - by Dr Nic

  In my cucumber scenarios, if I call rake db:schema:load within a target Rails app folder, I get the cucumber process's $LOAD_PATH and not the Rails app's own Gemfile/load path. I think this is very weird. The consequence is that I get the following error: no such file to load -- rails/all I can't reproduce it outside of my cucumber scenario. ruby -rubygems -e "system 'rake -T'" works normally - the 'rake -T' has the application's own Gemfile-based $LOAD_PATH; and doesn't generate the error above. Can anyone think why a child process (rake -T or rake db:schema:load or rails runner...; invoked by either system, exec, %x[...] or backtick; would start with the parent processes' $LOAD_PATH (from the cucumber scenario's Gemfile) instead of its own $LOAD_PATH (from the Rails app's Gemfile)?

• wxPython ,Change the background colour of a StyledTextCtrl

  - by user1357159

  I tried (but nothing happens) self.txt.SetBackgroundColour ((255,0,0)) As said in the title I'm trying to change the background colour StyledTextCtrl. Does anyone know a method that could be used? I've checked the API docs but I couldn't seem to find one, http://wxpython.org/docs/api/wx.stc.StyledTextCtrl-class.html (by background colour, I mean the whole writing area, of course) Does anyone know a way I could do this? EDIT: The background doesn't change in the following code import wx import wx.stc app = wx.App(redirect=True) top = wx.Frame(None, title="StyledTXTCtrl", size=(300,200)) txt=wx.stc.StyledTextCtrl(top) txt.SetBackgroundColour((255,255,0)) txt.Refresh() top.Show() app.MainLoop()

• Combining RequiresSTA and Timeout attributes on a test fails

  - by Peter Lillevold

  I have a test that opens and closes a WPF Window and thus requires the STA threading apartment. To safeguard the test against the window staying open (and thus hang the test indefinitely) I wanted to use the Timeout attribute. The problem is that applying the Timeout attribute causes the test to fail on timeout regardless of whether the test works or not. Without the attribute everything works fine. My theory is that Timeout causes the test to be executed on a new thread that does not inherit the STA apartment. Is there another way to have both STA and the timeout safeguard in NUnit? My test looks something like this: [Test, RequiresSTA, Timeout(300)] public void Construct() { var window = new WindowView(); window.Loaded += (sender, args) => window.Close(); var app = new Application(); app.Run(window); try { // ...run system under test } finally { app.Shutdown(); } }

• How can I embed the result of a rails view in another website?

  - by NotDan

  I would like to allow users to call my ruby on rails app as a service which returns a 'div' with html content in it, and embed that div into their app (which will not be a rails application). For example, assume someone has their own php website that has a header/footer template that gets rendered, and a content area of the page that they need to fill based on some html I generate in my rails app. I would like to allow them, from php, to call to my website, get the 'div' I generate, and embed that as html in their php page. What I'm trying to do is host a service on my site that returns some html content, but actually show that content as part of another site, so that the end user only sees the other site and never really knows about mine. Is this possible?

• re-open background application via notification item

  - by user356764

  I got an app with tabs and a notification bar entry, when I send it to background (click on home button) and try to re-open the application via click on the notification bar, the app restarts (last selected tab is lost). When I hold the home button if the application is in the background and select it from there or click the app's icon on the homescreen, the previous state is restored per default (the correct tab is selected) IMO the intent of the notification is wrong, but I'm not sure how to fix it. In short: How to get a background application back to foreground when I click the notification entry? thx!
