• Uninstaller that can work with failed installs

  - by Nifle

  I'd like an application that can uninstall applications that does not show up in the normal add/remove applications. I have an application that failed to install properly. It installs half way and then crashes leaving short cuts, folders with exe and config files in and some stuff in the registry. Ideally I would like to be able to point the uninstaller to the install dir and tell it to remove everything that references files in that dir.

• Using Google AppEngine app as a OAuth provider

  - by Alistair

  Hi, I'm using the Google AppEngine 1.3.4 SDK which offers to allow your application to act as a OAuth service provider (http://code.google.com/appengine/docs/python/oauth/). Setting up a standard application on my localhost and using the following: Request URL /_ah/OAuthGetRequestToken Authorize URL /_ah/OAuthAuthorizeToken Access Token URL /_ah/OAuthGetAccessToken The client application just gets sent to a page requesting to grant OAuth access even though no user is logged in. Clicking 'Grant access' results in a message saying 'OAuth access granted' with no tokens or anything exchange. Can't see how this could work when it's not even prompting for a login. As this functionality is quite new I can't find much out there. I've created a OAuth provider before in Rails and know that you need a Consumer Key and Secret, something that seems to be lacking in GAE? Any ideas on how to get OAuth working in a sample GAE project are most welcome.

• VB.NET - Read lines from command line to Windows form possible?

  - by Yiu Korochko

  Hey Overflow, I have an application which serves as a user interface for a spartan/command line program. I have the program running on a separate process, and my application monitors it to see if it is responding and how mush CPU it is utilising. Now I have a list of files in my program (listbox) which are to be sent to the application, which happens fine. But I want to be able to read text from the com-line so as to determine when the first file has been processed. Com-line says one of "selecting settings", "unsupported format" and "cannot be fixed". What I want to be able to do is when it says one of these three things, remove item(0) in listbox1. Is this possible? I thought of programming an event which handles com_exe.print or something or other, if possible.

• Flex/AIR/HTML PDF scriptable viewer

  - by Lizzan

  Hi all! I've written a PowerPoint-like application in Flash, and now our client would like to view the speaker notes (a PDF file) on a separate screen while using the application. What I would need is a separate application/html page which can show the PDF and programmatically change page when the master slide changes. Is this possible? If so, is it easiest to go with a html page + javascript or a Flex/AIR app? It needs to be done without changing the PDF's, since there are 600+ files that need to be viewable.

• BackgroundWorker not working with TeamCity NUnit runner

  - by Catalin DICU

  I'm using NUnit to test View Models in a WPF 3.5 application and I'm using the BackgroundWorker class to execute asynchronous commands.The unit test are running fine with the NUnit runner or ReSharper runner but fail on TeamCity 5.1 server. How is it implemented : I'm using a ViewModel property named IsBusy and set it to false on BackgroundWorker.RunWorkerCompleted event. In my test I'm using this method to wait for the BackgroundWorker to finish : protected void WaitForBackgroundOperation(ViewModel viewModel) { int count = 0; while (viewModel.IsBusy) { RunBackgroundWorker(); if (count++ >= 100) { throw new Exception("Background operation too long"); } Thread.Sleep(100); } } private static void RunBackgroundWorker() { Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate { })); System.Windows.Forms.Application.DoEvents(); } Well, sometimes it works and sometimes it hangs the build. I suppose it's the Application.DoEvents() but I don't know why...

• Automate open dialog box

  - by Andrey M.

  Is there any way to automate a opening files with open dialog box on Mac OS? The application asks user to open files with the standard open dialog box. But I need open files automatically. The idea is to write script or a small application which will click the button in the target application to open dialog box and then somehow select files which I needed. But I don't know how can I do it. Any suggestions will be very appreciated.

• Java - JPA - When we need more than one EntityManager?

  - by Yatendra Goel

  I am learning JPA and have one question: In which situations we need more than one EntityManager in our application? The two situations that I am aware of are as follows: When our application is a multi-threaded application and more than one thread needs JPA transaction because EntityManager is not thread-safe and we need one EntityManager per thread. When any of the thread needs multiple concurrent transactions, we need more than one EntityManager in that thread because there is one-to-one relationship between EntityManager and EntityTransaction. Q1. Are there any other situations when we need more than one EntityManager? ================================================================================= Q2. Upto my understanding, there should be only one EntityManagerFactory per Persitence Unit. Am I correct? If not, then what are those situations when we need multiple EntityManagerFactory per Persistence Unit?

• lowest latency, least overhead app server?

  - by Mark Harrison

  I'm designing an application which will have a network interface for feeding out large numbers of very small metadata requests. The application code itself is very fast, basically looking up data cached in memory and sending it to the client. What's the absolute lowest latency I can get for a network application server running on a linux box? This will be an internal app running on gigE with no authentication. Any language/framework considered, with a preference for C, C++, or Python. Likewise for protocol, although HTTP would be nice.

• Why wouldn't a flex remoteobject work within a custom component?

  - by Gary

  Please enlighten this flex noob. I have a remoteobject within my main.mxml. I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint. When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence. How could this be? No spelling errors, or anything like that. mxml code: &ltmx:RemoteObject id="myService" destination="remoteService" endpoint="$(Application.application.home}/messagebroker/amf" &gt &lt/mx:RemoteObject%gt function call is just 'myService.getlist();' when I move it to a custom component, I import mx.core.Application; so the compiler doesn't yell

• Using Office 2010 web apps with ASP.NET

  - by Martin de Ruiter

  Would it be possible to use the Office 2010 web apps with an ASP.NET application? For example: - For each user of my ASP.NET application there is a folder with Word documents on my server - The ASP.NET application displays the available documents in a grid to the user - When clicking on one of the documents in the grid, the Word document is loaded in an IFrame which contains the Office 2010 web apps Word interface and editing of the document can take place - After editing, the document can be saved to the server, and the ASP.NET grid displays an updated status Would such a scenario be possible? And what do you need, e.g. Sharepoint, Office 2010 licenses?

• using MEF with NHibernate and windsor

  - by Fran

  I have an ASP.net MVC application that is using NHibernate under the covers for data access. I'm using the Windsor container to handle injecting ISession references into each controller. This works great, but now I'm looking to expand my application with a pluggable architecture so that I can have a core product and specific add-ons. I found a great article on doing this with MEF. My question is how to make the Windsor container and MEF container, life/work together so that I can achieve this. There was an article (http://codebetter.com/blogs/glenn.block/archive/2009/10/31/should-i-use-mef-with-an-ioc-container.aspx) by Glenn Block that talked about this exact issue. Then end then said that the next article would show you how to do this, but there's no part 2. Has anyone created an application like this using asp.net mvc, mef, nhibernate, castle windsor?

• Customer Passenger Error Pages

  - by Adam

  How do you replace the Passenger Application failed to load error messages. They are lovely, but I'd rather not display them when we move our application to production. It'd be better to just show them on the dev box and maintenance page on the live site. For clarification, this is the call stack page passenger displays when your rails app fails to load. I'd rather not modify the passenger template files directly. Passenger doesn't seem to be respecting: ErrorDocument 500 /500.html

• Make emacs not remove the BOM from XML files

  - by Vebjorn Ljosa

  I use Emacs to edit an XML file that is also read by another application. The other application requires that the file start with a byte-order marker (BOM). However, Emacs seems to remove the BOM every time I edit the file. Is there a way to make Emacs leave the BOM alone?

• CherryPy configuration tools.staticdir.root problem

  - by Alan Harris-Reid

  Hi there, How can I make my static-file root directories relative to my application root folder (instead of a hard-coded path)? In accordance with CP instructions (http://www.cherrypy.org/wiki/StaticContent) I have tried the following in my configuration file: tree.cpapp = cherrypy.Application(cpapp.Root()) tools.staticdir.root = cpapp.current_dir but when I run cherrpy.quickstart(rootclass, script_name='/', config=config_file) I get the following error builtins.ValueError: ("Config error in section: 'global', option: 'tree.cpapp', value: 'cherrypy.Application(cpapp.Root())'. Config values must be valid Python.", 'TypeError', ("unrepr could not resolve the name 'cpapp'",)) I know I can do configuration from within the main.py file just before quickstart is called (eg. using os.path.abspath(os.path.dirname(file))), but I prefer using the idea of a separate configuration file if possible. Any help would be appreciated (in case it is relevant, I am using CP 3.2 with Python 3.1) TIA Alan

• Windows Azure: need to know the data processing time

  - by veda

  I have stored some files in the form of blobs on azure and I have written an application that would access these blobs. When I host this application as a web role on azure, it works perfectly and I am happy with that. But now, I wanted to know “what is the query time taken to access each blob file?” I was searching for this through the Microsoft Azure Storage SLA and I found that for GetBlob request type, the maximum processing time should be within the product of 2 seconds multiplied by the number of MBs transferred in processing the request. I am still unclear. What is the actual processing time of my data query? How can I measure it? Can I be able to speed up the processing time? I can understand that the processing time depends on internet speed, location of the data center where my data is being stored, and location of data center where my application is being hosted. But still, will I be able to speed up my query?

• Objective-C to Java cross compiler

  - by mvid

  It is clear that cross compilers will not be allowed by the Apple App Store, so a developer will need to be familiar with Objective-C to create applications for the iPhone. I was wondering, is there a cross compiler that will take Objective-C application code and rebuild it into a similar Java application that can be packaged for Android? That way, a developer could still learn just one language (obj-c) but put out applications on many devices. I understand that the Java port would be less optimal than a natively coded application, but could conceivably save a developer some time.

• javax.sql.DataSource.getConnection() locks system

  - by Ryan Elkins

  I'm using the Apache Commons DBCP library for connection pooling in a desktop application. I've done this before and never had a problem but the latest application has started sometimes locking up on the call to getConnection() on my DataSource. The application just hangs after that call. I'm closing up my resources when I'm done with them. Is there any known reason why this might happen? I'm not even sure where to being troubleshooting this now that I've got it narrowed down to this method. It doesn't always hang - sometimes it happens fairly quickly, sometimes it takes a long time. Sometimes it doesn't happen at all, although lately I can get it to happen within a few minutes.

• save and restore state of a tab bar controller

  - by phunehehe

  I have an application that has a UITabBarController with two tabs, each having its own navigation controller. Now I want to store the state of the application when the user closes it, so that when the user relauches the application will show the same place as the last time before it was closed. So, in applicationWillTerminate: I have [NSKeyedArchiver archiveRootObject:tabBarController toFile:@"lastVisitedTab"]; Then, in applicationDidFinishLaunching: I have UITabBarController *last= (UITabBarController *)[NSKeyedUnarchiver unarchiveObjectWithFile:@"lastVisitedTab"]; if (last) tabBarController = [last retain]; I also have an extension to UIImage to make it compliant to NSCoding. However, this doesn't work, as the state is not preserved. The first tab gets selected all the time, and no navigation is preserved either. Can someone tell me what's wrong, or show me how to do it correctly?

• How write an ads server

  - by Nisanio

  Hi everyone I want to write an ads server (like OpenX), just for fun and learning (they aren't the same). But my idea, more than writing an entire application with web interface and so on, is to write a very tiny core that provides the basic functionality in the most efficient way, like a library that other people can use to write a complete application more fitted to their needs. The objective is to make it small, very efficient and fast. Can someone help me with a list of the minimal functionality needed for this kind of application?. An Ads Server isn't only a banner delivery, there are differents methods (for example OpenX uses a very weird javascript code that i don't understand completely) Any help or guidance is more than welcome...Thanks

• Keep Windows Mobile 6 phone alive

  - by QAH

  I am making an application for Windows Mobile 6.1 Pocket PC (Touchscreen). I know when a Pocket PC's screen turns off, it goes into a standby mode and applications are pretty much halted in the background. My application can't do that. It needs to keep going. So my question is, how can I keep the phone alive (backlight turned on) until my application is done? An example of this would be video streaming applications such as Youtube. It keeps the phone on while the video is playing.

• Simple, non-blocking way to sleep?

  - by OverTheRainbow

  Hello I googled for this and read some threads here, but I haven't found a simple way to have a VB.Net application sleep for a little while and still keep the application responsive: Imports System.Net Imports System.IO Imports System.Text Imports System.Text.RegularExpressions Imports System.Threading.Thread [...] 'How to keep screen frop freezing? While True ListBox1.Items.Clear() ListBox1.Items.Add("blah") 'Not much difference ListBox1.Refresh() 'Wait 1mn Sleep(60000) End While Is there really no simple, non-blocking solution to have a VB.Net application wait for a few seconds? Thank you.
