  • Why does the android emulator camera stop unexpectedly?

    - by user490074
    I am using Android 2.2 (API Level 8). The camera is enabled in the manifest. When I try the camera icon provided by the emulator model, it runs for a few seconds showing a gray box moving around a black and white checkerboard, then dies with the error message: Sorry! The application Camera (process com.android.camera) has stopped unexpectedly. Please try again. Trying again, of course, doesn't help. I am using the provided emulator camera to compare behavior with a camera application I am working on. Why does the android emulator camera stop unexpectedly?

  • Catch unhandled exception of invisible thread

    - by user346804
    In my C++ application i use an activeX component that runs its own thread (or several I don't know). Sometimes this components throws exceptions. I would like to catch these exceptions and do recovery instead of my entire application crashing. But since I don't have access to its source code or thread I am unsure how it would be done. The only solution I can think of is to run it in its own process. Using something like CreateProcess and then CreateRemoteThread, unsure how it could be implemented. Any suggestion on how to go about solving this?

  • Resolve HTTP 304 - not modified in AJAX call made via GWT

    - by Salvin Francis
    We are using an application made in GWT with the server as tomcat. The project runs fine normally, however there are situations where the server is restarted. At such point of time, the ajax call made by the code below returns blank text with the status code as 304 RequestBuilder requestBuilder = new RequestBuilder(RequestBuilder.POST, URL.encode(serverUrl)); //-- serverUrl is the url to which this call is posted to. requestBuilder.setHeader("Content-Type", "application/x-www-form-urlencoded"); requestBuilder.setHeader("Expires","0"); requestBuilder.sendRequest( postData, new RequestCallback() { public void onError(Request request, Throwable exception) { //Do nothing } public void onResponseReceived(Request request, Response response) { //sometimes when the server is restarted, I get response.getStatusCode() = 304 and the response.getText() as blank } } ); normally we get back some data from the server inside this response text. How do we now get the data when the response itself is blank ?

  • Cannot connect via HTTPS in Java app on MacOSX (Certificate validation issue)

    - by johnnyx
    I have a java application that connects to a webservice over https. The domain where i host the webservice has a valid Goddaddy issued SSL certificate. The application works fine on Windows but on MacOSx i receive the following exception when attempting to connect to the webservice via https. sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I've tested it on two machines running Mac OS X 10.7.2 with the latest java runtime updates. I understand this is usually a problem with self signed certificates that need to be added manually, but i have a valid Godaddy issued certificate. In webbrowsers (safari & firefox) on mac os the certificate is recognized and seems ok. I even tried adding the certificate to the key chain manually like in the gase of a self signed one but to no result.

  • Session sharing

    - by GeoXYZ
    Hello, i have a problem with Session sharing... I have a single web application hosted on a server. I created in IIS 2 different domains for the same application (thus each pointing to same physical path). The first domain is used as main interface, and the second domain is used to change settings (kind of like an admin). If the user logs in (login information is stored in session) the first domain, and then goes to the second one, he is also logged in there, which is OK. but when i try to change something in the session (like email address) from the second domain, the data is changed OK but only in the first domain; in the second one i still have the old data... also what i've noticed is that when redirecting from first domain to second domain, every postback control posts back to the first domain even though i am on the second one - this causes encryption errors with the viewstate... If anyone has any ideas, i would appreciate it... Thank you.

  • VS 2008 Open Word Document - Memory Error

    - by Lord Darkside
    I am executing the following code that worked fine in a vs2003(1.1) but seems to have decided otherwise now that I'm using vs2008(2.0/3.5): Dim wordApp As Microsoft.Office.Interop.Word.Application Dim wordDoc As Microsoft.Office.Interop.Word.Document missing = System.Reflection.Missing.Value wordApp = New Microsoft.Office.Interop.Word.Application() Dim wordfile As Object wordfile = "" ' path and file name goes here wordDoc = wordApp.Documents.Open(wordfile, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing) The error thrown when the Open is attempted is : "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Does anyone have any idea how to correct this?

  • How to have Load balanced web services sending messages with nservicebus to multiple subscribers ?

    - by Mrt
    I have load balanced web servers, that with the existing code base, handles when a user logs into the site. I would like to send a broadcast message to any applications that have subscribed saying 'hey x logged in' ? So have many web servers and many applications subscribing. How does discovery work/configuration work with nservicebus ? Should each application know about each web server and subscribe individually or is this where the distributer comes in, so web servers all send to the 1 distributer and all application subscribe to single distributer and the distributer relays the message ? I've tried to research this, but having troubles. Thanks MrT

  • Custom control packaging

    - by CSharpened
    Quick question: You are building a setup for your application. The application contains a custom control developed by you, which will be shared across multiple applications. How should you package the custom control? Package the control in a Merge Module (.msm) and add the .msm file to a Windows Installer project. Package the control into a cabinet project (.cab) and add the .cab file to a Windows Installer project. Create a separate directory for the control and then package it in a Windows Installer project along with the rest of the project files. Package the control as a Web setup project and create a link to that project from the Windows Installer project. Any ideas?

  • How to limit the number of connections to a SQL Server server from my tomcat deployed java applicati

    - by CJ
    I have an application that is deployed on tomcat on server A and sends queries to a huge variety of SQL Server databases on an server B. I am concerned that my application could overload this SQL Server database server and would like some way to preventing it making requests to connect to any database on that server if some arbitrary number of connections were already in existence and unclosed. I am looking at using connection pooling but am under the impression that this will only pool connections to a specific database on the SQL Server server, I want to control the total of these combined connections that will occur to many different databases (incidentally I can only find out the names of individual db's dynamically as they change day to day). Will connection pooling take care of this for me, are am I looking at this from the wrong perspective? I have no access to the configuration of the SQL Server server. Links to tutorials or working examples of your suggested solution are most welcome!

  • Always require a plugin to be loaded

    - by axon
    I am writing an application with RequireJS and Knockout JS. The application includes an extension to knockout that adds ko.protectedObservable to the main knockout object. I would like this to always be available on the require'd knockout object, and not only when I specify it in the dependencies. I could concat the files together, but that seems that it should be unnecessary. Additionally, I can put knockout-protectedObservable as a dependency for knockout in the requirejs shim configuration, but that just leads to a circular dependency and it all fails to load. Edit: I've solved me issue, but seems hacky, is there a better way? -- Main.html <script type="text/javascript" src="require.js"></script> <script type="text/javascript"> require(['knockout'], function(ko) { require(['knockout-protectedObservable']); }); </script> -- knockout-protectedObservable.js define(['knockout'], function(ko) { ko.protectedObservable = { ... }; });

  • One regular expression to match parts in various positions

    - by richsage
    Hi all, I'm trying to parse a DSN (from a Symfony application) using regular expressions, in order to link with a secondary application, but using the same database. The DSN I currently have is: mysql:dbname=my_db_name;host=localhost with a regex of: /^(\w+):(dbname=(\w+))?;?(host=(\w+))?/ (using preg_match()). This matches OK, but fails in my test environment because the DSN elements are switched around, thus: mysql:host=localhost;dbname=my_testdb_name I could just switch them round, yes :-) but I'm sure that extraction of the host and dbname parts from both DSNs is possible with a single regular expression, and I'd like to be able to enhance my knowledge at the same time ;-) Is there a way I can do this?

  • Rails: getting logic to run at end of request, regardless of filter chain aborts?

    - by JSW
    Is there a reliable mechanism discussed in rails documentation for calling a function at the end of the request, regardless of filter chain aborts? It's not after filters, because after filters don't get called if any prior filter redirected or rendered. For context, I'm trying to put some structured profiling/reporting information into the app log at the end of every request. This information is collected throughought the request lifetime via instance variables wrapped in custom controller accessors, and dumped at the end in a JSON blob for use by a post-processing script. My end goal is to generate reports about my application's logical query distribution (things that depend on controller logic, not just request URIs and parameters), performance profile (time spent in specific DB queries or blocked on webservices), failure rates (including invalid incoming requests that get rejected by before_filter validation rules), and a slew of other things that cannot really be parsed from the basic information in the application and apache logs. At a higher level, is there a different "rails way" that solves my app profiling goal?

  • Can a proxy server cache SSL GETs? If not, would response body encryption suffice?

    - by Damian Hickey
    Can a (||any) proxy server cache content that is requested by a client over https? As the proxy server can't see the querystring, or the http headers, I reckon they can't. I'm considering a desktop application, run by a number of people behind their companies proxy. This application may access services across the internet and I'd like to take advantage of the in-built internet caching infrastructure for 'reads'. If the caching proxy servers can't cache SSL delivered content, would simply encrypting the content of a response be a viable option? I am considering all GET requests that we wish to be cachable be requested over http with the body encrypted using asymmetric encryption, where each client has the decryption key. Anytime we wish to perform a GET that is not cachable, or a POST operation, it will be performed over SSL.

    I just built a simple hello world windows azure service containing just one web role, I used visual studio 2008 and Windows azure tools for VS 1.2 I am pretty new to this and I have been trying to deploy an application all afternoon now. I'm in australia and deploying in the region Asia anywhere. I have pretty much followed the info provided on MSDN and it says uploaded 95% then after about ten minutes the deployment disappears. I have tried using the old windows azure developer portal and 30minutes later I can not access the service and it's status is either busy or stopped. I have the introductory offer for an extra small compute instance on the subscription I am deploying to. Can anyone with experience with windows azure elaborate on the subject of deploying apps and the status on my application, I am very keen to get into the platform and this issue has just about spoiled my weekend.

  • Audio input via HTML5?

    - by tibbon
    We have a VoIP application imVOX, and we are looking at various ways of expanding our reach. Part of that is writing an HTML5 application, but it requires the use of audio input from the browser (and also push to talk buttons from the browser, even if another app is focused). On the audio side, with HTML5 is there any way of taking audio input from the browser to compress and send to our servers? I know with Flash such is possible, but we're trying to avoid flash for mobile compatibility and generally looking toward the future.

    - by dubbeat
    Hi, I've got 2 files, my Application and a custom component. In my component I have a httpservice and a string named _requestUrl that is bindable. The httpservice uses this. <mx:HTTPService id="srv" url="{_requestUrl}" result="parseHttpResult(event)" resultFormat="xml" method="GET" useProxy="false"> </mx:HTTPService> In my application file I make an instance of my component in the onCreationComplete function. In this function if I say mycomponent._urlRequest ="http://mysite.com" the httpservice throws a null url error but if I say mycomponent.srv.url="http://mysite.com" it works fine. Why is this?

  • Properties.Settings.Default.Default.Save() does not work

    - by Akshay
    I have created code in WPF to let the window remember its last location like this: private void Window_Loaded(object sender, RoutedEventArgs e) { try { Rect storedLoc = Properties.Settings.Default.WindowSavedLocation; this.Top = storedLoc.Top; this.Left = storedLoc.Left; } catch { MessageBox.Show("No settings stored !"); } } private void Window_Closed(object sender, EventArgs e) { Properties.Settings.Default.WindowSavedLocation = RestoreBounds; Properties.Settings.Default.Save(); } When I build the application I can see that the app.exe.config file has the setting WindowSavedLocation but it just does not save and throws no exception. Everytime I run the application, it says "No settings stored !". It's scope is user.
