• AudioRecord doesn't work for Motorola Milestone

  - by hcpl

  I'm having this problem only on Motorola Milestone. Code: // init recorder recordInstance = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, 8000); recordInstance.startRecording(); //more code here recordInstance.stop(); The errorinformation I have (can't find more for the moment since I don't have a milestone myself for debugging): Uncaught handler: thread main exiting due to uncaught exception java.lang.IllegalStateException: stop() called on an uninitialized AudioRecord. at android.media.AudioRecord.stop(AudioRecord.java:51 6) Apparantly I'm not the only one with this problem. Some very similar threads I found (without solution): http://groups.google.com/group/android-developers/browse_thread/thread/6dd24aeb484b2e40 http://androidcommunity.com/forums/f2/problem-using-audiorecord-in-motorola-milestone-30935/ http://community.developer.motorola.com/t5/Android-App-Development-for/Problem-using-AudioRecord-on-Milestone-device/m-p/3889 http://www.fring.com/forums/showthread.php?t=16194

• Are google chrome extension "content" scripts sandboxed?

  - by jabapyth

  I was under the impression that the content_scripts were executed right on the page, but it now seems as though there's some sandboxing going on. I'm working on an extension to log all XHR traffic of a site (for debugging and other development purposes), and in the console, the following sniff code works: var o = window.XMLHttpRequest.prototype.open; window.XMLHttpRequest.prototype.open = function(){ console.log(arguments, 'open'); return o.apply(this, arguments); }; console.log('myopen'); console.log(window, window.XMLHttpRequest, window.XMLHttpRequest.prototype, o, window.XMLHttpRequest.prototype.open); This logs a message everytime an XHR is sent. When I put this in an extension, however, the real prototype doesn't get modified. Apparently the window.XMLHttpRequest.prototype that my script is seeing differs from that of the actual page. Is there some way around this? Also, is this sandboxing behavior documented anywhere? I looked around, but couldn't find anything.

• What database is a good progression from MS Access for Coldfusion?

  - by Saul

  All my (home) CF learning has so far been done using Access as a database, and as far as the DB goes I "get it". There's no database server, and no need to log on to the database or anything, and setting up table relationships is easy and visual. Oh and its essentially free to deploy. However, I'm now working on an application that's likely to be used across several businesses and probably up to 50 concurrent users. I've heard that Access really isn't up to multi user use or production use on an app. What would you recommend as more suitable, preferably easy to grasp, with minimal tweeking needed for my SQL (I used a tool to convert to MySQL and it certainly handles concatenation differently, I dont want to have to do too much debugging), visual interface available, scalable, backupable, and whatever else I need that I don't yet know I need!

• Web Service appears as website instead of developer web server

  - by stocherilac

  I recently reimaged my PC and regrabbed one of our projects from Source Safe. In our solution we have a web service that normally runs on a server, however we can build the webservice on our localhost for debugging as well. However, now whenever I grab the project from source safe it is building the webservice as a website instead of a developer web server. This is causing a variety of issue, specifically I am no longer able to specify which port I would like that webservice to use. As a result I cannot connect to our database through my local webservice. How can I change the project in my solution that controls the webservice from a website to a developer web server? MS Visual Studio 2005. MS Visual Source Safe 2005. MS SQL Server 2000. VB .NET project

• What can cause a persistent "Reload the page to get source for" error in firebug?

  - by ripper234

  I'm trying to debug the javascript of a specific page, and I keep seeing Reload the page to get source for page.htm in Firebug. On Chrome, I'm mostly able to debug the js, but sometimes I also get a blank page. What can cause such issues? I believe I always see a blank page in Chrome if I reload while the JS console is open. If I open a new Chrome tab, load the page, and then open the JS console, everything is ok. The page I'm debugging is on a localhost server (Play Framework server), although I have seen this on other pages occasionally. This only happens with inline javascript ... js that is linked from the page is displayed fine.

• directx audio video error message in debugmode

  - by clamp

  I have a c#/winforms application that uses directx to play some video and audio. whenever i start my application in debugmode i get this annoying message. i can click "continue" and everything seems to work fine. but i still want to get rid of this message. it does not show up in releasemode. Managed Debugging Assistant 'LoaderLock' has detected a problem in 'C:\pathtoexe.exe'. Additional Information: DLL 'C:\WINDOWS\assembly\GAC\Microsoft.DirectX.AudioVideoPlayback\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.AudioVideoPlayback.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

• Flex Builder 3 executing old source codes

  - by Gorro

  I'm facing this problem again and again, but can't find any solution (except mine, which is not as a good one I guess). Don't know why, sometimes Flex Builder executes old source codes after making changes. While debugging I see how it steps through a source (e.g. changing local variables) which does not exist (even if I delete all that block or function). My way to solve that is to delete the project (backing up the source codes of course) and create a new one, add the backed up sources to the project and rebuild. It starts to work as it should work, but this way is not as comfortable, especially if sources are on a remote machine and you need to configure .net back-end. Anyone knows how to solve?

• Is there a web site where I can paste a SQL Insert statement and have it break it out by column?

  - by Scott Whitlock

  I've been working on an application that has no discernable data access layer, so all the SQL statements are just built up as strings and executed. I'm constantly confronted by very long INSERT statements where I'm trying to figure out what value in the VALUES list matches up with what column in the column name list. I was about to create a little helper application where I could paste in an INSERT statement and have it show me a list of values matched up with the column names, just for debugging, and I thought, "someone else has probably done this already." Does anyone know of a web site where I can just paste in an INSERT statement and have it show me a two column table with column names in the first column and values in the second column?

• How do I ignore the UTF-8 Byte Order Marker in String comparisons?

  - by Skrud

  I'm having a problem comparing strings in a Unit Test in C# 4.0 using Visual Studio 2010. This same test case works properly in Visual Studio 2008 (with C# 3.5). Here's the relevant code snippet: byte[] rawData = GetData(); string data = Encoding.UTF8.GetString(rawData); Assert.AreEqual("Constant", data, false, CultureInfo.InvariantCulture); While debugging this test, the data string appears to the naked eye to contain exactly the same string as the literal. When I called data.ToCharArray(), I noticed that the first byte of the string data is the value 65279 which is the UTF-8 Byte Order Marker. What I don't understand is why Encoding.UTF8.GetString() keeps this byte around. How do I get Encoding.UTF8.GetString() to not put the Byte Order Marker in the resulting string?

• When to release the UIImage ?

  - by ragnarius

  I use the following code to draw a subimage UIImage* subIm = getSubImage( large, rect ); [subIm drawInRect:self.bounds]; where getSubImage is defined as follows UIImage* getSubImage(UIImage* uim, CGRect rc){ CGImageRef imref = CGImageCreateWithImageInRect(uim.CGImage, rc); UIImage* sub = [UIImage imageWithCGImage:imref]; CGImageRelease(imref); NSLog(@"subimage retainCount=%d", [sub retainCount]); // is 1 return sub; }//getSubImage Is the code correct? Is it safe to "CGImageRelease" imref? Has sub "CGImageRetained" imref? Should I release subIm (I get an error if I do)? Is subIm contained in the autorelease-pool, and , if so, how do I know this? In general, can one check if an object is contained in the autorelease pool (for debugging purpose)?

• What is possible causes of Jasper Exception

  - by CitadelCSCadet

  I have a JSP that takes an Arraylist from the session object and removes the items from it. It seemed to be working fine and then out of nowhere when I navigate to that page, the page is blank. I checked the tomcat log files and in catalina.out I am receiving a Jasper Exception an it is showing it as being on a line with the following for(int i; i < agentItems.size(); i++) agentItems is the name of the ArrayList I am using. I have been debugging it and cant seem to figure out what the problem might be. I have read that a JasperException is sometiems thrown as a JSP's NullPointerException. Is this true or am I just completely overlooking the problem? I have the web application running on a local machine and a intermediate server for development in which both of them have had no trouble. Why could it be that only on this server it is giving me problems?

• Multiple Post Requests Occuring in Quick Succession

  - by Samuel

  This is a bit of an open ended question but we have a problem with a web application that on the final step of completing an order, multiple post requests are being made, sometimes up to 10 and all within a couple of seconds to the page. Theirs nothing unusual about the page, the user fills out a form which is then validated using the jQuery form validation plugin. We've seen this behavior exhibited over a couple of different browser types, notably IE6 but also IE8. We've also managed to trigger the bug ourselves but nothing out of the ordinary seems to occur on the browsers end, everything progresses as normal. Apache logs show that multiple post requests where made at the same time and the Rails logs show that multiple posts requests were also received by the application, leading me to think it's a problem with the browser. I've exhausted all avenues that I can think of for debugging so I'm throwing this out there to see if anyone has some ideas of what we could try or look for next.

• Why is there so much poorly indented code out there?

  - by dsimcha

  The more I browse the code to open source projects in languages that aren't Python, the more I realize that it seems a lot of programmers don't believe in proper indentation. (I won't mention any projects specifically to avoid having anyone take this question too personally.) Usually code is indented, but in a way just different enough from the standard style that it drives me crazy, especially in old/crufty code. I've noticed that when I write in C-like languages, I tend to indent correctly as religiously as when I'm writing in Python, with the exception of debugging code that I actually want to stick out like a sore thumb. Given how easy it is with a modern IDE to fix incorrect indentation, what are some rationales for not religiously keeping indentation in sync with braces?

• ASP.Net Checkbox Doesn't Allow Setting Visible to True

  - by Shawn Steward

  I'm working on an old web application in Visual Studio .Net 2003 (yeeich) and I'm having an issue with a Checkbox that will not set the Visibility to True. It's declared as such: Protected WithEvents chkTraining As System.Web.UI.WebControls.CheckBox and <asp:CheckBox id="chkTraining" runat="server" Visible="False"></asp:CheckBox> When I am debugging through the line that has: chkTraining.Visible = True it goes past it fine, but as I check this value on the very next line, chkTraining.Visible = False. What could possibly be going on here? There's no events firing off or anything else going on... this really is throwing me for a loop. Thanks for your help.

• Resharper 5 - enable/disable on the fly

  - by Cristi Diaconescu

  I want to disable ReSharper 5 when debugging - it slows things down more than I'm willing to take. Is there an automatic way to do this? The next best thing would be a toolbar button to manually enable/disable it. On the Tools - Options - ReSharper page there's a comment that the VS command Resharper_ToggleSuspended would do just this. The problem is, I can't find the command when I right-click a toolbar - Customize... - 'Commands' tab - Choose 'Resharper' category. Am I missing something?

• Is it possible to run javascript with other target?

  - by Kristoffer Nolgren

  I have a facebook app that I authenticate using a general-purpose authentification. Like this: // Fixar oAuth jso_configure({ "facebook": { client_id: "393963983989013", redirect_uri: "http://resihop.herokuapp.com/", authorization: "https://www.facebook.com/dialog/oauth", presenttoken: "qs" } }); // Make sure that you have jso_ensureTokens({ "facebook": [""] }); // This dumps all cached tokens to console, for easyer debugging. //jso_dump(); jso_ensureTokens({ "facebook": [""] }); It's tirggered on document.ready. Because it's a facebook app I can't run the authentification in the iFrame. Facebook denies this using X-Frame-Options. The solution, if you authenticate with a link is to use target="_top". How do i Achieve the same effect in javascript? Maybe I need to edit one of the funcitons (though ideally not, as they are part of a library) in that case please point me in the right direction.

• Useful design patterns when dealing with spring 3 controllers

  - by Mat Banik

  Recently I was overlooking my controllers and they are bit of mess. I'd like to organize they way I set returning views Do more elegant mesageSource massaging back to the users and account for i18n Security checking, what user can access an what they can't Consistent way of calling the service layer And somehow bring consistency to the debugging lines. Do better job with error handling and serving it to the user. I'm already on mission to do security logging with AOP :) I'm just looking for patterns I could implement to help me to do all of the above. Or just some general advice in case no patterns apply, or advice on something I didn't mention but is common practice.

• Combine and compress script files in asp.net mvc

  - by victor_foster

  I am working in Visual Studio 2008, IIS7 and using asp.net MVC. I would like to know the best way to combine all of my Javascript files into one file to reduce the number of HTTP requests to the server. I have seen many articles on this subject but I'm not sure which one I should look at first (many of them are over a year old). Here are the things I would like to do: Combine my Javascript and css files Safely compress my Javascript files when I publish, but keep them uncompressed while I am debugging Cache my Css and Javascript files but allow them to refreshed with a hard refresh when they are updated without having to rename them.

• JAXWS serves only 100 requests, how to configure JAXWS to change it to unlimited?

  - by cbz

  Hello, I'm using JAXWS for generating webservices and serving using EndPoint.publish() as well as deploying war file, but as soon as it has served 100 requests it wouldn't return 101st response. How to configure JAXWS to change this count to unlimited? EDIT: solution found, first of all it was not related to JAXWS and I'm sorry for posting it here, in my first impression I thought problem is with JAXWS but after deep exploring and debugging I found problem with my persistence layer (Hibernate) where max number of sessions allowed are 100 by default. Sorry again for making you guys to think which actually does not make sense.

• What's the best way to write a maintainable web scraping app?

  - by Benj

  I wrote a perl script a while ago which logged into my online banking and emailed me my balance and a mini-statement every day. I found it very useful for keeping track of my finances. The only problem is that I wrote it just using perl and curl and it was quite complicated and hard to maintain. After a few instances of my bank changing their webpage I got fed up of debugging it to keep it up to date. So what's the best way of writing such a program in such a way that it's easy to maintain? I'd like to write a nice well engineered version in either Perl or Java which will be easy to update when the bank inevitably fiddle with their web site.

• Same-directory includes failing on a Fedora server with PHP.

  - by JimmySawczuk

  I have a couple files that look like this: index.php: <?php include('includes/header.php'); ... includes/header.php: <?php include('config.php'); ... The error I get is Warning: require(config.php) [function.require]: failed to open stream: No such file or directory in [dir]/includes/header.php on line 2 Fatal error: require() [function.require]: Failed opening required 'config.php' (include_path='.:/usr/share/pear:/usr/share/php') in [dir]/includes/header.php on line 2 I did some further debugging: when I add the call system('pwd'); to includes/header.php, it shows [dir], where it should say [dir]/includes. Adding the 'includes/' to the include path works, but isn't desirable because that would fail on the production server. The above code works on a production server, and worked fine on my development Fedora server, until I tried to change my development environment so that the Fedora server's document root is a mounted CIFS share. Any ideas? Thanks.

• Internet explore is unresponsive while loading a large page

  - by kdhamane

  We have a html page being rendered in the browser (IE) that causes the browser to hang. The page is generated through server side script (ASP.NET and viewstate is disabled). The page while loading takes a long time (its not a b\w issue since we can reproduce it on local machine) and sometimes results in script unresponsive error. On debugging the issue we found that the html size on the client side is 4.73 MB. There's also a lot of DOM traversal (using JQuery) after document is ready (jquery-document.ready). After loading as well, the page simply hangs on any user interaction (scroll, mouseover) etc. A CPU usage spike (25-50% usage) is seen during loading and on any user interaction

• How to make one ASP.NET MVC site "derive" from another.

  - by Rob Levine

  My question is similar to "ASP.NET 2 projects to share same files", but with an ASP.NET MVC slant. Basically, we have two sites, one being based mostly on the other (roughly 90% views, controllers, images, in the second are identical to the first). However, in some cases, the views may be different, or a controller in the second site may be different to the first. Are there any simple ways of achieving this in ASP.NET MVC? So far, we've looked at using linked files to have two totally seperate projects where the second project shares the files it needs from the first. One problem with this approach is that most pages in the second project don't literally exist in the virtual directory, it makes debugging a pain - you have to publish in order to generate the files so you can debug. Does anyone have any better approaches, or ways this approach can be simplified?

• Des decryption returns empty

After debugging in Des.php, i found that function _unpad($text) is returning false. The input $text is also still encoded. What could be the reason? Whenever decrypt function calls for _unpad($text) function, i am getting empty as results. Des.php resource: here

• Why doesn't my binding update whenever EditingElementStyle AND ElementStyle are set to a custom styl

  - by Pakman

  In my Visual Studio 2010 WPF application, I have the following (simplified) style: <Style x:Key="MyStyle" TargetType="{x:Type CheckBox}"> <Setter Property="Background" Value="Blue" /> </Style> If I use it as the ElementStyle AND EditingElementStyle in my DataGridCheckBoxColumn: <DataGridCheckBoxColumn Binding="{Binding IsEnabled}" ElementStyle="{StaticResource MyStyle}" EditingElementStyle="{StaticResource MyStyle}" /> Then my binding, IsEnabled, does not toggle when I check/uncheck a row's checkbox. If I remove either ElementStyle, EditingElementStyle, or both, then the binding updates no problem. Why is this?! Note: sometimes clicking around will produce an update to the binding (detected via debugging) - this is not the same as clicking another row to "commit" the value, though! Thanks!
