• Titanium won't run iPhone/Android Emulator

  - by BeOliveira

  I just installed Titanium SDK (1.5.1) and all the Android SDKs. Also, I already have iPhone SDK 4.2 installed. I downloaded KitchenSink and imported it into Titanium but whenever I try to run it on iPhone Emulator, I get this error: [INFO] One moment, building ...

• Using Enterprise Library DAAB in C# Console Project

  - by Kayes

  How can I prepare the configuration settings (App.config, maybe?) I need to use Enterprise Library Data Access Application Block in a C# console project? Following is what I currently trying with an App.config in the console project. When I call DatabaseFactory.CreateDatabase(), it throws an exception which says: "Configuration system failed to initialize" <configuration> <dataConfiguration> <xmlSerializerSection type="Microsoft.Practices.EnterpriseLibrary.Data.

• Understanding LinkDemand Security on a webserver

  - by robertpnl

  Hi, After deployment an ASP.Net application on a webserver, I get this error message by using code from a external assembly: "LinkDemand The type of the first permission that failed was: System.Security.PermissionSet The Zone of the assembly that failed was: MyComputer the error ". The assembly is include in the \bin folder and not in the GAC. I try to know what linkdemand exactly is and why this message will raised. But looking for more information, I don't get exactly the problem. I try also to add the PermissionSetAttribute on the class where the exception message happens: [System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.LinkDemand, Name = "FullTrust")] Then the exception will be raised on another class of the assembly. And so on.. My questions ares: - what exactly is going wrong here? Is it true that I understand that .Net cannot check the code during Jit? - Is there maybe a security policy that block this (machine.config)? - Can I set the PermissionAttribute for all classes between a assembly? Thanks.

• Sanity check: UIBarButtonItem crashes trying to perform action

  - by Giao

  One of my users is reporting a crash on his device, an iPhone 3GS. Other devices of the same type are not reporting similar behavior. He's sent me a crash log and based on reading it, I'm not sure how to proceed. I hope I'm not interpreting the crash log incorrectly but it doesn't look like my action has been called yet. This is how I'm creating and setting up the UIBarButtonItem: - (void)viewDidLoad { [super viewDidLoad]; UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addLog:)]; self.navigationItem.rightBarButtonItem = addButton; [addButton release]; } This is the my action method: - (IBAction)addLog:(id)sender { MyViewController *myController = [[MyViewController alloc] initWithNibName:@"MyNib" bundle:nil]; UINavigationController *subNavigationController = [[UINavigationController alloc] initWithRootViewController: myController]; [self presentModalViewController:subNavigationController animated:YES]; [myController release]; [subNavigationController release]; } This is the crash log: Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x00000000, 0x00000000Crashed Thread: 0 Thread 0 Crashed: 0 libSystem.B.dylib 0x0007e98c __kill + 81 libSystem.B.dylib 0x0007e97c kill + 4 2 libSystem.B.dylib 0x0007e96e raise + 10 3 libSystem.B.dylib 0x0009361a abort + 34 4 MyApp 0x000042e8 0x1000 + 13032 5 CoreFoundation 0x00058ede -[NSObject performSelector:withObject:withObject:] + 18 6 UIKit 0x0004205e -[UIApplication sendAction:to:from:forEvent:] + 78 7 UIKit 0x00094d4e -[UIBarButtonItem(Internal) _sendAction:withEvent:] + 86 8 CoreFoundation 0x00058ede -[NSObject performSelector:withObject:withObject:] + 18 9 UIKit 0x0004205e -[UIApplication sendAction:to:from:forEvent:] + 78 10 UIKit 0x00041ffe -[UIApplication sendAction:toTarget:fromSender:forEvent:] + 26 11 UIKit 0x00041fd0 -[UIControl sendAction:to:forEvent:] + 32 12 UIKit 0x00041d2a -[UIControl(Internal) _sendActionsForEvents:withEvent:] + 350 13 UIKit 0x0004263e -[UIControl touchesEnded:withEvent:] + 330 14 UIKit 0x00041656 -[UIWindow _sendTouchesForEvent:] + 318 15 UIKit 0x00041032 -[UIWindow sendEvent:] + 74

• MSWord automation:Get file contents after it was saved

  - by BlackTigerX

  I have an application that uses MSWord automation to edit some documents, after they save and close word I need to grab the modified file and put it back on the repository, there is only one scenario where I can't get it to work and that is when the user makes changes to the file, selects to close word and selects yes to save the file there are 2 events that I'm using: DocumentBeforeSave Quit on the Quit event I'm trying to load the .docx file from disk but on this particular scenario I get an IOException because the file is still in use, somehow I need to wait until after the Quit event has been processed, which is when Word is actually closed and the file is no longer being used right now I have it working using this word.Visible = true; while (!wordDone) { //gets changed to true on the Quit event System.Threading.Thread.Sleep(100); } bool error = false; do { try { //need to load the contents of the modified file ls.Content = System.IO.File.ReadAllBytes(provider.GetFileName()); error = false; } catch (System.IO.IOException) { error = true; System.Threading.Thread.Sleep(200); } } while (error); while this works it is very ugly, I need a way to fire an event after the Quit event has been handled, or block the current thread while word is still running, or get an event after the document has been saved, the bottom line is I need a clean way to load the file after it has been saved and word is closed. DocumentAfterSave would be awesome, but doesn't seem to exist. I Also tried unhooking the Quit handler and calling word.Quit on the Quit handler, that made no difference

• In Python epoll can I avoid the errno.EWOULDBLOCK, errno.EAGAIN ?

Because it cause to much time to rasie/handle the exception.

• Redirect to new page if cookie doesn't exist or if the value of cookie is 'false'

  - by liquilife

  I have a DOB 'Are you over 18' script which when the form is filled out, validates if they are over 18 or not for a tobacco site I am working on. When this form is filled it stores a cookie 'ageCheck' with a value of either true or false. I'm having some issues with a bit of javascript which is stored on all the pages to determine if they can view the page or if they need to be redirected to the verification page. The javascript is supposed to set a div ID to 'display:block' if passed and if no cookie is found OR the cookie value is false is supposed to redirect them to the age verification page. However, it's just not working. I see the cookies are set correctly. Below is my code.. any help is appreciated. <script> document.body.onload = function() { var ageCheck = getCookie('ageCheck'); if ('true' == ageCheck) { document.getElementById('content').style.display = ''; } else { document.location = '/ageCheck.html'; } } function getCookie(c_name) { if (document.cookie.length > 0) { c_start = document.cookie.indexOf(c_name + "="); if (c_start != -1) { c_start = c_start + c_name.length + 1; c_end = document.cookie.indexOf(";", c_start); if (c_end == -1) c_end = document.cookie.length; return unescape(document.cookie.substring(c_start, c_end)); } } return ""; } </script>

• Parsing XML via jQuery, nested loops

  - by Coughlin

  I am using jQuery to parse XML on my page using $.ajax(). My code block is below and I can get this working to display say each result on the XML file, but I am having trouble because each section can have MORE THAN ONE and im trying to print ALL grades that belong to ONE STUDENT. Here is an example of the XML. <student num="505"> <name gender="male">Al Einstein</name> <course cid="1">60</course> <course cid="2">60</course> <course cid="3">40</course> <course cid="4">55</course> <comments>Lucky if he makes it to lab, hopeless.</comments> </student> Where you see the I am trying to get the results to print the grades for EACH student in each course. Any ideas on what I would do? Thanks, Ryan $.ajax({ type: "GET", url: "final_exam.xml", dataType: "xml", success: function(xml) { var student_list = $('#student-list'); $(xml).find('student').each(function(){ $(xml).find('course').each(function(){ gradeArray = $(this).text(); console.log(gradeArray); }); var name = $(this).find("name").text(); var grade = $(this).find("course").text(); var cid = $(this).find("course").attr("cid"); //console.log(cid); student_list.append("<tr><td>"+name+"</td><td>"+cid+"</td><td>"+grade+"</td></tr>"); }); } });

• C# Working with Locking and Threads

  - by aherrick

  Work on this small test application to learn threading/locking. I have the following code, I would think that the line should only write to console once. However it doesn't seem to be working as expected. Any thoughts on why? What I'm trying to do is add this Lot object to a List, then if any other threads try and hit that list, it would block. Am i completely misusing lock here? class Program { static void Main(string[] args) { int threadCount = 10; //spin up x number of test threads Thread[] threads = new Thread[threadCount]; Work w = new Work(); for (int i = 0; i < threadCount; i++) { threads[i] = new Thread(new ThreadStart(w.DoWork)); } for (int i = 0; i < threadCount; i++) { threads[i].Start(); } // don't let the console close Console.ReadLine(); } } public class Work { List<Lot> lots = new List<Lot>(); private static readonly object thisLock = new object(); public void DoWork() { Lot lot = new Lot() { LotID = 1, LotNumber = "100" }; LockLot(lot); } private void LockLot(Lot lot) { // i would think that "Lot has been added" should only print once? lock (thisLock) { if(!lots.Contains(lot)) { lots.Add(lot); Console.WriteLine("Lot has been added"); } } } }

• Parallel WCF calls to multiple servers

  - by gregmac

  I have a WCF service (the same one) running on multiple servers, and I'd like to call all instances in parallel from a single client. I'm using ChannelFactory and the interface (contract) to call the service. Each service has a local <endpoint> client defined in the .config file. What I'm trying to do is build some kind of generic framework to avoid code duplication. For example a synchronous call in a single thread looks something like this: Dim remoteName As String = "endpointName1" Dim svcProxy As ChannelFactory(Of IMyService) = New ChannelFactory(Of IMyService)(remoteName) Try svcProxy.Open() Dim svc As IMyService = svcProxy.CreateChannel() nodeResult = svc.TestRemote("foo") Finally svcProxy.Close() End Try The part I'm having difficulty with is how to specify and actually invoke the actual remote method (eg "TestRemote") without having to duplicate the above code, and all the thread-related stuff that invokes that, for each method. In the end, I'd like to be able to write code along the lines of (consider this psuedo code): Dim results as Dictionary(Of Node, ExpectedReturnType) results = ParallelInvoke(IMyService.SomeMethod, parameter1, parameter2) where ParallelInvoke() will take the method as an argument, as well as the parameters (paramArray or object() .. whatever) and then go run the request on each remote node, block until they all return an answer or timeout, and then return the results into a Dictionary with the key as the node, and the value as whatever value it returned. I can then (depending on the method) pick out the single value I need, or aggregate all the values from each server together, etc. I'm pretty sure I can do this using reflection and InvokeMember(), but that requires passing the method as a string (which can lead to errors like calling a non-existing method that can't be caught at compile time), so I'd like to see if there is a cleaner way to do this. Thanks

• UIAlertViewDelegate method didDismissWithButtonIndex gets called while the phone is sleeping/locked.

  - by Rob

  I have a UIAlertView who's didDismissWithButtonIndex delegate method calls pops the view controller (same class, it's the alertview delegate and the viewcontroller) to return the user to the previous screen. The issue is that when you lock the phone before the [alert show]; is called, something is calling didDismissWithButtonIndex while the phone is locked. Since the response to that is to pop the view controller, which releases and deallocs it, I crash on the callback. What is causing this phantom button press? Seems like a framework bug, but I hate jumping to that conclusion. I'm definitely not hitting the button, because I hit a breakpoint in my code right before it's displayed. Then I lock the phone. Then I continue. I see it do the show, return to the event loop, and then, while the phone is still locked, hit my breakpoint in didDismissWithButtonIndex. There are a few internet/forum postings about similar spurious delegate calls, but no concrete answers. This is on the simulator, and the device, both OS 2.2 and OS 3.0. I'm assuming I'm missing something, but what? Update: Yeah, I created a simple project with just two view controllers, where when the 2nd view controller displays it creates the alert, and shows it. Then I NSLog in the delegate method, and when the phone is locked, it fires once while locked, and then again when it's unlocked and the button is clicked...2 log messages. But when not locked, there's only one. I guess I'll open an issue, but it seems awfully obvious to have survived this long without anyone complaining. :-) I'm going to try and work around it by making an isActive flag value when the willResignActive/didBecomeActive notifications arrive, and if the app isn't active skipping the delegate body. Update I went ahead in July after I posted this and created radar 7097363 for this issue. There's been no response. The workaround in practice works quite well, checking the active status when processing the delegate, and skipping the action if the the app is inactive.

• shouldAutorotateToInterfaceOrientation won't work!

  - by Dror Sabbag

  Hey. I've been writing my Universal application in portrait mode, and now after about 15 nib files, many many viewCotnrollers, i'd like to implement the shouldAutorotateToInterfaceOrientation and desing some screens in Landscape mode. adding : - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } to ALL of my viewControllers, does not do the work. During Debug, i see that this method is called, but it just won't work! not in the simulator, not in the device, not in Iphone, not in Ipad! i've searched some answers in the forum, and saw some advises to use: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ); } Didn't worked either, adding: [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; and [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications]; to my viewDidLoad and viewDidUnload respectively didn't worked either. I'm lost.. Any help will do! just one more info... all my Views are of type UIControl, as i needed the TuchUpInside to work. Appriciate your help.

• Why is my Android app camera preview running out of memory on my AVD?

  - by Bryan

  I have yet to try this on an actual device, but expect similar results. Anyway, long story short, whenever I run my app on the emulator, it crashes due to an out of memory exception. My code really is essentially the same as the camera preview API demo from google, which runs perfectly fine. The only file in the app (that I created/use) is as below- package berbst.musicReader; import java.io.IOException; import android.app.Activity; import android.content.Context; import android.hardware.Camera; import android.os.Bundle; import android.view.SurfaceHolder; import android.view.SurfaceView; /********************************* * Music Reader v.0001 * Still VERY under construction. * @author Bryan * *********************************/ public class MusicReader extends Activity { private MainScreen main; @Override //Begin activity public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); main = new MainScreen(this); setContentView(main); } class MainScreen extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder sHolder; Camera cam; MainScreen(Context context) { super(context); //Set up SurfaceHolder sHolder = getHolder(); sHolder.addCallback(this); sHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceCreated(SurfaceHolder holder) { // Open the camera and start viewing cam = Camera.open(); try { cam.setPreviewDisplay(holder); } catch (IOException exception) { cam.release(); cam = null; } } public void surfaceDestroyed(SurfaceHolder holder) { // Kill all our crap with the surface cam.stopPreview(); cam.release(); cam = null; } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { // Modify parameters to match size.

• Nexus One & Windows XP USB Driver

  - by Stefan

  I've been unable to get my Nexus One working as a development phone on Windows XP. I've got the driver (revision 3 for N1 support), I've got it installed according to the official installation guide, and the phone appears in the Device Manager just as the guide says it should. However, adb still can't find the phone. 'adb devices', for example, returns no active devices. Am I forgetting some basic step? One thing I've noticed is that the driver is labeled in Windows as version 2 released November, 2009 (I need version 3 from January 2010 for N1 support). However, I've never had version 2 installed. I've used the SDK to download version 3 several times - even deleted it and redownloaded it. I've uninstalled/reinstalled the version 3 driver multiple times. It still says version 2. Is this the problem, or this something completely unrelated? Note: The phone is working as a dev phone on Ubuntu, so I know the phone/cable/etc. are good. It's either my fault or the driver's.

• Thread resource sharing

  - by David

  I'm struggling with multi-threaded programming... I have an application that talks to an external device via a CAN to USB module. I've got the application talking on the CAN bus just fine, but there is a requirement for the application to transmit a "heartbeat" message every second. This sounds like a perfect time to use threads, so I created a thread that wakes up every second and sends the heartbeat. The problem I'm having is sharing the CAN bus interface. The heartbeat must only be sent when the bus is idle. How do I share the resource? Here is pseudo code showing what I have so far: TMainThread { Init: CanBusApi =new TCanBusApi; MutexMain =CreateMutex( "CanBusApiMutexName" ); HeartbeatThread =new THeartbeatThread( CanBusApi ); Execution: WaitForSingleObject( MutexMain ); CanBusApi->DoSomething(); ReleaseMutex( MutexMain ); } THeartbeatThread( CanBusApi ) { Init: MutexHeart =CreateMutex( "CanBusApiMutexName" ); Execution: Sleep( 1000 ); WaitForSingleObject( MutexHeart ); CanBusApi->DoHeartBeat(); ReleaseMutex( MutexHeart ); } The problem I'm seeing is that when DoHeartBeat is called, it causes the main thread to block while waiting for MutexMain as expected, but DoHeartBeat also stops. DoHeartBeat doesn't complete until after WaitForSingleObject(MutexMain) times out in failure. Does DoHeartBeat execute in the context of the MainThread or HeartBeatThread? It seems to be executing in MainThread. What am I doing wrong? Is there a better way? Thanks, David

• iPhone openGLES performance tuning

  - by genesys

  Hey there! I'm trying now for quite a while to optimize the framerate of my game without really making progress. I'm running on the newest iPhone SDK and have a iPhone 3G 3.1.2 device. I invoke arround 150 drawcalls, rendering about 1900 Triangles in total (all objects are textured using two texturelayers and multitexturing. most textures come from the same textureAtlasTexture stored in pvrtc 2bpp compressed texture). This renders on my phone at arround 30 fps, which appears to me to be way too low for only 1900 triangles. I tried many things to optimize the performance, including batching together the objects, transforming the vertices on the CPU and rendering them in a single drawcall. this yelds 8 drawcalls (as oposed to 150 drawcalls), but performance is about the same (fps drop to arround 26fps) I'm using 32byte vertices stored in an interleaved array (12bytes position, 12bytes normals, 8bytes uv). I'm rendering triangleLists and the vertices are ordered in TriStrip order. I did some profiling but I don't really know how to interprete it. instruments-sampling using Instruments and Sampling yelds this result: http://neo.cycovery.com/instruments_sampling.gif telling me that a lot of time is spent in "mach_msg_trap". I googled for it and it seems this function is called in order to wait for some other things. But wait for what?? instruments-openGL instruments with the openGL module yelds this result: http://neo.cycovery.com/intstruments_openglES_debug.gif but here i have really no idea what those numbers are telling me shark profiling: profiling with shark didn't tell me much either: http://neo.cycovery.com/shark_profile_release.gif the largest number is 10%, spent by DrawTriangles - and the whole rest is spent in very small percentage functions Can anyone tell me what else I could do in order to figure out the bottleneck and could help me to interprete those profiling information? Thanks a lot!

  I am wondering why in the following example the top and bottom padding has no affect on the anchor tag while the left and right does? <ul id="nav"> <li><a href="#">One</a></li> <li><a href="#">Two</a></li> <li><a href="#">Three</a></li> <li><a href="#">Four</a></li> <li><a href="#">Five</a></li> </ul> #nav{ list-style:none; } #nav li{ border:1px solid #666; display:inline; /*If you do it this way you need to set the top and bottom padding to be the same here as under #nav li a padding:8px 0; */ } #nav li a{ padding:8px 16px; } Example: Link So my main question is, why does the top and bottom padding not have an effect on the list items while the left and right do? I did try this out with a float instead of a display:inline on the list item and it worked as I expected it to. So I guess if I had a secondary question it would be what is the difference between a float:left; and a display:inline? I was reading the float spec and it sounds like a float is still a box online inline so somewhat like inline-block? I appreciate any input, this isn't really something I need to know to finish a project or anything, but I would like to know why. Thanks Levi

• Problem with JSONResult

  - by vikitor

  Hi, I' still newby to this so I'll try to explain what I'm doing. Basically what I want is to load a dropdownlist depending on the value of a previous one, and I want it to load the data and appear when the other one is changed. This is the code I've written in my controller: public ActionResult GetClassesSearch(bool ajax, string phylumID, string kingdom){ IList<TaxClass> lists = null; int _phylumID = int.Parse(phylumID); int _kingdom = int.Parse(kingdom); lists = _taxon.getClassByPhylumSearch(_phylumID, _kingdom); return Json(lists.count); } and this is how I call the method from the javascript function: function loadClasses(_phylum) { var phylum = _phylum.value; $.getJSON("/Suspension/GetClassesSearch/", { ajax: true, phylumID: phylum, kingdom: kingdom }, function(data) { alert(data); alert('no fallo') document.getElementById("pClass").style.display = "block"; document.getElementById("sClass").options[0] = new Option("-select-", "0", true, true); //for (i = 0; i < data.length; i++) { // $('#sClass').addOption(data[i].classID, data[i].className); //} }); } The thing is that just like this it works, I pass the function the number of classes within a selected phylum, and it displays the pclass element, the problem gets when I try to populate the slist with data (which should contain the objects retrieved from the database), because when there is data returned by the database changing return Json(lists) instead of return Json(lists.count) I keep getting the same error: A circular reference was detected while serializing an object of type 'SubSonic.Schema.DatabaseColumn'. I've been going round and round debugging and making tests but I can't make it work, and it is suppossed to be a simple thing, but I'm missing something. I have commented the for loop because I'm not quite sure if that's the way you access the data, because I've not been able to make it work when it finds records. Can anyone help me? Thanks in advance, Victor

• Best method of achieving bi-directional communication between Apple iPad "clients" and a Windows Ser

  - by user361910

  We are currently starting to build a client-server system which will see 10 or more Apple iPad client devices communicating to a central Windows server over a wireless LAN. We wanted to some existing plumbing (.NET remoting/WCF/web services/etc) that would allow us to implement a reliable, secure solution without having to start at a low level (e.g. sockets) and recreate the wheel. One of the major requirements that complicates this scenario is that unlike a traditional web service, the windows server needs to be able to arbitrarily notify the clients whenever certain events occur -- so it is not a simple request/response scenario like the web. Initially, we were going to use Windows clients, so our plan was to use the full-duplex mode of .NET WCF over HTTP|TCP. But now using the iPad, we don't have any of the WCF infrastructure. So my question is: what is the best way to allow an iPad and a Windows server to (securely) communicate over a LAN, with each device able to initiate communication to the other? Am I stuck writing low-level socket code? Thanks!

• Android media thumbnails. Serious issues?

  - by Ralphleon

  I've been playing with android's thumbnails for a while now, and I've seen some inconsistencies that make me want to scream. My goal is to have a simple list of all Images (and a separate list for video) with the thumbnail and filename. Device: HTC Evo (fresh from Google I/o) First off: http://androidsamples.blogspot.com/2009/06/how-to-display-thumbnails-of-images.html That code doesn't seem to work at all, thumbnails are duplicated... some with the "mirror" effect and some without. Also some won't load and just display a black square. I've tried rebuilding the thumbnails by deleting the "alblum thumbs" directory from the SD card. HTC's gallery application seem to show everything fine. This approach seems to work: Bitmap thumb = MediaStore.Images.Thumbnails.getThumbnail( getContentResolver(), id, MediaStore.Video.Thumbnails.MICRO_KIND, null); imageView.setImageBitmap(curThumb); where id is the original images id and imageView is some image view. This is great! But, strangely, way too slow to be used inside a SimpleViewBinder. Next approach: String [] proj = {MediaStore.Images.Thumbnails._ID}; Cursor c = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, proj, MediaStore.Images.Thumbnails.IMAGE_ID + "=" +id , null, null); if (c != null && c.moveToFirst()) { Uri thumb = Uri.withAppendedPath(mThumbUri,c.getLong(0)+""); imageView.setImageURI(thumb); } I should explain that I feel the needed WHERE condition is required because there doesn't seem to be any guarantee that your uri will have the same ID for both a thumbnail and its parent image. This works for all of the current images, but as soon as I start adding pictures with the camera they show up as blank! Debugging shows a dreaded: SkImageDecoder::Factory returned null error and the URI is returned as invalid. These are the same images that work with the previous call. Can anyone either catch my logical failure or point me to some working code?

• How to Determine The Module a Particular Exception Class is Defined In

  - by doug

  Note: i edited my Q (in the title) so that it better reflects what i actually want to know. In the original title and in the text of my Q, i referred to the source of the thrown exception; what i meant, and what i should have referred to, as pointed out in one of the high-strung but otherwise helpful response below, is the module that the exception class is defined in. This is evidenced by the fact that, again, as pointed out in one of the answers below the answer to the original Q is that the exceptions were thrown from calls to cursor.execute and cursor.next, respectively--which of course, isn't the information you need to write the try/except block. For instance (the Q has nothing specifically to do with SQLite or the PySQLite module): from pysqlite2 import dbapi2 as SQ try: cursor.execute('CREATE TABLE pname (id INTEGER PRIMARY KEY, name VARCHARS(50)') except SQ.OperationalError: print("{0}, {1}".format("table already exists", "... 'CREATE' ignored")) # cursor.execute('SELECT * FROM pname') while 1: try: print(cursor.next()) except StopIteration: break # i let both snippets error out to see the exception thrown, then coded the try/finally blocks--but that didn't tell me anything about which module the exception class is defined. In my example, there's only a single imported module, but where there are many more, i am interested to know how an experienced pythonista identifies the exception source (search-the-docs-till-i-happen-to-find-it is my current method). [And yes i am aware there's a nearly identical question on SO--but for C# rather than python, plus if you read the author's edited version, you'll see he's got a different problem in mind.]

• Computed width with decimal values in Firefox, but without decimals in Webkit

  - by jävi

  Hello one more time! I have a strange problem working with HTML,CSS in different browsers: Firefox 3.6 and Webkit browsers (Chrome & Safari). My HTML looks like this: <div class="ln-letters"> <a href="#" class="all">ALL</a> <a href="#" class="a">A</a> <a href="#" class="b">B</a> <a href="#" class="c">C</a> </div> And my CSS is... .ln-letters a { font-family: 'Lucida Grande'; font-size:14px; display:block; float:left; padding:0px 7px; border-left:1px solid silver; border-right:none; text-decoration:none; } So as you can guess, each anchor gets a different width depending on its inner text. For example the first element with the text 'ALL' will be bigger (more width) than the others. Now the problem is that in Firefox (using Firebug) I can see that the computed width for the first element is 26.5667px, while in Chrome (using Chrome's developer tools) the computed width for the same element is exactly 27px. Therefore the div.ln-letters ends with different widths in each browser and that is causing me some troubles. Question is: there is any workaround to avoid Firefox computing decimal values? Or the opposite: to force Chrome to compute decimal values? Thank you in advance!

• Android USB driver for Xperia X10a

  - by mlohbihler

  I've been trying for a couple hours now, and have hit all of the sites Google found, but i cannot get the Android USB driver on my XP box to talk to my new Xperia X10a. I found the lines that some kind soul posted, and has been syndicated repeated, but they don't work for me. The idea is to add them to the Google.NTx86 and Google.NTamd64 sections of the android_winusb.inf file: ;Xperia X10 %SingleAdbInterface% = USB_Install, USB\VID_0FCE&PID_E12E %CompositeAdbInterface% = USB_Install, USB\VID_0FCE&PID_E12E&MI_01 I tried a number of variations of the first line, including "Sony Ericsson X10a", which is what XP shows me in both the "found new hardware" wizard and the device manager, but no luck. The result is always the same. Here are my steps: Plug in the phone via USB "found new hardware wizard" appears Choose "No, not this time" and "next" Choose "Install from a list or specific location..." and "next" Choose "Search for best driver...", check "Include this location...", and browse for the "usb_driver" folder in the Android SDK installation. Click "next" It does a quick search and then says "Cannot install this hardware", "... because the wizard cannot find the necessary software". I've tried more things that i can recall now, including deleting registry entries, but it just won't work. Any help would be appreciated at this point. Regards, m@
