• Asynchronous Html.ImageGetter for setting multiple images in a TextView

  - by thedude19

  I'm writing an application that takes HTML pages and parses them to display on the screen. Specifically, this application pulls HTML from a message board and lists posts made by users. The problem is that a lot of the content in posts are pictures in <img> tags, so I need to write a Html.ImageGetter to handle the downloading of the images. My textView.setText() method will look like this: myTextView.setText(Html.fromHtml(myText, new ImageGetter() { @Override public Drawable getDrawable(String source) { Drawable d; // Need to async download image here return d; } }, null)); Doing this synchronously is trivial, but is there a suggested way to do this asynchronously so that it doesn't lock up my UI thread? I would also like to eventually build in caching of these images, but I imagine that would be pretty simple once the async downloading was there.

• Server compromised. Bounce message contains many email addresses message was not sent to

  - by Tim Duncklee

  This is not a dupe. Please read and understand the issue before marking this as a duplicate question that has been answered already. Several customers are reporting bounce messages like the one below. At first I thought their computers had a virus but then I received one that was server generated so the problem is with the server. I've inspected the logs and these email addresses do not appear in the logs. The only thing I see that I do not remember seeing in the past are entries like this: Apr 30 13:34:49 psa86 qmail-queue-handlers[20994]: hook_dir = '/var/qmail//handlers/before-queue' Apr 30 13:34:49 psa86 qmail-queue-handlers[20994]: recipient[3] = '[email protected]' Apr 30 13:34:49 psa86 qmail-queue-handlers[20994]: handlers dir = '/var/qmail//handlers/before-queue/recipient/[email protected]' I've searched here and the web and maybe I'm just not entering the right search terms but I find nothing on this issue.

• Using Monitor Class

  - by Mubashar Ahmad

  Dear All I would like to ask couple of Questions regarding the use of Monitor Class in .Net. To understand the Questions please look at the following Code. public class MyClass { private List<int> _MyCollection = new List<int>(); public void GetLock() { Monitor.Enter(_MyCollection); } public void ReleaseLock() { Monitor.Exit(_MyCollection); } public void UpdateCollection(/*anyparam*/) { //update collection without lock on collection } } public class MyAppMain { private static MyClass myclass = new MyClass(); public static void main(args) { try { myclass.GetLock(); //an operation that does not do any update on myclass but wanted //to ensure that the collection within myclass never update //while its doing following opetion //Do somthing } finally { myclass.ReleaseLock(); } } } Now is this the right use of monitor and do i need to use Pulse or PulseAll to signal waiting thread and if so than should use plus before or after Exit function? Regards Mubashar

• Updating the icons in an ObjectListView

  - by Eric

  I'm using an TreeListView (a sub type of ObjectListView) in my current project. Each item in the list is given an icon, but the icon my vary depending on the state of the item. For example if the item is readonly I want to use an icon with a little lock symbol. When the items are first added to the TreeListView the icons are show correctly, yet later when the state of an item changes the icons are not updating. How do I force the control to regenerate all the icons?

• Are there alternatives to UltraWinGrid (for C#)?

  - by MPelletier

  I've been using the Infragistics UltraWinGrid for a while in a C# project, and while it's very spiffy, it is sometimes a bit heavy to run (and editing it in Visual Studio can be hazardous). I'm looking for a lighter alternative. Looks (always a big plus with Infragistics) are not as important as functionality. Namely, I'm looking for a beefed up DataGridView which: has data binding (duh!) has lock control over editing allows for sub-tables on opening a row can have multiple headers to group columns together (say header 1 is composed of "Group A" and "Group B", and header 2 has various columns under each group) has sorting by column (and can sort numbers properly, even if it does not have a stock method at first) has filtering by column (perhaps the most demanding spec) à la UltraWinGrid/Excel (text field with a way to specify if the filter is equal, not equal, greater, lesser, starts with, ends with, etc). supports check box, text box or data bound list/combo box cells allows cells to be merged (not the control cells of course!) can have events bound to each row (say double click)

• Eventlet client-server

  - by johannix

  I'm trying to setup a server-client interraction: Server gets a string from client Server returns data to client I got this working with socket.send and socket.recv, but was wondering how to get it working with files through socket.makefile. I've got most of the pieces working, but don't know how to force each of the pieces to read at the appropriate time. So what it looks like is happening is that both the client and server are reading on the socket at the same time. Any ideas on how to let the server complete the original read before the client starts waiting for its information? Below are the core pieces that reproduce the read lock. Server: def handle(green_socket): file_handler = green_socket.makefile('rw') print 'before server read' lines = file_handler.readlines() print "readlines: %s" % (lines) print '** Server started **' server = eventlet.listen((HOST, PORT)) pool = eventlet.GreenPool() while True: new_sock, address = server.accept() pool.spawn_n(handle, new_sock) Client: from eventlet.green import socket green_socket = eventlet.connect((HOST, PORT)) file_handler = green_socket.makefile('rw') print 'before write' file_handler.writelines('client message') file_handler.flush() print 'before client read' lines = file_handler.readlines()

• Fluent NHibernate OptimisticLock.None() causes "The string 'none' is not a valid Boolean value."

  - by David Thomas Garcia

  I'm using the following mapping: public class LoadMap : IAutoMappingOverride<Load> { public void Override(AutoMapping<Load> mapping) { mapping.HasMany(x => x.Bids).OptimisticLock.None(); mapping.Version(x => x.Version); } } But when I try to create the session I get the following exception: [FormatException: The string 'none' is not a valid Boolean value.] [XmlSchemaValidationException: The 'optimistic-lock' attribute is invalid - The value 'none' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:boolean' - The string 'none' is not a valid Boolean value.] I'm using NHibernate 2.1.2.4000 and I was using Fluent NHibernate 1.0RTM, but tried the latest build 636 just to be sure this isn't something that was fixed recently or something. As a side note, in case I'm doing this all wrong, I would like to be able to make changes to the .Bids list without incrementing Version. I saw an example on Ayende's blog that did what I wanted with properties.

• Delphi and prevent event handling

  - by pKarelian

  How do you prevent a new event handling to start when an event handling is already running? I press a button1 and event handler start e.g. slow printing job. There are several controls in form buttons, edits, combos and I want that a new event allowed only after running handler is finnished. I have used fRunning variable to lock handler in shared event handler. Is there more clever way to handle this? procedure TFormFoo.Button_Click(Sender: TObject); begin if not fRunning then try fRunning := true; if (Sender = Button1) then // Call something slow ... if (Sender = Button2) then // Call something ... if (Sender = Button3) then // Call something ... finally fRunning := false; end; end;

• Writing data over RxTx using usbserial?

  - by Jeach

  I'm using the RxTx library over usbserial on a Linux distro. The RxTx lib seems to behave quite differently (in a bad way) than how it works over serial. One of my biggest problems is that the RxTx SerialPortEvent.OUTPUT_BUFFER_EMPTY does not work on linux over usbserial. How do I know when I should write to the stream? Any indicators I might have missed? So far my experience with writing and reading concurrently have not been great. Does anyone know if I should lock the DATA_AVAILABLE handler from being invoked while I'm writing on the stream? Or RxTx accepts concurrent read/writes? Thanks in advance

• iPhone Settings app and keyboard control?

  - by randallmeadows

  So I'm putting my app's preference settings into the Settings app. One of the settings is an edit text field (PSTextFieldSpecifier). When touched, the keyboard dutifully appears, I can make the edits, but when I press Return....nothing. Well, the editing is completed, but the keyboard remains. I see no way to make the keyboard go away. I also notice this same behavior in other Settings panes, including those from Apple. Do I assume correctly that this is just standard behavior and I need to just accept the fact that my Settings table has now been reduced to half size, and just deal? Furthermore, I gather there is no approved way to have a "rich" child pane display, such as that seen in Settings-General-About-Legal? Or a way to do what appears to be a -presentModalViewController, a la Settings-General-Passcode Lock?

• Why does ASP.Net locks when I update code with TortoiseSVN

  - by Malartre

  Hi, when I update Adobe Flash/Flex code that is not related to ASP.Net with TortoiseSVN (latest) on a Windows Server 2008, the complete website locks and stop responding. Is it ASP.Net recompiling my code, is it IIS 7 or is it Tortoise locking the file system? How can I prevent or minimize this if I need to do an update when 1000 users are using the ASP.Net website? UPDATE: Thanks to Aito and Bryan, I learned more about AppDomain. I found these two links where I discover that folder creation/deletion recycle the AppDomain in ASP.Net 2. --If TortoiseSVN creates folders in it's hidden .svn folders hierarchy, I guess it will lock the app! ASP.NET v2.0 - AppDomain recycles, more common than before http://weblogs.asp.net/owscott/archive/2006/02/21/ASP.NET-v2.0-2D00-AppDomain-recycles_2C00_-more-common-than-before.aspx FIX: ASP.NET 2.0-connected applications on a Web site may appear to stop responding http://support.microsoft.com/kb/911272 I'm testing this.

  Hello *, I am currently writing a scientific article, where I need to be very exact with citation. Can someone point me to either MSDN, MSDN article, some published article source or a book, where I can find performance comparison of Windows or .NET Synchronization primitives. I know that these are in the descending performance order: Interlocked API, Critical Section, .NET lock-statement, Monitor, Mutex, EventWaitHandle, Semaphore. Many Thanks, Ovanes P.S. I found a great book: Concurrent Programming on Windows by Joe Duffy. This book is written by one of the head concurrency developers for .NET Framework and is simply brilliant with lots of explanations, how things work or were implemented.

• Makecert.exe hangs

  - by Robert

  I was following the steps in Scott Hanselman's blog post describing how to create a certificate authority and code signing certificate for PowerShell scripts. Initially, I created the certificate authority and a personal certifcate and used it to sign a powershell script successfully. All went as described in the blog post. The problem starts (as most do) when I did something that was (probably) stupid, although it seemed reasonable at the time. I wanted to start over and repeat the process again with a clean slate, so from the mmc certificates snap-in console, I deleted the personal certificate and the certificate authority I created previously. After that any time I try to use makecert, (just as I did the first time around), makecert either hangs or faults (which prompts to end or debug). Did I hose something up by deleting via the certificates snap-in? It didn't complain or warn me that it could be potentially hazardous. Is this just coincidence and something else entirely could be hosed? I have Event Log entries from the times when makecert crashed, which all look very similar; here is one: Log Name: Application Source: Application Error Date: 8/5/2009 3:55:04 PM Event ID: 1000 Task Category: (100) Level: Error Description: Faulting application makecert.exe, version 6.0.6000.16384, time stamp 0x4545910b, faulting module ntdll.dll, version 6.0.6002.18005, time stamp 0x49e03821, exception code 0xc0000005, fault offset 0x00067409, process id 0xe58, application start time 0x01ca160efdf30625. Anyone have any ideas as to what exactly caused this and/or what I can do to fix it. I'm on 32-bit Vista Enterprise w/SP2.

• TFS: How to dectet changed files when loading a solution?

  - by marco.ragogna

  I am new to TFS integration with Visual Studio 2010, and I have a problem I would like to solve. Practically, when I open a solution, how can I detect, looking only at the Solution Explorer which file has been changed since my last login? I am able to discover the changed files if I look at the Latest column of Source Control Explorer but it is not so intuitive. I attach you an image for better understanding. I would like to have a different icon, not the lock, for frmAbout.vb (in this case), associated to the item in Solution Explorer. Do you have any idea how can I achieve this behavior? Or some alternatives?

• "SELECT ... FOR UPDATE" not working for Hibernate and MySQL

  - by Andres Rodriguez

  Hi, We have a system in which we must use pessimistic locking in one entity. We are using hibernate, so we use LockMode.UPGRADE. However, it does not lock. The tables are InnoDB We have checked that locking works correctly in the database (5.0.32), so this bug http://bugs.mysql.com/bug.php?id=18184 seems to be no problem. We have checked that datasource includes the autoCommit = false parameter. We have checked that the SQL hibernate (version 3.2) generates includes the " FOR UPDATE". Thanks,

• Where do you store the private key for your code signing certificate?

  - by flipdoubt

  I recently acquired a code signing certificate for my employer, but I am not the InstallShield developer who will sign the binaries before distribution. I know I can export the certificate along with its private key, but where do I store it so the InstallShield developer can install it on his machine? Should I remove it from my machine once I give it to the person doing the signing? Where do I store the master copy? Obviously, source control is not the best place, unless I lock down that directory in SVN.

• Source Control icons have disappeared in Visual Studio 2010

  - by Richard West

  Today I installed Visual Studio 2010 Ultimate - RTM. One item that I noticed that is different is that files listed in the Solution Explorer window not longer display the source control icons beside each file (the lock, unlocked, plus sign for new files, etc.). Is there a setting that I am overlooking to display these icons? I have setup Visual Studio 2010 to use my source control client correctly (SourceGear Vault), and it does appear to be working OK -- I'm just used to seeing the little icons by each file. Anyone out there experiencing this problem? Is there something I can do to get the icons back?

• C# XP Sound QuickFix

But under XP the logic contained within FireAttackProc gets executed but none of the sound clips play. Is there a quick solution to this so the sound will play under XP? I ask for a quick solution because i am happy being able to execute fully in Vista/Win7 but would be great if there was a quick solution so it would be XP compitable also. Thank you.

• Keyboard for programmers

  - by Robert Höglund

  I'm trying to improve my working environment and I'm still searching for that perfect keyboard that practically types bug-free code all by itself. At the moment I'm using a Logitech Wave for my Windows need and an Apple Wireless Keyboard (the one without a numeric keypad) when doing OS X stuff. I'm quite happy with the Logitech Wave but I would prefer one without all the extra multimedia buttons. What I like most about the Apple Wireless Keyboard is that it is very similar to the Macbook's keyboard which for me makes it easier to write code when on my Macbook. What kind of keyboard would you recommend for going all out writing code until your fingers bleed? I have remapped the Caps Lock key to Ctrl which after a while feels really good, until I have to sit at another computer or when someone at work is going to show me something on my computer. Are there other little keyboard tricks that you use to get a little bit more productive? I have looked into switching to Dvorak but I have decided it's not for me.

• Rails: simple bundler question with ruby-openid

  - by Joern Akkermann

  Hi! I just installed the ruby-openid gem and then bundled it by entering gem 'ruby-openid', :require => 'openid' in the gemfile. Then I started bundle install and bundle lock. Everything worked fine so far. But how can I now access the classes of ruby-openid. OpenID::method won't work for me. It raises a not found error. What have I forgot or done wrong? I'm absolutely new to bundler and the internet full of solutions for various versions, but I need one solution that's surely working. I'm thankful for any help!

• Why do Programmers Love/Hate Objective-C?

  - by Genericrich

  So I have noticed that there is a lot of animosity towards Objective-C among programmers. What's your take? Is it a vendor lock-in thing against Apple? General antipathy towards Apple? The syntax? What's your view on this? With the advent of the iPhone SDK, Obj-C has gotten a lot more attention lately, and I am curious what people on SO's opinions are. I personally fought the syntax at first but have gotten more and more used to it now. I really like the named arguments. I have some pet peeves with how things are done in Obj-C vs other languages, but I will refrain from comment on them here.

• PhysX for massive performance via GPU ?

  - by devdude

  I recently compared some of the physics engine out there for simulation and game development. Some are free, some are opensource, some are commercial (1 is even very commercial $$$$). Havok, Ode, Newton (aka oxNewton), Bullet, PhysX and "raw" build-in physics in some 3D engines. At some stage I came to conclusion or question: Why should I use anything but NVidia PhysX if I can make use of its amazing performance (if I need it) due to GPU processing ? With future NVidia cards I can expect further improvement independent of the regular CPU generation steps. The SDK is free and it is available for Linux as well. Of course it is a bit of vendor lock-in and it is not opensource. Whats your view or experience ? If you would start right now with development, would you agree with the above ? cheers
