• VB.NET equivalent of Timeout.bas Module from VB6

  - by user557889

  Hi all. I am looking for the VB.NET code of a very handy little *.bas file I used to use in Visual Basic 6. The file was called timeout.bas and it was the greatest module ever to me. I want to switch to start using VB.NET finally but this single file is holding me back. Trying to use .NET without it is like crippling me. Can someone, anyone please make this code work in .NET for me? It's only a couple lines: Attribute VB_Name = "Module1" Sub timeout(duration) starttime = Timer Do While Timer - starttime < duration DoEvents Loop End Sub Basically you add that timeout.bas file which contains that code and you can just do: Text1.text = "hello" timeout .5 Text1.text "World!" It's so awesome. Anyone PLEASE re-do it in VB.NET for me! Thanks!

• Order words by number of letters, then place words neatly

  - by bmaster

  I have a list of words in javascript similar to this: var words = ["mine", "minute", "mist", "mixed", "money", "monkey", "month", "moon", "morning", "mother", "motion", "mountain", "mouth", "move", "much", "muscle", "music", "nail", "name", "narrow", "nation", "natural", "near", "necessary", "neck", "need", "needle", "nerve", "net", "new", "news", "night"]; The words can be 1-25? letters long. I have a div id="words", with a set width of 700px (but I might change it from this). Using css/javascript/jquery, how can I make it: Order the words by number of letters Place the words inside the div tag, left to right, but so that there are no gaps at the right edge of the words div, and there is even spacing between words on a line. Each word should have a border around it and a background. Like this: |reallylongwordssdf shorterwordfdf dfsdfsdfsdf sdfsdfsdf| |sdfsdfsdf sdffsdop sdfjpogs sdfsds dfsdsd dfsdsd dfsdsd| I really have no idea where to begin with this. Perhaps I could manage to write code to order the words by number of letters, but after that, I'd be stuck. Edit: I forgot to add, the words must be links.

• CSS overflow detection in JavaScript

  - by ring0

  In order to display a line of text (like in a forum), and end that line with "..." if the text would overflow the line (not truncating using the CSS overflow property), there are a number of ways. I'm still seeking the best solution. For instance, Adding in CSS a "..." as a background-image is a possibility, but it would appear all the time, and this is not a good solution. Some sites just count the characters and if over - say - 100, truncates the string to keep only 100 (or 97) chars and add a "..." at the end. But fonts are usually not proportional, so the result is not pretty. For instance the space - in pixels - taken by "AAA" and "iii" is clearly different "AAA" and "iii" via a proportional font have the same width There is another idea to get the exact size in pixels of the string: create in Javascript a DIV insert the text in it (via innerHTML for instance) measure the width (via .offsetWidth) which is not implemented yet. However, I wonder if there could be any browser compatibility problem? Did any one tried this solution? Other recommendations would be welcome.

• IronPython/C# Float data comparison

  - by Gopalakrishnan Subramani

  We have WPF based application using Prism Framework. We have embedded IronPython and using Python Unit Test framework to automate our application GUI testing. It works very well. We have difficulties in comparing two float numbers. Example class MyClass { public object Value { get; set;} public MyClass() { Value = (float) 12.345; } } In IronPython When I compare the MyClass Instance's Value property with python float value(12.345), it says it doesn't equal This statement raises assert error self.assertEqual(myClassInstance.Value, 12.345) This statement works fine. self.assertEqual(float(myClassInstance.Value.ToString()), 12.345) When I check the type of the type(myClassInstance.Value), it returns Single in Python where as type(12.345) returns float. How to handle the C# float to Python comparison without explicit conversions?

  I am trying to build a C# project (downloaded code) in Visual Studio Express 2008. I get the error (my translation): The type or namespace name "Allegro" couldn't be found. for the line using Allegro; I know the 2D graphics library Allegro, of course, but I can't find much information on how to use it in C#. It is being used for visualization in the project I am trying to compile. I also get the warning This reference couldn't be resolved. The Universal assembly couldn't be found. I haven't been working with C# before and and I barely know Visual Studio Express. These are newbie mistakes - but I just need a fast solution for this problem. Could someone provide me with a short step-by-step solution?

• package issue with ubuntu 10.10 and passenger requirements

  - by user368937

  I'm trying to get Passenger working with Ubuntu 10.10 and I'm running into a problem. It seems that the passenger installer is not recognizing the virtual package. I'm getting this error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... And then it says, run this: * To install OpenSSL support for Ruby: Please run apt-get install libopenssl-ruby as root. When I run the above command, it refers to the libruby package: sudo apt-get install libopenssl-ruby Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libruby' instead of 'libopenssl-ruby' libruby is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 43 not upgraded. When I look at the details for libruby, it says it provides libopenssl-ruby: Code: Provides: libbigdecimal-ruby, libcurses-ruby, libdbm-ruby, libdl-ruby, libdrb-ruby, liberb-ruby, libgdbm-ruby, libiconv-ruby, libopenssl-ruby, libpty-ruby, libracc-runtime-ruby, libreadline-ruby, librexml-ruby, libsdbm-ruby, libstrscan-ruby, libsyslog-ruby, libtest-unit-ruby, libwebrick-ruby, libxmlrpc-ruby, libyaml-ruby, libzlib-ruby And when I rerun the passenger installer, it gives the same error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... Let me know if you need more info. How do I fix this?

  Hi guys, I've a custom UITableViewCell like this: +--------------------------+ | username | | | | --- <image> -- | | | | <like it> | +--------------------------+ It display an username, an image and a button "Like it" to like image.

When you click on the username you'll see a view for user information. The entire cell is not selectable.

• Any way to make DataContractJsonSerializer serialize Dictionaries properly?

  - by morpheus

  The DataContractJsonSerializer is not able to serialize Dictionaries properly. Whereas JavaScriptSerializer serializes Dictionaries as {"abc":"xyz","def":42} for example, the DataContractJsonSerializer gives [{"Key":"abc","Value":"xyz"},{"Key":"def","Value":42}] instead. This is really problematic and I want to know how can I serialize Dictionary objects correctly in my WCF service. I am looking for a solution that would require least amount of effort. ref: http://msdn.microsoft.com/en-us/library/bb412170.aspx

• How to select a MenuItem programatically

  - by Shaung

  I am trying to add a global shortcut to a gtk.MenuItem which has a sub menu. Here is my code: import pygtk, gtk import keybinder dlg = gtk.Dialog('menu test') dlg.set_size_request(200, 40) menubar = gtk.MenuBar() menubar.show() menuitem = gtk.MenuItem('foo') menuitem.show() menubar.append(menuitem) mitem = gtk.MenuItem('bar') mitem.show() menu = gtk.Menu() menu.add(mitem) menu.show() menuitem.set_submenu(menu) def show_menu_cb(): menubar.select_item(menuitem) keybinder.bind('<Super>i', show_menu_cb) dlg.vbox.pack_start(menubar) dlg.show() dlg.run() When I press the key menu pops up, I can then select items in the sub menu or press Esc to make it disappear. But after that the menuitem keeps selected and other windows never get input focus again. I have to click on the menuitem twice to get everything back normal.

• SpeechRecognizer causes ANR... I need help with Android speech API.

  - by Dondo Chaka

  I'm trying to use Android's speech recognition package to record user speech and translate it to text. Unfortunately, when I attempt initiate listening, I get an ANR error that doesn't point to anything specific. As the SpeechRecognizer API indicates, a RuntimeException is thrown if you attempt to call it from the main thread. This would make me wonder if the processing was just too demanding... but I know that other applications use the Android API for this purpose and it is typically pretty snappy. java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread Here is a (trimmed) sample of the code I'm trying to call from my service. Is this the proper approach? Thanks for taking the time to help. This has been a hurdle I haven't been able to get over yet. Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "com.domain.app"); SpeechRecognizer recognizer = SpeechRecognizer .createSpeechRecognizer(this.getApplicationContext()); RecognitionListener listener = new RecognitionListener() { @Override public void onResults(Bundle results) { ArrayList<String> voiceResults = results .getStringArrayList(RecognizerIntent.EXTRA_RESULTS); if (voiceResults == null) { Log.e(getString(R.string.log_label), "No voice results"); } else { Log.d(getString(R.string.log_label), "Printing matches: "); for (String match : voiceResults) { Log.d(getString(R.string.log_label), match); } } } @Override public void onReadyForSpeech(Bundle params) { Log.d(getString(R.string.log_label), "Ready for speech"); } @Override public void onError(int error) { Log.d(getString(R.string.log_label), "Error listening for speech: " + error); } @Override public void onBeginningOfSpeech() { Log.d(getString(R.string.log_label), "Speech starting"); } }; recognizer.setRecognitionListener(listener); recognizer.startListening(intent);

• MPMoviePlayerController switching movies causes white flash

  - by bennythemink

  Hi guys, I have a small UIView that displays a repeated movie. When the user taps a button another movie is loaded and displayed in the same UIView. The problem is that there is a half second "flash" between the removing of the first movie and the displaying of the second. Is there any to remove this? <code> - (void) setUpMovie:(NSString*)title { NSString *url = [[NSBundle mainBundle] pathForResource:title ofType:@"mp4"]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]]; [[player view] setFrame:self.movieView.bounds]; [self.movieView addSubview:player.view]; if ([title isEqualToString:@"Bo_idle_02"]) { [player setRepeatMode:MPMovieRepeatModeOne]; } else { [player setRepeatMode:MPMovieRepeatModeNone]; } [player setControlStyle:MPMovieControlStyleNone]; [player play]; } - (void) startDanceAnimation { [self setUpMovie:@"Bo_dance_02"]; return; } </code>

• The Missing Post

  - by Joe Mayo

  It’s somewhat of a mystery how the writing process can conjure up results that weren’t initially intended. Case in point is the fact that another post was planned to be in place of this one, but it never made the light of day.  This particular post started off as an introduction to a technology I had just learned, used, and wanted to share the experience with others.  The beginning was fun and demonstrated how easy it was to get started.  One of the things I’ve been pondering over time is that the Web is filled with introductions to new technologies and quick first looks, so I set out to add more depth, share lessons learned, and generally help you avoid the problems I encountered along the way; problems being a key theme of why you aren’t reading that post at this very minute.  Problems that curiously came from nowhere to thwart my good intentions. Success was sweet when using the tool for the prototypical demo scenario. The thing is, I intended the tool to accomplish a real task.  Having embarked on the path toward getting the job done, glitches began creeping into the process.  Realizing that this was all a bit new, I had patience and found a suitable work-around, but this was to be short lived. As in marching ants to a freshly laid out picnic, the problems kept coming until I had to get up and walk away.  Not to be outdone, sheer will and brute force manual intervention led to mission accomplishment.  Though I kept a positive outlook and was pleased at the final result, the process of using the tool had somewhat soured. Regardless of a less than stellar experience with the tool, I have a great deal of respect for the company that produced it and the people who built it. Perhaps I empathize for what they might feel after reading a post that details such deficiencies in their product.  Sure, if you’re in this business, you’ve got to have a thick skin; brush it off, fix the problem, and move on to greatness. But, today I feel like they’re people and are probably already aware of any issues I would seemingly reveal.  Anyone who builds a product or provides a service takes a lot of pride in what they do.  Sometimes they screw up and if their worth a dime, they make it up. I think that will happen in this case and there’s no reason why I should post information that has the potential to sound more negative than helpful.  While no one would ever notice or care either way, I’m posting something that won’t harm.

• logrotate isn't rotating a particular log file (and i think it should be)

  - by Max Williams

  Hi all. For a particular app, i have log files in two places. One of the places has just one log file that i want to use with logrotate, for the other location i want to use logrotate on all log files in that folder. I've set up an entry called millionaire-staging in /etc/logrotate.d and have been testing it by calling logrotate -f millionaire-staging. Here's my entry: #/etc/logrotate.d/millionaire-staging compress rotate 1000 dateext missingok sharedscripts copytruncate /var/www/apps/test.millionaire/log/staging.log { weekly } /var/www/apps/test.millionaire/shared/log/*log { size 40M } So, for the first folder, i want to rotate weekly (this seems to have worked fine). For the other, i want to rotate only when the log files get bigger than 40 meg. When i look in that folder (using the same locator as in the logrotate config), i can see a file in there that's 54M and which hasn't been rotated: $ ls -lh /var/www/apps/test.millionaire/shared/log/*log -rw-r--r-- 1 www-data root 33M 2010-12-29 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stderr.log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stdout.log Some of the other log files in that folder have been rotated though: $ ls -lh /var/www/apps/test.millionaire/shared/log total 91M -rw-r--r-- 1 www-data root 33M 2010-12-29 15:05 test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stderr.log -rw-r--r-- 1 deploy deploy 41K 2010-12-29 11:03 unicorn.stderr.log-20101229.gz -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stdout.log -rw-r--r-- 1 deploy deploy 1.1K 2010-10-15 11:05 unicorn.stdout.log-20101229.gz I think what might have happened is that i first ran this config with a pattern matching *.log, and that means it only rotated the two files that ended in .log (as opposed to -log). Then, when i changed the config and ran it again, it won't do any more since it think's its already had its weekly run, or something. Can anyone see what i'm doing wrong? Is it to do with those top folders being owned by root rather than deploy do you think? thanks, max

• Best Small Linux Distribution for rDesktop

  - by d2jxp

  What would be the best linux distribution to use just for the purpose of rDesktop? We're trying to decide if we should get rid of old computers or just use them as thin-clients to connect to virtual Windows 7 machines on our network. I would like something with as little bloat as possible and can be run from a USB flash drive. I have tried SliTaz, ThinStation, and Pixil from Century Software. SliTaz has been my favorite so far but I still want to know if there's something better that's also easily customizable.

• Need some help figuring out BB4Win or any of its varieties: does it replace windows explorer?

  - by StormRyder

  I don't really care too much about replacing original Windows the desktop, taskbar and system tray. I really dislike the new Win7/Vista Windows Explorer: Screenshot here (just to make sure there's no confusion) So, what I'm trying to figure out is whether BB4Win or its plugins have a replacement for it. The bb4win website pretty much doesn't make sense to me. I'm using Win7 64 bit. Also, off-topic ... I was looking at a related question on this site here: Good Windows shell replacement Why can't I add comments? I wanted to ask the same question I'm asking now as a comment under the answer given by Molly7244, the person who answered with suggesting BB4Win. But there seems to be no way to add new comments anywhere! Why? Am I missing something? I don't quite understand the weird way this site is set up... I'm used to the more typical forum format. Sorry. Thanks for any help!

• Mac OSX - looking for software for notes, snippets, ideas, etc.

  - by eatloaf

  I have the following requirements: Mobile accessibility: Either a complimentary iphone app to sync with, or DropBox or Google Docs syncing or equivalent so I can use other mobile note applications to edit notes remotely. Minimally some form of markup, but ideally something I can drag and drop images into and do some formatting. Rich Text support is reasonable. Hierarchical organization, AKA outlining. Internal (note to note) linking. I like to cross reference items and thoughts internally and the relationships aren't always hierarchical. These were closest to what I was looking for but, as far as I can tell, suffer from the noted flaws: Mori : No mobile solution. EagleFiler : No item hierarchy. MacJournal : No entry hierarchy. iphone app converts edited entries to plain text. Evernote : No interior linking. No hierarchy. I think I've tried every serious contender and none of them have all four (seemingly simple) requirements. I'm hoping that I'm either missing an existing feature in an app I've tried or that someone knows of something I haven't found it yet.

• Windows 7: How to change the taskbar font size

  - by Noah

  Windows 7 (Aero) does not offer an option to easily change the taskbar font size. BACKGROUND: I was using an increased DIP 125%. The problem being that many programs, sad to say, Microsoft's included, don't scale or position properly at other than 100%. I've reset the DPI to 100%, and have been able to customize most of my windows settings for easy reading, except the task bar font size In Summary: There are many ways to change the taskbar font color. I'm looking to increase the actual font size.
