• Python doesn't work properly when I execute a script after using Right Click >> Command Prompt Here

  - by Dominic Bou-Samra

  This is a weird bug. I know it's something funky going on with my PATH variable, but no idea how to fix it. If I have a script C:\Test\test.py and I execute it from within IDLE, it works fine. If I open up Command Prompt using Runcmd.exe and navigate manually it works fine. But if I use Windows 7's convenient Right Click on folder Command Prompt Here then type test.py it fails with import errors. I also cannot just type "python" to reach a python shell session if I use the latter method above. Any ideas?

• Netbeans 7.2 won't open on OS X

  - by Mark van Wyk

  I installed Netbeans on OSX Mountain Lion running JDK 7. Everything was working fine. Then my machine for no reason crashed. After this I could no longer open Netbeans anymore. If I try to start Netbeans from the commandline: /Applications/NetBeans/NetBeans 7.2.app/Contents/MacOS/netbeans Then it works fine. From there I can select Netbeans About and confirm that my userdir and cachedir is: User directory: /Users/<user>/Library/Application Support/NetBeans/7.2 Cache directory: /Users/<user>/Library/Caches/NetBeans/7.2 So, I deleted these directories and tried again, but alas, I can only start netbeans via the commandline. Ideas appreciated...

• DCVS + hosting for a startup commercial multiplatform phone app

  - by AG

  I'm in lean startup mode, working on a simple phone app that will be published initially as a iThingy app and an Android app with, possibly, Blackberry and Symbian versions to follow. I'm about to go from no repository to needing a central repository that up to 4 very part-time resources will be sharing. Two of us have no version control background, one has used Subversion, and I've used most of the major centralized VCS systems. I'm not going to be pushing the technical limitations of any VCS for a long time; I'm sure that any of the major systems would work fine. And the hosting accounts I've looked at seem reasonable. So I'm really focussed on minimizing the downside risks. That is, I'd like to find a stable setup that is easy to learn in general, easy to use from Windows/Eclipse, and won't paint me into any obvious corners for the next 12 months or so. A quick search of the web had led me to consider the following pairs of DVCS and hosting service, with what I think I'm hearing as their strengths and weaknesses (for my purposes): Bazaar/Launchpad -- My initial choice since I need to get more familiar with this pair for the Google Summer of Code mentoring I'm doing. But, whatever the technical merits, a non-starter for me because they are purely open source, no private repositories plans to purchase that I can see. Git/GitHub -- Git: Fast, light, ultimately flexible, but relatively less Windows friendly, Eclipse plugin (eGit) available but relatively young, GitHub: widely used, pricing is fine Mercurial/BitBucket -- Mercurial: a little less flexible, a little more Windows friendly, Eclipse plugin seems a bit more mature, BitBucket: widely used, pricing is fine, includes a wiki and an issue tracker that we might be able to use instead of something like BaseCamp, at least for a while. Mercurial/BitBucket seem like the winning pair so far for my particular situation; at least two of us are definitely going to be working mostly from Eclipse on Windows and reducing my own learning curve is a priority. ;-) But I have two specific questions: 1) Am I wrong about Bazaar/Launchpad and is there a viable, secure way to use them for proprietary code? 2) Any reason to think that the Mecurial/Bitbucket pair will end up being a headache for my Mac developer, soon, or for Blackberry or Symbian developers a little later? ag

• Stripes link event triggering validation that is incorrect.

  - by Davoink

  I have stripes:link tag in a jsp with an event attribute: <stripes:link href="${actionBean.context.currentStage.stripesForwardAction}" addSourcePage="true" event="showTab2Link"> This triggers the validation to trigger on nested properties: @ValidateNestedProperties({ @Validate(field="county", required=true, minlength=2, maxlength=2, mask="\\d\\d"), @Validate(field="parish", required=true, minlength=3, maxlength=3, mask="\\d\\d\\d"), @Validate(field="holding", required=true, minlength=4, maxlength=4, mask="\\d\\d\\d\\d") }) However this would been fine if the actual values it is validation are not present, but they are present within the html and when debugging the bean. Why would the stripes:link trigger this? If I change it to an stripes:submit then it is fine. thanks, Dave

• NHibernate Linq queries not returning data saved in the same transaction

  - by Andrew

  Hi, I have a situation where I am using NHibernate in a WCF service and using a TransactionScope for the transaction management. NHibernate enlists in the ambient transaction fine, but, any changes I make and save inside the transaction, are not visible to any queries I make while still in that transaction. So if I add an entity and session.save() it, then further on in the code, there is a linq query against that entities table, the entity I just added is not returned. Strangely this seems to work fine if I use explicit NHibernate transactions in my tests. Anyone have any ideas as to why and what I can do about it? Many thanks Andrew

• What can I do about a SQL Server ghost FK constraint?

  - by rcook8601

  I'm having some trouble with a SQL Server 2005 database that seems like it's keeping a ghost constraint around. I've got a script that drops the constraint in question, does some work, and then re-adds the same constraint. Normally, it works fine. Now, however, it can't re-add the constraint because the database says that it already exists, even though the drop worked fine! Here are the queries I'm working with: alter table individual drop constraint INDIVIDUAL_EMP_FK ALTER TABLE INDIVIDUAL ADD CONSTRAINT INDIVIDUAL_EMP_FK FOREIGN KEY (EMPLOYEE_ID) REFERENCES EMPLOYEE After the constraint is dropped, I've made sure that the object really is gone by using the following queries: select object_id('INDIVIDUAL_EMP_FK') select * from sys.foreign_keys where name like 'individual%' Both return no results (or null), but when I try to add the query again, I get: The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "INDIVIDUAL_EMP_FK". Trying to drop it gets me a message that it doesn't exist. Any ideas?

• SDL_ttf and Numbers (int)

  - by jack moore

  int score = 0; char* fixedscore=(char*)score; . . . imgTxt = TTF_RenderText_Solid( font, fixedscore, fColor ); ^^ This doesn't work - looks like fixedscore is empty or doesn't exists. int score = 0; char* fixedscore=(char*)score; . . . imgTxt = TTF_RenderText_Solid( font, "Works fine", fColor ); ^^ Works fine, but... I guess converting int to char* doesn't really work. So how do you print scores in SDL? Oh and one more thing: why is the text so ugly? Any help would be appreciated. Thanks.

• AVAudioRecorder prepareToRecord works, but record fails

  - by iPadDeveloper2011

  I just built and tested a basic AVAudioRecorder/AVAudioPlayer sound recorder and player. Eventually I got this working on the device, as well as the simulator. My player/recorder code is in a single UIView subclass. Unfortunately, when I copy the class into my main project, it no longer works (on the device--the simulator is fine). prepareToRecord is working fine, but record isn't. Here is some code: audioRecorder = [[ AVAudioRecorder alloc] initWithURL:url settings:recordSettings error:&error]; if ([audioRecorder prepareToRecord]){ audioRecorder.meteringEnabled = YES; if(![audioRecorder record])NSLog(@"recording failed!"); }else { int errorCode = CFSwapInt32HostToBig ([error code]); NSLog(@"preparedToRecord=NO Error: %@ [%4.4s])" , [error localizedDescription], (char*)&errorCode); ... I get "recording failed". Anyone have any ideas why this is happening?

• HTML5 offline video caching in mobile safari

  - by jj

  Sorry if this gets posted twice, but Safari crashed while posting the first version, and I don't see it in my profile. Anyway I can't seem to get Safari on the iPhone or iPad to offline cache videos. Everything else gets cached just fine when I go offline. The video file is obviously in the manifest, but I just get the broken arrow. Works fine in Safari desktop. Any clues? I've tried both object embed and the video tags.

• how to automatically accept license with mounting mac osx .dmg files from command line?

  - by Vitaly Kushner

  Im automating my mac installation using 'puppet'. as a part of it I need to install several programs that come in a .dmg format. I use the following to mount them: sudo /usr/bin/hdiutil mount -plist -nobrowse -readonly -quiet -mountrandom /tmp Program.dmg The problem is that some .dmg files come with a license attached, and so script is stuck accepting the license. (there is no stdin/out when running with puppet, so I can't manually approve it to continue). Is there a way to pre-approve or force-approve the license?

• Image Magick and Ghostscript

  - by user114671

  I mainly do web design but I host a few client sites on a Centos 5 VPS. A new client has asked me to host their site and I've been given the following configuration requirement: Apache 2.2.3 PHP 5.2.17 MySQL 5.0.77 Image Magick 6.5.1-0 (not as an Apache module) Ghostscript 8.7 Checking php_info() I have: Apache 2.2.3 PHP 5.2.14 MySQL 5.0.90 I don't have IM or GS listed. I expect that my versions of PHP and MySQL are similar enough to work, but how do I get my server set up to work with this client's site as well?

• Internet Explorer 9 auto "feeling lucky" for gmail bing search

  - by Gareth Jones

  When Im at school and using school computers, i have to use has IE9. When I want to access my gmail, I type in "gmail" in the URL bar, and thus IE9 does a bing search. The page half loads (As in, loads just about every thing but the search results) and then opens my gmail, kinda like google's "i'm feeling lucky". My question is this: Why? IE9 doesn't have the URL of gmail, as i can watch the bing search load, and then the url changes to gmail, and it only happens for Gmail, having tired with searching Google and Facebook in the same method. The computer is running Windows 7 with Windows Aero disabled, and limited account privileges. While its a cool thing, I would like to known what causes it to happen. Thanks

• Using custom scrollbar on jquery lightbox

  - by Bhupi

  Hi, I need to use a custom scrollbar on jquery lightbox. My requirement is that when user clicks on a link then a popup appears and the popup contains 2 or 3 tabs, user can click on any tab to see it's content. In one of those tabs I need scrollbar to show huge content but the scrollbar should not be default it should be custom with any color. Currently I am using "JQuery's JScrollPane" plugin http://jscrollpane.kelvinluck.com to achieve the functionality, but this is not working on IE 6,7 and 8, mean scrollbar does not appear on IE. It works fine on Firefox and Chrome. Note: the same plugin works fine on IE also when I use it on page's element which is available while page load but not while the element is shown dynamically on lightbox. Thanks

• Timer in a Windows service - not really working?

  - by marc_s

  I have a Windows NT Service in C# which basically wakes up every x seconds, checks to see if any mail notifications need to be sent out, and then goes back to sleep. It looks something like this (the Timer class is from the System.Threading namespace): public partial class MyService : ServiceBase { private Timer _timer; private int _timeIntervalBetweenRuns = 10000; public MyService() { InitializeComponent(); } protected override void OnStart(string[] args) { // when NT Service starts - create timer to wake up every 10 seconds _timer = new Timer(OnTimer, null, _timeIntervalBetweenRuns, Timeout.Infinite); } protected override void OnStop() { // on stop - stop timer by freeing it _timer = null; } private void OnTimer(object state) { // when the timer fires, e.g. when 10 seconds are over // stop the timer from firing again by freeing it _timer = null; // check for mail and sent out notifications, if required - works just fine MailHandler handler = new MailHandler(); handler.CheckAndSendMail(); // once done, re-enable the timer by creating it from scratch _timer = new Timer(OnTimer, null, _timeIntervalBetweenRuns, _timeIntervalBetweenRuns); } } Sending the mail and all works just fine, and the service also wakes up every 10 seconds (in reality, this is a setting from a config file - simplified for this example). However, at times, the service seems to wake up too quickly.... 2010-04-09 22:50:16.390 2010-04-09 22:50:26.460 2010-04-09 22:50:36.483 2010-04-09 22:50:46.500 2010-04-09 22:50:46.537 ** why again after just 37 milliseconds...... ?? 2010-04-09 22:50:56.507 Works fine to 22:50:45.500 - why does it log another entry just 37 milliseconds later?? Here, it seems it's totally out of whack.... seems to wake up twice or even three times every time 10 seconds are over.... 2010-04-09 22:51:16.527 2010-04-09 22:51:26.537 2010-04-09 22:51:26.537 2010-04-09 22:51:36.543 2010-04-09 22:51:36.543 2010-04-09 22:51:46.553 2010-04-09 22:51:46.553 2010-04-09 22:51:56.577 2010-04-09 22:51:56.577 2010-04-09 22:52:06.590 2010-04-09 22:52:06.590 2010-04-09 22:52:06.600 2010-04-09 22:52:06.600 Any ideas why?? It's not a huge problem, but I'm concerned it might start to put too much load on the server, if the interval I configure (10 seconds, 30 seconds - whatever) seems to be ignored more and more, the longer the service runs. Have I missed something very fundamental in my service code?? Am I ending up with multiple timers, or something?? I can't seem to really figure it out..... have I picked the wrong timer (System.Threading.Timer) ? There's at least 3 Timer classes in .NET - why?? :-)

• Using Excel To Read Access Without MS Access On Computer

  - by Tom Clark

  I have written code that joins two table in access, using criteria supplied from drop down lists in excel and then returns the data to a specific location on the spreadsheet (titles already on the sheet). This works fine on my box and others with MS Access on the machine, but the purpose of writing this was to give people (associates) that dont have the MS Access on their machines (which is most of them) to be able to do simple queries to the database. When we try to run this on a machine without MS Access, we are getting the error message "Compile Error: Cant find project or library." Since this works fine on any machine so far that has Access, but not the others I am wondering if this is not possible without the actual Access software. Any help or insight would be appreciated.

• Is DevCon.exe still the best way to restart/power cycle USB ports after resuming from hibernation in

  - by ProfessionalAmateur

  I have a USB broadband card on my Windows 7 laptop. It loathes resuming from hibernation properly. Back in the XP days I would issue a call devcon.exe from the command prompt and restart the selected ports (Saves you having to manually unplug and plug back in your USB devices). Ive been trying this is Windows 7, but the UAC keeps getting in the way. I'll start a command prompt. Issue the devcon command, but UAC asks me if I really want to do this, when I click yes it opens a different command prompt and launches the command. After the command completed this new prompt window closes faster than the speed of light and I cannot see the results. So Im thinking there has to be a better way to do this in the Vista/Win7 world...?

• Android bluetooth socket error

  - by ashwini

  I am using backport bluetooth api on android 1.6. I am using Google Bluetooth Chat sample app for testing. The app works fine in normal scenarios. In a scenario, when I try to connect to paired device which is in off state, I get following error. 01-04 09:00:11.629: ERROR/BluetoothEventLoop.cpp(84): onGetRemoteServiceChannelResult: D-Bus error: org.bluez.Error.ConnectionAttemptFailed (Host is down) 01-04 09:00:11.729: DEBUG/dalvikvm(128): GC freed 4535 objects / 256008 bytes in 296ms 01-04 09:00:21.880: ERROR/bluetooth_RfcommSocket.cpp(1433): connect error: Host is down (112) But it sets the state as connected. The app is unable to catch the exception. Why does it happen? Or is it the case with backport api? Any help is appreciated as I am struggling a lot to get things run fine.

• How to position a div at the bottom of the viewport in standard and in quirks mode ??

  - by Gonzalo

  Hi, I need to position a div to the bottom of my viewport. I start using position:fixed; bottom:0px; and that work just fine. But the thing that I'm working on gets injected via javascript in different pages. And some of the pages doesn't have a doctype defined, so in IE gets rendered like quircks mode, so the div doesn't get positioned correctly.. I've tried to position the div using javascript (document.documentElement.clientHeight) and that works fine. But when no doctype is defined, the "document.documentElement.clientHeight" is 0, so again the div doesn't get positioned correctly. Any idea on how to fix this problem? I'm only interested in IE 7 and 8. Thanks in advance Gonzalo
