• Visual Studio 2008 error while debugging an app with "uiAccess=true" in the manifest

  - by Jon Tackabury

  I have a C# WinForms application that has "uiAccess" set to "True" in it's manifest file. When I try to start/debug it in Visual Studio 2008 SP1 under Windows 7 x64 (RTM) I get this error: Running an Accessibility application requires following the steps described in Help. The help button is a broken link, and clicking ok just closes the application. It is digitally signed, and I can start it just fine in Windows Explorer. Here is the same bug in MS Connect, but unfortunately it's closed: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=384183 Question: Can anyone else using Vista/Win7 x64 (with UAC enabled) confirm that they experience the same problem? Has anyone seen this problem before and have any idea how to work around it?

• Load only some columns with Hibernate native SQL queries

  - by Alessandro Dionisi

  I have a table on the database and I want to load only some columns from the result set. I defined a native sql query in the hbm file: <sql-query name="query"> <return alias="r" class="RawData"/> <![CDATA[ SELECT DESCRIPTION as {r.description} FROM RAWD_RAWDATAS r WHERE r.RAWDATA_ID=? ]]> </sql-query> This query however fails with error: could not read column value from result set: RAWDATA1_14_0_; Invalid column name SQL Error: 17006, SQLState: null, because Hibernate tries to load all fields from the result set. I found also a bug in Hibernate JIRA (http://opensource.atlassian.com/projects/hibernate/browse/HHH-3035). Anyone knows how to accomplish this task with a workaround?

• Setting a background drawable for a dialog?

  - by user291701

  Hi, Tried posting this at android dev, wanted to go here too in case anyone knows. I'm trying to supply a custom background drawable for a dialog. I've created the following in my styles.xml file: <style name="CustomDlg" parent="@android:style/Theme.Dialog"> <item name="android:windowBackground">@drawable/my_background</item> </style> This works fine on 1.6+. On my g1 running 1.5 (and the 1.5 emulator) the drawable is used, but the area around the dialog is opaque black instead of being translucent. Is there something I'm missing here, or is this a bug with 1.5? Any work arounds? Is 1.5 just the ie6 of Android? Thanks

• C# == operator in Immediate window behaves differently than at run-time

  - by Damiano

  Try the following in the Immediate window: object a1 = "a"; object a2 = "a"; a1==a2 // outputs false and you'll see that a1 == a2 outputs false. However, at runtime in either a window app or console, you'll get true: object t1 = "a"; object t2 = "a"; MessageBox.Show((t1 == t2).ToString()); // outputs true The runtime behavior is consistent with the definition for the == operator and strings. Does anybody know if this a bug in the Immediate window?

• Is there a good web-based project management app with scheduling?

  - by Andykiteman

  Ideally something as intuitive as basecamp, with good usability and accessibility. The best I've seen is huddle.net but it's still weak in several areas. Must have: Projects - ability to add people & tasks and schedule tasks to people Calendar - showing when people are busy or available Role based access - Admins and non-admins History - ability to look back at all history Anyone seen a product that's worth a look? Clarification: Must be hosted i.e. not require my own hardware or IT staff I'm looking for an app to schedule people with specific tasks at specific times and monitor the outcomes. I'm already using Mingle (for stories), Basecamp (to run the business) and Exceptional (to track bugs). I'm not looking for a bug-tracking system or a story management application (I already looked at VersionOne, but chose Mingle due to it's nicer UI) My response to the answer being auto-selected: I still don't feel the answer (chosen for me) is the correct one. It's a useful list but little more, and doesn't provide the solution I was seeking.

• Can I prevent a computed column from changing it's value if the formula changes?

  - by William Hurst

  I have a computed column in MS SQL 2005 that does some VAT calculations. The website uses invoices that can only be generated once and rely on the value in the computed column to work out the VAT. Unfortunately, a bug was found that means that the the VAT value calculated was off by a few cents. Not a huge problem but we can't change the values from all the previously computed values as these need to be honoured on the invoices. tldr; How do I change the calculation for a computed column without re-calculating the values that have already be calculated?

• Extended maxima transform in Matlab

  - by garvin

  I use imtophat to apply a filter to an m x n array. I then find the local max using imextendedmax(). I get mostly 0's everywhere except for 1's in the general areas where I am expecting a local max. The weird thing is, though, that I don't get just one local max. Instead in these places I get MANY elements with 1's such as 00011100000 00111111000 00000110000 yet the values there are close but NOT equal so I would expect that there would be one that is higher than all of the rest. So I'm wondering a) if this is a bug and how I might fix it and b) how you would choose choose the element of these 1's with the highest value.

• Does window.open not work inside an AIR html component?

  - by John Isaacks

  I have a component in AIR like so: <mx:HTML id="html" width="100%" height="100%" location="https://example.com" locationChange="dispatchLocationChange(event)" /> The page it loads contains this: <a onclick="alert('onclick')">Alert</a> <a href="javascript:alert('js')">Alert</a> <a onclick="window.open('http://www.google.com','_blank')">new window</a> The 2 alerts both work. however nothing happens when you click the new window link. all 3 links works when in a real browser so I know its ok. Is there just no support for window.open in the AIR HTML component? or is this a bug? Is there a work around?

• How do you handle multiple (overlapping) projects in trac?

  - by Oliver Giesen

  We are using trac and are really satisfied with it. However, out of the box, trac is best suited for single-project environments only. I'd be interested to hear about the various approaches people take to make it work with multiple projects nevertheless and their experiences with them. Are there any plugins to recommend? Any patches, tweaks or whatnots? Are you maybe even using an entirely different bug-tracking system that offers all of trac's functionality plus multi-project support? We recently started managing a second project ourselves which generally works okay but also has some drawbacks, especially where the two projects overlap because of common library code we wrote that is used in both projects. How do you handle this? (I'll attach our own current approach as an answer to this post.)

• Using a part of a class in multiple projects

  - by Axarydax

  I have a set of methods that do some utility work over SQL connection, and until now these have been copied over from project to project. But as time goes on, project numbers have grown and I need to keep these methods in sync in case I find a bug or need to update it. I have managed to get it to the state that SQL access class is a partial class, one part is specific for project and contains wrappers for a specific database. The second part is the common one and contains methods that are used in all project-specific databases. The problem is that now I would have the "utility" class copied over 8 projects, with the same content, but in different namespaces. In C/C++ it would have been simple, because I would just have #included the contents of the file wherever needed. What should I do in C#?

• Fetch a Rails ActiveRecord 'datetime' attribute as a DateTime object.

  - by Tobias Cohen

  I have an attribute in one of my models that contains a Date/Time value, and is declared using t.datetime :ended_on in my migrations. When I fetch this value using myevent.ended_on, I get a Time object. The problem is that when I try to use this attribute as an axis in a Flotilla chart, it doesn't work properly because Flotilla only recognizes dates as Date or DateTime objects. I thought about writing a virtual attribute that will convert the existing Time value to a DateTime, but I'm wary of doing this, since I've heard that Time can't handle dates later than 2040, and I don't wish to risk creating a "2040 bug" to worry about later. Is there any way I can persuade ActiveRecord to return DateTime objects for this attribute instead of Time objects?

• Should I send patch against 2-3-stable or master

  - by Nadal

  I am trying to find a way to contribute back to rails. I was thinking I should validate if this patch https://rails.lighthouseapp.com/projects/8994/tickets/4154-expires_now-broken works or not. I was able to validate the problem. The problem still exists in 2.3.5 and in 2-3-stable branch of rails. I was not able to apply his patch at 2-3-stable branch of rails . Also the patch failed for master branch. Looked at the diff and manually changed the code and the new code solves the bug. Now if I want to attach my patch to the ticket should I create my patch against 2-3-stable branch or master branch? I believe master is more closely aligned with rails3 changes.

• Comparison question string vs int

  - by Mike

  Can someone explain to me why these comparisons work they way the do. I had a bug in one of my scripts that took me a little bit to work through. I was using read-host and typing a number. It was storing it as a string. Write-Host "(`'2`' -gt 9 ) = " ('2' -gt 9 ) Write-Host "(2 -gt 9 ) = " (2 -gt 9 ) Write-Host "(`'2`' -gt 10 ) = " ('2' -gt 10 ) If you are comparing a string to an Int does it use the Ascii value? If so why does the first one show $false, it should be $true. Then how is it when you chage it to an int of 10 it because $true.

• Linux program - reverse highlighted text

  - by Oren

  I want to develop a program that will run on the background of my Ubuntu 12.04 so when some text is selected in some textbox of any running program and some key-combination is pressed (like ctrl-F12), the text will be cut, reversed, and pasted in the same place. I know some programs that do it on windows. It is useful in some programs and web-pages that do not support right-to-left languages like arabic and hebrew - the letters are printed from left to right so the text becomes reversed. More specifically I need it in Prezi that has this kind of bug in their embedded flash editor (I thought about writing a chrome-plugin, but I don't think such plugin can manipulate the selected text inside a flash objects). Do you know if such a program exist? Where should I start reading in order to develop a program with such capabilities (manipulate selected text in other programs)? Thanks

• QR Factorization Discrepancy

  - by KyleSum

  I'm trying to get a feel for the Intel MKL library with a simple back-solve (A*x = b) using a QR factorization and comparing my MKL answer to the answer of a known working solution. When my answers didn't come up correct I printed a diff between the Q and R matrices of the known working and the MKL test code. I know MKL/lapack uses "elementary reflectors" to store the values of both the Q and R matrices. So, I'm wondering if these differences (mostly +/-) are by design or the result of some bug. I'm using DGEQRF, DORMQR, and DTRSM routines to solve the system and DORGQR (for debugging) to get the Q matrix shown in the diff. diff with 6x6 matrix (top known, bottom mkl): http://pastebin.com/4uwcME0J

• Maven: Variables are not replaced in installed and deployed POM

  - by mmuthu

  We have been trying to migrate our multi-module projects to maven. I have been struggling with the maven install plugin bug "http://jira.codehaus.org/browse/MNG-2971". I have written a Java program which can find and replace the expressions using my settings.xml and POM in my local repository view. As a result all of my parent POM's are having a additional phase in the build process. What i'm doing is that i have attached a goal which will run my Java program during "validate" phase. I think this is a not a good idea instead i would have asked individuals to run the program on their local repository on their own. What i'm asking here is that the best way to work around the "install" plugin issue (MNG-2971). I searched through the net but i could not locate such work around.

• RelayCommands overriding the "IsEnabled" of my buttons.

  - by vidalsasoon

  RelayCommands overriding the "IsEnabled" of my buttons. Is this is a bug? Here is xaml from my View and code from my ViewModel <Button Grid.Column="0" Content="Clear" IsEnabled="False" cmd:ButtonBaseExtensions.Command="{Binding ClearCommand}" /> public RelayCommand ClearCommand { get { return new RelayCommand(() => MessageBox.Show("Clear Command")); } } Notice I hardcoded the IsEnabled="False" in my xaml. This value is completely ignored (button always enabled). I realize that RelayCommand have a CanExecute overload but I did want to use this as I want to do more than just have a disabled button.

• Alternatives to FastDateFormat for efficient date parsing?

  - by Tom Tucker

  Well aware of performance and thread issues with SimpleDateFormat, I decided to go with FastDateFormat, until I realized that FastDateFormat is for formatting only, no parsing! Is there an alternative to FastDateFormat, that is ready to use out of the box and much faster than SimpleDateFormat? I believe FastDateFormat is one of the faster ones, so anything that is about as fast would do. Just curious , any idea why FastDateFormat does not support parsing? Doesn't it seriously limit its use? Thanks! EDIT Holy crap, I just left a comment and that literally REMOVED a good answer! This appears a serious bug on stackoverflow!

• MySQL Returns wrong values on SELECT statement

  - by Andrew K

  All, I'm wondering if this is a MySQL bug, but since I've seen others playing with larger numbers than this, I'm thinking I'm doing something wrong here. Here is my table structure for the table I'm querying: mysql describe ipspace6\G ************* 1. row ************* Field: id Type: decimal(39,0) unsigned Null: NO Key: Default: NULL Extra: ************* 2. row ************* Field: addr Type: decimal(39,0) unsigned Null: NO Key: PRI Default: 0 Extra: ************* 3. row ************* Field: netmask Type: decimal(39,0) unsigned Null: NO Key: Default: 0 Extra: ************* 4. row ************* Field: subnet Type: int(4) Null: NO Key: Default: NULL Extra: Now, I run a simple SELECT statement against the "id" column: mysql SELECT id FROM ipspace6 WHERE id='50552019118453823914642686339427860480'; +----------------------------------------+ | id | +----------------------------------------+ | 50552019118453823730175245602332344320 | | 50552019118453823730175245602332344320 | | 50552019118453823914642686339427860480 | | 50552019118453823914642686339427860480 | +----------------------------------------+ ...What the heck is going on here? Two of these results are valid, and two definitely are not. It's not like I'm doing some super-complex nested query or anything, this is simple stuff, and it's driving me insane. Help, anyone?

• No optimization causes wrong search result

  - by KailZhang

  I just took over our solr/lucene stuff from my ex-colleague. But there is a weird bug. If there is no optimization after dataimport, actually if there are multiple segment files, the search result then will be wrong. We are using a customized solr searchComponent. As far as I know about lucene, optimization is only optimization which could improve the speed of indexing and should not affect search result. I doubt this may be related to multithreading or unclosed searcher/reader or something. Anybody can help? Thank you.

• php Undefined index but i can access that key anyways

  - by Linas

  I just don't get it, i know what the error means i know how to fix it but it seems to be more of a php bug, i have an array returned from some function which looks like this when i use var_dump: array(1) { ["89512480-1884-11e2-aee6-618bca23e5b1"]=> array(5) { ["created"]=> string(10) "1350514509" ["expires"]=> string(10) "1351724109" ["token"]=> string(40) "81fa1895a6d5d4cb11efae8e71adf98fbdbfb5ca" ["user_agent"]=> string(40) "6ab18a2ea1d4b17d67713e416b07d46bf2f4d03b" ["username"]=> string(4) "test" } } array(0) { } but if i try for example: echo $token['89512480-1884-11e2-aee6-618bca23e5b1']['user_agent']; it shows me the value, but at the same time i get that annoying error, what the hell?

• UIWebView Loading content properly on iOS 6 simulator but not on device?

  - by David Hegner

  I have encountered a weird bug with a released app. My UIWebView is no longer loading content on iOS 6, yet the content still displays in the simulator. The activity indicator displays properly but then it loads a blank url? Again, this only happens on a device, not on the simulator. To provide extra context (in the simulator the NSURLRequest is assigned the proper URL. When run on a device the value is nil.) Here is my code : -(void)loading { if(!self.webView.loading) [self.activityIndicator stopAnimating]; else { [self.activityIndicator startAnimating]; } } - (void)viewDidLoad { [self.webView addSubview:self.activityIndicator]; NSURLRequest *requestUrl = [NSURLRequest requestWithURL:self.url]; [self.webView loadRequest:requestUrl]; self.timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/2.0) target:self selector:@selector(loading) userInfo:nil repeats:YES]; [super viewDidLoad]; NSLog(@"%@", requestUrl); }

• Do (statically linked) DLLs use a different heap than the main program?

  - by happy_emi

  I'm new to Windows programming and I've just "lost" two hours hunting a bug which everyone seems aware of: you cannot create an object on the heap in a DLL and destroy it in another DLL (or in the main program). I'm almost sure that on Linux/Unix this is NOT the case (if it is, please say it, but I'm pretty sure I did that thousands of times without problems...). At this point I have a couple of questions: 1) Do statically linked DLLs use a different heap than the main program? 2) Is the statically linked DLL mapped in the same process space of the main program? (I'm quite sure the answer here is a big YES otherwise it wouldn't make sense passing pointers from a function in the main program to a function in a DLL). I'm talking about plain/regular DLL, not COM/ATL services EDIT: By "statically linked" I mean that I don't use LoadLibrary to load the DLL but I link with the stub library
