  • Interface Builder "Simulate Interface" not working

    - by bpapa
    I am using Interface Builder to play around with some ideas. I never noticed that there is a "Simulate Interface" feature which apparently will render the nib in the iPhone simulator. So, I created a view, put one component in there (a Segmented Control), saved it, selected "Simulate Interface", the simulator launched but... nothing rendered in the simulator. Just a black screen. I thought maybe my nib wasn't complete enough, so I've tried it with all of my old nibs and I'm having the same problem with all of them. None of them render in the simulator at all. Is there some trick that I'm missing?

  • data directory in automake

    - by Alex Farber
    I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only. How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.

  • Handling dynamic data from javascript or rails

    - by 99miles
    I have page consisting of a calendar view ( http://code.google.com/p/calendardateselect/ ) as well as divs, each of which contain information about a person. In each div I want to have a link to a new controller and action, and pass the id for the person and the date selected in the calendar. I can think of a one way, but I'm thinking there's likely a better solution: 1) Do something like: =link_to_function "Week", "weekClicked(#{person.id})" Then in the weekClicked() javascript method I get the selected date from the calendar, such as: $('e_date').selected_date; then with javascript I could make a post request as mentioned here: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit 2) Or, is there a way that I could make each link a button in it's own form and maybe have a hidden field that gets the selected date from the calendar as or before the form is submitted? I tried this too, but couldn't figure it out. This definitely seems like it's more on the right track than #1. Thanks.

  • Call Ruby class over java with jruby

    - by r2
    Hi all If I implement a class in ruby and compile it with jrubyc than it is not possible to call it from a java class directly if I start it with java. If I see this right I have to use org.jruby.embed... to implement a wrapper wich takes a class name and a metod to call my ruby class. Do I have to do this also if I start the application with jruby? In my current project I start java workflow engine completely with jruby. The workflow has to call a method in a ruby class which he cant find. Maybe easier to understand: [ruby_class] <-----has to call----. | jruby [ruby_start_script] --starts--> [java wfe]

  • Is Valid IMAGE_DOS_SIGNATURE

    - by iira
    I want to check a file has a valid IMAGE_DOS_SIGNATURE (MZ) function isMZ(FileName : String) : boolean; var Signature: Word; fexe: TFileStream; begin result:=false; try fexe := TFileStream.Create(FileName, fmOpenRead or fmShareDenyNone); fexe.ReadBuffer(Signature, SizeOf(Signature)); if Signature = $5A4D { 'MZ' } then result:=true; finally fexe.free; end; end; I know I can use some code in Windows unit to check the IMAGE_DOS_SIGNATURE. The problem is I want the fastest way to check IMAGE_DOS_SIGNATURE (for a big file). I need your some suggestion about my code or maybe a new code? Thanks

    - by john
    im developing a web application, using multiple pages, each with their own controller. The problem now is that there are some variables in a controller, created for one page, that are required for an other page ( with a different controller).

  • Most Lite-Weight XML Parser with XPath and Wide-char Support

    - by Mystagogue
    I want a lite-weight C++ XML parser/DOM that: Can take UTF-8 as input, and parse into UTF-16. Maybe it does this directly (ideal!), or perhaps it provides a hook for the conversion (such as taking a custom stream object that does the conversion before parsing). Offers some XPath support. I've been looking at RapidXML, the Kranf xmlParser, and pugiXML. The first two of those might permit requirement #1 by way of a hook. The third, pugiXML, supports the #2 requirement. But none of those three fulfill both requirements. What is the smallest (free) library that can handle both requirements?

  • Monitoring folders for changes

    - by blcArmadillo
    I'm working on a project that will require an application that watches a list of directories the user specifies for changes. Also, I'd like to give the users the option of running the application as a service or on an individual basis. Since users can choose to run it on an individual basis I don't think listening for some operating system event triggered by the addition or deletion of files (if such events exist) would be sufficient. I thought about maybe calculating a checksum for the deepest folder and then building up. I could then compare these checksums on subsequent scans to try and pinpoint where the changes have occurred. Would that be an appropriate solution; if not what would be the best way of doing this in an efficient manner? Also, I'm not quite sure what to tag this as so if you have any recommendations let me know and I'll as them as I see fit. EDIT: I'll need this method to work on Windows, OS X, and ideally Linux

  • How can I set the minDate/maxDate for jQueryUI Datepicker using a string?

    - by leo
    jQueryUI Datepicker documentation states that the minDate option can be set using "a string in the current dateFormat". So I've tried the following to initialize datepickers: $("input.date").datepicker({ minDate: "01/01/2010", maxDate: "12/31/2010" }); However, this results in my datepicker having a selectable date range that goes from 11/06/2015 to 12/17/2015. I've checked the current dateformat and its mm/dd/yy, which is supposed to mean 2 digits for the month, 2 for the day, and 4 for the year, separated by slashes. I've also tried including dateFormat: "mm/dd/yy" in the inizialization statement. I've also checked the values for minDate and maxDate afterwards and they ARE being set to the values I want: 01/01/2010 and 12/31/2010. I want to be able to set min/maxDate with strings because I'm being passed these values as strings from somewhere else. Maybe someone knows why this happens and how to solve this, or a workaround to achieve this, perphaps changing the format of the date strings or something? Thanks EDIT: Using: jQuery v1.3.2 and jQuery UI v1.7.2

  • Has anyone ever encountered a Monad Transformer in the wild?

    - by martingw
    In my area of business - back office IT for a financial institution - it is very common for a software component to carry a global configuration around, to log it's progress, to have some kind of error handling / computation short circuit... Things that can be modelled nicely by Reader-, Writer-, Maybe-monads and the like in Haskell and composed together with monad transformers. But there seem to some drawbacks: The concept behind monad transformers is quite tricky and hard to understand, monad transformers lead to very complex type signatures, and they inflict some performance penalty. So I'm wondering: Are monad transformers best practice when dealing with those common tasks mentioned above?

  • Is removing unused functionality a bad thing?

    - by Andrew Grimm
    Is it possible for YAGNI to apply in the past tense? You created some functionality, it was used a little bit a while ago, but you aren't using it any more, and you don't want to maintain it, so you'd rather delete it. Is getting rid of unused or rarely-used functionality neccessarily a bad thing? Background: I use source control, so if I need the functionality again, I can get it. I'm the only user of my software (I'm a bioinformatician analyzing a data set). One scenario where I came across this was that I was using inheritance, with a parent class, and two child classes. One was handling files generated by 454 sequencing (next-generation sequencing), and the other was handling files generated by Sanger sequencing (previous-generation sequencing). I was actively maintaining the latter, but not the former. Maybe my mistake was using inheritance rather than composition, but that's a slightly different story.

  • Handle mysql restart in SQLAlchemy

    - by wRAR
    My Pylons app uses local MySQL server via SQLAlchemy and python-MySQLdb. When the server is restarted, open pooled connections are apparently closed, but the application doesn't know about this and apparently when it tries to use such connection it receives "MySQL server has gone away": File '/usr/lib/pymodules/python2.6/sqlalchemy/engine/default.py', line 277 in do_execute cursor.execute(statement, parameters) File '/usr/lib/pymodules/python2.6/MySQLdb/cursors.py', line 166 in execute self.errorhandler(self, exc, value) File '/usr/lib/pymodules/python2.6/MySQLdb/connections.py', line 35 in defaulterrorhandler raise errorclass, errorvalue OperationalError: (OperationalError) (2006, 'MySQL server has gone away') This exception is not caught anywhere so it bubbles up to the user. If I should handle this exception somewhere in my code, please show the place for such code in a Pylons WSGI app. Or maybe there is a solution in SA itself?

  • Problem with setContentBorderThickness:forEdge: not actually setting the value

    - by jxpx777
    I'm trying to use setContentBorderThickness:forEdge: to create a bottom bar in a Cocoa application. mipadi was on to something, but in testing it out, I think maybe this is a slightly different problem: -(void) adjustContentBorderBasedOnArrayControllerSelection{ if(([[self.resultsArrayController selectionIndexes] count] == 0)){ [[self window] setContentBorderThickness:40.0f forEdge:CGRectMinYEdge]; NSLog(@"%f", [[self window] contentBorderThicknessForEdge:CGRectMinYEdge]); } else { [[self window] setContentBorderThickness:60.0f forEdge:CGRectMinYEdge]; NSLog(@"%f", [[self window] contentBorderThicknessForEdge:CGRectMinYEdge]); } } Both of those NSLog() messages show the thickness value is 0.0 even after I explicitly set it. Anyone know what's up with that?

  • ASP.NET MVC: What's the difference in concept between Service and Repository

    - by Richard77
    Hello, The question I'm asking is kind of subjective. I've seen twice, while exercising with real projects such as StoreFront, both Repository and Services. Sometimes they can just be folders or projects attached to the solution. But they contain classes and interfaces. So, I'd like to know what goes to the repository and what goes to the services. So far, I was familiar with repositories (we put methods and properties in the repository to reduce the complexity in the controller). How about the services? So, ASP.NET MVC: What's the difference in concept between Service and Repository? (Maybe none) My question is Kind of subjective, but I'd like to make sure that I'm not missing anything. Thanks for helping

  • [Alfresco] property qualified-name in method getContentReader

    - by Ar3s
    Hi there, I first apologize for my poor english level and maybe for the stupidity of my question ;) I am on an alfresco project to learn how it works. I have to browse programatically my content repository and gather datas all along. In order to do that I guessed I had to use a ContentReader (I get from my ContentService) but the method getReader wants a nodeRef and a propertyQualifiedName. I am ok with the nodeRef, I get what it's needed for. But the propertyQualifiedName puzzles me, I barely get what it is but I frankly don't get how it is used. Reading some alfresco forum threads I get more and more scared that I dont even get how a reader works, I somewhere saw that a reader can read only one node and only one time per instance. If anyone knows a bit about the Java API for Alfresco Content Repository use I am all hears ! Cheers all !

  • Windows Azure Queues, WCF, MSMQ integration

    - by user104295
    Hi there, I have a scenario where I need a desktop console app to communicate with a Windows Azure Queue... the most important thing is that the message is received by the server eventually. Also, the desktop app may be disconnected from the Internet sometimes. In the traditional WCF+MSMQ approach you'd be able to send a message which would be cached in MSMQ until MSMQ could reach the Server's MSMQ and send the message. What's the equivalent when Windows Azure is the server-side? Is it possible for the same approach to be used, where MSMQ just communicates with a Windows Azure Queue rather than an MSMQ on a Windows Server? Maybe Windows Azure Queue is the wrong approach? I have heard about something called message buffer, but don't know what this is (yet!). thanks for your help Kris

  • From interpeted to native code: "dynamic" languages compiler support

    - by Daniel
    First, I am aware that dynamic languages is a term used mainly by a vendor; I am using it just to have a container word to include languages like Perl (a favorite of mine), Python, Tcl, Ruby, PHP and so on. They are interpreted but I am interested here to refer to languages featuring strong capability to support the programmer efficiency and the support for typical constructs of modern interpreted languages My question is: there are dynamic languages can be compiled efficiently in native executable code - typically for Windows platforms? Which ones? Maybe using some third part ad-hoc tools? I am not talking about huge executables carrying with them a full interpreter or some similar tricks nor some smart module able to include its own dependances or some required modules, but a honest, straight, standard, solid executable code. If not, there is some technical reason inhibiting the availability of such a best-of-both-world feature? Thanks! Daniel

  • How to update individual files in a war file

    - by ziggy
    Hi guys, I am doing some research in the way i can deploy an application efficiently using a war file. What i currently do is i deliver the war file everytime there is a release. This means everytime there is a change no matter how small the change is i have to build and deliver all files that make up the application. I am thinking that maybe this is not the correct way to do this. For example if there is a change to a css file i have to rebuild the war file which will include all file. This includes recompiling all *.java files as well. In the above example, is it possible to build a war file with just the css file and deploy it to the tomcat server and have Tomcat just replace the css file and leave everything else as is?

  • Resizing an Binarized image in C#

    - by mouthpiec
    Hi, I have the following code to resize a Binarized image (hence pixel value is 0[black] or 255[white]) with the following code Bitmap ResizedCharImage = new Bitmap(newwidth, newheight); using (Graphics g = Graphics.FromImage((Image)ResizedCharImage)) { g.CompositingQuality = CompositingQuality.HighQuality; g.InterpolationMode = InterpolationMode.HighQualityBilinear; g.SmoothingMode = SmoothingMode.HighQuality; g.PixelOffsetMode = PixelOffsetMode.HighQuality; g.DrawImage(CharBitmap, new Rectangle(0, 0, newwidth, newheight), new Rectangle(0, 0, CharBitmap.Width, CharBitmap.Height), GraphicsUnit.Pixel); } The problem that I am having is that when resizing (i am enlarging the image) some of the pixel values become 254, 253, 1, 2 etc. I need that this do not occur. Is this possible, maybe by changing one of the Graphins properties?

  • How to combine two sql queries?

    - by plasmuska
    Hi Guys, I have a stock table and I would like to create a report that will show how often were items ordered. "stock" table: item_id | pcs | operation apples | 100 | order oranges | 50 | order apples | -100 | delivery pears | 100 | order oranges | -40 | delivery apples | 50 | order apples | 50 | delivery Basically I need to join these two queries together. A query which prints stock balances: SELECT stock.item_id, Sum(stock.pcs) AS stock_balance FROM stock GROUP BY stock.item_id; A query which prints sales statistics SELECT stock.item_id, Sum(stock.pcs) AS pcs_ordered, Count(stock.item_id) AS number_of_orders FROM stock GROUP BY stock.item_id, stock.operation HAVING stock.operation="order"; I think that some sort of JOIN would do the job but I have no idea how to glue queries together. Desired output: item_id | stock_balance | pcs_ordered | number_of_orders apples | 0 | 150 | 2 oranges | 10 | 50 | 1 pears | 100 | 100 | 1 This is just example. Maybe, I will need to add more conditions because there is more columns. Is there a universal technique of combining multiple queries together?

  • Reference platform specific System.Data.SQLite

    - by Dmitriy Nagirnyak
    I am using SQLite for the unit testing and might use it as a database for local development/staging. The System.Data.SQLite has basically 2 versions: x86 and x64. Correct one should be used for the specific platform. I have 64 bit Win7, other guys in the team might use 32-bit OSs. The server's platform is not known at this stage. If I use 32-bit version of the assembly on 64-bit platform I get BadImageFormatException: Could not load file or assembly 'System.Data.SQLite'. I believe similar will happen trying to use 64-bit assembly on 32-bit platform. So my question is what is the best way to reference the SQLite assembly so that it does not depend on the platform and people can just use it? It is ok to use 32-bit version of assembly on a 64-bit platform (Maybe there is a switch for that somewhere?).

  • Database query optimization

    - by hdx
    Ok my Giant friends once again I seek a little space in your shoulders :P Here is the issue, I have a python script that is fixing some database issues but it is taking way too long, the main update statement is this: cursor.execute("UPDATE jiveuser SET username = '%s' WHERE userid = %d" % (newName,userId)) That is getting called about 9500 times with different newName and userid pairs... Any suggestions on how to speed up the process? Maybe somehow a way where I can do all updates with just one query? Any help will be much appreciated! PS: Postgres is the db being used.

  • layout messed up once spinner has entries

    - by AndyAndroid
    Hello, I have <LinearLayout android:id="@+id/LinearLayoutPlayer" xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Spinner android:id="@+id/Spinner01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="100"></Spinner> <ToggleButton android:text="@+id/ToggleButton01" android:id="@+id/ToggleButton01" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_weight="1"></ToggleButton> </LinearLayout> Which displays a spinner and next to it a toggle button. Everything okay so far. Of course the spinner need some entries, so I add to the spinner the attribute: android:entries="@array/myentries" The problem now is that the toggle button is a bit lower than the spinner and the botton of the toggle button is cut off, maybe 3 or 5 lines of pixels. Anyone an idea what is wrong here? Android is version 2.2 Thanks!
