• WPF Custom Control with Image problem

  - by user311883

  Hi all, I am quite new to WPF/XAML and I am currently facing a problem. I have a solution with two projects in it, the first project is a Custom Control Library with a custom Window form control inside. The second project is a WPF application using my custom window form. All work fine except for the form Icon. In the WPF application project I set my window icon property to "/ProjectTwoNameSpace;component/Resources/Images/Film.ico", and in the WPF custom control I try to show that image that way : <Image Grid.Column="0" Margin="3" Width="27" Height="27"> <Image.Source> <BitmapImage UriSource="{Binding Path=Icon}" /> </Image.Source> </Image> But it doesn't work, I get a error at runtime saying that the property UriSource or StreamSource must be set for my tag. Anyone can help me ? I think it's jsut a WPF newbie problem ^^

• how change nginx temp & log folder or disable logging completely

  - by Ehsan Khodarahmi

  I'm running nginx 1.3.5 under windows seven, I need to execute nginx directly from a read-only media (CD or DVD), but when I want to run it, it fails with this error: nginx: [alert] could not open error log file: CreateFile() "logs/error.log" fail ed (5: Access is denied) 2012/08/28 13:52:46 [emerg] 5604#2864: CreateDirectory() "J:\nginx-1.3.5/temp/client_body_temp" failed (5: Access is denied) where J is my CD-ROM drive letter. I've changed nginx.conf to disable logging completely, but seems anyway it still tries to build a file named 'error.log' in '/logs' folder & some extra temporary contents in '/temp' folder at the startup, so I want to change 'logs' & 'temp' directory path to windows temp folder (%temp%), but I dont have any idea that how can I do it. Also I want to know why nginx still creates 'logs/error.log' after disableing error logging ?

• mediawiki markup equivalent of WMD editor?

  - by Justin Grant

  Anyone have a recommendation for an editor like the WMD editor, but using MediaWiki markup instead of Markdown? Our site is already using MediaWiki markup but we want a slicker editor without changing markup completely. Requirements include: live preview of formatted text underneath the markup you're typing a toolbar for common formatting (bold, italic, links, bullets, numbered-list, code, etc) keyboard shortcuts for each toolbar button (e.g. CTRL+B for bold) Undo/redo via keyboard shortcuts (CTRL+Z/CTRL+Y) or toolbar buttons works well in the usual set of popular browsers (including IE6!) open-source would be preferred

• RESTful membership

  - by FoxDemon

  I am currentlly trying to design a RESTful MembershipsController. The controller action update is used only for promoting, banning, approving,... members. To invoke the update action the URL must contain a Parameter called type with the appropriate value. I am not too sure if that is really RESTful design. Should I rather introduce sepearate actions for promoting,... members? class MembershipsController < ApplicationController def update @membership= Membership.find params[:id] if Membership.aasm_events.keys.include?(params[:type].to_sym) #[:ban, :promote,...] @membership.send("#{params[:type]}!") render :partial => 'update_membership' end end end

• at what point in the test cycle are the test results written to a file?

  - by jcollum

  I'd like to take the entirety of the test results and publish it to a database. Got the database, got the table, got the script to publish it. Question is, at what point in the ms-test cycle would the results be fully written to the file? And how can I get the path to that file? I'd especially like to grab the "TextMessages" node and put it into my database. I assumed AssemblyCleanup, but the TestContext doesn't seem to be available then.

Anyone know how I can avoid this when I export my project in eclipse?

• Where to open sessions in a Spring/Hibernate stack?

  - by CaptainAwesomePants

  I'm trying to figure out a good design for a Spring/Hibernate app. When creating such an app, it appears like there are a handful of major decisions. The first major decision seems to be where to put the session/transaction boundary. It seems like I have 3 major choices: as a filter before controllers are even invoked, immediately below the controllers at the service call level, and stuffed way below the business level in repository calls. It seems to me like the right call is the middle path, but I'm not sure. I don't want my transactions open too long, but at the same time, I don't want to constantly worry about detached objects and lazy loading in the business logic. Still, there are some downsides. For instance, it makes it hard for the business logic to make a remote call without holding up a transaction for a few seconds. I wonder if there's a better way?

• Is it possible to call a procedure within an SQL statement?

  - by darren

  Hi everyone I thought I would use a stored routine to clean up some of my more complex SQL statements. From what I've read, it seems impossible to use a stored procedure within an sql statement, and a stored function only returns a single value when what I need is a result set. I am using mySQL v5.0 SELECT p.`id`, gi.`id` FROM `sport`.`players` AS p JOIN `sport`.`gameinstances` AS gi ON p.`id` = gi.`playerid` WHERE (p.`playerid` IN (CALL findPlayers`("Canada", "2002"))) AND (gi.`instanceid` NOT IN (CALL findGameInstances`("Canada", "2002"))); For example, the procedures 'findPlayers' and 'findGameInstances' are are stored routines that execute some SQL and return a result set. I would prefer not to include their code directly within the statement above.

• How do I bind a Listview SelectedItem to a Textbox using the TwoWay mode?

  - by Nick U

  I am very new to WPF and testing some things that I would like to include in an application that I will be working on. I have a 2 row ListView (bound to a textbox) with the names Scott Guthrie and Jon Skeet in it. I am trying to select "Scott Guthrie" in the ListView and have it populate the TextBox. I want to be able to edit the text and tab off and have the ListView updated. Edit:I removed the code since that really didn't add anything to the question.

• OpenCV to use in memory buffers or file pointers

  - by The Unknown

  The two functions in openCV cvLoadImage and cvSaveImage accept file path's as arguments. For example, when saving a image it's cvSaveImage("/tmp/output.jpg", dstIpl) and it writes on the disk. Is there any way to feed this a buffer already in memory? So instead of a disk write, the output image will be in memory. I would also like to know this for both cvSaveImage and cvLoadImage (read and write to memory buffers). Thanks! My goal is to store the Encoded (jpeg) version of the file in Memory. Same goes to cvLoadImage, I want to load a jpeg that's in memory in to the IplImage format.

• Using images and css file for a generated HTML UIWebView

  - by Tom

  Hi! I'm generating an HTML file for an app, and in this HTML file there's a link to a stylesheet and one to an image. Here's what I tried so far: NSMutableString *toReturn = [NSMutableString stringWithCapacity:100]; NSString *cssPath = [[NSBundle mainBundle] pathForResource:@"etapes.css" ofType:nil]; [toReturn appendFormat:@"<html><head><title></title><link href=\"%@\" media=\"all\" rel=\"stylesheet\" type=\"text/css\" /></head><body>", cssPath]; It generates the right full path to the right file, this is okay if I want to access it on my mac, but on the simulator or my iPhone it doesn't point to the right place at all... Do you have any idea of how could I make this? Thanks

• Powershell's import-clixml from string

  - by rocku

  Is there any way to run import-clixml cmdlet on a string or xml object? It requires a file path as input to produce ps objects and can't get input from an xml object. Since there is convertto-xml cmdlet which serializes ps object into xml object, why isn't there a convertfrom-xml, which would do the opposite? I am aware of System.Xml.Serialization.XmlSerializer class which would do just that, however I would like to stick with cmdlets to do this. Is there any way to do this with cmdlets (probably just with import-clixml), without creating temporary files?

• pros and cons of TryCatch versus TryParse

  - by Vijesh

  What are the pros and cons of using either of the following approaches to pulling out a double from an object? Beyond just personal preferences, issues I'm looking for feedback on include ease of debugging, performance, maintainability etc. public static double GetDouble(object input, double defaultVal) { try { return Convert.ToDouble(input); } catch { return defaultVal; } } public static double GetDouble(object input, double defaultVal) { double returnVal; if (double.TryParse(input.ToString(), out returnVal)) { return returnVal; } else { return defaultVal; } }

• Why many "normal" string in my flashlog file

  - by randy

  I suddenly find that there are many "normal" trace in my file flashlog.txt (supposed at your Window's location:{SysDrive}:\Documents and Settings{yourName}\Application Data\Macromedia\Flash Player\Logs). normal normal normal normal normal normal 1/10/2011 15:32:13.008 [INFO] org.spicefactory.parsley.core.view.impl.DefaultViewManager Add view root: null/flash.display::Stage normal normal normal But when I run the application with the FlashBuilder, the logging in the consul page is ok, it doesn't include any "normal" String. I am very confused by this, I thought that the output of the flashlog.txt file should be the same as that of the consul of FlashBuilder.And I don't think I have added such a stupid trace in my code. The question is how can I find out where these "normal" trace come from and how to remove it. This problem is resolved by restarting the computer as suggested.

• MSSQL 2000 Stored Procedure to Split Shift Times

  - by JClaspill

  I am being asked to alter a system to include the ability to have pay differentials based on hours worked. The old method included a stored procedure (MSSQL2000 db) that did the basics, but simply knows the start and end of every shift. So, this is the information I start with: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 8.643055 | 2011-01-08 07:57:35.557 | 2011-01-08 16:36:10.120 And I need to turn that into something like: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 4.00 | 2011-01-08 08:00:00.000 | 2011-01-08 12:00:00.000 Dave | ShiftDiff1 | 4.50 | 2011-01-08 12:00:00.000 | 2011-01-08 16:30:00.000 The ShiftDiff's range from hours to certain days, to a combo of both. Should I try to make the SQL2000 SP do this or pass the info back to my ASP.NET(C#) app and let it handle it, then send back?

• Mongomapper - unit testing with shoulda on rails 2.3.5

  - by egarcia

  I'm trying to implement shoulda unit tests on a rails 2.3.5 app using mongomapper. So far I've: Configured a rails app that uses mongomapper (the app works) Added shoulda to my gems, and installed it with rake gems:install Added config.frameworks -= [ :active_record, :active_resource ] to config/environment.rb so ActiveRecord isn't used. My models look like this: class Account include MongoMapper::Document key :name, String, :required => true key :description, String key :company_id, ObjectId key :_type, String belongs_to :company many :operations end My test for that model is this one: class AccountTest < Test::Unit::TestCase should_belong_to :company should_have_many :operations should_validate_presence_of :name end It fails on the first should_belong_to: ./test/unit/account_test.rb:3: undefined method `should_belong_to' for AccountTest:Class (NoMethodError) Any ideas why this doesn't work? Should I try something different from shoulda? I must point out that this is the first time I try to use shoulda, and I'm pretty new to testing itself.

• Hiding members in a C struct

  - by Marlon

  I've been reading about OOP in C but I never liked how you can't have private data members like you can in C++. But then it came to my mind that you could create 2 structures. One is defined in the header file and the other is defined in the source file. // ========================================= // in somestruct.h typedef struct { int _public_member; } SomeStruct; // ========================================= // in somestruct.cpp #include "somestruct.h" typedef struct { int _public_member; int _private_member; } SomeStructSource; SomeStruct *SomeStruct_Create() { SomeStructSource *p = (SomeStructSource *)malloc(sizeof(SomeStructSource)); p->_private_member = 0xWHATEVER; return (SomeStruct *)p; } From here you can just cast one structure to the other. Is this considered bad practice? Or is it done often? (I think this is done with a lot of the structures when using the Win32 API, but you guys are the experts let me know!)

• Is there a bash shortcut for traversing similar directory structures?

  - by Steve Weet

  The Korn shell used to have a very useful option to cd for traversing similar directory structures e.g. given the following directorys /home/sweet/dev/projects/trunk/projecta/app/models /home/andy/dev/projects/trunk/projecta/app/models Then if you were in the /home/sweet.... directory then you could change to the equivalent directory in andy's structure by typing cd sweet andy So if ksh saw 2 arguments then it would scan the current directory path for the first value, replace it with the second and cd there. Is anyone aware of similar functionality in bash. EDIT 1 Following on from Michal's excellent answer I have now created the following bash function called scd (For Sideways cd) function scd { cd "${PWD/$1/$2}" } EDIT 2 Thanks to @digitalross I can now reproduce the ksh functionality exactly with the code from below (With the addition of a pwd to tell you where you have changed to) cd () { if [ "x$2" != x ]; then builtin cd ${PWD/$1/$2} pwd else builtin cd "$@" fi }

• Maintaining both free and pro versions of an application

  - by Immortal

  I want to create a PRO version of my application for Android and was wondering how to structure my repository. For know I have a trunk and feature branches. I'd like to put a pro version in another branch but maybe there is a better way? For example, maybe I should create two branches - one for free version, the other for pro? Pro version will have additional features and will be ads-free, so eg. I don't want to include AdMob libraries in the pro version. Do you have any experience or suggestions as to what would be the best way to structure the repository in this case?

• What should I really release as open source when I use Berkeley DB (JE)?

  - by Ersin Er

  The Berkeley DB (JE) license information says: "...Redistributions in any form must be accompanied by information on how to obtain complete source code for the DB software and any accompanying software that uses the DB software.... For an executable file, complete source code means the source code for all modules it contains. It does not include source code for modules or files that typically accompany the major components of the operating system on which the executable file runs." If I build an abstraction level on top of BDB JE, should I open source only that library or any software that uses BDB JE indirectly?

• Using a nested group by statement or sub query to filter this result sets

  - by vivid-colours

  This question is a continuation of Changing this query to group rows and filter out all rows apart from the one with smallest value but with an extra bit at the end.... I have the following results set: 275 72.87368055555555555555555555555555555556 foo 70 275 72.87390046296296296296296296296296296296 foo 90 113 77.06431712962962962962962962962962962963 foo 80 113 77.07185185185185185185185185185185185185 foo 60 that I got from this query: SELECT id, (tbl2.date_modified - tbl1.date_submitted)/86400, some_value FROM tbl1, tbl2, tbl3 WHERE tbl1.id = tbl2.fid AND tbl1.id = tbl3.fid Notice there are 4 rows with 2 ids. I wanted to filter the rows to get only the minimum number in the second column. This fixed it: SELECT id, min((tbl2.date_modified - tbl1.date_submitted)/86400), max(some_value) FROM tbl1, tbl2, tbl3 WHERE tbl1.id = tbl2.fid AND tbl1.id = tbl3.fid GROUP BY tbl1.id so I got: 275 72.87368055555555555555555555555555555556 foo 70 113 77.06431712962962962962962962962962962963 foo 80 How can I change it to do the same but not include rows where the are other rows with some_value=90 ? I.e. 113 77.06431712962962962962962962962962962963 foo 80 I think I need some nested group or nested query ?! Many thanks :).

• Change spring bean properties at configuration time

  - by Nick Gerakines

  In a spring servlet xml file, I'm using org.springframework.scheduling.quartz.SchedulerFactoryBean to regularly fire a set of triggers. <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref local="AwesomeTrigger" /> <ref local="GreatTrigger" /> <ref local="FantasticTrigger"/> </list> </property> </bean> The issue is that in different environments, I don't want certain triggers firing. Is there a way to include some sort of configuration or variable defined either in my build.properties for the environment or in a spring custom context properties file that assists the bean xml to determine which triggers should be included in the list? That way, for example, AwesomeTrigger would be called in development but not qa.
