  • Grails: Problem with nested associations in criteria builder

    - by Mr.B
    I have a frustrating problem with the criteria builder. I have an application in which one user has one calendar, and a calendar has many entries. Seems straightforward enough, but when I try to get the calendar entries for a given user, I can't access the user property (MissingMethodException). Here's the code: def getEntries(User user) { def entries = Entries.createCriteria().list() { calendar { user { eq("user.id", user.id) } } } } I have even tried the following variation: def getEntries(User user) { def entries = Entries.createCriteria().list() { calendar { eq("user", user) } } } That did not raise an exception, but didn't work either. Here's the relevant parts of the domain classes: class Calendar { static belongsTo = [user: User] static hasMany = [entries: Entries] ... } class User { Calendar calendar ... } class Entry { static belongsTo = [calendar: Calendar] ... } When Googling I came across a similar problem noted in early 2008: http://jira.codehaus.org/browse/GRAILS-1412 But according to that link this issue should have been solved long ago. What am I doing wrong?

  • Visual C# GUI Designer basic tutorial

    - by cusack
    Hi, can you recommend a Visual C# Form Designer tutorial that is targeted at experienced programmers who have at least a basic knowledge of C# but are new to the VS C# Form Designer. At least it shouldn't be targeted at programming newbs, like Introduction to Visual C# 2008 Express Edition (it explains how a comment looks like in C#). So far I've found C# Programming Tutorial - Programming Winforms in C# on stackoverflow. Wishlist: ;-) I'm more interested in focus on the designer itself rather than an explanation of single gui-elements. In other words explaining separation between generated-code, what to not edit manually (visual-c#-designer-responsibility) and on the other hand the parts for which the programmer himself is responsible. So a little more abstract best-practice point of view pointing out some caveats would be great as well. I would prefer text over video as well, but that's minor. /Wishlist Perhaps even a Microsoft reference specific to the Visual c# forms designer (which I seem to have been unable to find) would be helpful.

  • JSF Conditional formatting for onmouseover and such attributes.

    - by Ben
    Hi, I'm trying to format a panelgrid according to a value in the backing bean. I'm currently trying this as the value of the onmouseover attribute: this.className=#{(actions.currentlySelectedActionButton == 0)?'actionButton actionButtonChosen':'actionButton'}; whereas the CSS looks like this: (the relevant parts): .actionButton { width: 100%; height: 20px; border: thin solid #000; cursor:default; } .actionButtonChosen { background-color: blue; } It's not working. Anyone spotting the error would help me greatly. Thanks!

  • Embed a Python persistance layer into a C++ application - good idea?

    - by Rickard
    say I'm about to write an application with a thin GUI layer, a really fat calculation layer (doing computationally heavy calibrations and other long-running stuff) and fairly simple persistance layer. I'm looking at building the GUI + calculation layer in C++ (using Qt for the gui parts). Now - would it be a crazy idea to build the persistance layer in Python, using sqlalchemy, and embed it into the C++ application, letting the layers interface with eachother through lightweigth data transfer objects (written in C++ but accessible from python)? (the other alternative I'm leaning towards would probably be to write the app in Python from the start, using the PyQt wrapper, and then calling into C++ for the computational tasks) Thanks, Rickard

  • Django aggregation query on related one-to-many objects

    - by parxier
    Here is my simplified model: class Item(models.Model): pass class TrackingPoint(models.Model): item = models.ForeignKey(Item) created = models.DateField() data = models.IntegerField() In many parts of my application I need to retrieve a set of Item's and annotate each item with data field from latest TrackingPoint from each item ordered by created field. For example, instance i1 of class Item has 3 TrackingPoint's: tp1 = TrackingPoint(item=i1, created=date(2010,5,15), data=23) tp2 = TrackingPoint(item=i1, created=date(2010,5,14), data=21) tp3 = TrackingPoint(item=i1, created=date(2010,5,12), data=120) I need a query to retrieve i1 instance annotated with tp1.data field value as tp1 is the latest tracking point ordered by created field. That query should also return Item's that don't have any TrackingPoint's at all. If possible I prefer not to use QuerySet's extra method to do this. That's what I tried so far... and failed :( Item.objects.annotate(max_created=Max('trackingpoint__created'), data=Avg('trackingpoint__data')).filter(trackingpoint__created=F('max_created')) Any ideas?

  • Using STL/Boost to initialize a hard-coded set<vector<int> >

    - by Hooked
    Like this question already asked, I'd like to initialize a container using STL where the elements are hard-coded in the cleanest manner possible. In this case, the elements are a doubly nested container: set<vector<int> > A; And I'd like (for example) to put the following values in: A = [[0,0,1],[0,1,0],[1,0,0],[0,0,0]]; C++0x fine, using g++ 4.4.1. STL is preferable as I don't use Boost for any other parts of the code (though I wouldn't mind an example with it!).

  • MERGE -v- UPSERT

    - by Kevin Ross
    Hi, I have an application I’m writing in access with a SQL server backend. One of the most heavily used parts is where the users selects an answer to a question, a stored procedure is then fired which sees if an answer has already been given, if it has an UPDATE is executed, if not an INSERT is executed. This works just fine but now we have upgraded to SQL server 2008 express I was wondering if it would be better/quicker/more efficient to rewrite this SP to use the new MERGE command. Does anyone have any idea if this is faster than doing a SELECT followed by either an INSERT or UPDATE?

  • Get Specific part of a String in Javascript

    - by streetparade
    I have a string containing something like this "Hello bla bla bla bla ok, once more bla können. // this is static: it doesn't change This is a text, this also a text. // this is dynamically added text it can change each time My name mysurename // this is also static text www.blabla.com " Now I have content and I have to get the first part of the string and the third part, I want to be able to have 3 parts, I think I have to split it using something like split(); string1 = "Hello bla bla bla bla ok, once more bla können.; string2 = ""; // i have this part string3 ="My name mysurename"; If it helps the first part ends with "können. " and the third part ends with the url above // its a fictional URL

  • ETW tracking from .net, user mode and driver

    - by Jack Juiceson
    Hi everyone, We have an application that parts of it are in .net, c++ usermode and C++ drivers. The application is divided into several executables that run on demand and communication with each other using LPC(the processes run in different sessions(winlogon)). Currently We have a home written logging service to which .net and c++ usermode communicate by sending LPC messages. The driver uses DbgPrint and is not always enabled, as it causes the code to run 30% slower(we have lots of logging). I want to have all the logs written in one place and preferably not writing the logger myself(I love log4cpp and log4net). The requirement is to write from all the executables and drivers into one place and to have minimal overhead. I have read that ETW is way to go, however I wasn't able to find already written logger that uses it like log4cpp or log4net. So basically my questions is, do you know if there is already implemented ETW appender for log4cpp and log4net I can use ?

  • How to create migration in subdirectory with Rails?

    - by Adrian Serafin
    Hi! I'm writing SaaS model application. My application database consist of two logic parts: application tables - such as user, roles... user defined tables (he can generate them from ui level) that can be different for each application instance All tables are created by rails migrations mechanism. I would like to put user defined tables in another directory: db/migrations - application tables db/migrations/custom - tables generated by user so i can do svn:ignore on db/migrations/custom, and when I do updates of my app on clients servers it would only update application tables migrations. Is there any way to achieve this in rails?

  • Parsing an RFC822-Datetime in .NETMF 4.0

    - by chris12892
    I have an application written in .NETMF that requires that I be able to parse an RFC822-Datetime. Normally, this would be easy, but NETMF does not have a DateTime.parse() method, nor does it have some sort of a pattern matching implementation, so I'm pretty much stuck. Any ideas? EDIT: "Intelligent" solutions are probably needed. Part of the reason this is difficult is that the datetime in question has a tendency to have extra spaces in it (but only sometimes). A simple substring solution might work one day, but fail the next when the datetime has an extra space somewhere between the parts. I do not have control over the datetime, it is from the NOAA.

  • CurvyCorners in Wordpress Theme only rounds some corners in IE - what am I doing wrong?

    - by user346602
    Hi, I'm implementing the CurvyCorners script on a blog I'm developing. The script works in IE on some parts of the blog, but not others. I've used the following code to add it to the functions.php file (as suggested by someone smarter than me): function load_curvy_corners() { wp_enqueue_script('curvycorners', get_bloginfo('stylesheet_directory') .'/scripts /curvycorners.src.js','','',true); } add_action('init', 'load_curvy_corners'); Here is the site I'm working on: http://www.bellissimafashions.com/blog/ The container and logo area appear rounded in IE, but the navigation area is still square and seems to take awhile to load now. I don't know if this has something to do with the fact the theme I'm using (Pure II by beathemes) has placed the left side in the footer.php?

  • Write an add-on or greasemonkey script to "Ajaxify" webpages in Firefox?

    - by Shizhidi
    Hello. I stumbled upon this add-on which "Ajaxifies" parts of its target website. https://addons.mozilla.org/en-US/firefox/addon/51789 I have a similar need like this. I want only part of the webpage's DOM to update upon receiving click on a link, since the website has a rather unified page layout. I have no experiences in writing FF add-ons but I did some basic Ajax and DOM before. So I am looking for programming tips on how to implement "Ajaxification" in a GreaseMonkey script, preferably. If it's not possible, making an add-on is also a sound choice which I'm willing to learn. Thanks in advance!

  • The best way to organize WPF projects

    - by Mike
    Hello everybody, I've started recently to develop a new software in WPF, and I still don't know which is the best way to organize the application, to be more productive with Visual Studio and Expression Blend. I noticed 2 annoying things I'd like to solve: I'm using Code Contracts in my projects, and when I run my project with Expression Blend, it launches the static analysis of the code. How can I stop that? Which configuration of the project does Blend use by default? I've tried to disable Code Contracts in a new configuration. It works in VS as the static analysis is not launched, but it has no effects in Blend. I've thinked about splitting the Windows Application in 2 parts: the first one containing the views of the WPF (app.exe) and the second one being the core of the project, with the logic code (app.core.dll), and I would just open the former project in Blend. Any thoughts about that? Thanks in advance Mike

  • Blending transparent textures with depth

    - by l.thee.a
    I am trying to blend textures which have transparent areas: glEnable( GL_TEXTURE_2D ); glBindTexture( GL_TEXTURE_2D, ...); glVertexPointer( 2, GL_FLOAT, 0, ... ); glEnable (GL_BLEND); glBlendFunc (GL_ONE, GL_ONE_MINUS_SRC_ALPHA); glDrawArrays( GL_TRIANGLE_STRIP, 0, 4 ); Unless I add glDisable(GL_DEPTH_TEST), transparent parts of the top textures overwrite everything beneath them (instead of blending). Is there any way to do this without disabling depth? I have tried various blending functions but none of the helped.

  • Accelerometer API for Laptops

    - by FreshCode
    Most IBM (and some Dell) laptops have built-in accelerometers to stop any moving parts during a sudden fall, but I was unable to find a standardised Windows API to access this data. I assume that each manufacturer would provide a driver to interface with the sensor. Which popular laptop brands come standard with accelerometers accessible from an API and which libraries should I use to access the data? Does an API* exist to abstract away the differences between different manufacturers? I am aware of the Windows 7 Sensor API, but I would like support for XP and earlier.

  • Cannot Debug Visual Basic 6 ActiveX Component On 64-bit OS

    - by Humanier
    Hi, The situation might sound a bit weird but I have to play with what I have. There's a Win2003 64-bit server OS and a legacy application written using Visual Studio 6. The app consists of two parts: ActiveX components written in VB6 and C++ code which uses them. I need to debug the components' code. I installed Visual Studio 6 on the server and I'm able to step into the component's code. Then I got following situation: 1) C++ code works until it needs to instantiate component A. 2) At this step we switch to VB6 and start debugging Component's A. 3) In the very beginning component A creates an instance of a class C exposed by component B. At this step VB6 debugger shows error message with title "OLEDB32.DLL" and following text: "Failed to load resource DLL C:\Program Files (x86)\Common Files\System\Ole DB\OLEDB32R.DLL" Additional information: The last step in initialization of the class C is opening an ADO connection to SQL server using OLEDB provider. I'd appreciate any ideas on how resolve this problem. Thanks in advance.

  • WWSAPI and setting "soapenv:Header" values

    - by Ben Burnett
    I'm trying to connect to a web service from a C++ app using WWS. I got the base connection working just fine. My XML message has two parts though, a header (soapenv:Header) and a body (soapenv:Body). the generated functions only fill in the body. How do I set the Header information? I assumed it has something to do with WsSetHeader() or WsAddCustomHeader() but can't seam to find the right values to use in the parameters. Can someone point me in the right direction here? I've been googling and trying to research this now for several days and am finding many sources for basic help with WWSAPI, but nothing seams to go deeper into how to use it for more advanced applications. any good links or resources to find more advanced help on WWSAPI? Thanks, --Ben Burnett www.burnett.ws

  • Windows CE 5.0 image building: Possible without Platform Builder?

    - by developer
    Is it possible to create Windows CE 5.0 images (ie: nk.bin) from VS2005/VS2008 without using Platform Builder? If so, how? Can a vendor BSP for WinCE 5 be loaded into VS2005/2008? Are there the parts to do this available for download from Microsoft (ie: the SDK), or must you buy the special bits (a la PB) from a "special distributor"? I know it is possible to build binaries (.dll, .exe) for WinCE 5.0 using VS, my question is about creating entire bootable CE 5.0 images for embedded platforms.

  • Indentation (and wrap-indentation) of debug strings output by printf()/fprintf() in C program

    - by mbaitoff
    I'm using a debug output using printf() in my functions, but the output goes to the console starting at the 1st columns. I'd like to distinguish the nesting level of functions by indenting their output strings each time I dive into the function (it's implemented easily having a static int indentlevel; variable, which is incremented at the beginning of a function, used as a space-filler-count and decremented at the end). But the flaw is that once the output line becomes too long to be wrapped at the console edge, lines' wrapped parts start at column 1 of the console. Should I take care about this, since once the output is redirected to a file, lines are, say, one-line-length, and widths of the lines depend only on the text file viewer settings?

  • Multiple rows with a single INSERT in SQLServer 2008

    - by Todd
    I am testing the speed of inserting multiple rows with a single INSERT statement. For example: INSERT INTO [MyTable] VALUES (5, 'dog'), (6, 'cat'), (3, 'fish) This is very fast until I pass 50 rows on a single statement, then the speed drops significantly. Inserting 10000 rows with batches of 50 take 0.9 seconds. Inserting 10000 rows with batches of 51 take 5.7 seconds. My question has two parts: Why is there such a hard performance drop at 50? Can I rely on this behavior and code my application to never send batches larger than 50? My tests were done in c++ and ADO.

  • Loginview control asp.net mvc

    - by vikitor
    Hello all, I have been searching and haven't got luck, I got a tutorial to use the loginview control in order to display or hide parts of the views to different user roles in my application. The thing is that the tutorial I've found is for ASP.NET and I've been told by one of my colleages that it is the same framework for ASP.NET MVC but the way to use it is different. Have you got any good tutorial to recommend? EDIT: I've got all my application set up, and the login and the roles already configured (via asp.net membership provider). This is all already running. The thing is that if I have role a and role b I want role a to be able to actually see the links to the actions it is authorized to work with, and not b for example. If in the Index of my application I've got a link to "Edit" and only the role a can access to the action, then it will be displayed just for logged in users that belong to role a, and not to those who belong to role b Thank you, Vikitor

  • Higher than high-level web frameworks or CMS's?

    - by Ben
    I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.
