  • Get ahold of session in command object in Grails

    - by UltraVi01
    How can I get the session from within a command object? I have tried: import org.springframework.security.context.SecurityContextHolder as SCH class MyCommand { def session = RCH.currentRequestAttributes().getSession() } This throws java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

  • Sum of Fibonacci numbers

    - by Rafal
    Hi, I'm rather new to Haskell. The problem is to find the sum of all even Fibonacci numbers not greater than 4 million. I can't use lists. If I understand correctly, the below solution is wrong, because it uses lists: my_sum = sum $ filter (even) $ takeWhile (< 4000000) fibs Where fibs is the list of all Fibonacci numbers. Somehow, I find it difficult not to think in Haskell in terms of lists. Could anyone guide me to a solution to this problem? Regards

    - by xarzu
    What are the limits of writing a C# app when you want a truly impressive GUI? At what point does one have to leave Visual C# behind and go into WPF? Also, if I choose to go with WPF, do I have to ditch the Visual Studio IDE and go with Expression Studio?

  • Is it possible to have 'sub-templates' when using MailDefinition

    - by Dan
    I am using the MailDefinition class to create html emails for my site. The only problem I am having is that there is alot of repetition in the string templates. For example the email footer along with all the associated html and css has to be repeated in each template type. Is there a way to have sub-template? or some mechanism for avoiding this repetition?

  • SQL SERVER Spatial Data

    - by Sam
    Hi All, I am struggeling finding an effectient way to find a distance between a Point that interetcts a polygon and the border of that polygon. I was able to use the STDistance comparing the point to every point that made up the polygon but that is taking a lot of time. Using SPatial indexed wasnt much helpful because the STDistance is not part of any constraint and even when I did put the constraint, the index didnt help much. I appreciate any feedback. Thanks.

  • How to render the properties of the view model's base class first when using ViewData.ModelMetadata.

    - by Martin R-L
    When I use the ViewData.ModelMetadata.Properties in order to loop the properties (with an additional Where(modelMetadata => modelMetadata.ShowForEdit && !ViewData.TemplateInfo.Visited(modelMetadata))), and thereby create a generic edit view, the properties of the view model's base class are rendered last. Is it possible to use a clever OrderBy() or is there another way to first get the properties of the base class, and then the sub class'? Reverse won't do the trick since the ordering of each class' properties is perfectly fine. A workaround would of course be composition + delegation, but since we don't have mixins, it's too un-DRY IMHO, why I seek a better solution if possible.

  • SharePoint Server 2007 Stops Responding to External Requests

    - by Mountain Deux
    We have a SharePoint2007 server running on a Windows Server 2003 Box. The box itself is quite old but has not experienced any weird issues. Recently SharePoint has begun to show some strange behavior. One of the most annoying things is that once in a while, the sharepoint sever stops responding to requests outside our network. Internally, you can still browse everything that has to do with sharepoint but outside, nothing. If i reset the server it will start responding again. I am just not sure what makes it stop responding to users on the outside in the first place. Resetting the WWW publishing service does no good.

  • C++/CLI and C#, "Casting" Functions to Delegates, What's the scoop?

    - by Jacob G
    In C# 2.0, I can do the following: public class MyClass { delegate void MyDelegate(int myParam); public MyClass(OtherObject obj) { //THIS IS THE IMPORTANT PART obj.SomeCollection.Add((MyDelegate)MyFunction); } private void MyFunction(int myParam); { //... } } Trying to implement the same thing in C++/CLI, it appears I have to do: MyDelegate del = gcnew MyDelegate(this, MyFunction); obj-SomeCollection-Add(del); Obviously I can create a new instance of the delegate in C# as well instead of what's going on up there. Is there some kind of magic going on in the C# world that doesn't exist in C++/CLI that allows that cast to work? Some kind of magic anonymous delegate? Thanks.

    Hi, I want to insert CLOB value into my Oracle database and here is the what I could do. I got this exception while inserting operation "ORA-01461: can bind a LONG value only for insert into a LONG column". Would someone able to tell me what should I do? Thanks.

  • What is a simple way to add a timer to a method

    - by John
    The following is in C#. I'm trying to do something very simple (I think). I have a method that loads an XML document XDocument doc = XDocument.Load(uri); , but I don't want to tie up pc resources if there are issues (connectivity, document size, etc.). So I'd like to be able to add a timeout variable that will cut the method off after a given number of seconds. I'm a newbie when it comes to asynchronous programming and find it confusing that there are so many examples written so many different ways . . . and none of them appear simple. I'd like a simple solution, if possible. Here's my thoughts so far on possible solution paths: 1) A method that wraps the existing load public XDocument LoadXDocument(string uri, int timeout){ //code } 2) A wrapper, but as an extension method XDocument doc = XDocument.LoadWithTimeout(string uri, int timeout); 3) A generic extension method. Object obj = SomeStaticClass.LoadWithTimeout(??? method, int timeout); 3), on its face seems really nice, because it would mean being able to generically add timeouts to many different method calls and not specifically tied to one type of object, but I suspect that it is either i)impossible or ii) very difficult. Please assist. Thanks.

  • How to Implement Grep into CGI script Please?

    - by Joey jie
    Hi all! I am having difficulty figuring out how to implement grep into my CGI script. Basically I will receive a value of eg. 1500 from a HTML page. The CGI script then runs and compares 1500 to a text file. When it finds 1500 it prints the entire line and displays it on the webpage. I would like some tips and pointers on how to do this please. I understand that this involves grep but I don't really know how to put it in. #include <stdio.h> #include <stdlib.h> int main(void) { char *data; long m,n; printf("%s%c%c\n", "Content-Type:text/html;charset=iso-8859-1",13,10); printf("<TITLE>Webpage of Results</TITLE>\n"); printf("<H1>Temperatures</H1>\n"); data = getenv("QUERY_STRING"); The HTML passes the variable time=1500. I understand (correct me if I am wrong) that QUERY_STRING will contain 1500?

  • How to use FTP's APPEND command in a script?

    - by btelles
    Hi there, For some reason when I try to use "append" while inside an FTP script, the ftp client appears to hang. I've tried all sorts of different variations (for example, including the destination filee and not, using quotes and not), and all I ever get is a "No such file or directory" error (and I KNOW it's there) or it hangs on an 200 Request OK and never does anything. ftp> open ibm.some_server Connected to ibm.some_server 230 USER1 is logged on. Working directory is "USER1.". Remote system type is MVS. ftp> cd 'Z.TABS.' 250 "Z.TABS." is the working directory name prefix. ftp> append 'SAMASCPY' 'SAMASCPY': No such file or directory ftp> append SAMASCPY 200 Port request OK. Anyone know what could be going on?

  • Ruby On Rails -

    - by Adam S
    I am trying to create a collection_select that is dependent on another collection_select, following the railscasts episode #88.. The database includes a schedule of all cruise ships arrival dates. See attached schema diagram,... (The arrow side of the lines indicate has_many, the non-pointy side indicates belongs_to) In the "booking/new" view I have a collection_select for choosing a cruiseline, then another collection_select will appear for selecting a ship, then another for selecting the date that ship is in. If I ONLY put a collection_select for shipshedule it works fine(because of the direct association with the bookings model). However, if I try to add a collection_select for cruiselines....it breaks(Im assuming because their isnt a direct association). The collection_select for cruiselines returns an undefined method error for "cruiseline_id".....if I simply use "id" the collection_select works, but of course isnt fully functional due to incorrect naming of the form field. I have tried "has_many :shipschedules, :through = :cruiseships" in the cruiseline model and "has_many :bookings, :through = :shipschedules" in the cruiseships model... As you can see in the diagram, I need to access the cruiseships and cruiselines model through the bookings model. I have the models set up so a cruiseline has_many cruiseships, a cruiseship has_many shipschedules, and a shipschedule has_many bookings. But, the bookings model cant directly access the cruiseline model. How do I accomplish this? THANKS!!! http://www.adamstockland.com/common/images/RoRf/PastedGraphic-2.png http://www.adamstockland.com/common/images/RoRf/PastedGraphic-1.png

  • Named Blueprints with factory_girl

    - by Jason Nerer
    I am using Factory Girl but like the machinist syntax. So I wonder, if there is any way creating a named blueprint for class, so that I can have something like that: User.blueprint(:no_discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader false name "foolish" salt "21746899800.223524289203464" end User.blueprint(:discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader true name "deadbeef" salt "21746899800.223524289203464" discount_rate { DiscountRate.make(:rate => 20.00) } end DiscountRate.blueprint do rate {10} not_before ... not_after ... end Is there a way making factory_girl with machinist syntax acting like that? I did not find one. Help appreciated. Thx in advance Jason

Or am I just missing something obvious?
