  • Nhibernate and not-exists query

    - by Dan
    I'm trying to construct a query in NHibernate to return a list of customers with no orders matching a specific criteria. My Customer object contains a set of Orders: <set name="Orders"> <key column="CustomerID" /> <one-to-many class="Order" /> </set> How do I contruct a query using NHibernate's ICriteria API to get a list of all customers who have no orders? Using native SQL, I am able to represent the query like this: select * from tblCustomers c where not exists (select 1 from tblOrders o where c.ID = o.CustomerID) I have been unable to figure out how to do this using aliases and DetatchedCriteria objects. Any guidance would be appreciated! Thanks!

  • Why can't we have an immutable version of operator[] for map

    - by Yan Cheng CHEOK
    The following code works fine : std::map<int, int>& m = std::map<int, int>(); int i = m[0]; But not the following code : // error C2678: binary '[' : no operator... const std::map<int, int>& m = std::map<int, int>(); int i = m[0]; Most of the time, I prefer to make most of my stuff to become immutable, due to reason : http://www.javapractices.com/topic/TopicAction.do?Id=29 I look at map source code. It has mapped_type& operator[](const key_type& _Keyval) Is there any reason, why std::map unable to provide const mapped_type& operator[](const key_type& _Keyval) const

  • Command Prompt closes on Windows, using Wamp Server commands

    - by Sid
    Hey guys, I am following the tutorial on PHP with MySQL. In that tutorial ebook, they recommend us to use commands to set password for the MySQL. The command goes something like this, "mysqladmin -u root -p status" Now, I am using Windows XP and whenever I enter the command, the dos screen flashes and terminates. I am unable to note down the results, so the question: is there any way to stop command prompt from terminating on Windows machine? Looking forward to hear from you guys, thank you!

  • Git svn - no changes, no branches (except master), rebase/info is not working

    - by ex3v
    I know that similar questions were asked before, but I think my is a little bit different, so please don't point me to existing threads. I'm migrating our old svn repo to git. I did git svn clone path --authors-file abc.txt and everything seemend legit to me. Then I did git remote add origin xyz and git push --all origin and it also worked. I created this repo as test one, with only me having access to both local repo and origin. No changes were made in project held on this repo, nothing to commit, no pushing and so on. There is also only one branch, because someone initialized svn years ago without creating proper folder structure (branches, trunk, tags). Meanwhile someone pushed their work to svn, so I tried to git svn fetch (which worked), and git svn rebase which didn't, giving me error: Unable to determine upstream SVN information from working tree history Is there any reason why git svn decided to stop working?

  • MYSQL to UPDATE table if row with 2 specific columns exist or INSERT new row if it does not exist

    - by user2509541
    I have a MYSQL table that looks as follows: id id_jugador id_partido team1 team2 1 2 1 5 2 2 2 2 1 1 3 1 2 0 0 I need to create a query to either INSERT new rows in the table or UPDATE the table. The condition is based on id_jugador and id_partido, meaning that if I wanted to insert id_jugador = 2 and id_partido = 1, then it should just UPDATE the existing row with the new team1 and team2 values I am sending. And dont duplicate the row. However, if I have an entry id_jugador=2 and id_partido=3, since this combination does not exist yet, it should add the new row. I read about the REPLACE INTO but it seems to be unable to check combination of UNIQUE KEYS.

  • Find a variable with a given value in VS2008

    - by Aaron
    I have an instance variable with several members, many of which have their own members and so on. Using the debugger and watch variables, I found a string variable with a specific value that I need by diving into this variable's members. However, after spending some time on other things and coming back to this, I am now unable to find where this value is located. When I have my application paused, is there a way to search the values of variables in the current context for a given value? To clarify, if I have the given structure: myVariable | |--aMember1 | |--subMember = "A value" | |--aMember2 |--subMember = "Another value" Is there a way (possibly using the watch list in VS debugger) to search myVariable for any member or submember with the value "A value", returning to me the path myVariable->aMember->subMember?

  • Finding relative libraries when using symlinks to ruby executables

    - by dgtized
    Imagine you have an executable foo.rb, with libraries bar.rb layed out in the following manner: <root>/bin/foo.rb <root>/lib/bar.rb In the header of foo.rb you place the following require to bring in functionality in bar.rb: require File.dirname(__FILE__)+"../lib/bar.rb" This works fine so long as all calls to foo.rb are direct. If you put as say $HOME/project, and symlink foo.rb into $HOME/usr/bin, then __FILE__ resolves to $HOME/usr/bin/foo.rb, and is thus unable to locate bar.rb in relation to the dirname for foo.rb. I realize that packaging systems such as rubygems fix this by creating a namespace to search for the library, and that it is also possible to adjust the load_path using $: to include $HOME/project/lib, but it seems as if a more simple solution should exist. Has anyone had experience with this problem and found a useful solution or recipe?

  • How much effort does it take to spoof an Ip Address in a call to a webservice?

    - by Rory Becker
    I don't want to know how... Just how complicated.... I'm thinking of securing a webservice or 2 based on the incoming client ipaddress of the caller. Is this in any way secure? Surely if the IPaddress was being spoofed then the result would have to be sent back to the address that was being spoofed and therefore not reach the spoofer? Update: Ok so from what I can tell.... I should create a Gettoken() method which checks the IPaddress and passes out a cryptographically significant token with a timeout to any valid IP address. This is then required by any other method before any kind of side effect is allowed. Since an Attacker can't (likely) get the token without having a valid IP, he will be unable to validly call any of my "dangerous" webmethods ?

  • How to pass parameters with spaces via cstdlib system

    - by buchtak
    Hi, I have this windows console app which takes a file, do some calculations, and then writes the output to a specified file. The input is specified in "app.exe -input fullfilename" format. I need to call this application from my C++ program, but I have a problem with spaces in paths to files. When I call the app directly from cmd.exe by typing (without specifying output file for clarity) "c:\first path\app.exe" -input "c:\second path\input.file" everything works as expected. But, when I try using cstdlib std::system() function, i.e. std::system(" \"c:\\first path\\app.exe\" -input \"c:\\second path\\input.file\" "); the console prints out that c:\first is not any valid command. It's probably common mistake and has simple solution, but I have been unable to find any. Thx for any help.

  • WPF: Bind DataGrid to List<String>

    - by Sam
    Funny, how sometimes the simple things bite me in the behind. I can bind a DataGrid nicely to a Collection of some arbitrary class, using a DataGridTextColumn like this: <DataGridTextColumn Header="Name" Binding="{Binding Name}"/> Now I want to bind a DataGrid to a simple Collection. So since there is no property "Name" or something like that to bind to, how do I write the binding: <DataGridTextColumn Header="Name" Binding="{Binding ???}"/> String has no Property "Value" or something like that. And if I just write {Binding } I'll end up with a one-way-binding, unable to write changes back to the Collection. Thinking about it, I think it is not possible to bind to a collection, so I do need to wrap my string into a class? Or is there a way?

  • Launching The package installer.

    - by rantravee
    Hi, I'm looking for a way to automatically start the android Package Installer , after the browser finishes downloading an apk file . Any ideas on this ? Currently after the download is over the list of downloaded files is displayed and clicking on the downloaded apk launches the Package installer . (step which I'd like to automatize) I've thought on launching the instalation manually with code like this : intent.setAction(android.content.Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse("file:///sdcard/downloadedApk"), "application/vnd.android.package-archive"); startActivity(intent); ,but I'm unable to find when the download completes to execute the snipet above.

  • How to add space after elements added via jQuery

    - by ahsteele
    I am rendering a similar construct to the below with some server side code. The server side code inserts hard returns in between the project label and text fields. Not a big deal except the below jQuery code inserts the project label and text fields mashed together. var projectLabel = $('<label for="project">Project</label>'); var projectField = $('<input type="text" name="project" id="projectName" />'); projectLabel.insertBefore($(this)); projectField.insertBefore($(this)); Because of this discrepancy the elements rendered server side have a space between them while the ones rendered on the client do not. I've tried adding a nbsp; at the end of each line to no avail. Unfortunately, I have been unable to remove the hard returns outputted by the server side code. Further because of the space I can't fix this with CSS. What are my options for adding spacing via jQuery?

  • How to prevent an automerge using git?

    - by marckassay
    I am trying to merge a local branch into the master branch without having Git to do an automerge. I would like to “hand pick” what I would like to be merged into master. When I use Git’s difftool command, I am able to diff and select what I want to be added into the master branch. But then when I do a merge, I will lose what I selected prior because Git will do an automerge. I can commit the changes into master prior to the merge, but doing so seems unnatural. And Git’s mergetool is only available when there are conflicts from a merge. But if Git does an automerge then usually there aren’t conflicts, so I am unable to run the mergetool command.

  • before_filter not inheriting from parent controller correctly?

    - by Scott
    Sorry if this may be a stupid question but I'm unable get my filters to inherit the way the Rails 3 documentation is saying it should. Specifically I have an Admin controller that was generated via: rails generate controller admin I added only a single action to the admin controller, the before filter & the private filter method class AdminController < ApplicationController before_filter require_admin_creds def index end private def require_admin_creds unless current_user && current_user.admin? flash[:error] = ... redirect_to .... end end end I next then created my nested resources under the admin section with: rails generate scaffold admin/model While my admin index is indeed getting the filter, the admin/model index (or any other actions) are not. What is happening under the hood here that I must have excluded? Thanks in advance.

  • Running Firefox in the Windows service mode

    - by Leonid
    I'm writing a server running as a Windows service that by request invokes Firefox to generate a pdf snapshot of a webpage. I know it is a bad idea to run a GUI program in service mode, but the server nature of my program restricts from running it in the user mode. Running a user-level 'proxy' also is not an option, since there might be no interactive user logged-in on the machine with the server running. In my experiments Firefox successfully produced pdf when the service was running under a user account that was already logged-in. Obviously it didn't work in other cases: for Local System and user accounts that weren't logged-in. Under LocalSystem with 'Allow service to interact with desktop' option enabled I could see the Firefox started that reports that it's unable to find a printer. Since it wouldn't be practical to require an opened user session for the pdf server to run, is there any workaround for this except running the whole thing from a virtual machine?

  • Jquery Accordion and multiple slideshows

    - by Dipesh Parmar
    I've been using a lot of slideshows recently on my sites and one thing thats puzzled me is using more than one slideshow per page. I'm currently working on my own site, experimenting with Jquery Accordion. I've managed to adopt a very simple javascript slideshow, see below: http://dvpwebdesign.com/test/accordion/blank.html However i'm unable to either incorporate or use a different multiple slideshow plugin. I dont need slideshow navigation, so the The Cycle plugin works really well and i know you can use multiple slideshows. But if i either use Cycle alongside the current javascript slideshow, or only use the Cycle slideshow to avoid any possible conflict, the Accordion menu stops working. I just cant see what i am doing wrong, can anyone help?

  • Form submission and hyperlinks using GET and POST

    - by Jon
    I have a search resource, the user can perform searches by filling out a form and submitting it, the create action is called, the Search is saved, the show action is called, and the results are displayed. This all happens with the default POST, and all works fine. The user may want to save his search in the saved_search table (i don't use the Search table for this purpose as this table stores all searches for the purpose of compiling statistics, and gets cleared on a regular basis). Once the Search is saved, it can be re-run by clicking a hyperlink, this is where i start to get problems. I see no way of getting my hyperlink to run the create action of Search, with a POST request, and the necessary data. I then decided to try to get both form submission and the hyperlink to perform a search using a GET request, i was unable to get form_for to run my Search create action using a GET request, it always seems to get routed to my index action. Can someone suggest a good restful solution to this problem please. Many thanks

  • memcpy() safety on adjacent memory regions

    - by JaredC
    I recently asked a question on using volatile and was directed to read some very informative articles from Intel and others discussing memory barriers and their uses. After reading these articles I have become quite paranoid though. I have a 64-bit machine. Is it safe to memcpy into adjacent, non-overlapping regions of memory from multiple threads? For example, say I have a buffer: char buff[10]; Is it always safe for one thread to memcpy into the first 5 bytes while a second thread copies into the last 5 bytes? My gut reaction (and some simple tests) indicate that this is completely safe, but I have been unable to find documentation anywhere that can completely convince me.

  • iDevice for Dummies: Can a device be assigned multiple provisions (Personal/Enterprise)?

    - by Alex
    Hi guys, Is it possible to assign multiple provisions to an iDevice? To be honest, I'm not sure if I'm using the correct terminology, but basically, I'm developing an iPad app for a company and I've only been testing it in the simulator because I don't have a registration to the developer program and they haven't setup their enterprise registration yet either. And I'm sure you all know how limited the simulator is... I don't really care about the $99 it costs to join, but what I'm worried about is having my iDevices locked permanently to my personal registration and unable to switch back and forth to the enterprise registration. I'd appreciate it if someone can explain to me how the registrations work. And keep in mind, I'm a dummy. :) Thanks in advance!
