  • How do you resolve the common collsision between type name and object name?

    - by Catskul
    Since the convention is to capitalize the first letter of public properties, the old c++ convention of initial capital for type names, and initial lowercase for non-type names does not prevent the classic name collision class FooManager { public BarManager BarManager { get; set; } // Feels very wrong. // Recommended naming convention? public int DoIt() { return Foo.Blarb + Foo.StaticBlarb; // 1st and 2nd Foo are two // different symbols } } class BarManager { public int Blarb { get; set; } public static int StaticBlarb { get; set; } } It seems to compile, but feels so wrong. Is there a recommend naming convention to avoid this?

  • JQGrid: Dynamically set a cell to uneditable based on content

    - by Shawn
    I'm having some issues getting some cells (with cellEdit: true) to be non-editable even though the column is set to editable. I've tried many ways, like beforeEditCell, formatters, etc. None seem to work. The closest I've got is by setting a formatter to the column that I'd like to be editable and then using setCell to set the 'not-editable-cell' class (snippet below). The first time you click the cell, it unfortunately goes into edit mode, but if you click elsewhere and try to re-edit the cell, it's successfully uneditable. I've also tried using the same snipped but inside of beforeEditCell, it successfully stops the cell from being edited but in turn 'freezes' the grid. You can no longer select any other cell. function noEditFormatter(cellValue, options, rowObject) { if (cellValue == 'test') jQuery("#grid").jqGrid('setCell', options.rowId, 'ColName', '', 'not-editable-cell'); return cellValue; } Any help would be much appreciated.

  • MVC Forms Authentication with custom database

    - by AndrewVos
    I'm trying to get forms authentication working for an mvc site. I have a custom database with a users table, and I would like to do my own password validation. I am logging in my user like this: if (PasswordHasher.Hash(password) == dataUser.Password) { FormsAuthentication.SetAuthCookie(email, true); return true; } The problem is, when the session expires obviously the user has to login again. I am thinking I should be storing this Auth cookie in my users table? Update: I'm obviously in desperate need of more education in this area. I just noticed that the user stays authenticated even after an iisreset. I guess what I'm asking is how can I get persistent and non persistent authentication working properly. I want a user to not have to login again if they click "remember", and if they don't then their authentication should expire when the forms authentication is set to expire.

  • Using Enums that are in an external dll C#

    - by user1443233
    I have a project I am working that will involve creating one DLL that will be used across multiple other sites. Inside this DLL we need to reference about 10 Enums. The values of these Enums however will be different for each site the DLL is used on. For example: MyBase.dll may have a class MyClass with an attribute of type MyEnum. MyBase.dll is then referenced in MySite. MyStie will also reference MyEnums.dll which will contain the values for the MyEnum type. Is there any way to accomplish this? While building MyBase.dll, I know what enums will exist in side of MyEnums.dll. The problem is I cannot build MyBase.dll without specifically referenceing the MyEnums.dll, which is not created until the MyBase.dll is used in a specific project. I hope that makes sense and hope I can find an answer here. Thanks.

  • Wrong command in shell

    - by jask
    I have this command in a shell archive: sh -c $POSTGRESbin'psql -U '$POSTGRESuser' -h localhost -d '$POSTGRESdb' -c "select preview from '$fildCatalog' where preview <>'nodata' and id_registro in (select distinct(id_record) from e3_article_items where id_catalog=2101 and id_article in (select id_article from document_articles where id_document in(select distinct(id_document) from p3_logical_pages where id_logical_page in (select id_logical_page from p3_flatplan_pages where id_edition=1536 and id_logical_page is not null order by cast(pagenumber as numeric)))));"' > $queryFolder$highFile"_"$previewFile; But in <'nodata' appear an error and I don't know how can I resolve it.

  • Is there a database with git-like qualities?

    - by Mat
    I'm looking for a database where multiple users can contribute and commit new data; other users can then pull that data into their own database repository, all in a git-like manner. A transcriptional database, if you like; does such a thing exist? My current thinking is to dump the database to a single file as SQL, but that could well get unwieldy once it is of any size. Another option is to dump the database and use the filesystem, but again it gets unwieldy once of any size.

  • Jobs magically disappear from queue (delayed_job mongoid 2 on heroku)

    - by Hayk Saakian
    lets say i do something like arrs = Article.where(:body => nil) i'll have arrs.count is let's say 900 and i do arrs.each do |ar| ar.delay.download_via_diffbot #a method that takes some time, does some http, and writes a non-nil value to ar.body end now i'll watch the logs, and a wait a few minutes on ~5 dynos do the jobs, and do a count again: arrs.count is now ~800 so wtf, i thought i just told my workers to do ~900 jobs, what happened to the other 800? i can confirm that i'm only making ~100 HTTP requests b/c the api reporting shows me this, also simply watching the logs is telling enough that 900 jobs are not happening.

  • How can I clear the appcache on the Google Chrome iPad app?

    - by Jannis
    I've written a little HTML5 based web app that I am trying to debug on the iPad using the Chrome for iPad app. I have added a cache.manifest file to my app which has some heavy caching in it of most static resources however since I am now wanting to debug the app I need a way to clear this cache. I know that on Chrome for Mac you can use: chrome://appcache-internals/ however this page does not exist in the iPad app of Chrome. The regular "Clear Browsing Data" does not empty the appcache —at least not in my case. Does anyone know how I can clear the appcache for the Chrome iPad app?

  • Apache Modrewrite & 301 redirect- Dynamic URLs with characters.

    - by Ben Chesters
    I've been trying for weeks, literally, to rename these URLs and also ensure the old one is 301 redirected to the new one: www.example.com/?mod=11&p=215 - www.example.com/clean-url-section www.example.com/?mod=96&tab=6 - www.example.com/clean-url-section-2 Does anyone have any idea why I am having no luck, I got 500 server errors or nothing at all! Is it because of the question marks and characters? I'd be grateful for any help. I have tried this (below) and it seems to be redirecting to the http:// www.example.com/new-page (this page doesn't exist, as I only want it to rename the page BUT use a 301 so that search engines continue you to value it) RewriteCond %{query_string} mod=96&tab=6 RewriteRule (.*) http:// www. example.com/new-page? [R=301,L] Scratching my head!

  • Are there any medium-sized web applications built with CGI::Application that are open-sourced?

    - by mithaldu
    I learn best by taking apart something that already does something and figuring out why decisions were made in which manner. Recently I've started working with Perl's CGI::Application framework, but found i don't really get along well with the documentation (too little information on how to best structure an application with it). There are some examples of small applications on the cgi-app website, but they're mostly structured such that they demonstrate a small feature, but contain mostly of code that one would never actually use in production. Other examples are massively huge and would require way too much time to dig through. And most of them are just stuff that runs on cgiapp, but isn't open source. As such I am looking for something that has most base functionality like user logins, db access, some processing, etc.; is actually used for something but not so big that it would take hours to even set them up. Does something like that exist or am i out of luck?

  • JBoss, exploded jar vs compact jar.

    - by Win Man
    Hi, I am working on Java 1.6, JBoss 5.1, EJB 3, and Hibernate 2. Every time I deploy the ear, if the jar is a compact one (non-exploded), application doesn't work. However when I explode the jar and then add it to the ear, the app works fine. Tried restarting Jboss, doesn't help. The ear refers to numerous external jars; would the order of loading the jars be an issue? How can I make JBoss load external jars followed by the app jars? Thx. WM.

  • Erlang Edoc in Emacs

    - by Roberto Aloi
    Let's say that I have an Erlang function, with spec. -spec foo(integer(), string()) -> boolean(). foo(_Integer, _String) -> true. My dream would be to generate the edoc from this information within Emacs automatically. The generated code should look like: %%-------------------------------------------------------------------- %% @doc %% Your description goes here %% @spec foo(_Integer::integer(), _String::string()) -> %%% boolean() %% @end %%-------------------------------------------------------------------- -spec foo(integer(), string()) -> boolean(). foo(_Integer, _String) -> true. Does a similar feature already exist?

  • Django Problem - trying to access data entered into a form and feed it through a different page

    - by John Hoke
    OK, so let me give you an overview first. I have this site and in it there is a form section. When you access that section you can view or start a new project. Each project has 3-5 different forms. My problem is that I don't want viewers to have to go through all 3-5 pages to see the relevant information they need. Instead I want to give each project a main page where all the essential data entered into the forms is shown as non-editable data. I hope this makes sense. So I need to find a way to access all that data from the different forms for each project and to feed that data into the new page I'll be calling "Main". Each project will have a separate main page for itself. I'm pretty much clueless as to how I should do this, so any help at all would be appreciated. Thanks

  • Converting human readable date into integer values

    - by kahrn
    Hello all, I am looking to do something really simple. Merely convert a string, such as 'december' into something I can use with MySQL (such as '12'). At the moment I use a dict, month_map = { 'december': '12', 'november': '11', 'october': '10', 'september': '09', 'august': '08', 'july': '07', 'june': '06', 'may': '05', 'april': '04', 'march': '03', 'february': '02', 'january': '01' } and then month_map.get('december'). Does any function already exist within the standard python modules that can achieve this? Apologies if this has already been asked.. the questions I have found using search seem a little different.

  • Where do enumerations belong

    - by griegs
    At my current place of emplyment they were putting enumerations into the class they used them in. Whilst I didn't see any duplication of these enumerations I non the less thought that they didn't belong in the class so I moved them out into their own class. The reason I did that was that I wanted them to be re-usable w/out needing to reference the model class they were originally in. I got asked why I did that by the boss who disagreed with me as to my reasons for moving them and say nothing wrong with putting enumerations in a model class. So where should they be? Is it acceptable to leave enumerations in a class and hope that others in the project know to refactor your code if they want to re-use it elsewhere or should, as I did, you create an enumerations class and have them all in there?

  • grouping objects to achieve a similar mean property for all groups

    - by cytochrome
    I have a collection of objects, each of which has a numerical 'weight'. I would like to create groups of these objects such that each group has approximately the same arithmetic mean of object weights. The groups won't necessarily have the same number of members, but the size of groups will be within one of each other. In terms of numbers, there will be between 50 and 100 objects and the maximum group size will be about 5. Is this a well-known type of problem? It seems a bit like a knapsack or partition problem. Are efficient algorithms known to solve it? As a first step, I created a python script that achieves very crude equivalence of mean weights by sorting the objects by weight, subgrouping these objects, and then distributing a member of each subgroup to one of the final groups. I am comfortable programming in python, so if existing packages or modules exist to achieve part of this functionality, I'd appreciate hearing about them. Thank you for your help and suggestions.

  • Multithreading with STL container

    - by Steven
    I have an unordered map which stores a pointer of objects. I am not sure whether I am doing the correct thing to maintain the thread safety. typedef std::unordered_map<string, classA*>MAP1; MAP1 map1; pthread_mutex_lock(&mutexA) if(map1.find(id) != map1.end()) { pthread_mutex_unlock(&mutexA); //already exist, not adding items } else { classA* obj1 = new classA; map1[id] = obj1; obj1->obtainMutex(); //Should I create a mutex for each object so that I could obtain mutex when I am going to update fields for obj1? pthread_mutex_unlock(&mutexA); //release mutex for unordered_map so that other threads could access other object obj1->field1 = 1; performOperation(obj1); //takes some time obj1->releaseMutex(); //release mutex after updating obj1 }

  • What git gotchas have you been caught by?

    - by Bob Aman
    The worst one I've been caught by was with git submodules. I had a submodule for a project on github. The project was unmaintained, and I wanted to submit patches, but couldn't, so I forked. Now the submodule was pointing at the original library, and I needed it to point at the fork instead. So I deleted the old submodule and replaced it with a submodule for the new project in the same commit. Turns out that this broke everyone else's repositories. I'm still not sure what the correct way of handling this situation is, but I ended up deleting the submodule, having everyone pull and update, and then I created the new submodule, and had everyone pull and update again. It took the better portion of a day to figure that out. What have other people done to accidentally screw up git repositories in non-obvious ways, and how did you resolve it?

  • Changing newid() to newsequentialid() on an existing table

    - by cbp
    Hi, At the moment we have a number of tables that are using newid() on the primary key. This is causing large amounts of fragmentation. So I would like to change the column to use newsequentialid() instead. I imagine that the existing data will remain quite fragmented but the new data will be less fragmented. This would imply that I should perhaps wait some time before changing the PK index from non-clustered to clustered. My question is, does anyone have experience doing this? Is there anything I have overlooked that I should be careful of?

  • Rotate view of PDF on a WinForm

    - by Dabas
    I have to display a PDF inside a winform (c# on .net 2.0 framework). For now, I am using the ActiveX PDF control provided by Adobe. I have to disable the entire control so that a user can't print or save via right-click or hotkeys. Unfortunately, many of the documents need to be rotated (just viewed, not permanently saved that way). I'd like to allow them to rotate the view by pressing a button control. I've tried enabling the control then programmatically sending the hotkeys (ctrl shift +) using SendKeys and SendInput but the timing issues make this a non-viable solution. I've asked on the proper Adobe boards and they said it was not possible being that all of my clients will only have the reader version installed.

  • When did the idea of macros (user-defined code transformation) appear?

    - by Jay
    I have read McCarthy's 1960 paper on LISP and found no reference to anything that's similar to user-defined macros or normal order evaluation. I was wondering when marcos first appeared in programming language history (and also in Lisp history): When was the idea of user-defined code transformation (before interpretation or compilation) first described (theoretically)? What was the first programming language implementation to have Lisp-like macros (by "Lisp-like" I mean "using a readable Turing-complete language to do code-transformation")? (including non-Lisps -- Forth for example is quite old, but I'm not sure if the first Forth implementation already had "IMMEDIATE") What was the first Lisp dialect to have macros? Thank you!

  • How to merge existing row with new data in SQLite?

    - by CSharperWithJava
    I have a database full of simple note data, with columns for title, due date, priority, and details. There is also a _id column PRIMARY KEY int. Say I have a note in the table already with some data filled and the rest null. I also have a set of data that will fill all those fields. Is there a way that I can only write data to the fields that are NULL? I can't overwrite existing data, but I'd like to add data to NULL columns. I know the rowId of the target row. If my target row had rowId of 5, I could do something like this: UPDATE SET duedate='some date', priority='2', details='some text' WHERE _id=5 But that would overwrite all the data in that row, and I don't want to lose any data that might be there. How can I change this statement to avoid writing to non-null fields?

  • jqGrid: Is it possible to commit a cell change when tabbing off instead of pressing Enter?

    - by The Matt
    I have a simple in-line edit in my grid, and I want to commit the change when the user tabs off the textbox. The default behavior of jqGrid forces the user to press 'Enter' to commit the change, but this is non-intuitive for our users. onSelectRow: function(id) { $(gridCoreGroups).editRow(id, true, undefined, function(response) { alert("hello world"); } } I've worked my way through the events provided, but they all happen as a result of the user pressing 'Enter', which I want to avoid. Is there something I can wire up that would trigger an action when the user tabs off this cell?
