• Insert an ajaxified Webpart into an existing MOSS site

  - by mamoo

  Hi everybody, I need to code a webpart which purpose is to asynchronously fetch some documents and display them into an existing page. Unfortunately I have to face a lot of rescritcions and my struggle to find a solution seems useleess so far. 1) I cannot use Microsoft asp.net ajax 2) I must use Jsonp because the called service (page, whatever...) is outside the site's domain. That's not a big problem. 3) I have no possibility to alter the existing page code, so I cannot reference an external library such as JQuery. 4) For the same reason I have no possibility to call my methods on the window.onLoad event, so here the question is: how can I be sure that everything is correctly loaded before triggering my ajax call? 5) Since several instances of the same webpart can be placed into the same page, can there be some possible conflicts among the various js functions?

• What's an elegant way to conditionally add a class to an HTML element in a view?

  - by ryeguy

  I occasionally have to add a class to an html element based on a condition. The problem is I can't figure out a clean way of doing it. Here's an example of the stuff I've tried: <div <%= if @status = 'success'; "class='ok'"; end %>> some message here </div> OR <% if @status == 'success' %> <div class='success'> <% else %> <div> <% end %> some message here </div> I don't like the first approach because it's crowded looking and hard to read. I don't like the second approach because the nesting is screwed up. It'd be nice to put it in the model, (something like @status.css_class), but that doesn't belong there. What do most people do?

• EXTEND_MODEL_CASES SQL 2005 workaround

  - by user282382

  Hi, I have a time series based mining model in SQL 2005 Analysis Serveries. I understand in 2008 you can do what if analysis by using EXTEND_MODEL_CASES with a Natural Prediction Join. I'm looking for a workaround or some method of doing the same thing but with 2005. My time series has 3 inputs, and one predict_only. I'd like to use the prediction function to see what types of prediction it makes for 6-12 time intervals in the future with inputs in a separate table. Is there any way to do this or something similar? Thanks

• python object AttributeError: type object 'Track' has no attribute 'title'

  - by ccwhite1

  I apologize if this is a noob question, but I can't seem to figure this one out. I have defined an object that defines a music track (NOTE: originally had the just ATTRIBUTE vs self.ATTRIBUTE. I edited those values in to help remove confusion. They had no affect on the problem) class Track(object): def __init__(self, title, artist, album, source, dest): """ Model of the Track Object Contains the followign attributes: 'Title', 'Artist', 'Album', 'Source', 'Dest' """ self.atrTitle = title self.atrArtist = artist self.atrAlbum = album self.atrSource = source self.atrDest = dest I use ObjectListView to create a list of tracks in a specific directory ....other code.... self.aTrack = [Track(sTitle,sArtist,sAlbum,sSource, sDestDir)] self.TrackOlv.AddObjects(self.aTrack) ....other code.... Now I want to iterate the list and print out a single value of each item list = self.TrackOlv.GetObjects() for item in list: print item.atrTitle This fails with the error AttributeError: type object 'Track' has no attribute 'atrTitle' What really confuses me is if I highlight a single item in the Object List View display and use the following code, it will correctly print out the single value for the highlighted item list = self.TrackOlv.GetSelectedObject() print list.atrTitle

• What is the autoload class names structure, for the root "library" dir in a Zend Framework 1.10.2 pr

  - by Doron

  I have a project I created with Zend Framework 1.10.2. I usually use the application/models directory for new model files I create, and the auto loading is fine, so for example - My_Model_SampleClass is located application/models/SampleClass.php. However, I have just created a custom Exception class, and it does not fit in the models directory inside the application dir (at least the way I see it, I could be logically wrong), so I've created it in the root "library" dir, but I can't seem to find the correct class name + file name to use, so auto loading will be done correctly. BTW, I use a namespace for all custom classes I use, let's assume it's "My".

• Authlogic Multiple Password Validation

  - by Hock

  Hello, I'm using Authlogic to manage my user sessions. I'm using the LDAP add-on, so I have the following in my users model acts_as_authentic do |c| c.validate_password_field = false end The problem is that recently I found out that there will be some users inside the application that won't be part of the LDAP (and can't be added!). So I would need to validate SOME passwords against the database and the others against the LDAP. The users whose password will be validated against the database will have an specific attribute that will tell me that that password will be validated in my database. How can I manage that? Is it possible that the validate_password_field receives a "variable"? That way I could create some method that will return true/false depending on where the password validation will be done? Thanks!

• Extending Django-tagging, adding extra field to each tag?

  - by victorhooi

  heya, We're coding together a Django app to handle reviews of newspaper articles. Each newspaper article model will an arbitrary number of tags associated with it. Also, each tag will have an optional ranking (0 to 10). I was thinking of using django-tagging to do this (http://code.google.com/p/django-tagging/), but I'm not sure of the best way to add the ranking to the system. Should I extend django-tagging somehow? (Not sure if this is possible, without changing django-tagging's actual code?). Or is there a better way of achieving this? Cheers, Victor

• Using the ASP.NET membership provider database with your own database?

  - by Shaharyar

  Hello everybody, We are developing an ASP.NET MVC Application that currently uses it's own databse ApplicationData for the domain models and another one Membership for the user management / membership provider. We do access restrictions using data-annotations in our controllers. [Authorize(Roles = "administrators, managers")] This worked great for simple use cases. As we are scaling our application our customer wants to restrict specific users to access specific areas of our ApplicationData database. Each of our products contains a foreign key referring to the region the product was assembled in. A user story would be: Users in the role NewYorkManagers should only be able to edit / see products that are assembled in New York. We created a placeholder table UserRightsRegions that contains the UserId and the RegionId. How can I link both the ApplicationData and the Membership databases in order to work properly / having cross-database-key-references? (Is something like this even possible?) All help is more than appreciated!

• Why does ASP.NET web site reference assembly from GAC, when adding local reference?

  - by Konstantin

  When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file. Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.

• NHibernate mapping one table on two classes with where selection

  - by Rene Schulte

  We would like to map a single table on two classes with NHibernate. The mapping has to be dynamically depending on the value of a column. Here's a simple example to make it a bit clearer: We have a table called Person with the columns id, Name and Sex. The data from this table should be mapped either on the class Male or on the class Female depending on the value of the column Sex. In Pseudocode: create instance of Male with data from table Person where Person.Sex = 'm'; create instance of Female with data from table Person where Person.Sex = 'f'; The benefit is we have strongly typed domain models and can later avoid switch statements. Is this possible with NHibernate or do we have to map the Person table into a flat Person class first? Then afterwards we would have to use a custom factory method that takes a flat Person instance and returns a Female or Male instance. Would be good if NHibernate (or another library) can handle this.

• Code Profiling in the Windows Sidebar Environment

  - by Matt

  Does anyone know of a way I can code-profile my Windows Sidebar Gadget? I've played around with the code-profiling tool in IE8's "Developer Tools" and the code-profiling included in Visual Studio 2010, but I can't find a way to include the System.* API, which my gadget relies on (as it is standard in the Sidebar environment). The gadget also relies on cross-domain AJAX requests; which is normally permitted in the Sidebar environment. By code-profiling I primarily mean: Function call count Function execution time Any ideas would be much appreciated. Regards, Matt

• file_column not creating files, just empty tmp directory

  - by Yanaek

  Up to the end of December 2009 everything worked fine, so i assume that after some upgrades on servers (Ubuntu 8.10 and second Ubuntu 9.10) something stopped working. Model: class Product < ActiveRecord::Base belongs_to :category file_column :thumbnail, :magick = { :geometry = "150x100" } there is of course table 'products' in database, and it has column 'thumbnail' what's interesting that File actually is uploaded to server, it goes to the /tmp directory under RackMultipartXXXX-0 name, and it is unmodified image. The problem is, that then this file is not moved to 'tmp' dir under RAILS_ROOT/public/product/ nor the 'XX' (where xx means ID of a product) under public/product also. i don't know what to do, i spend few HOURS trying different versions of file_column, also trying to make new, test rails application only from scaffold, but then, in this new application problem was the same

• Flashing window in gnu screen

  - by gotts

  I really like gnu screen but there is a problem in my environment when I use it. Examle: username@domain:/var/www$ l Display all 130 possibilities? (y or n) when you click [Tab] to perform autocompletion there is a screen flashing for a very short period of time(looks like white screen but I can see it for a very-very short time). There isn't any problems with that when I execute the same action in normal/non-screen environment. This is what my .screenrc looks like: attrcolor b ".I" termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm' defbce "on" term screen-256color-bce

• Mootools not loading fast enough IE6

  - by Tom

  Very random and annoying problem with IE6. We keep our common JS files on a resources server so we only have to update them in one place. As well as our custom classes we also keep our build of mootools and more on the resources server and link to it in the head of our sites. This is fine in all the browsers accept IE6. In IE6 it seems to not loads the core quick enough from the external link before trying to process the mootools code in my site.js file. It will go wrong on the first line "windows.addEvent". If i put a mootools core in a folder where the site is though its fine. Does anyone know why it might be doing this and if so a way around it, but still keeping the files on the resources domain? Thanks Tom

• How should objects be in a Java game.

  - by Gabriel A. Zorrilla

  EDIT: i just deleted the entire post and reformulated the question to be more generic. I want to do a simple strategy game: map, units. Map: one class. Units: another class, self drawn. Simple questions: How does an unit should redraw itself on the map. A unit should be a JPanel or similar Swing component (just to be able to manage them as an entity with its own mousehandlers) or can be another thing, without neglecting the fact that it should be an autonomous object with its own action handlers and fields. Is this map-units model correct of a simple game that would help me to learn in a fun way Java and OOP fundamentals. Thats it!

• Adding custom context menu items to an Outlook MailItem using Outlook 2007 VSTO 3.0

  - by cbass

  Hi I've been trying to figure out how to create a context menu in VSTO 2007. I'm hoping that is possible. When I make this call. Dim commandBar As Microsoft.Office.Core.CommandBar = _word.CommandBars("Text") I get the following error. This object model command is not available in e-mail. I've look all over and from what I can tell it's not possible to add to the context menu in Office 2007. This doesn't seem right. I've also tried this event without any luck since it isn't being fired when right clicking on the MailItem ItemContextMenuDisplay(ByVal commandBar As Microsoft.Office.Core.CommandBar, ByVal selection As Microsoft.Office.Interop.Outlook.Selection) Hoping that someone can help. Thanks in advance.

• Django : json serialize a queryset which uses defer() or only()

  - by PlanetUnknown

  Now I've been using json serializer and it works great. I had to modify my queries where I started using the only() & defer() filters, like so - retObj = OBJModel.objects.defer("create_dt").filter(loged_in_dt__gte=dtStart) After I've done the above, suddenly the json serializer is returning empty fields - {"pk": 19047, "model": "OBJModel_deferred_create_dt", "fields": {}} If I remove the defer(), the serializer gives all the data correctly. import json from django.utils import simplejson from django.core import serializers json_serializer = serializers.get_serializer("json")() retObj = OBJModel.objects.defer("create_dt").filter(loged_in_dt__gte=dtStart) json_serializer.serialize(retObj, ensure_ascii=False) I've scratched my head on this for a while now. Any insight would be great. NOTE : I am using django 1.1

How can I run the custom action under the real user runnig the msi file or solve this problem in any other way?

• CSS Centering Issue - Div Centering appx 15px too far to the right

  - by Sootah

  I have a theme that I'm modifying for my site. I currently have it live on my test domain while I tinker with it before launch. http://www.networkgenius.org The #content-wrap div is centering, but too far to the right for some reason. I've absolutely no idea why it's doing this, especially since everything else is centering properly. What is the problem? I did add a 15px padding to the content-wrap area as I've changed the body's background color to the grey that you see and obviously didn't want the text pressed right up against the edges of the wrapper. Thanks for your help! -Sootah

• iframe accessing parent DOM?

  - by Yuval A

  How is it possible for a script within an <iframe> to have any notion of the page containing it? Can a script in the frame access any context outside of it? What about cross-domain? Up until now I believed an <iframe> is completely agnostic to the containing page, but I have seen an example which contradicts this belief. What exactly can and can't be done from within an <iframe> with respect to the containing page?

• 3d user experience with HTML5 and Javascript

  - by chako

  I've to build a 3D user experience with HTML5 and any required JS library which provides such functionality. 3D scene consists of a cylindrical pipe and surface. It has 360 degree rotation and can zoom in and out. As user selects a parameter, specific value of that parameter at various depth of pipe in surface should display. I've searched for HTML5 3d and JS libraries and found three.js could help for this.Also found this useful presentation on HTML 3d engine: http://projects.mariusgundersen.net/OnGameStart/#1 .But as this is my first time with HTML5 3d modeling, how should I initiate to build ? What parameters should be considered ? Which tools and libraries would best fit for such requirements ? I would like to create a 3d model using HTML5 and JS 3d engine as shown in the 1st image.

• insertNewObjectForEntityForName: inManagedObjectContext: returning NSNumber bug?

  - by beinstein

  I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. All of a sudden I'm now dumbfounded by an error. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

• Free for personal use license?

  - by Lance May

  I'm trying desperately to find a software licensing model that would allow me to make my product completely open to the public domain for personal use/modification, but would be able to be sold commercially. I know such a beast exists, and I'm sure in many flavors. I just can't find it. ;( What I'm hoping for is a way to allow people the opportunity to benefit from the product in an "open source" fashion, while still allowing me to have a revenue on it to be able to continue development full time. Thanks much in advance.
