• How to create nested ViewComponents in Monorail and NVelocity?

  - by rob_g

  I have been asked to update the menu on a website we maintain. The website uses Castle Windors Monorail and NVelocity as the template. The menu is currently rendered using custom made subclasses of ViewComponent, which render li elements. At the moment there is only one (horizontal) level, so the current mechanism is fine. I have been asked to add drop down menus to some of the existing menus. As this is the first time I have seen Monorail and NVelocity, I'm a little lost. What currently exists: <ul> #component(MenuComponent with "title=Home" "hover=autoselect" "link=/") #component(MenuComponent with "title=Videos" "hover=autoselect") #component(MenuComponent with "title=VPS" "hover=autoselect" "link=/vps") #component(MenuComponent with "title=Add-Ons" "hover=autoselect" "link=/addons") #component(MenuComponent with "title=Hosting" "hover=autoselect" "link=/hosting") #component(MenuComponent with "title=Support" "hover=autoselect" "link=/support") #component(MenuComponent with "title=News" "hover=autoselect" "link=/news") #component(MenuComponent with "title=Contact Us" "hover=autoselect" "link=/contact-us") </ul> Is it possible to have nested MenuComponents (or a new SubMenuComponent) something like: <ul> #component(MenuComponent with "title=Home" "hover=autoselect" "link=/") #component(MenuComponent with "title=Videos" "hover=autoselect") #blockcomponent(MenuComponent with "title=VPS" "hover=autoselect" "link=/vps") #component(SubMenuComponent with "title="Plans" "hover=autoselect" "link=/vps/plans") #component(SubMenuComponent with "title="Operating Systems" "hover=autoselect" "link=/vps/os") #component(SubMenuComponent with "title="Supported Applications" "hover=autoselect" "link=/vps/apps") #end #component(MenuComponent with "title=Add-Ons" "hover=autoselect" "link=/addons") #component(MenuComponent with "title=Hosting" "hover=autoselect" "link=/hosting") #component(MenuComponent with "title=Support" "hover=autoselect" "link=/support") #component(MenuComponent with "title=News" "hover=autoselect" "link=/news") #component(MenuComponent with "title=Contact Us" "hover=autoselect" "link=/contact-us") </ul> I need to draw the sub menu (ul and li elements) inside the overridden Render method on MenuComponent, so using nested ViewComponent derivatives may not work. I would like a method keep the basically declarative method for creating menus, if at all possible.

• Using an embedded Word document to create a new instance of that document.

  - by jim

  For a variety of reasons that are immutable ... I have a Word document which contains a VBA application (the 'app document') which creates a new document based on another document (the 'template') which contains the framework for the new document. I want to embed the 'template' into the 'app document' so that I deliver one file and I know I am using the correct version of the 'template'. I have, so far, embedded the 'template' file into the 'app document' and can find it by looping through "ThisDocument.InlineShapes", looking at .Field.OleFormat.IconLabel to find the 'template' by its name. The inlineShape.Field.OleFormat.Object is the 'template' document itself, and I can .Activate it, which causes it to appear as a regular document. I try to do SaveAs, and it does in fact save the file as the name I give it, however, that saved-as file is not left open, just the embedded file. I can not .Activate the file and just save it, then open the saved file, but that seems more work than necessary. So ... is the way I am doing this "the way", or I have missed some obvious practice? TIA

• How do I create a Django ModelForm, so that it's fields are sometimes required, sometimes not?

  - by Graf

  Ok, here is the question. Imagine I have a ModelForm which have only two fields. like this one: class ColorForm(forms.Form): color_by_name = forms.CharField() color = forms.IntegerField(widget = forms.Select(choices=COLOR_CHOICES)) So a user can either input a color name, a choose it from a list. Color is required, but that doesn't mean, that user should enter it manually. There do I put validation, so that my code checks if user selected color in dropdownlist and if not then he should write it manually?

• Is C# WebAPI worth it? Can I use standart MVC4 to create my API?

  - by Steve

  I need to build a massive API and I'm trying out WebAPI instead of default MVC4 projects and it seems that it just makes things more difficult. Can have only 4 methods in controller Get, Post, Put, Delete, if I want more I need to modify route for that particular method FluentValidation won't work with WebAPI so I need to use DataAnnotations which I really don't want to. Can't use dynamic return data-types My question is: Would it really be that bad if I would use MVC4 project and use default ActionResults that return Json? What are real advantages of using WebAPI, why did they even made them in the first place if you can easily convert your project to API?

• How to create view model without sorting collections in memory.

  - by Chevex

  I have a view model (below). public class TopicsViewModel { public Topic Topic { get; set; } public Reply LastReply { get; set; } } I want to populate an IQueryable<TopicsViewModel> with values from my IQueryable<Topic> collection and IQueryable<Reply> collection. I do not want to use the attached entity collection (i.e. Topic.Replies) because I only want the last reply for that topic and doing Topic.Replies.Last() loads the entire entity collection in memory and then grabs the last one in the list. I am trying to stay in IQueryable so that the query is executed in the database. I also don't want to foreach through topics and query replyRepository.Replies because looping through IQueryable<Topic> will start the lazy loading. I'd prefer to build one expression and have all the leg work done in the lower layers. I have the following: IQueryable<TopicsViewModel> topicsViewModel = from x in topicRepository.Topics from y in replyRepository.Replies where y.TopicID == x.TopicID orderby y.PostedDate ascending select new TopicsViewModel { Topic = x, LastReply = y }; But this isn't working. Any ideas how I can populate an IQueryable or IEnumerable of TopicsViewModel so that it queries the database and grabs topics and that topic's last reply? I am trying really hard to avoid grabbing all replies related to that topic. I only want to grab the last reply. Thank you for any insight you have to offer.

• How do I create a patch compared to another changeset in Eclipse?

  - by Larsen

  I started working on an open source project that is using CVS where I want to submit patches. After having edited some files, I created a patch from the files that Eclipse showed as changed. Now I need to change a file for the second patch (that file is already in the first changeset), but the changes from the first changeset shouldn´t be in the second changeset. Therefore, I would need to somehow tell Eclipse that it should compare the changes to the result of the first changeset instead of to the CVS head revision. How can I do that?

• How do I create a simple Windows form to access a SQL Server database?

  - by NoCatharsis

  I believe this is a very novice question, and if I'm using the wrong forum to ask, please advise. I have a basic understanding of databasing with MS SQL Server, and programming with C++ and C#. I'm trying to teach myself more by setting up my own database with MS SQL Server Express 2008 R2 and accessing it via Windows forms created in C# Express 2010. At this point, I just want to keep it to free or Express dev tools (not necessarily Microsoft though). Anyway, I created a database using the instructions provided here and I set the data types appropriately for each column (no errors in setup at least). Now I'm designing the GUI in C# Express but I've kind of hit a wall as far as the database connection. Is there a simple way to access the database I created locally using C# Express? Can anyone suggest a guide that has all this spelled out already? I am a self-learner so I look forward to teaching myself how to use these applications, but any pointers to start me off in the right direction would be greatly appreciated.

• How do I create a ListBox In Ext-GWT ?

  Plain and Simple, I want to use a Listbox in my project, The demo here: http://www.extjs.com/examples shows no answer, In fact, I really hate it when companies show-off their 'complex' widgets in this manner and fail to show the most basic of all widgets. For example, I discovered class SimpleComboBox over the net till then I assumed that we required a class to contain list store, etc...

• Can you create a HIPAA compliant Amazon S3 Web Application?

  - by xkingpin

  I am facing some questions when trying to design an S3 application using ASP.NET MVC and trying to stay HIPAA compliant. My initial plan was to require an SSL connection to my web server, encrypt the images on my server, then send them to s3 using my private keys. Here's my obvious concerns: You cannot store unencrypted images in any temporary file cache when client views images within the browser. Even if I setup an ashx to generically handle the image in memory, couldn't this get stored in cache? Saying the images will be encrpyted because you will be connecting to my server via https still does not guarantee all browsers will not cache data. It's not possible to even consider the "Query String" with expiration option since data will be encrypted before being stored on disk at s3, and will again be decrypted at my server in memory. I think my only option would be to write/purchase some sort of ActiveX component that will not expose the image as a simple html image source or write my app as a client side WinForm application.

• How can I create numbered map markers in Google Maps V3?

  - by kaneuniversal

  I'm working on a map that has multiple markers on it. These markers use a custom icon, but I'd also like to add numbers on top. I've seen how this has been accomplished using older versions of the API. How can I do this in V3? *Note -- the "title" attribute creates a tooltip when you mouseover the marker, but I want something that will be layered on top of the custom image even when you're not hovering on top of it. Here's the documentation for the marker class, and none of these attributes seem to help: http://code.google.com/apis/maps/documentation/v3/reference.html#MarkerOptions Thank you . . . . Michael

• How to create XSD schema from XML with this kind of structure (in .net)?

  - by Mr. Brownstone

  Here's the problem: my input is XML file that looks something like: <BaseEntityClassInfo> <item> <key>BaseEntityClassInfo.SomeField</key> <value>valueData1</value> </item> <item> <key>BaseEntityClassInfo.AdditionalDataClass.SomeOtherField</key> <value>valueData2</value> </item> <item> <key>BaseEntityClassInfo.AdditionalDataClass.AnotherClassInfo.DisplayedText</key> <value>valueData3</value> </item> ... ... </BaseEntityClassInfo> The <key> element somehow describes entity classes fields and relationships (used in some other app that I don't have access to) and the <value> stores the actual data that I need. My goal is to programatically generate a typed Dataset from this XML that could then be used for creating reports. I thought of building some XSD schema from input XML file first and then use this schema to generate Dataset but I'm not sure how to do that. The problem is that I don't want all data in one table, I need several tables with relationships based on the <key> value so I guess I need to infer relational structure from XML <key> data in some way. So what do you think? How could this be done and what would be the best approach? Any advice, ideas, suggestions would be appreciated!

• How to create a session in PHP when there is a session on the same domain in Rails?

  - by Tony

  I have a Rails app on a subdomain - xyz.domain.com, and a PHP app on another subdomain - abc.domain.com When a user is logged into the Rails app, I would like to give them a session so that I can log certain events about that user in the PHP app but in the same database of the Rails app. I would essentially just expose an API that requires authentication. What is the best way to go about this? I am not storing the session in a database

• How do I create a stored procedure that calls sp_refreshview for each view in the database?

  - by Allrameest

  Today I run this select 'exec sp_refreshview N''['+table_schema+'].['+table_name+']''' from information_schema.tables where table_type = 'view' This generates a lot of: exec sp_refreshview N'[SCHEMA].[TABLE]'. I then copy the result to the query editor window and run all those execs. How do I do this all at once? I would like to have a stored procedure called something like dev.RefreshAllViews which I can execute to do this...

• EHCache on Coldfusion 9 - can I create multiple caches or disable it?

  - by ciaranarcher

  Hi all. We have been using EHCache with CF8 for a while now with no issues. We are now moving to CF 9 and it seems that the baked-in version of EHCache with CF 9 is actually conflicting with our EHCache setup. So is there: Any way to disable the baked-in version of EHCache? This would be a temporary solution. If we use the CF9 baked-in caching, is there any way to specify more than one cache in ehcache.xml and most importantly, to put into that specific cache via the tag? Many thanks in advance.

• Nested Usercontrols and ViewState

  - by Bob Smith

  I have a UserControlParent that dynamically loads UserControlChild. In the UserControlChild, I store a value using the ViewState object by doing a ViewState["count"] = myCount; On Postbacks, the ViewState returns a null. Is this because the UserControlChild is being loaded dynamically? If it helps, the UserControlParent is loaded dynamically in the ASPX page as well.

• How to create a win32 application without window in background with C?

  - by user563413

  The application do not need any window or console. It can be a console application if the console window can be removed or can be put into background. The application will do some simple tasks(such as cleaning rubbish files) and exit. I hope that the application should not be a windows service if possible. I hope that the application can be started with double-click in explorer window and run silently. When the application is running, I hope that the mouse cursor should not be changed to hourglass shape. That is to say, do not disturb the user when the application is running. Just run and exit silently. DO NOT NEED to run it when windows starts or user logins. I hope this can be done in C if possible. What should I do? Thanks!

• How do I create an Array into another Array?

  - by Timnkd

  I have the following JavaScript Array: var jsonArray = { 'homes' : [ { "home_id":"203", "price":"925", "sqft":"1100", "num_of_beds":"2", "num_of_baths":"2.0", }, { "home_id":"59", "price":"1425", "sqft":"1900", "num_of_beds":"4", "num_of_baths":"2.5", }, // ... (more homes) ... ]} I want to convert this to the following type of Array (pseudo code): var newArray = new Array(); newArray.push(home_id's); How can I do that? Notice how the newArray only has home_ids from the big jsonArray array.

• Can I create class properties during __new__ or __init__?

  - by 007brendan

  I want to do something like this. The _print_attr function is designed to be called lazily, so I don't want to evaluate it in the init and set the value to attr. I would like to make attr a property that computes _print_attr only when accessed: class Base(object): def __init__(self): for attr in self._edl_uniform_attrs: setattr(self, attr, property(lambda self: self._print_attr(attr))) def _print_attr(self, attr): print attr class Child(Base): _edl_uniform_attrs = ['foo', 'bar'] me = Child() me.foo me.bar #output: #"foo" #"bar"

• Recommendations for C# controls that can be used to create a hierarchical list of prioritised items?

  - by Mendokusai

  I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Anyone got any recommendations for controls for me to look at?

• How to create updateable panel using AjaxLink of Wicket?

  - by Arne

  I try to realize a link (in fact many links) that update a table in an website using an AjaxLink of Wicket. But I fail, the table is never updated (I have "setOutputMarkupId(true)" and call "addComponent", but there must be something other thats wrong). How can I realize a panel with a number of links and a table that displays dynamic data, dependent on the link clicked? Can someone give an example (Maybe two links, when the first one is clicked the table displays two random numbers from 1-10, when the second is clicked the table displays random numbers from 1-100)? Without reloading the entire page, but only the html for the table?

• How hard is it to create a not-so-random number generator?

  - by Duracell

  Backstory: So I was driving to band practice this evening. My car has a USB port where you can plug in a USB stick with MP3 files on it and the stereo will play them. I have about 100 MP3s on my stick so I pushed the 'Random' button. So from here to band practice, it played: Track 22 Track 45 Track 4 Track 11 Track 87 Track 66 Track 98 Then on the way home, it played Track 16 Track 27 Track 33 And then I stopped at the petrol station. I filled up, got back in the car and the stereo fired up again. It played Track 22 Track 45 Track 4 Track 11 Track 87 I thought, WTF? What's with this 'random' generator? What are they using as a seed, if not time? Is a car stereo so memory-tight that it can't even use the C stdlib? Does anyone know how this kind of thing happens?
