• Templated Control databinding to custom properties

  - by Dan Wray

  Is there some trick that I'm missing here? I've created a templated control, very simple. One single property on it, and I'd like to databind from the (viewmodel/datacontext of the) page in which it's hosted to a custom property on the control. The property will eventually be a vector type object, defining the position of the control, however in an attempt to get this to work I've tried reducing it to a basic string property. Each time I'm faced with "Set property 'SimpleGame.Classes.Sprite.Property' threw an exception.". I can't even catch the exception in a debug session, the set property code is not being executed. Do I need to use a dependency / attached property or something? I wouldn't have thought so...

• .Net opening and closing database connections

  - by Dan

  I designed the data access portion of our framework so that every time a business object needs to interact with the database it would have to open a connection, invoke the data access layer (to execute the query), and then close the connection. Then if it needed to run in a transaction it would open the connection, begin the transaction, invoke the data access layer (to execute the query) and then commit the transaction, close the transaction, and finally close the connection. I did it this way with the mindset of open late and close early... but what if I needed to call other BO's to submit data in a single transaction? Is there a better way to handle opening and closing connections as well as working with transactions? I'm a rookie in designing application architecture so I hope I'm not doing this wrongly... any help is appreciated.

  - by viky

  I have created a usercontrol which accept type of enum and assign the values of that enum to a ComboBox control in that usercontrol. Very Simple. I am using this user control in DataTemplates. Problem comes when there comes nested type.

Due to this I am not able to see my window at design time. Any help?

• bash bcmath functions

  - by Gordon

  I have two functions for GNU bc in a Bash script. BC_CEIL="define ceil(x) { if (x>0) { if (x%1>0) return x+(1-(x%1)) else return x } else return -1*floor(-1*x) }\n" BC_FLOOR="define floor(x) { if (x>0) return x-(x%1) else return -1*ceil(-1*x) }\n" echo -e "scale=2"$BC_CEIL$BC_FLOOR"ceil(2.5)" | bc Both functions work fine in interactive bc. bc does not seem to allow multiple functions on one line separated by ; though, so I have to echo -n | bc with newlines at the end of each function. The above output is 2.5, not the expected 3.0 that I get if I type it into bc -i myself. It seems that bash calls bc for each line of echo output, rather than echo'ing it all to a single instance. Is there any workaround for this?

• multiple modules under one solution

  - by Vicky

  I have a project under which various distributed applications are placed; the whole project is under a single dll. Hence, if any issue occurs we need to re-build the whole application to run or import to our server. I am looking for the best possible way to make the build process faster and also bit worried about the size of the DLL. Is it a good way to have separate dll for all the modules or split the application in multiple projects??? Can, anyone suggest the best way or example to deal with this situation. Any help would be appreciated. Thanks in advance.

• Detecting a Key Press Squashed by Another Application

  - by Eric Smith

  I have a WPF application I'm planning to use as an overlay for a DirectX game (specifically Bad Company 2). I'm using WM_KEYBOARD_LL hook to detect KeyDown events so I can bring my app to the foreground when a specific button is pressed. This works perfectly except for when the game is running (I've also noticed this problem with Window's "Chess Titans" so it may be a DirectX thing). As far as I can work out, when the game detects a keyboard press, it "eats" the event and doesn't pass the CallNextHookEx() method like it should, which would allow the key press message to be moved along to the next application in the queue. I'm wondering if there's any sort of work-around to this? It seems kind of unfair that a single application can just willy-nilly eat up messages like that. Thanks! :) Relevant MSDN documentation: http://msdn.microsoft.com/en-us/library/ms644985%28VS.85%29.aspx

• Setting up a SQL Membership Provider and attaching the MDF file in Visual Studio 2008

  - by aubreyrhodes

  I'm trying to set up a SQL Membership Provider for an ASP.NET MVC 1.0 and I'm having problems setting up the tables and stored procedures in the database. I've tried attaching both the applications current database and a blank database to my local SQLEXPRESS instance (using SSEUtil) and then running the aspnet_regsql wizard against them. When I detach the mdf file and try to load it in Visual Studio 2008, the data connection in the server explorer shows that the database has no tables or stored procedures. Am I missing a step or something here? I've been having a heap of trouble with compatibility between Visual Studio and SQLEXPRESS.

• django admin how to limit selectbox values

  - by SledgehammerPL

  model: class Store(models.Model): name = models.CharField(max_length = 20) class Admin: pass def __unicode__(self): return self.name class Stock(Store): products = models.ManyToManyField(Product) class Admin: pass def __unicode__(self): return self.name class Product(models.Model): name = models.CharField(max_length = 128, unique = True) parent = models.ForeignKey('self', null = True, blank = True, related_name='children') (...) def __unicode__(self): return self.name mptt.register(Product, order_insertion_by = ['name']) admin.py: from bar.drinkstore.models import Store, Stock from django.contrib import admin admin.site.register(Store) admin.site.register(Stock) Now when I look at admin site I can select any product from the list. But I'd like to have a limited choice - only leaves. In mptt class there's function: is_leaf_node() -- returns True if the model instance is a leaf node (it has no children), False otherwise. But I have no idea how to connect it I'm trying to make a subclass: in admin.py: from bar.drinkstore.models import Store, Stock from django.contrib import admin admin.site.register(Store) class StockAdmin(admin.ModelAdmin): def queryset(self, request): qs = super(StockAdmin, self).queryset(request).filter(ihavenoideawhatfilter) admin.site.register(Stock, StockAdmin) but I'm not sure if it's right way, and what filter set.

• Does different iVar name change retain count when used with property

  - by russell

  Here is 2 code snapshot- Class A:NSObject { NSMutableArray *a; } @property (retain) NSMutableArray *a; @implementation @synthesize a; -(id)init { if(self=[super init]) { a=[[NSMutableArray alloc] init]; } } @end Class A:NSObject { NSMutableArray *_a; } @property (retain) NSMutableArray *a; @implementation @synthesize a=_a; -(id)init { if(self=[super init]) { _a=[[NSMutableArray alloc] init]; } } @end Now what i need to know, is in both code instance variable assigned value directly rather than using accessor and retain count is 1? Or there is difference between them. Thanks. And one more things, apple recommended not to use accessor in init/dealloc, but at the same time ask not to directly set iVar. So what is the best way to assign value of ivar in init()??

• My Excel template is corrupted

  - by Prasanna

  I am using an Excel template (2003) for report generation. The workbook is of 4 sheets. The original template file works fine. But when I change the template (just remove a single static char), the report is getting generated but with some junk format. When I try opening the Excel file, I get this message: The following is a list of repairs: Damage to the file was so extensive that repairs were not possible. Excel attempted to recover your formulas and values, but some data may have been lost or corrupted. Please advise.

• Client Side Development - In Process/Completed Indicator Preferences?

  - by Brian

  Hello, I have been doing more client-side development, managing the UI on the client and submitting data to the server via web service calls. I'm not looking for implementation details, but was curious on developer preferences for displaying an operation in process and what to display when completed or even failed. As a for instance, just for clarification sake, what if you are submitting a profile form's data to a web service. I want to display that something's happening to the user, and give them a message that the form submitted successfully. I've in the past used a twitter-style message (that appears at the top), modal dialogs... I was curious what worked for others and any advice (what did the users like/not like, etc.). Again, technical details aren't needed. Thanks.

• IoC, Containers, and NServiceBus confusion

  - by andy

  Hey guys, here's my setup Castle Windsor is my container NServiceBus is itself using it's own container internally, Spring by default I'm implementing the PubSub config. Ok, if I have my Bus.Publish happening within my IWantToRunAtStartup class, then everything is fine. As a test for example on Run() we can start a timer and it'll go into a Service style loop. However, what if I want to abstract NServiceBus from my app, and have my app go: new CustomPulisherClass().Notify(ISomeMessage msg); In this situation, how do I implement CustomPublisherClass. My confusion is coming from the fact that NServiceBus is already running as a Service, it's already been "Started". How to I get at the correct instance of the Bus object? cheers andy

• Disabling Firefox spell checking in iframe-based text editors

  - by Piotr Sobczyk

  There is a lot of info around about how to disable spell checking in html textarea element by using spellcheck='false'. However to have text area with more advanced capabilities, one must use iframe with designMode = "on" (see e.g. this page, this is a way that RichTextArea is implemented in GWT) and I couldn't find a single post on that topic. It turns out that Firefox detects such advanced text areas and enables its spell checking in them. You can see it live by visiting this page from Firefox and entering some content to text field. If you inspect this code, you'll see no textarea tag, yet FF spell checking is still active. The only way I managed to disable it was setting designMode to off but... I need it to be on. The question is: Is there any possibility to disable spell checking in such cases, without setting designMode = "off"?

• Web App Server hardware question. Which configuration?

  - by JBeckton

  I am pricing some new servers and I am not sure which configuration to get. The server will be running some web applications for our company. Some of them are ASP.Net sites and some are ColdFusion. The OS will be Win Server 2008 Web or Standard Edition. Do I need 2 processors or will a single quad core handle it? Xeon multi core Hyperthreading or non Hyperthreading? I am going 64bit so I can go higher than 4 Gigs of Ram. I am shopping at Dell and there are so many options, i do not want to get too much hardware and not use half of it because that would be a waste of money and I do not want to get too little and have to ask for more money to upgrade it later.

• Creating a new nested resource

  - by Bobby B

  I'm working on a basic garden logging application which consists of gardens, plants and planted plants. Each user has one or many gardens, plants are master definitions, and a planted plant can be thought of as an instance of a plant in a specific user's garden. In my routes.rb file I have the following: map.resources :gardens do |gardens| gardens.resources :planted_plants, :has_many => :plant_log_entries, :collection => { :filter => :post, :choose_garden => :post} gardens.resources :garden_log_entries end map.resources :plants This makes sense to me when retrieving a list of planted_plants in a user's garden, but I'd like to create a planted_plant record from the index of plant. The problem is, a user can have multiple gardens. How can I create a new form for a planted_plant that allows the user to specify which garden should be used? The current route requires a garden_id - which makes sense for retrieval, but I'd like to supply that as a parameter for creation. Thanks in advance for any help!

• How to include associative table information and still retain strong typing

  - by mwright

  I am using LINQ to SQL to create strongly typed objects in my project. Let's say I have an object that is represented by a database table. This object has a "Current State" that is kept in an associative table. I would like to make a single db call where I pull back the two tables joined but am unsure how I should be populating that information into some sort of object to preserve strong typing within my model so that the view using the information can just consume the information from the objects. I looked into creating a view model for this but it doesn't seem to quite fit. Am I thinking about this in the wrong way? What information can I include to help clarify my problem? Other details that may or may not be important: It's an MVC project....

• How to check whether Application is Busy or not

  - by Chandan Shetty SP

  Hi, I am using "networkActivityIndicatorVisible" in UIApplication for showing network spinning gear in status bar if my WebView( I am setting "networkActivityIndicatorVisible = YES" in "webViewDidStartLoad" and reseting in "webViewDidFinishLoad" ) is busy. It works fine for single UIWebView. For Multiple UIWebViews i have used a "stack" to trace which webview is busy and which one is idle and it is working fine. My question is there is any way to know whether an application is busy or idle in application level(in UIApplication) instead of checking each webview so i can remove stack. Thanks.

• Has anyone run VxWorks on a desktop PC as a target

  - by Steve Roe

  Can I use a desktop PC to run VxWorks as the operating system? In other words, can a standard PC be used as a target processor? I'm not talking about hosting Workbench and a VxSim on the same machine. Rather, I'm considering running just VxWorks (and my application) on a PC. It seems feasible as long as we can configure a board support package, and write or obtain device drivers for the I/O cards on the PCI bus. What I wonder is, has anyone actually done this? I'm interested in saving a bit of money on hardware over a single board computer and cPCI backplane by using a spare desktop sitting around unused. The application is for a test set to be used in a lab. So, I don't need the portability, etc. of a typical embedded processor.

• If I want to play the same sound 10 times per second, must I have 10 copies of that sound in memory?

  - by mystify

  I have a sound that needs to get played 10 times per second. The sound is 1 second long. So it does overlap like 10 times. However, as far as I understand the Finch sound library, I would need 10 different instances of a sound in place so that I can play it 10 times at almost the same time. When I have just one instance, the sound would stop and play from the beginning on every iteration, but not overlap with itself. How to do that?

• Union on two tables with a where clause in the one

  - by Lostdrifter

  Currently I have 2 tables, both of the tables have the same structure and are going to be used in a web application. the two tables are production and temp. The temp table contains one additional column called [signed up]. Currently I generate a single list using two columns that are found in each table (recno and name). Using these two fields I'm able to support my web application search function. Now what I need to do is support limiting the amount of items that can be used in the search on the second table. the reason for this is become once a person is "signed up" a similar record is created in the production table and will have its own recno. doing: Select recno, name from production UNION ALL Select recno, name from temp ...will show me everyone. I have tried: Select recno, name from production UNION ALL Select recno, name from temp WHERE signup <> 'Y' But this returns nothing? Can anyone help?

  Hi, It is mentioned in the Apple's documentation that if we use UISPlitViewController in our app, then that should be the root view controller.

If we use SplitViewController as the root view. How will we show the splash screen which is displayed in a single view where as SplitVieController displays two ViewControllers. Please explain me the how this can be done.

Duplicate item or subitem entries should be merged and their numbers should be sorted. The subitems also should be sorted under respective item and their numbers should be also sorted. If same item is repeated in more than one place with subitems all the subitems should be merged under a single item and also subitems should be sorted

• Is there anyway of making json data readable by a Google spider?

  - by leeand00

  Is it possible to make JSON data readable by a Google spider? Say for instance that I have a JSON feed that contains the data for an e-commerce site. This JSON data is used to populate a human-readable page in the users browser. (I.E. The translation from JSON data to human displayed page is done inside the users browser; not my choice, just what I've been given to work with, its an old legacy CGI application and not an actual server-side scripting language.) My concern here is that, the google spiders will not be able to pickup/directly link to the item in question when a user clicks on it in google, being presented with an index page full of all the items, rather than being linked directly to the item they clicked on. Is there anyway of "informing" the google spider in the JSON that what they should feed the user a different link?
