  • Linq and Lamba Expressions - while walking a selected list perform an action

    - by Prescott
    Hey, I'm very new to linq and lamba expressions. I'm trying to walk a collection, and when I find an item that meets some criteria I'd like to add that to another separate collection. My linq to walk the collection looks like this (this works fine): From i as MyCustomItem In MyCustomItemCollection Where i.Type = "SomeType" Select i I need each of the select items to then be added to a ListItemCollection, I know I can assign that linq query to a variable, and then do a for each loop adding a new ListItem to the collection, but I'm trying o find a way to add each item to the new ListItemcollection while walking, not a second loop. Thanks ~P

  • Trying to build automatic audio-conferencing capability into a WebApp

    - by Keller
    Hey all, I'm working with a team of relatively novice programmers, and we are trying to create a site that will have audio-conferencing capabilities such that whenever someone visits the page, they will immediately have audio-conferencing capabilities with everyone else on the page (5 people max). Can anyone point us in a general direction? Should we be looking into building a custom app, leveraging audio conferencing software, or trying to mimic a webex program? Would Adobe Stratus be useful in getting this kind of functionality? Does anyone have any ideas about how we would design something like this on a macro level? Sorry for the noobish question, but any guidance would be deeply appreciated. Thanks, Keller

  • GWT Custom Events

    - by Ciarán
    Hey I have a problem getting my head around how custom GWT event Handlers work. I have read quite a bit about the topic and it still is some what foggy. I have read threads here on Stackoverflow like this one http://stackoverflow.com/questions/998621/gwt-custom-event-handler.Could someone explain it in an applied mannar such as the following. I have 2 classes a block and a man class. When the man collides with the block the man fires an event ( onCollision() ) and then the block class listens for that event. Thanks

  • Using LINQ to query database through a proxy server of some kind?

    - by Mustafakidd
    Hey All Sorry for using (perhaps) the wrong lingo, but my question may be clearer if you view this diagram as you read it. http://dl.dropbox.com/u/13256/DIAGRAM.PNG Our client is requiring us to adhere to the server configuration (poorly) diagrammed in the above image. The web server is accessible over port 80 and is where our web application is hosted - a second firewall permits this web server to access a second server which in turn is the only server permitted to access the database server. My question is: How do I deploy a web application that uses LINQ-to-SQL in this environment? Is there a way to proxy my LINQ queries through the app server so that the database connection goes through that server? This is uncharted territory for me, as we always have had access to the DB server directly from our web server in the past. Any help is appreciated. Thanks Mustafa

  • Doctrine2 Mutliple DBs without Symfony2?

    - by ehime
    Hey guys I know that using the Doctrinebundle in Symfony2 it is possible to instantiate multiple DB connections under Doctrine... $connectionFactory = $this->container->get('doctrine.dbal.connection_factory'); $connection = $connectionFactory->createConnection(array( 'driver' => 'pdo_mysql', 'user' => 'foo_user', 'password' => 'foo_pass', 'host' => 'foo_host', 'dbname' => 'foo_db', )); I'm curious if this is the case if you are using PURELY Doctrine though?, I've set up Doctrine via Composer like so... { "config": { "vendor-dir": "lib/" }, "require": { "doctrine/orm": "2.3.4", "doctrine/dbal": "2.3.4" } } And have been looking for my ConnectionFactory class but am not seeing it anywhere? Am I required to use Symfony2 to do this? Thanks!

  • Dynamic typed language example using ANTLR

    - by wvd
    Hey all, I'm looking for some ANTLR examples, I tried googling a bit but I found certain things which didn't fit my requirments. I found the Mantra project, but it's statically typed and is 'too' big for me at this moment, then I found 'pie' as interpreter, which is dynamically typed, which what I want, but it uses a syntax-directed interpreter. I'm looking for a pretty small language which is dynamically typed and uses AST's if possible. It doesn't need to be advanced, if it would have classes I would already be very happy. Thanks, William van Doorn

  • Zend Framework - applying order by on a nested query

    - by Gublooo
    Hey guys This might be a very simple thing. Check out the normal sql query below (select * from shopping order by shopping_id desc limit 5) order by RAND() This query runs successfully in mysql - not sure if this is the right way of doing it - but it works. It gets the last 5 ids from shopping table and randomly orders them everytime I want to achieve this in Zend. I'm not sure how to execute the first part and then apply the RAND clause to the results - what I have below does not do that. $select = $this-select() -from(array('sh'='shopping')) -order('shopping_id desc') -limit(5) -order('RAND()');

  • IIS7 Rewrite changing default button

    - by Skoder
    Hey, I've run into a strange problem regarding default buttons in master pages and IIS7 rewrite module. All my content pages have default buttons set in the code-behind (on prerender), or they are in panels on the aspx page. This works fine on my local machine and on the production server. However, when I enable IIS7 URL Rewrite, the default button is always to the one in the master page. protected void LoginButton_PreRender(object sender, EventArgs e) { Button btnDefault = sender as Button; this.Page.Form.DefaultButton = btnDefault.UniqueID; } That's how I set my default button in the code-behind. I'm not sure what the rewrite module could be doing. Thanks for any help

  • ASP.NET Excel Export formatting question

    - by BWC
    Hey Guys, I've been banging my head on the wall over this issue for a couple days now and I need some help. I'm creating an excel file using ASP.net and everything is going just fine except one column has to be formatted as a decimal to 2 places but when it pulls into excel, excel automatically formats it as a whole number instead of keeping the decimal places. sw.Write(String.Format("{0:f}", CDbl(dr(14)).ToString("0.00"))) this produces "20.00" but when I open it in excel it's displayed as 20...if I select the whole column and format it as a number it gets displayed as 20.00 like it's supposed to but I don't want to have to do this (I can't do that) the file is supposed to be automatically picked up and imported into another system that needs the column to be a decimal. Any suggestions would be greatly appreciated.

  • jQuery plugin: Colorpicker

    - by New Developper
    Hey all, I'm using this colorpicker (http://www.eyecon.ro/colorpicker) and am trying to capture the hex value so that I can use it on the server side to store the selected color. If you check out the link provided, I'm using the last option: $('#colorSelector').ColorPicker({ color: '#0000ff', onShow: function (colpkr) { $(colpkr).fadeIn(500); return false; }, onHide: function (colpkr) { $(colpkr).fadeOut(500); return false; }, onChange: function (hsb, hex, rgb) { $('#colorSelector div').css('backgroundColor', '#' + hex); } }); My problem is that I can't seem to get the hex value from it...I've tried simply calling the name of the input to get its value, but it won't work (when you click away to make the colorpicker disappear, the input changes to 'style="display:none;"' so I can't get anything from it. Then, I tried pulling the value using some simple jQuery calls, but got nothing... Please help....

  • Google Docs viewer in IE

    - by Skoder
    Hey all, I've searched high and low for a solution, but can't find one. I'm using Google Docs Viewer to view PDF files. It's a great tool, but I can't seem to get it working in Internet Explorer (7 or 8). All my images come up as a 'missing' icon. If I view the file externally, it seems to load fine and it will start working (I'm assuming because the images are being cached). The document is being displayed in an iframe and works in all other browsers. Has anyone come across a solution to get it to work in IE? If not, is there an alternative that can display PPT and PDF files? Thanks

  • Flowplayer: Clicking on the player forces is to reload.

    - by PaulDavis
    Hey everyone, I've got this damn annoying bug (or wrong setting) that makes the player reload whenever it's clicked. It's set to play when you click, so when you click it, it reloads. The circle begins.... The reloading only happens in Firefox. In Safari (and I assume Chrome), the video opens in its own window. Not ideal, but it still plays. Here's the code for the player: (I can't share the link unfortunately, NDAs etc etc.) flashembed("player", "/flowplayer.commercial-3.0.7.swf", { config: { key: '#@xxxxxx', clip: { autoPlay: false, autoBuffering: true, url: "http://myvid.com/url.mp4", wmode: 'opaque' } } }); This site is full of complete geniuses, I hope one of you can help me out!

  • 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

  • Python Django vs ASP.NET MVC

    - by eddyc05
    Hey guys ! i'm fairly new at web development scene and i was wondering if you guys can help me break up the pros and cons of using python django vs asp.net mvc besides the maturity level of its framework. I have intermediate experience with JAVA. As of right now, i'm leaning towards python but i just wanted to make sure i am making the right choice. I find myself limited with books available on asp.net web developments. I am aware that there is the storefront example on the official asp.net site. However, that tutorial was a little hard for me to follow. I've done a research around and was hoping python could be my next available choice. There are more tutorials available online for python anyways. What do you guys think??

  • Insert rows into MySQL table while changing one value

    - by Jonathan
    Hey all- I have a MySQL table that defines values for a specific customer type. | CustomerType | Key Field 1 | Key Field 2 | Value | Each customer type has 10 values associated with it (based on the other two key fields). I am creating a new customer type (TypeB) that is exactly the same as another customer type (TypeA). I want to insert "TypeB" as the CustomerType but then just copy the values from TypeA's rows for the other three fields. Is there an SQL insert statement to make this happen? Somthing like: insert into customers(customer_type, key1, key2, value) values "TypeB" union select key1, key2, value from customers where customer_type = "TypeA" Thanks- Jonathan

  • How to prevent application thievery (specific to Android applications)?

    - by Berdon Magnus
    Hey, I was wondering what the most effective way of preventing people from stealing my application (downloading a copy of the .apk online rather than buying it). I've spent a lot of time on one in particular (Droidbox) and won't be releasing Sync until I can guarantee that the people who are providing illegal copies of the pro version aren't able to. Anyone implemented this? I've tried checking my package signature verses an the signature of an unsigned copy but it appears to be the same - perhaps I'm doing something incorrectly here. I'm unsure whether people actually distribute the signed .apk in which case I don't think signature validation would work to begin with... Please note, this question is specific to Android Marketplace Applications - the difference being, application delivery is out of my hands and I have no way of linking between a legitimate purchase and an illegal download.

  • Animating a font size change in a UITableView

    - by nickthedude
    Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

  • Changing a table-valued function that a stored procedure calls is not recognized?

    - by Peter
    Hey all I have a stored procedure sp that calls a table-valued function tvf. Sometimes I modify the tvf but when subsequently executing sp, the output from sp is the same as before the modification. It seems like it is cached or compiled or something. If I make some dummy change to the sp, then I get the right output of the sp. Is there some way, I can overcome this problem? In Oracle it is possible to re-compile all stored procedures, but I haven't been able to figure out how to do this in SQL Server? Any help is highly appreciated.

  • Getting my ip address

    - by AntonioCS
    Hey! I have a computer on a small network, so my ip is 192.168.2.100. I am trying to get my real ip. I download the no-ip client but that just seems like a lot of trouble for such a simple thing. I created this php script that got http://www.ip-adress.com/ page and retrieved the ip it gave me. Is there a simpler way? Either using C, WSH or something. Or if there is an easier way in php please tell me. When I get the ip I'll uploaded it to my ftp site so that I can see the ip from work.

  • Where to find iPhone system buttons and icons graphics?

    - by Ariel
    Hey guys, I'm trying to find a way to use the original Apple system buttons and icons in a web site. Is there a way to get these original graphics in png format? There are not-so-nice ways to obtain them of course. Two I was thinking of: Save them from this link, then convert to png. Take screen captures on the iPhone itself, and cut the icons from the saved images. Is anyone aware of a nicer way to obtain the original graphics? Does anyone know where they are stored on the Mac? Thanks :-) Ariel

  • Why does my Windows Form app timeout when repeatedly hitting IIS 7 externally?

    - by andy
    hey guys, I've got a very simple Windows Form app that hits an IIS 7 site about 2000 times in the space of a few seconds (using threads). When I run that app on the server itself, using either localhost or the ip address, everything is totally fine. However, when I run the app on my dev box, using the ip address, I get an error from the "GetResponse" method: The operation has timed out The App can definitely connect to the site, because it consistently either starts throwing the timeout error after 10 or so hits (no more than 11), or it throws the timeout error immediately. What's going on? It's hitting IIS 7 on a Windows Server 2008 VM (external box), Windows Firewall is OFF. My App is running locally on my dev box as the admin. cheers
