  • What runs before main()?

    - by MikimotoH
    After testing on msvc8, I found: Parse GetCommandLine() to argc and argv Standard C Library initialization C++ Constructor of global variables These three things are called before entering main(). My questions are: Will this execution order be different when I porting my program to different compiler (gcc or armcc), or different platform? What stuff does Standard C Library initialization do? So far I know setlocale() is a must. Is it safe to call standard C functions inside C++ constructor of global variables?

  • Why do we need Web-Api? [closed]

    - by user437973
    I was just wondering what the deal is with Asp.net Web-Api. Why did we need a separate type of controller in order to facilitate varying content types for action results? Why wasn't this capability just baked into the ASP.Net MVC base controller? Anyway, I was just wondering if there was a compelling reason to use both types of controllers within the same project, assuming that the project was being freshly created, or if this project structure was due to an inherent technical limitation. Would it be possible to have ApiControllers fulfill the purpose of an MVC Controller in all cases by just serving HTML when that is the specified accept type? It just seems to me like a lot of unnecessary repetition to have to re-implement the same types of actions using both types of controllers if you want those actions to be available to your web application through the API and through the web interface.

  • move text from one div to another with javascript or mootools

    - by Ke
    Hi, I have two divs. I would like to move/populate the text from div id one to div id two using an onclick event. I am wondering how to do this? and also whether mootools can be used to accomplish the task or whether simple javascript is only necessary? <div id='one'> <ul> <input type="checkbox" onclick = "my_function()"/> <li>some text 1</li> <input type="checkbox" onclick = "my_function()"/> <li>some text 2</li> </ul> <div> <div id='two'> <div> Cheers in advance for any helps. Bangin my head against a brick wall here, because my javascript skillz are limited! Ke

  • How does OfType<T>() Work?

    - by TheCloudlessSky
    How does OfType() Work? I read this link about what's going on but how exactly does the LINQ provider know how to get all objects matching the specified type. I know the IQueryable<T> "chains" up requests and then evaluates when GetEnumerator() is called (right?). Specifically I want to know how does the framework quickly do type comparison? I wrote a method in a .NET 2.0 project that went like this (since 2.0 doesn't support these kind of features): public IEnumerable<TResult> OfType<TResult>() where TResult : class { foreach (TItem item in this.InnerList) { TResult matchItem = item as TResult; if (matchItem != null) { yield return matchItem; } } } Is this the best implementation?

  • WPF: Set style on immediate children only

    - by ollifant
    In my application I have a tab control which has several tab items. The problem is that I want to apply a style to these tab items, but to no other (nested) tab items. I have tried setting the following style on the tab control, but this also effects all children: <Style x:Key="tabControlStyle" TargetType="{x:Type TabControl}"> <Setter Property="TabItem.Template" Value="{StaticResource tabItemTemplate}" /> </Style> By using the code above I get the following error: 'TabItem' ControlTemplate TargetType does not match templated type 'TabControl', as TabItem and TabControl have the same DependencyProperty "Template", and the code tries to set the TabItemTemplate as TabControl- Template. Can anybody help me?

  • Field name being converted in Unit Tests [rails]?

    - by yar
    I am noting this strange behavior where one of my fields -- receive_empresa_test_info -- has worked fine though it's always been referred to as receive_empresa_info. In Functional Tests, though, the real field name is receive_empresa_test_info. What is going on here? Might this be some part of the Rails environment that I'm missing during testing?

  • F# equivalent of the C# typeof(IEnumerable<>)

    - by Rune FS
    I have a piece of code where I need to figure out if a given type implements IEnumerable (I don't care about the T) I've tried (t:System.Type in case you wonder) let interfaces = t.GetInterfaces() let enumerbale = interfaces.Any( fun t -> (t.GetGenericTypeDefinition() = typeof<IEnumerable<>>) however that wont compile (the compile don't like the <). I then tried let interfaces = t.GetInterfaces() let enumerbale = interfaces.Any( fun t -> (t.GetGenericTypeDefinition() = typeof<IEnumerable<'a>>) but get's a warning that 'a is constraint to obj. I Don't want to figure out if IEnumerable is implemented but IEnumerabl<. Any one know's the solution and btw feel free to comment on the code above as well. It's my first non-trivial F# program

  • Corona SDK - Make a character pass through a platform

    - by Andy Res
    I'm building a game that has a character which should jump up on multiple platforms. The jumping functionality is done, but I would like if the character is just below a platform (static body), when I press the "jump" button, the character should pass through that platform and then sit on it. Right now it collides with the platform, and character cannot jump on it. Do you have any idea how this can be achieved? Right now the platforms are represented by rectangles with "static" body type: local platform = display.newRect( 50, 280, 150, 10 ) platform:setFillColor ( 55, 55, 55) physics.addBody ( platform, "static", {density=1.0, friction=1.0, bounce=0 }) And I was thinking if I could change, or remove the body type of platform when the character collids with it, so he can pass trough platform, but I don't know how to do this, or in general if this will work... maybe there are some built in techniques on how to achieve the effect I want?

  • Problem in populating a dictionary object using Enumerable.Range() (C#3.0)

    - by Newbie
    If I do for (int i = 0; i < appSettings.Count; i++) { string key = appSettings.Keys[i]; euFileDictionary.Add(key, appSettings[i]); } It is working fine. When I am trying the same thing using Enumerable.Range(0, appSettings.Count).Select(i => { string Key = appSettings.Keys[i]; string Value = appSettings[i]; euFileDictionary.Add(Key, Value); }).ToDictionary<string,string>(); I am getting a compile time error The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. Any idea? Using C#3.0 Thanks

  • Wherewith replace Dictionary.Where(p => p.Key is T)

    - by abatishchev
    I have a System.Collections.Generic.Dictionary<System.Web.UI.Control, object> where all keys can be either type of System.Web.UI.WebControls.HyperLink or type of System.Web.UI.WebControls.Label. I want to change Text property of each control. Because HyperLink doesn't implement (why??) ITextControl, I need to cast Label or HyperLink explicitly: Dictionary<Control,object> dic = .. dic .Where(p => p.Key is HyperLink) .ForEach(c => ((HyperLink)c).Text = "something") dic .Where(p => p.Key is Label) .ForEach(c => ((Label)c).Text = "something") Are there ways to workaround such approach?

  • jQuery AJAX functions

    - by sundowatch
    I am using jQuery's load() function when getting a page to a div like that: content.php page is : <script type="text/javascript"> $(".content").load("asd.php"); </script> and asd.php is: <script type="text/javascript"> alert("Hello World"); </script> When load ajax finished alert() message appears 3 times. Actually it must appears only 1 time. So load() function get page 3 times. How can I get the page a time?

  • How do I combine two interfaces when creating mocks?

    - by sduplooy
    We are using Rhino Mocks to perform some unit testing and need to mock two interfaces. Only one interface is implemented on the object and the other is implemented dynamically using an aspect-oriented approach. Is there an easy way to combine the two interfaces dynamically so that a mock can be created and the methods stubbed for both interfaces?

  • How do I provide a string with a list of values to an "IN" statement

    - by Degan
    I am creating a string that is a list of comma-delimitted values by looping through the selections in a CheckBoxList. I am able to display this value, so I know that it is creating what I expect. I am attempting to pass this list to an IN statment in a SELECT query: SelectCommand="SELECT ThisDate, DATEPART(dw, ThisDate) AS Expr1 FROM fbCalendar WHERE (ThisDate &gt;= @ThisDate) AND (ThisDate &lt;= @ThisDate2) AND (DATEPART(dw, ThisDate) IN (@TheseDays))" <asp:ControlParameter ControlID="Label1" Name="TheseDays" PropertyName="Text" Type="String" /> This works fine as long as there is only a single item selected, but selecting a second item fails with the message: Conversion failed when converting the nvarchar value '4,5' to data type int. However, I do not understand when this would be converted to an INT. I have tried many different formatting attempts (such as encapsulating the string in parenthesis (e.g. "(4,5)" ) for the SELECT query, but I have yet to find the right one to make this work. It seems like formatting is the problem, but perhaps I am missing something else.

  • Python 3.1: Syntax Error for Everything! (Mac OS X)

    - by Nathan G.
    I updated to Python 3.1.3 (I've got OS X 10.6). If I type python in Terminal, I get a working 2.6.1 environment. If I type python3 in Terminal, I get a 3.1.3 environment. Everything looks fine until I do something. If I try to run print "hello", I get a syntax error. This problem is the same in IDLE. I tried deleting everything for 3.1 and then reinstalling, but it hasn't worked. Ideas? Thanks in advance!

  • Function Composition in Haskell

For example a test case call would be : (chain init tail reverse ) "Haskell!" the output should be lleksa I've tried to do this problem a few different ways including using the map function but I kept getting association problems. so i did chain :: Ord a => [a] -> a chain f g h x = f.g.h$x my error is Couldn't match expected type[t0->t1->t2->a0] When I type the problem directly into prelude like replacing f, g, h, x with the values it comes out right Is there even a way to do three functions, I've only seen two in examples

  • click event being fired twice - jquery

    - by maxp
    I have the following simplified html: <div class="foo" style="width:200px; height:200px;"> <input type="checkbox" /> </div> <script type="text/javascript"> $('.foo').click(function(){$(this).find('input:checkbox')[0].click();}); </script> Clicking the 200x200 div 'foo' works well, and raises the click event for the checkbox inside it. However when I exactly click the checkbox itself, it fires its 'normal' event, plus the jquery bound event above, meaning the checkbox checks itself, then unchecks itself again. Is there a tidy way to prevent this from happening?
