  • Getting rid of function's argument

    - by Max
    It is better to explain my intention with code. So right now I have the following code: class A, IInterfaceUsedByB { } class B { void func(A someObject) { func2(someObject, 1); func3(someObject, "string"); func4(someObject, new MyObject()); } func2(A someObject, int val); func3(A someObject, string val); func4(A someObject, C val); } Where func2, func3, func4 do need references to someObject. I want to change this to void func() { with(someObject, () => { func2(1); func3("string"); func4(new MyObject()); } ); } Or even better to void func(someObject) { func2(1); func3("string"); func4(new MyObject()); } So that I don't have to drag this someObject around, but I should still be able to use it inside func2,3,4. I can use any of the three languages (C#, F# or IronPython) for this. UPDATE In the ideal solution class B would be independent of A. func* functions only depend on a small interface of A consisting of 2 methods.

  • Using overloaded operator== in a generic function

    - by Dimitri C.
    Consider the following code: class CustomClass { public CustomClass(string value) { m_value = value; } public static bool operator==(CustomClass a, CustomClass b) { return a.m_value == b.m_value; } public static bool operator!=(CustomClass a, CustomClass b) { return a.m_value != b.m_value; } public override bool Equals(object o) { return m_value == (o as CustomClass).m_value; } public override int GetHashCode() { return 0; /* not needed */ } string m_value; } class G { public static bool enericFunction1<T>(T a1, T a2) where T : class { return a1.Equals(a2); } public static bool enericFunction2<T>(T a1, T a2) where T : class { return a1==a2; } } Now when I call both generic functions, one succeeds and one fails: var a = new CustomClass("same value"); var b = new CustomClass("same value"); Debug.Assert(G.enericFunction1(a, b)); // Succeeds Debug.Assert(G.enericFunction2(a, b)); // Fails Apparently, G.enericFunction2 executes the default operator== implementation instead of my override. Can anybody explain why this happens?

  • regular expression - function body extracting

    - by Altariste
    Hi, In Python script,for every method definition in some C++ code of the form: return_value ClassName::MethodName(args) {MehodBody} ,I need to extract three parts: the class name, the method name and the method body for further processing. Finding and extracting the ClassName and MethodName is easy, but is there any simple way to extract the body of the method? With all possible '{' and '}' inside it? Or are regexes unsuitable for such task?

  • Using java provided parameters into xpath function while applying xslt transformation

    - by filmac
    I'm working at a java application that performs some xslt transformation. I would like to match nodes into the xslt document, using a parameter provided by java. Which is the right way to do something like: <xsl:template match="//m:properties/*[contains($pattern,name())]"> because when I launch my application, it claims it's not able to compile the stylesheet, since pattern is not defined but I'm setting it using the setParameter method and I was able to use another parameter defined in the same way but in a different context. Thanks in advance Fil

  • How to create an after_save callback on runtime

    - by dorelal
    I am using ruby on rails 2.3.5 . I have user instance. On run time depending on certain conditions I want to add an after_save callback just for this instance. The other issue is that this after_save should take a block or a proc as parameter. What I want is something like this. This is psuedo code. user = User.first proc = Proc.new do puts 'this is foo' end user.after_save proc

  • Determining where a function is defined in C#?

    - by templatetypedef
    Hey all - I am a complete novice at C# (I've never used it before) and recently needed to look over some code written in it. I spent the longest time trying to track down a nonexistent method in a class that didn't seem to be defined anywhere in the class that was using it. I later found out it was an "extension method," which I gather is a method grafted onto another class by some source. I completely understand the rationale behind this language feature and actually think it's quite nice. However, as someone without much experience in the language, it makes it harder to look up unfamiliar methods, since the method in question could be defined anywhere. My question is this: given an unfamiliar method call in C#, what's the best way for me to look up more info on it, given that it could be an extension method defined in an entirely separate class? Thanks!

  • How to create animated sliding windows/tabs menu?

    - by Forte
    I have created navigation menu in YUI 2.8 as below : I have also animated tabs using CSS transitions. CSS transitions are not widely supported by browsers and my animations are not working in Opera, IE etc. Since i'm already using YUI 2.8 on that page, can somebody tell me how do i animate those tabs? When i click on any tab, it should expand in vertical dimension smoothly (animated). Below are the properties of tabs which are going to change when i select any tab (Below properties of tabs should be animated) : Paddings Margins Background-Color Borders Please note in above image : There is little space left on right side in case #1 when 1st tab is selected. In case #2 and case #3 there is space left on left as well as right side. In case #4, there is some space left on left side when last tab is selected.

  • Using a .delay() function before .css() manipulation in jQuery

    - by Fabian
    I have this: var $ul = $(this).children("ul"); $ul.animate({opacity: 0}, 1000); $ul.delay(1000).css("display", "none") It's for my dropdown menu, and I want it to fade off before it disappears using the display: none; CSS property. However it appears that the .delay() cannot be used on the .css(); it doesn't work, the $ul just disappears right away. I can't use $ul.animate({opacity: 0, display: "none"}, 1000); either.

  • c# performance- create font

    - by user85917
    I have performance issues in this code segment which I think is caused by the "new Font". Will it be faster if fonts are static/global ? if (row.StartsWith(TILD_BEGIN)) { rtbTrace.SelectionColor = Color.Maroon; rtbTrace.SelectionFont = new Font(myFont, (float)8.25, FontStyle.Regular); if (row.StartsWith(BEGIN) ) rtbTrace.AppendText(Environment.NewLine + row + Environment.NewLine); else rtbTrace.AppendText(Environment.NewLine + row.Substring(1) + Environment.NewLine); continue; } if (row.StartsWith(EXCL_BEGIN)) { -- similar block } if (row.StartsWith(DLR_BEGIN)) { -- similar block } . . .

  • wp trim function

    - by Juliver Galleto
    Ok i have this code currently. <?php query_posts('category_name=widgets2'); echo "<div id='widgets-wrapper2'><div id='marginwidgets' style='overflow: auto; max- width: 100%; height: 450px; max-height: 100%; margin: 0 auto;'>"; while (have_posts()) : the_post(); echo "<div class='thewidgets2'>"; echo wp_trim_words( the_content(), $num_words = 0, $more = "..." ); echo '<div style="height: 20px;"></div><a class="button2" href="'.get_permalink().'">Read More</a></div>'; endwhile; echo "</div></div>"; ?> as you can see, it gets all the post from the category name widgets2 and then it should display it. and this line echo wp_trim_words( the_content(), $num_words = 100, $more = "..." ); should trim the words from the_content() to 100 and add a excerpt at the end character but unfortunately it doesnt work, instead it just display the entire contents that looks untrim at all. Hope someone here could figured out. Im open in any suggestions, recommendations and all relevant ideas, thank you.

  • Problems with sys.stdout.write() with time.sleep() in a function

    - by philipjkim
    What I wanted is printing out 5 dots that a dot printed per a second using time.sleep(), but the result was 5 dots were printed at once after 5 seconds delay. Tried both print and sys.stdout.write, same result. Thanks for any advices. import time import sys def wait_for(n): """Wait for {n} seconds. {n} should be an integer greater than 0.""" if not isinstance(n, int): print 'n in wait_for(n) should be an integer.' return elif n < 1: print 'n in wait_for(n) should be greater than 0.' return for i in range(0, n): sys.stdout.write('.') time.sleep(1) sys.stdout.write('\n') def main(): wait_for(5) # FIXME: doesn't work as expected if __name__ == '__main__': try: main() except KeyboardInterrupt: print '\nAborted.'
