default

Whenever I add a new class to a Visual Studio (C#) project, I get the following usings automatically: using System; using System.Collections.Generic; using System.Linq; using System.Text; Additionally, the following DLL references are added if they weren't there already: System.Core System.Data System.Xml I'd like to prevent VS from doing this (except "using System" of course). Does any one know of a way to prevent this from happening? Marc and Brian both have a good idea: create a new custom template that includes only the usings and references I want. With Export Template it's really simple

Why does Visual Studio 2008 automatically insert the following using directives into each new C# file I create? using System; using System.Collections.Generic; using System.Text; What's so special about these namespaces? Are these the most frequently used ones? Jon Skeet Yes, they're frequently used, that's all, so MS put them in the Visual Studio templates . Personally I use "sort and remove unused usings" pretty frequently, so they often go away. If you want to remove them, you can amend the "new class" template . EDIT: If you become a fan of "Sort and Remove Unused Using Directives" you

Converting a C++ lib to ANSI C and it seems like though ANSI C doesn't support default values for function variables or am I mistaken? What I want is something like int funcName(int foo, bar* = NULL); Also, is function overloading possible in ANSI C? Would need const char* foo_property(foo_t* /* this */, int /* property_number*/); const char* foo_property(foo_t* /* this */, const char* /* key */, int /* iter */); Could of course just name them differently but being used to C++ I kinda used to function overloading. No, Standard C does not support either. Why do you feel you need to convert your

If I have an array full of information, is there any way I can a default for values to be returned if the key doesn't exist? function items() { return array( 'one' => array( 'a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, ), 'two' => array( 'a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, ), 'three' => array( 'a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, ), ); } And in my code $items = items(); echo $items['one']['a']; // 1 But can I have a default value to be returned if I give a key that doesn't exist like, $items = items(); echo $items['four']['a']; // DOESN'T EXIST RETURN DEFAULT OF 99 I know this is an old

What is default storage class of a global variable? While searching on web I found, some sites say it is static . But, static means internal linkage and the variable can not be available outside the file scope i.e it should not be available to other object files. But, they still can be accessed to other files using declarations like extern int i . And, if I explicitly mention static to global variable then it is not available outside the file scope. Then, what is correct default storage class for the global variables? The default storage duration is static, but default linkage is external. You

Possible Duplicate: Changing default encoding of python? I am reading dive in python and it mentions setting python's default encoding scheme in the XML parsing chapter. The setdefaultencoding is used in python-installed-dir/site-packages/pyanaconda/ sitecustomize.py import sys sys.setdefaultencoding('utf-8') But when I run the script, it raises: AttributeError: 'module' object has no attribute 'setdefaultencoding' How to set the default encoding,anyway? I am using python 2.7 Solution: find the site.py in the python installation. Edit the setencoding function def setencoding(): encoding =

I am writing a WPF control that subclasses a Button. I then provide a default style in Themes\generic.xaml, that looks like this (simplified): <Style TargetType="{x:Type WPFControls:MyButton}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type WPFControls:MyButton}"> <Button x:Name="PART_Button" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" /> </ControlTemplate> </Setter.Value> </Setter> </Style> I would like the user to have the opportunity to change the control's background, but if he doesn't, I'd like to provide default

How do I tell STL, specifically for the method resize() in vector, to initialize objects with a constructor other than default, and with which parameters? For example: class something { int a; something (int value); } std::vector<something> many_things; many_things.resize (20); More generally, how do I force STL to use my constructor when it needs to create objects, and pass parameters to that constructor? In my case adding a default constructor is not an option, and I'd prefer not to use an array of pointers to solve the problem. Use the 2-argument overload: many_things.resize(20, something(5
