The External Dependencies folder is populated by IntelliSense:  the contents of the folder do not affect the build at all (you can in fact disable the folder in the UI).

You need to actually include the header (using a `#include` directive) to use it.  Depending on what that header is, you may also need to add its containing folder to the &quot;Additional Include Directories&quot; property and you may need to add additional libraries and library folders to the linker options; you can set all of these in the project properties (right click the project, select Properties).  You should compare the properties with those of the project that does build to determine what you need to add.

	To resolve external dependencies within project. below things are important..
	1. The compiler should know that where are header &#39;.h&#39; files located in workspace.
	2. The linker able to find all specified  all &#39;.lib&#39; files &amp; there names for current project.

	So, Developer has to specify external dependencies for Project as below..

	1. Select Project in Solution explorer.

	2 . Project Properties -&gt; Configuration Properties -&gt; C/C++ -&gt; General
	specify all header files in &quot;Additional Include Directories&quot;.

	3.  Project Properties -&gt; Configuration Properties -&gt; Linker -&gt; General
	specify relative path for all lib files in &quot;Additional Library Directories&quot;.

I am importing lots of functions from a module

Is it better to use

    from my_module import function1, function2, function3, function4, function5, function6, function7

which is a little messy, but avoids flooding the current namespace with everything from that module or

    from my_module import *

Which looks tidy but will fill the namespace with everything from that module.

Can&#39;t find anything in PEP8 about what the limit for how much you should import by name is. Which is better and why?

I wonder why one of my projects has `VDSERR.h` listed under &quot;External Dependencies&quot; and another hasn&#39;t and gives me an &quot;undefined symbol&quot; compiler error about a symbol which is defined in there. How can I include this file in the other project as well?

I am writing a program for an embedded hardware that only supports 32-bit single-precision floating-point arithmetic. The algorithm I am implementing, however, requires a 64-bit double-precision addition and comparison. I am trying to emulate `double` datatype using a tuple of two `float`s. So a `double d` will be emulated as a `struct` containing the tuple: `(float d.hi, float d.low)`.

The comparison should be straightforward using a lexicographic ordering. The addition however is a bit tricky because I am not sure which base should I use. Should it be `FLT_MAX`? And how can I detect a carry?

How can this be done?

--------------------
*Edit (Clarity):* I need the extra significant digits rather than the extra range.

If I want to define a value only if it is not defined, I do something like this :

    #ifndef THING
    #define THING OTHER_THING
    #endif

What if `THING` is a `typedef`&#39;d identifier, and not defined? I would like to do something like this: 

    #ifntypedef thing_type
    typedef uint32_t thing_type
    #endif

The issue arose because I wanted to check to see if an external library has already defined the `boolean` type, but I&#39;d be open to hearing a more general solution.

In C/C++, is there a directive similar to #ifndef for typedefs?

I have been using &quot;Accelerated C++&quot; to learn C++ over the summer, and there&#39;s a concept which I don&#39;t seem to understand properly.

Why is

    int x;
    if (cin &gt;&gt; x){}

equivalent to

    cin &gt;&gt; x;
    if (cin){}

By looking at the code, it seems to me that we&#39;re using cin as a variable. But, I thought it was a function. Why can we use cin in this way when it is x that has whatever value we input into our keyboard?

if (cin &gt;&gt; x) - Why can you use that condition?

I&#39;ve read about this technique: [Shared assembly info in VS projects - JJameson&#39;s blog](http://www.technologytoolbox.com/blog/jjameson/archive/2009/04/03/shared-assembly-info-in-visual-studio-projects.aspx )

Basically it means to create a SharedAssemblyInfo.cs with versioning information about the assembly, and adding this file as Link to all projects of the solution, so the actual file resides only in 1 location on disk.

My question deals with 2 scenarios:

1. Existing solution that doesn&#39;t use this mechanism: Is there a way to easily add the ShareAssemblyInfo to all projects? (lets say i have a solution with 50 projects).

2. When creating a new project, by default a new AssemblyInfo.cs is created. However i&#39;d like to link automatically to the SharedAssemblyInfo as well.

Is there any solution for this? what is the common practice?

Shared AssemblyInfo for uniform versioning across the solution

not a showstopper but when using nuget in a project, it creates a packages.config file with this shape

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;packages&gt;
       ... your packages
    &lt;/packages&gt; 

this gives a warning in VS 

    The &#39;packages&#39; element is not declared.

The origin of the problem got something to do with the xml declaration I guess.

Also I think that the default definition package shouldn&#39;t throw warnings.

Does anyone know what should I change it to so I don&#39;t get this warning? (ie even if I can see it only when the file is open, it also shows as a warning constantly with certain CA rules on.)

In configuration properties of my project, under the &quot;VC++ directories&quot; there is an entry for &quot;Include Directories&quot;. But under &quot;C/C++&quot; option, there is another entry called &quot;Additional Include Directories&quot;. Same thing happens with library directories.

What are the difference between these two entries?

I have a library and a console application that uses a library. The library has a folder with source and header files.

My project is in a child/inner directory but that library directory that I want to include is in a parent/upper directory.

My project directory:

    H:\Gmail_04\gsasl-1.0\lib\libgsaslMain

Includes files are here:

    H:\Gmail_04\gsasl-1.0\src

How can I use paths relative to the project directory, to include folders that are in a parent/upper directory?

How to define relative paths in Visual Studio Project?

I have a solution in C:\full path here\VS2010\blender.sln

This solution contains many projects(around 100). When I compile them, they all work fine. I can run them without any problem, and (quite) everything works (there are some bugs).
One of the projects is ALL_BUILD, but it gives the same error if I try to debug INSTALL(another project). I&#39;m compiling with RELWithDebInfo as configuration, and if I execute the program manually it works. It is outputted in C:\full path here\VS2010\bin\RelWithDebInfo

But if I try to run the compiler, it says 
&gt; &quot;Unable to start program 
&gt; C:\full path here\VS2010\RelWithDebInfo\ALL_BUILD
&gt;Specified file cannot be found&quot;

I tried to copy the compiled program into the path required by VS, but it raised the same error.

What should I do to solve this? Right now I set up cmake to generate also a mingw project and I compile it and debug it with gdb, but this is a really a slow and impractical workflow, and I would like to use the VS debugger.

I must say that if I compile with Debug as configuration, the program doesn&#39;t even start.

I&#39;m using VS2010 Express on Win7 64bit

(This is a big open source program, so I don&#39;t know exactly whatever it does)

Is there a way to disable just a single warning line in a cpp file with visual studio?

For example, if I catch an exception and don&#39;t handle it, I get error 4101 (unreferenced local variable). Is there a way to ignore this just in that function, but otherwise report it in the compilation unit? At the moment, I put `#pragma warning (disable : 4101)` at the top of the file, but that obviously just turns it off for the whole unit.

*Assuming I am **only** using them for &quot;normal&quot; GUI programs (no COM, no ActiveX, nothing fancy), what is the fundamental difference I will see between ATL and MFC, to help me figure out which one to use?*

------

I&#39;ve done some searches on the web, but ultimately none of the answers really answered my question:

- http://msdn.microsoft.com/en-us/library/bk8ytxz5(v=vs.80).aspx:
	- *&quot;ATL is a fast, easy way to both create a COM component in C++ and maintain a small footprint. Use ATL to create a control if you don&#39;t need all of the built-in functionality that MFC automatically provides.&quot;*
	
		Doesn&#39;t really answer my question, because:
		
		- I&#39;m not working with COM.
		
		- Does this imply MFC *isn&#39;t* fast? Why/how?
 
	- *&quot;MFC allows you to create full applications, ActiveX controls, and active documents. If you have already created a control with MFC, you may want to continue development in MFC. When creating a new control, consider using ATL if you don&#39;t need all of MFC&#39;s built-in functionality.&quot;*

		Also doesn&#39;t answer my question, because:
		- I don&#39;t really even know what ActiveX *is* in the first place.
		
		- It looks as though Microsoft is discouraging the use of MFC, but I can&#39;t figure out why.
		
		- What exactly ***is*** MFC&#39;s &quot;built-in functionality&quot; that ATL doesn&#39;t provide?

	- In general, this doesn&#39;t answer my question because **it doesn&#39;t explain the downsides** and the reasons behind them.

because directly or indirectly, everything seems to link back to the previous page:

- https://stackoverflow.com/questions/821676/how-do-i-decide-whether-to-use-atl-mfc-win32-or-clr-for-a-new-c-project

	- *&quot;ATL &amp; MFC are somewhat trickier to decide between.* [[No kidding!]] *I&#39;d refer you to [MSDN&#39;s page](http://msdn.microsoft.com/en-us/library/bk8ytxz5%28VS.80%29.aspx) for choosing in order to decide between them.&quot;*
	
		*Obviously*, this doesn&#39;t answer my question. :)

- http://www.codeguru.com/forum/archive/index.php/t-64778.html

- etc.

What I have **currently observed** (within the last couple of days, while trying to learn both):

- ATL is based on templates, or compile-time polymorphism.
	- ATL methods tend to be non-virtual, and tend to return references.
- MFC is based on virtual methods, or run-time polymorphism.
	- MFC methods tend to be virtual, and tend to return pointers.

But there *doesn&#39;t seem to be any architectural difference between them*:

- Both use message maps (`BEGIN_MSG_MAP` vs. `BEGIN_MESSAGE_MAP`... big deal)
- Both wrap Win32 methods into classes
- Both seem to have similar classes `CWnd` vs. `CWindow`

But then, if there&#39;s no real difference except for the compile-time vs. run-time aspect, then why do both of them exist? Shouldn&#39;t one of them be enough?

What am I missing here?

What&#39;s the fundamental difference between MFC and ATL?

I&#39;m trying to do something that I believe should be possible, but I really can&#39;t understand how to do it just from the webpack documentation.

I am writing a JavaScript library with several modules that may or not depend on each other. On top of that, jQuery is used by all modules and some of them may need jQuery plugins. This library will then be used on several different websites which may require some or all modules.

Defining the dependencies between my modules was very easy, but defining their third-party dependencies seems to be harder then I expected.

**What I would like to achieve**: for each app I want to have two bundle files one with the necessary third-party dependencies and other with the necessary modules from my library.

**Example**:
Let&#39;s imagine that my library has the following modules:

 - a (requires: jquery, jquery.plugin1)
 - b (requires: jquery, a)
 - c (requires: jquery, jquery.ui, a, b)
 - d (requires: jquery, jquery.plugin2, a)

And I have an app (see it as a unique entry file) that requires modules a, b and c. Webpack for this case should generate the following files:

 - **vendor bundle**: with jquery, jquery.plugin1 and jquery.ui;
 - **website bundle**: with modules a, b and c;

In the end, I would prefer to have jQuery as a global so I don&#39;t need to require it on every single file (I could require it only on the main file, for example). And jQuery plugins would just extend the $ global in case they are required (it is not a problem if they are available to other modules that don&#39;t need them).

Assuming this is possible, what would be an example of a webpack configuration file for this case? I tried several combinations of loaders, externals, and plugins on my configuration file, but I don&#39;t really get what they are doing and which ones should I use. Thank you!
