The document:
http://msdn.microsoft.com/en-us/library/dd607349(v=vs.85).aspx
states that #include "foobar.fx" will look for that file in the same directory as the current effect file.
It doesn't work, but using an absolute path does, which is of course useless.
Google doesn't come up with anything. Anything I'm missing here?
There is a default include handler for the Direct3D 11 On-the-fly shader compiler.
It's a macro: (c++)
D3D_COMPILE_STANDARD_FILE_INCLUDE
Here's a link to the D3DCompile function.
http://msdn.microsoft.com/en-us/library/windows/desktop/dd607324(v=vs.85).aspx
The macro is mentioned in the explanation of the include variable.
It took me a while to find with google oddly enough, but I passed here on the way.
I thought I'd post it in case anyone else ends up here.
That automatic handling only works for the offline shader compiler tool, as mentioned in the link you provided. If you're compiling using one of the APIs, you'll need to specify an include handler for the compiler to use whenever it encounters an include directive: ID3DInclude

In Visual Studio Code, F2 rename on purely local C++ symbols is fine, but trying it on a symbol with wider scope, results in a very aggressive scope of suggested renaming, going as far as suggesting to rename unrelated symbols with the same name in the system header files. These typically default to unchecked, but at one point, it did rename an unrelated symbol with the same name in a project header, so it would be nice if the default could be dialed down a bit. Is there a way to do that?
The problem isn't with vscode, it's the linter vscode is using.
The easiest way to try to resolve the problem is using a different more advanced c++ linter. It's what I did to resolve a similar issue using golang.
Maybe the below link will help you find your new favorite linter.
https://www.reddit.com/r/cpp/comments/5b397d/what_c_linter_do_you_use/
PS: There is probably a setting that can edit the linter like what I am posting below, but based off of what you're asking, it may be difficult to find the right regex or whatever you need. It'd probably be best just to switch linters and then maybe make an issue on their github repository if you can't find one that suis your need.

I am looking through the PhantomJS source code and I've encountered this line:
Q_PROPERTY(QString frameName READ frameName)
I don't understand how this is correct syntax, it's even missing a semi-colon.
Here is the fine in question on the Github repo, in case you need to sift through it https://github.com/ariya/phantomjs/blob/master/src/webpage.h
It's a macro that the Qt Library defines to have its own Property System. It uses its own macros mainly because of being platform independent (its aim is not to rely on specific compilers/os). I don't think I can add anything not in their reference docs.
So I've been trying to implement an #if parser into an infobox, but I seem to be out of luck. The previous code I used seems to be outdated, and I can't find the a way to code it in again, differentely. :/
Basically, in this infobox, if a field is not typed in(or if typed in is left empty) it should become 'invisible' or not even render.
This code worked fine in a previous version of MediaWiki(not sure which one though), but no longer: http://pastebin.com/uQ49mPbQ. I've been trying to use it as a tutorial, and even outright copy and pasted it, but it simply doesn't work. All of the fields would become invisible, regardless of what I would have done to them...
This is the new code that I am using, and would like to be #if'ed: http://pastebin.com/3j0AbN5v
Any help would be welcome.
You need to enable the ParserFunctions extension to be able to use the {{#if}} parser function. Do this in your LocalSettings.php:
require_once( "$IP/extensions/ParserFunctions/ParserFunctions.php" );
If you want to use the string functions (like {{#replace}}, {{#explode}}, etc), also add:
$wgPFEnableStringFunctions = true;
In recent versions of MediaWiki, ParserFunctions is included (but not enabled) so you don't need to download anything.
Basic troubleshooting: Whenever you see code like {{#zyx:...}} in a wiki page, it (probably) means, that someone tried to use a parser function that is not installed. Unless there is a parser function called “zyx” installed, the code {{#zyx:...}} has no special meaning to the wiki, and the text will be printed just like it is. The most common parser functions are collected in an extension called ParserFunctions, that is used on WikiMedia wikis. You will need the parser functions from ParserFunctions whenever copying templates from e.g. English Wikipedia.
To see what parser functions you have enabled, navigate to Special:Version on your wiki. Below the list of installed extensions is a list of tags (such as <gallery />) and parser functions available. As you can see, “if” is among the parser functions on your old wiki, but not on your new.
I'm trying to write a function to load a JPEG, and I've downloaded the sample code from MSDN Q218972, but it is using precompiled headers and I am not.
I've spent hours looking for where LPPICTURE and OleLoadPicture() are defined but can't find it anywhere.
Does anyone know which header I need to include for these two?
In future, is there any resource I can use to find this information? MSDN documents the .NET world extremely well and it's often trivial to find what I need to include, but I'm finding that it takes longer to identify headers to include for my Win32 program than to learn how to write a Win32 program!
OleLoadPicture() is defined in OleCtl.h and implemented in OleAut32.dll. The import library is OleAut32.lib.
The information is found towards the bottom of the MSDN topic.
As for LPPICTURE, that is also defined when you include OleCtl.h.
I am currently developing a C++ program that does all the mathematical calculations, prints items to the screen that is scanned in by an RFID Reader, and allows the user to select a payment method. (Basically using RFID tags to replace barcodes)
I have started writing my C++ code for a keyboard entry and have no idea how to take an input from my RFID reader into my program. My RFID Reader is a DLP-RFID1 from it comes with some demo software and drivers. I got it working with windows 7 last week on the demo software(a GUI using Microsoft Visual Studio).
My question is can I take the input from my Demo GUI and some how use that as my input for my C++ program? If I can can some one push me in the right direction by links, pointers, reading material?
Also I have basic C++ experience. I am teaching myself how to program in C++ and right now only know print statements, while loops, switch/case, math functions, and etc.
That is a very specific question about hardware and software of that vendor an not really general knowledge. However, those types of devices, in my past experience with bar code readers and such, usually have a driver that comes with them which allows you to set them up as an actual keyboard (for example, you could even go into a text editor and capture the codes). If you can set them up like that, then reading them is nothing more than reading stdin. For example, cin >> stringVariable;
Assuming that you have demo software in C++:
The demo software should link against one or more libraries that comes with the demo, and include a header that declares the functions in the library. You have to (at minimum) include this header and link against that same library, and use those libraries. The demo will help you understand which functions you need to call and how.
As already said it is very dependent on how they want you to use it but some general guide lines.
Look for header file that came with their demo ( ends in ".h" or ".hpp")
you will need to #include that in your project at the very minimum
Look for a .lib file. you will need to link that to your file. With gcc you would type something like G++ -l[libname].
With MSVS there are two ways i know of. You will need to right click the project in the sidebar. Click something like options or preferences. Expand linker options. Add the library.
or you can type #pragma comment(lib, "filename.lib") in your file near your includes
If there is a .dll (windows) or .so(Linux) file you can dynamically link it. There are many ways to do this. Google search for C++ Dynamic link libraries should be some help. As a newbie try to stick with Static Linking first. that would be another good keyword to search for. The best tutorial on dynamic linking for windows i have found is actually in assembly. but its all Win32 function calls anyways so its not hard to understand. Icz DLL tutorial
