I was under the impression it stood for extended, as in a more detailed interface for that particular library. 

For example, CreateFile with 4 parameters is the typical version and CreateFileEx with 17 is the version offering more control and finer detail over how the file is opened, what occurs if it doesn&#39;t exist, etc, and is thus extended.

When Microsoft updates a function and the new function is incompatible with the old one, Microsoft continues to support the old function. The new function keeps the same name as the old function, with added -Ex suffix.

Since I believe that **64bit** Delphi compiler will appear soon,
I am curious if anybody knows what kind of programs
that are now **32bit** will compile and work without any changes
when using **64bit** compiler.

And if there is a general rule what kind of changes should we 
systematically make in our old programs to be compiled
as **64bit**?

It is good to be prepared when the  **64bit** compiler will suddenly be here...

Any suggestion will be much appreciated. 
 



How should I prepare my 32-bit Delphi programs for an eventual 64-bit compiler?

I&#39;m trying to create a table where each row is a form. I want that each input is in a different table division, but I still need that for example, all first inputs belong to the same table head and so on.

**What I&#39;m trying to do is an editable grid**, more or less this:

    &lt;table&gt;
        &lt;tr&gt;
            &lt;form method=&quot;POST&quot; action=&quot;whatever&quot;&gt;
                &lt;td&gt;&lt;input type=&quot;text&quot;/&gt;&lt;/td&gt;
                &lt;td&gt;&lt;input type=&quot;text&quot;/&gt;&lt;/td&gt;
            &lt;/form&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;form method=&quot;POST&quot; action=&quot;whatever&quot;&gt;
                &lt;td&gt;&lt;input type=&quot;text&quot;/&gt;&lt;/td&gt;
                &lt;td&gt;&lt;input type=&quot;text&quot;/&gt;&lt;/td&gt;
            &lt;/form&gt;
        &lt;/tr&gt;
    &lt;/table&gt;

But apparently I cannot arrange the tags in that way (or so is what the w3c validator said).

Any good way to do this?

**In windows APIs and various other libraries where I have seen multiple entry points to methods I have noticed the use of the Ex abbreviation in scenarios such as MyApiCall and MyApiCallEx.**

My assumption is that this stands for Extension or Extra could someone please confirm?

Any history on why Ex was chosen rather then MyApiCall2 or similar would also be appreciated.

Rendering contexts usually have a solid color on the background (black or whatever, see the image below):

![alt text][1]

I&#39;m wondering if it&#39;s possible to setup a window, with no decorations AND with the transparent background, while allowing me to render OpenGL stuff on it.

This would give the illusion that the triangle is floating on the screen. The transparent background should allow you to see the desktop or other applications that might be behind it.

Could you please exemplify with source code?

After a few years coding in C++, I was recently offered a job coding in C, in the embedded field.

Putting aside the question of whether it&#39;s right or wrong to dismiss C++ in the embedded field, there are some features/idioms in C++ I would miss a lot. Just to name a few:

 - Generic, type-safe data structures (using templates).
 - RAII. Especially in functions with multiple return points, e.g. not having to remember to release the mutex on each return point.
 - Destructors in general. I.e. you write a d&#39;tor once for MyClass, then if a MyClass instance is a member of MyOtherClass, MyOtherClass doesn&#39;t have to explicitly deinitialize the MyClass instance - its d&#39;tor is called automatically.
 - Namespaces.

What are your experiences moving from C++ to C?  
What C substitutes did you find for your favorite C++ features/idioms? Did you discover any C features you wish C++ had?

How can I tell GCC to unroll a particular loop?
I have used the CUDA SDK where loops can be unrolled manually using `#pragma unroll`. Is there a similar feature for gcc? I googled a bit but could not find anything.

Is there any way to use a `sizeof` in a preprocessor macro?

For example, there have been a ton of situations over the years in which I wanted to do something like:

    #if sizeof(someThing) != PAGE_SIZE
    #error Data structure doesn&#39;t match page size
    #endif

The exact thing I&#39;m checking here is completely made up - the point is, I often like to put in these types of (size or alignment) compile-time checks to guard against someone modifying a data-structure which could misalign or re-size things which would break them.

Needless to say - I don&#39;t appear to be able to use a `sizeof` in the manner described above.

In a DOS window, how can I get the full DOS name/short name of the directory I am in?

For example, if I am in the directory `C:\Program Files\Java\jdk1.6.0_22`, I want to display it&#39;s short name `C:\PROGRA~1\Java\JDK16~1.0_2`.

I know running `dir /x` will give me the short names of files/directories in the current directory but I haven&#39;t been able to find a way to display the full path of the current directory in short name format. I&#39;m having to work my way through the path from the root, directory by directory, running `dir /x` in each.

I&#39;m sure there is an easier way to do this?

How do I check if the current batch script has admin rights?

I got some folders created by malware whose name ended with a dot like `C:\a.\` or `C:\b.\`, etc.

I found a solution that can remove such folder with command `rd /q /s &quot;C:\a.\&quot;` but if I call win API [`RemoveDirectory`][1], it returns `ERROR_FILE_NOT_FOUND`.

And I just wonder how to write a function to delete such directory, thanks

I test on my own Windows XP SP3 system like this

create a folder `C:\&gt;mkdir a..\\\` and I cannot double click to access this folder. and I can remove with command  `rd /q /s &quot;C:\a.\&quot;`

what Windows system API(s) that `rd /q /s` command call?

Greetings,
I&#39;ve been toying with an idea for a new project and was wondering if anyone has any idea on how a service like Kayak.com is able to aggregate data from so many sources so quickly and accurately. More specifically, do you think Kayak.com is interacting with APIs or are they crawling/scraping airline and hotel websites in order to fulfill user requests? I know there isn&#39;t one right answer for this sort of thing but I&#39;m curious to know what others think would be a good way to go about this. If it helps, pretend you are going to create kayak.com tomorrow ... where is your data coming from?

I&#39;m currently creating an authentication system on front of a public web API for a web application. Given that each user account has an API key and each request must be authenticated, I have two alternatives:

1. Using an HTTP Basic Authentication, [like GitHub does][1].

    Requests must be sent to the URL

        http://api.example.com/resource/id
        with basic authentication
        username: token
        password: the api key

2. Passing the API Token as querystring parameter.

    Requests must be sent to the URL

        http://api.example.com/resource/id?token=api_key

There&#39;s also a third option which is passing the token within the URI, but I honestly don&#39;t like that solution.

Which solution would you adopt and why?

Does anyone know what happened to the `path.exists()` API method in the latest Java 7 API? 
I cannot find the change in the change logs, and between b123 and b130, the method has been removed from the API.I see that there is a static `Files.exists` method but I&#39;m not sure if that is the replacement or not. 

Is anyone following the Java 7 work close enough to know how this should be handled?

Thanks for any help.

Apologies if this has already been asked and answered; I&#39;ve looked around a bunch but haven&#39;t found exactly what I&#39;m asking.

1. Suppose my web app at http://example.com/ uses a private and undocumented web API at http://api.example.com/ to fetch data, e.g. via XHR or JSONP.

2. Also suppose that this web app is anonymous &amp;mdash; it does *not* require user login.

3. Since there&#39;s communication between client and server, anyone can open Fiddler, etc. to see the exact request and response, not to mention inspect the client-side JS code.

In a case like this, how can you prevent someone from using your API in a **_non-web_** client app? E.g. an iPhone app, or server-side.

To my understanding, point #2 removes the option of something like OAuth, and point #3 removes the option of e.g. API keys or even SSL.

I&#39;ve thought about things like time-based tokens or secret salts that are injected into the page on first load, but an iPhone app could easily just secretly load your webpage before making API requests.

So is there any way besides just plain obfuscation &amp;mdash; security through obscurity?

--

In case all that is too abstract, here&#39;s a simple example:

Google.com fetches its auto-complete data via some API that&#39;s private and undocumented &amp;mdash; but open on the web. What&#39;s to stop me from using it in my iPhone app?

I am a Delphi programmer and have written, over the years, hundreds of classes and routines which I can use in every Delphi program I write.

This **library** is called dlib and can be **used in every Delphi program** by putting this folder in my library path and using one of the units in the uses section of a Delphi unit.

Being completely new to Java and Android development, I am wondering how to do this in similar way.

**So my question, how can I write own classes, put them in some global folder, and use these classes and routines in every Android program I write** ?

I know this is a basic question, which I can probably find out by searching Google and trying it out in Eclipse, but if someone can put me on the right track, I know I will save much time.

Thanks.

I know that global variables are bad.

But if I am using node&#39;s module &quot;util&quot; in 40 files in my framework, isn&#39;t it better to just declare it as a global variable like:

    util = require(&#39;util&#39;);

in the index.js file instead of writing that line in 40 files?

Cause I often use the same 5-10 modules in each file, that would save a lot of time instead of copy paste all the time.

Isn&#39;t DRY good in this case?
