Question: I wonder if you can **load a DLL**, of Windows operating system (for example, user32.dll), in an **application** (in any programming language) with a **Linux** operating system.

The DLL would be in a directory on the Linux file system.

Thanks for the help.

Greetings!

Answer: 
You could probably do a custom Wine build ([home page](http://www.winehq.org/), [Wikipedia page](http://en.wikipedia.org/wiki/Wine_%28software%29)) for your application. We're talking about a **big** hammer here, though. :-)
Why do you want to do this? To execute a program (`.exe`) that uses that DLL? In that case you need a Windows emulator on your Linux machine, such as [wine](http://www.winehq.org/).
