Another way is to add this to your code:

```D
pragma(lib, "User32");
```


Oh thank you. I didn't knew that, I thought that it only works in 
visual studio.
Comrades, I need to use inet_ntop() from Ws2tcpip.h, but how I 
gonna include this header file to my code file?

I think it is as simple as adding user32.lib to dmd (directly).


LOL! WTF?!? It works! Thanks Sensei.

Reference to an unresolved external symbol

Hi guys, I have an issue when I compile program with using 
windows api, I got this message:
"reference to an unresolved external symbol _MessageBoxW@16". I 
just created simple hello world using winapi and MessageBox.


import core.runtime;
import std.stdio;
import std.string;
import core.sys.windows.windows;

extern(Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
LPSTR cmdLine, int nCmdShow) {

int result;

try {
Runtime.initialize();
result = myWinMain(hInstance, hPrevInstance, cmdLine, 
nCmdShow);

Runtime.terminate();
} catch (Throwable e) {
result = 0;
}

return result;
}

int myWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
LPSTR cmdLine, int nCmdShow) {

MessageBox(null, "Hello", "D!", MB_OK);

return 0;
}
