d窗口编程第一篇.

import core.runtime;
import std.utf;
import core.sys.windows.windows;

extern (Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int iCmdShow)
{
    int result;
    try
    {
        Runtime.initialize();
        result = myWinMain(hInstance, hPrevInstance, lpCmdLine, iCmdShow);
        Runtime.terminate();
    }
    catch (Throwable o)
    {
        MessageBox(null, o.toString().toUTF16z, "Error", MB_OK | MB_ICONEXCLAMATION);
        result = 0;
    }

    return result;
}

int myWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int iCmdShow)
{
    MessageBox(NULL, "Hello, Windows!", "Your Application", 0);
    return 0;
}

再简化:

import core.runtime;
import std.utf;

import core.sys.windows.windows;

void main()
{
    MessageBox(null, "Hello, Windows!", "Your Application", 0);
}
