Can I do something like this :

extern (Windows) LRESULT delegate (HWND hWnd, UINT message, WPARAM wParam,
LPARAM lParam) MyWinProcDelegate;

this() {
        MyWinProcDelegate =&Events;
}

extern (Windows) LRESULT Events (HWND hWnd, UINT message, WPARAM wParam,
LPARAM lParam) {
        MessageBoxA(null , "Success!!!" , null ,0);
        return DefWindowProcA(hWnd, message, wParam, lParam);
}

The Events() doesn't seem to fire... am I missing something ?

ok next try, this works for me.

import std.stdio;
import std.functional;

int main(string[] argv)
{
        

        extern(Windows) int delegate( int i) dg;
        alias dg callback;

                        
                        callback = toDelegate(&test);

                        writeln( callback( 1 ) );
                        
                        readln();


return 0;
}

extern(Windows) int test(int i) { return 41 +i;}
