Win32api: How to send a Struct in DialogBox?

[Marcone]

Solved:

Teste * params = cast(Teste*) lParam;

writeln(params.nome);
writeln(params.idade);


But here, how can send struct?

DialogBoxParam(null, MAKEINTRESOURCE(IDD_DIALOG1), null, 
&DlgMain, cast(int) &test); // Error, need "int" but I am sending 
Test*
