I`m using this
On Top of your script:

pawn Код:

new LongMSGBox[1024];

OnGameModeInit/OnFilterScriptInit:

pawn Код:

SetUpLongMSGBox();

Somewhere in your script:

pawn Код:

SetUpLongMSGBox()
{
    LongMSGBox = "Bla Bla Bla Bla Bla Bla Bla Bla Bla Bla Bla Bla\nBla Bla Bla Bla Bla Bla Bla :D :D :D";
    return 1;
}

Dialog:

pawn Код:

ShowPlayerDialog(playerid, 1, DIALOG_STYLE_MSGBOX, "Title" ,LongMSGBox, "button 1", "button2");
