His example explains everything I believe.

This code

pawn Код:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    if (dialogid == 1)
    {
        if (response)
        {
            SendClientMessageToAll(-1, inputtext);
        }
        else SendClientMessage(playerid, -1, "You've canceled the dialog.");
    }
    return 1;
}

ShowPlayerDialog(playerid, 1, DIALOG_STYLE_INPUT, "Announce", "Enter your message below.", "Announce", "Cancel");

Becomes

pawn Код:

Dialog:Test(playerid, response, listitem, inputtext[])
{
    if (response)
    {
        SendClientMessageToAll(-1, inputtext);
    }
    else SendClientMessage(playerid, -1, "You've canceled the dialog.");
    return 1;
}

ShowDialog(playerid, Show:Test, DIALOG_STYLE_INPUT, "Announce", "Enter your message below.", "Announce", "Cancel");
