AlliedModders - Say Commands

I know how to notice if a player says something, but I want
that if a player says a specific word that something happens.
I got this now:

Code:

if (  FStrEq( pcmd, "say" ) ) 

        {

            IPlayerInfo* playerInfo;

            playerInfo = playerinfomanager->GetPlayerInfo(pEntity);

                 

            KeyValues *kv = new KeyValues( "msg" );

            kv->SetString( "title",  playerInfo->GetName());

            kv->SetInt( "level", 1 );

            kv->SetInt( "time", 20 );

                

           helpers->CreateMessage( pEntity, DIALOG_MSG, kv, this );

           kv->deleteThis();

           return PLUGIN_STOP; 

        }

I want that if a player says: "myname" that his name will be displayed in a messagebox.

This is just for understanding and lerning.
Maybe I'll write a rollthedice plugin.
