großes problem mit eingaberoutine

Hallo,
ich habe einen Zeiger (char *playername)!
Wenn ich jetzt die Taste 'A' drücke, soll *playername gleich "A" sein.
Wenn ich jetzt noch 'B' drücke, soll *playername gleich "AB" sein.

und wenn ich die BackSpace drücke, soll das letzte Zeichen gelöscht werden.

wie bekomme ich das hin?

Ich hab mal was in der Richtung für Console gemacht... ob es sinnvoll ist oder nicht, darüber kann man sich sicher streiten^^

Mit Capslock das klappt übrigens noch nicht so richtig :roll:
Was deiner Frage entspricht ist _Keycontrol::Instance().GetString(dein_std::string)
