Weil ich verlier da immer bissle den Überblick... also muss ich da was ändern , oder mich an den langen Code gewöhnen??

MfG Lorun

Oben 5 Buttons : "Restart" "Beenden" "Quadratische Gleichungen" "Taschenrechner" "Parabeln" die zu "Unterprogrammen" führen ( sprich was anderes "malen" ) in den "unterprogrammen" nochmal jeweils 2-3 buttons / editboxes.

Und eben für jedes "Unterprogramm" den Code, der beschreibt, was es tun soll.

Also denk ich mal , das dass normal ist^^

Und kannst du mir sagen, wie ich so ne art "Checkbox" machen kann?

MfG Lorun

Also für das alles ist die Sourcelänge normal, ja.

^^ so sehen meine DEfinitionen und meine Abfrage aus... geht dass so oder muss ich da was komplett anders machen?

[EDIT]Mein Fehler, tschuldigung[/EDIT]

Statt char - TCHAR und wenn Du Texte schreibst, setze das TEXT-Makro davor, also: TCHAR szTest[] = TEXT ( "Mein Test fuer heute" );

Damit gehst Du ganz sicher, das Dein Quellcode Unicodevorbereitet ist.
