4. Zahlen einlesen

Zahlen einlesen

  • ?

    Hallo!
    Ich möchte mich erstmal bei denen bedangen die mir bisher geholfen haben.
    Ich wollte einen kleinen minnitaschenrechner programmieren ich weiss wie man knöpfe erstellt wie man textfelder erstellt und wie man von textfelder text einliest und ich wollte mal fragen wie man float zahlen einlesen kann und mit welcher formel man die zahlen dan plusnehmen kann oder malnehmen kann.
    danke auf alle antworten.
    MFG MARCUS 🙂 😃

Hallo!
Ich hab es jetzt schohn den ganzen tag versucht aber das funktioniert
nicht so wie ich das will allso ich hab ein minitaschenrechner
programmiert in dem programm unten ist aber jetzt blos
die + funktion programmiert aber die funktioniert nicht
ich weiss zwar wie man texte speichern kann aber nicht wie
man zahlen speichern kann und wie man dann diese 
wieder ausgibt und die zahlen sollen multipliziert werden und dann erst
ausgegeben werden.

    Sowas darfst du nicht machen:

    float zahl;
SendMessage(edit1,WM_GETTEXT,z+1,(long)&zahl);

    weil es soll ein pointer auf eine Zeichenkette sein und nicht auf eine float variable. => schau in MSDN die Parameter von WM_GETTEXT
