    Using Data In different forms

    In my form FMain, I use values given in the Edits to do some calculations on button click. I need to use the results of some of these calculations on another form. So should I do it like: class Main : public TFMain { public: Alfa1; //The result of a calculation done in FMain }

    Only numbers in the edit box

    Is there a way that the user is only able to put numbers in an Edit box? I tried to program so that a warning would be sent if a letter was typed but i couldnt manage. Would have to do too many comparisons and there are too many edit boxes. Any body can help?
