To use label to display variable text, it is usually my practice to input the longest text to the label, such as "XXXXXXX ... ", say 20 char. Then define global constant in the header file: #define PRICE_LABEL_LEN 20
And initialize the label just after "FrmInitForm" and before FrmDrawForm, with your initial value, say "$0.00". Every time during change of control label, use StrNCopy() with PRICE_LABEL_LEN to limit the string length. It is dangerous to copy longer string by accident and that would cause crash easily.
