There's two possible problems: one, you don't allocate enough memory for the
buffer for StrPrintF, or two, you dispose of it too quickly.
I use the following code in Codewarrior a decent amount for error checking. The
important thing to note is the buffer must be the maximum size that StrPrintF
can form from your operation plus one for the terminator.
{
char *str=new char[5];
StrPrintF(str, "%x", (Int16) var);
Warning(str); //custom dialog box
delete [] str;
}
