No code at this line number (CV1023) An attempt was made to set a breakpoint at a line that does not correspond to machine code. Such a line could be a blank line, a comment line, a line with program declarations, or a line moved or removed by compiler optimization. To set a breakpoint at a line deleted by the optimizer, recompile the program with the /Od option to turn optimization off. Note that in a multiline statement the code is associated only with one line of the statement. -♦-
