Using vc6.0, from local TXT read data such as "1512 D1 16", have the functions by cstrings read TXT, and archived in the vector, and will send a delete a vector, the effect of want to achieve is to "1512 16 D1" according to the 15 December 16 D1 to send, the problems are the result of sending is 5 1 2 1 6 D 1 these corresponding ASCII characters, such as 1 into 31, etc., is a great god, and how to realize the function, sample code, forget is a great god glad to everyone

You this is not right? Reading is 31 char '1' is not yao write read according to the char into TXT file is not 1

What is your definition of vector type?

Fyi:

By strtol method

Vector is a BYTE type, and then sent into CBytearray, the problem is the vector of each element is 1 5 1 2 one by one, then sent to the board and then read it out is 31 to 35
31 and 32 such values, in the hope that the effect of sending 12 such hair is 15, then reads to verify 15 12 such
