exe文件完整性自校验,利用内存流读入自身exe文件PE头部空白处的四个字节,程序编译后需要用winhex软件将CRC值写入PE头部,exe file integrity self-checking, use the memory stream to read its own exe file PE header of four bytes of space, the program compiled the software will need to use winhex to write P

在vb中进行crc校验,程序未经过测试,估计可能有点问题,仅供参考(CRC check, in vb procedure not tested, estimates that might be a little problem, only for reference)
