VC++ 改动VMware BIOSuuid_locationethernet0_address等

Posted 2020-10-02 cynchanpin

VC++ 改动VMware Bios、uuid_location、ethernet0_address等。主要问题例如以下

(1)随机产生16进制数。

(2)改动vmx相应项。依据规则一般仅仅改动最后三项值；

摘要：产生十六进制随机数串。比如 "0C 8B 9A"或"0C:8B:9A"
返回值：返回生成随机数串。格式如"0C 8B 9A"或"0C:8B:9A"

void Random(char *szRand,BOOL isMacAddr)
{   
srand((unsigned)time(NULL));
if (!isMacAddr)
sprintf(szRand, "%02x %02x %02x", rand() & 0xFF, rand() & 0xFF, rand() & 0xFF);
else
sprintf(szRand, "%02X:%02X:%02X", rand() & 0xFF, rand() & 0xFF, rand() & 0xFF);


szRand[8] = ‘"‘;
}
