VC 中怎么获取并口地址值

在VC中通过什么函数返回并口地址
LPT1 LPT2 LPT3的地址值
因为每个地址值都可以通过系统改变，所以想返回地址值

用这个试试
unsigned long Num_Transfered;
OVERLAPPED overlapped;
unsigned char Signal = 0;
unsigned char Read = 0;
HANDLE hPort;

overlapped.Internal = 0;
overlapped.InternalHigh = 0;
overlapped.Offset = 0;
overlapped.OffsetHigh = 0;
overlapped.hEvent = NULL;

hPort = CreateFile( "LPT1", GENERIC_READ|GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL|FILE_FLAG_OVERLAPPED, NULL );

还有，这里有一些VC操作并口的例子，希望对你的工作有帮助。http://www.xmwufu.com/admin/SouthidcEditor/Include/3894245-4137.html
