再缩小一小范围吧!在下面函数中,hDevice是打开哪个文件的句柄(SCSI0?ScsiSN PhysicalDrive0?),dwdwIoControlCode的值是多少?是哪个常量?)才能获得硬盘中包含序列号的信息? DeviceIoControl( HANDLE hDevice, // handle to a device, file, or directory DWORD dwIoControlCode, // control code of operation to perform LPVOID lpInBuffer, // pointer to buffer to supply input data DWORD nInBufferSize, // size, in bytes, of input buffer LPVOID lpOutBuffer, // pointer to buffer to receive output data DWORD nOutBufferSize, // size, in bytes, of output buffer LPDWORD lpBytesReturned, // pointer to variable to receive byte count LPOVERLAPPED lpOverlapped // pointer to structure for asynchronous operation );
这个程序我看不懂,谁有时间将它变为VC的代码? {$APPTYPE CONSOLE}
