最近在做一个“车辆租赁管理系统”，遇到了一个超出了我能力范围的难题：写卡读卡。目标要求：通过“D8非接触式读写器”工具，1、对M1卡进行车辆信息录入（就两条信息，1，车牌号；2，租用开始时间）；2、对M1卡上的车辆信息读取出来。目前我已经按照狐表帮助文档上那个“连接第三方设备”上的内容导入了相应的DLL文件，并写好了全局代码：

Declare Function add_s Lib "dcrf32.dll" (ByVal i%) As Integer

Declare Function dc_init Lib "dcrf32.dll" (ByVal port%, ByVal baud As Long) As Long
Declare Function dc_exit Lib "dcrf32.dll" (ByVal icdev As Long) As Integer
Declare Function dc_request Lib "dcrf32.dll" (ByVal icdev As Long, ByVal mode%, tagtype As Long) As Integer
Declare Function dc_anticoll Lib "dcrf32.dll" (ByVal icdev As Long, ByVal bcnt%, snr As Long) As Integer
Declare Function dc_select Lib "dcrf32.dll" (ByVal icdev As Long, ByVal snr As Long, size As Byte) As Integer
Declare Function dc_card Lib "dcrf32.dll" (ByVal icdev As Long, ByVal mode%, snr As Long) As Integer
Declare Function dc_load_key Lib "dcrf32.dll" (ByVal icdev As Long, ByVal mode%, ByVal secnr%, ByRef nkey As Byte) As Integer
Declare Function dc_load_key_hex Lib "dcrf32.dll" (ByVal icdev As Long, ByVal mode%, ByVal secnr%, ByVal nkey As String) As Integer
Declare Function dc_authentication Lib "dcrf32.dll" (ByVal icdev As Long, ByVal mode%, ByVal scenr%) As Integer
Declare Function dc_read Lib "dcrf32.dll" (ByVal icdev As Long, ByVal adr%, ByVal sdata$) As Integer
Declare Function dc_read_hex Lib "dcrf32.dll" (ByVal icdev As Long, ByVal adr%, ByVal sdata$) As Integer
Declare Function dc_write Lib "dcrf32.dll" (ByVal icdev As Long, ByVal adr%, ByVal sdata$) As Integer
Declare Function dc_write_hex Lib "dcrf32.dll" (ByVal icdev As Long, ByVal adr%, ByVal sdata$) As Integer
Declare Function dc_changeb3 Lib "dcrf32.dll" (ByVal adr As Long, ByVal secer As Integer, ByRef KeyA As Byte, ByVal B0 As Integer, ByVal B1 As Integer, ByVal B2 As Integer, ByVal B3 As Integer, ByVal Bk As Integer, ByRef KeyB As Byte) As Integer
Declare Function dc_read_allhex Lib "dcrf32.dll" (ByVal icdev As Long, ByVal sdata$) As Integer
Declare Function dc_write_allhex Lib "dcrf32.dll" (ByVal icdev As Long, ByVal sdata$) As Integer
Declare Function dc_set_autoflag Lib "dcrf32.dll" (ByVal icdev As Long, ByVal flag%) As Integer
Declare Function dc_check_writehex Lib "dcrf32.dll" (ByVal icdev As Long, ByVal cardid As Long, ByVal mode As Integer, ByVal adr%, ByVal sdata$) As Integer
Declare Function dc_beep Lib "dcrf32.dll" (ByVal icdev As Long, ByVal time1 As Integer) As Integer

 

但由于我所使用的第三方设备没有狐表帮助文档上那个设备强大，我这边还需要自己定义一个write方法和一个read方法。可能是因为我智商不够用，或者是因为狐表对于第三方设备的例子和讲解太少的原因，我一直无法完成这个系统，对于一个购买了开发版的用户来说，我很悲剧，遇到问题问客服QQ，得到的答案还是帮助文档链接！所以特此发帖求助。究竟我该怎么写这个write和read方法，在哪里写？怎么调用？！
