我正在与门禁控制和考勤机连接 我发现这个项目在github中使用java连接到相同类型 但在我想设置CardNumber属性的行中,我有一个例外 “ com.jacob.com.ComFailException:无法将名称映射为dispid:CardNumber [0]” 有人可以帮我

https://github.com/lookskystar/ZKKQProject/blob/master/ZKKQProject/src/com/zkkq/uitl/ZkemSDK.java

public class ZkemSDK 
{
    private static ActiveXComponent zkem ;

    public   ZkemSDK(){

        zkem = new ActiveXComponent("zkemkeeper.ZKEM.1");
        System.out.println("done ");
    }
    public boolean connect(String address,int port, int machineNum) throws Exception{

        boolean result = zkem.invoke("Connect_NET",address,port).getBoolean();
    }

    public boolean SetUserInfo(int machineNum,int enrollNo2,String userName,String password,int privelage ,boolean flag) {

        Variant dwUserName = new Variant(userName,true);
        Variant dwPassword = new Variant(password,true);
        Variant dwPrivelage = new Variant(privelage,true);
        Variant dwEnrollNo = new Variant(enrollNo2,true);
        Variant dwMachineNum= new Variant(machineNum,true);

        /****/

        zkem.setProperty("CardNumber[0]",454545);
        /****/

        Variant vResult = Dispatch.call(zkem,"SetUserInfo",dwMachineNum, dwEnrollNo, dwUserName, dwPassword, dwPrivelage,true);


        return true;
    }
}

我发现有人可以覆盖setProperty来添加数组 在此链接 setParameter for an array property with JACOB  我的代码就是这个

public static void setProperty(Dispatch d, String sName, String sIndex, String sValue) {
      Variant av[] = { new Variant(sIndex), new Variant(sValue) };
      int j[]= {0};
      Dispatch.invokev(d, sName, Dispatch.Put, av,j).safeRelease();
      av[0].safeRelease(); av[1].safeRelease();
      }

呼叫就像这样

this.setProperty(zkem,"CardNumber","0","2599970");

此行之前

Variant vResult = Dispatch.call(zkem,"SetUserInfo",dwMachineNum, dwEnrollNo, dwUserName, dwPassword, dwPrivelage,true);
