参考代码如下: RandomAccessFilefile=newRandomAccessFile("file.txt","r");byte[]bytes=newbyte[(int)file.length()];file.readFully(bytes);Stringcontent=newString(bytes,"UTF-8");if(content.contains("char")){Stringresult=newString(bytes,"UTF-8");System.out.println(result);}file.close(); 1....
JDBC 是一个数据访问层,它允许 Java 与基础数据源交互。JDBC-ODBC 桥是一个数据库驱动程序实现,它依赖 ODBC 驱动程序才能连接至 Access 数据库。驱动程序将 JDBC 方法调用转化为 ODBC 函数调用。 private static String strConnect = "jdbc:odbc:DRIVER=Microsoft Access Driver (*.mdb, *.accdb);DBQ=C:\\Nor...

Note that although the methodgetStringis recommended for retrieving the SQL typesCHARandVARCHAR, it is possible to retrieve any of the basic SQL types with it. Getting all values withgetStringcan be very useful, but it also has its limitations. For instance, if it is used to retrieve a nu...

因为一开始没有太理解C++中的指针,所以BYTE*我尝试过很多类型,包括char[] 、String 、byte[],结果都不行,后来使用Memory 来分配一段连续的地址,就类似C语言中的malloc函数。 这个问题倒是解决了,还有个问题是UINT*类型,我一开始想,直接给个int,应该也没啥问题,后来发现,不得行,还是的使用int指针,JNA提供了Int...
