在使用NHibernate时,我花了大部分时间尝试解决此消息:"索引超出范围.必须是非负数且小于集合的大小.参数名称:index"
我的更新和删除工作正常,但调用save()后调用flush不起作用.我不认为发布所有代码(有很多)是有用的,因为我不确定你现在需要看到什么.我正在尝试保存的数据访问对象使用复合键,如果这有帮助的话.另外,我正在使用NHibernate.Mapping.Attributes来创建我的映射.
似乎在我的堆栈跟踪中,NHibernate正在尝试向ADO.Net类发送无效数量的参数以进行插入操作.话虽这么说,我有跟踪设置为true以查看sql语句,但错误是在sql语句被发送到输出之前引发的所以我不确定它正在尝试构建什么..
public void Insert(ProddataDAO Entity)
{
Entity.PSEQ = GetNewSeqID(Entity.PCUST); // <- because I'm using a composite key, this function gets my a unique value by a group
NHibernateHelperCGC.CurrentSession.Save(Entity);
NHibernateHelperCGC.CurrentSession.Flush(); // <-This raises the error
}

<p>After 32 years in its former location, this popular restaurant
and bar moved to the bottom of the Avalon Bay Luxury residential building
that's just a walk from Angel Stadium. Modern and welcoming, the expansive
space is where fans, locals and families gather for upscale twists on classic
American dishes. Burgers here have a decidedly fun flair like “The OMG�
that is a burger surely meant for sharing (with many)--it's so huge that it's
served on a 14-inch bun. …我知道ItextSharp在HTML和CSS解析方面有一些重要的限制.
我正在寻找一些文件或帖子,告诉我这个限制,而不是测试每个可能的功能,并交叉我的手指.
我可以使用哪些CSS样式？怎么表明我这样做？
这同样适用于HTML.今天早上mi应用程序崩溃,因为我正在使用<hr />标签,ItextSharp似乎不支持.
我一直在寻找这样的文件,但我没有找到任何东西.
谢谢.
使用HTML帮助程序,如何在不提交的情况下强制执行数字？如果你在经典ASP.NET中有一个文本框,我知道它是用正则表达式完成的
<%= Html.TextBox("txtYearOfWork",
String.Empty,
new { maxlength = 4, size="5", autocomplete = "off" }) %>
下面的代码会给我一个错误,因为boost :: mutex是不可复制的,而xyz.push_back()是一个复制构造函数.
class XYZ
{
public:
double x;
boost::mutex x_mutex;
}
vector<XYZ> xyz;
xyz.push_back(XYZ());
所以我试过这样的事,
class XYZ
{
public:
double x;
boost::mutex * x_mutex;
}
vector<XYZ> xyz;
xyz.push_back(XYZ());
它没有错误,但问题是"互斥体实际上是否会按原样运行？" 这是在类中封装互斥体,然后创建该类的向量的好方法吗？
谢谢.
在浏览Arrays Class的JavaDocs时.我意识到有很多重载方法.例如,
static int binarySearch(byte[] a, byte key)
static int binarySearch(char[] a, char key)
static <T> int binarySearch(T[] a, T key, Comparator<? super T> c)
我无法理解,为什么需要这么多重载方法,而最后一个通用方法似乎已经足够了.
即使在Generics之前,研究方法Object也可以解决问题.
为什么Arrays类设计有如此多的重载方法？
