Build 4.3.15

Multi-Level Horizontal Mapping

New Feature: VOA-1592

Horizontal mapping is restricted to one level at the top of the hierarchy. This enhancement adds the capability to map multiple levels of the hierarchy to one table.

The horizontal setting has to set from the top-most class to the table generating class. At the moment there is no tool support, therefore, it is necessary to set the top-most class to horizontal and copy the xml node to all other classes that should be stored in the same table.

Decimal as primary key in Reverse Engineering supported in case of Multiple Field identity

Improvement: VOA-1471

Due to rounding problems on the server OpenAccess was not generating the right code if it had to map the primary key to a decimal field. Now, System.Decimal is allowed as a primary key field while using Multiple Field Identity. However, for single field identity, System.Decimal is not supported.

OpenAccess is sometimes really slow when a debugger is attached

Improvement: VOA-1575

Sometimes an operation that takes normal time during application execution needed 10-20 times more inside the debugger. The reason for this was that OpenAccess threw a lot of exceptions that are cached immediately. The amount of thrown exception has been reduced dramatically.

.NET 2.0 Signed Assemblies Enhanced

Documentation: VOA-1574

.NET 2.0 assemblies can be signed using any mechanism. However, delayed signing is not supported.

Check Setting Dialog Enhancement

Documentation: VOA-1582

Check Setting Dialog: Mapping Validation Errors - Field not found and Class not found now can be fixed automatically, i.e., when you click on Execute Fix icon, the reference entry for that particular field or class will be removed from the App.config file.

Transaction Chapter Enhanced

Documentation: VOA-1583

The transaction chapter has been enhanced to clearly descibe transactions and add more information about where they should be used.

Abstract class: Struct Problem

Fix: VOA-1580

If you have a class hierarchy with an abstract class in the middle that contains a struct, objects of the derived types cannot be stored. A null reference exception is thrown.

The Mapping Dialog hangs if you try to make a class with a generic interface persistent

Fix: VOA-1584

If a class that implements a generic Interface like IList<T> or event List<T> is made persistent, the mapping dialog will enter an endless loop.

多层水平映射

新特性: VOA-1592

水平映射是位于层的最高处，严格限制于一层里。这个增强特性增加了把多层结构映射到一个表中的能力。

水平设置可以设置为从最高类映射到表格继承类。这时，不支持任何工具，然而，它对于设置最高类水平化是必须的，同时，还复制 XML 代码到另外类，并且保存到相同的表格中。

多域特性里反向工程学中的十进制主键支持

改进: VOA-1471

由于服务器中的环行问题，如果其把一个主键映射到十进制域的话，OpenAccess 就不能正确继承代码。现在，System.Decimal 允许在使用 Multiple Field Identity 时做为主键.但是，对于单域特性，就不支持 System.Decimal.

当加载了调试器时，OpenAccess 有时会很慢

改进: VOA-1575

有时正常情况下的应用程序操作只需要常规的时候，而在调试器中却需要 10-20 倍的时间. 原因是OpenAccess 会抛出许多异常，并且立刻堆积在缓存中. 现在，大量的抛出异常显著地减少了。

.NET 2.0 符号编译加强

Documentation: VOA-1574

.NET 2.0 编译能在任何机制下进行有符号操作。但是，它不支持延时符号。

检查设置对话框增强

Documentation: VOA-1582

检查设置对话框：映射确认错误- 以前的不能正确找到域和类的情况现在能自动修正了，比如，当你点击执行图标时，特殊域或了类的相关条目就会从 App.config 文件中移除。

事务章节增强

Documentation: VOA-1583

事务处理章节已经得到了增强，能显著地描述事务，并且增加了更多的在哪儿使用他们的信息。

抽象类：结构问题

修正: VOA-1580

如果你有一个带抽象类的类层次，并且该类中包含了一个结构，派生类的对象不能被保存，会抛出一个空的引用异常。

映射对话框固定功能，如果你试图生成一个有固定界面的继承类时。

修正: VOA-1584

如果一个类实现了一个继承的界面，就像IList<T> 或事件 List<T> 那样固定, 映射对话框会进入一个无穷循环.
