为什么一添加数据就出现"Stack Overflow"错误?(100分)

用Paradox的数据库应用程序,以前都很正常的;
最近修改了一下界面重新编译后却运行出问题了,
具体表现为:在本机运行添加数据就出现"Stack Overflow"错误,
在另外的一台机运行添加数据就出现"该程序执行了非法操作"；
各位有什么好的解决方法吗？谢谢！

Stack Overflow错误一般是死循环引起的，你说得不清楚，看不出问题的

说明白点

是呀，应该把相关的代码让大家看看才行呀

可能是表内有错误

可能是二楼的原因。

我以前也碰到这样的问题,是不是用了这样的代码:
function MyFunction: Integer;
begin
MyFunction := MyFunction + 1;//用Result好些,MyFunction :=MyFunction + 1形式有些时候后堆栈溢出
end;

贴代码看看

非常感谢各位，下面是物品进仓的部分代码：

to 楼主：
你这样写也不标出Bug在哪出现，怎么给你答案？
快修改你的注释吧。

在本机运行添加数据就出现"Stack Overflow"错误,
在另外的一台机运行添加数据就出现"该程序执行了非法操作"；

这代码已经经过你的处理了吧，不然我看那个refresh函数就是莫名其妙的，
什么可能编译得通过呢？添加记录会触发beforeinsert，保存前会触发beforepost，
你跟踪进去看看问题是出在什么地方~~~~（我的眼光不够明锐，没看出来）

死循环

接受答案了.
