在做一个ActiveFormX 时,想定义一个对外的属性 类型为记录类型:
TMyrecord = Record
field1 : integer;
field2 : Widestring;
field3
wordBool;
end;
但是设计时 ,此类型(在ACTIVEFORM 接口设计器中生成的结构),生成的接口
property testrecord ....
类型却却不是 Tmyrecord 而是 TGUID 如何正确是ActiveForm 能够输出 一个类型为
自定义类型的 属性呢?

谢谢各位大虾 --- 咄咄帮忙!!!!

如果可能希望能给小弟发各例子一阅 ,不胜感激!!snguobin@sohu.com
 
引入类型库

引入类型库,什么意思? TmyRecord 的定义就是在类型库 Tbl中定义的。
在在ACTIVEFORM 接口设计器中生成的结构 中也能够看到,
但是 :

你在方法的参数中设置这个参数的类型是你自定义的纪录类型了嘛?对了,就应该不会错
 
不能直接输出自己定义 的 结构类型!
是吗?
没人感兴趣么?
 
用memorystream
 
这个是TLB文件的例子,你看看:
