delphi dll 实例 与 dll窗体实例
本动态链接库方法有
Min,Max,SynAPP,ShowForm,showmyform
dll工程文件
Library Project1;

为了加快硬件的访问速度, 编译器通常要使用"数据对齐", 譬如:
//下面结构中: SizeOf(TRec) = 6; 因为 b 在这里也要占 2 字节.
TRec = record
a: Word;
b: Byte;
c: Word;
end
;
//下面结构中: SizeOf(TRec) = 16; 这里的 a 和 b 共占了 8 个字节.
TRec = record

较强，先获取最大的顶层框 ......
