编写 main.aardio 如下

import win.ui;
/*DSG{{*/
winform = win.form(text="excel1";right=801;bottom=500)
winform.add(
button1={cls="button";text="读取Excel文件";left=19;top=14;right=126;bottom=44;z=1};
button2={cls="button";text="导出Excel文件";left=168;top=17;right=291;bottom=45;z=3};
listview={cls="listview";left=2;top=62;right=801;bottom=498;edge=1;gridLines=1;hscroll=1;vscroll=1;z=2}
)
/*}}*/
