将数据窗口保存为Excel文件的方法
方法一：简单实用
string docname, named
integer value
value = GetFileSaveName("选择文件", &
docname, named, "XLS", &
"Excel文件(*.XLS),*.XLS")
IF value = 1 THEN
if dw_1.SaveAsAscii(docname)=1 then
messagebox('系统信息',docname+"保存成功！")
end if
end if
方法二：
/**********************************************
* 函数名称: changexecl(datawindow,tile) *
* 函数用法：datawindow为要转化的数据窗口； *
* tile为数据窗口的标题。 *
* 举例：changexecl(dw_1,"这是我们的世界") *
