还是采用OLE技术吗？大数据量(5万行)下有保证吗？

请给我一份，谢谢！E-Mail: samchoy@163.com

我将例程放在那里，要代码者给我写EMAIL。

源代码我已经收到，再次表示感谢。

但你还是用到了OLE技术的，也就是说必须在安装了Excel的机器上才可以的哦，HTMLToEXCEL函数中vExcelApp = Variant::CreateObject("Excel.Application");就是证明。

思路很好，但还是不能满足我的要求，哎:(

说得有道理,我忘了这一点.但是不安装了Excel的PC，也用不了Excel。

不要ole的pas,加入bcb中就行了.
