谢谢workers(玉蝴蝶)，你的程序很清楚我把你的程序加了很多的容错处理，但是我还有一个问题，就是 ： 当dbgrid中无记录的时候，点击导入，程序错，所以我加了 if dbgrid1.datasource1.dataset.recordcount = 0 then .............. 还是不行，主要是程序一开始，就点击导入的时候（dbgrid1中无记录）就出错。 请问我因为怎样写程序？
对于你的问题 应该这样写 if not datasource1.dataset.isempty then{判断dbgrid的内容是否不为空} ...

当dbgrid中无记录的时候，点击导入，程序错，所以我加了
