Delphi中有没有关于#VALUE, #NULL类似值的处理方法？

[Quote=引用 4 楼 p412578 的回复:]
在把数据保存为excel时会报这个错：OLE Error 800A03EC

一般是由下面几个造成的：

1、缺少这个：use ComObj, 没有引用单元文件；

2、没有创建OLE对象直接引用了，应该这样：MyExcel:=CreateOleObject(Excel.Application);

3、对单元格赋值或赋表达式不正确导致的，或超出excel可识别值的范围；

如：XlsSheet.Cells[i,j].Value := Cells[j,i]; 当cell[0,0]就会报这个错，因为excel单元格不是从[0,0]开始的；

[/Quote]

我这里是因为第三点，谢谢了

我是使用软件的，我的程序是用拼音码调用品名的,一输入字母"C"程序就关闭,用杀毒软件杀了一后,再启动程序,输入"C"程序没退出,就出现这个提示,关了以后,还是按字母"C"退出.

上面的注意修改掉SQL語句和SAVEAS的存儲路徑就可以你用了。編程愉快

ExcelApp.WorkSheets[1].Cells[i,1].Value 你要这样写，不能对excelapp直接付值
