不可能的事

最好把异常帖出来看一下

是不是你根本没有把出错的代码包含在TRY里面

我的语句如下：但不能捕捉数据异常 
  while(!DataModule4->ADOQuery2->Eof)
          {
                  //捕捉由数据库产生的异常
             try
               {
                 k=k+1;
                 j=int(k*100/i);
                 CGauge1->Progress=j;
                 DataModule4->Table4->Edit();
                 DataModule4->Table4->Insert();
                                 //zhi
                DataModule4->Table4->FieldByName("zhi")->Value=DataModule4->ADOQuery2->FieldByName("zhi")->Value;
                
                //riqi
                DataModule4->Table4->FieldByName("riqi")->Value=DataModule4->ADOQuery2->FieldByName("riqi")->Value;
                DataModule4->Table4->Post();
                DataModule4->ADOQuery2->Next();
            }
           //异常的捕捉

             catch(...)
              {
              ShowMessage("产生异常！");
               DataModule4->ADOQuery2->Next();
              }

               }
