經??吹接芯W友發(fā)帖子詢問如何將DBGrid中的內容導出到Excel或Word文檔中,于是筆者花了點時間寫了以下兩個函數(shù),分別實現(xiàn)將DBGrid中數(shù)據(jù)導出到Word和Excel文檔。需要注意的是DBGrid中的數(shù)據(jù)并不代表數(shù)據(jù)庫中所有的數(shù)據(jù),因為數(shù)據(jù)集在打開的時候有可能進行了篩選,取決于使用者如何打開這個數(shù)據(jù)集,總之就是DBGrid中顯示多少數(shù)據(jù),就導出多少。
一、將DBGrid中的內容導出到Word文檔

try
{
vWordApp = Variant::CreateObject("Word.Application");
