這是一個(gè)很有實(shí)際學(xué)習(xí)意義的VB操作文本文件的一個(gè)實(shí)例，學(xué)習(xí)VB的朋友一定要認(rèn)真的看一看。
    \'功能：刪除、替換文本中一行，或者插入內(nèi)容到文本中某一行
    \'作者: soho_andy (冰)
    \'參數(shù)：
    \'strSourceFile 原始文件完整名
    \'strTargetFile 生成新文件的完整名
    \'intRow 操作的行數(shù)
    Sub 操作文件中一行(strSourceFile As String, strTargetFile As String, intRow As Long)
