VB读写INI文件
'******************************************************************************************
'* 需要注意的问题 *
'******************************************************************************************
'1.INI文件的路径必须完整,文件名前面的各级目录必须存在,否则写入不成功,该函数返回 FALSE 值.
'2.文件名的路径中必须为 \\ ,因为在VC++中, \\ 才表示一个 \ .
'3.也可将INI文件放在程序所在目录,此时 lpFileName 参数为: ".\\student.ini".
'4.使用前请先初始化变量ProfileName

Private Sub Command4_Click()
