[建议] VB读取INI文件很有用, 可以直接读取指定文件行

Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" _
(ByVal lpApplicationName As String, _
ByVal lpKeyName As Any, ByVal lpDefault As String, _
ByVal lpReturnedString As String, ByVal nSize As Long, _
ByVal lpFileName As String) As Long

Public Function ReadIni(ByVal file As String, ByVal section As String, _
ByVal key As String, ByVal default As String) As String

Dim x As Long
Dim sSection As String, sEntry As String, sDefault As String
Dim sRetBuf As String, iLenBuf As Integer, sFileName As String 'Six arguments
sSection$ = section
sEntry$ = key
sDefault$ = default
sRetBuf$ = String$(256, 0) '256 null character
iLenBuf% = Len(sRetBuf$)
sFileName$ = file

'function will return a value of 12 in this case
x = GetPrivateProfileString(sSection$, sEntry$, sDefault$, sRetBuf$, iLenBuf%, sFileName$)

'sValue$ will contain the string 'PACKARD BELL'
sValue$ = Left$(sRetBuf$, x)

'return value
ReadIni = sValue$
End Function Sub Test_ReadIni()
MsgBox ReadIni("d:\test.ini", "TEST", "2", "null")
End Sub 文件d:\test.ini的内容: [test]
1=hello
2=world
3=!

不过用程序读写INI文件都很麻烦，而且Windows几乎经把ini这种保存信息形式抛弃了．
