vb 读写配置文件

下面这些代码可以实现对.INI文件的读写,用标准模块保存它..

Attribute VB_Name = "INIReadWrite"

Private Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, _

ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long

Private Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, _

ByVal lpKeyName As Any, ByVal lpString As Any, ByVal lpFileName As String) As Long

''lpApplicationName 要在其中写入新字串的小节名称。这个字串不区分大小写

''lpszSection String 指定要在其中写入新串的小节。如尚不存在，会创建这个小节。这个字串不区分大小写。

''lpszKeyName String 要设置的项名或条目名。这个字串不区分大小写。用vbNullString可删除这个小节的所有设置项。

''lpszString String 指定为这个项写入的字串值。用vbNullString表示删除这个项现有的字串。

''lpFileName 读取文件名

Dim INIFilePath As String

Sub SetINI(ByVal INIPath As String)

INIFilePath = INIPath

End Sub

Sub WriteKey(ByVal Section As String, ByVal Key As String, Optional ByVal KeyValue As String = "")

WritePrivateProfileString Section, Key, KeyValue, INIFilePath

End Sub

Function ReadKey(ByVal Section As String, ByVal Key As String, Optional ByVal Size As Long = 256) As String

Dim Str As String

Str = Space(Size)

If GetPrivateProfileString(Section, Key, 0, Str, Size, INIFilePath) <>0 Then ReadKey = Str

End Function

窗体的话你可以自己设计下,因为不知道你想要什么效果,或者你可以就上面的代码用MsgBox输出Key值来看看效果..
