VB讀寫ini文件

領測軟件測試網 自從注冊表誕生以來ini文件正在逐漸失去其市場占有率，然而基于ini文件的獨立性，致使其還沒有到達退出歷史舞臺的地步，很多應用程序的初始化和一些界面參數的設置仍然很愿意從ini文件中讀取，為了保證操作需用參數對ini文件的讀取的通明性，建議使用一個模塊來完成此工作。注：所有操作調用標準的Win API函數來完成。

Dim Ret As Long

Dim Start As Long

Public FileName As String

Const BufSize = 10240

Dim buf As String * BufSize

Private Declare Function GetPrivateProfileInt Lib "kernel32" Alias "GetPrivateProfileIntA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal nDefault As Long, ByVal lpFileName As String) As Long



Private Declare Function GetPrivateProfileSection Lib "kernel32" Alias "GetPrivateProfileSectionA" (ByVal lpAppName As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long



Private 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



Private Declare Function WritePrivateProfileSection Lib "kernel32" Alias "WritePrivateProfileSectionA" (ByVal lpAppName As String, ByVal lpString As String, 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



Public Sub SetValue(ByVal clsName As String, ByVal key As String, ByVal V As String)

    Ret = WritePrivateProfileString(clsName, key, V, FileName)

End Sub



Public Function GetValue(ByVal clsName As String, ByVal key As String) As String

    Ret = GetPrivateProfileString(clsName, key, "", buf, BufSize, FileName)

       Start = 1

       GetValue = RetStr()

End Function



Private Function RetStr() As String

     Dim i As Long

     i = InStr(Start, buf, Chr(0))

     If i > Start Then

       RetStr = Mid(buf, Start, i - Start)

     End If

     Start = i + 1

End Function



至此已經完成了對一個完整的獨立模塊的封裝，接下來就來看看怎么引用（其實看完上面程序就明了了）
