INI 文件读写
INI内容为未知[section1]
keyword1=valuel
keyword2=value2
……
[section2]
keyword1=value1
keyword2=value2
……
我想读取 SECTION1的值 和section1里的KEYWORD值
我已经有可以读取未知SECTION1的代码
可是如何读取未知的section1里的KEYWORD值 --------------------编程问答--------------------
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
Function GetProString(段 As String, 标题 As String, 默认值 As String, 文件名 As String) As String
Const ProStringLen = 8096
Dim Res As Long, S As String, i As Long
S = Space(ProStringLen)
Res = GetPrivateProfileString(段, 标题, 默认值, S, ProStringLen, 文件名)
S = Trim(Left(S, Res))
If S <> "" Then
i = Len(S)
Do While Mid(S, i, 1) = vbNullChar
i = i - 1
Loop
S = Left(S, i)
End If
GetProString = Trim(S)
End Function
Private Sub Form_Load()
Dim Apps() As String, i As Integer
Apps = Split(GetProString(vbNullString, vbNullString, "", "c:\xx.ini"), vbNullChar)
Debug.Print "项目总数=" & UBound(Apps) - LBound(Apps) + 1
For i = LBound(Apps) To UBound(Apps)
Debug.Print "第" & i; "项 = " & Apps(i)
Next i
End
End Sub
以上是读取INI文件中未知[SECTION1]的代码 --------------------编程问答--------------------
