求救。。。。ini文件的操作

加一个项目记录一下一共有多少个字段。
关于INI操作如下：
'两个函数 , 先在一个模快中定义API函数
Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationname As String, ByVal LpKeyName As Any, ByVal lsString As Any, ByVal lplFilename As String) As Long
'如果是读INT值可以用字符串转化，所以没有另外定义函数
'Declare Function GetPrivateProfileInt Lib "kernel32" Alias "GetPriviteProfileIntA" (ByVal lpApplicationname As String, ByVal LpKeyName As String, ByVal nDefault As Long, ByVal lpFileName As String) As Long
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'定义读与写INI文件的函数
'＊＊＊＊读INI文件＊＊＊＊
'文件名 lpFileName 如果不存在会自己创建,如果只有文件名，默认在Windows\system目录下
'[lpAppName]
'lpKeyName=取回的设置值
'lpDefault 当键值不存在时的默认值
Public Function ReadINI(lpFileName As String, lpAppName As String, LpKeyName As String) As String
Dim Temp As String * 20
Dim lpDefault As String
lpDefault = ""
If GetPrivateProfileString(lpAppName, LpKeyName, lpDefault, Temp, Len(Temp), lpFileName) <= 0 Then
    ReadINI = ""
Else
    ReadINI = MyTrim(Temp) 'MyTrim函数见下
End If
End Function
'＊＊＊＊写INI文件＊＊＊＊
'[lpAppName]
'lpKeyName=lpString
Public Function WriteINI(lpFileName As String, lpAppName As String, LpKeyName As String, lpString As String) As Boolean
    If WritePrivateProfileString(lpAppName, LpKeyName, lpString, lpFileName) = 0 Then
        WriteINI = False
    Else
        WriteINI = True
    End If
End Function'包含三个函数，分别取Rtrim,Ltrim,Trim
'可以去字符串中如ASC码为0,10,13,32的字符
Public Function MyRtrim(Tmpstr As String)
Dim i, s As Integer
i = Len(Tmpstr)
If i = 0 Then
    MyRtrim = ""
    Exit Function
End If
s = Asc(Right(Tmpstr, 1))
While (s = 0 Or s = 13 Or s = 10 Or s = 32) And i > 0
    i = i - 1
    Tmpstr = Left(Tmpstr, i)
    If Len(Tmpstr) = 0 Then
        MyRtrim = ""
        Exit Function
    End If
    s = Asc(Right(Tmpstr, 1))
Wend
MyRtrim = Tmpstr
End FunctionPublic Function MyLtrim(Tmpstr As String)
Dim i, s As Integer
i = Len(Tmpstr)
If i = 0 Then
    MyLtrim = ""
    Exit Function
End If
s = Asc(Left(Tmpstr, 1))
While (s = 0 Or s = 13 Or s = 10 Or s = 32) And i > 0
    i = i - 1
    Tmpstr = Right(Tmpstr, i)
    If Len(Tmpstr) = 0 Then
        MyLtrim = Tmpstr
    Exit Function
    End If
    s = Asc(Left(Tmpstr, 1))
Wend
MyLtrim = Tmpstr
End FunctionPublic Function MyTrim(Tmpstr As String)
Tmpstr = MyLtrim(Tmpstr)
Tmpstr = MyRtrim(Tmpstr)
MyTrim = Tmpstr
End Function

    建立与读取.ini文件

　　虽然进入win95之後，一般读写ini文件被读写Registry所取代，但我们还是可以透过
win31的传统方式读写ini文件，以存程式目前的相关设定，而於下一次程式执行时再
读回来。目前建议使用GetSetting SaveSetting的方式存於Registry中，不用目前
的方式。储存程式的设定
