VB读写INI文件

给你两个读取ini文件的过程吧

'读取配置文件

Public

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

'写入配置文件

Public

Declare

Function

WritePrivateProfileString

Lib

"kernel32"

Alias

"WritePrivateProfileStringA"

(ByVal

lpApplicationName

As

String,

ByVal

lpKeyName

As

Public

Function

ReadOption(ByVal

Caption

As

ByVal

Item

As

Resume

Next

Dim

sBuffer

Space(128)

GetPrivateProfileString

Caption,

Item,

vbNullString,

sBuffer,

128,

End

Function

'获得配置文件路径

Public

Function

GetOptPath()

As

String

GetOptPath

=

App.Path

&

"\config.ini"

End

使用api函数：给你个模块代码：

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 WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpString As String, ByVal lpFileName As String) As Long

Public Function GetPPs(ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpDefault As String) As String

Dim Ret As String, NC As Long, ln As Long

ln = &H7FFF

Ret = String(ln, 0)

If Right(App.Path, 1) = "\" Then

NC = GetPrivateProfileString(lpApplicationName, lpKeyName, lpDefault, Ret, ln, App.Path &"SoftConfig.ini")

Else

NC = GetPrivateProfileString(lpApplicationName, lpKeyName, lpDefault, Ret, ln, App.Path &"\SoftConfig.ini")

End If

Ret = Left(Ret, NC)

Dim t As String

t = Ret

t = Replace(t, "{Chr(9)}", Chr(9))

t = Replace(t, "{Chr(10)}", Chr(10))

t = Replace(t, "{Chr(13)}", Chr(13))

t = Replace(t, "{Chr(32)}", Chr(32))

t = Replace(t, Chr(0), "")

GetPPs = t

End Function

Public Function WritePPs(ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpKeyVal As String) As String

Dim t As String

t = lpKeyVal

t = Replace(t, Chr(9), "{Chr(9)}")

t = Replace(t, Chr(10), "{Chr(10)}")

t = Replace(t, Chr(13), "{Chr(13)}")

t = Replace(t, Chr(32), "{Chr(32)}")

If Right(App.Path, 1) = "\" Then

WritePrivateProfileString lpApplicationName, lpKeyName, t, App.Path &"SoftConfig.ini"

Else

WritePrivateProfileString lpApplicationName, lpKeyName, t, App.Path &"\SoftConfig.ini"

End If

End Function
