怎么用vb读取INI里的各值

[xiangyunff]

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

[cangwu_lee]

Private Function readStr(ByVal sapp As String, ByVal skey As String, Optional ByVal def As String = "") As String
Dim t As String
Dim r As Long
t = String(256, Chr(0))
r = GetPrivateProfileString(sapp, skey, def, t, 256, iniFileName)
If r > 0 Then
readStr = LeftB(t, r)
ElseIf InStr(1, t, Chr(0), 0) > 0 Then
readStr = Left(t, InStr(1, t, Chr(0), 0) - 1)
End If
End Function

僅僅提供參考！

Public Function Get_INI_String(ByVal Section As String, ByVal Key As String, ByVal Default As String, ByVal INI_FileName As String) As String
Dim X As Integer
Const BufferSize = 256
Dim tmp As String * BufferSize

Section = Section + Chr$(0)
Key = Key + Chr$(0)
INI_FileName = INI_FileName + Chr$(0)

X = GetPrivateProfileString(Section, Key, Default, tmp, BufferSize, INI_FileName)
Get_INI_String = Left$(tmp, X)
End Function
主程序調用時候
dim temp1,temp2 as string
temp1 = Get_INI_String("setting1", "keyword1", 1, filepath)的路徑
temp2 = Get_INI_String("setting2", "keyword1", 1, filepath)
filepath是ini文件所在

[jsnjtian]

filepath是ini文件所在路徑

[jsnjtian]

其中 GetPrivateProfileString 是一個api 函數

看我博客模块代码.

[tk600158]

反正达到效果就行了
我都是用

open app.path & "\a.ini" input as #1
do while not eof(1)
line input #1,a
msgbox a
loop
close #1

这样代码简单 呵呵 就是程序要慢点

'用法: 首先 定义iniFileName="文件名" 不需要 加ini后缀
'这就是说，你可以赋值给iniFileName就可以写入记录，而且你可以随时写入不同的ini文件(不管这个文件是否已存在），通过修改这个公用变量。

'然后   DelInikey（ByVal SectionName As String, ByVal KeyWord As String） 清除键
          'DelIniSec(ByVal SectionName As String)) 清除部
          'SetIniN(ByVal SectionName As String, ByVal KeyWord As String, ByVal ValInt As Long) 写入数
          'GetIniN(ByVal SectionName As String, ByVal KeyWord As String, ByVal DefValue As Long)读取数
          'SetIniS (ByVal SectionName As String, ByVal KeyWord As String, ByVal ValStr As String) 写入字符
          'GetIniS(ByVal SectionName As String, ByVal KeyWord As String, ByVal ValStr As String) 读取字符

'调用例子如下:
'
'Sub RiniN()
'Dim Initemp As String
'    Initemp = iniFileName '暂存原来的Ini文件名
'    iniFileName = App.EXEName '写入到另外一个Ini文件，App.EXEName是你的程序的名程
'    If GetIniN("lstBackup", "backupnumber", 0) < lstBackUp.ListCount Then
'        '这里的第三个参数“0”表示在没有找到指定的键值时返回的缺省值为“0”
'        SetIniN "lstBackup", "backupnumber", lstBackUp.ListCount
'        '......
'    End If
'    iniFileName = Initemp '继续使用原来的Ini文件

不错的代码收藏了。。。

[fzx4936]

INI中未知元素一律用VBNONESTRING来代替！
例如
lRet = GetPrivateProfileString(vbNullString, vbNullString, vbNullString, sBuf, 1024, App.Path & "\myini.ini")
可以取得所有的Section值
lRet = GetPrivateProfileString("XXXX", vbNullString, vbNullString, sBuf, 1024, App.Path & "\myini.ini")
可以取得XXXX所有的key值

[fzx4936]

不好意思 用红字还写错了
应该是VBNULLSTRING
