怎么用vb读取INI里的内容并判断
Dim inistring As String
inistring = Space$(254)
GetPrivateProfileString "设置", "1010", "", inistring, 255, "c:\1010ini.ini"
If CStr(inistring) = "关闭" Then
Image6.Visible = False
Image5.Visible = True
Else
Image5.Visible = False
Image6.Visible = True
End If
有错吗？怎么不行？ --------------------编程问答-------------------- --------------------编程问答--------------------

我是先写成一个函数，省略很多麻烦
用的时候 inistring= GetINI("设置", "1010", "", "c:\1010ini.ini")
再不行你别用1010作为关键字，试试字母开头的 --------------------编程问答--------------------
