I'm having trouble reading values from a .ini file on windows 7 x64.
Specifically, changes that I make in a text editor are not appearing
when I try to read them in through my application. Other settings that
have been in the .ini file for ages will read in just fine; just not the
new entries. When I try to read the new entries, I'm just getting back
my default value, so it's not reading from the .ini file.

I have made the changes in both copies of my .ini file: the one in c:
\windows, and the one in my appdata\local\virtualstore\windows folder,
and while changes in either one of these appear in the other in the text
editor, they will not show up when I read them in from my app, even
though long-standing entries work fine. Is there a 3rd copy of the .ini
file around somewhere that I can't find? I did both a registry search
(which turned up nothing, as expected), and a HD search which turned up
only those two listed above.

I'm sure it's something to do with win7's virtualization, but can't
figure out how to get around it; can somebody tell me what I'm missing?
Is there some caching I need to work around?


My code I'm usiing is:

labelName = GetIniString("WebSIRA", "OspFullLabel", "", "WinTM.ini")


and GetIniString is:


Function GetIniString$(AppName$, KeyName$, Default$, IniFileName$)
'calls windows API call to get the desired string from the specified
..ini file
ReturnString$ = Space(255)
BuffSize& = Len(ReturnString$)
StringLen& = GetPrivateProfileString&(AppName$, KeyName$, Default$,
ReturnString$, BuffSize&, IniFileName$)
GetIniString$ = Left$(ReturnString$, StringLen&)

End Function



Thanks!

Don't be so sure of that.

Sounds as if you're either reading the wrong file or the file is in a folder
for which there is only read access (so therefore changes aren't being
written), which is a possibility under Vista and Win7 even for members of
the Administrators group.

Provide a full path to the INI file AND make sure it's a folder to which the
user has both read and write permissions. But do NOT hard-code the path.
Use SHGetSpecialFolderPath to obtain the path. If you need example code for
calling that function, search the newsgroups at www.google.com or another
search engine.
