what's wrong

[arjen]

Hi,

As a try-out I've made a simple Form application that reads times from a xml
file and appends the time of closing to that file. This works fine. The xml
file updates de file-time after using the program. The program and the xml
file have been installed on my computer (Program Files, folder). Still the
application works, but, the file time of the xml file is no longer updated.
I'm using VS 2005 and Windows 7 with Windows Installer. Should this work as
expected or is there something wrong (VS 2005/Windows Installer/Windows
7/me). I've tried to programmatically update the file time, but this does
not work at all. Is there anybody who can give me a hint to come out?

You have broken MSFT's rules!
You can't write to Program Files in Win7 (or Vista I think), you need to
find a more appropriate place to keep the file - look at
Environment.GetFolderPath in the help file.

You can not write to files in the Programs File folder under windows
vista or windows 7. You should be installing your file in the one of
the application data folders -
Environment.SpecialFolder.ApplicationData,
Environment.SpecialFolder.LocalApplicationData, or
Environment.SpecialFolder.CommonApplicationData - depending on how the
data is to be used by your application/users.

This is going to work. Thanks both of you!
