From: Eduardo on 18 Dec 2008 16:34 Hi, Reading about checking directories existence and creating directories, a question came to my mind. I recentry changed the place where some of my programs save the data to make them Vista compliant, so I retrieve the APPDATA path and create a new folder there (if it doesn't exists already) and save the files there. But doing so I am relying on that the directory APPDATA will already exist in the client machine. My question is, can I rely that it will exist in Win95 and NT4 systems?

What a mess. They have said that before Vista it was recommended to write to APPDATA folder (and it is true), but they must think that every user has the latest OS version on their machines. I usually don't write my programs to run just on the latest version of Windows. So now I need to check the OS version, and then see if I write to the APPDATA folder or to somewhere else (the place that I used before). A lot of complication for something that should be very simple.

If the OS doesn't have an APPDATA folder, (shooting from the hip) you can just stick your configuration information in Program Files (or wherever your app is). -- ..NET: It's About Trust! http://vfred.mvps.org
From: Kevin Provance on 18 Dec 2008 18:32 It shouldn't be a problem from Win98 on up if you use the API. Granted, Win98/ME's location is based in the Windows folder, but when using the API, it is created automatically (I have tested this). - Kev "Karl E.

BTW, I already fixed it in one of my programs. fortunately I thought about this problem before I did any release. |
