Writing value to config file

[meinhunna]

am trying to write value for a key in <appSettings><add key="LidbsdPath" value="" /></appSettings> section of config file from vb.net app, using statement below

System.Configuration.ConfigurationSettings.AppSettings.Set("LidbsdPath", g_strLidbsdPath)

I am getting an error message saying "Collection is read-only"? How can I fix this

Here is an article trying to deter people from doing this and giving detail reasons.

However, there are classes out there that will write back to the config file you really want to.

If you can get past the arogant insulting nature of the author, he does make a valid point. (and a mildly moronic one about the write access in the program files folder).

Saving you application's config info in it's folder means that you can only have 1 set of settings. Even if you have 2+ users on the same machine (common in business settings, more common in schools, and an absolute in terminal systems like Cytrix).

Saving info to a config file in the user's Application Data folder will make it part of their roaming profile. That means that any number of people could log on to that machine and have their own settings, and that they could goto any other machine on the network (provided they have a Roaming Profile) and have the same settings.

so, use the 2 environment functions he mentions:

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

For user settings

Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData)

For common application settings for all users
