Hi Experts,
I've few application which share same settings. They all located at different folders. Some of the application are running as com dll so App.exe.config refers to the diff app name at run time.

Is there a way to use only 1 config file and shared by all the applications and com dlls? This will also simplify the process of maintaining too many config files with same settings.

Regards

For more flexibility with settings I use xml serialization and a custom settings class.  You can then serialize the class to disk in a controlled location.

I normally get the application data folder and append the appropriate path which can be done similar to the SettingsLocation function below.   You can change AllUsersApplicationData to CurrentUserApplicationData for user specific settings.

Word to the wise use the ApplicationData location if you want your application to act nice with Vista.
Public Class MySettings

 
 

Private _Value1 as string
 

Property Value1 as string

get

 return _value1

end get

set (byval value as string)

 _value1 = value

end set

end property

 

 

Public Sub SerializeToXML (byval path as string)

'there is a nice snippet under XML for this

....

 

Public Shared Sub ReadXML (byval Path as string) as MySettings

'snippet

.....

 

Public Shared Function SettingsLocation () as string

        Dim fileLocation As String = My.Computer.FileSystem.SpecialDirectories.AllUsersApplicationData

        fileLocation = IO.Path.GetDirectoryName(fileLocation)

        fileLocation = IO.Path.GetDirectoryName(fileLocation)

        fileLocation = IO.Path.GetDirectoryName(fileLocation)
 

fileLocation = io.path.combine(filelocation,"MyAppDirectory\MySettingsFileName.xml"
 

end sub
 
 
 

end class

Hi Corey,
Thanks for the response.

To be more precise, I only need to read the settings.

It would be more helpful if could give me some working sample code.

Even if you only need to read the settings it is nice to have a default xml created this example creates the xml if it doesn't exist. All you would have to do is modify the MySettings class to have a property for each setting you want.  The properties can also be classes as long as all the types are serializable.  (windows controls are not serializable)  anything you don't need to be serialized you can add an attribute of <System.Xml.Serialization.XmlIgnore()>
