This is just a part of Tips & Tricks you can use
I was trying to store some data in Isolated Storage through an ASP.NET Web Page.
I have used the below code,
Using isoStore = IsolatedStorageFile.GetUserStoreForApplication()
This particular line of code was giving me below error
Error : Unable to determine application identity of the caller
But luckily, before I go in deep and try to fight with this error, I got the solution Application scoped isolated storage is only available if your program is running as a ClickOnce application. If it is not, you'll get an IsolatedStorageException when you call GetUserStoreForApplication which says "Unable to determine the application identity of the caller.
So now, instead of using above code, change your code as per below to make your application work
Dim isoStore As IsolatedStorageFile
isoStore = IsolatedStorageFile.GetStore(IsolatedStorageScope.User Or _
IsolatedStorageScope.Assembly Or IsolatedStorageScope.Domain, Nothing, Nothing)
Thanks Frds!! Hav fun!!
