constant variable help please 1

[MysticFallout]

I am trying to make a constant variable so I will not have to constantly re-create the variable throughout my application. The variable I am trying to make utilizes the GetSetting function. I don't understand this type of "Coding" very well, but I am reading up on it as I write this, but so far no idea on how I would do this.

private const showPrev as string = GetSetting("Wallpaper", "options", "Allow Preview")

But I am getting an error. "Constant Expression Required". Could someone please advise me on how I could do this?

Thank you in advance!

Constants are defined at compile time. Therefore, any value that you give them must also be resolved at compile time. The GetSetting() call does not fall into that category, as what it returns can change while a program is running (Ex: user runs RegEdit while program is running & changes the value).

Probably what you can do is put it in a class, inside a "Property Get", with no matching "Property Let". That way it behaves as if it were read-only.
