How to convert classname as string to a class?

Question

I have classnames in a stringlist. For example it could be \'TPlanEvent\', \'TParcel\', \'TCountry\' etc.

Now I want to find out the sizes by looping the list.

If your classes derive from TPersistent you can use RegisterClass and FindClass or GetClass . Otherwise you could write some kind of registration mechanism yourself.
