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.

1. You have to use FindClass to find the class reference by its name. If class is not found, then the exception will be raised.
2. Optionally, you have to call RegisterClass for your classes, if they are not referenced explicitly in the code.
