POIs there a way to compile-time assert if a variable is a class, struct or a basic type in c++?

    1. COAs an aside, why do you care whether it is a class or a struct? Anything could be a class or a struct. Actually if you choose not to rely on the default "private:" for class and "public:" for struct, and instead you write them explicitly, you could change all your classes to structs or vice versa without changing the meaning or behaviour of the code at all.

    2. COThe reason for this check is that I have a template function that has most of the functionality the same for every type but there's a part that handles polymorphic classes differently than other types. I've solved the problem for checking if a class is polymorphic with a similar test as the one above ( in my case polymorphic classes must have a certain function that I look for in the test ). But that test doesn't compile if the variable given to the function is not a class type so I need to test before that at least if it's a class or not.

    3. COI actually haven't tried that test with a structure but it would make things easier for me to dismiss a structure in a previous test as it can't be polymorphic.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
