Find out if a class is inherited from a certain other class

How can you find out if a class is inherited from a certain other class? Is
there another way than using .BaseType several times?

hi, I am kind of confused aobut interfaces and abstract classes. In short as I understand it, an interface is like a contract between the class and the interface, so that certain funtions must be implemented. So if you have a class which inherits base class that inherts an interface, then your classes will have a standard. I suppose you can also check for interface at run time say when dll is loaded and see if it implememts whats...

I have a Public Interface defined in a class module. I also have a form that implements that interface After building the solution, I added an Inherited Form (inherited from the above-mentioned form) to the project via the IDE However, when I drop down the "(base class events)" list, I can't find the methods defined in the interface. I know the interface has been inherited because if I enter an "Implements" statement in the derived...

I'm using a stl-priority queue and want - find out if a certain item is contained in the queue - to be able iterate over all items without having to pop() them, order does not matter. I couldnt find methods for these which suprises me as both should be easily solvable with access to the underlying vector. Did I just miss these methods? Can I somehow access the vector to get . begin() .end() and .find()?

Could you tell me how many class members the C++ language synthesizes for a class type? Which members in a class aren't derived from parent classes? I have read the book The C++ Programming Language, but there isn't a detail and complete description on all the class members, aren't they important to class composing? Could you explain the special class behavior in detail? Thank you very much.

The only browser I have encountered that supports <colgroup><col class="behold"></colgroup> to apply a CSS style to a whole column, is Microsoft Internet Explorer. I have been told it SHOULD NOT do so, since this is not part of the specification. How then to you apply styles to entire columns? Surely you don't have to write <td class="behold"on every row item.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
