Cpp. NET: "a-> Methodname" vs "a.MethodName"

Question

I would like to know the difference between the two (sorry, I do not know the name of this topic).

I came from C # where I used to write System.data as well as classA.MethodA. I already found out that in Cpp with namespaces I need to use ::, with classmembers →. But what about the simple "."? I created a connection System :: data: odbc :: odbcConnection ^. Later I was able to use connection.Open. Why not connection-> open?

I'm sorry, I'm sure it’s easy to find something on the net, but I don’t know the English term for them. Thanks guys,

Answer 1

If you have a pointer to an object, you use:

MyClass *a = new MyClass();
a->MethodName();

, , :

MyClass a;
a.MethodName();

, , , :

System::Data::Odbc::OdbcConnection connect;
//You should be able to do this:
connect.Open();

, :

System::Data::Odbc::OdbcConnection^ connect1 = gcnew System::Data::Odbc::OdbcConnection();
connect1.Open(); // should be an error
connect1->Open(); //correct

I made a quick Google for you and THIS looks pretty fast and decent.
