Make ur destructor virtual and just use delete operator on base class pointer. U can also call destructor manually using downcasting by converting base class pointer to derived class pointer.

Hi, I want to create dynamic Microsoft Access Jet 4.0 database ( *.mdb) files and database schema ( tables (Data Definition Language ) ) using ADO connectivity. For that I have come up with the solution to use ADOX technology which provides database and schema creation facility, for Microsoft Access Database. So I want to know the latest version msadox.dll file thru which ADOX can be used to access database. And also write feasibility of using ADOX technology instead of ADO technology. Please be hurry........... Its urgent.... Thanks and Regards, Karnav Thanks and Regards Karnav Zaveri, Prodcut Development Engineer, Amtel Security Systems.

Hi all, Does aNy body know how we can pass strucutres ( types in VB ) as parameters of function defined in COM DLL interface ? For e.g. I have one interface called IDatabase and i want to add method like "HRESULT SetData([in]USER userData)". In this case the DLL is compiled successfully, but when it is used in the Visual Basic, it gives error "user defined object can not be passed by value". The DLL should be used in both VB and VC++ client applicaitons. Karnav Zaveri
