Import ADOX type library and execute

//strConn is connection string.

Adox_tlb::TCOM_Catalog cat = CoCatalog::Create();
 cat->Create(strConn.c_bstr());

or

  CatalogPtr cat = CoCatalog::Create();
  cat->Create(strConn);


You may also need to add (for C++ Builder 6)

#include <comobj.hpp>

namespace System
{
 void __fastcall CheckSafecallResult(HRESULT hr)
 {
  OleCheck(hr);
 }
}

All strings should be declared as WideString, not as AnsiString.
