Virtual function 'BasicMidReader::~BasicMidReader()' conflicts with base class 'base 'TMemoryStream' |
Can anybody explain why can I not get rid of the above message
in the following class definition? [I am using Borland C++ Builder 5.0]
Thank you in advance.
class BasicMidReader : public TMemoryStream
{
//some private date
public:
BasicMidReader(char* FN)
{// some code}
~BasicMidReader() {// some code}
};
.

Did you mean <hint> Post real code whenever possible </hint>:
{ /* some code */ }
~BasicMidReader() {// some code}
};
I suspect this is A) a compiler bug, or B) something relating to
C++Builders non-standard language extension (TMemoryStream is a vcl
class) or C) (A) and (B).
So you should probably ask in a borland newsgroup, info here:
http://info.borland.com/newsgroups/
Just a random guess try puting __fastcall in the declaration of
BasicMidReader( char *FN ) i.e __fastcall BasicMidReader( char *FN ),
the dtor possibly needs it too.
HTH.

I can only guess. Maybe 'TMemoryStream's destructor has narrower
exception specification? Something like 'TMemoryStream::~TMemoryStream()
throw ()'? I don't know whether Borland's compiler detects this type of
error.
