Hi Henk,

WMSize is a private member function of TCustomDBGrid and thus not
accessible in a derived class.

Modify your class definition like this:

class TMyDBGrid : public TCustomDBGrid
{
private:
void __fastcall WMSize (TWMSize &Message);

...

BEGIN_MESSAGE_MAP
MESSAGE_HANDLER(WM_SIZE, TWMSize, WMSize)
END_MESSAGE_MAP(TCustomDBGrid)
}

and add the WMSize member function like this:

void __fastcall TMyDBGrid::WMSize (TWMSize &Message)
{
// Call the inherited message handler.
TCustomDBGrid::Dispatch(&Message);

// Do your own processing here.
}

Regards,

Martin Nijhoff
