I have this function:

int SOMECLASS::ADDTABLE(const DBTABLE* old)// both classes (SOMECLASS &
ADDTABLE) are __gc classes
{
old->GetName(); //<-- ERROR: 'GetName' cannot convert 'this' pointer
from 'const DBTABLE' to 'DBTABLE __gc &' Conversion loses qualifiers
//blah,blah....
}

If I remove the const modifier it compiles fine, however I don't want to
remove it. How can I get around this error?

Thank You
josh

You can use 'const_cast' but this will be the same as removing the const
definition of the ;old; parameter.

declare GetName() as const method of DBTABLE. (if you have access to
the source code, that is)
