Ok now the problem is this.
I have compiled some old code with Visual Studio 2008 (the
code was originally writen in Visual Studio 6) and i have this
error:
Error 1 error C2681: 'void *' : invalid expression type
for dynamic_cast c:\Works\BaCCTester\Dev\Addins\Utils
\CommonDataManipulators\Sources\CommonDataFree.cpp 121
CommonDataManipulators
and the problematic line of code is this:
...
FunctionResponse* pFunctionResponse =
ACE_dynamic_cast(FunctionResponse*, data);
...
So it is logicaly that dynamic_cast does not work for
void-pointers since when I converted the pointer to void I
have given up all type information. But what makes me think
twice about the corectness of the previous sentence is that
this code compiles perfectly under Visual Studio 6. I would
like to know more about this issue so any help, references,
links and so are highly appriciated.
The real question is what ACE_dynamic_cast is. I suspect that
it's a macro, and probably expands differently depending on the
compiler, but I really don't know.
