Error with dynamic_cast

msr_codeproject

class Filter;

typedef void (Filter::*PFN)();

class Filter
{
public:
void ProcessPart();
void MyProcessPart();

struct Pair\_t
{
	Pair\_t(int d, PFN n) : iid(d), pfn(n) {}

	int  iid;
	PFN  pfn;

private:

	Pair\_t& operator=(const Pair\_t&);
};

};

void Filter::ProcessPart()
{
PFN pfn2;

    //Here I am getting error C2681
pfn2 = dynamic\_cast (&Filter::ProcessPart);

Pair\_t(9, pfn2);

}

int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}

I am not able to solve this. Any help? Thanks

You are trying to cast a function address to a pointer to a class, which is illegal.

Function pointer casting has a really crappy syntax in C. I posted on it way back, but so ugly is I have totally forgotten how it goes.

You've already had help from the clever people here, but it would have helped them if you'd put the error in the posting too. If you make it easy to help you, more people will try. Iain.

Ahem, it's in the original question, as a C++ comment.

OK, I'll partially let him off then! But pasting the whole error message is still wise. Do *you* remember E1234 off by heart? Iain.

I agree entirely.

No, but I can spell MSDN and even Google. ;)
