/////////////////////////////////////////////////////////////////////
// Modify any class.

// 1) implement a member function of a class
int CWzdView::ViewFunc(int i,LPCSTR s,BOOL b)
{
	i;s;b;		//values are processed
	return 0;	//result is returned
}

// 2) define a variable type that defines this member function
typedef int (CWzdView::*PMFUNC)(int,LPCSTR,BOOL);

NOTE: PMFUNC above becomes the variable type name


// 3) when using this new variable type, you must also include a variable
// that points to the class that this function belongs to
void CWzdUtil::Perform(CWzdView *pClass, PMFUNC func)
{
		:	:	:
}

// 4) to use this new variable type 
void CWzdUtil::Perform(CWzdView *pClass, PMFUNC func)
{
	int i=(pClass->*func)(1,"test",TRUE);
