Help Exception C++

[JeeX 38]

Hey guys.

I wanted to create a exception but my core crashes...

 

here my code:
 

bool IsExceptions(DWORD dwVnum)
{
	switch (dwVnum)
	{
		case 30036:
			return true;
	}
	return false;
}

bool CItem::IsItemBox()
{
	LPITEM	item;

	return (GetType() == ITEM_MATERIAL && !IsExceptions(item->GetVnum()));
}

i Know the bool IsExceptions isnt correctly...

i wanted - that the return will load all items from ITEM_MATERIAL but i want an Exception - he should check if there is a vnum there and if yes he should ignore this vnum
So -> [return] Load all from ITEM_MATERIAL but not this item...
i tryed with an int function - but i wanted a new function like my bool IsExceptions! - because i need this in more lines and i wanted to create a global one.

Someone how could help?

Best regards!

if (!IsExceptions(item->GetVnum()))
{ 
	LPITEM	item;
	return (GetType() == ITEM_MATERIAL);
}

Ofc it crash when you call function GetVnum() through a null pointer 

bool CItem::IsExceptions(DWORD dwVnum)
{
	switch (dwVnum)
	{
		case 30036:
			return true;
        		break;
	}
	return false;
}

bool CItem::IsItemBox()
{
	//LPITEM	item; // why ?

	return (GetType() == ITEM_MATERIAL && !IsExceptions(GetVnum())); 
	// Just call GetVnum() or like that: this->GetVnum()
}
