Customized BEGIN_TEMPLATE_MESSAGE_MAP with 2 template arguments for VS2005

funwithdolphin

Hi, I am getting below compiler error on Visual Studio 2005: isodirbrowserlistctrl.cpp(46) : error C2906: 'const AFX_MSGMAP *CListDataCtrl<B,T>::GetThisMessageMap(void)' : explicit specialization requires 'template <>' with [B=CListCtrl,T=CBrowserListCtrlData Here is the code with .h and .cpp files. This code used to compile and run fine on Visual Studio 6.0. I guess I need to use BEGIN_TEMPLATE_MESSAGE_MAP. But BEGIN_TEMPLATE_MESSAGE_MAP can not handle more than one template arguments. In my case, there are 2 template arguments.

// ListDataCtrl.h : header file
//
class CListDataBase
{
public:
CListDataBase() : m_iItem(-1), m_pCtl(0) {};
void SetControl(CListCtrl* pCtl) { m_pCtl = pCtl; }
CListCtrl* GetControl() { return m_pCtl; }
void SetItemNumber(int iItem) { m_iItem = iItem; }
int GetItemNumber() { return m_iItem; }

protected:
int m_iItem;
CListCtrl *m_pCtl;
};

}

{
	T\* pData = (T\*) GetItemData(iItem);
	delete pData; pData = 0;
	SetItemData(iItem, 0);
}

void DeleteListData(int iItem)
{
	DeleteListDataPrim(iItem); 
}

BOOL DeleteListNode(int iItem)
{
	DeleteListData(iItem);
	return DeleteItem(iItem);
}
void SetListData(int iItem, T\* pData)
{
	pData->SetItemNumber(iItem);
	pData->SetControl(this);
	DeleteListData(iItem);
	SetItemData(iItem, (DWORD) pData);
}

void DeleteAllListData()
{
	int cMax = GetItemCount();
	for (int i=0; i<cMax; i++)
	{
		delete (T\*) GetItemData(i);
		SetItemData(i, 0);
	}
}

{
	DeleteAllListData();
	DeleteAllItems();
}

T\* InsertItemData(LPCTSTR ptszText, int iItem, T\* pData = 0)
{
	if (!pData)
	{
		pData = new T;
	}
	int iNewItem = InsertItem(iItem, ptszText);
	SetListData(iNewItem, pData);
	return pData;
}

See if this[^] can help.

I looked at it. But it has Customized BEGIN_TEMPLATE_MESSAGE_MAP only for VC7. It doesn't have mention of Customized BEGIN_TEMPLATE_MESSAGE_MAP for VS2005/VC8.

Well, other than "extracting" the macros yourself and adding the template parameters where needed i have no better idea yet if those don't work for VS2005/8 as you said...
