高手看看CListCtrlEX这段代码错在哪里？谢谢！！

[yeyuanzhi2000]

在CConferenceDialog对话框建立了派生于CListCtrlEX类的m_olist控件，
然后在CMainFrame.h中声明
CConferenceDialog dlgBar;
在CMainFrame.cpp中的代码是：

void CMainFrame::OnAddMember(WPARAM wParam, LPARAM lParam)
{
	CString* pStr = (CString*)wParam;
	this->dlgBar.m_olist.SetItemText((short)lParam, pStr->GetBuffer(0), NULL);
	pStr->ReleaseBuffer();
}

CMainFrame::OnRemoveMember(WPARAM wParam, LPARAM lParam)
{
	CString* pStr = (CString*)wParam;
	if(!pStr->CompareNoCase("DUMP"))
		this->dlgBar.m_olist.DeleteAllItems();
	else
		this->dlgBar.m_olist.Remove(pStr->GetBuffer(0));
	pStr->ReleaseBuffer();
}

编译出错：
C:\MainFrm.cpp(1273) : warning C4101: 'sz' : unreferenced local variable
C:\MainFrm.cpp(2663) : error C2664: 'SetItemText' : cannot convert parameter 2 from 'char *' to 'int'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
C:\MainFrm.cpp(2673) : error C2039: 'Remove' : is not a member of 'CListCtrlEx'
c:\listctrlex.h(13) : see declaration of 'CListCtrlEx'
不知是什么问题，请高手出招，谢谢！！

另，我发现了一个问题，我把this->dlgBar.m_olist.SetItemText((short)lParam, pStr->GetBuffer(0), NULL)这段代码放到
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)下面，当我输到this->时，就会出现智能提示，但在void CMainFrame::OnAddMember(WPARAM wParam, LPARAM lParam)下面就不会出现，不知是什么原因？
