动态创建一个TreeCtrl，怎么改变风格没有效果！


m_ServerItemView.Create(WS_VISIBLE | WS_TABSTOP | WS_CHILD | WS_BORDER| TVS_HASBUTTONS | TVS_LINESATROOT | TVS_HASLINES| TVS_DISABLEDRAGDROP,CRect(0,0,0,0),this,IDC_SERVER_ITEM_VIEW);
m_ServerItemView.InitServerItemView(this);
g_GlobalUnits.m_ServerListManager.InitServerListManager(&m_ServerItemView);InitServerItemView(ITreeCtrlSink * pITreeCtrlSink)
{
LoadResource();
CImageHandle handle(&m_skinShow);
//设置控件
SetItemHeight(m_skinShow.GetHeight());
SetTextColor(RGB(0,0,0));
SetBkColor(RGB(255,255,255));
SetFont(&m_FontChild);
//ModifyStyle(0,TVS_HASBUTTONS|TVS_HASLINES|TVS_SHOWSELALWAYS|TVS_TRACKSELECT);
SendMessage(WN_SET_LINE_COLOR,0,(LPARAM)RGB(72,79,63)); //设置变量
ASSERT(pITreeCtrlSink!=NULL);
m_pITreeCtrlSink=pITreeCtrlSink;
//加载图片
if (m_ImageList.GetSafeHandle()==NULL)
{
CBitmap ServerImage;
ServerImage.LoadBitmap(IDB_SERVER_LIST_IMAGE);
m_ImageList.Create(18,18,ILC_COLOR16|ILC_MASK,0,0);
m_ImageList.Add(&ServerImage,RGB(255,0,255));
SetImageList(&m_ImageList,LVSIL_NORMAL);
}
}
