#define TV_HEIGHT 200
//
HWND CreateTreeView(HINSTANCE hInstance, HWND hwndParent)
{
DWORD       dwStyle;
HWND        hwndTreeView;
BOOL        bSuccess = TRUE;dwStyle =   WS_TABSTOP | WS_CHILD | WS_BORDER | WS_VISIBLE ;//
            
hwndTreeView = CreateWindowEx(   WS_EX_WINDOWEDGE,//WS_EX_CLIENTEDGE,// ex style
                                 WC_TREEVIEW, // class name defined in commctrl.h
                                 NULL,                      // window text
                                 dwStyle,                   // style
                                 320,                       // x position
                                 120,                       // y position
                                 TV_WIDTH,                  // width
                                 TV_HEIGHT,                 // height
                                 hwndParent,                // parent
                                 (HMENU)IDC_TREEVIEW,       // ID
                                 (HINSTANCE)GetWindowLong(hwndParent, GWL_HINSTANCE), // instance
                                 NULL);                     // no extra data
//
if(hwndTreeView)
{
InitTreeView(hwndTreeView);
return hwndTreeView;
}
else
{
return NULL;
}
}
MFC：
资源中拖一个tree，就有了。
