我用VC++制作一个对话框，想在一个对话框上显示一个旋转的立方体贴图，但是为什么只有立方体，而没有贴图呢？我的贴图是这样的：
下面是我的这个对话框的类的.cpp代码：
// locks.cpp : implementation file
//
#include "stdafx.h"
#include "user.h"
#include "locks.h"
#include "OpenGL1.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

//}}AFX_DATA_INIT
}
void Clocks::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(Clocks)

}

{
// TODO: Add your message handler code here and/or call default
copengl.Render();
CDialog::OnTimer(nIDEvent);
}
BOOL Clocks::OnInitDialog()
{
CDialog::OnInitDialog();
/************************************************************************/
/* 传递给SetupPixelFormat的参数是要绘图的对象的DC，可以是窗口中的某一个控件

/************************************************************************/
copengl.SetupPixelFormat(::GetDC(m_hWnd));
//得到绘图区域对应的长方形
CRect rect;
GetClientRect(&rect);
//设置绘图区域的宽和高
copengl.Init(rect.right,rect.bottom);
SetTimer(1,10,0);
return TRUE; // return TRUE unless you set the focus to a control
// 异常: OCX 属性页应返回 FALSE

下面是我定义的OpenGL类的cpp代码：
