MFC点击按钮显示OPenGL图像未遂。。。大家帮我看看啊~

[cengyunmuxue]

本来应该是点击按钮显示图像的，但是点击以后什么也没有，大神们帮我看看问题出在哪里，小女子不胜感激啊。。。
我为OPenGL单独添加了一个类CGLWindow，CGLPointDlg来控制。代码如下。。。小白一枚，大家慎拍砖啊。。。

BOOL CGLPointDlg::OnInitDialog()
{
	CDialog::OnInitDialog();

	// Add "About..." menu item to system menu.

	// IDM_ABOUTBOX must be in the system command range.
	ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
	ASSERT(IDM_ABOUTBOX < 0xF000);

	CMenu* pSysMenu = GetSystemMenu(FALSE);
	if (pSysMenu != NULL)
	{
		CString strAboutMenu;
		strAboutMenu.LoadString(IDS_ABOUTBOX);
		if (!strAboutMenu.IsEmpty())
		{
			pSysMenu->AppendMenu(MF_SEPARATOR);
			pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
		}
	}

	// Set the icon for this dialog.  The framework does this automatically
	//  when the application's main window is not a dialog
	SetIcon(m_hIcon, TRUE);			// Set big icon
	SetIcon(m_hIcon, FALSE);		// Set small icon
	
	
	HDC hDC = ::GetDC(this->m_hWnd);

	PIXELFORMATDESCRIPTOR pfd;
	// Choose a pixel format that best matches that described in pfd
	int nPixelFormat = ChoosePixelFormat(hDC, &pfd);
	DescribePixelFormat(hDC, nPixelFormat, pfd.nSize, &pfd);

	// Set the pixel format for the device context
	SetPixelFormat(hDC, nPixelFormat, &pfd);
	::ReleaseDC(this->m_hWnd, hDC);
	WNDCLASS wndClass;

	wndClass.style = CS_OWNDC;
	wndClass.lpfnWndProc = AfxWndProc;
	wndClass.cbClsExtra = 0;
	wndClass.cbWndExtra = 0;
	wndClass.hInstance = AfxGetInstanceHandle();
	wndClass.hIcon = NULL;
	wndClass.hCursor = NULL;
	wndClass.hbrBackground = NULL;
	wndClass.lpszMenuName = NULL;
	wndClass.lpszClassName = "OpenGLClass";

	// Register the window class
	AfxRegisterClass(&wndClass);

	CRect glRect;
	CRect dlgRect;
	CRect clRect;
	GetWindowRect(&dlgRect);
	GetClientRect(&clRect);
	GetDlgItem(IDC_TEST_FRAME)->GetWindowRect(&glRect);
	newRect.top = glRect.top - dlgRect.top - (dlgRect.Height() - clRect.Height()) +20;
	newRect.bottom = glRect.bottom - dlgRect.top - (dlgRect.Height() - clRect.Height()) -3;
	newRect.left = glRect.left - dlgRect.left - (dlgRect.Width() - clRect.Width()) +9;
	newRect.right = glRect.right - dlgRect.left  - (dlgRect.Width() - clRect.Width()) -1 ;
	return TRUE;  // return TRUE  unless you set the focus to a control
}


void CGLPointDlg::OnDisplayBT() 
{
	// TODO: Add your control notification handler code here
//	HDC hDC = ::GetDC(this->m_hWnd);
	int i = 0,j = 0;

	for(i=0;i<204;i++){
		for(j=0;j<204;j++){
			DMatrix[204*i+j] = abs(rand())/1000;}}

	m_glWnd.DestroyWindow();
	MessageBox("here we'll launch.",NULL,MB_OK);
	m_glWnd.Create("OpenGLClass",NULL,WS_CHILD | WS_VISIBLE | WS_CLIPCHILDREN | WS_CLIPSIBLINGS,
			newRect,this,110,NULL);
	m_glWnd.Invalidate(FALSE);
//	::ReleaseDC(this->m_hWnd, hDC);
}
float CGLPointDlg::MatMax(float* Mat)               //求最大值
//float MatMax(float* Mat) 
{
	int i=0; 
	float Max=Mat[0]; 
	for(i=0;i<204*204;i++) if(Max<Mat[i]) Max = Mat[i]; 
	return Max;
}

未遂这字眼看起来有点。。。容易让人联想到弓虽x未遂。。。
开个玩笑，楼主你下了nehe的opengl教程来看没？
跟着他的例子一课一课学，很快就能上手了

我看了OPENGL super bible 我这现在是不知道问题出在哪儿了 编译也没有错误 单步也没看出问题来 好纠结>_< 你说的那个教程我找找先看一下 谢谢啦
