Re: how to make dialog's background color

Hi,all
I am new to visual c++. I create empty dialog like this

class CMyWindow : public CFrameWnd
{
public:
CMyWindow ();
};

class CMyWinApp : public CWinApp
{
public:
virtual BOOL InitInstance();
};

CMyWinApp MyApplication;

BOOL CMyWinApp::InitInstance()
{
m_pMainWnd = new CMyWindow ;
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();
return TRUE;
}

CMyWindow ::CMyWindow ()
{
Create(NULL, "test",WS_OVERLAPPEDWINDOW,CRect(0,0,500,340));
}

I want my dialog appear with dark background that is all area except
my dialog is dark. How to do?
thank you in advance,
