Hi all,

I am trying to create a new window (without border, title bar..etc) for
using brush to make the whole screen become red.

So, anyone knows how to create a new window after pressing a buttom in a
diglog??

Thanks,

I don't know if this helps, but here's a copy of my reply to your previous
thread:

Hi Marks,

Thanks a lot. I can use the code to display red color on the entire
screen.

But, how to create a window, make the size of the screen and retrieves the
device context (DC) for that window?

Hi Tim,

Sorry for the delayed reply. I was out of town all last week.

If you still need an example of creating a full screen colored window,
here's some code...

//-----------------------------------------------------
// FullScreenColorWnd.h
//-----------------------------------------------------

#pragma once
#include "afxwin.h"


// CFullScreenColorWnd

class CFullScreenColorWnd : public CFrameWnd
{
DECLARE_DYNAMIC(CFullScreenColorWnd)

public:
CFullScreenColorWnd();
virtual ~CFullScreenColorWnd();

protected:
DECLARE_MESSAGE_MAP()
virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
public:
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
afx_msg BOOL OnEraseBkgnd(CDC* pDC);
afx_msg void OnLButtonDown(UINT nFlags, CPoint point);

CBrush m_BkgndBrush;
};



//-----------------------------------------------------
// FullScreenColorWnd.cpp
//-----------------------------------------------------

#include "stdafx.h"
#include "FullScreenColorWnd.h"


// CFullScreenColorWnd

IMPLEMENT_DYNAMIC(CFullScreenColorWnd, CFrameWnd)

CFullScreenColorWnd::CFullScreenColorWnd()
{
m_BkgndBrush.CreateSolidBrush(RGB(0xFF,0x00,0x00));
}

CFullScreenColorWnd::~CFullScreenColorWnd()
{
}


BEGIN_MESSAGE_MAP(CFullScreenColorWnd, CFrameWnd)
ON_WM_ERASEBKGND()
ON_WM_LBUTTONDOWN()
ON_WM_CREATE()
END_MESSAGE_MAP()



// CFullScreenColorWnd message handlers



BOOL CFullScreenColorWnd::PreCreateWindow(CREATESTRUCT& cs)
{
BOOL ret = CFrameWnd::PreCreateWindow(cs);

cs.style = WS_VISIBLE | WS_POPUP;
cs.dwExStyle = 0;

return ret;
}

int CFullScreenColorWnd::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;

HDC ScreenDC = ::GetDC(NULL);
MoveWindow(0, 0, ::GetDeviceCaps(ScreenDC, HORZRES),
::GetDeviceCaps(ScreenDC, VERTRES));
::ReleaseDC(NULL, ScreenDC);

return 0;
}

BOOL CFullScreenColorWnd::OnEraseBkgnd(CDC* pDC)
{
CRect CliRect;
GetClientRect(&CliRect);
pDC->FillRect(&CliRect, &m_BkgndBrush);

return TRUE;
}

void CFullScreenColorWnd::OnLButtonDown(UINT nFlags, CPoint point)
{
DestroyWindow();
}



//-----------------------------------------------------
// Example creating the window - click on the window to destroy it
//-----------------------------------------------------

CFullScreenColorWnd *pFullScreenColorWnd = new CFullScreenColorWnd();
pFullScreenColorWnd->Create(NULL, _T(""));
