how to create a new window after pressing a buttom in a diglog??

[=?Utf-8?B?S2Vsdmlu?=]

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

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...

//-----------------------------------------------------
// FullScreenColor Wnd.h
//-----------------------------------------------------

#pragma once
#include "afxwin.h"
// CFullScreenColo rWnd

class CFullScreenColo rWnd : public CFrameWnd
{
DECLARE_DYNAMIC (CFullScreenCol orWnd)

public:
CFullScreenColo rWnd();
virtual ~CFullScreenCol orWnd();

protected:
DECLARE_MESSAGE _MAP()
virtual BOOL PreCreateWindow (CREATESTRUCT& cs);
public:
afx_msg int OnCreate(LPCREA TESTRUCT lpCreateStruct) ;
afx_msg BOOL OnEraseBkgnd(CD C* pDC);
afx_msg void OnLButtonDown(U INT nFlags, CPoint point);

CBrush m_BkgndBrush;
};

//-----------------------------------------------------
// FullScreenColor Wnd.cpp
//-----------------------------------------------------

#include "stdafx.h"
#include "FullScreenColo rWnd.h"
// CFullScreenColo rWnd

IMPLEMENT_DYNAM IC(CFullScreenC olorWnd, CFrameWnd)

CFullScreenColo rWnd::CFullScre enColorWnd()
{
m_BkgndBrush.Cr eateSolidBrush( RGB(0xFF,0x00,0 x00));
}

CFullScreenColo rWnd::~CFullScr eenColorWnd()
{
}
BEGIN_MESSAGE_M AP(CFullScreenC olorWnd, CFrameWnd)
ON_WM_ERASEBKGN D()
ON_WM_LBUTTONDO WN()
ON_WM_CREATE()
END_MESSAGE_MAP ()

// CFullScreenColo rWnd message handlers

BOOL CFullScreenColo rWnd::PreCreate Window(CREATEST RUCT& cs)
{
BOOL ret = CFrameWnd::PreC reateWindow(cs) ;

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

return ret;
}

int CFullScreenColo rWnd::OnCreate( LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnC reate(lpCreateS truct) == -1)
return -1;

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

return 0;
}

BOOL CFullScreenColo rWnd::OnEraseBk gnd(CDC* pDC)
{
CRect CliRect;
GetClientRect(& CliRect);
pDC->FillRect(&CliR ect, &m_BkgndBrus h);

return TRUE;
}

void CFullScreenColo rWnd::OnLButton Down(UINT nFlags, CPoint point)
{
DestroyWindow() ;
}

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

CFullScreenColo rWnd *pFullScreenCol orWnd = new CFullScreenColo rWnd();
pFullScreenColo rWnd->Create(NULL, _T(""));
