#define LOGIN_BTN 5
#define LOGOUT_BTN 6
class CMainFrame: public CFrameWnd
{
CPoint mCoordinate;
CSize mDimension;
public:
CMainFrame()
{
// Get primary screen resolution
int widthScreen = GetSystemMetrics(SM_CXSCREEN);
int heightScreen = GetSystemMetrics(SM_CYSCREEN);
// Set size and position to middle screen
mDimension.cx = 280;
mDimension.cy = 133;
mCoordinate.x = (widthScreen / 2) - (mDimension.cx / 2);
mCoordinate.y = (heightScreen / 2) - (mDimension.cy / 2);
Create(
NULL,
"Pandora",
WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU,
CRect(mCoordinate, mDimension));
};
void render()
{
CButton* loginBtn = new CButton();
loginBtn->Create(
"Login",
WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
CRect(CPoint(100, 60), CSize(150, 25)),
this, LOGIN_BTN);
};
void removeAllChild()
{
CWnd* pChild = nullptr;
while(true)
{
pChild = GetWindow(GW_CHILD);
if(pChild == NULL) { break; }
delete pChild;
};
};
protected:
afx_msg int OnCreate(LPCREATESTRUCT);
afx_msg void login();
afx_msg void logout();
DECLARE_MESSAGE_MAP()

BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
ON_WM_CREATE()
ON_COMMAND(LOGIN_BTN, &CMainFrame::login)

// How to make this logout button such it in 2nd page?
CButton* logoutBtn = new CButton;

this, LOGOUT_BTN);
};
void CMainFrame::logout()
{
removeAllChild();
render();
};
class CApplication : public CWinApp {
BOOL InitInstance() {
CMainFrame* mainWnd = new CMainFrame();

You could refer to the document : Adding Multiple Views to a Single Document. Also here is a similar thread may help: How to change MFC View by clicking a Button inside the MainFrame.
You could use the code below to switch the view:
pActiveView->ShowWindow(SW_HIDE);
pNewView->ShowWindow(SW_SHOW);
((CFrameWnd *)m_pMainWnd)->SetActiveView(pNewView);
((CFrameWnd *)m_pMainWnd)->RecalcLayout();
pNewView->Invalidate();
