Q: How to join the toolbar in the dialog box to add the following code in OnInitDialog:

Bool cyordlg :: oninitdialog ()

{

CDIALOG :: OnInitdialog ();

// Create the Toolbar. To understand the meaning of the styles buy, you

// CAN Take a look at the msdn for the create function of the ctoolbar class.

Toolbar.create (this, ws_child | ws_visible | cbrs_top | CBRS_Tooltips | CBRS_FLYBY | CBRS_BORDER_BOTTOM);

// i Have Assumed That You Have Named Your Toolbar's Resource AS iDR_Toolbar1.

// if you have given it a different name, change the line bellow to accessate

// That by changing the parameter for the loadtoolbar function.

Toolbar.LoadToolbar (IDR_Toolbar1);

CRECT RCCLIENTSTART;

CRECT RCCLIENTNOW;

GetClientRect (rcclientstart);

// to reposition and resize the control bar

Repositionbars (AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0, REPOSQUERY, RCCLIENTNOW);

Cpoint ptoffset (RcClientst, RcClientStart.Left, RcClientnow.top-rcclientstart.top);

CRECT RCCHILD;

CWND * PWNDCHILD = GetWindow (GW_CHILD);

While (PWNDCHILD)

{

PWNDCHILD-> GetWindowRect (rcchild);

ScreenToClient (RCCHILD);

RcChild.offsetRect (PTOFFSET);

PWNDCHILD-> MoveWindow (RcChild, False);

PWNDCHILD = PWNDCHILD-> getNextWindow ();

}

CRECT RCWINDOW;

GetWindowRect (rcwindow);

RcWindow.right = rcclientstart.width () - rcclientnow.width ();

RcWindow.bottom = rcclientstart.height () - rcclientnow.Height ();

MoveWindow (RCWindow, False);

// and position the control bars

Repositionbars (AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);

Return True; // Return True UnsS you set the focus to a control

}

Q: How to change the shape of the dialog? Available in some of the following: CreatePolygonRGN CreateRectrGN CreateroundRectRGN et al. CRGN M_RGN; // Put this in your dialog's header file. I. A Member Variable

// this gets the size of the dialog: this basce of code is to be placed in the

// OnInitdialog Function of Your Dialog.

CRECT RCDIALOG

GetClientRect (rcdialog);

// the folowing code creates the area and assigns it to your dialog. Item / ASSIGNS IT TO YOROG

M_Rgn.createellLipTicRGN (0, 0, RcDialog.width (), RCDialogHeight ());

SetwindowRgn (GetSafehWnd (), (hrgn) m_RGN, TRUE);

Q: How do I achieve non-customer movement? Use the following two methods:

// Handler for WM_LButtondown Message

Void CyourDialog :: ONLBUTTONDOWN (uint nflags, cpoint point)

{

CDIALOG :: ONLBUTTONDOWN (NFLAGS, POINT);

Postmessage (WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM (Point.x, Point.y);

}

// Handler for WM_NCHITTEST MESSAGE

Long cyoRDialog :: Onnchnittest (Uint Uparam, Long Lparam)

{

INT xpos = loword (lparam);

Int Ypos = HiWord (LPARAM);

Uint nhittest = cdialog :: ONNCHITTEST (CSIZE (XPOS, YPOS));

Return (nhittest == htclient)? htcaption: nhittest;

}

Q: How to make the dialog initially minimize the state? Add the following code in OnInitDialog:

SendMessage (WM_SYSCOMMAND, SC_MAXIMIZE, NULL);

Q: How to limit the dialog size range? Add the following code in WM_SIZING:

Void CyourDialog :: Onsizing (uint fwside, lprect prect)

{

IF (prect-> right - prect-> left <= 200)

Prect-> Right = prect-> left 200;

IF (prect-> bottom - prect-> TOP <= 200)

prect-> bottom = prect-> top 200;

CDIALOG :: Onsizing (fwside, prect);

}

Q: How do I join the status bar in the dialog? Define the cstatusbar variable:

CSTATUSBAR M_STATUSBAR;

Define status bar specified:

Static uint based_code indeicators [] =

{

ID_indicator_caps,

ID_indicator_num

}

Add the following code in OnInitDialog: m_statusbar.createex (this, sbt_tooltips, ws_child | ws_visible | cbrs_bottom, afx_idw_status_bar);

// set the indeicators namely caps and nums loc status

m_statusbar.setindicators (Indicators, Sizeof (Indicators) / SizeOf (UINT));

CRECT RECT;

GetClientRect (& RECT);

M_StatusBar.SetPaneInfo (0, ID_indicator_caps, sbps_normal, reference.width () / 2);

m_statusbar.SetPaneInfo (1, ID_indicator_num, sbps_stretch, rect.width () / 2);

Repositionbars (AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, ID_IDICATOR_NUM);

m_statusbar.getStatusbarCtrl (). setbkcolor (RGB (180, 180, 180));
