Thanks Ron,

i observed something weird. i created a pointer to the toolbar and
implemented toolbar as like this

int CParentFrame::CreateAndDockToolBar(void){
    DWORD dToolBarStyle;
    dToolBarStyle = TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP |
CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC;
    if (!m_wndToolBar.CreateEx(this, dToolBarStyle) ||
        !m_wndToolBar.LoadToolBar(IDR_MAINFRAME1)){
        TRACE0("Failed to create toolbar\n");
        return -1; // fail to create
    }
    m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
    EnableDocking(CBRS_ALIGN_ANY);
    RecalcLayout(TRUE);
    DockControlBar(&m_wndToolBar);
    return 0;
}
int CParentFrame::OnCreate(LPCREATESTRUCT lpCS){

    pMenu = new CMenu();
    pMenu->LoadMenu("MAINMENU");
    CreateClient(lpCS,pMenu->GetSubMenu(0));
    //m_wndToolBar = new CToolBar();

    if (!m_wndStatusBar.Create(this) ||!
m_wndStatusBar.SetIndicators(indicators, sizeof(indicators)/
sizeof(UINT))){
        TRACE0("Failed to create status bar\n");
        return -1; // fail to create
    }

    // TODO: Delete these three lines if you don't want the toolbar to
    // be dockable

    return CreateAndDockToolBar();
}

i call CreateAndDockToolBar from OnCreate function.

when the member variable m_wndToolBar is a pointer, i created a new
CToolbar and after resizing the window, the toolbar again disappeared,
and i found that
the address of the variable was NULL.
how is that possible.
also please somebody tell me, whether this is a wrong way to create
and dock a toolbar to my application

thanks

jc

I don't use MFC and I'm using VC++ 6, but maybe you have to handle the
WM_SIZE message.
In MFC, it would be something like an OnSize() or similar function.
You may have to manually resize and move it.

I use a Rebar that I resize every time the window is resized and the
function looks like this ...

//ghWnd is the main application's window

void MoveRebar(HWND hWnd)
{
RECT rc,rcRebar;
int x,y,cx,cy;

GetClientRect(ghWnd, &rc);
GetWindowRect(GetDlgItem(hWnd, ID_REBAR), &rcRebar);

switch(g_wSide) {
default:
case TOP:
  //align the rebar along the top of the window
  x = 0;
  y = 0;
  cx = rc.right - rc.left;
  cy = rcRebar.bottom - rcRebar.top;
  break;

case LEFT:
  //align the rebar along the left side of the window
  x = 0;
  y = 0;
  cx = rcRebar.right - rcRebar.left;
  cy = rc.bottom - rc.top;
  break;

case BOTTOM:
  //align the rebar along the bottom of the window
  x = 0;
  y = rc.bottom - ((rcRebar.bottom - rcRebar.top));
  cx = rc.right - rc.left;
  cy = rcRebar.bottom - rcRebar.top;
  break;

case RIGHT:
  //align the coolbar along the right side of the window
  x = rc.right - (rcRebar.right - rcRebar.left);
  y = 0;
  cx = rcRebar.right - rcRebar.left;
  cy = rc.bottom - rc.top;
  break;
}

MoveWindow( GetDlgItem(hWnd, ID_REBAR),
    x,
    y,
    cx,
    cy,
    TRUE);
//workaround, have to maximize last toolbar else it is right justified
SendMessage(ghRebar,RB_MAXIMIZEBAND,(WPARAM)4,(LPARAM)0);

}

I hope that this give you something to work with, or that someone working
with MFC answers your post.

i have specific way to reproduce the problem.
it happens only in release mode.
the toolbar disappear when i change the size of the window to which it
has been attached.
like maximize, minimize or even change the size.

thanks

i created a win32 application
the parentframe is CMDIFrameWnd and it has a lot of CMDIChildWnd
attached to it.
i also create a toolbar resource and docked it to the main frame.
when i open the application(in release mode),
minimize or maximize or even restore, tool bar disappears. even if try
to open a file(using CFileDialog class)
toolbar disappears.
can somebody explain why it happens and how to prevent it from
happening again

it is VC++ project created in Visual Studio 2005 or VC8

thanks
