    Rebar not visible

    I am making a paint program and I created a toolbar with my own images that works fine but I tried adding a rebar to it everything compiles fine but only the toolbar shows up not the rebar.

    Code:
     #define NUMBUTTONS 3
    
    HWND CreateToolBar(HWND hWndParent)
    {
    	
    	TBBUTTON buttons[NUMBUTTONS];
    
    	HIMAGELIST himlToolBar = ImageList_LoadImage(
    		m_hInst,
    		MAKEINTRESOURCE(IDB_BITMAP1),
    		16,
    		1,
    		RGB(255, 0, 255),
    		IMAGE_BITMAP,
    		LR_CREATEDIBSECTION);
    
    	
    	hWndToolBar = CreateWindowEx(0, TOOLBARCLASSNAME, NULL,WS_CHILD | WS_VISIBLE |TBSTYLE_FLAT  , 0, 0, 1, 1, hWndParent, NULL, m_hInst, NULL);
    
    	SendMessage(hWndToolBar, TB_SETIMAGELIST, 0, (LPARAM)himlToolBar);
    
    	for(int i = 0; i < NUMBUTTONS; ++i)
    	{
    		buttons[i].iBitmap = i;
    		buttons[i].fsState = TBSTATE_ENABLED;
    		buttons[i].fsStyle = TBSTYLE_BUTTON;
    		buttons[i].dwData = 0L;
    		buttons[i].iString = (INT_PTR)L"New";
    		buttons[i].idCommand = 0;
    	}
    
    	SendMessage(hWndToolBar, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
    
    	SendMessage(hWndToolBar, TB_ADDBUTTONS, (WPARAM)NUMBUTTONS, (LPARAM)&buttons);
    
    	SendMessage(hWndToolBar, TB_AUTOSIZE, 0, 0);
    
    	return hWndToolBar;
    }

    Code:
    HWND CreateRebar(HWND hWndOwner, HWND hWndToolbar)
    {
    	if(hWndToolbar == NULL)
    	{
    		return NULL;
    	}
    
    	INITCOMMONCONTROLSEX icex;
    	icex.dwSize = sizeof(INITCOMMONCONTROLSEX);
    	icex.dwICC = ICC_COOL_CLASSES | ICC_BAR_CLASSES;
    	InitCommonControlsEx(&icex);
    
    	hWndRebar = CreateWindowEx(WS_EX_TOOLWINDOW,
    		REBARCLASSNAME,
    		NULL,
    		WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS |
    		WS_CLIPCHILDREN | RBS_VARHEIGHT |
    		CCS_NODIVIDER | RBS_BANDBORDERS,
    		0, 0, 0, 0,
    		hWndOwner,
    		NULL,
    		m_hInst,
    		NULL);
    
    	if(!hWndRebar)
    	{
    		return NULL;
    	}
    
    	REBARBANDINFO rbBand = { sizeof(REBARBANDINFO) };
    	rbBand.fMask = 
    		RBBIM_STYLE
    		| RBBIM_TEXT
    		| RBBIM_CHILD
    		| RBBIM_CHILDSIZE
    		| RBBIM_SIZE;
    	rbBand.fStyle = RBBS_CHILDEDGE | RBBS_GRIPPERALWAYS;
    
    	DWORD dwBtnSize = (DWORD)SendMessage(hWndToolbar, TB_GETBUTTONSIZE, 0, 0);
    
    	rbBand.lpText = TEXT("");
    	rbBand.hwndChild = hWndToolbar;
    	rbBand.cyChild = LOWORD(dwBtnSize);
    	rbBand.cxMinChild = NUMBUTTONS * HIWORD(dwBtnSize);
    	rbBand.cyMinChild = LOWORD(dwBtnSize);
    
    	rbBand.cx = 0;
    
    	SendMessage(hWndRebar, RB_INSE*****D, (WPARAM)-1, (LPARAM)&rbBand);
    
    	return (hWndRebar);
    
    }

    Code:
    HRESULT InitializeWindow(HINSTANCE hInstance)
    {
    
        HRESULT hr = S_OK;
    	m_hInst = hInstance;
        // Create WIC factory
        hr = CoCreateInstance(
            CLSID_WICImagingFactory,
            NULL,
            CLSCTX_INPROC_SERVER,
            IID_PPV_ARGS(&m_pIWICFactory)
            );
    
        // Register window class
        WNDCLASS wcex;
        if (SUCCEEDED(hr))
        {
    	
            wcex.style         = CS_HREDRAW | CS_VREDRAW;
    		wcex.lpfnWndProc   = (WNDPROC)WndProc;
            wcex.cbClsExtra    = 0;
            wcex.cbWndExtra    = sizeof(LONG_PTR);
            wcex.hInstance     = hInstance;
    		wcex.hIcon         = NULL;
            wcex.hCursor       = LoadCursor(NULL, IDC_ARROW);
    		wcex.hbrBackground = (HBRUSH)::GetStockObject(WHITE_BRUSH);
    		wcex.lpszMenuName  = 0;
            wcex.lpszClassName = L"WICViewerGDI";
           
    
    
          
    
            hr = RegisterClass(&wcex) ? S_OK : E_FAIL;
        }
    
        if (SUCCEEDED(hr))
        {
    
    		
            // Create window
             ghMainWnd = CreateWindow(
                L"WICViewerGDI",
                L"PaintProgram",
                WS_OVERLAPPEDWINDOW | WS_VISIBLE,
                CW_USEDEFAULT,
                CW_USEDEFAULT,
                1920,
                1080,
                NULL,
    			NULL,
                hInstance,
                0
                );
    
    		 hr = ghMainWnd ? S_OK : E_FAIL;
    
    		 ShowWindow(ghMainWnd, SW_SHOW);
    		 UpdateWindow(ghMainWnd);
    
    		 
        }
    
    	CreateRebar(ghMainWnd, hWndToolBar);
    	CreateToolBar(ghMainWnd);
    	
        return hr;
    }

    I cant seem to figure it out any help is appreciated.

    Re: Rebar not visible

    Did you debug your code?
    What does the CreateRebar() function return? Is it, perhaps, NULL? Then you have to call GetLastError to get the extended error information.

    I figured it out it was
    Code:
     REBARBANDINFO rbBand = { sizeof(REBARBANDINFO) };
    the msdn example I followed stated to do it this way but it is older code and someone stated it has to be done like this
    Code:
    REBARBANDINFO rbBand = { sizeof(REBARBANDINFO_V3_SIZE) };
    when used on operating system greater than XP because it doesn't return the same value.

    also I had to set the REBARBANDINFOS'S cbsize variable to REBARBANDINFO_V3_SIZE.

    I swear everytime I follow an example on msdn I always have to spend hours trying to fix the code because it is all older code.



    Thanks anyway.
