I can't see anything when run the Rebar example of MS-SDK (just see the menu
only and nothing else)
Because of that I write a simple rebar but I can't see anything too

All those function is take from Windows SDK
// take from
HWND CreateSimpleToolbar(HWND hWndParent)
{
// Define some constants.
const int ImageListID = 0;
const int numButtons = 3;
const DWORD buttonStyles = BTNS_AUTOSIZE;
const int bitmapSize = 16;

// Create the toolbar.
HWND hWndToolbar = CreateWindowEx(0, TOOLBARCLASSNAME, NULL,
//WS_CHILD | TBSTYLE_WRAPABLE,
WS_CHILD|WS_VISIBLE|TBSTYLE_FLAT|CCS_NOPARENTALIGN|CCS_NORESIZE|CCS_NODIVIDER,
0, 0, 0, 0,
hWndParent, NULL, g_hInst, NULL);
if (hWndToolbar == NULL)
{
return NULL;
}

// Create the imagelist.
HIMAGELIST hImageList = ImageList_Create(
bitmapSize, bitmapSize, // Dimensions of individual bitmaps.
ILC_COLOR16 | ILC_MASK, // Ensures transparent background.
numButtons, 0);

// Set the image list.
SendMessage(hWndToolbar, TB_SETIMAGELIST, (WPARAM)ImageListID,
(LPARAM)hImageList);

// Load the button images.
SendMessage(hWndToolbar, TB_LOADIMAGES, (WPARAM)IDB_STD_SMALL_COLOR,
(LPARAM)HINST_COMMCTRL);

// Initialize button info.
// IDM_NEW, IDM_OPEN, and IDM_SAVE are application-defined command
constants.
TBBUTTON tbButtons[numButtons] =
{
{ MAKELONG(STD_FILENEW, ImageListID), 1, TBSTATE_ENABLED,
buttonStyles, {0}, 0, (INT_PTR)L"New" },
{ MAKELONG(STD_FILEOPEN, ImageListID), 2, TBSTATE_ENABLED,
buttonStyles, {0}, 0, (INT_PTR)L"Open"},
{ MAKELONG(STD_FILESAVE, ImageListID), 3, 0,
buttonStyles, {0}, 0, (INT_PTR)L"Save"}
};

// Add buttons.
SendMessage(hWndToolbar, TB_BUTTONSTRUCTSIZE,
(WPARAM)sizeof(TBBUTTON), 0);
SendMessage(hWndToolbar, TB_ADDBUTTONS, (WPARAM)numButtons,
(LPARAM)&tbButtons);

// Tell the toolbar to resize itself, and show it.
SendMessage(hWndToolbar, TB_AUTOSIZE, 0, 0);
ShowWindow(hWndToolbar, TRUE);
return hWndToolbar;
}

HWND CreateComboBox(HWND hWndParent)
{
HWND hcombo = CreateWindowW(L"COMBOBOX", L"aaa", WS_VISIBLE | WS_CHILD |
CBS_DROPDOWNLIST | WS_VSCROLL | CBS_HASSTRINGS | CBS_AUTOHSCROLL
, 50, 50, 100, 33, hWndParent, 0, g_hInst, 0);
return hcombo;
}

HWND WINAPI CreateRebar(HWND hwndOwner, HWND hwndToolbar, HWND hwndCombo)
{
// Check parameters.
if ((hwndToolbar == NULL) || (hwndCombo == NULL))
{
return NULL;
}

// Initialize common controls.
INITCOMMONCONTROLSEX icex;
icex.dwSize = sizeof(INITCOMMONCONTROLSEX);
icex.dwICC = ICC_COOL_CLASSES | ICC_BAR_CLASSES;
InitCommonControlsEx(&icex);

// Create the rebar.
HWND hwndRebar = CreateWindowEx(WS_EX_TOOLWINDOW,
REBARCLASSNAME,
NULL,
WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS |
WS_CLIPCHILDREN | RBS_VARHEIGHT |
CCS_NODIVIDER | RBS_BANDBORDERS,
0,0,100,100,
hwndOwner,
NULL,
g_hInst,
NULL);

return hwndRebar;
if(!hwndRebar)
{
return NULL;
}

// Initialize band info used by both bands.
REBARBANDINFO rbBand = { sizeof(REBARBANDINFO) };
rbBand.fMask =
RBBIM_STYLE // fStyle is valid.
| RBBIM_TEXT // lpText is valid.
| RBBIM_CHILD // hwndChild is valid.
| RBBIM_CHILDSIZE // child size members are valid.
| RBBIM_SIZE; // cx is valid
rbBand.fStyle = RBBS_CHILDEDGE | RBBS_GRIPPERALWAYS; //RBBS_FIXEDSIZE |

// Get the height of the toolbar.
DWORD dwBtnSize = (DWORD)SendMessage(hwndToolbar, TB_GETBUTTONSIZE, 0,0);

// Set values unique to the band with the toolbar.
rbBand.lpText = TEXT("");
rbBand.hwndChild = hwndToolbar;
rbBand.cyChild = LOWORD(dwBtnSize);
rbBand.cxMinChild = 3 * HIWORD(dwBtnSize);
rbBand.cyMinChild = LOWORD(dwBtnSize);
// The default width is the width of the buttons.
rbBand.cx = 0;

// Add the band that has the toolbar.
SendMessage(hwndRebar, RB_INSERTBAND, (WPARAM)-1, (LPARAM)&rbBand);

// Set values unique to the band with the combo box.
RECT rc;
GetWindowRect(hwndCombo, &rc);
rbBand.lpText = TEXT("Font");
rbBand.hwndChild = hwndCombo;
rbBand.cxMinChild = 0;
rbBand.cyMinChild = rc.bottom - rc.top;
// The default width should be set to some value wider than the text. The
combo
// box itself will expand to fill the band.
rbBand.cx = 100;

// Add the band that has the combo box.
SendMessage(hwndRebar, RB_INSERTBAND, (WPARAM)-1, (LPARAM)&rbBand);

return (hwndRebar);
}

and I call CreateRebar(hWnd, CreateSimpleToolbar(hWnd),
CreateComboBox(hWnd)); on WM_CREATE

can someone tell me what wrong ? The result is a toolbar & a combobox with
no rebar

You're usage of ShowWindow is wrong.

But that's not the real problem. I'm not sure what the real problem is,
but you return from CreateRebar before you add any bands. I'm not sure a
rebar displays anything if it doesn't contain any bands.

I'm using like Microsoft does:
Using Toolbar Controls
http://msdn.microsoft.com/en-us/library/bb760446%28VS.85%29.aspx
(SW_SHOWNORMAL = 1)

I think the ReBar will display when there are
// Add the band that has the toolbar.
SendMessage(hwndRebar, RB_INSERTBAND, (WPARAM)-1, (LPARAM)&rbBand);

What wrong ?

This sample should be fixed then. Okay, TRUE is defined as 1, and so is
SW_SHOWNORMAL, so it's not really a problem. But passing TRUE where a
SW_* constant should be passed is poor style.

Right after creating the rebar control and before inserting any band,
you call "return hwndRebar;".

Oh and try without the WS_EX_TOOLWINDOW style.
