When sliding the trackbar and release the mouse button, the whole window flashes and the tabs dissappear.
When I use the old version, everything works properly!
When I use the new Microsoft Windows Common Controls ver.6.0, this problem is observed !!!

That's the whole program.
I give a compact example.
If you run it, you will see the problem.
If you comment the new controls, the problem will disappear.
The tab control common control is not going to manage separate content panes for you, so if you want that track bar to be a child of the tab control that works in the way we expect a tab control to work, you need to manage child panes yourself.
You can use "TabCtrl_AdjustRect" to figure out how big the child panes need to be. See the following modification of your code, for example:
#define TAB_ID 2000
HWND hWin, hTab;
HWND g_tabPanes[2];
HWND CreateTabPane(HWND tabctrl, int id, HINSTANCE instance)
{
RECT rcTab;
GetClientRect(tabctrl, &rcTab);
TabCtrl_AdjustRect(tabctrl, FALSE, &rcTab);
int wd = rcTab.right - rcTab.left;
int hgt = rcTab.bottom - rcTab.top;
return CreateWindow(
L"static", L"",
WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS,
rcTab.left, rcTab.top, wd, hgt,
tabctrl,
(HMENU) id,
instance,
NULL
);
}

TCITEM tie = {
TCIF_TEXT | TCIF_IMAGE,
0, 0,
NULL,
0, -1, 0

hTab = CreateWindowEx(NULL, WC_TABCONTROL, _T(""),

0, 0, dx, dy, hWnd,
(HMENU)1001, hInst, NULL
);
tie.pszText = (LPWSTR)_T("Tab One");
TabCtrl_InsertItem(hTab, 0, &tie);
tie.pszText = (LPWSTR)_T("Tab Two");
