当我移动跟踪栏时，如何防止控件(选项卡）闪烁和消失与Windows通用控件6.0?
How to prevent controls( tabs ) from blinking and disappearing with windows common controls 6.0 when I move a trackbar?
滑动跟踪栏并释放鼠标按钮时，整个窗口闪烁，选项卡消失。
当我使用旧版本时，一切正常！
当我使用新的 Microsoft Windows 公共控件 v.6.0 时，观察到此问题!!

这就是整个程序。
我举一个紧凑的例子。
如果你运行它，你会看到问题。
如果注释新控件，问题将消失。
选项卡控件公共控件不会为您管理单独的内容窗格，因此，如果您希望该跟踪栏是按我们希望选项卡控件的工作方式工作的选项卡控件的子项，则需要自行管理子窗格。
您可以使用"TabCtrl_AdjustRect"来确定子窗格需要多大。请参阅以下代码修改，例如：
#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
);
}
LRESULT CALLBACK WndProcedure(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam) {
switch (Msg) {
case WM_CREATE: {
HINSTANCE hInst = GetModuleHandle(NULL);
RECT rc; int dx, dy;
GetClientRect(hWnd, &rc);
dx = rc.right - rc.left;
dy = rc.bottom - rc.top;
TCITEM tie = {
TCIF_TEXT | TCIF_IMAGE,
0, 0,
NULL,
0, -1, 0
};
hTab = CreateWindowEx(NULL, WC_TABCONTROL, _T(""),
WS_VISIBLE | WS_CHILD | WS_CLIPSIBLINGS,
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");
TabCtrl_InsertItem(hTab, 1, &tie);
for (int i = 0; i < 2; i++)
g_tabPanes[i] = CreateTabPane(hTab, TAB_ID + i, hInst);
CreateWindowEx(NULL, TRACKBAR_CLASS, _T(""), WS_VISIBLE | WS_CHILD | WS_TABSTOP,
50, 50, 200, 40, g_tabPanes[0], (HMENU)1002, hInst, NULL);
}
break;
case WM_NOTIFY: {
LPNMHDR ns = (LPNMHDR)lParam;
