如果 winapi window 已最小化，我该如何恢复它？

Question

我试过很多函数，比如ShowWindow & IsWindowVisible 至少尝试给出window最小化的结果，更不用说还原了。无论 window 是否被最小化，这些函数总是 return false。我也尝试过将 GetWindowPlacement 与 SetWindowPlacement 一起使用，但没有成功。我的 HWND 发现 Chrome 和 FindWindow(TEXT("Chrome_WidgetWin_1"), NULL); 是成功的，但我想 test/restore window 如果它被最小化并且过去 10 小时没有任何显示它。

Chrome 有一个不可见的 window 同名。不可见的 window 只需跳过即可。

void show(HWND hwnd)
{
    //We can just call ShowWindow & SetForegroundWindow to bring hwnd to front. 
    //But that would also take maximized window out of maximized state. 
    //Using GetWindowPlacement preserves maximized state
    WINDOWPLACEMENT place;
    memset(&place, 0, sizeof(WINDOWPLACEMENT));
    place.length = sizeof(WINDOWPLACEMENT);
    GetWindowPlacement(hwnd, &place);

    switch (place.showCmd)
    {
    case SW_SHOWMAXIMIZED:
        ShowWindow(hwnd, SW_SHOWMAXIMIZED);
        break;
    case SW_SHOWMINIMIZED:
        ShowWindow(hwnd, SW_RESTORE);
        break;
    default:
        ShowWindow(hwnd, SW_NORMAL);
        break;
    }

    SetForegroundWindow(hwnd);
}

int WINAPI WinMain(HINSTANCE hinst, HINSTANCE, LPSTR cmdline, int nshow)
{
    const wchar_t *classname = L"Chrome_WidgetWin_1";

    HWND hwnd = NULL;
    for (;;)
    {
        hwnd = FindWindowEx(0, hwnd, classname, 0);
        if (!hwnd) break;

        //skip Chrome's invisible winodw
        if (IsWindowVisible(hwnd))
        {
            wchar_t buf[260];
            GetWindowText(hwnd, buf, 260);
            OutputDebugString(buf);
            OutputDebugString(L"\n");

            show(hwnd);
            break;
        }
    }

    return 0;
}
