I try to create Window for video by using following syntax:

```
hwnd=CreateWindow("Video Window", "Video window", 
                    WS_OVERLAPPEDWINDOW | WS_VISIBLE,
        CW_USEDEFAULT, CW_USEDEFAULT, rect.right-rect.left,rect.bottom-rect.top,        NULL, NULL, hInstance, NULL);

```

All works as expected but the issue is that the window always on top. It means that I see this window even if I switch to other application.

From `Window directive` program I found additional style: `WS_EX_TOPMOST`

How can I remove It programmatically or do I need override it somehow?

I tried `SetWindowPos`:

```
SetWindowPos(hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

```

or to use instead `CreateWindow` at `CreateWindowEx`:

```
hwnd=CreateWindowEx(WS_EX_LEFT | WS_EX_LTRREADING | WS_EX_RIGHTSCROLLBAR | WS_EX_WINDOWEDGE,
                    "Video Window","Video Window",
                    WS_OVERLAPPEDWINDOW  | WS_VISIBLE ,
                    CW_USEDEFAULT,
                    CW_USEDEFAULT,
                    rect.right-rect.left,
                    rect.bottom-rect.top,
                    NULL,
                    NULL,
                    hInstance,
                    NULL);

```

but still get flag `WS_EX_TOPMOST`

Thanks,
