Problem with Frame control about winfbe HOT 2 OPEN

That is not how Frame controls work in pure Win32 API programming. I know what you are saying though because what you describe is the way it works in environments like Visual Basic where a "Frame" control is actually a container that can encapsulate child controls and then when the Frame moves, the children move also. However, in normal Win32 API programming, a Frame control is no different than any other Window. I would have to build the parent-child relationship into WinFBE Frames because it does not come standard with the regular Windows Frame window (which is basically a STATIC class window with some special Window styles to give it the frame look).

How about programming a GroupBox. is a container control.
A group box is a special kind of a button created with the BS_GROUPBOX style.
CreateWindowW(L"Button", L"Choose colour",
WS_CHILD | WS_VISIBLE | BS_GROUPBOX,
10, 10, 120, 110, hwnd, (HMENU) 0, g_hinst, NULL);
