Hello All.
I need to set the focus by pressing "TAB" manually.
I have a problem when manually switching control focus using function SetFocus.
"Focus Rect" does't show.
If I use the default function then the "Focus Rect" is drawn.

What should be done to make the "Focus Rect" was painted?

You may call RedrawWindow() after SetFocus().

Hi. Your question is not clear to me.
- You say that You need to set focus by pressing "TAB" manually: do you mean that the final user will simply hit the TAB key?
- You say that SetFocus does not work as expected, but the "default function" is working. What is this default function?

I know how to do this for the user control.
I want to draw "Focus rect" on any standard control(Button, ComboBox etc.) without reimplementing draw function.

HWND SetFocus(HWND hWnd) function set the focus at window, and DRAWITEMSTRUCT struct has member variable for item state.

CSS

typedef struct tagDRAWITEMSTRUCT {
    UINT CtlType;
    UINT CtlID;
    UINT itemID;
    UINT itemAction;
    UINT itemState;
    HWND hwndItem;
    HDC hDC;
    RECT rcItem;
    ULONG_PTR itemData;
} DRAWITEMSTRUCT;

C++

void CMyControl::DrawItem(LPDRAWITEMSTRUCT lpDIS) 
{
	CDC* pDC = CDC::FromHandle(lpDIS->hDC);

	BOOL bIsFocus = (lpDIS->itemState & ODS_FOCUS);
...

DRAWITEMSTRUCT itemstate[^]

I did it.
All controls necessary to send the WM_UPDATEUISTATE message, before calling SetFocus function.
The focus frame will be displayed correctly.

Example:
::SendMessage(hWnd, WM_UPDATEUISTATE, MAKEWPARAM(UIS_CLEAR, UISF_HIDEFOCUS), NULL);
