This function sends the BACK key to the control with focus.
After an application overrides the BACK key by sending the SHCMBM_OVERRIDEKEY message to its menu bar, the BACK key message is received as a WM_HOTKEY message. Pass the WM_HOTKEY message and its wParam and lParam values to the application to forward the BACK key to child windows.
void SHSendBackToFocusWindow( UINT uMsg, WPARAM wp, LPARAM lp );
- The WM_HOTKEY message.
- The wParam of the WM_HOTKEY message.
- The lParam of the WM_HOTKEY message. HIWORD contains the virtual key code of the overridden key; LOWORD contains information about the modifier keys or MOD_KEYUP if the key was released.
