MFC: Easier way to know which Edit Control has the focus?
-
Hi, In my program, I have 56 Edit Controls where I can type the names of 56 players. Presently, I'm using ON_EN_SETFOCUS for every Edit Control to set an INT variable that tells me which Edit Control has the focus. When I want to print, delete or view the result of the player in focus, I check the variable and than print or delete the good player. Is there an easier way to know the ID of the Edit Control in focus? Like when I want to print a player's results, just get the Edit Control ID in focus at this moment, compare the ID and identify the player. Here's a sample of my code: .... ON_EN_SETFOCUS(IDC_NAME13, OnEnSetfocusName13) ON_EN_SETFOCUS(IDC_NAME14, OnEnSetfocusName14) END_MESSAGE_MAP() void CMainView::OnEnSetfocusName14() { PlayerInFocus = 14; } What I would like to do: void CMainView::OnPrintPlayer() { Get the control ID in focus if(Control ID == 14) Print Player 14 else if(Control ID == 15) Print Player 15 else if ... } Thanks Dave

just make sure your resource ID`s are in consecutive eg IDC_NAME1=21 IDC_NAME2=22 . . . IDC_NAME26=46 and then you could use in messagemap: ON_NOTIFY_RANGE( NM_SETFOCUS, IDC_NAME1, IDC_NAME26, SetPlayerFocus ) define SetPlayerFocus in header as: afx_msg void SetPlayerFocus(UINT nid, NMHDR* pNotifyStruct, LRESULT* pResult); void CMainView::SetPlayerFocus(UINT nid, NMHDR* pNotifyStruct, LRESULT* pResult) { m_nPlayerWithFocus = nid - IDC_NAME1 +1 ; //results in 1 for player1 etc... pResult = 0; } void CMainView::OnPrintPlayer() { // print whatever you like, m_nPlayerWithFocus contains value of last edit field that had focus } I think that should roughly do the trick... . . . . other option, maybe even better skip the setfocus function just do: void CMainView::OnPrintPlayer() { CWnd * wndFoc = GetFocus(); if( !wndFoc ) return; int nCurrentPlayer = wndFoc->GetDlgCtrlID() - IDC_NAME1 +1; if( 0=nCurrentPlayer ) PrintResultsFor(nCurrentPlayer); }

As a note, you could use: CWnd *pFocus = GetFocus(); if (pFocus && pFocus->IsKindOf(RUNTIME_CLASS(CEdit))) { UINT id = pFocus->GetDlgCtrlID(); // makse use of the controls id here....

Maybe I'm missing something, but why can't you just
GetFocus()? This will return aCWnd*of the window having the focus.
