Desable VK_DELETE accelerator key while Editing Tree conrol's Item Label

Problem/Bug :  User cannot delete characters with Delete key.

Technical Details: In our application user can delete items in a Tree control. Say this menu COMMAND is ID_FILE_DELETE and its corresponding accelerator key is VK_DELETE. This tree control is created with  TVS_EDITLABELS style.

Behavior: VK_DELETE accelerator key method is invoking while editing HTREEITEM in CTreeCtrl.

Solution 1: Add following code in PreTranslateMessage

// Header file CLeftView.h class CLeftView : public CTreeCtrl {       virtual BOOL PreCreateWindow(CREATESTRUCT& cs); }; // Header file CLeftView.cpp BOOL CLeftView::PreTranslateMessage(MSG* pMsg) {       // A pointer to the edit control used to edit the item text, if successful;otherwise NULL       if (__super::GetEditControl())       {             ::TranslateMessage(pMsg);             ::DispatchMessage(pMsg);             return TRUE;       }       return CTreeView::PreTranslateMessage(pMsg); }

Solution 2: by avoid calling GetEditControl() every time

// Header file CLeftView.h class CLeftView : public CTreeCtrl { public:       virtual BOOL PreCreateWindow(CREATESTRUCT& cs); protected:       DECLARE_MESSAGE_MAP()       afx_msg void OnTvnBeginlabeledit(NMHDR *pNMHDR, LRESULT *pResult);       afx_msg void OnTvnEndlabeledit(NMHDR *pNMHDR, LRESULT *pResult); private:       bool m_bEditLabel; }; // Source file CLeftView.cpp CLeftView::CLeftView() {       m_bEditLabel = false; } BEGIN_MESSAGE_MAP(CLeftView, CTreeCtrl)       ON_NOTIFY_REFLECT(TVN_BEGINLABELEDIT, &CDMTreeCtrl::OnTvnBeginlabeledit)      ON_NOTIFY_REFLECT(TVN_ENDLABELEDIT, &CDMTreeCtrl::OnTvnEndlabeledit) END_MESSAGE_MAP() void CLeftView::OnTvnBeginlabeledit(NMHDR *pNMHDR, LRESULT *pResult) {       LPNMTVDISPINFO pTVDispInfo = reinterpret_cast<LPNMTVDISPINFO>(pNMHDR);       m_bEditLabel = true;       *pResult = 0; } void CLeftView::OnTvnEndlabeledit(NMHDR *pNMHDR, LRESULT *pResult) {       LPNMTVDISPINFO pTVDispInfo = reinterpret_cast<LPNMTVDISPINFO>(pNMHDR);       m_bEditLabel = false;       // TODO: Add your control notification handler code here       *pResult = 0; } BOOL CLeftView::PreTranslateMessage(MSG* pMsg) {       if( m_bEditLabel)       {             ::TranslateMessage(pMsg);             ::DispatchMessage(pMsg);             return TRUE;       }       return CTreeView::PreTranslateMessage(pMsg); }

Solution 2: I am thinking.
