Write registry management programs with VC6 (2)
Solarsoft 1. Use a tree to display the registry information. Note: The registry information is more, it is impossible to display all, then you can first display the closest to the tree root, and then gradually display the scheme of the subtree according to the operation, 1) Initialize the tree void CregEftView :: OnInitialupdate ) {CTreeView :: OnInitialUpdate (); / * define TreeCtrl icon * / m_pImageList = new CImageList (); CWinApp * pApp = AfxGetApp (); ASSERT (m_pImageList = NULL);! m_pImageList-> Create (16, 16, ILC_COLOR8 | ILC_MASK, 9, 9); m_pimagelist-> add (PAPP-> Loadicon); m_pimagelist-> add (PAPP-> Loadicon (ICO_OpenFLD)); m_pimagelist-> add (PAPP-> Loadicon (ICO_CLSDFLD)); GetTreeCtrl () SetImageList (m_pImageList, TVSIL_NORMAL);.. HTREEITEM hParent = GetTreeCtrl () InsertItem (MYCOMPUTER, ILI_MYCOMP, ILI_MYCOMP); // display roots, MYCOMPUTER macro is defined as "my computer" InitTreeView (hParent); // initialize primary key GetTreeCtrl () Expand (hParent, TVE_EXPAND);.} void CRegLeftView :: InitTreeView (HTREEITEM hParent) {HTREEITEM hItem; for (int i = 0; i <6; i ). {hItem = GetTreeCtrl () InsertItem (HKey_Root [ I], ILI_CLSDFLD, ILI_OPENFLD, HPAR ENT); AdddumMynode (HITEM); // Add Identification Tree}} 2) Send Tree View Message TVN_ItemExPanding and TVN_SelChanging Writing, the former is extension (or shrink), the latter changes the current selection.
