本文所述實(shí)例主要實(shí)現(xiàn)了刪除某個(gè)盤符下指定位置的文件,可以是TXT、doc、jpeg等格式,只要選定格式后,再定義好盤符,即可一鍵刪除所有指定類型的文件。再次提示刪除前請確認(rèn),且刪除后不可恢復(fù)。
以下是最主要的核心代碼,其它代碼讀者可以自己添加。
SHFILEINFO shInfo;memset(&shInfo,0,sizeof(SHFILEINFO));HIMAGELIST hImage = (HIMAGELIST)SHGetFileInfo("C://",0,&shInfo, sizeof( SHFILEINFO ), SHGFI_SYSICONINDEX | SHGFI_SMALLICON );m_ImageList.Attach(hImage); m_ComboEx.SetImageList(&m_ImageList);m_ComboEx.ResetContent();char pchDrives[128] = {0};char* pchDrive;GetLogicalDriveStrings(sizeof(pchDrives), pchDrives); //列舉盤符pchDrive = pchDrives;int nItem = 0;while(*pchDrive){ COMBOBOXEXITEM cbi; CString csText; cbi.mask = CBEIF_IMAGE|CBEIF_INDENT|CBEIF_OVERLAY| CBEIF_SELECTEDIMAGE|CBEIF_TEXT; SHFILEINFO shInfo; //定義文件信息 int nIcon; SHGetFileInfo(pchDrive, 0, &shInfo, sizeof(shInfo), SHGFI_ICON|SHGFI_SMALLICON); //獲取系統(tǒng)文件圖標(biāo) nIcon = shInfo.iIcon; //設(shè)置COMBOBOXEXITEM結(jié)構(gòu) cbi.iItem = nItem; cbi.pszText = pchDrive; cbi.cchTextMax = strlen(pchDrive); cbi.iImage = nIcon; cbi.iSelectedImage = nIcon; cbi.iOverlay = 0; cbi.iIndent = (0 & 0x03); m_ComboEx.InsertItem(&cbi); //插入數(shù)據(jù) nItem++; pchDrive += strlen(pchDrive) + 1; } return TRUE; // return TRUE unless you set the focus to a control}void CDeleteDlg::OnSysCommand(UINT nID, LPARAM lParam){ if ((nID & 0xFFF0) == IDM_ABOUTBOX) { CAboutDlg dlgAbout; dlgAbout.DoModal(); } else { CDialog::OnSysCommand(nID, lParam); }}void CDeleteDlg::OnPaint() { if (IsIconic()) { CPaintDC dc(this); // device context for painting SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0); // Center icon in client rectangle int cxIcon = GetSystemMetrics(SM_CXICON); int cyIcon = GetSystemMetrics(SM_CYICON); CRect rect; GetClientRect(&rect); int x = (rect.Width() - cxIcon + 1) / 2; int y = (rect.Height() - cyIcon + 1) / 2; // Draw the icon dc.DrawIcon(x, y, m_hIcon); } else { CDialog::OnPaint(); }}HCURSOR CDeleteDlg::OnQueryDragIcon(){ return (HCURSOR) m_hIcon;}void CDeleteDlg::DelFile(CString path,CString name){ CString strtemp; if (path.Right(1) != "http://") //判斷路徑是否以/結(jié)尾 strtemp.Format("%s//*.*",path);//設(shè)置通配符 else strtemp.Format("%s*.*",path);//設(shè)置通配符 CFileFind findfile; BOOL bfind = findfile.FindFile(strtemp);//查找文件 while (bfind)//循環(huán)查找 { bfind = findfile.FindNextFile();//查找下一個(gè)文件 if(!findfile.IsDots() && !findfile.IsDirectory()) { CString str = findfile.GetFileName(); int index = str.ReverseFind('.'); if(str.Right(str.GetLength()-index) == name) { DeleteFile(findfile.GetFilePath()); } } else if (findfile.IsDots()) { continue; } else if (findfile.IsDirectory())//如果是目錄 { DelFile(findfile.GetFilePath(),name);//遞歸查找 } }}void CDeleteDlg::OnButdelete() { // TODO: Add your control notification handler code here CString path,name; m_ComboEx.GetWindowText(path); m_ExName.GetWindowText(name);//獲得文件擴(kuò)展名 DelFile(path,name); MessageBox("已刪除指定類型文件!");}
這里省去了窗體部分的代碼,進(jìn)行過VC開發(fā)的朋友應(yīng)該可以看得懂的。
