1.讀取單個文件路徑spa
1 Invalidate(); 2 3 CFileDialog dlg(TRUE, NULL, NULL, OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_READONLY, 4 TEXT("Supported Types (*.jpg;*.png;*.gif;*.bmp;...)|*.jpg;*.png;*.gif;*.bmp|Tiff(*.tiff;*.tif)|*.tiff;*.tif|All Files(*.*)|*.*||"), NULL); 5 dlg.m_ofn.nFilterIndex = 1; 6 dlg.m_ofn.hwndOwner = m_hWnd; 7 dlg.m_ofn.lStructSize = sizeof(OPENFILENAME); 8 dlg.m_ofn.lpstrTitle = TEXT("Opening Image...\0"); 9 dlg.m_ofn.nMaxFile = MAX_PATH; 10 if (dlg.DoModal() == IDOK) 11 { 12 m_path = dlg.GetPathName(); 13 m_isOpen = TRUE; 14 UpdateData(FALSE); 15 } 16 else 17 return; 18 //左邊圖片控件顯示圖片 19 char* s_path; 20 USES_CONVERSION; 21 s_path = T2A(m_path);
2.讀取多個文件的文件名code
1 vector<CString>fileDict;
CFileDialog dlg(TRUE, _T("*"), NULL, OFN_ALLOWMULTISELECT | OFN_FILEMUSTEXIST, _T("全部文件 file (*.*)|*.*||"), NULL); 2 DWORD MAXFILE = 500 * MAX_PATH;// 最多打開500個文件 3 dlg.m_ofn.nMaxFile = MAXFILE; 4 TCHAR* buf = new TCHAR[MAXFILE]; 5 memset(buf, 0, sizeof(TCHAR) * MAXFILE); 6 dlg.m_ofn.lpstrFile = buf; 7 8 int iReturn = dlg.DoModal(); 9 if (iReturn == IDCANCEL) 10 { 11 return; 12 } 13 POSITION pos = dlg.GetStartPosition(); 14 while (pos != NULL) 15 { 16 fileDict.push_back(dlg.GetNextPathName(pos)); 17 } 18 19 delete[] buf;
}
3.選擇文件夾路徑blog
1 CString m_saveFilePath; 2 TCHAR szPath[_MAX_PATH]; 3 BROWSEINFO bi; 4 bi.hwndOwner = GetSafeHwnd(); 5 bi.pidlRoot = NULL; 6 bi.lpszTitle = _T("請選擇圖片路徑"); 7 bi.pszDisplayName = szPath; 8 bi.ulFlags = BIF_RETURNONLYFSDIRS; 9 bi.lpfn = NULL; 10 bi.lParam = NULL; 11 12 LPITEMIDLIST pItemIDList = SHBrowseForFolder(&bi); 13 if (pItemIDList) 14 { 15 if (SHGetPathFromIDList(pItemIDList, szPath)) 16 { 17 m_saveFilePath = szPath; 18 m_saveFilePath = m_saveFilePath + _T("\\"); 19 } 20 21 //use IMalloc interface for avoiding memory leak 22 IMalloc* pMalloc; 23 if (SHGetMalloc(&pMalloc) != NOERROR) 24 { 25 TRACE(_T("Can't get the IMalloc interface\n")); 26 } 27 28 pMalloc->Free(pItemIDList); 29 if (pMalloc) 30 pMalloc->Release(); 31 UpdateData(FALSE); 32 }
