  5. * DLL functions to get summary info from OLE 2.0 document files.
  6. *
  7. *     Copyright ⌐ 1994 Frank F Ramos, All Rights Reserved
  8. *     Send problem reports and comments to 72202.2574@compuserve.com
  9. *            
  10. * Compile using CPPSUM.H
  11. * Link using CPPSUM.LIB
  12. * CPPSUM.DLL should be placed in \WINDOWS\SYSTEM.
  13. * 
  14. * Example of usage:
  15. *     WORD   wInitStatus;
  16. *     HANDLE hSumInfo;
  17. *     char   szTemp[256];
  18. *     LPSTR  szFilePath;
  19. *     WORD   yr, mon, day, hr, min, sec;
  20. *     if (wInitStatus = SumInfoInit()) {
  21. *        ... loop to process files ...
  22. *           szFilePath = ...
  23. *           if (hSumInfo = SumInfoOpenFile(szFilePath)) {
  24. *              if (SumInfoGetString(hSumInfo, PID_TITLE, szTemp, 256)) {
  25. *                 ... do something with szTemp ...
  26. *              }
  27. *              if (SumInfoGetTime(hSumInfo, PID_LASTSAVED, 
  28. *                                 &yr, &mon, &day, &hr, &min, &sec)) {
  29. *                 ... do something with time ...
  30. *              }
  31. *              ...
  32. *              SumInfoCloseFile(hSumInfo);
  33. *           }
  34. *        }
  35. *        SumInfoUninit(wInitStatus);
  36. *     }
  37. *
  38. * Reasons for failure:
  39. *     SumInfoInit:     out of memory
  40. *     SumInfoOpenFile: out of memory
  41. *                      file not found
  42. *                      file is not an OLE 2.0 structured storage file
  43. *                      file does not contain OLE 2.0 summary info
  44. *                      OLE 2.0 summary info is incorrectly formatted
  45. *     SumInfoGet...  : specified property type is not available
  46. *     
  47. * Change log:
  48. * V1.4 94/06/18 Documentation changes only
  49. * V1.3 94/06/06 Change validity checking, because Excel 5.0 files
  50. *                  are slightly invalid
  51. * V1.2 94/03/01 Change STGM_SHARE_DENY_WRITE to STGM_SHARE_DENY_NONE, so
  52. *                  info can be obtained for files currently open in WinWord.
  53. * V1.1 94/01/22 Add wInitStatus parameter to SumInfoInit and SumInfoUninit,
  54. *                  to account for case where CoInitialize already called for  
  55. *                  application.
  56. *               Ensure SumInfoGetString returns zero terminated string.
  57. *               Fix minor typos in documentation.
  58. * V1.0 94/01/20 Initial version.
