  1. SHFileOperation
  2. 函數功能描述:文件操作，與 Shell 的動作相同.
  3. 函數原型：
  4. #include<shellapi.h>
  5. WINSHELLAPI int WINAPI SHFileOperation(LPSHFILEOPSTRUCT lpFileOp);
  6. 參數：
  7. typedef struct _SHFILEOPSTRUCT
  8. {
  9. HWND hwnd; //父窗口句柄
  10. UINT wFunc; //要執行的動作
  11. LPCTSTR pFrom; //源文件路徑，可以是多個文件
  12. LPCTSTR pTo; //目標路徑，可以是路徑或文件名
  13. FILEOP_FLAGS fFlags; //標志，附加選項
  14. BOOL fAnyOperationsAborted; //是否可被中斷
  15. LPVOID hNameMappings; //文件映射名字，可在其它 Shell 函數中使用
  16. LPCTSTR lpszProgressTitle; // 只在 FOF_SIMPLEPROGRESS 時，指定對話框的標題。
  17. } SHFILEOPSTRUCT, FAR *LPSHFILEOPSTRUCT;
  18. =======================
  19. wFunc 可以為：
  20. /FO_MOVE 0x0001 移動文件
  21. FO_COPY 0x0002 復制文件
  22. FO_DELETE 0x0003 刪除文件，只使用 pFrom
  23. FO_RENAME 0x0004 文件重命名
  24. fFlags可以為：
  25. FOF_MULTIDESTFILES 0x0001 //pTo 指定了多個目標文件，而不是單個目錄
  26. FOF_CONFIRMMOUSE 0x0002
  27. FOF_SILENT 0x00044 // 不顯示一個進度對話框
  28. FOF_RENAMEONCOLLISION 0x0008 // 碰到有抵觸的名字時，自動分配前綴
  29. FOF_NOCONFIRMATION 0x0010 // 不對用戶顯示提示
  30. FOF_WANTMAPPINGHANDLE 0x0020 // 填充 hNameMappings 字段，必須使用 SHFreeNameMappings 釋放
  31. FOF_ALLOWUNDO 0x0040 // 允許撤銷
  32. FOF_FILESONLY 0x0080 // 使用 *.* 時, 只對文件操作
  33. FOF_SIMPLEPROGRESS 0x0100 // 簡單進度條，意味者不顯示文件名。
  34. FOF_NOCONFIRMMKDIR 0x0200 // 建新目錄時不需要用戶確定
  35. FOF_NOERRORUI 0x0400 // 不顯示出錯用戶界面
  36. FOF_NOCOPYSECURITYATTRIBS 0x0800 // 不復制 NT 文件的安全屬性
  37. FOF_NORECURSION 0x1000 // 不遞歸目錄
  38. 返回值：
  39. 函數成功返回 0 ，失敗返回非 0 。
  40. 例子：
  41. 1. 將 C:\Test.txt 拷貝到 D:\
  42. SHFILEOPSTRUCT lpsh;
  43. ZeroMemory(&lpsh,sizeof(lpsh));
  44. lpsh.hwnd= HWND_DESKTOP;
  45. lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;
  46. lpsh.wFunc=FO_COPY; // FO_MOVE 則是移動
  47. lpsh.pFrom= "C:\Test.txt";
  48. lpsh.pTo = "D:\"
  49. if( 0 != SHFileOperation(&lpsh))
  50. {
  51. AfxMessageBox("復制文件出錯,請檢查");
  52. return ;
  53. }
  54. 2. 刪除 D:\Test.txt
  55. SHFILEOPSTRUCT lpsh;
  56. ZeroMemory(&lpsh,sizeof(lpsh));
  57. lpsh.hwnd= HWND_DESKTOP;
  58. lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;
  59. lpsh.wFunc=FO_DELETE;
  60. lpsh.pFrom= "D:\Test.txt";
  61. if( 0 != SHFileOperation(&lpsh))
  62. {
  63. AfxMessageBox("刪除文件出錯,請檢查");
  64. return ;
  65. }
  66. 3.重命名
  67. SHFILEOPSTRUCT lpsh;
  68. ZeroMemory(&lpsh,sizeof(lpsh));
  69. lpsh.hwnd= HWND_DESKTOP;
  70. lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;
  71. lpsh.wFunc=FO_RENAME;
  72. lpsh.pFrom= "D:\Test.txt";
  73. lpsh.pTo = "D:\Test2.txt";
  74. if( 0 != SHFileOperation(&lpsh))
  75. {
  76. AfxMessageBox("重命名文件出錯!");
  77. return ;
  78. }
  79. 注意事項：
  80. 參數pTo、pFrom必須是以 雙0 結束的，原文為：
  81. pFrom
  82. Pointer to a buffer that specifies one or more source file names. Multiple names must be null-separated. The list of names must be double null-terminated.
  83. a.如果是直接賦值：
  84. WCHAR strSrc[MAX_PATH] = _T("g:\\123");
    WCHAR strDst[MAX_PATH] = _T("g:\\456");
  85. 這樣就可以成功編譯。
  86. b.如果pTo、pFrom從CString獲得，則：
  87. WCHAR SrcFolder[MAX_PATH],DestFolder[MAX_PATH];
  88. wcscpy_s(SrcFolder, Source);
    wcscpy_s(DestFolder,m_Path);
    SrcFolder[wcslen(SrcFolder) + 1] = 0;
    DestFolder[wcslen(DestFolder) + 1] = 0;    （其中，Source與m_Path是在其他地方獲取的值）
  89. 造成這種差異的原因是：CString在結尾並沒有"\0"，所以需要我們添加。
  90. 4.VB
  91. Public Declare Function SHFileOperation Lib "shell32.dll" Alias "SHFileOperationA" (lpFileOp As SHFILEOPSTRUCT) As Long
  92. Public Const FO_COPY = &H2
  93. Public Const FOF_ALLOWUNDO = &H40
  94. Public Sub ShellCopyFile(Source As String, Dest As String)
  95. Dim result As Long
  96. Dim fileop As SHFILEOPSTRUCT
  97. With fileop
  98. .hwnd = 0
  99. .wFunc = FO_COPY
  100. .pFrom = Source & vbNullChar & vbNullChar
  101. .pTo = Dest & vbNullChar & vbNullChar
  102. .fFlags = FOF_ALLOWUNDO
  103. End With
  104. result = SHFileOperation(fileop)
  105. If result <> 0 Then
  106. 'Msgbox the error that occurred in the API.
  107. MsgBox Err.LastDllError, vbCritical Or vbOKOnly
  108. Else
  109. If fileop.fAnyOperationsAborted <> 0 Then
  110. MsgBox "Operation Failed", vbCritical Or vbOKOnly
  111. End If
  112. End If
  113. End Sub
