删除非空目录更简单
SHFILEOPSTRUCT shfileop;
shfileop.hwnd = NULL;
shfileop.wFunc = FO_DELETE ;
shfileop.fFlags = FOF_SILENT | FOF_NOCONFIRMATION;
shfileop.pFrom = "c:\\Download1";
shfileop.pTo = "";
shfileop.lpszProgressTitle = "";
shfileop.fAnyOperationsAborted = TRUE;
int nOK = SHFileOperation(&shfileop);
-------------------------------
BOOL DeleteDirectory(LPCTSTR DirName)
{
CFileFind tempFind; //声明一个CFileFind类变量，以用来搜索
char tempFileFind[200]; //用于定义搜索格式
sprintf(tempFileFind,"%s\\*.*",DirName);
//匹配格式为*.*,即该目录下的所有文件
BOOL IsFinded=(BOOL)tempFind.FindFile(tempFileFind);
//查找第一个文件
while(IsFinded)
{
IsFinded=(BOOL)tempFind.FindNextFile(); //递归搜索其他的文件
if(!tempFind.IsDots()) //如果不是"."目录
{
char foundFileName[200];
strcpy(foundFileName,tempFind.GetFileName().GetBuffer(200));
if(tempFind.IsDirectory()) //如果是目录，则递归地调用
{ //DeleteDirectory
char tempDir[200];
sprintf(tempDir,"%s\\%s",DirName,foundFileName);
DeleteDirectory(tempDir);
}
else
{ //如果是文件则直接删除之
char tempFileName[200];
sprintf(tempFileName,"%s\\%s",DirName,foundFileName);
DeleteFile(tempFileName);
}
}
}
tempFind.Close();
if(!RemoveDirectory(DirName)) //删除目录
{
AfxMessageBox("删除目录失败！",MB_OK);
return FALSE;
}
return TRUE;

int SHFileOperation( LPSHFILEOPSTRUCT lpFileOp
);
Parameters
lpFileOp
[in] Pointer to an SHFILEOPSTRUCT structure that contains information this function needs to carry out the specified operation. This parameter must contain a valid value that is not NULL. You are responsibile for validating the value. If you do not validate it, you will experience unexpected results.
Return Value
Syntax
typedef struct _SHFILEOPSTRUCT {
HWND hwnd;
UINT wFunc;
LPCTSTR pFrom;
LPCTSTR pTo;
FILEOP_FLAGS fFlags;
BOOL fAnyOperationsAborted;
LPVOID hNameMappings;
LPCTSTR lpszProgressTitle;
} SHFILEOPSTRUCT, *LPSHFILEOPSTRUCT;
Members
hwnd
Window handle to the dialog box to display information about the status of the file operation.
wFunc
Value that indicates which operation to perform. This member can be one of the following values:
FO_COPY
Copy the files specified in the pFrom member to the location specified in the pTo member.
FO_DELETE
Delete the files specified in pFrom.
FO_MOVE
Move the files specified in pFrom to the location specified in pTo.
FO_RENAME
Rename the file specified in pFrom. You cannot use this flag to rename multiple files with a single function call. Use FO_MOVE instead.
pFrom
Address of a buffer to specify one or more source file names. These names must be fully qualified paths. Standard Microsoft® MS-DOS® wild cards, such as "*", are permitted in the file-name position. Although this member is declared as a null-terminated string, it is used as a buffer to hold multiple file names. Each file name must be terminated by a single NULL character. An additional NULL character must be appended to the end of the final name to indicate the end of pFrom.
pTo
Address of a buffer to contain the name of the destination file or directory. This parameter must be set to NULL if it is not used. Like pFrom, the pTo member is also a double-null terminated string and is handled in much the same way. However, pTo must meet the following specifications:
Wildcard characters are not supported.
Copy and Move operations can specify destination directories that do not exist and the system will attempt to create them. The system normally displays a dialog box to ask the user if they want to create the new directory. To suppress this dialog box and have the directories created silently, set the FOF_NOCONFIRMMKDIR flag in fFlags.
For Copy and Move operations, the buffer can contain multiple destination file names if the fFlags member specifies FOF_MULTIDESTFILES.
Pack multiple names into the string in the same way as for pFrom.
Use only fully-qualified paths. Using relative paths will have unpredictable results.
fFlags
Flags that control the file operation. This member can take a combination of the following flags:
FOF_ALLOWUNDO
Preserve Undo information, if possible. If pFrom does not contain fully qualified path and file names, this flag is ignored.
FOF_CONFIRMMOUSE
Not currently used.
FOF_FILESONLY
Perform the operation on files only if a wildcard file name (*.*) is specified.
FOF_MULTIDESTFILES
The pTo member specifies multiple destination files (one for each source file) rather than one directory where all source files are to be deposited.
FOF_NOCONFIRMATION
Respond with "Yes to All" for any dialog box that is displayed.
FOF_NOCONFIRMMKDIR
Do not confirm the creation of a new directory if the operation requires one to be created.
FOF_NO_CONNECTED_ELEMENTS
Version 5.0. Do not move connected files as a group. Only move the specified files.
FOF_NOCOPYSECURITYATTRIBS
Version 4.71. Do not copy the security attributes of the file.
FOF_NOERRORUI
Do not display a user interface if an error occurs.
FOF_NORECURSION
Only operate in the local directory. Don't operate recursively into subdirectories.
FOF_NORECURSEREPARSE
Treat reparse points as objects, not containers. You must set _WIN32_WINNT to 5.01 or later to use this flag. See Shell and Common Controls Versions for further discussion of versioning.
FOF_RENAMEONCOLLISION
Give the file being operated on a new name in a move, copy, or rename operation if a file with the target name already exists.
FOF_SILENT
Do not display a progress dialog box.
FOF_SIMPLEPROGRESS
Display a progress dialog box but do not show the file names.
FOF_WANTMAPPINGHANDLE
If FOF_RENAMEONCOLLISION is specified and any files were renamed, assign a name mapping object containing their old and new names to the hNameMappings member.
FOF_WANTNUKEWARNING
Version 5.0. Send a warning if a file is being destroyed during a delete operation rather than recycled. This flag partially overrides FOF_NOCONFIRMATION.
fAnyOperationsAborted
Value that receives TRUE if the user aborted any file operations before they were completed, or FALSE otherwise.
hNameMappings
A handle to a name mapping object containing the old and new names of the renamed files. This member is used only if the fFlags member includes the FOF_WANTMAPPINGHANDLE flag. See Remarks for more details.
lpszProgressTitle
Address of a string to use as the title of a progress dialog box. This member is used only if fFlags includes the FOF_SIMPLEPROGRESS flag.
Remarks
If the pFrom or pTo members are unqualified names, the current directories are taken from the global current drive and directory settings as managed by the GetCurrentDirectory and SetCurrentDirectory functions.
If pFrom is set to a file name, deleting the file with FO_DELETE will not move it to the Recycle Bin, even if the FOF_ALLOWUNDO flag is set. You must use a full path.
There are two versions of this structure, an ANSI version (SHFILEOPSTRUCTA) and a Unicode version (SHFILEOPSTRUCTW). The Unicode version is identical to the ANSI version, except that wide character strings (LPCWSTR) are used in place of ANSI character strings (LPCSTR). On Microsoft Windows® 98 and earlier, only the ANSI version is supported. On Microsoft Windows NT® 4.0 and later, both the ANSI and Unicode versions of this structure are supported. SHFILEOPSTRUCTW and SHFILEOPTSTRUCTA should never be used directly; the appropriate structure is redefined as SHFILEOPSTRUCT by the precompiler depending on whether the application is compiled for ANSI or Unicode. SHNAMEMAPPING has similar ANSI and Unicode versions. For ANSI applications, hNameMappings points to an int followed by an array of ANSI SHNAMEMAPPING structures. For Unicode applications, hNameMappings points to an int followed by an array of Unicode SHNAMEMAPPING structures. However, on Windows NT 4.0 and later, SHFileOperation always returns a handle to a Unicode set of SHNAMEMAPPING structures. If you want applications to be functional with all versions of Windows, the application must employ conditional code to deal with name mappings. For example:
x = SHFileOperation(&shop);
...
if (fWin9x) {
HandleAnsiNameMappings(shop.hNameMappings);
}
else {
HandleUnicodeNameMappings(shop.hNameMappings);
}
Treat hNameMappings as a pointer to a structure whose members are an UINT value followed by a pointer to an array of SHNAMEMAPPING structures, for example:
struct HANDLETOMAPPINGS {
UINT uNumberOfMappings; // number of mappings in array
LPSHNAMEMAPPING lpSHNameMapping; // pointer to array of mappings
};
The UINT value is set to the number of SHNAMEMAPPING structures in the array. Each SHNAMEMAPPING structure contains the old and new path for one of the renamed files.
Note The handle must be freed with SHFreeNameMappings.
For a complete application that uses the SHFILEOPSTRUCT structure and explains how to set up the SHNAMEMAPPING structure, see the Knowledge Base Article Q151799 at http://support.microsoft.com/support/kb/articles/Q151/7/99.asp.

int SHFileOperation(LPSHFILEOPSTRUCT lpFileOp);
直接删除目录或文件 无论目录是否为空
而且可以定制是否删除到垃圾箱 是否显示进度 这是一个 SHELL函数
在导入库中加入 shell32.lib 头文件是shellapi.h
爽吧
Minimum DLL Version shell32.dll version 4.0 or later
Custom Implementation No
Header shellapi.h
Import library shell32.lib
Minimum operating systems Windows NT 4.0, Windows 95

如果你要删除
lpFileOp－》wFunc ＝ FO_DELETE
SO EASY 楼主是吧Top
