SHGetSpecialFolderPath Function

Retrieves the path of a special folder, identified by its CSIDL.

Syntax

BOOL SHGetSpecialFolderPath(      

    HWND hwndOwner,
    LPTSTR lpszPath,
    int nFolder,
    BOOL fCreate
);

Parameters

hwndOwner
A handle to the owner window that the client should specify if it displays a dialog box or message box.
lpszPath
A pointer to a null-terminated string that receives the drive and path of the specified folder. This buffer must be at least MAX_PATH characters in size.
nFolder
A CSIDL that identifies the folder of interest. If a virtual folder is specified, this function will fail.
fCreate
Indicates whether the folder should be created if it does not already exist. If this value is nonzero, the folder will be created. If this value is zero, the folder will not be created.

Return Value

Returns TRUE if successful, or FALSE otherwise.

Remarks

The Microsoft Internet Explorer 4.0 Desktop Update must be installed for this function to be available.

With Microsoft Windows 2000, this function is superseded by ShGetFolderPath. You can use this function on earlier systems by including the redistributable DLL, ShFolder.dll.

地下是关于路径设置参数CSIDL的说明
CSIDL Note In Windows Vista, these values have been replaced by KNOWNFOLDERID values. See that topic for a list of the new constants and their corresponding CSIDL values. For convenience, corresponding KNOWNFOLDERID values are also noted here for each CSIDL value.

The CSIDL system is supported under Windows Vista for compatibility reasons. However, new development should use KNOWNFOLDERID values rather than CSIDL values.

CSIDL (constant special item ID list) values provide a unique system-independent way to identify special folders used frequently by applications, but which may not have the same name or location on any given system. For example, the system folder may be "C:/Windows" on one system and "C:/Winnt" on another. These constants are defined in Shlobj.h. A subset of them is also defined in Shfolder.h.

Constants

CSIDL_ADMINTOOLS (FOLDERID_AdminTools)
Version 5.0 . The file system directory that is used to store administrative tools for an individual user. The Microsoft Management Console (MMC) will save customized consoles to this directory, and it will roam with the user.

CSIDL_ALTSTARTUP (FOLDERID_Startup)

CSIDL_APPDATA (FOLDERID_RoamingAppData)
Version 4.71. The file system directory that serves as a common repository for application-specific data. A typical path is C:/Documents and Settings/username/Application Data.

Flags

CSIDL_FLAG_CREATE (KF_FLAG_CREATE)
Version 5.0. Combine with another CSIDL to force the creation of the associated folder if it does not exist.

CSIDL_FLAG_DONT_UNEXPAND (KF_FLAG_DONT_UNEXPAND)
Combine with another CSIDL constant to ensure the expansion of environment variables.

CSIDL_FLAG_DONT_VERIFY (KF_FLAG_DONT_VERIFY)
Combine with another CSIDL constant, except for CSIDL_FLAG_CREATE , to return an unverified folder path with no attempt to create or initialize the folder.

CSIDL_FLAG_NO_ALIAS (KF_FLAG_NO_ALIAS)
Combine with another CSIDL constant to ensure the retrieval of the true system path for the folder, free of any aliased placeholders such as %USERPROFILE%, returned by SHGetFolderLocation. This flag has no effect on paths returned by SHGetFolderPath.

CSIDL_FLAG_PER_USER_INIT

CSIDL_FLAG_MASK
A mask for any valid CSIDL flag value.

Remarks

These values supersede the use of environment variables for this purpose. They are in turn superseded in Windows Vista and later by the KNOWNFOLDERID values.

A CSIDL is used in conjunction with one of four Shell functions, SHGetFolderLocation, SHGetFolderPath, SHGetSpecialFolderLocation, and SHGetSpecialFolderPath, to retrieve a special folder's path or pointer to an item identifier list (PIDL).

Combine CSIDL_FLAG_CREATE with any of the other CSIDLs, except for CSIDL_FLAG_DONT_VERIFY, to force the creation of the associated folder. The remaining CSIDLs correspond to either file system folders or virtual folders. Where the CSIDL identifies a file system folder, a commonly used path is given as an example. Other paths may be used. Some CSIDLs can be mapped to an equivalent %VariableName% environment variable. CSIDLs are more reliable, however, and should be used if possible.
