SHGetFileInfo info

Retrieves information about an object in the file system, such as a file, a folder, a directory, or a drive root.

WINSHELLAPI DWORD WINAPI SHGetFileInfo(

    LPCTSTR pszPath,

    DWORD dwFileAttributes,

    SHFILEINFO FAR *psfi,

    UINT cbFileInfo,

    UINT uFlags

   );

Parameters

pszPath
Pointer to a buffer that contains the path and filename. Both absolute and relative paths are valid. If uFlags includes the SHGFI_PIDL, value pszPath must be the address of an ITEMIDLIST structure that contains the list of item identifiers that uniquely identifies the file within the shell’s name space.

This string can use either short (the 8.3 form) or long filenames.

dwFileAttributes
Array of file attribute flags (FILE_ATTRIBUTE_ values). If uFlags does not include the SHGFI_USEFILEATTRIBUTES value, this parameter is ignored.
psfi and cbFileInfo
Address and size, in bytes, of the SHFILEINFO structure that receives the file information.
uFlags
Flag that specifies the file information to retrieve. This parameter can be a combination of the following values:

SHGFI_ATTRIBUTES

Retrieves the file attribute flags. The flags are copied to the dwAttributes member of the structure specified by psfi.

SHGFI_DISPLAYNAME

Retrieves the display name for the file. The name is copied to the szDisplayName member of the structure specified by psfi.

The returned display name uses the long filename, if any, rather than the 8.3 form of the filename.

SHGFI_EXETYPE

Returns the type of the executable file if pszPath identifies an executable file. For more information, see the comments below.

SHGFI_ICON

Retrieves the handle of the icon that represents the file and the index of the icon within the system image list. The handle is copied to the hIcon member of the structure specified by psfi, and the index is copied to the iIcon member. The return value is the handle of the system image list.

SHGFI_ICONLOCATION

Retrieves the name of the file that contains the icon representing the file. The name is copied to the szDisplayName member of the structure specified by psfi.

SHGFI_LARGEICON

Modifies SHGFI_ICON, causing the function to retrieve the file’s large icon.

SHGFI_LINKOVERLAY

Modifies SHGFI_ICON, causing the function to add the link overlay to the file’s icon.

SHGFI_OPENICON

Modifies SHGFI_ICON, causing the function to retrieve the file’s open icon. A container object displays an open icon to indicate that the container is open.

SHGFI_PIDL

Indicates that pszPath is the address of an ITEMIDLIST structure rather than a path name.

SHGFI_SELECTED

Modifies SHGFI_ICON, causing the function to blend the file’s icon with the system highlight color.

SHGFI_SHELLICONSIZE

Modifies SHGFI_ICON, causing the function to retrieve a shell-sized icon. If this flag is not specified, the function sizes the icon according to the system metric values.

SHGFI_SMALLICON

Modifies SHGFI_ICON, causing the function to retrieve the file’s small icon.

SHGFI_SYSICONINDEX

Retrieves the index of the icon within the system image list. The index is copied to the iIcon member of the structure specified by psfi. The return value is the handle of the system image list.

SHGFI_TYPENAME

Retrieves the string that describes the file’s type. The string is copied to the szTypeName member of the structure specified by psfi.

SHGFI_USEFILEATTRIBUTES

Indicates that the function should use the dwFileAttributes parameter.

To retrieve the executable file type, uFlags must specify only SHGFI_EXETYPE. The return value specifies the type of the executable file:

0

Nonexecutable file or an error condition.

LOWORD = NE or PE
HIWORD = 3.0, 3.5, or 4.0

Windows application

LOWORD = MZ
HIWORD = 0

MS-DOS .EXE, .COM or .BAT file

LOWORD = PE
HIWORD = 0

Win32 console application

Return Values
