SHGetIconOverlayIndex function

Returns the index of the overlay icon in the system image list.

Syntax


int SHGetIconOverlayIndex(
  _In_opt_  LPCTSTR pszIconPath,
  int iIconIndex
);

Parameters

pszIconPath [in, optional]

Type: LPCTSTR

A pointer to a null-terminated string of maximum length MAX_PATH that contains the fully qualified path of the file that contains the icon.

iIconIndex

Type: int

The icon's index in the file pointed to by pszIconPath. To request a standard overlay icon, set pszIconPath to NULL, and iIconIndex to one of the following:

IDO_SHGIOI_SHARE (0x0FFFFFFF)

The overlay icon that indicates a shared folder.

IDO_SHGIOI_LINK (0x0FFFFFFE)

The overlay icon that indicates a linked folder or file.

IDO_SHGIOI_SLOWFILE (0x0FFFFFFD)

The overlay icon that indicates a slow file.

IDO_SHGIOI_DEFAULT (0x0FFFFFFC)

Windows 7 and later. The overlay icon that indicates that the item is the default in a set. One example is the default printer.

Return value

Type: int

Returns the index of the overlay icon in the system image list if successful, or -1 otherwise.

Remarks

Icon overlays are part of the system image list. They have two identifiers. The first is a one-based overlay index that identifies the overlay relative to other overlays in the image list. The other is an image index that identifies the actual image. These two indexes are equivalent to the values that you assign to the iOverlay and iImage parameters, respectively, when you add an icon overlay to a private image list with ImageList_SetOverlayImage. SHGetIconOverlayIndex returns the overlay index. To convert an overlay index to its equivalent image index, call INDEXTOOVERLAYMASK.

Note  After the image has been loaded into the system image list during initialization, it cannot be changed. The file name and index specified by pszIconPath and iIconIndex are used only to identify the icon overlay. SHGetIconOverlayIndex cannot be used to modify the system image list.
