FM_GETFILESELLFN

A File Manager extension sends an FM_GETFILESELLFN message to retrieve information about a selected file from the active File Manager window (either the directory window or the Search Results window). The selected file can have a long filename.

Parameters

wParam

Specifies the zero-based index of the selected file to retrieve.

lParam

Points to an FMS_GETFILESEL structure that receives information about the selection. The FMS_GETFILESEL structure has the following form:

#include <wfext.h>

typedef struct tagFMS_GETFILESEL { /* fmsgfs */
    UINT  wTime;
    UINT  wDate;
    DWORD dwSize;
    BYTE  bAttr;
    char  szName[260];
} FMS_GETFILESEL;

Return Value

The return value is the zero-based index of the selected file that was retrieved.

Comments

Only extensions that support long filenames (for example, network-aware extensions) should use this message.

An extension can use the FM_GETSELCOUNT message to obtain the count of selected files.

The szName member of the FMS_GETFILESEL structure consists of an OEM character string. Before displaying this string, an extension should use the OemToAnsi function to convert the string to a Windows ANSI character string. If a string is to be passed to the file system (MS-DOS), an extension should not convert it.
