Members
scid
Type: SHCOLUMNID
A SHCOLUMNID structure that uniquely identifies the column.
vt
Type: VARTYPE
The native VARIANT type of the column's data.
fmt
Type: DWORD
List view format. This member is normally set to LVCFMT_LEFT.
cChars
Type: UINT
The default width of the column, in characters.
csFlags
Type: DWORD
Flags indicating the default column state. It can be a combination of the following flags.
SHCOLSTATE_TYPE_STR
A string.
SHCOLSTATE_TYPE_INT
An integer.
SHCOLSTATE_TYPE_DATE
A date.
SHCOLSTATE_ONBYDEFAULT

SHCOLSTATE_SLOW

Provided by a handler, not the folder object.
SHCOLSTATE_SECONDARYUI
Not displayed in the shortcut menu, but listed in the More... dialog box.
SHCOLSTATE_HIDDEN
Not displayed in the user interface.
