BOOL SetFilter( int nType, LPVOID data, BOOL bUndo = FALSE )

Parameters

nType: [input]the column filter type enum; {; COLUMN_FILTER_TYPE_NONE = -1,; COLUMN_FILTER_TYPE_CHECK_LIST = 0,; COLUMN_FILTER_TYPE_CUSTOM,; COLUMN_FILTER_TYPE_COMMAND,; COLUMN_FILTER_TYPE_DATASET_FUNC,; };
data: [input]struct with filter settings. Each filter type has its own struct. See examples for detail.
bUndo: [input] whether the action should be undoable.

Return

TRUE if success
