Article
02/22/2024

Removes a column from the header of the result view.

Syntax

HRESULT DeleteColumn(
  [in] int nCol
);

Parameters

[in] nCol

A zero-based index that identifies the column to be removed.

Return value

This method can return one of these values.

Remarks

If a column is removed, all columns with indexes greater than the one removed are adjusted down by one.

MMC does not persist in memory any changes made to a column set due to the action of IHeaderCtrl::DeleteColumn, so snap-ins must update persisted column configuration data after deleting columns from a column set. For more information, see IHeaderCtrl2 and Column Persistence.

Notes to Callers

This method returns E_FAIL when an item has already been inserted into the result view.
