#include "ltwrappr.h"

static L_INT LFileSettings::IgnoreFilters(pszFilters)

L_TCHAR * pszFilters;

character string containing filters

Specifies which file filters LEADTOOLS should NEVER load, even if present.

Parameter	Description
pszFilters	Character string containing which filters should be ignored and therefore not loaded. pszFilters has the same format as in LFileSettings::PreLoadFilters .

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Use this function if you never want to load a particular file filter(s).

The files specified in LFileSettings::PreLoadFilters take priority over the files specified in LFileSettings::IgnoreFilters. This means that if the filter is present in pszFilters for both methods, then the filter will be loaded and will not be ignored.

Note that LFileSettings::IgnoreFilters has effect only if called prior to loading, saving or getting information about a file. In addition, LFileSettings::PreLoadFilters must be called before LFileSettings::IgnoreFilters for LFileSettings::IgnoreFilters to work properly. For more information, refer to Loading File Filters.

In case the current ignored filters list should be changed, call the LFileSettings::GetIgnoreFilters function before calling this function.
