L_LTDOC2_API L_INT EXT_FUNCTION L_Doc2RemoveItemFromUserDictionary(hDoc, pSection, pUDitem, uMask)

Removes the specified section item from the specified section in the User dictionary.


L_HDOC2 hDoc

Handle to the OCR document.

L_CHAR * pSection

Name of the section from which the item should be deleted.

L_WCHAR * pUDitem

Pointer to a UNICODE string containing the word to be deleted. (The string must be terminated with a double zero.)

L_UINT32 uMask

Attribute for the pUDitem to be deleted. Possible values are:

Value Meaning
DOC2_USER_DICT_LITERAL [0x0000] Delete the literal dictionary. This is the default value.
DOC2_USER_DICT_REGULAR_EXPRESSION [0x0001] Delete the regular expression dictionary.


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


When the characters to be deleted are contained in the ANSI (1252) Code Page, the easiest way to define the pUDitem string is with a wide-character-string literal, L"characters".

When there are two pUDItems items in the pSection with the same name, but with different attributes, the uMask parameter will determine the item to be deleted.

Deleting the last User dictionary item from a section causes the section to be removed automatically from the User dictionary.
