Syntax

#include "Ltfil.h"

L_LTFIL_API L_INT L_SetTXTOptions(pTxtOptions)

Parameters

pFILETXTOPTIONS pTxtOptions

Pointer to the FILETXTOPTIONS structure that contains the options to use when loading TXT.

Returns

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

Comments

The uStructSize member of the FILETXTOPTIONS structure must be set before calling this function. If a TXT file is loaded without first setting the options using this function, the following default values will be used for the FILETXTOPTIONS members:

Member	Default Value
bEnabled	FALSE
crFontColor	RGB(0, 0, 0)
crHighlight	RGB(0xFF, 0xFF, 0xFF)
nFontSize	12
pFaceName	"Courier New"
bBold	FALSE
bItalic	FALSE
bUnderLine	FALSE
bStrikeThrough	FALSE
