Comments

DTWAIN_ArraySetAtWideString is a specialized version of DTWAIN_ArraySetAt.

 

The DTWAIN_ArraySetAtWideString copies the string pointed to by Value to a position in the DTWAIN_ARRAY Array.   The Index argument is the position to place the value, and must be in the range of 0 to n-1 where n is the number of elements in the array.   The string must be a null-terminated string.

 

Unlike DTWAIN_ArrayInsertAtWideString, the DTWAIN_ArraySetAtWideString function replaces the value located at the position instead of inserting the value and moving existing elements down.

 

This function will only work for DTWAIN_ARRAY's that can store wide (Unicde) or 16-bit character strings values.  The DTWAIN_ARRAY must be created  with

 

1) The DTWAIN_ARRAYWIDESTRING style

or

2) with the DTWAIN_ARRAYSTRING style if using the Unicode version of the DTWAIN library (DTWAIN32U.DLL, DTWAIN64U.DLL).

 

To insert 8-bit character strings, use DTWAIN_ArraySetAtANSIString.

 

TWAIN State Transitions

None.

 

Prerequisite Function Call(s)

DTWAIN_SysInitialize
