Comments

DTWAIN_ArraySetAtString is a specialized version of DTWAIN_ArraySetAt.

 

The DTWAIN_ArraySetAtString 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_ArrayInsertAtString, the DTWAIN_ArraySetAtString 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 string values (i.e. the DTWAIN_ARRAY was created with the DTWAIN_ARRAYSTRING style. See DTWAIN_ArrayCreate for more information).

 

For storing specifically ANSI or Wide strings, use DTWAIN_ArraySetAtANSIString or DTWAIN_ArraySetAtWideString, respectively.

 

TWAIN State Transitions

None.

 

Prerequisite Function Call(s)
