The DTWAIN_ArrayAddStringN function adds N copies of a string value to the end of a DTWAIN_ARRAY.

 

DTWAIN_BOOL DTWAIN_ArrayAddStringN (

DTWAIN_ARRAY

Array,

LPCTSTR

Value,

LONG

NumCopies );

 

Parameters

Array

DTWAIN_ARRAY that the value will be added to.

 

Value

Pointer to character buffer.

 

NumCopies

Number of copies of Value to add to the array.


Return Values

TRUE if successful, FALSE otherwise.  If the function returns FALSE, call DTWAIN_GetLastError() to get extended information.

 

Character specific version

ANSI version:

DTWAIN_ArrayAddStringNA

Unicode version:

DTWAIN_ArrayAddStringNW

 

Comments

The DTWAIN_ArrayAddStringN function appends NumCopies of the contents of the buffer located at Value to the end of the DTWAIN_ARRAY Array.  The number of elements in the DTWAIN_ARRAY is increased by NumCopies.  

 

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)

 

It is the responsibility of the application to store the correct string type (ANSI / Unicode) in the string array.  For example, if your application attempts to store char-based (ANSI) strings in a DTWAIN_ARRAY that was created to take wide (Unicode) strings, DTWAIN has no way of checking if the string is of the correct type, thus your application will more than likely not behave correctly when attempting to access the strings within the array.


TWAIN State Transitions

None.
